Study: Half of US cosmetics contain toxic chemicals

More than half the cosmetics sold in the United States and Canada are awash with a toxic industrial compound associated with serious health conditions, including cancer and reduced birth weight, according to a new study

WASHINGTON -- More than half the cosmetics sold in the United States and Canada are awash with a toxic industrial compound associated with serious health conditions, including cancer and reduced birth weight, according to a new study. Researchers at the University of Notre Dame tested more than 230 commonly used cosmetics and found that 56% of foundations and eye products, 48% of lip products and 47% of mascaras contained fluorine — an indicator of PFAS, so-called “forever chemicals” that are used in nonstick frying pans, rugs and countless other consumer products. Some of the highest PFAS levels were found in waterproof mascara (82%) and long-lasting lipstick (62%), according to the study published Tuesday in the journal Environmental Science & Technology Letters. Twenty-nine products with higher fluorine concentrations were tested further and found to contain between four and 13 specific PFAS chemicals, the study found. Only one item listed PFAS, or perfluoroalkyl and polyfluoroalkyl substances, as an ingredient on the label. A spokeswoman for the U.S. Food and Drug Administration, which regulates cosmetics, said the agency does not comment on specific studies. The FDA said on its website that there have been few studies of the presence of the chemicals in cosmetics, and the ones that have been published generally found the concentration is at very low levels not likely to harm people, in the parts per billion level to the 100s of parts per million.
