Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin, accounting for approximately 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 hygroscopic properties and is non-toxic, making it widely used in the food, pharmaceutical, and cosmetics industries as a humectant, antifreeze, lubricant, and solvent. In the food industry, propylene glycol reacts with fatty acids to form propylene glycol fatty acid esters, which are primarily 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,
