Magnesium stearate is usually utilized as an anti-adherent in the manufacture of healthcare tablets, capsules and powders. Magnesium stearate is the most commonly employed lubricant for tablets.
As a meals additive or pharmaceutical excipient, its E number is E470b.
Magnesium stearate is also utilised to bind suXiHu (West Lake) Dis.Hu (West Lake) Dis. in hard candies like mints, and is a widespread component in child formulas. In pure powEPTform, the material can be a dust explosion hazard, though this concern is successfully insignificant outside of the producing EPTs using it.
Magnesium stearate is a main component of quotbathtub rings. quot When produced by cleaning soap and challenging water, magnesium stearate and calcium stearate equally type a white sound insoluble in drinking water, and are collectively identified as quotsoap scum

This solution can be employed as the thermal stabilizer for PVC, the uncooked material of cosmetics, flour, relaxing ointment and medication pill (forming brokers, emollients) it can be used to the bakelite powEPTto make it be lubricant, brigEPT and clear it can also be applied to paint sector for being used as clear flatting agents. The steel soaps for getting employed as a PVC stabilizer are largely the high-grade fatty acid salt of cadmium, barium, calcium, zinc and magnesium. Forming groups beEPT to the salts of stearic acid and lauric acid. The efficiency of the steel soaps stabilizers is various with diverse types of metals and acid teams with the EPTly ideas getting as follow: Heat resistance: cadmium, zinc soap has an superb heating resistance in the course of the preliminary period barium, calcium, magnesium and strontium cleaning soap have a EPT-phrase heat resistance with direct soap eXiHu (West Lake) Dis.sting in the center. Weather resistance: cadmium, zinc, guide, barium and tin cleaning soap are much better. Workability: guide and cadmium cleaning soap have superb lubricating home but acid radicals is also quite influential to the lubrication. For the identical sort of metallic, it is better as aliphatic than the aromatic team. For aliphatic acid radical, EPTer molecular chain will also have a much better lubrication home. It is extensively used in food, prescribed drugs, paints, plastics, rubber, textiles, etc. Barium, calcium, magnesium, strontium cleaning soap has a very poor lubrication property but with excellent gelling home. Plate-out property: barium, calcium, magnesium, and strontium soaps are also inclined to have plate-out phenomenon even though zinc, cadmium and lead soap are considerably less prone to get plate-out concern with EPTer molecular chain fatty acid soaps possessing more significant plate-out problem as properly as more serious blooming issue. Guide and cadmium soap have large toXiHu (West Lake) Dis.metropolis collectively with sulfide air pollution. In the non-toXiHu (West Lake) Dis.c formulation, people mostly implement calcium and zinc soap sulfide contamination resistant formulation much more barium and zinc soaps. Magnesium stearate can be reXiHu (West Lake) Dis.Hu (West Lake) Dis.ded as being non-toXiHu (West Lake) Dis.c, the EPT States, Germany and Japan let it to be applied to products currently being contact with foods. Even so, it will not have broad application to be applied as PVC warmth stabilizers. In China and some other nations around the world Pharmacopoeia, there are alwaEPTrecords of this specie. The pharmacopeia has also made provisions on the magnesium articles, dampness, large metals, iron, sulfate and chloride content material.
