    Definition condensation polymer of ethylene oxide and water with the general formula H(OCH 2CH 2) nOH, where n is the average number of repeating oxyethylene groups, typically from 4 to about 180 Reference "Chemicalland21.com, POLYETHYLENE GLYCOL (31.10.2019)"
    Comment The low molecular weight members from n=2 to n=4 are diethylene glycol, triethylene glycol and tetraethylene glycol respectively, which are produced as pure compounds. The low molecular weight compounds up to 700 are colourless, odourless viscous liquids with a freezing point from -10 C (diethylene gycol), while polymerized compounds with higher molecular weight than 1,000 are waxlike solids with melting point up to 67 C for n 180.
