  • Applications

    9-Hexadecen-1-ol (CAS 64437-47-4) is a long-chain alkenyl alcohol used primarily as a fragrance ingredient and as a chemical intermediate. In perfumery, it serves as an odorant and can act as a fixative. In cosmetics and personal care, it may function as an emollient and as a building block for ester derivatives used in formulations. In household products, it can appear as a fragrance component or solvent modifier. In industrial manufacturing, it is employed as an intermediate for the synthesis of esters, surfactants, and specialty lubricants. In the polymers and coatings/inks sectors, it can serve as a precursor for specialty esters or be used to adjust processing properties while contributing fragrance.
