Stearic Acid Specification

Stearic Acid, with the cas number 57-11-4, also called Octadecanoic Acid, one of the most common long-chain fatty acids, found in combined form in natural animal and vegetable fats. Commercial “stearic acid” is a mixture of approximately equal amounts of stearic and palmitic acids and small amounts of oleic acid. It is employed in the manufacture of candles, cosmetics, shaving soaps, lubricants, and pharmaceuticals.Stearic acid is prepared by treating these fats and oils with water at a high pressure and temperature (above 200 °C), leading to the hydrolysis of triglycerides. The resulting mixture is then distilled. Commercial stearic acid is often a mixture of stearic and palmitic acids, although purified stearic acid is available.

Uses of Stearic Acid: 
Generally applications of stearic acid exploit its bifunctional character, with a polar head group that can be attached to metal cations and a nonpolar chain that confers solubility in organic solvents. The combination leads to uses as a surfactant and softening agent. Stearic acid undergoes the typical reactions of saturated carboxylic acids, notably reduction to stearyl alcohol, and esterification with a range of alcohols.

Safety information of Stearic Acid:
When you are using this chemical, please be cautious about it as the following: Wear suitable gloves and eye/face protection; In case of contact with eyes, rinse immediately with plenty of water and seek medical advice; Keep away from sources of ignition - No smoking.
