Summary: Perfluoroalkyls are stable, synthetic chemicals. Perfluoroalkyls are unique because they repel oil, grease, and water. The two perfluoroalkyls made in the largest amounts in the U.S. are perflurooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). Perfluoroalkyls have been used in surface protection products such as carpet and clothing treatments and coating for paper and cardboard packaging. They have also been used in fire-fighting foams.

Toxicological Profile - Succinctly characterizes the toxicologic and adverse health effects information for a hazardous substance.

ToxGuidepdf icon[158 KB] - Quick reference guide providing information such as chemical and physical properties, sources of exposure, routes of exposure, minimal risk levels, children's health, and health effects for a substance.

Minimal Risk Levels (MRL) - The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure.
