Ammonium salts are ionic compounds with the formula (R)4N + A - , where R is hydrogen, alkyl or aryl groups and A is an anion. When R is alkyl or aryl then they are referred to as quaternary ammonium salts. The quaternary ammonium cations are permanently charged, independent of the pH of their solution. Most of the ammonium salts are soluble in water and strongly dissociated.

For PFOA, the majority of the aquatic ecotoxicity studies have been conducted with the ammonium salt (APFO) of the prefluorooctanoic acid. Under environmentally relevant conditions in aqueous environmental compartments, PFOA will exist as the fully ionized component (COO −). The surface active properties of the potassium salt of PFOS make a direct determination of the octanol-water partition coefficient impossible. In a preliminary study reported by 3M an inseparable emulsion was formed.
