Brief Overview
Stearic acid chemicals known as octadecanoic acid is one of the most common and useful types of saturated fatty acids found in combined form in natural animal and vegetable fats. It is a waxy white solid with a chemical formula of CH3(CH2)16CO2H and a molar mass of 284.48 g/mol. Esters and salts of stearic acid are known as stearate. Stearic Acid found commercially is a mixture of approximately equal amounts of stearic and palmitic acids and small amounts of oleic acid. Naturally stearic acid occurs as a mixed triglyceride, or fat, with other long-chain acids and as an ester of fatty alcohol. It is found more abundantly in animal fat than in vegetable fat.

Manufacturing process

The manufacturing of the triple-based commercial grade of stearic acid is conducted by compression method. The fat and oil are hydrolyzed in high pressure and temperature to produce chains of fatty acid and glycerol. The product is purified by washing and distillation before undergoing compression to remove oleic acid. The compression is done in several stages and each stage yields different purities. The triple-pressed method offers the highest purities of stearic acid in comparison with the double and single-pressed processes.

Emulsifying agent

Stearic acid emulsifying properties reduce water surface tension to prevent separation between oil and water. The compound helps to maintain the smooth and creamy texture of personal care products.

Cleansing

Stearic acid is considered as a reliable cleanser. The compound binds oil and water together that usually separates.
