Technical Document

Brief Overview

Stearic acid, also known as octadecanoic acid, is a saturated fatty acid found in high-fat plant and animal sources. It appears as a waxy white solid with a molar mass of 284.48 g/mol and a chemical formula of CH3(CH2)16CO2H. Known for positive health effects, stearic acid is naturally present in fats alongside palmitic and oleic acids. Its production involves almost equal amounts of oleic and palmitic acids. Often occurring in nature as an ester of fatty alcohol or in mixed triglycerides, stearic acid is more concentrated in animal fats compared to plant-derived fats.


Manufacturing Process

In the production of stearic acid, fatty acids play a pivotal role, and the method is tailored to match the quality of the final product and the chosen raw material. Diverse protocols are employed, with tallow and grease being prevalent raw materials. The production process comprises two key steps:

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

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

Paint Industry

Stearic acid emerges as a valuable enhancer in the art of candlemaking. Not only does it boost the hardness and opacity of candles, but this safe additive also plays a crucial role in maintaining the shape of freestanding candles—especially in warmer conditions—while intensifying their brightness. Furthermore, stearic acid raises the melting point and overall consistency and durability of candles. Its remarkable stability and shaping attributes position it as the preferred choice for crafting a diverse array of artistic and creative objects.


Detergent Industry

Stearic acid is a crucial component in cosmetics and soaps, from face wash and shampoo to beauty soaps and shaving cream. It plays a vital role in thickening or hardening soap, ensuring its structural integrity. In addition to enhancing texture, stearic acid acts as a potent cleanser and emulsifying agent, binding water and oil harmoniously. This versatility makes it a key ingredient in face wash, shaving cream, face cleansers, and shampoos, imparting a smooth and creamy quality to these products.


Fragrance and Flavoring Industry

The food industry frequently uses stearic acid as a binder and flavoring ingredient to enhance the flavor and texture of a variety of food products. Among many other products, it is utilized in the production of margarine, soft drinks, chewing gum, pastry items, creamy spreads, and artificial sweeteners. Stearic acid is included in these formulations to improve the items' sensory aspects and increase their visual appeal to customers.
