Propylene glycol is an important raw material for the production of unsaturated polyester, epoxy resin, polyurethane resin, plasticizer and surfactant. It has excellent bactericidal properties and wettability, and can be miscible with many substances. It is the solvent of grease, paraffin, resin, dye, etc., in advanced antifreeze, as wetting agent, dissolving agent.
 

Use
1. Carrier solvent; Wetting agent; Humectant; Anti-caking agent; Antioxidants; Tissue improver; Surfactant; Stabilizer; Thickening agent; Dough conditioner; Emulsifier; Flavoring agent; Excipient; Processing AIDS.
2. Mainly used in various spices, colors, preservatives solvent, vanilla bean, roasted coffee granules, natural flavor extraction solvent. A moisturizing and softening agent for sweets, breads, packaged meats, cheeses, etc. It can also be used as an anti-mildew aid for noodles and fillings. Adding 0.006% to soy milk can make the flavor unchanged when heated, and make white and shiny packaged tofu, which is bulked up when fried in oil.
3. Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, polyurethane resin, the amount of this aspect accounts for about 45% of the total consumption of propylene glycol, this unsaturated polyester is widely used in surface coatings and reinforced plastics. Propylene glycol is viscous and hygroscopic, and non-toxic, so it is widely used as hygroscopic agents, antifreeze agents, lubricants and solvents in the food, pharmaceutical and cosmetic industries. In the food industry, propylene glycol reacts with fatty acids to form propylene glycol fatty acid ester, which is mainly used as food emulsifier.
4. Propylene glycol is an excellent solvent for flavoring and coloring. Propylene glycol is often used in the pharmaceutical industry as a solvent, softener and excipient for the manufacture of various ointments and ointments. Because propylene glycol has good miscibility with various spices, it is also used as a solvent and softener for cosmetics. 5. Propylene glycol is also used as a tobacco humidifier, anti-mold agent, food processing equipment lubricating oil and food marking ink solvent. The aqueous solution of propylene glycol is an effective antifreeze agent.
