Purpose:
(1) Propylene glycol is an important raw material of unsaturated polyester, epoxy resin and polyurethane resin
This unsaturated polyester is widely used in surface coatings and reinforced plastics

(2) Propylene glycol has good viscosity and hygroscopicity, and is not toxic
Therefore, it is widely used as hygroscopic agent, antifreeze agent, lubricant and solvent in food, medicine and cosmetics industry

(3) In the food industry, propylene glycol reacts with fatty acids to form propylene glycol fatty acid esters, which are mainly used as food emulsifiers; Propylene glycol is an excellent solvent for condiments and pigments

(4) Propylene glycol is often used as solvent, softener and excipient for manufacturing various ointments and ointments in the pharmaceutical industry
Due to its good mutual solubility with various spices, propylene glycol is also used as solvent and softener for cosmetics

(5) Propylene glycol is also used as tobacco humidifier, mildew inhibitor, food processing equipment lubricant and food marking ink solvent
The aqueous solution of propylene glycol is an effective antifreeze
