Per- and polyfluoroalkyl substances, PFAS, are synthetic, man-made chemicals found in many products meant for daily use. Studies have shown that exposure to PFAS leads to adverse health effects on the environment and humans. This is, in part, due to the fact that PFAS do not readily break down and bioaccumulate over time. Thus, work centered on identifying both expected and unexpected exposure routes is critical. Researchers have also found PFAS in cosmetic products. This, combined with the fact that studies have shown that PFAS exposure through the skin can be just as harmful as ingestion, suggests a more comprehensive look at the presence of PFAS in various types of cosmetics. In this study, 40 different cosmetics were chosen based on whether or not they claim to be synthetic free and where they were manufactured. Liquid chromatography-tandem mass spectrometry (LC-MS) was used to identify PFAS compounds and determine which cosmetic products had the most PFAS. The hypothesis is that synthetic-free cosmetics should have fewer to no PFAS levels compared to their synthetic counterparts. The second hypothesis is that products made in the People’s Republic of China will have higher concentrations of PFAS, when compared to products made in the US.
