NINGBO INNO PHARMCHEM CO.,LTD. is a dedicated supplier of industrial chemicals, and understanding the fundamental zinc stearate chemical properties is key to leveraging its diverse applications. Zinc stearate, chemically known as zinc dioctadecanoate, is a metallic soap formed from stearic acid and zinc. Its unique physical and chemical characteristics make it indispensable in sectors ranging from plastics and rubber to coatings, cosmetics, and pharmaceuticals.

Physically, zinc stearate typically appears as a fine, white powder. It is insoluble in water but exhibits solubility in hot organic solvents such as ethanol, turpentine, and benzene. This solubility profile dictates its use in various solvent-based systems. A critical property is its melting point, which typically falls between 118-125°C, indicating its thermal stability within certain processing windows.

Chemically, zinc stearate acts as a lubricant, release agent, stabilizer, and dispersing agent. Its effectiveness stems from the interaction of the stearate chains and the zinc ion. In plastics, it reduces friction and prevents sticking to molds. In rubber, it facilitates processing and acts as an anti-stick agent. In paints, it can influence gloss and flow. Its non-toxic nature, particularly when derived from vegetable sources, allows for its use in applications that come into contact with food or skin, such as in some cosmetic and pharmaceutical products.

When considering sourcing zinc stearate, it is important to look for suppliers who can guarantee purity and consistent particle size, as these factors directly influence performance. Understanding the zinc stearate price in relation to quality and quantity is also a significant consideration for businesses.
