  • Applications

    Disodium 1-octadecyl 2-sulphonatosuccinate (CAS 65277-59-0) is an anionic surfactant featuring a long C18 hydrophobic tail and a sulfonate head, typically used as a wetting, emulsifying and dispersing agent. In industry, it serves as a surfactant to improve formulation stability, reduce surface tension, and aid pigment and particle dispersion in coatings and inks. In cosmetics and personal care, it functions as a cleansing surfactant and emulsifier in cleansers, shampoos and creams. In household cleaning products, it acts as a detergent additive to enhance cleaning performance and oily soil emulsification. In polymer processing and plastics, it can be used as a stabilizing or dispersing agent for latexes and polymer emulsions. It may also be evaluated as an adjuvant surfactant in agricultural formulations to improve wetting and spray deposition. It can be used as an intermediate in the synthesis of more complex surfactants. Formulation use is subject to local regulations and limits.
