  • Applications

    Oleyl caprylate (CAS 19149-86-1) is a fatty ester commonly used as an emollient and skin-conditioning ingredient in cosmetics and personal care formulations, providing slip and moisture without a greasy feel. It is also employed as a solvent or carrier for fragrance oils in perfumery, helping dissolve and distribute aroma compounds. In polymers and coatings, the ester can act as a plasticizer or processing aid, improving flexibility and flow, while in general industrial manufacturing it may serve as an intermediate or processing solvent in formulation synthesis. It is typically used in small to moderate amounts and is subject to local regulations and formulation limits.
