Polyethylene glycol is a kind of high polymer, the chemical formula is HO(CH2CH2O) NH, non-irritating, slightly bitter taste, with good water solubility, and many organic components have good compatibility.It has excellent lubricity, moisture retention,dispersion and adhesion Polyethylene glycol series PEG200 PEG400 PEG600 PEG800 Product performance: This series product non-toxic, without excitant, soluble in water ethanol and a variety of organic solvents, insoluble in most of the fatty hydrocarbon and ethyl ether .in accordance with different relative molecular mass and different nature. With the increase of molecular weight of the moisture absorption ability, and the corresponding lower solubility, and the frizzing point, relative density, flash point and viscosity increase.
