Shandong propylene glycol industrial grade quality is good, use more economic Qingdao propylene glycol. 1,2-propanediol as a chemical agent, and water, ethanol and various organic solvents. Propylene glycol can be used as the raw material of unsaturated polyester resins. In cosmetics, toothpaste and soap with glycerin or sorbitol can be used with a wetting agent. The humidity in the hair dye used, the leveling effect of propylene glycol initiator, is also used as an antifreeze, also for cellophane, propylene glycol plasticizer and the pharmaceutical industry is an unsaturated polyester, an important raw material epoxy resin, polyurethane resin, and The amount in this area accounted for about 45% of the total consumption of propylene glycol, which is used extensively for unsaturated polyester surface coatings and reinforced plastics. The viscosity and moisture absorption of propylene glycol medical glycol, propylene glycol and non-toxic effect, which in the food, pharmaceutical and cosmetic industry is widely used as hygroscopic agent, antifreeze agents, lubricants and solvents. In the food industry, propylene glycol and propylene glycol fatty acid esters of fatty acids produced by the reaction, mainly for food emulsifier; Propylene glycol is an excellent solvent seasoning and coloring. Propylene glycol in the pharmaceutical industry for manufacturing various types of commonly used ointments, salves solvent, softener and excipients and the like, due to propylene glycol with various spices have good mutual solubility, and thus the solvent and the softening agent for cosmetics and the like. Propylene glycol is also used tobacco moisturizing agents, preservatives, food processing equipment, lubricants and food marking ink solvents. An aqueous solution of propylene glycol is effective cryoprotectant. Wei Connaught chemical, propylene glycol manufacturers _ _ propylene glycol role provided by Wei Connaught Chemical.
