  • Applications

    Methyl octacosanoate (CAS 55682-92-3) is a long-chain wax ester widely used in cosmetics and personal care as an emollient and texture enhancer, and it can also function as a fragrance carrier or fixative in perfumery. In coatings and paints, it acts as a waxy additive to improve slip, gloss, and film formation; in polymers and plastics it can serve as a processing aid and lubricating component. It also appears in some household cleaning and polishing formulations as a wax-like ingredient to impart gloss and surface protection. Actual use depends on formulation needs and local regulations.
