Food Grade Stearic Acid/ Stearic Acid Powder CAS 57-11-4

Stearic acid , octadecanoic acid, simple structure: CH3(CH2)16COOH, produced by the hydrolysis of oils and fats, is mainly used to produce stearates. Each gram was dissolved in 21 ml of ethanol, 5 ml of benzene, 2 ml of chlorofo or 6 ml of carbon tetrachloride.

Function
Stearic acid 
stearic  and palmitic acids, although purifiedstearic acid is available.
Fats and oils rich in stearic acid are more abundant in animal fat (up to 30%) than in vegetable fat (typically <5%). The important exceptions are cocoa butter and shea butter, where the  stearic acid  content (as a triglyceride) is 28-45%.[10]
In terms of its biosynthesis, stearic acid is produced from carbohydrates via the fatty acid synthesis machinery wherein acetyl-CoA contributes two-carbon building blocks.

Application

In general, the 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, a notable one being reduction to stearyl alcohol, and esterification with a range of alcohols. This is used in a large range of manufactures, from simple to complex electronic devices.

1.Food industry:As raw material of lubricant, defoamer, food additives.
2.Cosmetics:Used to prepare cream, cold cream, foundation cream, shaving cream,etc.
3.Plastic processing: As plasticizer, lubricant, antistatic agent, antifogging agent,anti-aging agent and foaming agent used in PVC, PP, PE, etc..
4.Textile: As lubricant used in yarn, softening agent in mercerizing paste and waterproofing agent in textile.
5.Other area:Used to prepare polishing paste, metal flotation agent, paint smoothing agent, stencil polishing agent,etc.
