  • Applications

    Butyl glycolyl butyl phthalate (CAS number: 85-70-1) is a phthalate ester commonly used as a plasticizer for PVC and other polymers to improve flexibility and processability. It also serves as a processing aid and solvent in coatings, paints, and inks, providing formulation-friendly viscosity control and compatibility with resin systems. In adhesives, it acts as a plasticizer and formulation aid to enhance adhesion and flexibility of bonded assemblies. In perfumery, it may be used as a fixative to modulate fragrance release. In cosmetics and personal care, it can function as a solvent and plasticizer within regulatory limits.
