Zinc stearate is a zinc soap that is known for repelling water. Zinc Stearate is commonly used as a release agent, heat stabilizer and lubricant in the plastics, polyolefin, polystyrene and rubber industry. Zinc Stearate is also used as a sanding additive in wood coatings (lacquers). In cosmetics, zinc stearate is a lubricant and thickening to improve texture. The insoluble salt is made of commercial stearic acid, a type of mild fatty acid that is used as an emollient and lubricant. It is often combined with zinc oxide. Zinc, on its own, is known to have antibacterial and antiviral properties.
Appearance of Zinc Stearate
Zinc stearate is a very fine, soft and colorless powder. It’s a high quality material with an exceptionally small particle size. It doesn’t have a strong odor, though it’s possible for there to be a slight fatty acid scent because of the long-chain fatty acids. Zinc stearates are soluble in aromatic compounds and chlorinated hydrocarbons when warmed, but they are insoluble in alcohol and ethers.
Best Applications for Zinc Stearate
Zinc stearate has many unique properties, which is why it can be used in a wide range of industries. For example, zinc stearate is used industrially as a release agent, lubricant and heat stabilizer for rubber and plastic manufacturers. It’s used as a sanding additive in wood coatings. Zinc stearate also acts as a lubricant and thickener in cosmetics. Thanks to its lubricating effects, water repellency, gelling capacity and non-stick texture, zinc stearate is highly versatile.
Below are the industries that benefit from using zinc stearates:
