Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin, accounting for about 45% of its total consumption. This type of unsaturated polyester is widely used in surface coatings and reinforced plastics. Propylene glycol has good viscosity and hygroscopicity, and is non-toxic, making it widely used as a humectant, antifreeze, lubricant, and solvent in the food, pharmaceutical, and cosmetics industries. In the food industry, propylene glycol reacts with fatty acids to form propylene glycol fatty acid esters, which are mainly used as food emulsifiers; propylene glycol is an excellent solvent for flavorings and pigments. In the pharmaceutical industry, propylene glycol is commonly used as a solvent, softener, and excipient in the production of various ointments and salves. Due to its good miscibility with various fragrances, it is also used as a solvent and softener in cosmetics. Propylene glycol is also used as a tobacco humectant,
