  • Applications

    Ammonium 1-lauryl sulfosuccinate is typically used as an anionic surfactant, providing wetting, emulsifying and dispersing actions in formulations. Real-world applications include household products (dishwashing liquids, all-purpose cleaners), cosmetics/personal care (shampoos, facial cleansers, cleansers), industrial manufacturing (emulsifier and stabilizer for polymer latexes and dispersant in paints and coatings), coatings and inks (improves wetting and pigment dispersion), and polymer/plastics processing (emulsification aid and compatibility additive in polymerizations and plastic formulations). Subject to local regulations and formulation limits.
