  • Applications

    (11Z)-icos-11-en-1-ol (CAS 62442-62-0) is a long-chain unsaturated fatty alcohol that finds primary use as a fragrance ingredient and fixative in perfumery, helping to provide lasting aroma notes in cosmetic and personal-care formulations. It can also act as an emollient and texture enhancer in skincare products. In industrial manufacturing it serves as an intermediate for the synthesis of esters, including fragrance esters and specialty lubricants, and can be a feedstock for waxes and other specialty chemicals. Additionally, when functionalized it can be a precursor for nonionic surfactants or coating additives, contributing to slip, gloss, and compatibility in coatings and inks. Its use is subject to local regulations and formulation limits.
