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. 
Zinc stearate is a white solid that repels water. 
Zinc stearate is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene) and chlorinated hydrocarbons when heated.
Zinc stearate is the most powerful mold release agent among all metal soaps. 
Zinc stearate 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.

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
Zinc stearate 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. In cosmetics, zinc stearate is a lubricant and thickening agent used to improve texture.

Zinc stearate 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.

Niche uses
Zinc stearate 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.

General description
The thermal decomposition of zinc stearate was studied.

Application
Zinc stearate was used as a reference compound to study the infrared spectra of a colloidal stearate-capped ZnO catalyst substrate for analysing gas adsorption on a colloidal stearate-capped zinc oxide (ZnO) surface. 
Zinc stearate was also used to prepare the sample suspension injection required for improving the therapeutic treatment for periodontitis.
Zinc Stearate is a hydrophobic organometallic zinc compound with numerous industrial uses including soaps and plastics. 

In comparison to other metallic stearates, zinc stearate has a low melting point (120°C) – meaning it spreads very evenly when heated.

Zinc stearate is mainly used in the plastics and rubber industries, where it is used as a lubricant and release or powdering agent.
 Zinc stearate functions as an acid scavenger and processing aid in certain polyolefin applications. In addition, it improves the abrasiveness of sandpapers, and acts as a matting agent in paints and coatings. In construction, powdered zinc stearate is utilized as hydrophobic agents for plasters.

Zinc stearates are available in various product forms - as powder or low-dust products – and as derivatives from animal or vegetable raw materials.

PRODUCT DETAILS & INFORMATION
Zinc Stearate is an oleochemical substance featuring a white, powdery appearance. Also known as zinc soap, Zinc Stearate has the ability to repel water and is insoluble in certain types of polar solvents. 
Zinc Stearate is formed by combining stearic acid with zinc oxide, the latter of which is an organic white-powder compound that is insoluble in water. While it does not produce a strong odor, Zinc Stearate powder does have a slight fatty acid scent.
There are a number of methods employed to manufacture Zinc Stearate. In addition to the direct method of combining stearic acid with zinc oxide, there is also an indirect method known as precipitation, which entails the formation of a solid from a liquid solution. 
The fusion method involves a high-shear process using tightly controlled pressure and temperature conditions.
Zinc Stearate offers a number of chemical properties that are invaluable from a manufacturing perspective. These include lubricity, compatibility and hydrophobicity (not attracted to water). It also features a “sharp” melting point, meaning it liquefies upon melting. The latter characteristic differentiates Zinc Stearate from other metallic stearate materials.
Zinc Stearate can be either veg or tallow-based — veg-based materials come from vegetable sources, while tallow-based materials are extracted from animal sources. Like all Metallic Stearates, Zinc Stearate has many industrial applications. The USP grade can be used in pharmaceutical, nutraceutical and cosmetic applications when used according to CFR 21 and FDA guidelines.

USES & APPLICATIONS
