Zinc Stearate (C36H70O4Zn) or Zinc octadecanoate is the zinc salt of stearic acid, produced as a fine white hydrophobic powder. Known for its low solubility in water and strong hydrophobicity, it is universally valued as a mould release agent, lubricant, and processing aid. In plastics and rubber, it prevents sticking and enhances flow during moulding. In paints and coatings, it serves as a matting and thickening agent. In cosmetics, it provides texture enhancement and water repellency in powders and ointments. Also referred to as Octadecanoic acid, zinc salt – known by Zinc Stearate supplier and manufacturer. We are the leading, trusted Zinc Stearate supplier worldwide and in the United States, with reliable lead times and global supply capability.
