Description
Soft, fine, white, waxy powder. Zinc stearate normally occurs as a mixture of the zinc oxide with zinc salts of stearic and palmitic acids. It is used in cosmetic and lacquer as a flatting agent. It is also used as a lubricant on the surface of rubbers and as a release agent on plastic molds. Zinc stearate has also found uses as a waterproofing agent for concrete, rock wool, paper, and textiles.
