Some of the highest levels were found in foundations (63%), waterproof mascara (82%) and long-lasting lipstick (62%), according to the study published Tuesday in the journal Environmental Science & Technology Letters.
In addition, the study found some 88% of the tested products failed to disclose on their labels any ingredients that would explain those chemical markers, even though that is a requirement
of the US Food and Drug Administration.
"It's a little shocking and hopefully a wake-up call for the cosmetics industry in terms of how widespread the PFAS contamination is across types of makeup products," said David Andrews, a senior scientist for the Environmental Working Group, or EWG, a consumer organization that maintains a database on personal care products which contain toxins
"The most common PFAS is polytetrafluoroethylene, the ingredient most commonly known as Teflon, or the coating on pans. But alll in all, we have identified 13 different PFAS chemicals in more than 600 products from 80 brands," said Andrews, who was not involved in the study.
