  • Applications

    Dipotassium lauryl sulfosuccinate (CAS 122557-66-8) is an anionic surfactant that functions as an emulsifier, wetting agent and cleansing aid in a range of industrial and consumer formulations. In cosmetics and personal care, it provides mild cleansing and foaming in shampoos, body washes and facial cleansers. In household cleaning products, it acts as a surfactant and emulsifier to improve dirt removal and formulation stability. In industrial manufacturing, it is used as a surfactant, wetting agent and dispersant in cleaners, metalworking fluids and latex or polymer processing. In coatings and inks, it serves as a pigment dispersant and flow facilitator to enhance apply-and-stop properties. In polymer and plastics processing, it can stabilize emulsions and act as a processing aid in latex or polymer formulations. In agriculture, it may be used as an adjuvant/surfactant to improve spread and uptake of agrochemical formulations. Subject to local regulations and formulation limits.
