Summary: Perfluorooctanoic acid (PFOA, also known as C8) is a member of the perfluoroarlkyl and polyfluoroalkyl substances (PFAS). It is widely used in adhesives, cosmetics, paints, and greases. It may be used as a surfactant and an intermediate in chemical synthesis. It is also used for its water and grease repelling properties. It is used in the production of Teflon. It has been phased out of use since 2002. It is very persistent in the environment and may travel long distances if used as an aerosol. It is soluble in water up to 2,290 mg/L at 24 C and has a density of 1.792 g/mL at 20 C. It has a biological half-life in humans of 2.4 years. As a vapor in the atmosphere it will degrade with a half-life of 31 days. Moderate mobility is expected within soil.
