Magnesium stearate (MG2) is a white, water-insoluble powder. Its applications exploit its softness, insolubility in many solvents, and low toxicity. It is used as a release agent and as a component or lubricant in the production of pharmaceuticals and cosmetics. Magnesium stearate is produced by the reaction of sodium stearate with magnesium salts or by treating magnesium oxide with stearic acid. Magnesium Stearate gives our colour cosmetics both slip and adhesion. It is also used as a binding ingredient when pressing powders.
Typically 5–10% for loose powders. For creamy cosmetics and binding powders for pressing you'll need to use it at higher rates.
