  • Applications

    Hentriacontan-16-ol is a long-chain alcohol used as an emollient and cosmetic ingredient, providing slip and conditioning in skin care formulations. It is also evaluated as an additive in polymer and plastic systems to enhance lubricity and influence processing and material structure. In coatings and paints, it may function as a wax-like component to improve gloss and processing properties. Additionally, as an organic synthesis intermediate, it can participate in the preparation of specialty chemicals and formulations. It may also serve as a processing aid or solvent in niche industrial formulations, subject to local regulations and formulation limits.
