Product Features
  • Dipropylene Glycol (DPG) is a co- product from the manufacture of monopropylene glycol. It is colorless, practically odorless, water soluble, medium viscosity hygroscopic liquid with low vapor pressure and low toxicity. DPG is utilized as a solvent, coupling agent and chemical intermediate in numerous industries, having a wide range of practical applications.
  • DPG’s excellent solvency for certain oils, low evaporation rate and low toxicity lend its use in brake fluid formulations, cuttings oils, textile lubricants, printing inks, coatings, industrial soaps and as a solvent for agricultural and insecticidal formulations.

Storage Information

DPG is stable for at least one year when stored at ambient temperatures in closed containers and away from sunlight and other sources of UV light. Where product heating is utilized (bulk storage and/or transport containers) the product temperature should be controlled to prevent unintentional overheating over extended periods as this may potentially lead to accelerated oxidative degradation of the product. As a general guide do not heating above 40°C.
