Propylene Glycol is colorless and transparent liquid. The melting Point is 60℃. Boiling Point is195.1°C at 760mmHg. Flash Point is 85.7°C. Water Solubility is miscible.
PG is the main raw material of unsaturated polyester, epoxy resin, polyurethane resin. In food, medicine and cosmetics industry is widely used as a hygroscopic agent ,antifreeze, lubricants and solvents. In the food industry it is a good solvent, spices and pigments. In medicine it is in the production of various types of ointment, gel solvent, softener and excipients, etc. Propylene glycol and various spices has good solubility which is also used as a solvent and cosmetics, etc. softener can also be used as a tobacco humidification agent and moisturizing agent, fungicide, food processing equipment, lubricating oil and food labeling ink solvent. Propylene glycol aqueous solution is effective antifreeze agent, it is also a kind of plasticizer, surface active agent, food emulsifying agent and demulsifier, fruit ripening agent, preservative, hygroscopic agent, lubricant, antifreeze raw materials.
