Characters and Uses : White flaky
or lumpish. It is an important
chemical raw material and
additive, widely used in rubber,
plastics, cosmetics,
pharmaceuticals, chemical
auxiliary agent industries etc.
Stearic acid, also called
octadecanoic acid, is one of the
useful types of saturated fatty
acids that comes from many animal
and vegetable fats and oils. It
is a waxy solid, and its chemical
formula is CH3(CH2)16COOH. Its
name comes from the Greek word,
stear, which means tallow. Its
IUPAC name is octadecanoic acid.
Stearic acid is prepared by
treating animal fat with water at
a high pressure and temperature.
It can also be obtained from the
hydrogenation of vegetable oils.
Common stearic acid is actually a
mix of stearic acid and palmitic
acid, although purified stearic
acid is available separately.
Stearic acid is useful as an
ingredient in making candles,
soaps, and cosmestics and for
softening rubber.
