Magnesium stearate, chemical formula for C36H70MgO4, molecular weight of 591.24, is a natural compound, is a white sand-free fine powder, slippery call with the skin.
Insoluble in water, ethanol or ether, generally used as lubricant, anti-adhesion representative, flow aid.
Magnesium stearate is especially suitable for the granulation of oil and extract drugs, and the granules have good fluidness and compressibility.
Magnesium stearate is made use of as a circulation aid in direct pressing.
Magnesium stearate can likewise be made use of as filter help, clarifiers and also lathering agents, along with suspending representatives and also thickeners for liquid preparations.

Prep work technique of magnesium stearate
15 phr of magnesium sulfate was liquified in 150 phr of water, heated to 55 ℃, and gradually contributed to the ready sodium stearate solution, the re-decomposition response was executed under stirring, and the magnesium stearate was precipitated as solid.
After the conclusion of the reaction, the clear fluid was divided, then cleaned with water, dehydrated by centrifugation and dried at 80-85 ℃ to get the finished product.

Application field of magnesium stearate
According to different application areas, magnesium stearate can be subdivided right into food quality magnesium stearate, pharmaceutical quality magnesium stearate as well as industrial grade magnesium stearate; according to various dose types of products, magnesium stearate can be subdivided into powdered magnesium stearate as well as flake magnesium stearate, amongst which powdered magnesium stearate is the mainstream product on the market.

Powdered magnesium stearate is usually used as anti-caking agent and also medicine releasing representative in the fields of daily chemical products, medication and also food. with the fast advancement of downstream market, the market range of powdered magnesium stearate will certainly continue to broaden.
1. Magnesium stearate is used as a warmth stabilizer for PVC, along with raw materials for cosmetic flour, skin lotion and also clinical tablet computers (forming agent, lube), for lubrication as well as openness in wood powder, as well as for transparent smoothing agent in paint industry.
2. Commonly utilized in food, medicine, paint, plastic, rubber, fabric and so forth.
3. Magnesium stearate is a brand-new type of medicinal excipient, which can be made use of as film finish material for strong prep work, thickener for colloidal liquid prep work, suspending representative and so on.
4. Used in cosmetics for powder products, can improve attachment, lubricity, yet likewise can be used as basic materials for pharmaceutical tablets.
