  • Applications

    Hexyldecyl Stearate (CAS 17618-45-0) is a long-chain fatty ester derived from stearic acid and hexyldecyl alcohol, used primarily as an emollient and slip agent in cosmetics and personal care, providing a smooth, silky feel in creams, lotions, and makeup bases; it also serves as a carrier for fragrance oils in perfumery formulations, aiding distribution and scent stability. In household products, it is used as a conditioning/oiling component in cleaners and fabric care products. In industrial manufacturing, it can act as a processing aid and plasticizer in polymer and plastics formulations to impart flexibility and slip. In coatings and inks, it may serve as a flow modifier and lubricating additive to improve application and film formation. It can also serve as a processing aid in adhesives. Use is subject to local regulations and formulation limits.
