  • Applications

    2-Ethylhexyl 12-(acetoxy)octadecanoate (CAS 61800-40-6) is a long-chain ester commonly used as a plasticizer and processing aid for polymers and plastics, helping to improve flexibility and processability in PVC and other resins; it can also function as an emollient/oil component in cosmetics and personal care formulations, providing lubricity and skin conditioning while remaining relatively inert. In coatings, paints, and inks, it may serve as a solvent or diluent and as a lubricating additive to adjust viscosity and film formation; in cleaning formulations it can act as a solvent or carrier to improve cleaning performance. Additionally, it is often used as an intermediate in the synthesis of other esters and specialty chemicals. Subject to local regulations and formulation limits.
