  • Applications

    Decyl Isostearate is the ester of decyl alcohol and isostearic acid (CAS 97259-84-2) and is commonly used as an emollient and conditioning agent in cosmetics and personal care, providing slip, a light non-greasy feel, and easy spreadability in lotions, creams, foundations, and hair-care formulations. It also serves as a solvent or carrier for fragrance compounds and certain actives, aiding dispersion and formulation stability. In household and cleaning products, Decyl Isostearate can enhance a soft, conditioning feel on skin or surfaces and act as a moisturizing additive in detergents. Additionally, it may be considered as a processing aid or plasticizer in certain industrial polymer formulations, subject to regulatory and formulation constraints.
