  • Applications

    Trilinoleic acid (CAS 7049-66-3) is a triglyceride composed of three linoleic acid units bound to glycerol. In industry, it serves as an oleochemical feedstock and lipid component for structured lipids; commonly used in cosmetics and personal care as an emollient and carrier oil; used as a fat/oil ingredient in food processing to supply polyunsaturated fatty acids; a raw material for the synthesis of esters, lubricants, and plasticizers via transesterification; can be hydrolyzed to recover linoleic acid and glycerol for downstream derivatives such as surfactants or fatty acids; subject to local regulations and formulation limits.
