  • Applications

    Ditetradecyl adipate (CAS 26720-19-4) is commonly used as a plasticizer for PVC and other polymers, improving flexibility and processability. It also serves as a processing aid in coatings, inks, and adhesives. It can function as a lubricant additive in industrial manufacturing and metalworking fluids. In cosmetics and personal care formulations, it acts as an emollient and solvent/vehicle, contributing to texture and slip. It may be used as an intermediate in the synthesis of other ester-based plasticizers and related specialty chemicals.
