What is magnesium stearate? Magnesium stearate, chemical formula for C36H70MgO4, molecular weight of 591.24, is an organic compound, is a white sand-free fine powder, slippery contact with the skin. Insoluble in water, ethanol or ether, mainly used as lubricant, anti-adhesion agent, flow aid. Magnesium stearate is especially suitable for the granulation of oil and extract drugs, and the granules have good fluidity and compressibility. Magnesium stearate is used as a flow aid in direct pressing. Magnesium stearatecan also be used as filter aids, clarifiers and foaming agents, as well as suspending agents and thickeners for liquid preparations.
Preparation method of magnesium stearate 15 phr of magnesium sulfate was dissolved in 150 phr of water, heated to 55 ℃, and slowly added to the prepared sodium stearate solution, the re-decomposition reaction was carried out under stirring, and the magnesium stearate was precipitated as solid. After the completion of the reaction, the clear liquid was separated, then washed with water, dehydrated by centrifugation and dried at 80-85 ℃ to get the finished product.
Application field of magnesium stearate According to different application fields, magnesium stearate can be subdivided into food grade magnesium stearate, pharmaceutical grade magnesium stearate and industrial grade magnesium stearate; according to different dosage forms of products, magnesium stearate can be subdivided into powdered magnesium stearate and flake magnesium stearate, among which powdered magnesium stearate is the mainstream product in the market.
Powdered magnesium stearate is often used as anti-caking agent and drug releasing agent in the fields of daily chemical products, medicine and food. with the rapid development of downstream market, the market scale of powdered magnesium stearate will continue to expand. 1. Magnesium stearate is used as a heat stabilizer for PVC, as well as raw materials for cosmetic flour, skin ointment and medical tablets (shaping agent, lubricant), for lubrication and transparency in wood powder, and for transparent smoothing agent in paint industry. 2.Widely used in food, medicine, paint, plastic, rubber, textile and so on. 3. Magnesium stearate is a new type of medicinal excipient, which can be used as film coating material for solid preparation, thickener for colloidal liquid preparation, suspending agent and so on. 4. Used in cosmetics for powder products, can improve adhesion, lubricity, but also can be used as raw materials for pharmaceutical tablets.
