Chemical Name: Zinc Stearate
Molecular Formula:C36H70O4Zn
Molecular Weight: 632.33
Cas No.: 557-05-1
Product Description
Zinc Stearate is a fine, white, hydrophobic powder with a slight fatty acid odor. It is insoluble in water, alcohol, and ether, but disperses in aromatic hydrocarbons and chlorinated solvents when heated. Produced by reacting stearic acid with zinc oxide, it is classified as a zinc soap—an organic metal salt of a fatty acid.
