Propylene glycol dibenzoate

Propylene glycol dibenzoate (CAS 19224-26-1), also recognized by its FEMA 3419 designation, is a benzoate ester plasticizer and solvent used across polymer and coating systems. It functions as a low-volatility plasticizer and coalescent, improving flexibility and film formation in a range of industrial formulations. In PVC and vinyl compounding, it delivers efficient plasticization.

The material offers good compatibility, providing a phthalate-free alternative for flexible film, flooring, and profile applications. Coating formulators use it as a coalescent agent in waterborne systems. It aids film formation without the high VOC burden of conventional solvents. In adhesives and sealants, it improves tack, flexibility, and substrate wetting across both solvent-borne and emulsion-based systems.

Printing ink manufacturers incorporate it as a solvent-carrier to control viscosity and resin compatibility in packaging ink formulations. This versatility makes it a staple in modern chemical manufacturing. Propylene glycol dibenzoate is supplied as a clear, low-viscosity liquid. It is available in technical grade, with supply typically in drums and IBC totes for industrial volumes.

Buyers should confirm purity specifications and lot documentation directly with the supplier, as grade designations vary by manufacturer. Proper storage ensures the stability of the chemical properties over time.
