Ethylene Glycol (EG) is a colorless, odorless, sweet-tasting liquid used as an antifreeze and coolant in automotive and industrial applications.

It belongs to the glycol family, which are diols (two hydroxyl groups) known for their ability to lower freezing points and raise boiling points in solutions.

Common applications include heat transfer fluids, hydraulic fluids, and as a raw material in polyester production.
