Technical Document

Brief Overview

Stearic acid, is present in high-fat sources from both plants and animals, and it belongs to the category of saturated fatty acids. Renowned for its positive health effects, it appears as a waxy white solid with a molar mass of 284.48 g/mol and a chemical formula of CH3(CH2)16CO2H. Naturally occurring in these fats are stearic, palmitic, and oleic acids, with the production of commercial stearic acid requiring nearly equal amounts of oleic and palmitic acids. Stearic acid is commonly found in nature either as an ester of fatty alcohol or as a mixed triglyceride with other long-chain acids. Notably, animal fats often contain a higher concentration of stearic acid compared to fats derived from plants.

 

Manufacturing Process

Fatty acids play a crucial role in stearic acid production, and the method depends on final product quality and raw material. Various protocols are used. Tallow and grease are common raw materials. The production involves two main steps:

a. Hydrolysis generates glycerin and fatty acids from raw ingredients (oil or fat), followed by the separation of the two products.

b. Separation includes the purification and separation of the fatty acid mixture in the second stage.
