Propylene glycol mirrors the adaptability and efficiency of its glycol family, making it an essential component across a multitude of industries.
Propylene glycol is a vital raw material, especially in the production of unsaturated polyester, epoxy resin, and polyurethane resin. This specific application accounts for about 45% of the total usage of propylene glycol, highlighting its critical importance. Unsaturated polyester is widely used in reinforced plastics and surface coatings, thanks to its remarkable viscosity and hygroscopic nature, while also being non-toxic. Such properties make propylene glycol a preferred ingredient in the food, pharmaceutical, and cosmetic industries, serving as a hygroscopic agent, antifreeze, lubricant, and solvent. In the food industry, it combines with fatty acids to create propylene esters, predominantly utilized as food emulsifiers. Furthermore, propylene glycol excels as a solvent for flavorings and pigments. In the pharmaceutical industry, it functions as a solvent, softener, and excipient in various ointments and salves. Cosmetic applications take advantage of its excellent solubility with spices, using it as a solvent and softener. Additionally, it acts as a moisturizing agent, antifungal agent, lubricant for food processing equipment, and as a solvent for food marking ink. Its aqueous solution serves as an outstanding antifreeze agent, demonstrating its diverse and essential contributions to modern industry.
