Characters and
Uses:
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 come from many animal and vegetable fats
and oils.
It is a waxy
solid, and its chemical formula is CH3 (CH2)*6COOH. 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.
Usage:
Stearic
acid is useful as an ingredient in making candles, soaps, and
cosmetics and for softening rubber.
