Application
1. In the food industry, the reaction of propylene glycol and fatty acid to produce propylene glycol fatty acid ester is mainly used as food emulsifier
2. Propylene glycol has good viscosity and hygroscopicity, and is widely used as a hygroscopic agent, antifreeze, lubricant and solvent in food, medicine and cosmetics industries
3. Propylene glycol is also used as a solvent and softener in cosmetics because of its good compatibility with various spices
4. Propylene glycol is also used as tobacco wetting agent, anti - mildew agent, fruit ripening preservative, antifreeze and heat carrier
