  • Applications

    Disodium lauryl sulfosuccinate (CAS 19040-44-9) is an anionic surfactant widely used as a surface-active agent, emulsifier, and wetting agent in household detergents and related cleaners. In cosmetics and personal care, it commonly serves as a foaming cleanser and as an emulsifier/stabilizer for oil-in-water formulations. In industrial formulations, it acts as a wetting and dispersing agent in coatings, paints, and inks to improve surface wetting and pigment dispersion. It is also used as an emulsification or dispersion aid in polymer processing and latex formulations. Additionally, as a surfactant, it may be evaluated for use in agricultural formulations as an adjuvant to improve wetting and spread. Use is subject to local regulations and formulation limits.
