  • Applications

    Dioctyldodecyl Malate (CAS 63623-64-3) is an alkyl malate ester with long-chain alkyl groups used primarily as a plasticizer for polymers and coatings, helping to increase flexibility and processability in PVC, polyolefins, and other polymer systems. It is also employed as a processing aid and lubricant in plastics processing, coatings, and adhesive formulations to reduce shear and improve flow. In cosmetics and personal care, it can function as an emollient and as a solvent or carrier for active ingredients and colorants. Additionally, this long-chain malate ester may serve as a fragrance solvent or carrier in perfumery and flavor applications, and as a solvent or softening agent in cleaning products and household formulations, with usage subject to local regulations and formulation limits.
