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.
