Application:


● 1, 2-propylene glycol is an important raw material of unsaturated polyester, epoxy resin, polyurethane resin, plasticizer and surfactant, which accounts for about 45% of the total consumption of propylene glycol. This unsaturated polyester is widely used in surface coatings and reinforced plastics. 1, 2-propanediol has good viscosity and hygroscopicity, and is widely used as hygroscopicity, antifreeze, lubricant and solvent in food, pharmaceutical and cosmetic industries.

 

●  In the food industry, 1, 2-propylene glycol and fatty acid reaction to produce propylene glycol fatty acid ester, mainly used as food emulsifier; 1, 2-propanediol is an excellent solvent for flavoring and pigment. Because of its low toxicity, it is used as a solvent for spices and edible pigments in the food industry. 1, 2-propylene glycol in the pharmaceutical industry is often used to manufacture all kinds of ointments, ointments solvent, softener and excipient, in the pharmaceutical industry as a mixture, preservatives, ointments, vitamins, penicillin and other solvents. Because propylene glycol and all kinds of spices have good mutual solubility, so it is also used as a cosmetic solvent and softener and so on. 1, 2-propylene glycol is also used as a tobacco humidifier, mildew inhibitor, food processing equipment lubricating oil and food marking ink solvent. Aqueous solution of 1, 2-propanediol is an effective antifreeze agent. Also used as tobacco wetting agent, mildew inhibitor, fruit ripening preservative, antifreeze and heat carrier.
