Ethylene glycol is an organic compound with the formula (CH₂OH)₂. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweet-tasting, viscous liquid.

Mono-ethylene glycol – or MEG – is a vital ingredient for the production of polyester fibres and film, polyethylene terephthalate (PET) resins and engine coolants. End uses for MEG range from clothing and other textiles, through packaging to kitchenware, engine coolants and antifreeze.

Ethylene glycol is a chemical commonly used in many commercial and industrial applications including antifreeze and coolant. Ethylene glycol helps keep your car’s engine from freezing in the winter and acts as a coolant to reduce overheating in the summer.
