  • Applications

    Hydroxystearyl cetyl ether (CAS 78509-74-7) is commonly evaluated as a nonionic surfactant/emulsifier in cosmetics and personal care formulations, providing conditioning and emulsion stability for oils and water in lotions, creams, and hair care systems. It may serve as a slip or texture‑enhancing agent in coatings and inks, aiding film formation and component compatibility. In household cleaners and related formulations, it can act as an emulsifier/solubilizer for oils and soils. In polymer and plastics processing, it may function as a processing aid, lubricity additive, or compatibility agent in blends. It is sometimes encountered as an intermediate in surfactant synthesis and other industrial formulations. Use is subject to local regulations and formulation limits.
