Alcohol
Chemical Formula:
Synonyms
ethanol,
ethyl alcohol,
SD alcohol 40-B
Description
Colorless flammable liquid
Uses
Alcohol is used as a fast drying solvent in many products, especially
cosmetics and hair sprays.
When the word
alcohol is used alone, it refers to
ethanol, the alcohol found in wine, beer, and distilled
spirits.
When used in products not licensed for drinking,
ethanol is usually
denatured. Such alcohols are called
denatured alcohol, or "specially denatured" alcohol. You will
often see "SD alcohol" mentioned on a label, sometimes followed
by a number and letter, such as "40-B". This is the designation
given by the U.S. Bureau of Alcohol, Tobacco, and Firearms to
the denaturing method used. For example, SD-40 is ethanol
denatured by adding tiny amounts of the bitterest tasting
substance known --
denatonium benzoate.
Other alcohols
There are a large number of alcohols besides ethanol. All of them
have the hydroxyl group OH attached to a carbon atom. The simplest
is
methanol:
Methanol has one carbon, ethanol has two, and there are two forms
of the alcohol with three carbons --
propanol
and
isopropanol.
