Use: propylene glycol unsaturated polyester, epoxy resin, polyurethane resin material, the amount accounted for about 45% of the total consumption of propylene glycol, such a large number of unsaturated polyester used in surface coatings and reinforced plastics. Propanediol viscous and hygroscopicity good, and non-toxic, and thus in the food, pharmaceutical and cosmetic industry is widely used as an absorbent, antifreeze, lubricants and solvents. In the food industry, propylene glycol and fatty acid reaction of propylene glycol fatty acid esters, mainly used as a food emulsifier; propanediol condiments and pigment is an excellent solvent. Propylene glycol is commonly used in the pharmaceutical industry for the manufacture of various types of ointment, cream solvent, softener and excipients, the propylene glycol and of all kinds of spices has good mutual solubility, therefore is also used in cosmetics solvent and softener and so on. Propylene glycol is also used for tobacco humidification agent, anti-mildew agent, lubricating oil and food processing equipment and food marking ink solvent. Propylene glycol aqueous solution is effective antifreeze agent.
