1,2-Propanediol is an important raw material for unsaturated polyesters, epoxy resins, polyurethane resins, plasticizers, and surfactants. The amount used in this regard accounts for about 45% of the total consumption of propylen glycol. This unsaturated polyester Used extensively in surface coatings and reinforced plastics. 1,2-Propanediol has good viscosity and hygroscopicity, and is widely used as hygroscopic agent, antifreeze agent, lubricant and solvent in the food, pharmaceutical and cosmetic industries. In the food industry, 1,2-propanediol reacts with fatty acids to form propylen glycol fatty acid esters, which are mainly used as food emulsifiers; 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 colorings in the food industry. 1,,2-Propanediol is commonly used in the pharmaceutical industry as a solvent, softener and excipient for the manufacture of various ointments and ointments, and as a solvent for blending agents, preservatives, ointments, vitamins, penicillin, etc. in the pharmaceutical industry .
