  • Applications

    Steardimonium ethyl stearyl phosphate, CAS 250588-57-9, is a cationic surfactant and phosphate ester with hydrophobic stearyl and ethyl stearyl segments. In industrial practice, it is used as a conditioning agent and surfactant in cosmetics and personal care formulations (shampoos, conditioners, body washes) to improve conditioning feel and emulsion stability. It can also be used in household cleaners and laundry products to enhance emulsification and formulation stability. Additionally, it plays a role as a surfactant and additive in polymer processing and textile finishing (emulsification, wetting and antistatic properties during processing), and is used in coatings, inks and adhesives to improve wetting and surface distribution. Use depends on local regulations and formulation limits.
