  • Applications

    Cetearyl alcohol (CAS 8005-44-5) is a fatty alcohol mixture used primarily as an emollient, thickener, and stabilizer for emulsions in cosmetics and personal care, such as creams, lotions, and hair care products, while also serving as a conditioning agent and surface lubricant to improve slip and texture. In pharmaceutical topical formulations, it may function as an inactive excipient and a viscosity modifier to enhance feel and spread. In household cleaning products, it can act as a thickener and emollient contributor to formulation stability. In polymer and plastics processing, it is used as a wax-like additive or processing aid to improve processing behavior, slip, and influence the crystalline structure of the polymer blend.
