Stearic Acid (C18 50% - 54%)

Brief Overview

Widely recognized and beneficial, stearic acid, also known as octadecanoic acid, is a saturated fatty acid present in fats from both plant and animal sources with high fat content. With a molar mass of 284.48 g/mol and a chemical formula of CH3(CH2)16CO2H, it manifests as a waxy white solid. In its natural state, these fats contain oleic, palmitic, and stearic acids, and roughly equal parts of oleic and palmitic acids are essential for commercial stearic acid production. Stearic acid is commonly found in nature either as an ester of fatty alcohol or in mixed triglycerides with other long-chain acids. Notably, the concentration of stearic acid in animal fats is often higher than in plant-based fats.

Manufacturing Process

Fatty acids play a pivotal role in the production of stearic acid, with the manufacturing approach tailored to meet specific quality standards and the chosen raw materials. Various procedures are applied to align with these criteria. Tallow and grease stand out as the primary raw materials for synthesizing stearic acid. The production process involves two key stages:

1. Hydrolysis: Raw materials (oil or fat) undergo hydrolysis, resulting in the generation of glycerin and fatty acids. Following this, the two final products are separated.

2. Separation: The second stage encompasses the purification and separation of the fatty acid mixture, refining the stearic acid production process.

Paint Industry

Stearic acid stands out as a valuable wax modifier in the art of candlemaking. This non-toxic ingredient not only enhances the hardness and opacity of candles but also proves beneficial in maintaining the shape of freestanding candles, particularly during warmer seasons, while imparting a heightened whiteness. Moreover, it elevates the melting point and overall durability consistency of the candle. Beyond candlemaking, its stability and exceptional shaping abilities make it a preferred choice for crafting a diverse array of artistic and craft items.

Detergent Industry

Stearic acid assumes a pivotal role in the production of soaps and cosmetics, including formulations such as facewash, shampoo, beauty soaps, and shaving cream. Functioning as both a thickening and hardening agent, stearic acid imparts structural integrity, enabling the soap to maintain its desired form. Renowned for its potent cleansing properties, stearic acid additionally serves as an effective emulsifying agent, facilitating the binding of oil and water. This property finds application in facial cleansers, shampoos, and shaving creams, contributing to their formulation by imparting a desirable soft and creamy texture.

Fragrance and Flavoring Industry

In the food industry, stearic acid finds extensive application as both a binding agent and flavoring element, enhancing the taste and texture of a broad spectrum of food items. Its utilization spans the production of margarine, soft drinks, chewing gum, pastries, creamy spreads, artificial sweeteners, and various other products. The incorporation of stearic acid in these formulations is aimed at enriching the sensory attributes of the products and rendering them more visually appealing to consumers.
