Environmental factors likely behind autism epidemic

Friday, April 3rd, 2009

From PANUPS: 

Changes in doctors’ diagnoses cannot explain the sevenfold increase in autism since 1990, a new study shows. Rather, “It’s time to start looking for the environmental culprits responsible for the remarkable increase in the rate of autism in California,” said Irva Hertz-Picciotto, an epidemiology professor at University of California, Davis who led the study.

In California alone, more than 3,000 new cases of autism were reported in 2006, up from just 205 in 1990. The increase had previously been attributed to a change in diagnoses, but the new study concludes that those factors can’t explain most of the increases, reports Marla Cone of the Environmental Health News.

“Mothers of autistic children were twice as likely to use pet flea shampoos, which contain organophosphates or pyrethroids, according to one study that has not yet been published,” says Hertz-Picciota. “Another new study has found a link between autism and phthalates, which are compounds used in vinyl and cosmetics.

Other household products such as antibacterial soaps also could have ingredients that harm the brain by changing immune systems,” she added.

The chemistry of beauty

What’s in all those beauty products? The truth isn’t pretty.

By Sena Christian

Twenty-six years into life and I still don’t quite grasp beauty. I know what it’s supposed to be: high cheekbones, long neck, plump lips, glossy hair, no cellulite, eternal youth. These idealistic standards are demanded of American women, what Naomi Wolf calls “the beauty myth,” the societal force that keeps women and girls vulnerable, insecure and preoccupied. And it does.

Women use an average of a dozen personal-care products a day and men use about six. Female teenagers tend to use even more. My own daily regime involves the application of 10 products, including shampoo and conditioner, toothpaste, deodorant, face wash, moisturizer, body lotion, foundation, mascara and eyeliner.

But makeup and tanning creams and teeth-whitening strips and age-defying lotions aren’t only about the outside appearance. We’re putting more and more chemical compounds into ourselves through personal-care products, with incomplete knowledge of the affect of these synthetic materials on our bodies and health, and for pregnant women, the health of their unborn babies.

You know those 12 products women use daily? That adds up to some 168 chemical ingredients, and men’s habits total about 85 ingredients. I deposit about 110 chemicals into my body every day. Add to these numbers the fact that toxins pervade our environment—our drinking water, air, food and plastics. We’re each contaminated with hundreds of industrial chemicals, including plasticizers, flame retardants, stain repellents and pesticides that have been linked to cancer, immune-system damage and reproductive and developmental toxicity.

Meanwhile, chronic illness and disease in the United States is on the rise, affecting almost one-half of the population, according to the U.S. Centers for Disease Control and Prevention. As the use of synthetic chemicals post-World War II increased, so did infertility, birth defects in males, testicular cancer and learning disabilities. Breast cancer used to be relegated to post-menopausal women. Now young women in their 20s are afflicted.

As science tries to get a handle on the situation and figure out what direct link, if any, exists between industrial chemicals and the chronic illnesses that plague us, the beauty industry conveniently uses this uncertainty to excuse its continued use of toxic chemicals. This industry is the least regulated under the U.S. Food and Drug Administration, an agency that essentially looks the other way as companies go about their business, leaving the American public to cross our fingers and hope that when it comes to consumer safety, the $250 billion global personal-care products industry tells us the truth.

Maybe I don’t yet understand beauty, and maybe I never will. But I know one thing: I sure was interested in finding out more about all those chemicals.

The beauty industry
The fog dissipated by the time I arrived in Berkeley on a recent summer morning to meet up with Stacy Malkan, cofounder of the Campaign for Safe Cosmetics, at a coffee shop near the UC Berkeley campus.

It was here where I first thought critically about gender representations and what was meant by “the personal is political.” It was here where my mind was torn apart in women’s studies classes, only to piece itself back together again as societal expectations in the post-college world weighed down on me. And I eventually gave in. Here I read the works of Andrea Dworkin, Cherrie Moraga and Angela Davis, and sought consciousness-raising of the highest order. But all I found was a handful of liberal feminists whose main political activism of the school year was performing in the annual production of The Vagina Monologues. My quest to find real-life feminists left me thoroughly disappointed.

Malkan looked as I expected from the cover of her book, Not Just a Pretty Face: The Ugly Side of the Beauty Industry—bright blue eyes, a welcoming smile. She leaned forward as she laughed, which was often, and cradled her drink. She was fresh off a 30-city book tour through 13 states to promote her book, released last October. The previous weekend she’d participated in an event in San Francisco with Teens for Safe Cosmetics, a group of teenagers from Marin County, which has one of the highest rates of breast cancer in the nation. The young women gave free manicures using water-based nail polish. Last year, the group held an event called Project Prom and wore prom dresses and tiaras with combat boots to “combat” all the toxic makeup teenagers wear for prom night.

“The most exciting part of this work is seeing young people learning about science, and organizing and lobbying and learning that they have the power to make change,” said Malkan, who obsessed over cosmetics as a teenager, exposing herself to more than 200 chemicals a day before getting on the school bus in the town of Lynn, Mass., where she grew up.

Malkan has spent the last several years working to reduce the prevalence of toxins in our lives, including those found in makeup. In 2001, she joined Health Care Without Harm, a nonprofit organization founded in 1996 after the U.S. Environmental Protection Agency identified medical-waste incinerators as a leading source of dioxin, a potent carcinogen.

Dioxin received national attention back in the late 1970s when residents of Love Canal, a neighborhood in Niagara Falls, N.Y., experienced high rates of miscarriage, birth defects and toxic material in the milk of nursing mothers. Later, a chemical-waste dump—containing dioxin—was discovered buried beneath the neighborhood.

Medical devices made of polyvinyl chloride plastic create dioxin when manufactured or burned and leach phthalates into hospital patients. Phthalates are a class of industrial chemicals linked to defects in male development. Known as “endocrine disruptors,” phthalates can block male hormones, called androgens, and the production of testosterone needed for masculinization, as shown in hundreds of animal studies.

Industry produces one billion tons of phthalates per year worldwide, and these chemicals are commonly used in toys, food packaging, vinyl flooring, pharmaceuticals, personal-care products and, of course, medical devices. So Health Care Without Harm pushed hospitals to phase out these devices, an effort that has been largely successful.

Malkan currently works for the Campaign for Safe Cosmetics, a nonprofit organization housed in the Breast Cancer Fund headquarters in San Francisco, which she co-founded with the executive director of Health Care Without Harm in 2002.

Back in 2000, the Centers for Disease Control and Prevention released a study that found seven different types of phthalates in 289 people tested. Inside everyone was dibutyl phthalate, a commonly used plasticizer and suspected teratogen that interferes with fetus development and causes birth defects. Dibutyl phthalate is the most toxic phthalate. These results surprised the scientific community. But then scientists broke down the findings by age and gender, determining something else of particular interest: Women between the ages of 20 and 40—childbearing age—had the highest levels of dibutyl phthalate in their bodies.

Around the same time, Jane Houlihan of the Environmental Working Group, a watchdog organization based in Washington, D.C., discovered that dibutyl phthalate was a common ingredient in nail polishes. Dibutyl phthalate came to be known as part of a “toxic trio” of chemicals found in about half of the nail polishes on the market. Toluene, an aromatic hydrocarbon used as solvent in paints, paint thinners, gasoline and glue (people inhale its fumes for illegal recreational drug use) was found, along with formaldehyde, which the EPA lists as a probable human carcinogen, meaning the scientific link between the substance and cancer is compelling but inconclusive. Many companies would later voluntarily remove these chemicals from their products.

Houlihan upped the ante even more with the “Skin Deep” report she coauthored in 2005, which found that one-third of personal-care products contained at least one ingredient linked to cancer, 60 percent contained chemicals that can act like estrogen or disrupt hormones in the body, and 45 percent contained an ingredient that may be harmful to the reproductive system or a baby’s development.

Clearly, the Campaign for Safe Cosmetics has had plenty of work to keep them busy.

Malkan loves Berkeley, where she’s lived for the last four years, especially the city’s political opportunities and proximity to the state Capitol. We sat drinking coffee only a few blocks from the university campus where Tyrone Hayes, a developmental endocrinologist, discovered that atrazine—a widely used herbicide that’s been traced in drinking water—caused male frogs to grow ovaries in their testes. He later accused a corporate sponsor of the research of trying to delay and discredit his findings. The sponsor was Syngenta, the primary manufacturer of atrazine.

I love Berkeley, because over the years it’s the closest I’ve found to a true feminist hub, although it’s not quite perfect. A few years ago, I heard the word phthalate for the first time as my hippie friend Laurie scoured shelves for face moisturizer without the chemical at the Elephant Pharmacy, a local institution where a woman could obtain emergency contraception without a doctor’s prescription before the FDA approved this status, or take yoga and nutrition classes—a place where my girlfriends and I felt equipped to make smart choices about our own bodies.

“We need to take an objective look at the beauty industry and what they’re telling us,” Malkan said. “We trust and believe in our beauty products. But billions of dollars go into marketing to make us feel like we have to have these products in order to be whole.”

Women, and increasingly girls, are routinely held up against unattainable images of outer beauty, and we’ll paint, starve and disfigure ourselves trying to get there. Forget having a strong sense of self. No, we must feel continually compelled to change into something different.

As I left Berkeley and returned to Sacramento, I remembered something I learned from one particularly insightful class of advanced feminist theory: It’s OK to be pissed off.

In fact, you probably should be.

Pretty poison
Back in the late 1800s, skin whitening was a widespread face-altering practice done by African-American women hoping to escape the psychological binds left over from slavery. Lightening creams continue to be big sellers today among both African-American and Asian women. Many of the creams contain hydroquinone, an animal carcinogen that is toxic to the brain, immune system and reproductive system. The European Union banned hydroquinone, but the United States has not.

Hair products marketed to African-American women promise to make hair stronger and more manageable. These products contain placenta extract that have estrogenic hormones. Scientists believe that women with more exposure to estrogen in their lifetime have a greater risk for developing breast cancer. Across the board, African-American women have lower rates of breast cancer than white women, with the exception of women under 40 years old; many breast cancer activists suggest this may have something to do with the frequent use of placenta-infused hair products by the younger demographic.

Along with placenta extract, phthalates and parabens also mimic estrogen and disrupt hormones in the body. Parabens are the most widely used preservative in makeup.

“Parabens have been used in cosmetics since the 1930s as a preservative. It’s anti-microbial in nature, so there is a benefit. They’re not just there,” said Linda Katz, a kind-sounding woman who serves as director of the FDA’s Office of Cosmetics and Colors.

Parabens don’t accumulate in the body, but metabolize quickly and pass through the urine, Katz explained. But when it comes to personal-care products, we don’t really know the concentrations of parabens, or how they interact with other endocrine disrupters, or how many carcinogens may be present in the product but aren’t listed on the label, which is slightly disconcerting.

Between 1973 and 1998, breast cancer incidents in the United States increased by more than 40 percent, according to the Breast Cancer Fund. More than half of breast cancer cases in this country can’t be explained by genetic predisposition, diet or reproductive history, so the guilty contributing factors must come from another source. We also know that breast cancer rates are significantly higher in industrialized nations than in less-developed ones. So what gives?

As breast cancer advocates suggest we consider the role of chemical compounds in our surrounding environment and toxins accumulating in our bodies as a possible risk factor, the cosmetics industry proclaims its commitment to finding a cure, distributing pamphlets about early detection, reminding women to have annual mammograms and sponsoring 5-kilometer walks/runs. Prevention is absent from the industry’s conversation.

“It’s appalling that we’re supposed to be passively waiting for a cure when there’s very little discussion about what’s causing all this, and undoubtedly environmental pollutants are part of the problem,” Malkan said. “All these pink flag-waving companies—Estée Lauder, Revlon and Avon—have a responsibility to do what they can to be part of the solution instead of continuing to make excuses to be part of the cause and to ask, ‘What’s our contribution to the toxic load?’”

Meanwhile, American girls begin puberty at an earlier age, by about one or two years, than they did a generation ago. They’re menstruating and developing breasts sooner, which means they’re also being sexualized at younger ages than before. Nowadays, girls wear makeup as a part of youth, not adulthood. A recent survey of almost 6,000 girls aged 7 to 19 found that 63 percent aged 10 and younger reported wearing lipstick.

Last fall, the Campaign for Safe Cosmetics commissioned an independent laboratory to test red lipsticks for lead, a neurotoxin that accumulates in the body. Exposure can cause learning, language and behavioral problems; seizures and brain damage; lowered IQ; anemia; kidney damage; and it has been linked to infertility, miscarriage and delays in the onset of puberty in girls. Pregnant women and children are more vulnerable, along with unborn babies, as lead crosses the placenta and enters the fetal brain.

The lab purchased lipsticks in four different cities from local drug stores, big-box discount chains, high-end cosmetic shops and department stores. Sixty-one percent of 33 brand-name lipsticks contained detectable levels of lead (following this report, the FDA decided to conduct its own test, but the data is not yet available).

None of the guilty lipsticks listed lead on their labels. Although federal law requires that cosmetics sold on a retail basis to consumers declare ingredients on the label, the cosmetic companies didn’t do anything wrong. They didn’t list lead as an ingredient because it’s not one. It’s a byproduct introduced through the use of other commonly used cosmetic materials, such as zinc oxide and titanium dioxide.

Want to know if your lipstick contains lead? Well, good luck. Think the levels must be minuscule at worst? Not so fast. Lipstick and other beauty products sold in this country may contain unlimited amounts of lead. It’s perfectly legal.

Lipstick lobbying
This past June, Teens for Safe Cosmetics unleashed themselves in the halls of the state Capitol in Sacramento. Three determined young women marched up to their representative’s office with one thing on their mind: the passage of Senate Bill 1712, a bill that would have required companies to make lipstick with the lowest possible amount of lead. The bill had already passed the Senate, and the teenagers believed it would sail through to the governor’s desk. How could it not?

Seventeen-year-old Erin Schrode was one of the young women at the Capitol that day. She’s the spokeswoman for Teens for Safe Cosmetics, and has been with the group since its start in 2005. Schrode, a high-school senior, is an actress and a model. She wears makeup every day, but does so in a responsible way, choosing items free of harmful chemicals. At one point during the S.B. 1712 hearings, Schrode was unexpectedly called up to testify before the Assembly.

“I looked those people right in the eyes and told them that this is one step they could take to protect the future generation,” Schrode said.

The conversation with Schrode reminded me of my first and only lobbying experience in Washington, D.C. I have absolutely no idea what piece of legislation my small group of comrades was riled up about. But I remember our excitement. We had so much of it. Of course, our representatives were too busy to speak with us, but at least we voiced our opinions to their legislative aides.

Unfortunately, sometimes our voices are too small.

A few days after Schrode’s visit to the Capitol, S.B. 1712 failed by one vote in the Assembly Health Committee.

“Honestly, I was shocked,” Schrode said. “It seemed like such a simple step to take. I don’t want to sound naive, but I don’t think the government’s stepping up to the plate in the way they should. Every single lipstick can be reformulated without lead.”

The industry came out in full force to oppose the legislation. Proctor & Gamble sent lobbyists, along with Estée Lauder. Even Johnson & Johnson—a company that doesn’t sell lipstick—made its presence known. This pack mentality protects the industry, although it may frustrate the rest of us.

“I don’t understand how they’re paid to defend toxic chemicals for a living,” said Malkan, who also traveled to Sacramento. “They’re nice people for the most part. They really believe their definition of ‘safe’ is right.”

In terms of safety, here’s the problem: Cosmetics, unlike food and pharmaceuticals, aren’t subject to FDA pre-market approval. So who’s tasked with substantiating the safety of ingredients in products prior to the time we consumers rub and spray the stuff all over our bodies?

Well, that would be the cosmetic firms.

You heard right: This massive $250 billion industry polices itself. Additionally, cosmetic manufacturers aren’t required to file data on ingredients or report cosmetic-related injuries to the federal government. Congress doesn’t authorize the FDA to require recalls of cosmetics, although the agency may request them. From January 2001 to May 2008, the industry recalled 49 cosmetic products, according to Katz. Products with untested ingredients must print the following warning label: “Warning—The safety of this product has not been determined.”

To learn more about the industry’s approach to ensuring public safety, I submitted an online question to Revlon, asking if the company’s New Complexion Oil-Free Powder contained phthalates. The response: “We do not use phthalates as an ingredient in any of our products. Certain of our products that include a fragrance may have phthalates present in minimal amounts as a component of the fragrance as phthalates are sometimes used by fragrance suppliers in formulating fragrances.” (Is it just me or does that statement contradict itself?)

Yes, it’s true. Companies are allowed to keep the ingredients of a fragrance secret, which means when you see the word “fragrance” or “perfume” on a bottle, two, five, nine or even more chemicals may exist in that product in addition to the ones listed on the label. Revlon’s response continued: “You should know that phthalates are present in many products used daily such as food packaging materials and medical devices and that there is no reliable evidence that phthalates are harmful to humans.” (This argument was echoed by Procter & Gamble in its response).

The e-mail noted that the FDA examined phthalates and found their continued use to be safe. But according to the FDA’s Web site, the agency “reviewed the safety and toxicity data for phthalates” including Centers for Disease Control and Prevention data and Cosmetic Ingredient Review panel data, determining that there was insufficient evidence to take regulatory action. But while the FDA conducted laboratory surveys, it has not completed its own toxicology testing.

In its response, Revlon describes the Cosmetic Ingredient Review panel as “an independent scientific panel.” In case you’re interested, the CIR is a group of seven voting members tasked with reviewing the safety of cosmetic ingredients. The CIR office resides in what happens to be the headquarters of the Cosmetic, Toiletry and Fragrance Association. The CTFA—which recently renamed itself the Personal Care Products Council—is the industry’s trade association. And this group funds the CIR.

Incidentally, remember Health Care Without Harm’s campaign to phase out medical devices with polyvinyl chloride from hospitals? That effort was largely opposed by the Advanced Medical Technology Association. A woman named Pamela Bailey headed up the group during that time. She’s now president and CEO of the Personal Care Products Council. What a small world.

The FDA’s Katz sits on CIR’s panel as a nonvoting member. She told me that she mainly listens, but if asked, she’ll offer the FDA’s position or suggest the panel test particular ingredients for safety. “I won’t interfere with the process,” she said. Katz believes the CIR and cosmetics industry “are doing what is appropriate” to ensure cosmetic safety, but she also said, “Do I feel the FDA is still needed to make sure the process runs smoothly? Yes, I do.”

On its Web site, the CIR lists 796 cosmetic ingredients identified “safe as used,” and nine as “unsafe.” The term “safe as used” depends on ingredient concentration and type of product (whether the item is left on and absorbed through the skin or washed off). According to Katz, the CIR has reviewed 1,350 ingredients and expects to have 1,500 completed by the end of this year. When asked how many ingredients exist in cosmetic products—to gauge the significance of these numbers—Katz responded, “I don’t want to go there,” and advised me to check the CIR or Personal Care Products Council Web site.

I called the CIR instead, and spoke with director Alan Andersen. He put the number of ingredients assessed at 1,320. This time when I asked how many ingredients exist in beauty products sold in the United States altogether, I received a response: about 5,700. But only 1,320 of these ingredients have been assessed in the CIR’s 32 years of existence? Seriously?

Andersen acknowledged that the safety-assessment process has been slow, but said the CIR is expanding the program and speeding up the process by hiring new staff, reducing the public-comment period to 60 days and adding two chemists to the panel.

“It’s expertise we felt is needed as we move forward,” Andersen said of the chemists. The panel breaks itself into two teams with the chair overseeing both groups. Each team looks at the same ingredient data to make sure the panel doesn’t miss anything when determining safety. Andersen said the panel and FDA have an effective relationship, one in which the FDA has “tremendous input” into the process.

For instance, in June, the FDA proposed that the CIR undertake a safety assessment of a chemical called chlorphenesin, a muscle relaxant that can cause respiratory problems, vomiting and diarrhea in infants. The chemical is used in pharmaceuticals, but apparently has also been finding its way into personal-care products, specifically nipple cream for nursing mothers, and “they weren’t comfortable with that,” Andersen said. “When the FDA makes suggestions, it gets done.”

Waiting for science
Meanwhile, science continues to throw us curveballs.

In December, a UC Davis study showed that a common antibacterial chemical known as triclocarban added to bath soaps, body washes, cleansing lotions and detergents can alter hormonal activity in rats and in human cells in the laboratory.

“I’m not saying it’s dangerous or worrisome, just that it’s interesting,” said Bill Lasley, a professor emeritus of veterinary medicine and expert of reproductive toxicology at UC Davis, who co-authored the study. I met up with him in his office, where he clarified the science for me with drawings on a whiteboard.

In the early 1990s, he explained, scientists found groups of molecules called “endocrine disruptors,” which upset the steroid process by mimicking and changing cell function. The UC Davis study, however, shows a new type of endocrine disrupter, one that causes augmentation, acting as a stimulant rather than repressor, causing the amount of gene expression that steroid hormones ordinarily cause to develop more rapidly and aggressively. Triclocarban causes increased cell division, something often linked to the development of some forms of cancer. So why not just warn of danger?

“Because we don’t know,” Lasley said. “It would be easy to be an alarmist and talk about the potential and the potential is there.”

He believes, though, the discovery could eventually explain some big pathologies we don’t have answers to, such as prostate cancer, breast cancer and early breast development.

“This stuff has been around for more than 30 years and if it was so terrible to cause alarm we would have known it by now. If it has an effect, it is subtle, incipient and slow-moving,” he said.

But how come it took science so long to find something that’s been in soap for decades? Lasley acknowledged that scientists had been trapped by their own assumptions—looking solely for chemicals that blocked hormone action because that’s what they expected to find.

Products containing triclocarban have been available in this country for more than 45 years, and an estimated 1 million pounds are imported annually. But triclocarban doesn’t have to be used in bath soap and can be easily replaced with a safer alternative, Lasley said.

This is precisely what frustrates Malkan. Over the past few years, manufacturers of personal-care products reformulated some of their products for the European market, removing phthalates banned overseas. Yes, it’s a separate manufacturing stream and switching would require upfront costs, but we’re talking about a $250 billion global industry here.

“I’ve thought about that a lot,” Malkan said. “It’s easier to keep doing things the way they’ve been doing them.”

But the way we’ve been doing things has not been working. We have chemicals in our bodies. That’s not even the question.

Chemicals enter our bodies through beauty products, but also from the environment around us. We sip from water bottles leaching polyvinyl chloride and eat food from metal containers leaching bisphenol A. We put on condoms or insert diaphragms with alkylphenols, bathe enclosed in shower curtains with phthalates and turn on computers that emit polybrominated diphenyl ethers. We drink tap water laced with pharmaceuticals.

The U.S. Toxic Substances Control Act lists about 75,000 chemicals currently in use. Our country produces or imports 42 billion pounds of chemicals daily, and global production is expected to double every 25 years. But when determining the “safety” of beauty products, the federal government fails to consider this larger context.

This isn’t necessarily the FDA’s fault. For the FDA to regulate the personal-care products industry more stringently, Congress must change the law to grant the agency greater authority over cosmetics. Additionally, our government operates under a “prove harm” approach, in which a cause-and-effect relationship between a chemical and harm must be proven beyond a shadow of a doubt to necessitate regulatory action. The European Union, on the other hand, takes a precautionary approach, responding to early warning signs of harm.

So instead of preventing harm like our friends overseas, we wait. We wait for science to give us all the answers, something it may be inadequate to do. We wait for our sisters to be diagnosed with breast cancer and our fathers with prostate cancer. We wait for Congress to grant more funding and authority to the agencies tasked with protecting the common good so they can actually fulfill their responsibility to the American public. We wait for the day when outer “beauty” for women and girls means natural and real and healthy. And all the while, we wait for the beauty industry to clean up its act.

But we may not have to wait much longer. The European Union, under its REACH law (Registration, Evaluation, Authorization and Restriction of Chemicals), requires manufacturers to gather information on the properties of their chemical substances and register the data in a central database; companies must phase out the most harmful chemicals. Last month, Congress passed a bill to ban phthalates and lead from children’s toys—a major step forward for consumer safety. Consumers can also access the Environmental Working Group’s online Skin Deep database, which monitors ingredients found in more than 25,000 personal-care products.

So wake up, chemical industry: The rules of the game are changing, especially if California has anything to say about the matter.

This March, the Organic Consumers Association released a report that found almost 50 percent of personal-care products labeled “organic” or “natural” contained 1,4-dioxane, the byproduct of a petrochemical process called ethoxylation. 1,4-dioxane is a known animal carcinogen and a probable human carcinogen, according to the EPA. Following this report, California Attorney General Jerry Brown filed a lawsuit against manufacturers who failed to provide a warning about 1,4-dioxane in their products, as required by the state’s Proposition 65: The Safe Drinking Water and Toxic Enforcement Act.

Then there’s Senate Bill 484, the California Safe Cosmetics Act. With the passage of the legislation in 2005, California became the first state in the nation to regulate toxic ingredients in cosmetics. The state also established the California Environmental Contaminant Biomonitoring Program to collect information about toxins and requires companies to disclose information about any ingredients identified as causing cancer or birth defects. While disclosure may not seem like much—companies remain allowed to sell products containing ingredients that haven’t been tested for safety—the information obtained will eventually be posted online, available to the public.

“It’s a revolutionary step in the obvious direction,” Malkan said.
The body beautiful
Our heavy reliance on synthetic chemicals is costing us. A recent report commissioned by the California EPA found that chemical and pollution-related diseases in California cost us an estimated $2.6 billion in direct and indirect costs. The report blames inadequate public policies regulating the production and use of hazardous chemicals and suggests a solution: the development of nontoxic, nonpolluting technologies. California’s Green Chemistry Initiative will get us there, as it promotes the development and subsequent use of hazardous-free chemicals that readily break down into innocuous substances in the environment.

Meanwhile, almost 1,000 companies have signed the Compact for Safe Cosmetics, pledging to be free of chemicals known or strongly suspected of causing cancer, mutation or birth defects. Popular brands Tom’s of Maine, Dr. Bronner’s, The Body Shop and Kiss My Face signed the compact. No major brands have signed on, though, meaning the number represents a small share of the market. But it reflects the rumbles of an exploding movement.

“People are starting to question what corporations are telling them and how much power they have,” Malkan said. “But it needs to happen fast, because it seems to be a race to the end. Is consciousness going to raise quickly enough to save us? The younger generation understands this in a way that wasn’t apparent to me at that age.”

Third-wave feminists, like those who make up Teens for Safe Cosmetics, are leading the charge, rewriting a construction of American femininity that defines beauty as the application of a dozen chemical products a day and hundreds of dollars spent on makeup.

Last week, I visited the Sacramento Natural Foods Co-op, searching for toxic-free personal-care items. I decided to pare down my daily regime to the basics; I didn’t need to use so much of that dumb crap in the first place. And as much as it pained me—all that money I’d spent—when I got home, I chucked the other chemical-laden items in my cabinet.

“The industry has so much power over our sense of self and our public space and our health,” Malkan said that one morning in Berkeley. “But the real story is that we have the power to choose what companies we buy from and what we put on our bodies.”

I believe that’s what we call empowerment. And it’s beautiful.

Study: Beauty Obsession More Toxic Than Ever

Tuesday, February 24th, 2009

Hungry fashion models, sexed-up tweens and 50-year-old actresses with baby-plump faces. Today’s pursuit of beauty ideals is an all-too-familiar narrative steeped in medical wizardry, sexual objectification and sheer self-deprivation.

And according to a report published recently by the YWCA, our ceaseless pursuit of perfection is more toxic than ever to American women and girls.

“Beauty at Any Cost,” a lambaste of the beauty and fashion industries, details the emotional and financial dangers of pursuing unrealistic beauty standards. The statistics, compiled from various sources, are worrisome — if not altogether shocking. Some highlights:

•Eighty percent of women say they’re unhappy with their appearance, and 67 percent of women ages 25 to 45 are trying to shed pounds — though 53 percent of them are already at a healthy weight. The report also cited a study in which 69 percent of the respondents (18 and older) said they were in favor of plastic surgery, a 7 percent increase from 2006.

•Forty percent of newly diagnosed cases of eating disorders are in girls 15 to 19 years old, but symptoms can occur as early as kindergarten. Girls who spent the most time and effort on their appearance suffered “the greatest loss of confidence.”

•With the media playing a larger role in our daily lives, young girls are more susceptible to low self-esteem — based on beauty ideals — than ever before and are subject to greater harassment.

“The use of aggressive bullying between girls has been on the rise since the early 1990s, based on issues such as physical attributes and social status,” states one study. According to another: “Mean girls … often don’t grow out of the behavior, and they become adult women who exhibit the same behavior.” And we thought trash-talking on the basketball court was bad.

•Americans fork over nearly $7 billion a year on cosmetics, beauty supplies and fragrance, and nearly 11.7 million cosmetic surgical and nonsurgical procedures were performed in 2007, an almost 500 percent increase in such procedures from 1997. One of the many factoids in the report noted that if women put the average amount of money they spent on monthly manicure-pedicures ($50) into an interest-bearing retirement account every year for 10 years, they would have almost $10,000 saved. Easier said than done.

“We felt the problem had reached such a crisis proportion that we needed to speak up and draw a line in the sand that this must stop,” said Nancy Loving, director of communications for YWCA U.S.A., who added that the group will use the report as a jumping-off point for educational programs in its 300 locations in the U.S.

“If you’re constantly made to feel inadequate, you’re really quite disabled in terms of being able to achieve in other areas of life: academic, social and political.”

Getting a Monthly dose of Poison with your Tampons

Tuesday, February 24th, 2009
Note: Canary Cosmetics carries Natracare Tampons. 
Every month millions of women everywhere depend on a little helper to do it’s job but how many of us realize we are taking a little dose of poison at the same time. The rise of female diseases and compromised immune systems of our multi generational female population encourages a closer look at this dependable and consistent consumer choice.

Ninety nine percent of the conventional tampons marketed to women are a rayon fiber and or cotton combination of fibers that have been chlorine bleached. Rayon fibers are made from chemically processed wood pulp in a process that wastes almost two thirds of the wood material. The cotton used in conjunction with the rayon fibers have been bleached in chlorine. Chlorine leaches a chemical by-product known as “dioxins” which are powerful carcinogens that can damage the immune system and disrupt the endocrine system. Hundreds of studies have shown a direct link between dioxin exposure and cancer, birth defects and reproductive disorders.

When was the last time you looked at the ingredients on your tampon box? Here are the usual ingredients listed: Rayon and/or Cotton Fiber, Polyethylene/Polyester, Polyester or Cotton, Polysorbate 20, Fragrance. Anytime you see “Fragrance” in the ingredient list…buyer beware! When there is not a direct and conclusive list of the fragrance source such as “organic rose or lavender oil” you are unconsciously subscribing to phthalates. Phthalates are industrial chemicals frequently added to consumer products to make fragrances last longer and to make plastic more flexible. Phthalates are found in shower curtains (a recent pull from all major stores), makeup, nail polish and in our bodies via a “blood burden” test. Phthalates are suspected hormone disruptors that can enter the human body via skin absorption, inhalation and ingestion.

We Americans have been desensitized to what smells, feels and tastes good to us. We have forgotten what “squeaky” clean means through a number of masked and very well thought out marketing campaigns to make us “think” we know what smells, feels and tastes good. Currently there are only two companies that are creating 100% organic cotton tampons that have not been bleached with chlorine. Natracare and Seventh Generation make tampons with or without applicators that are clean and green enough to use anywhere in or on your body. Shouldn’t that be the idea? Their websites are www.natracare.com and www.seventhgen.com

I encourage you to try them out and see if you can feel the difference! You may spend a few pennies more each month but on the flip side you won’t be spending hours of your precious life in compromise. It is a completely different feeling having something inside of you that isn’t compromised and drenched in chemicals.

Sun damage may exacerbate skin penetration of nano-sunscreens

Tuesday, February 24th, 2009
Nanoparticles may penetrate sun damaged skin causing concern about their increasingly widespread use in sunscreens, according to new research.

In a paper published in Nano Letters, scientists at the University of Rochester found that quantum dot nanoparticles penetrated UV damaged skin more than non-compromised skin.

The conclusion was reached from in-vivo tests carried out on mice exposed to UV light levels similar to those that would induce medium level sunburn in humans.

Gauging the impact of sun damage

To gauge the impact of sun damage on the penetrative capabilities of nano-based sunscreens the scientists used quantum dot nanoparticles.

These are not generally used in sunscreens despite their UV absorption properties but they are a similar size to the titanium dioxide nanoparticles used commonly in sunscreens.

The authors of the study said the higher penetration levels observed in sunburned skin led them to the conclusion that the condition of the skin strongly influences penetration.

Important discovery

“This is an important discovery for nanoparticle safety concerns as consumers often apply sunscreens containing metal oxide nanoparticles of similar size and raw material properties to UV-exposed skin,” said the authors.

They said direct comparisons were impossible to make at this stage as a wide variety of surface coatings are used in commercial sunscreens that may alter skin penetration characteristics.

The authors called for further research. “Future in-vivo studies using custom imaging modalities and commercial sunscreen formulations are planned to generate the necessary insight to assess human health risks from applying nanoparticle sunscreens to UV-damaged skin.”

Nanotechnology: It’s a small, small world

Tuesday, February 24th, 2009

Note: Canary Cosmetics does not use nanoparticles in our products.

August 5, 2008

When Andrew Taton slathers sunscreen on his toddler he knows he’s protecting her from the sun’s rays, but he’s also aware of an invisible magic in sunscreen: nano particles. 

Zinc oxide and titanium dioxide, which put the “screen” in sunscreen, used to leave a white film. Now they’ve been nanosized, made so small that they’re invisible. “They’re really very super small particles,” explained Taton, a chemistry professor at the University of Minnesota who specializes in nanoparticles.

But he’s not completely comfortable with the magic. “I’m a scientist, and I have to issue a cautionary note,” he said. “Science doesn’t really know if they stay on the skin.”

Sunscreen isn’t the only product using nanotechnology. It’s in Behr brand paint at Home Depot, Nano-Tex sheets sold at J.C. Penney, stain-resistant pants from L.L. Bean, the First Response pregnancy test from Walgreens. Even the Metrodome beer hawker is selling nanotechnology in the plastic bottles.

Surprised? You’re not alone. Polls show that most Americans have no idea how far this new realm of science and engineering has reached into their lives.

Indeed, some 600 consumer products now contain nanoparticles, according to Project on Emerging Nanotechnologies in Washington, D.C., which maintains an inventory of consumer products using nanomaterials (www.nanotechproject.org/inventories/consumer). Two to three are added daily, according to director David Rejeski — but that’s only a guess. Manufacturers don’t have to disclose the use of nanotechnology.

Why are nanoparticles in stores?

Thousands of times smaller than the width of a human hair, roughly 1 to 100 nanometers in dimension, nanoparticles occur naturally in the environment, such as the very minute particles in smoke.

What is new is that we can now create and manipulate them, change their atoms around, make different shapes and sizes. And that’s where the magic lies. Carbon, for instance, becomes as light as plastic but many times stronger than steel; aluminum becomes explosive. 

Apply these new materials to consumer goods and your socks don’t stink (nanosilver), liquids roll right off your trousers (tiny whiskers in cotton) and the urine dipstick changes color if you’re pregnant (nano- gold). Thousands of transistors will fit in the space of a hair, making for powerful microelectronic devices. With the right nano-coating, guitar strings last longer and squeak less. Hockey sticks, golf clubs and tennis rackets are lighter yet stronger.

Consumer products are a natural — and lucrative — outlet for nanotechnology, but it doesn’t stop there.

Nanotechnologies can deliver medicine precisely where needed in cutting-edge chemotherapy. MIT’s Institute for Soldier Nanotechnology is creating a battlefield suit that, among other things, detects and neutralizes chemical and biological agents. Nokia’s Morph concept is a cell phone that’s rigid one moment and flexible the next, so it can be worn around your wrist.

There isn’t an aspect of living that won’t be affected by nanotechnology, experts predict.

The dark side

Despite the opportunities and promise of nanoscience, many scientists and environmentalists are sounding the alarm.

“We don’t know nearly enough about the adverse reactions to any of these materials, environmental or biological,” said J. Clarence Davies, a former Environmental Protection Agency official and one of the nation’s foremost authorities on environmental regulation and policy.

It was recently discovered, for example, that when some nano-sized carbon material enters the lungs, it acts like asbestos, creating tissue and cell scarring that scientists say could lead to cancer. And some materials go where they’re not supposed to. A University of Rochester, N.Y., study found that when rats inhaled nanoparticles, instead of lodging in the nose or lung as expected, the particles also made their way to the rats’ brains.

In sunscreens, nanoparticles have been used for the past decade or so, and they’re generally believed to be safe. Some watchdog groups, such as the Environmental Working Group, prefer them over sunscreens containing other chemicals such as oxybenzone. They appear to stay on the skin — unless there’s a cut or abrasion, noted Christy Haynes, who is researching nanoparticle toxicology at the University of Minnesota. 

If that happens, “nobody has a good answer to where they go in your body and what happens when they’re there,” she said.

More research needed

Then there’s the environmental question. One study shows manufactured nanoparticles in nature could be trouble. A University of Montreal study found nanoparticles of cadmium in shellfish, which caused reproductive and digestive problems.

The silver nanoparticles in socks and lining the inside of some washing machines do a good job of killing bacteria, but they apparently don’t stay there. They wash out and enter the wastewater, where they kill beneficial bacteria needed to treat wastewater. The U.S. Environmental Protection Agency (EPA) has been asked to classify these products as pesticides, requiring that they be registered.

What is needed now, Davies says, is more research and oversight.

“Sometimes we want nanomaterial to be toxic, like when it’s used in chemotherapy,” said Haynes, who is working on studies to develop toxicity guidelines. “But we don’t want toxic side effects in nanomaterials that are repelling stains.”

Davies hopes the next administration in Washington will fund research and regulation to ensure health and safety for consumers, workers and to protect the nanotechnology industry.

Nanotechnology has incredible potential to cure disease, increase communication and even solve pollution problems and energy dilemmas. But it’s important to find out about problem materials before and not after widespread application, Davies said.

“The future of nanotechnology is unimaginable; science fiction looks pale in comparison,” he said. “We just need to do it right.”

Is your makeup killing you?

U.S. lax on banning ingredients that could be harmful to humans
By Maggie Downs • The Desert Sun • July 26, 2008

What’s in your makeup bag might not be so pretty.

Many of us scan the labels on our food to determine what’s healthy and what’s not.
Yet every day, we use multiple health and beauty products — from toothpaste to deodorant to hair spray — that are inhaled, absorbed through the skin or ingested. If you read the labels at all, they’re difficult to understand, filled with tiny type and hard-to-pronounce words.

But don’t be so quick to dismiss those ingredients.

Personal care products like shampoo, conditioner, lotion and makeup are not regulated by the Food and Drug Administration — or any other government agency.

“Manufacturers may use any ingredient or raw material, except for color additives and a few prohibited substances, to market a product without a government review or approval,” says a statement on the FDA’s Web site.

The European Union has banned more than 1,100 chemicals from cosmetic products. In contrast, the United States has banned 10, according to the Campaign for Safe Cosmetics.

For instance, it is currently legal in the United States for lipstick and other beauty products to contain unlimited amounts of lead. A ban to remove lead in lipsticks was defeated last month in California.

However, there is hope on the horizon.

Many consumers now recognize what you put on your body is just as important as what goes in it — and that is leading companies to follow suit.

The health and beauty aisles at major chains are slowly being taken over by healthier products.

For example, drugstore giant CVS announced in May the company will remove chemicals linked to adverse health outcomes from its house-branded products. They will replace them with safer alternatives.

If you’re wary of using beauty products with industrial ingredients, here are some items to avoid:

Lead and mercury: Lead is found in hair dyes and makeup. It is a toxin for the brain and nervous system and can cause infertility or miscarriage.

Mercury is found as a preservative in eye cosmetics. It is a toxin for the nervous system.

Parabens: Found in shampoos, commercial moisturizers, shaving gels, cleansing gels, personal lubricants, topical pharmaceuticals and toothpaste, parabens have been found in tissue samples from human breast tumors, according to one study.

Parabens come in many types, including methyl-, ethyl-, propyl-, butyl-, isobutyl- and others and can mimic estrogen.

Phthalates: Found in fragrances, hair products, deodorants, lotions and much more, this chemical plastic has caused birth defects in lab animals.

Phthalates are often listed under the term “fragrance” on labels, so select fragrance-free products.

Petrochemicals: Found in anti-aging creams, lipsticks, baby creams, eye shadows, mascara, perfume, lip balm and more. Listed as petrolatum, paraffin and mineral oil, these products can cause allergic reactions and contain suspected carcinogens.

Placenta: Found in hair relaxers, moisturizers and toners. Placenta produces hormones that can disrupt the body’s normal hormone production and lead to serious problems.

Nanoparticles: Found in sunscreens, eye shadows, bronzers and lotions. These are extremely small particles that can be absorbed directly into the bloodstream and have not been tested for safety.

Diethanolamine (DEA): Used in shampoos, DEA is a suspected carcinogen. Also look for triethanolamine (TEA), which can be contaminated with nitrosamines, compounds shown to cause cancer in laboratory animals. Contamination is more likely if the product also contains Bronopol.

Formaldehyde: Found in eye makeup, mascara and other cosmetics, formaldehyde is classified as a probable human carcinogen.

In its liquid state, look for it listed as DMDM hydantoin, diazolidinyl urea and quaternium-15, which can be absorbed through the skin and nails.

Bronopol, often listed as 2-bromo-2-nitropropane-1,3-diol, can contribute to the formation of cancer.

Glycol Ethers: Found in nail polish, deodorant, fragrances and other cosmetics, some glycol ethers are hazardous to the reproductive system and can cause irritation of the skin, eyes, nose and throat.

Avoid EGPE, EGME, EGEE, DEGBE, PGME, DPGME and those with “methyl” in their names.

Phenylenediamine (PPD): Found in hair dye, this is also called oxidation dyes, amino dyes, para dyes or peroxide dyes. PPD has been banned in Europe as a carcinogen.

Toluene: Found in nail polish. Can cause liver damage and irritate the respiratory tract.

Class action over lead in lipstick

Sunday, August 31st, 2008

http://www.news-medical.net/?id=40114

Class action against a top manufacturer of women’s perfumes and makeup has been given the green light to proceed in the United States.

The legal action is against the major luxury goods company giant LVMH and concerns lipstick produced for Dior which has been found to contain unacceptably high levels of lead.

Dior’s Addict Positive Red lipstick apparently contains double the safe level of lead and is at the centre of the case but is by no means the only  culprit.

The high lead levels were revealed following scientific investigations in October last year on behalf of the U.S. consumer group The Campaign for Safe  Cosmetics which tested 33 brand-name lipsticks and found two-thirds  contained detectable levels of lead; of those, half were above the lead  limit for lead in candy. The Campaign for Safe Cosmetics says lead is a potent neurotoxin and is  linked to numerous health and reproductive problems and does not belong in  lipstick.

A call by LVMH that the lawsuit filed against it in November be thrown out, has been rejected by a Chicago court, which now allows the case to proceed.

Exposure to lead can cause learning and behavioural problems and is linked to infertility and miscarriage; it has also been linked to kidney damage;  pregnant women and young children are particularly vulnerable - lengthy  exposure can be fatal.

The Campaign for Safe Cosmetics says many in the beauty industry are reluctant to change their practice even though some are already making  lead-free lipstick and also says the U.S. Food and Drug Administration (FDA)  has been slow to advise the public.

Health Canada has also released a study of lead in lipstick, where 21 out of 26 lipsticks tested contained lead ranging from .07 to .84 ppm and one  product contained an alarmingly high lead level of 6.3 ppm.

The Campaign for Safe Cosmetics, which is a coalition of public health, environmental and women’s groups says it is possible to make lipsticks  without lead, and all companies should be doing that.

The Cosmetic, Toiletry and Fragrance Association trade group says that lead is a naturally occurring element that was not intentionally added to  cosmetics.

Two other class actions in the U.S. are also in the pipeline, against L’Oreal and Proctor & Gamble, the manufacturers of Covergirl cosmetics.

It is currently legal in the United States for lipstick and other beauty products to contain unlimited amounts of lead, while in Australia, it is  mandatory for cosmetics to list all ingredients on their labels and for  cosmetics containing lead to carry warning statements and safety directions.

A skin-deep dilemma: Sunscreen

Saturday, August 30th, 2008

http://www.denverpost.com/news/ci_9746754?source=pop_section_news&_requestid=7058400
 
Is sunscreen essential body armor against cancer and aging? Or is it another assault on your skin? Here’s how to know what’s tops in the tube.

By Vicky Uhland
Special to The Denver Post

There was a time, not all that long ago, when the sun was fun and all you had to know about sunscreen was which one would make you more Baywatchable: the coconut-scented oil or the coconut-scented lotion?

Now we know the sun is full of death rays, and sunscreens are our body armor. Everyone from the Food and Drug Administration to the mom next door will tell you that if you go outside without a thick coating of white goo, you risk premature demise from skin cancer.

So you’ve adjusted your fun-in-the-sun routine to include slathering yourself in a protective layer of sunscreen.

But wait: New research has put a few chinks in that armor. Some clinical studies suggest sunscreens do not prevent basal-cell carcinoma and may not reduce the risk of developing the rarer, but more deadly, skin cancer melanoma.

Worse yet, the Environmental Working Group, a nonprofit consumer watchdog agency, found in a 2007 study of nearly 1,100 sunscreens that 87 percent either don’t adequately protect you from the sun or have ingredients with significant safety concerns.

Short of spending your life in a darkened room like some character in a Tennessee Williams tale, is it possible to enjoy your summer days without fear of cancer or harmful sunscreen ingredients? Sure, if you keep the following tips in mind.

SLIP, SLOP, SLAP.

Australians came up with this slogan that encourages people to slip on a shirt, slop on some sunscreen and slap on a hat. Health agencies report that people rely too much on sunscreen when there are other forms of protection available.

But be careful what type of clothing you choose. According to the Skin Cancer Foundation, a long-sleeved, white cotton T-shirt’s ultraviolet-protection factor is 7, whereas a long-sleeved dark denim shirt’s is 1,700, which amounts to a complete sunblock. A UPF of 15 or higher is considered sun-protective.

This doesn’t mean you have to wear a jean jacket when it’s 95 degrees. Unbleached cotton has a pigment that absorbs the sun’s ultraviolet rays, and silk or polyester with a sheen reflects rays, according to the Skin Cancer Foundation. You can also wash your clothes in SunGuard, a product from Rit dye that contains a built-in sunscreen.

KNOW YOUR CHEMICALS.

Sunscreens are regulated by the FDA, which allows only 17 active ingredients. Two of these are minerals — titanium dioxide and zinc oxide — which work by reflecting and scattering the sun’s rays away from your body. The rest are chemicals, which absorb the sun’s rays and keep them from causing damage.

According to the Environmental Working Group, not all these chemicals are created equal. The group analyzed nearly 400 studies and 60 government, academic and industry databases before issuing its report on sunscreens last summer. It found numerous studies showing that the most common sunscreen chemical, octinoxate, can act like estrogen in the body, increasing the risk of breast cancer and uterine damage.

But octinoxate is not as bad as oxybenzone, the second-most common sunscreen chemical, or PABA or its derivative, padimate O. Both of these ingredients may damage cells, disrupt hormones and cause allergic reactions, according to a variety of studies.

The least harmful active ingredients in sunscreens include titanium dioxide, zinc oxide and avobenzone, according to the Environmental Working Group.

Check out the group’s rankings at cosmeticsdatabase.com. You can type in the name of your sunscreen, scroll down and see how it ranks in terms of sun protection and potential chemical danger.

LEARN YOUR SUNSCREEN ALPHABET.

Sunscreens are rated by SPF, or sun protection factor, but that only tells half the story. According to the FDA, SPF measures the damage from UVB rays — the ones that cause sunburn. There is no measurement for UVA rays, which penetrate deeply into the skin, creating wrinkles. Both types of rays may cause skin cancer.

The FDA is considering a new sunscreen rule that would rate UVA protection using a system of stars, but that rule has been in the works for more than a year, and no implementation date has been set.

In the meantime, how can you tell if your sunscreen blocks UVA rays? Look for labels that say “broad spectrum,” or check the ingredients list for the four FDA-approved UVA blockers: titanium dioxide, zinc oxide, avobenzone (also known as Parsol 1789) and mexoryl.

SPF measures how long you can stay in the sun without burning. If you normally burn in 10 minutes, a sunscreen with a 15 SPF would protect you 15 times as long, or 150 minutes, assuming you don’t sweat or get wet. But that equation changes at 30 SPF. A sunscreen with an SPF of 50 blocks only about 1.3 percent more UVB rays than an SPF 30, according to the Environmental Working Group.

Even if the SPF promises a full-day frolic in the sun, the American Cancer Society recommends reapplying sunscreen every two hours or immediately after swimming or sweating heavily. The environmental group says water-resistant sunscreens buy you an extra 40 minutes after swimming, and “very water resistant” allows you to wait 80 minutes before slopping on more sunscreen.

NO-NO NANOS?

With their ability to block UVA rays and a lack of harmful chemicals, titanium dioxide and zinc oxide seem like wonder ingredients. But these sunblockers have a downside: They turn your skin clown white.

To get around this, many sunscreen makers either nanoize or micronize the minerals, which makes them so small they virtually disappear on the skin. Nanoparticles are defined as anything 100 nanometers or smaller; one nanometer is one-billionth of a meter. Micronized minerals are generally between 100 and 1,000 nanometers.

If nanoparticles penetrate the skin, research shows that they can create serious havoc, causing DNA damage and even killing cells. But the Environmental Working Group analyzed 15 studies on nanoparticles and found that nearly all showed no absorption of nanoized zinc oxide and titanium dioxide sunscreen ingredients through healthy skin.

Be careful, however, if you have scraped, sunburned, acne-prone or otherwise damaged skin, the group warns. Researchers also aren’t sure how nanos in sunscreens affect those with thinner skin, such as children or the elderly.

Although the FDA is considering regulating nanos in sunscreens, there is no way to tell whether your favorite brand has them. The nonprofit group Friends of the Earth lists some at foe.org/nano_sunscreens_guide/Nano_Sunscreens.pdf. A caveat about this document, though: Some products that do not use nanoparticles, such as Lavera’s German-made, nano-free, SPF 15 mineral sunscreen, are lumped into the caution category and labeled “Products may contain manufactured nanoparticles. Retailer will not provide information.”

Micronized minerals so far have escaped the scrutiny associated with nanoparticles and are considered safe sunscreen ingredients. But because they vary so much in size, they may not rub in well. If you don’t want to look Elizabethan, it’s essential to try any mineral sunscreen before you buy.

GO NATURAL?

Such stores as Whole Foods and Vitamin Cottage carry sunscreens that are labeled natural. But like any sunscreen, natural sunscreens have to use one or more of the FDA-approved active ingredients, so you’ll find the same chemicals in Alba Botanica as you will in in Banana Boat. But natural sunscreens may also contain ingredients such as black tea or broccoli extract, which have proven sun-fighting capabilities, and skin soothers like essential oils. They may also use less harsh preservatives.

NANOTECH: THE UNKNOWN RISKS

Saturday, August 30th, 2008

From: Yale Environment 360, Jun. 23, 2008

 

(Note: Canary Cosmetics does not use any nanoparticles in any of its products.) 

 Nanotechnology is booming. But concern is growing that its development is outpacing our understanding of how to use it safely.

 

By Carole Bass

 

“It’s green, it’s clean, it’s never seen — that’s nanotechnology!”

 That exuberant motto, used by an executive at a trade group for nanotech entrepreneurs, reflects the buoyant enthusiasm for nanotechnology in some business and scientific circles.

 

Part of the slogan is indisputably true: nanotechnology — which involves creating and manipulating common substances at the scale of the nanometer, or one billionth of a meter — is invisible to the human eye.  But the rest of the motto is open for debate.

Nanotech does hold clean and green potential, especially for supplying cheap renewable energy and safe drinking water. But nanomaterials also pose possible serious risks to the environment and human health — risks that researchers have barely begun to probe, and regulators have barely begun to regulate.

 What’s more, the potential damage could take years or even decades to surface. So these tiny particles could soon become the next big thing — only to turn into the next big disaster.

Nano enthusiasts see it as the next “platform technology” — one that will, like electricity or micro-computing, change the way we do almost everything. While that prediction is still unproven, there’s no question that nanotech is booming. Universities, industry, and governments around the globe are pouring billions into creating and developing nanoproducts and applications. A range of nanotechnologies is already used in more than 600 consumer products — from electronics to toothpaste — with global sales projected to soar to $2.6 trillion by 2014.

Environmentalists, scientists, and policymakers increasingly worry that nanotech development is outrunning our understanding of how to use it safely. Consider these examples from last month alone:  An animal study from the United Kingdom found that certain carbon nanotubes can cause the same kind of lung damage as asbestos. Carbon nanotubes are among the most widely used nanomaterials.

A coalition of consumer groups petitioned the U.S. Environmental Protection Agency to ban the sale of products that contain germ- killing nanosilver particles, from stuffed animals to clothing, arguing that the silver could harm human health, poison aquatic life, and contribute to the rise of antibiotic resistance.

Researchers in Singapore reported that nanosilver caused severe developmental problems in zebrafish embryos — bolstering worries about what happens when those antimicrobial products, like soap and clothing, leak silver into the waste stream.

The U.S. Department of Defense, in an internal memo, acknowledged that nanomaterials may “present… risks that are different than those for comparable material at a larger scale.” That’s an overarching risk with nanomaterials: Their tiny size and high surface area make them more chemically reactive and cause them to behave in unpredictable ways. So a substance that’s safe at a normal size can become toxic at the nanoscale.

Australian farmers proposed new standards that would exclude nanotechnology from organic products.

The European Union announced that it will require full health and safety testing for carbon and graphite under its strict new chemicals law, known as REACH (for Registration, Evaluation, and Authorisation of Chemical Substances). Carbon and graphite were previously exempt, because they’re considered safe in their normal forms. But the U.K.  study comparing carbon nanotubes to asbestos, along with a similar report from Japan, raised new alarms about these seemingly harmless substances.

Old Materials, New Risks

 The EU’s move is a critical step toward recognizing nanomaterials as a potential new hazard that requires new rules and new information.  The raw materials of nanotechnology are familiar. Carbon, silver, and metals like iron and titanium are among the most common. But at the nanoscale, these well-known substances take on new and unpredictable properties. That’s what makes them so versatile and valuable. It also makes them potentially dangerous in ways that their larger-scale counterparts are not.

Yet governments are only beginning to grapple with those dangers.  Japan’s labor department issued a notice in February requiring measures to protect workers from exposure to nanomaterials: It may be the world’s first nano-specific regulation affecting actual practices.

Previously, Berkeley, California — ever ready to stand alone — had adopted what is apparently the only nano-specific regulation in the United States: a requirement that companies submit toxicology reports about nanomaterials they’re using.

At the federal level, the EPA launched a voluntary reporting program in January; industry participation has been anemic. Both the EPA and the Food and Drug Administration have so far declined to regulate nanomaterials as such, saying they’re covered under existing regulations. The National Institute for Occupational Safety and Health has issued recommendations for handling nanomaterials, but the agency has no enforcement power.

The European Union, by contrast, is taking a precautionary approach.  While U.S. regulators generally presume products to be safe until proven harmful, the EU’s new REACH legislation demands that manufacturers demonstrate the safety of their chemicals. Just last week, the EU released a document concluding that nanorisks “can be dealt with under the current legislative framework,” with some modifications. For example, the document says that under REACH, when companies introduce nanoforms of existing substances, they must provide additional material about “the specific properties, hazards, and risks” of the nanomaterials.

At this point, however, many of the most basic questions about those nanohazards are unanswered. What materials are harmful, in what particle sizes and shapes, under what conditions? Who is at risk:  Workers? People using nano-enabled products? Wildlife and ecosystems?

How should we measure exposures?  The U.S. government spends $1.5 billion a year on nano research. Less than 5 percent of that is aimed at addressing these fundamental questions.

Danger Signs

 What is known about nanohazards counsels caution.  Nanomaterials are so small that they travel easily, both in the body and in the environment. Their tiny size and high surface area give them unusual characteristics: insoluble materials become soluble; nonconductive ones start conducting electricity; harmless substances can become toxic.

Nanoparticles are easily inhaled. They can pass from the lungs into the bloodstream and other organs. They can even slip through the olfactory nerve into the brain, evading the protective blood-brain barrier. It’s not clear whether they penetrate the skin. Once they’re inside the body, it’s not clear how long they remain or what they do.  What’s more, current science has no way of testing for nano-waste in the air or water, and no way of cleaning up such pollution.

The tiny cylinders known as carbon nanotubes, or CNTs, are among the most widely used nanomaterials. These tubes, which come in different sizes and shapes, lend extraordinary strength and lightness to bicycle frames and tennis rackets; researchers are also investigating uses in medicine, electronics and other fields. The recent UK study found that long, straight CNTs, when injected into lab mice, cause scarring even faster than asbestos. One of the investigators predicts the scarring will lead to cancer; other experts are less sure. The study doesn’t prove whether it’s possible to inhale enough CNTs to cause the same results as the injections. But which workers want to serve as the test cases?

Another red flag is silver. Manufacturers are lacing ordinary household objects — from toothpaste to teddy bears — with nanoparticles of silver, long known for its disinfecting powers. A recent experiment on nanosilver-containing socks, touted as odor- eating, found that silver particles leaked out into the wash water.

Once there, the silver could interfere with water-treatment efforts, in part by killing good microbes as well as the nasty ones, and might threaten aquatic life (a fear supported by the zebrafish study).

When Samsung started marketing a washing machine that emits silver ions two years ago, a national association of wastewater treatment authorities asked the U.S. Environmental Protection Agency to regulate such equipment as pesticides. And indeed, EPA has required some manufacturers to register nanosilver-containing products — like computer keyboards — as pesticides or drop their germ-killing claims.

A farm-oriented pesticide law dating to 1947 is scarcely the right tool for addressing the 21st-century hazards of nanotechnology. But it’s the only tool that EPA enforcers have, since the agency’s policymakers have explicitly declined to regulate nanomaterials as such.

What Price Convenience?

 Of the hundreds of nano-enhanced products now on the market, many are cosmetics, and many others, such as clothing and computer peripherals, are spiked with silver for unnecessary antibacterial effects.  Convenience items, like stain-resistant sofas and static-free fleece, are a third big category.

It would be easy to say, “Who needs this stuff? Just wash your hands (or feet, in the case of the smell-resistant socks), clean up your spills and keep the nano magic on the shelf until we know whether it’s safe.” Indeed, some environmental groups are calling for a moratorium on nano-containing products.

But nanotech also has a tremendous upside in medicine — whether for treating cancer or regrowing bones — and in green applications, from affordable solar cells to super-efficient water filtration. In any case, this technology is not going away. The U.S. House of Representatives voted on June 5 to reauthorize the $1.5 billion-a-year National Nanotechnology Initiative; the Senate is expected to act in the coming weeks.

The House bill mandates “a detailed implementation plan for environmental, health, and safety research.” That’s an important step forward, but it’s not enough. As we hurtle into this very small future, we need to pay much more attention to the potentially large risks.
