Zinc stearate is a "zinc soap" that is widely used industrially. In this context, soap is used in its formal sense, a metal salt of a fatty acid: in this case stearic acid. It is a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene) and chlorinated hydrocarbons when heated. It is the most powerful mold release agent among all metal soaps. It contains no electrolyte and has a hydrophobic effect. Its main application areas are the plastics and rubber industry, where it is used as a releasing agent and lubricant which can be easily incorporated.[2]

Zinc carboxylates, e.g. basic zinc acetate, adopt complex formulas, and are not simply dicarboxylates of zinc. Instead the formula for most zinc carboxylates is Zn4O(O2CR)6, consisting of a Zn4O6+ core with carboxylate ligands spanning the edges.

Applications
It is widely used as a release agent for the production of many kinds of objects: rubber, polyurethane, polyester processing system, powder metallurgy. These applications exploit its "non-stick" properties.[2] In cosmetics, zinc stearate is a lubricant and thickening agent used to improve texture.[3]

It is an "activator" for accelerated rubber sulfur vulcanization. As discovered in the early days of vulcanization, zinc has a beneficial effect on the reaction of the sulfur with the polyolefin. The stearate is a form of zinc that is highly soluble in the nonpolar medium of the polyolefins.

Being lipophilic, it functions as a phase transfer catalyst for the saponification of fats.[2]

Niche uses
It is a component of some paints, imparting gloss. As a chief ingredient in "fanning powder", it is used by magicians performing card manipulation to decrease the friction between playing cards.

Zinc Stearate is a hydrophobic organometallic zinc compound with numerous industrial uses including soaps and plastics. Zinc Stearate is one of numerous organo-metallic compounds Organo-Metallic Packaging, Lab Quantity(also known as metalorganic, organo-inorganic and metallo-organic compounds) for uses requiring non-aqueous solubility such as recent solar energy and water treatment applications. Similar results can sometimes also be achieved with Nanoparticles and by thin film deposition.  Zinc Stearate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Additional technical, research and safety information is available.

Zinc stearate (C36 H70 O4 Zn) is a “zinc soap” widely used in industry, in the sense of the metallic “salt” of a fatty acid. It is a white solid that repels water. Zinc stearate is insoluble in polar solvents such as alcohol or ether but dissolves well when heated in aromatic solvents such as benzene. Among metallic soaps, Zinc stearate is the most powerful mold release agent. Zinc stearate does not contain an electrolyte and has a hydrophobic effect. Zinc stearate is mainly used in the plastics and rubber industry, as a mold release agent and easily incorporated lubricant1.

Zinc carboxylates, like zinc acetate, have complex formulas, and are not just zinc dicarboxylates. Indeed, the formula of most is in the form Zn4O (O2CR) 6, with a Zn4O6 + ring surrounded by carboxylate ligands.

Uses of Zinc Stearate
 Zinc Stearate is widely used as a mold release agent for the production of various objects, rubber, polyurethane, polyester, but also in metallurgy. These applications exploit its anti-adhesive properties1. For cosmetics, zinc stearate is a lubricant and thickener2.

Zinc Stearate is also used by magicians to reduce the friction between playing cards.

Insoluble in water, alcohol and ethers
Zinc stearate is extremely water resistant and has water repellent properties
It is a very effective release agent
Zinc stearate serves as a zinc supplement, which is beneficial for certain processes
ANTI DUST STEARATE: DUST-FREE
:

Cleaner product handling
Easier transport
Best dosage, no lumps, no sticky, etc.
Constant bulk density
Customized particle size
This stearate is perfect for applications where Zinc Stearate is dosed by pneumatic conveying systems. With the dust-free, the stearate does not clog the filters of the system and will remain in the granules, the pellets, the ingredients, etc.

It has another advantage which is that it results in more accurate dosages and better product recovery.
The addition of material by turning the big bags by hand or in open spaces is much cleaner because there is no dust.
