Ethanol is used as the alcohol in beverages, a topical antiseptic and disinfectant (including hand sanitizers), a solvent and preservative in pharmaceuticals and laboratories, and an industrial feedstock for chemicals. It’s also used as a biofuel or fuel additive and in personal care products and tinctures. In high concentrations or amounts, ethanol is toxic if ingested or absorbed.

The chemical formula of ethanol is C2H5OH, commonly written as CH3CH2OH. It consists of two carbon atoms bonded in an ethyl group (CH3–CH2) with a terminal hydroxyl (–OH) group, classifying it as a primary alcohol. Its molecular formula is C2H6O, giving a molar mass of about 46.07 g·mol−1.

Ethanol (ethyl alcohol) is the specific alcohol found in alcoholic drinks. Chemically, “alcohol” denotes a class of compounds with an −OH group, so ethanol is one member of that class. Ethanol is used as a solvent, fuel and antiseptic and causes intoxication, dependence and organ damage at high doses. Other alcohols (e.g., methanol, isopropanol) are more toxic and unsafe to drink.

Ethanol (alcohol) is a psychoactive toxin: small amounts may relax people, but it harms health. Metabolite acetaldehyde is carcinogenic; alcohol raises risks of liver disease, several cancers, addiction, heart problems, injuries and pregnancy harm. Any benefits are uncertain and limited; for some people even low intake increases cancer risk. Limiting or avoiding alcohol is the safest option for most.

Yes. Ethanol is dose‑dependent toxic: small amounts are metabolized, but acute high doses cause intoxication, respiratory depression, coma and can be fatal; chronic use raises risk of liver disease, pancreatitis, cancer, cognitive decline and addiction. Vulnerable people (pregnant persons, children, those with liver disease or on certain medicines) are harmed at lower exposures, and even regular moderate use carries risks.

Ethanol occurs naturally in some foods and is used as a solvent or preservative. In the small amounts typically present in food and beverages it is considered safe for most healthy adults. Harm arises from high doses or long-term use (intoxication, liver damage, higher cancer risk). Pregnant people, children, those with liver disease or on interacting medicines should avoid even small amounts.
