Magnesium stearate can also modify magnesium hydroxide as a surfactant. Magnesium hydroxide is a white powder, non-toxic, tasteless, and non-corrosive. It can be widely used in flame retardancy and smoke suppression of polymer materials such as polypropylene, polyvinyl chloride, and unsaturated resins.

They are white, fine powder, insoluble in water. When mixed with hot, strong mineral acids, they decomposed into stearic acid and corresponding magnesium salts.They are widely used as lubricants, slipping agents, heat-stabilizers, mould releasing agents and accelerants in plastic, machinery engineering, rubbers, paints and inks industry etc.

1. Pharmaceutical Industry: Magnesium stearate is often used as a diluent in the manufacture of medical tablets,capsules and powders,used for the lubricant,Glidante and anti-adhereute.

2. Food Industry: Magnesium stearate is also used to bind sugar in hard candies and is a common ingredient in baby formulas.

3.cosmetics and chemical industry: Desiccant powder, cosmetics, paint coatings.good lubrication dispersion stability additives plastic rubber.

4.Magnesium stearate is an excellent lubricating, dispersing and stabilizing aid for plastic rubber, a mold release agent for plastic products, a high temperature resistant powder molding agent for rubber products, and can also be used as a PVC heat stabilizer to increase the transparency or translucency of the product. Magnesium stearate can interact with hydrochloric acid decomposed from PVC to prevent decomposition. At the same time, magnesium stearate is also a good light stabilizer, which can inhibit the aging effect of ultraviolet rays on the film and prolong the service life of the agricultural film.
Researchers have also found that magnesium stearate has a flame-retardant effect in plastic rubber.
