  • Applications

    Ethyl tricosanoate (CAS number: 18281-07-7) is a long-chain fatty acid ethyl ester commonly used as an emollient in cosmetics and personal care formulations; it can function as a fragrance carrier or texture-enhancing solvent in perfumery; in polymers and plastics it serves as a plasticizer or processing aid to improve flexibility and processability; in coatings and inks it helps adjust rheology and film formation; in adhesives it acts as a plasticizer to enhance flexibility and open time; and in industrial manufacturing it can be used as a synthetic lubricant or processing aid for metalworking and plastics processing, subject to local regulations and formulation limits.
