  • Applications

    15-Hentriacontanol (CAS 27759-56-4) is a high-molecular-weight fatty alcohol (C31) used in cosmetics and personal care as an emollient and thickener to improve texture and skin feel; it is also considered a fragrance ingredient and may function as a fixative in perfumery. In coatings and inks, it can act as a wax additive to improve slip, gloss, and water resistance. In polymers and plastics, it is used as a lubricant and processing aid during compound formulation. As an industrial intermediate, it serves in the synthesis of esters and other organic compounds.
