Technical Document

Brief Overview

Popular and advantageous, stearic acid (also known as octadecanoic acid) is a saturated fatty acid that can be found in fats derived from plants and animals that are also high in fat content. With a molar mass of 284.48 g/mol and a chemical formula of CH3(CH2)16CO2H, it is a waxy white solid. These fats are composed of the acids oleic, palmitic, and stearic in their natural state; roughly equal parts of oleic and palmitic acids are required to create commercial stearic acid. Stearic acid is frequently found in nature as an ester of fatty alcohol or in mixed triglycerides with other long-chain acids. It is said that the concentration of stearic acid in animal fats is frequently higher than in vegetarian fats.

Manufacturing Process

Fatty acids play a crucial role in the manufacturing of stearic acid, and the approach employed in this process is contingent on both the quality specifications for the final product and the chosen raw material. Different procedures are implemented in alignment with these criteria. Tallow and grease are the predominant raw materials utilized for the synthesis of stearic acid. The production process comprises two primary steps:

a. Hydrolysis: Raw ingredients (oil or fat) undergo hydrolysis to generate glycerin and fatty acids. Subsequently, the two final products are separated.

b. Separation: The second stage involves the purification and separation of the fatty acid mixture.

Paint Industry

In the art of candlemaking, stearic acid proves to be a valuable wax enhancer. In addition to increasing the hardness and opacity of candles, this safe additive enhances the brightness of freestanding candles and aids in maintaining their shape, particularly in warmer conditions. Stearic acid also contributes to the improvement of the melting point, consistency, and overall durability of candles. Due to its solidifying and shaping characteristics, it is a preferred choice for crafting a diverse array of artistic and creative products.


Detergent Industry

Stearic acid is used in the manufacture of soaps and cosmetics, such as face wash, shampoo, beauty soaps, and shaving cream. The goal is to make the soap thicker or harder so that its structural integrity is maintained. The binds between water and oil can be happened because stearic acid so the products remain creamy and smooth. It is also a powerful emulsifier and cleanser. To maximize its emulsifying and cleaning properties, this ingredient is commonly added to shampoos, face cleansers, and shaving creams.


Fragrance and Flavoring Industry

Stearic acid is widely used in the food industry as a binder and flavoring component to improve the flavor and texture of a wide range of food items. It is used in the manufacturing of margarine, soft drinks, chewing gum, pastry goods, creamy spreads, and artificial sweeteners, among many other things. These formulations use stearic acid in an attempt to enhance the sensory qualities of the products and make them more aesthetically pleasing to consumers.
