Brief Overview

One of the most prevalent and beneficial forms of saturated fatty acids, octadecanoic acid (stearic acid) is found in combination in naturally occurring animal and vegetable fats. It is a waxy white solid with the chemical formula of CH3(CH2)16CO2H and molar mass of 284.48 g/mol. Stearate refers to stearic acid esters and salts. Commercial stearic acid is a blend of tiny amounts of oleic acid and roughly equal parts of palmitic and stearic acids. Stearic acid is found in nature as an ester of fatty alcohol and as a mixed triglyceride, or fat, with other long-chain acids. Compared to vegetable fat, animal fat contains a higher concentration of it.

Manufacturing Process


Fatty acids are used in the production of stearic acid. Depending on the type of raw material and the needed quality of stearic acid, there are various manufacturing procedures. The most frequent raw materials utilized in the manufacturing of stearic acid are tallow and grease. To produce stearic acids, there are two primary stages : 

 a. combination of fatty acids and glycerin are produced by hydrolyzing raw materials (fat or oil), which is followed by the separation of two products.

b. Fatty acid mixture purification and separation.
