Introduction：
Polyethylene glycol is a kind of polymer, its chemical formula is HO(CH2CH2O)nH, non-irritant, slightly bitter taste, good water solubility, and good compatibility with many organic components. Polyethylene glycol has excellent lubrication, humectancy, dispersion, and adhesion, and can be used as an antistatic agent softener, etc. It has a wide range of applications in cosmetics, pharmaceuticals, chemical fiber, rubber, plastics, paper making, paint, electroplating, pesticides, metal processing, and food processing industries.
Chemical Properties：
Depending on the molecular weight, Polyethylene glycol has different properties, ranging from colorless and odorless viscous liquid to waxy solid. Those with molecular weights 200-600 are liquid at room temperature, those with molecular weight above 600 gradually become semi-solid, and the properties vary with the average molecular weight. From colorless and odorless viscous liquid to waxy solid. As the molecular weight increases, its moisture absorption capacity decreases accordingly.
It is soluble in water, ethanol, and many other organic solvents. It has low vapor pressure and is stable to heat, acid, and alkali. It does not react with many chemicals. Good hygroscopicity, lubricity, and adhesion. Non-toxic, non-irritating. Average molecular weight 300, n=5～5.75, melting point -15～8℃, relative density 1.124～1.130. Average molecular weight 600, n=12～13, melting point 20～25℃, flash point 246℃, relative density 1.13(20℃). Average molecular weight 4000, n=70～85, melting point 53～56℃.
