Magnesium Stearate : Mg-St (C36H60MgO4)

Magnesium stearate is the magnesium salt of stearic acid, formed by the reaction of stearic acid with a magnesium source. It is a chemically stable, non-toxic compound widely used in industrial formulations. Magnesium stearate appears as a fine white powder that is insoluble in water. It is lightweight, hydrophobic, and exhibits excellent flowability and anti-caking characteristics.
