PEG is short for polyethylene glycol.
A polymer compound formed by dehydration and condensation of glycol between molecules.
The chemical formula is HOCH2(CH2OCH2), nCH2OH.Where n is greater than 4.
The average molecular weight is 200 ~ 7000.
The figure after commercial polyethylene glycol represents the average molecular weight.For example,
polyethylene glycol -400 indicates that the average molecular weight of the commercial polyethylene glycol is
about 400.A colorless viscous liquid or white solid.Low toxicity.
Soluble in water and many organic solvents, easily soluble in aromatic hydrocarbons, slightly soluble in aliphatic
hydrocarbons.It does not hydrolyze, is thermostable and does not react with many chemical reagents.
