  • Applications

    Heptyl stearate (CAS 24466-84-0) is a fatty ester used primarily as an emollient and a light solvent in cosmetics and personal care, providing slip and skin-conditioning properties; it also serves as a carrier or diluent for fragrance oils in perfumery, and as a processing aid and plasticizer in coatings, inks and polymer formulations; in industrial manufacturing it may function as a lubricating additive or solvent for formulation components; and it can act as an intermediate in chemical syntheses where a long-chain fatty ester is appropriate.
