Magnesium stearate is a white sand-free fine powder with a slight odor and a slippery feel when in contact with the skin. Its CAS NO. is: 557-04-0. It is insoluble in water, ethanol and ether, but is soluble in hot water and hot ethanol. When exposed to acid, it decomposes into stearic acid and the corresponding of magnesium salts.
Specification：
Magnesium stearate has a wide range of uses, the following are its main uses:
1. In the pharmaceutical industry, magnesium stearate can be used as a lubricant, anti-adhesive agent, and glidant. It is especially suitable for the granulation of oils and extract drugs. The granules produced have good fluidity and compressibility. Used as a flow aid in direct compression tablets, a filter aid, a clarifying agent and a dripping agent, as well as a suspending agent and thickener for liquid preparations.
2. In the fields of food, coatings, plastics, textiles and other fields, magnesium stearate powder can be used as a lubricant and glidant to increase the viscosity and lubricity of the product.
3. In cosmetics, magnesium stearate can be used in powdered cosmetics to increase the viscosity and lubricity of the product.
4. In the paint industry, magnesium stearate can be used as a transparent flattening agent.
