  • Applications

    Cetearyl Stearate (CAS 93820-97-4) is widely used in cosmetics and personal care as an emollient, texture enhancer, and stabilizing wax-like ingredient in creams, lotions, and hair-care formulations; it also serves as a fragrance carrier in perfumery formulations, helping to solubilize and deliver fragrance components. In addition, it is employed as a processing aid and slip agent in polymer and plastics processing to improve lubrication and handling, and can function as a waxy additive in coatings and household products to impart gloss and a smooth feel. These roles are common across formulation contexts and are subject to local regulations and formulation limits.
