Magnesium stearate: with a chemical formula of C36H70MgO4 and a molecular weight of 591.24, is an organic compound. It is a white, non-sandy fine powder that feels greasy when in contact with the skin. Insoluble in water, ethanol or ether, it is mainly used as lubricant, anti-sticking agent and glidant. It is especially suitable for the granulation of oils and extracts, and the granules produced have good fluidity and compressibility. Used as a glidant in direct compression.
They are white, fine powder, insoluble in water. When mixed with hot, strong mineral acids, they decomposed into stearic acid and corresponding magnesium salts.They are widely used as lubricants, slipping agents, heat-stabilizers, mould releasing agents and accelerants in plastic, machinery engineering, rubbers, paints and inks industry etc.
