Documented Uses

• Protective coatings for fabrics and carpet, paper coatings, insecticide formulations, surfactants /Perfluorchemicals/
• Long-chain perfluoroalkanecarboxylic acids and their salts are surface-active chemicals (surfactants), which greatly reduce the surface tension (surface energy) of water, aqueous solutions, and organic liquids even at low concentrations. These acids (C6-C12) and derivatives are used as wetting, dispersing, emulsifying, and foaming agents. /Long-chain perfluoroalkanecarboxylic acids/
• non-polymer PFAS -> Laboratory Supplies -> Impregnation of genuine leather
• non-polymer PFAS -> Personal Care products and cosmetics -> BB/CC cream, foundation
• non-polymer PFAS -> Building and Construction -> Greenhouse
• non-polymer PFAS -> Personal Care products and cosmetics -> Concealer/corrector
