Propylene glycol (PG) is mainly used to produce unsaturated polyester resin (UPR) for surface coatings and glass fiber reinforcement. Its second major consumer use is as an antifreeze, replacing ethylene glycol in antifreeze aircraft and as a coolant in food. In addition, a large amount of propylene glycol is used to produce plasticizers and hydraulic brake fluids. It can also be used in non-ionic detergents and as a humectant in the pharmaceutical, cosmetic, animal food, and tobacco industries. In addition, propylene glycol is a solvent with good performance and can be used in printing inks and epoxy resins.
