Product application：
Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin. The usage in this aspect accounts for approximately 45% of the total consumption of propylene glycol. Unsaturated polyester is widely used in surface coatings and reinforced plastics. Propylene glycol has good viscosity and hygroscopicity, and is non-toxic. Therefore, it is widely used in the food, pharmaceutical, and cosmetic industries as a desiccant, antifreeze, lubricant, and solvent. 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 seasonings and pigments. In the pharmaceutical industry, it is commonly used as a solvent, softener, and excipient in the manufacture of various ointments and creams. Due to its good miscibility with various fragrances, it is also used as a solvent and softener in cosmetics and as a solvent for food processing equipment lubricants and food marking inks. The aqueous solution of propylene glycol is an effective antifreeze.
