Propylene glycol serves a similar range of applications as its glycol counterparts, offering versatility and efficacy across various industries.
Propylene glycol is an indispensable raw material, particularly for unsaturated polyester, epoxy resin, and polyurethane resin production. This application alone represents approximately 45% of the total propylene glycol consumption, underlining its significance. Unsaturated polyester is extensively utilized in reinforced plastics and surface coatings, providing exceptional viscosity and hygroscopic properties while being non-toxic. This makes propylene glycol a favored choice in the food, pharmaceutical, and cosmetic industries as a hygroscopic agent, antifreeze, lubricant, and solvent. In the food sector, it interacts with fatty acids to form propylene esters, primarily employed as food emulsifiers. Additionally, propylene glycol is a superb solvent for flavorings and pigments. In pharmaceuticals, it acts as a solvent, softener, and excipient in various ointments and salves. Cosmetic applications benefit from its excellent solubility with spices, serving as a solvent and softener. Moreover, it finds roles as a *** moisturizing agent, antifungal agent, lubricant for food processing equipment, and solvent for food marking ink. Propylene glycol's aqueous solution is a superior antifreeze agent, showcasing its multifaceted usage and contribution to modern industry.
