polyethylene glycol

n. Abbr. PEG
Any of a family of high molecular weight liquids and waxes that are condensation polymers of ethylene glycol, are soluble in water and in many organic solvents, and are used in detergents, cosmetics, and pharmaceuticals and as emulsifiers, lubricants, and plasticizers.
