PROPYLENE GLYCOL Tech grade CAS#57-55-6

详情

propylene glycol is an important raw material of unsaturated polyester, epoxy resin, polyurethane resin, plasticizer, surfactant, the amount of this aspect accounts for about *5% of the total consumption of propylene glycol, this unsaturated polyester is widely used in surface coatings and reinforcement plastics. propylene glycol has good viscosity and hygroscopic properties, and is widely used as hygroscopic agents, antifreeze agents, lubricants and solvents in the food, pharmaceutical and cosmetic industries. In the food industry, propylene glycol reacts with fatty acids to form propylene glycol fatty acid ester, which is mainly used as food emulsifier. propylene glycol is an excellent solvent for flavoring and coloring. Due to its low toxicity, it is used as a solvent for spices and food coloring in the food industry. propylene glycol is often used in the pharmaceutical industry as a solvent, softener and excipient for the manufacture of various ointments and ointments, and as a solvent for mixing agents, preservatives, ointments, vitamins and penicillin in the pharmaceutical industry. Because propylene glycol has good miscibility with various spices, it is also used as a solvent and softener for cosmetics. propylene glycol is also used as a tobacco humidifier, anti-mold agent, food processing equipment lubricating oil and food marking ink solvent. Aqueous solution of propylene glycol is an effective antifreeze agent. It is also used as tobacco wetting agent, anti-mildew agent, fruit ripening preservative, antifreeze and heat carrier.
