  • Applications

    Methyl acetyl ricinoleate (CAS 140-03-4) is an oleochemical ester derived from castor oil that is commonly used as a plasticizer and processing aid in polymers and coatings, helping improve flexibility and workability of PVC, polyesters, and related systems. It also serves as an intermediate in the synthesis of further oleochemical derivatives, enabling diversification of fatty ester products. In cosmetics and personal care, it functions as an emollient and solvent/carrier for active ingredients in ester-based formulations. In industrial manufacturing, it may act as a lubricant or slip agent and as a surfactant or formulation aid in cleaners and coatings. Its use in fragrance applications as a solvent or carrier for aroma compounds is also known, providing evaporative properties suitable for perfumed products. Use is subject to local regulations and formulation limits.
