1,Basic introduction
1,2-propylene glycol is an organic compound with the chemical formula C3H8O2, which is miscible with water, ethanol and various organic solvents.Under normal circumstances, it is a colorless viscous liquid, almost odorless, and slightly sweet in smell.Propylene glycol can be used as a raw material for unsaturated polyester resins, and can be used as a wetting agent in combination with glycerin or sorbitol in cosmetics, toothpaste and soap.It is used as a humidifier and hair leveling agent in hair dyes, as well as an antifreeze agent, and is also used in cellophane, plasticizers.
 
2,The main role
1,2-propylene glycol is an important raw material for 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 unsaturated polyester is widely used in surface coatings and reinforced plastics.1,2-propylene glycol has good viscosity and hygroscopicity, and is widely used as a hygroscopic agent, antifreeze agent, lubricant and solvent in the food, and cosmetic industries.In the food industry, 1,2-propylene glycol reacts with fatty acids to form propylene glycol fatty acid esters, which are mainly used as food emulsifiers; 1,2-propylene glycol is an excellent solvent for condiments and pigments.Due to its low toxicity, it is used as a solvent for spices and food coloring in the food industry.1,,2-propylene glycol is often used in the pharmaceutical industry as a solvent, softener and excipient for the manufacture of various ointments and ointments, etc.
Because propylene glycol has good miscibility with various fragrances, it is also used as a solvent and softener for cosmetics and so on.1,2-propylene glycol is also used as a humidifier for tobacco, an antifungal agent, a lubricant for food processing equipment, and a solvent for food marking inks.An aqueous solution of 1,2-propylene glycol is an effective antifreeze agent.It is also used as a wetting agent for tobacco, an antifungal agent, a fruit ripening preservative, an antifreeze, and a heat carrier.
 
3,The main purpose
It is an important raw material for unsaturated polyester, epoxy resin, polyurethane resin, plasticizer, and surfactant.This unsaturated polyester is widely used in surface coatings and reinforced plastics.Widely used as hygroscopic agent, antifreeze agent, lubricant and solvent
