Perfluorooctanoic acid: History, Applications & Products

Perfluorooctanoic acid (PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, from its chemical formula C8HF15O2) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a chemical precursor. PFOA is considered a surfactant, or fluorosurfactant, due to its chemical…
