  • Applications

    Trihexyl acetyl citrate, CAS 24817-92-3, is primarily used as a non-phthalate plasticizer for polymers, notably PVC and resin systems based on cellulose and polyester, improving flexibility and processability. It also serves as a processing aid in coatings, inks, and adhesives, aiding film formation and viscosity control. In cosmetics and personal care, it can function as a solvent or plasticizer in formulations. It is studied as a compatible plasticizer for biopolymers and sustainable polymer systems, and may be employed as a solvent or additive in cleaning products under applicable regulatory limits.
