  • Applications

    Methyl trans-6-Octadecenoate (CAS 14620-36-1) is the methyl ester of trans-6-octadecenoic acid, a long-chain fatty acid methyl ester used across several industrial applications. In energy and chemical processing, it may serve as a fatty ester feedstock for biodiesel production. In polymers and coatings, it is commonly used as a plasticizer and processing aid for PVC, coatings, and adhesives to improve flexibility and handling. In cosmetics and personal care, it functions as a solvent and an emollient ingredient in formulations. In cleaning and household formulations, it may act as a solvent or carrier for active ingredients. These applications are subject to local regulations and formulation limits.
