Its consumption accounts for about 45% of the total consumption of propylene glycol. This kind of unsaturated polyester is widely used in surface coatings and reinforced plastics. 1,2-propanediol has good viscosity and hygroscopicity, and is widely used as hygroscopic agent, antifreeze, lubricant and solvent in food, medicine and cosmetics industry. In the food industry, 1,2-propanediol reacts with fatty acid to produce propylene glycol fatty acid ester, which is mainly used as food emulsifier; 1,2-propanediol is an excellent solvent for condiments and pigments. Due to its low toxicity, it is used as a solvent for spices and food pigments in the food industry. 1,2-propanediol is commonly used in the pharmaceutical industry as a solvent, softener and excipient for manufacturing various ointments and ointments, and as a solvent for blending agent, preservative, ointment, vitamin, penicillin, etc. in the pharmaceutical industry.
