Per- and polyfluoroalkyl substances (PFAS) are a group of manufactured chemicals containing ix,000 different compounds that have been around since the 1940s. PFAS do not break down and accumulate in the surround and human body over time. The substances persist for long periods of time, hence the nickname "forever chemicals." They are linked to astringent health effects such as cancer, hormone disruptions, weakened immune systems, and low birth weights. The toxic chemicals are establish in various everyday consumer products, including non-stick cookware, pizza boxes, stain repellants—and even cosmetics, according to a new study published final calendar week in the periodical Environmental Science and Applied science Letters.
More half of all cosmetics tested in the study contained high levels of toxic Per- and polyfluoroalkyl substances (PFAS), reports Mathew Daly for the Associated Press. The study is the first to screen cosmetics for the total amount of PFAS present in makeup.
University of Notre Matriarch researchers tested 231 frequently-used makeup products, including liquid foundation, concealer, blush, lipsticks, and mascara, reports Tom Perkins for the Guardian. Approximately 82 percentage of waterproof mascaras, 63 percent of foundations, and 62 percent of liquid lipsticks contained at least 0.384 micrograms of fluorine per square centimeter of production spread out, reports Maria Temming for Scientific discipline News. After analyzing 29 cosmetics containing the highest amounts of PFAS, these products were found to contain four chemicals that further break down into other highly toxic PFAS, such as perfluorooctanoic acid, which can cause cancer and depression infant nativity weights, per Scientific discipline News.
"Moreover, the types of products that tested positive for high levels of fluorine—and thus probable to contain PFAS—are oftentimes used close to and effectually the eyes and lips," Whitney Bowe, a dermatologist at the Icahn School of Medicine, who was non part of the report, tells CNN'southward Sandee LaMotte.

The eyes, skin, and lips are vulnerable to absorption of the toxic chemicals. PFAS are captivated through thin mucus membranes close to the mouth and tear ducts. Lipstick is more than probable to be accidentally ingested, and wearers may consume up to several pounds of the cosmetic throughout their lives, explains written report co-author Graham Peaslee, a physicist at the University of Notre Matriarch, in a statement. Besides direct exposure through makeup, PFAS tin finish up in drinking water later on being washed off the skin, Science News reports.
PFAS are added to cosmetics to increase their long-term wearability and make peel appear shimmery and shine, CNN reports. The compounds increase durability, production consistency and h2o resistance. Considering PFAS do not breakdown in water, cosmetics designed to stay on longer or marketed as "wear-resistant," "long-lasting," and "waterproof" contained the highest levels of the chemicals, the Guardian reports. All the same, the researchers were unsure if cosmetic companies are aware that their products are infused with fluorine.
"It's not clear whether the brands are actually proverb 'Give us PFAS to use in our products or asking for a thickener, for example, or something functional without paying too much attention to what'south in it," says study co-author Tom Bruton, a chemist at the Green Science Policy Institute, to the Guardian.
In 88 percentage of all tested products, the label did not disclose PFAS to the consumer, making it almost incommunicable to avoid the toxins, reports CNN.
While half the makeup tested contained PFAS, the other half did not, which demonstrates that products can be manufactured without the chemicals, the Guardian reports.
