  • Applications

    11-Docosenoic acid (CAS 506-36-5) is a long-chain monounsaturated fatty acid used primarily as an oleochemical feedstock. It serves as a building block for ester and surfactant synthesis and as a source of lubricants and plasticizers for polymer formulations. In cosmetics and personal care it functions as an emollient and conditioning agent, improving texture and skin feel. In coatings and inks it can act as a fatty-acid modifier and surface-active additive, and it may also be employed in fragrance chemistry as a precursor for fragrance esters. Use is typically as an intermediate or oleochemical-derived additive, subject to local regulations and formulation limits.
