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.
Packing: In net 25kg polywoven bags
Physical Property:Stearic Acid is Shaped like Lump, flake; Saturated fatty acid mainly with C16 and C18,
white flake solid at ambient temperature, not dissolved in water, slightly dissolved in
benzene and carbon bisulfide, and easily dissolved in hot alcohol. No smell no poison.
It has the general chemical properties of organic carboxylic acid.
Applications:
Stearic Acid is Widely used in curing agent, plastic heat stabilizer, wetting agent,
textile softener, chemical fiber oil, antistatic agent, edible emulsifier; also used in
cosmetics, detergent and the intermediates of various surfactants, etc.
