ZN 78 (Zinc Stearate)

ZN 78 (Zinc stearate) is a white, finely powdered metal soap obtained by the reaction of stearic acid with zinc oxide or zinc salts. This water-insoluble substance, with a slight waxy odor, is widely used in the plastic, rubber, paint, cosmetics, and pharmaceutical industries due to its lubricant, mold release, and processing-enhancing properties. It also serves as a heat stabilizer in PVC production. Its water-repellent properties make it a preferred choice in formulations that require protection from moisture.
