PFOS-related substances (perfluorooctylsulfonyl compounds, degrades to PFOS) are used in: textile, carpet and leather protection (dirt repellents); photographic films, papers (surfactants; electrostatic charge, friction control agents; dirt repellents, adhesion control agents, anti-static); in flame retardants; paper and packaging (dirt repellents); fire fighting foams (surfactants) (It is suggested that PFOS is no longer used in these foams, but may be maintained and emergency used as fire fighting stock); in industrial and household cleaning products (wetting improvers); coatings: in the paint, floor waxes, pigment and finishing industries (emulsifier, levelling, gloss and anti-static improvers; pigment grinding agents, foam generator); as surfactant for etching acids for circuit boards /K, Li, DEA, NH4 Salts/
