Zinc stearate (CAS 557-05-1)

Zinc stearate, a white, powdery metal salt resulting from the combination of zinc and stearic acid, finds broad application in numerous industries like cosmetics, plastics, paints, and rubber.This versatile, eco-friendly compound boasts a range of advantageous properties, including lubrication, water resistance, corrosion resistance, and thermal stability. Moreover, it serves as an emulsifier, thickener, and stabilizer in various applications. In the realm of scientific research, zinc stearate′s multiple benefits make it a sought-after ingredient. Within laboratories, it acts as a lubricant for equipment, a stabilizer during chemical reactions, and an emulsifier for aqueous solutions. In the world of paints and coatings, it functions as a dispersant, while in metalworking fluids, it excels as a corrosion inhibitor. While the precise mechanism of action remains somewhat elusive, the prevailing belief is that zinc stearate′s zinc ions interact with the fatty acids of stearic acid, forming a protective layer on the treated material′s surface. This protective barrier effectively wards off water, preventing corrosion. Furthermore, the zinc ions are thought to engage with other components, such as proteins and carbohydrates, creating a safeguarding film that combats oxidation and degradation. Zinc stearate stands as a prized substance, cherished for its diverse applications and the valuable properties it lends across various fields of science and industry.
