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 has a sweet taste and is often accidentally or intentionally ingested. Ethylene glycol is chemically broken down in the body into toxic compounds. It and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the kidneys.
