Zinc Stearate IP
Abstract:
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.
Use/Application:
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
