(CNN) One in 12 beauty and personal care products marketed to African-American women in the US contains highly hazardous ingredients, according to research released Tuesday by the Environmental Working Group , a nonprofit environmental organization in the US specializing in research and advocacy.

The organization analyzed more than 1,100 products marketed to black women -- people who identify as African-American as well as those from the Caribbean and other areas -- and found that less than a quarter scored "low" on its hazard scale.

By contrast, 40% of products that are marketed to the general public are classified as low-risk.

The report said the worst products were hair relaxers, hair colors and bleaching products, which studies have linked to potential health harm.

Ingredients have been tied to hazards including risk of cancer, hormone disruption, developmental and reproductive damage, and allergies.

"If a black woman is choosing products marketed to their demographic, they have fewer healthier options," said Nneka Leiba, deputy director of research at the Environmental Working Group, a Washington-based nonprofit research organization.

For example, "there are formaldehyde releasers in hair dyes," Leiba said. Formaldehyde, a known cancer-causing agent, is present in products across the entire beauty market, but "there are less products without them" for black women, she said.

This analysis is the first to assess products tailored to this demographic for their risks and dangers to consumer health. The products, and their ratings, have been added to the group's Skin Deep database , a searchable database providing information on the safety and potential harms of more than 64,000 cosmetic products.

The idea was to give people a place to go to be informed about the products they're using.

"We saw there was a deficit associated with African-American women," Leiba said, adding that as consumers, this demographic makes up a significant proportion of consumers of personal care products. The report says African-Americans account for as much as 22% of the market for personal care products, but until now, information on the hazards associated with the products they buy was inadequate.

"We received emails asking for products targeting black women" to be included, said Paul Pestano, senior database analyst and co-author of the report. For example, "studies that have been done on relaxers are small studies."

'A very personal choice'

The most recent analysis involved 1,177 products such as deodorants, bar soaps, makeup, hair products, sunscreens and moisturizers -- more than half of the products included were for hair care.

Some men's and baby products were also included, such as baby lotions, styling gels and shaving creams.

None of the hair relaxers, hair colors, bleaching products, lipsticks, concealers, foundations or sun-protective makeup products included in the new analysis were classified as "low hazard" on the Environmental Working Group scale, which runs from 1 (low) to 10 (high) based on factors such as ingredients and evidence base for their harm. Fifteen of the hair relaxers analyzed scored an average of 8.1 on the scale, placing them firmly in the range of products that should be avoided.

The researchers hope the people buying these products will use the findings to use the Skin Deep database to learn about products before buying them.

"What you choose to bring into your home is a very personal choice," Leiba said, adding that the goal is not to dictate what people should and shouldn't buy but to help them perceive their risk. "You can still relax your hair (if you want), but maybe then avoid use of your lipstick if it scores badly."

Since data began to emerge on the risks associated with hair relaxers, many women have veered away from them. But both Leiba and Pestano add that just because a product may label itself as a "natural" alternative, that doesn't mean it is risk-free.

"We don't want people to assume that because they are choosing a natural product that they are not choosing harmful products," Leiba said.

Some relaxers may not contain caustic ingredients, for example, but they may have fragrants or preservatives -- such as parabens -- that can be harmful. Parabens are potential hormone disruptors, their risk increasing with accumulated use.

Some concealers and foundations were also found to have retinyl palmitate, a form of vitamin A that has been linked to skin cancer, according to the group.

Knowing the risks

Most cosmetics and ingredients don't need approval from the US Food and Drug Administration before they go on the market.

Products "must be safe for consumers under labeled or customary conditions of use, and they must be properly labeled," the agency said. "Companies and individuals who manufacture or market cosmetics have a legal responsibility to ensure the safety of their products. However, the law does not require cosmetic companies to share their safety information, including adverse events."

Leiba believes that informed consumers can instead push companies to re-evaluate their products and make them more consumer-friendly.

"This report will help push the companies that make these products marketed to black women," she said. "We want to empower all demographics."

"It's an interesting piece of research which further emphasizes the need for phasing in safer chemical substances in cosmetics, particularly for sub-populations who might be making greater use of problematic compounds," said Paul Whaley, an environmental scientist at the University of Lancaster in the UK, who was not involved with the study.

"It is good to see EWG reinforcing this point; hopefully, this will lead to more research into safer alternatives, acceleration of phase-out of hazardous substances and also closer regulatory scrutiny of what chemicals should be permitted in cosmetics in the first place."

"As highlighted in the study, there is far too little research and far too little known about the ingredients in cosmetics," added Professor Philippa Darbre from the University of Reading. "Ingredients added to cosmetics have received far too little regulatory attention compared with ingredients taken into the body by mouth such as food, drink and pharmaceuticals and this needs to change. Although chemicals applied to the skin are absorbed to a lesser degree than chemicals taken in by mouth or breathed in through the lungs, nevertheless chemicals are absorbed at low levels over long-term usage and as highlighted in the report."

Darbre believes that studies like this raise awareness among consumers and gives them the opportunity to switch to different products. " At the current time, my feeling is that it is best for consumers to cut down (or cut out) on what they use. Reducing overall chemical burden is the best way forward until more information is available."

The beauty industry defended its development process, highlighting the role safety plays when products are approved for consumer use. "Consumer and product safety are top priorities for the cosmetics and personal care products industry, with careful and thorough scientific research and development serving as the foundation for everything we do," Linda Loretz, chief toxicologist at the Personal Care Products Council, said in a statement. The council sponsors its own ingredient database, Cosmeticsinfo.org

"Personal care products companies invest nearly $3 billion each year in scientific research and development. Numerous scientific, peer-reviewed papers are published on evaluating ingredient safety and enhancing or developing new safety methods. Companies take their responsibility for consumer and product safety very seriously."
