Magnesium stearate, chemical formula for C36H70MgO4, molecular weight of 591.24, is an organic compound, is a white sand-free fine powder, slippery call with the skin.
Insoluble in water, ethanol or ether, mainly made use of as lubricant, anti-adhesion representative, flow help.
Magnesium stearate is specifically ideal for the granulation of oil and extract medications, and also the granules have good fluidness and compressibility.
Magnesium stearate is utilized as a circulation help in direct pressing.
Magnesium stearate can also be used as filter aids, clarifiers and also foaming representatives, along with putting on hold representatives and thickeners for liquid prep work.

Preparation approach of magnesium stearate
15 phr of magnesium sulfate was liquified in 150 phr of water, warmed to 55 ℃, as well as gradually contributed to the prepared salt stearate solution, the re-decomposition response was executed under mixing, and the magnesium stearate was sped up as solid.
After the completion of the reaction, the clear liquid was divided, then cleaned with water, dehydrated by centrifugation and also dried out at 80-85 ℃ to obtain the finished product.

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

Powdered magnesium stearate is typically used as anti-caking agent and medication launching agent in the areas of day-to-day chemical products, medicine and food. with the quick growth of downstream market, the marketplace scale of powdered magnesium stearate will remain to increase.
1. Magnesium stearate is utilized as a heat stabilizer for PVC, as well as resources for cosmetic flour, skin ointment and clinical tablet computers (shaping agent, lube), for lubrication as well as openness in timber powder, as well as for clear smoothing representative in paint sector.
2. Commonly used in food, medicine, paint, plastic, rubber, fabric and more.
3. Magnesium stearate is a brand-new kind of medical excipient, which can be used as film finishing product for strong preparation, thickener for colloidal fluid preparation, putting on hold representative and so forth.
4. Made use of in cosmetics for powder products, can enhance adhesion, lubricity, yet also can be utilized as resources for pharmaceutical tablets.
