  • Applications

    Sodium stearoamphoacetate (CAS number: 68298-17-9) is used as a mild amphoteric surfactant and emulsifier in cosmetics and personal care, such as shampoos and cleansers, enabling gentle foaming and conditioning; it also serves as a surfactant and emulsifier in household cleaning formulations; it acts as a stabilizer/dispersant in polymer emulsions and industrial latex systems; and it functions as a wetting agent and surfactant in coatings and inks to improve surface wetting and component compatibility.
