Technical Document

Brief Overview

Octadecanoic acid, a synonym for stearic acid, is a form of saturated fatty acid that is found in high fat plant and animal sources. It is widely known for having many beneficial health effects. It exists as a waxy white solid with a molar mass of 284.48 g/mol and a chemical formula of CH3(CH2)16CO2H. These fats naturally contain oleic, palmitic, and stearic acids; almost equal amounts of oleic and palmitic acids are necessary for the production of commercial stearic acid. Commonly, stearic acid can be found in nature as a mixed triglyceride that includes other long-chain acids or as an ester of fatty alcohol. Notably, in comparison to fats derived from plants, animal fats frequently have a higher stearic acid content.

Manufacturing Process

Stearic acid is synthesized primarily from fatty acids, where the production process is tailored to match certain quality requirements and selected raw materials. Different protocols are used in order to comply with these requirements. The two main source materials that are commonly utilized to synthesize stearic acid are tallow and grease. There are two primary steps in the production process:

a. Hydrolysis: Glycerin and fatty acids are produced when raw materials (oil or fat) are processed by hydrolysis. The two final products are then separated.

b. Separation: The fatty acid mixture's purification and separation refine the stearic acid.

Paint Industry

Stearic acid is a beneficial wax modifier in the candlemaking process. This non-toxic component creates candles with brighter white look while also enhancing their durability and opacity. Additionally, it improves the shape-holding of freestanding candles, especially in the warmer months. It additionally improves the melting point and general endurance uniformity of the candle. In addition to candlemaking, its exceptional shape properties combined with stability make it a highly sought-after material for a variety of creative and craft applications.

Detergent Industry

In the manufacturing of soap and cosmetic products like face wash, shampoo, beauty soaps, and shaving cream, stearic acid plays a vital role. Its inclusion aids in maintaining the structural integrity of soap by either thickening or hardening it. Stearic acid is integral to face cleansers, shampoos, and shaving creams due to its dual functionality as a potent cleanser and an effective emulsifying agent. This dual role enables the seamless binding of oil and water, resulting in products characterized by a silky-smooth and creamy texture.

Fragrance and Flavoring Industry

Stearic acid is widely utilized in the food industry, acting as a multifunctional additive with roles as a flavoring agent and binder. Its diverse applications encompass improving the taste and texture of various products such as margarine, creamy spreads, chewing gums, bakery goods, dietary supplements, soft drinks, and artificial sweeteners. The deliberate inclusion of stearic acid in these formulations aims to enhance sensory qualities, resulting in visually appealing products for consumers.
