Magnesium stearate supplier

Magnesium stearate powder, with the chemical formula Mg(C18H35O2)2, is a salt compound of stearic acid (a long-chain fatty acid) and magnesium. It is an organic compound with a molecular weight of 591.24. It is a white, sand-free fine powder and feels smooth when in contact with the skin. Insoluble in water, ethanol or ether.

Magnesium stearate bulk is mainly used as lubricant, anti-sticking agent and glidant. It is especially suitable for granulating oils and extract drugs. The granules produced have good fluidity and compressibility. Used as a glidant in direct compression tableting. It can also be used as a filter aid, clarifying agent and foaming agent, as well as a suspending agent and thickener for liquid preparations.

How to synthesize magnesium stearate?

1. Preparation of sodium stearate: Dissolve 4.25 parts of sodium hydroxide in 50 parts of water, heat to 85°C and set aside. Put 25 parts of stearic acid into the reaction kettle, heat 500 parts of water, stir and dissolve, and adjust the temperature to 85 to 90°C. Slowly add the prepared sodium hydroxide solution to the stearic acid aqueous solution while stirring, maintain the temperature at 75-80°C, and react to the end point while stirring. The product sodium stearate liquid is kept warm for later use.

Preparation of Magnesium Stearate Powder function: Dissolve 15 parts of magnesium sulfate in 150 parts of water, raise the temperature to 55°C, and slowly add it to the prepared sodium stearate solution, perform a metathesis reaction under stirring, and the stearin generated by the reaction Magnesium acid precipitates as a solid. After the reaction is completed, let it stand to separate the clear liquid, then wash it with water, centrifuge and dehydrate, and dry it at 80-85°C to obtain the finished product.

2. Neutralize 46.6g of stearic acid with 164mL of 1mol/L sodium hydroxide solution to obtain 50g of magnesium stearate in supplements in 2L of water. The prepared sodium stearate solution was heated to 80°C, and a solution prepared by dissolving 20g magnesium chloride in 100mL water was added dropwise. After constant stirring, a white precipitate quickly precipitated. After cooling, filter out, wash with water until no chloride ions are present, and finally wash with ethanol. Place 10g of the product in a vacuum dryer with concentrated sulfuric acid for 4 weeks to obtain the product Mg(C18H35O2)2·2H2O. Dissolve the remaining product in benzene and heat under reflux for 20 minutes. Pour off the upper yellow liquid layer while hot and evaporate to dryness. The obtained solid can be recrystallized from benzene to obtain the product Mg(C18H35O2)2.
