  • Applications

    Triethylhexyl Citrate (CAS 7147-34-4) is primarily used as a non-phthalate plasticizer for polymers such as PVC and other plastic resins, imparting flexibility and processing compatibility. It also serves as a solvent and plasticizer in coatings, inks, and adhesives within industrial formulations. In cosmetics and personal care, TEHC can function as an emollient and solvent, improving feel and formulation stability. In pharmaceutical applications, it is used as an excipient and solvent for film coatings and dosage forms, helping film integrity and controlled release. In cleaning and industrial products, TEHC is used as a solvent for fragrance oils and as an additive in resin and adhesive systems.
