This compound is a soap produced by reacting sodium stearate with magnesium salts, or via the treatment of magnesium oxide with stearic acid. It is also one of the two component compounds found in “soap scum”, which is the result of hard water being combined with ordinary soap. Industrially produced magnesium stearate is a white powder that is water insoluble with applications that tend to exploit its overall softness, insolubility in various solvents, and overall low toxicity. While its primary use is as a release agent/component or lubricant in manufacturing cosmetics, it has a wide variety of additional applications. Primarily, magnesium stearate is used as an anti-adherent agent in manufacturing medicinal tablets, capsules, and powders so that they do not stick to each other while in storage. It has similar applications in dry coating various surfaces in order to prevent adhesion, and it is also used to bind sugar in hard candies such as mints.
