  • Applications

    Cetyl octanoate (CAS 29710-31-4) is primarily used as an emollient and conditioning agent in cosmetics and personal care, providing slip, improving spreadability, and contributing to the texture of creams, lotions, and related products. It also serves as a solvent or carrier for fragrance oils and certain actives in perfumery and cosmetic formulations. As a wax ester, it can act as a texture enhancer and help form stable emulsions. In hair care, it functions as a conditioning oil that softens and detangles. It may also function as a processing aid such as a lubricant or plasticizer in polymer formulations and coatings, depending on the formulation and regulatory constraints.
