  • Applications

    8,11,14-Eicosatrienoic Acid (CAS 7324-41-6) is a long-chain polyunsaturated fatty acid used as a chemical intermediate and feedstock across several sectors. In cosmetics and personal care, it can be converted to emollient esters and conditioning ingredients. In industrial manufacturing, it serves as a raw material for specialty lubricants and plasticizers. It can also be converted into fatty acid esters that act as surfactants and emulsifiers. In coatings and inks, it can be derived into precursors for alkyd or polyurethane resins. In polymer chemistry, it provides a functionalized fatty acid backbone for various polymer applications; usage depends on formulation needs and local regulations.
