  • Applications

    Octadecyl butyrate (CAS 13373-83-6) is a long-chain aliphatic ester typically used as an emollient and skin-conditioning ingredient in cosmetics and personal care products, providing slip and moisturization in moisturizers, creams, and related formulations. It may function as a non-volatile carrier or solvent in fragrance compositions and cosmetic bases, aiding the dispersion of fragrance components. In industrial manufacturing, it can act as a plasticizer and processing aid for polymers and coatings, improving flexibility and handling of waxy systems. It can also serve as a waxy additive to enhance texture, gloss, and slip in coatings and inks. In perfumery, it may be used as a fragrance ingredient or fixative to help stabilize scent profiles, with use subject to formulation limits and regulatory controls.
