Per- and polyfluoroalkyl substances (PFAS) are a group of manufactured chemicals containing ix,000 different compounds that have been around since the 1940s. PFAS practise not pause down and accrue in the surround and human body over time. The substances persist for long periods of fourth dimension, hence the nickname "forever chemicals." They are linked to severe health effects such as cancer, hormone disruptions, weakened allowed systems, and low birth weights. The toxic chemicals are establish in diverse everyday consumer products, including non-stick cookware, pizza boxes, stain repellants—and even cosmetics, according to a new study published final week in the journal Environmental Scientific discipline and Technology Letters.
More than than one-half of all cosmetics tested in the study independent high levels of toxic Per- and polyfluoroalkyl substances (PFAS), reports Mathew Daly for the Associated Press. The written report is the first to screen cosmetics for the full corporeality of PFAS nowadays in makeup.
University of Notre Dame researchers tested 231 often-used makeup products, including liquid foundation, concealer, blush, lipsticks, and mascara, reports Tom Perkins for the Guardian. Approximately 82 per centum of waterproof mascaras, 63 percentage of foundations, and 62 percent of liquid lipsticks contained at least 0.384 micrograms of fluorine per square centimeter of product spread out, reports Maria Temming for Scientific discipline News. After analyzing 29 cosmetics containing the highest amounts of PFAS, these products were establish to contain four chemicals that further break downwardly into other highly toxic PFAS, such equally perfluorooctanoic acid, which can crusade cancer and low babe birth weights, per Science News.
"Moreover, the types of products that tested positive for high levels of fluorine—and thus likely to comprise PFAS—are frequently used close to and around the eyes and lips," Whitney Bowe, a dermatologist at the Icahn School of Medicine, who was non part of the study, tells CNN's Sandee LaMotte.

The eyes, peel, and lips are vulnerable to absorption of the toxic chemicals. PFAS are absorbed through thin mucus membranes close to the mouth and tear ducts. Lipstick is more likely to exist accidentally ingested, and wearers may consume up to several pounds of the cosmetic throughout their lives, explains study co-author Graham Peaslee, a physicist at the University of Notre Dame, in a statement. Besides direct exposure through makeup, PFAS tin end upward in drinking water after being washed off the skin, Science News reports.
PFAS are added to cosmetics to increment their long-term wearability and make skin appear shimmery and smooth, CNN reports. The compounds increase durability, product consistency and h2o resistance. Because 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. Nevertheless, the researchers were unsure if cosmetic companies are enlightened that their products are infused with fluorine.
"It'southward not clear whether the brands are really saying 'Give us PFAS to apply in our products or asking for a thickener, for example, or something functional without paying likewise much attending to what'southward in information technology," says study co-author Tom Bruton, a chemist at the Greenish Scientific discipline Policy Institute, to the Guardian.
In 88 percent of all tested products, the label did not disclose PFAS to the consumer, making it almost impossible to avoid the toxins, reports CNN.
While half the makeup tested independent PFAS, the other half did not, which demonstrates that products tin be manufactured without the chemicals, the Guardian reports.
