  • Applications

    (17Z)-17-Hexacosenoic acid (CAS 66274-43-9) is a long-chain monounsaturated fatty acid used as an oleochemical building block. In industry, it is commonly employed as an intermediate or feedstock for the synthesis of specialty esters, lubricants and plasticizers for polymers; as an emollient component or formulation aid in cosmetics and personal care; as a precursor to surfactants and tailored ester derivatives; and as a monomer or co-monomer in biobased polymers such as polyesters and polyurethanes, as well as in coatings or inks formulations, subject to local regulations and formulation limits.
