What is Polyethylene Glycol CAS 25322-68-3?

Polyethylene glycol has different properties depending on its relative molecular weight, ranging from colorless and odorless viscous liquids to waxy solids. Those with a molecular weight of 200-600 are liquids at room temperature, while those with a molecular weight above 600 gradually become semi-solid. The properties also vary with the average molecular weight. From colorless and odorless viscous liquid to waxy solid.
