Trivial name (also glycol) for all glycol compounds; the correct name is ethylene glycol. These dihydric alcohols are often used in antifreeze and coolants. The derivative diethylene glycol gained an inglorious reputation in the Austrian wine scandal of 1985, because it was fraudulently added to simple wines to achieve a sweeter late harvest quality. See also under glycolic acid.
