Application

Propylene glycol is used for similar applications as other glycols.
Propylene glycol is an important raw material for unsaturated polyester, epoxy resin, and polyurethane resin. The use amount in this area accounts for about 45% of the total consumption of propylene glycol. Such unsaturated polyester is used extensively for reinforced plastics and surface coatings. Propylene glycol is excellent in viscosity and hygroscopicity and is non-toxic, and thus is widely used as hygroscopic agent, antifreeze, lubricants and solvents in the food, pharmaceutical and cosmetic industry. In the food industry, propylene glycol reacts with fatty acid to give propylene ester of fatty acids, and is mainly used as food emulsifier; Propylene glycol is a good solvent for flavorings and pigments. Propylene glycol is commonly used as solvents, softeners and excipients, etc. in the pharmaceutical industry for the manufacture of various types of ointments and salves. Propylene glycol is also used as a solvent and a softener for cosmetic since it has good mutual solubility with various spices. Propylene glycol is also used as tobacco moisturizing agents, antifungal agents, food processing equipment lubricants and solvents for food marking ink. Aqueous solution of propylene glycol is an effective anti-freeze agent.

Storage methods

Keep away from light: propylene glycol should be stored in a dark environment to prevent its chemical reaction due to light.
Store in a ventilated and dry place: propylene glycol should be stored in a ventilated and dry place to ensure its stability.
Sealed storage: in order to prevent propylene glycol from contacting with oxygen or other impurities in the air, it should be sealed and stored.
Storage in a cool place: propylene glycol should be stored in a cool place to avoid high temperature environment to extend its service life.
Fire prevention: pay attention to fire prevention during storage to ensure the safety of the storage environment.
