Zinc stearate（Cat No.:R071314）is a white, fine, hydrophobic powder composed of zinc and stearic acid. It is widely used as a lubricant, release agent, and anti-caking additive in plastics, rubber, and cosmetics manufacturing. In the pharmaceutical industry, it functions as a flow agent in tablet production. Known for its low toxicity and excellent water repellency, zinc stearate improves surface texture and prevents materials from sticking to molds or machinery. Though generally safe, it should be handled in well-ventilated areas to avoid inhaling dust during large-scale processing or industrial applications.
