Ethylene glycol
Ethylene glycol has a bitter, sweet taste and causes inebriation. The toxic effects of ingesting ethylene glycol occur because it is converted by the liver into 4 other chemicals that are much more toxic. The lethal dose of pure ethylene glycol is 1.4 ml/kg ( is lethal to a person) but is much less lethal if treated within an hour. (see Ethylene glycol poisoning).
