Perfluorooctanoic acid (PFOA), also known as C8 and perfluorooctanoate, is a synthetic perfluorinated carboxylic acid and fluorosurfactant.FOA has widespread applications. In 1976, PFOA was reported as a water and oil repellent in fabrics and leather and in the production of floor waxes and waxed papers ; however, it is believed that paper is no longer treated with perfluorinated compounds, but with fluorotelomers with less than 0.1% PFOA.
