Ethanol, also called alcohol, ethyl alcohol, and drinking alcohol, is the principal type of alcohol found in alcoholic beverages. It is a volatile, flammable, colorless liquid with a slight characteristic odor. Its chemical formula is C
2H
6O, which can be written also as CH
3-CH
2-OH or C
2H
5-OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH.

Ethanol is mostly produced by the fermentation of sugars by yeasts, or by petrochemical processes. It is an addictive psychoactive drug (indeed one of the oldest and most common recreational drugs), causing a characteristic intoxication ("drunkenness") and neurotoxicity when consumed in sufficient quantities. It is widely used as a solvent, as fuel, and as a for synthesis of other chemicals; as well as in many other minor uses.
