  • Applications

    Octadec-9-enyl icosanoate (CAS 156952-79-3) is a long-chain wax ester derived from oleyl alcohol and arachidic acid. In cosmetics and personal care, it is commonly used as an emollient and conditioning agent, providing lubrication, slip, and a smooth skin feel. In polymer and plastics formulations, it can act as a plasticizer and processing aid for certain wax blends and thermoplastics, improving flexibility and handling. In coatings and inks, it serves as a wax-like additive to enhance gloss, slip, and surface feel. It can also function as a specialty lubricant component in industrial oils and lubricants. Its use is subject to local regulations and formulation limits.
