Application
Propylene glycol function
Propylene glycol is also used as solvent and softener of cosmetics because of its good mutual solubility with various spices. 1,2-propanediol is also used as tobacco humidifier, mildew inhibitor, lubricant for food processing equipment and solvent for food marking ink. The aqueous solution of 1,2-propanediol is an effective antifreeze. It is also used as tobacco wetting agent, mildew inhibitor, fruit ripening preservative, antifreeze and heat carrier.
-
1,2-propanediol is an important raw material of unsaturated polyester, epoxy resin, polyurethane resin, plasticizer and
surfactant. The amount in this regard accounts for about 45% of the total consumption of propylene glycol. This unsaturatedpolyester is widely used in surface coatings and reinforced plastics.
