polyethylene glycol

[¦päl·ē′eth·ə‚lēn ′glī‚kȯl]
(organic chemistry)
Any of a family of colorless, water-soluble liquids with molecular weights from 200 to 6000; soluble also in aromatic hydrocarbons (not aliphatics) and many organic solvents; used to make emulsifying agents and detergents, and as plasticizers, humectants, and water-soluble textile lubricants.
