Introduction：

Polyethylene glycol is referred to as "PEG". Ethylene glycol is a polymer compound formed by intermolecular dehydration condensation. Chemical formula HOCH2(CH2OCH2)nCH2OH. where n is greater than 4. The average molecular weight is 200~7000. The number after commercial polyethylene glycol indicates the average molecular weight. For example, polyethylene glycol-400 means that the average molecular weight of this commercial polyethylene glycol is about 400.
