  • Applications

    Triisopropyl citrate is primarily used as a citrate-based plasticizer and processing aid for polymers and resins, notably PVC and cellulose esters, to improve flexibility and processability. It also functions as a solvent and carrier in fragrance and cosmetic formulations, helping active ingredients dissolve and blend. In coatings, inks, and adhesives, it acts as a plasticizer and processing aid to support film formation and adhesion. In household and personal care products it may serve as a mild solvent and formulation component, subject to local regulations and formulation limits.
