  • Applications

    Oleamidopropyl Hydroxysultaine (CAS 93941-94-7) is a mild zwitterionic surfactant widely used in cosmetics and personal care for cleansing, foam performance, and conditioning benefits on hair and skin; it also finds application in household cleaning products as a gentle detergent and emulsifier. In industrial manufacturing, it acts as a surfactant and emulsifier to stabilize formulations, aid pigment and polymer dispersion, and improve cleaning efficiency in metal and equipment cleaners. In coatings and inks, it serves as a dispersant and wetting agent to enhance pigment dispersion and film formation. In polymers and plastics processing, it can function as a processing aid or emulsifier to support emulsion polymerization and blend compatibility. Additionally, it may be used as a surfactant or dispersing agent in adhesives to improve wetting and adhesion.
