Sodium Stearyl Fumarate (CAS 4070-80-8)

Sodium stearyl fumarate, cataloged under CAS number 4070-80-8, is a sodium salt of stearyl fumaric acid, characterized by its application as a lubricant in various non-medical industries, particularly in food and cosmetics manufacturing. This compound is structurally unique due to the presence of a long stearyl chain and a fumarate group, which confer specific physicochemical properties such as hydrophobicity and an ability to interact with other molecular entities through non-covalent forces. In research contexts, sodium stearyl fumarate is often explored for its role in modifying the texture and stability of products. It acts by creating a barrier on the surface of particles, which can prevent adhesion and improve the free flow of powders, a property highly valued in the processing of powdered foods and in the production of personal care products. Furthermore, its efficacy as a lubricant allows for its use in studying the mechanics of solid-solid interactions in particulate systems. Researchers utilize this compound to understand and optimize the manufacturing processes where control over particle flow and reduction of friction are necessary. Additionally, sodium stearyl fumarate′s compatibility with various substances makes it a subject of study in the development of environmentally friendly lubricants and stabilizers that can perform effectively under a broad range of conditions.
