Magnesium Stearate, also known as Magnesium Distearate, Magnesium Octadecenoate, and Octadecanoic Acid-Magnesium Salt, possesses the chemical formula C36H70MgO4 or Mg(C18H35O2)2. It appears as a fine, bulky, white odorless powder and is practically insoluble in water, ethanol. It can be produced on a lab scale by the reaction of sodium stearate with magnesium sulfate. When heated to decomposition it emits acrid smoke and toxic fumes. Chemically pure or Laboratory reagents are the two terms often used to describe Lab Grade chemicals. Lab Grade chemicals do not meet any accepted quality or purity requirements such as the ACS Grade, the USP Grade, and the FCC Grade, despite their acceptable purity. In the United States of America (USA), Lab Alley is selling its high-quality Magnesium Stearate, Lab Grade online Due to its high purity, this Lab Alley product is highly recommended for labs and commercial applications.
