Polyethylene glycol is short for PEG. Ethylene glycol is a polymeric compound formed by intermolecular dehydration condensation. The chemical formula HOCH2(CH2OCH2)nCH2OH. Where n is greater than 4. The average molecular weight is 200 ~ 7000. The number after the commercial PEG indicates the average molecular weight. For example, polyethylene glycol -400 indicates that the average molecular weight of polyethylene glycol is about 400.
Colorless viscous polyethylene glycol liquid
Colorless viscous liquid or white solid. Low toxicity! Soluble in water and many organic solvents, easily soluble in aromatic hydrocarbons, slightly soluble in fatty hydrocarbons. It does not hydrolyze for a long time, is stable to heat and does not react with many chemical reagents. Some metal salts are soluble in polyethylene glycol at about 100℃ and remain stable at room temperature. These metal salts include the chlorides of calcium, cobalt, copper, iron, magnesium, manganese, tin and zinc, potassium iodide and ethyl mercury. It can be used as plasticizer, softener, wetting agent, lubricant, solvent, adhesive, and can also be used as a spice and drug preparation.
