Zinc Stearate- Applications, Properties, Sources, And Toxicity

This article will cover the Characteristics of Zinc Stearate. It will discuss its applications, properties, sources, and toxicity. It will also give some background information on its use in the food industry. You can also learn more about this mineral by reading our other articles.


Zinc stearate is an additive used in the manufacture of many products. Its use in various industries ranges from food and beverages to plastics. It is also used as a release coating agent and as an activator in sulfur-vulcanized rubbers. Its unique crystal structure makes it an effective aid in a variety of processes and does not produce foam or affect viscosity. This chemical is produced through the reaction of stearic acid with calcium hydroxide. It is used as a release coating agent for plastics and rubbers, an activator for the vulcanization of rubbers, and as a flattening agent in nitrocellulose varnishes.


Zinc stearate is an insoluble white solid whose properties make it an excellent lubricant and mold release agent. It is a widely used release agent and lubricant in the plastics and rubber industries. Although it has little polar or aromatic cation affinity, zinc stearate is highly hydrophobic, which gives it a non-stick and water-repelling effect.


Zinc Stearate is a naturally occurring zinc compound with multiple industrial applications. It functions as a thickening agent, emulsifier, and release agent, making it an essential component in many industries. The material can be found in a variety of forms but is most commonly used as powder. It is white and has a faint characteristic odor. It is non-toxic and is used in a wide variety of products, including food, paint, and cosmetics.


The toxicity of zinc stearate has been determined in several studies. The EPA evaluated the scientific data available and determined its validity, completeness, and reliability. It also assessed the relationship of available information to the human risk and the variability of the sensitivities of major identifiable subgroups of consumers. These findings are based on studies involving human and animal subjects. These studies indicate the acute toxicity of zinc stearate.


Despite its chemical properties, zinc stearate is not soluble in polar solvents, but it does dissolve easily in aromatic compounds such as chlorinated hydrocarbons. This is why it has a wide range of applications in the rubber industry. The metal is used in rubber as a softening agent, lubricant, textile lighting agent, PVC stabilizer, and release agent.
