1,2-Propylene glycol is an important raw material for unsaturated polyesters, epoxy resins, polyurethane resins, plasticizers, and surfactants. The amount in this area accounts for about 45% of the total consumption of propylene glycol. This unsaturated polyester It is widely used in surface coatings and reinforced plastics.
1,2-Propanediol has good viscosity and hygroscopicity, and is widely used as a moisture absorbent, antifreeze, lubricant and solvent in the food, medicine and cosmetic industries. In the food industry
1,2-propylene glycol and fatty acids react to produce propylene glycol fatty acid esters, which are mainly used as food emulsifiers; 1,2-propylene glycol is an excellent solvent for seasonings and pigments. Because of its low toxicity, it is used as a solvent for spices and food coloring 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, penicillins, etc. in the pharmaceutical industry . Because propylene glycol has good miscibility with various fragrances, it is also used as a solvent and softener for cosmetics.
1,2-Propanediol is also used as a tobacco moisturizer, antifungal agent, food processing equipment lubricating oil and food marking ink solvent. An aqueous solution of 1,2-propanediol is an effective antifreeze. It is also used as a tobacco wetting agent, antifungal agent, fruit ripening preservative, antifreeze and heat carrier.
