Propylene glycol serves a similar range of applications as its glycol counterparts, offering versatility and efficacy across various industries.
Propylene glycol is an essential powerhouse of a raw material, vital for the manufacture of unsaturated polyester, epoxy resin, and polyurethane resin. This crucial application accounts for about 45% of global propylene glycol usage, underscoring its pivotal role. Unsaturated polyester, renowned for its extensive use in reinforced plastics and surface coatings, boasts remarkable viscosity and impressive hygroscopic properties, all while maintaining a non-toxic profile. This renders propylene glycol the ideal choice in the food, pharmaceutical, and cosmetic industries, where it shines as a hygroscopic agent, antifreeze, lubricant, and solvent. In the culinary world, propylene glycol transforms fatty acids into propylene esters, predominantly used as food emulsifiers. It also excels as a solvent for flavors and pigments. Within pharmaceuticals, it serves as a solvent, softener, and excipient in numerous ointments and salves. The cosmetic industry praises its excellent compatibility with spices, using it as a solvent and softener. Furthermore, it acts as an exceptional moisturizing agent, antifungal, and lubricant for food processing equipment, as well as a solvent for food marking ink. Propylene glycol's aqueous solutions stand out as superior antifreeze agents, highlighting its diverse and indispensable applications in contemporary industry.
