Zinc Stearate USP

Zinc stearate is a “zinc soap” that is widely used industrially. In this context, soap is used in its formal sense, a metal “salt” of a fatty acid. It is a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene) and chlorinated hydrocarbons when heated.


It is the most powerful mold release agent among all metal soaps. It is widely used as a release agent for the production of many kinds of objects: rubber, polyurethane, polyester processing system, powder metallurgy. These applications exploit its “non-stick” properties. In cosmetics, zinc stearate is a lubricant and thickening agent used to improve texture. Being lipophilic, it functions as a phase transfer catalyst for the saponification of fats
