What is magnesium stearate?
Magnesium stearate, chemical formula for C36H70MgO4, molecular weight of 591.24, is a natural substance, is a white sand-free fine powder, unsafe call with the skin.
Insoluble in water, ethanol or ether, generally made use of as lubricating substance, anti-adhesion representative, circulation aid.
Magnesium stearate is specifically suitable for the granulation of oil and extract drugs, and the granules have great fluidness and also compressibility.
Magnesium stearate is made use of as a circulation help in direct pressing.
Magnesium stearate can additionally be utilized as filter aids, clarifiers and also frothing agents, as well as suspending representatives and thickeners for liquid preparations.

Prep work approach of magnesium stearate
15 phr of magnesium sulfate was liquified in 150 phr of water, heated up to 55 ℃, and gradually added to the prepared salt stearate option, the re-decomposition reaction was accomplished under stirring, as well as the magnesium stearate was precipitated as strong.
After the completion of the response, the clear liquid was divided, then cleaned with water, dehydrated by centrifugation as well as dried at 80-85 ℃ to get the completed item.

Application area of magnesium stearate
According to various application fields, magnesium stearate can be subdivided into food quality magnesium stearate, pharmaceutical grade magnesium stearate and industrial quality magnesium stearate; according to different dosage kinds of items, magnesium stearate can be subdivided right into powdered magnesium stearate and also flake magnesium stearate, among which powdered magnesium stearate is the mainstream product out there.

Powdered magnesium stearate is often made use of as anti-caking agent and also medication launching representative in the areas of day-to-day chemical items, medicine and food. with the fast development of downstream market, the market scale of powdered magnesium stearate will certainly remain to broaden.
1. Magnesium stearate is used as a warm stabilizer for PVC, along with basic materials for aesthetic flour, skin ointment as well as medical tablets (shaping agent, lube), for lubrication and also transparency in wood powder, and also for clear smoothing representative in paint market.
2. Widely used in food, medication, paint, plastic, rubber, fabric and more.
3. Magnesium stearate is a new type of medical excipient, which can be used as film coating product for strong preparation, thickener for colloidal fluid preparation, putting on hold agent and so on.
4. Used in cosmetics for powder items, can boost bond, lubricity, but additionally can be utilized as resources for pharmaceutical tablets.
