ethylene glycol. (glÄ«'kÃ´l') A poisonous, syrupy, colorless alcohol used as an antifreeze in heating and cooling systems that use water. Ethylene glycol is chemically like ethanol but has two hydroxyl (OH) groups instead of one. Also called glycol. Chemical formula: C2H6O2.
Ethylene Glycol (EG) is still in use for aircraft de-icing in some parts of the world because it has a lower operational use temperature (LOUT) than Propylene Glycol (PG), but PG is more common because it is classified as non-toxic, unlike Ethylene Glycol.
