Ethanol : Description and use

Description

Ethanol, or ethyl alcohol (or quite simply, alcohol), is a colourless, volatile and flammable liquid which is miscible with water in all proportions. It is a psychoactive drug, and one of the oldest recreational drugs, which comes in the form of alcoholic drinks. Ethanol is used in the agri-food industry (mainly to produce spirits), in perfume making, in galenical pharmacy (as a solvent) and as a biofuel (bioethanol). it is also used in alcohol thermometers.
It is a colourless liquid with a characteristic odour.

Flammability: Ethyl alcohol is a readily flammable liquid which can form an explosive mixture with air. The vapours can spread and cause a flashback. It is therefore important to work away from sources of sparks or flames.

USE

Ethanol or ethyl alcohol is mainly used:

  • as a raw material in the synthesis of chemical products
  • as a solvent in laboratories, and in the following industries: paint, varnish, ink, plastic materials, adhesive, cosmetic, pharmaceutical products
  • in the manufacture of cleaning products and insecticides
  • as a disinfectant

It is a base component in alcoholic drinks such as: wine and cider (10 to 13%), beer (0.5 to 7%) and spirits (40 to 50%). When it is not used for food and beverage purposes, denaturant substances are added to make it unfit for consumption. These substances include, but are not limited to: methanol, ethyl acetate, methyl isobutyl ketone, heptane or kerosene. Denaturants are governed by a federal law on excise: Denatured Alcohol Regulation (art. 125.1).
