Zinc stearate, also known as octadecanoic acid zinc salt, is a white solid. It is an important zinc soap, with a molecular weight of 594.58, and a molecular formula of C36H70O4Zn. It is insoluble in most organic solvents, such as ethanol, ether, and benzene.

Zinc stearate has a wide range of applications in the plastic, rubber, and paint industries. It is most commonly used as an anti-sticking agent in the manufacture of plastics, rubber, and paint. It is an effective lubricant and can also be used as an emulsifier or dispersant in paints and inks. In the plastics and rubber industries, zinc stearate is used as a processing and mold release agent. It helps to reduce friction between the plastic or rubber and the mold.

Zinc stearate is also used in the manufacture of cosmetics, soaps, and detergents. It is an excellent lubricant and can help to reduce the formation of foam. It is also used in the manufacture of pharmaceuticals and food additives.

Zinc stearate is produced by the reaction of zinc oxide with stearic acid. The reaction takes place under pressure and at high temperatures. It is a safe material and has a low toxicity, making it suitable for a wide range of industrial applications.
