| Propylen glycol is used for similar applications as other glycols. Propylen glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin. The use amount in this area accounts for about 45% of the total consumption of propylen glycol. Such unsaturated polyester is used extensively for reinforced plastics and surface coatings. Propylen glycol is excellent in viscosity and hygroscopicity and is non-toxic, and thus is widely used as hygroscopic agent, antifreeze, lubricants and solvents in the food, pharmaceutical and cosmetic industry. In the food industry, propylen glycol reacts with fatty acid to give propylen ester of fatty acids, and is mainly used as food emulsifier; Propylen glycol is a good solvent for flavorings and pigments. Propylen glycol is commonly used as solvents, softeners and excipients, etc. in the pharmaceutical industry for the manufacture of various types of ointments and salves. Propylen glycol is also used as a solvent and a softener for cosmetic since it has good mutual solubility with various spices. Propylen glycol is also used as tobacco moisturizing agents, antifungal agents, food processing equipment lubricants and solvents for food marking ink. Aqueous solution of propylen glycol is an effective anti-freeze agent. |
