Use of Propylene Glycol

1.Used as a raw material for resins, plasticizers, surfactants, emulsifiers and demulsifiers, as well as antifreeze and heat carriers.

2. Used as gas chromatography fixed liquid, solvent, antifreeze, plasticizer and dehydrating agent.

3. Carrier solvents; humectants; humectants; anti-caking agents; antioxidants; texture modifiers; surfactants; stabilizers; thickeners; dough conditioners; emulsifiers; flavoring agents; excipients; processing aids. GB2760 ~ 96 as food processing aids. Mainly used for various spices, pigments, preservatives, solvents, vanilla beans, roasted coffee, natural flavors and other extraction solvents. Moisturizing and softening agent for candy, bread, packaged meat, cheese, etc. Can also be used as noodles, stuffing core class mildew additives. Adding 0.006% to soybean milk can make the flavor unchanged when heated to make white and shiny packaged tofu, which is fried in oil and expanded in volume.

4. Propylene glycol is an intermediate of the fungicide difenoconazole.

5. As a solvent, preservatives, pigments, antioxidants and other food additives that are difficult to dissolve in water can be dissolved in them, and then added to food; it has strong hygroscopicity and has moisturizing and antifreeze effects on food.6. Propylene glycol is an important raw material for unsaturated polyester, epoxy resin and polyurethane resin, which 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 has good viscosity and hygroscopicity, and is non-toxic, so it is widely used as a hygroscopic agent, antifreeze, lubricant and solvent in the food, pharmaceutical and cosmetic industries. In the food industry, propylene glycol and fatty acids react to produce propylene glycol fatty acid esters, which are mainly used as food emulsifiers; propylene glycol is an excellent solvent for spices and pigments. Propylene glycol in the pharmaceutical industry is often used to manufacture all kinds of ointment, ointment solvent, softener and excipient, due to propylene glycol and all kinds of spices have good mutual solubility, and thus also used as a cosmetic solvent and softener and so on. Propylene glycol is also used as a tobacco moisturizer, fungicide, food processing equipment lubricants and food marking ink solvent. Aqueous solutions of propylene glycol are effective antifreeze agents.

 7. As a drug carrier, particle drug agent. It can be used as moisturizer, softener, solvent and so on in cosmetics. In the tobacco industry, it can be used as tobacco flavor, tobacco moisturizer, preservative, etc. In the food industry, it is used as a solvent for flavors, food pigments, food packaging softeners, food anti-sticking agents, etc. Can also be used in the production of unsaturated polyester resin, plastic plasticizer, dehydrating agent, surfactant, curing agent, binder raw materials. Can also be used in paint, pesticides, coatings and other industries.
