Uses of Propylene Glycol:
1.Propylene Glycol is an important raw material in unsaturated polyester, epoxy resins, polyurethane resins, plasticizers and surfactants. The amount occupies about 45% of total consumption. This unsaturated polyester is largely used for surface coatings and reinforced plastics.
2.Because of good viscosity and moisture absorption, and non-toxic, Propylene Glycol is widely used as a hygroscopic agent, antifreeze, lubricants and solvents in the food, pharmaceutical and cosmetics industries.
3.In the food industry, Propylene Glycol and fatty acid reacts to produce propylene glycol ester of fatty acid, which is mainly used as food emulsifier. It is also used as solvent for spices, seasonings and food coloring.
4.What's more, 1,2-propanediol is used as a humidifying agent of tobacco, mildew preventive, fruit ripening preservatives, film-forming coatings additives, antifreeze and heat transfer media, etc.
5.It is often used as a substitute for ethanol and glycerol. In pharmaceutical industry, Propylene Glycol is commonly used as solvent in the manufacture of various types of ointment, softener, excipients, preservatives, vitamins, penicillin, etc. As Propylene Glycol has good solubility with various spices, it is also used as solvent of cosmetic and softeners, etc.
