Senate bill would ban toxic ‘forever chemicals’ in makeup, which new study found are often unlabeled

Cosmetics distributed in the United States and Canada are rife with a class of chemicals that have been associated with a number of diseases, including cancer, and frequently aren’t labeled accurately, according to a new study.

Over the last three years, researchers tested 231 cosmetics products in North America for fluorine, an indicator of per- and polyfluoroalkyl substances, or PFAS. The study found fluorine in 56 percent of foundations and eye products, 48 percent of lip products and 47 percent of mascaras.
