  • Applications

    Tristearyl Citrate (CAS 7775-50-0) is the triester of citric acid with three stearyl groups; it is commonly used as a non-phthalate plasticizer for plastics and coatings (notably PVC and related polymers) to improve flexibility and processability; it also serves as an emollient and conditioning agent in cosmetics and personal care products; in industrial manufacturing it functions as a processing aid and lubricant to support molding, extrusion, and coating applications; it can be employed as an intermediate in the synthesis of other citrate esters; and it may act as a carrier or solvent in specialized formulation systems, subject to local regulations and formulation limits.
