Magnesium stearate is the chemical compound with the formula Mg(C18H35O2)2.
It is a soap, consisting of salt containing two equivalents of stearate (the anion of stearic acid) and one magnesium cation (Mg2+).
Magnesium stearate 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.

硬脂酸鎂是化學式為Mg(C18H35O2)2的化合物。
它是一種肥皂，由含有兩當量的硬脂酸酯(硬脂酸的陰離子)和一個鎂陽離子(Mg2 +)的鹽組成。
硬脂酸鎂是白色的水不溶性粉末。 它的應用充分利用了其柔軟性，在許多溶劑中的不溶性和低毒性。 它在藥物和化妝品生產中用作脫模劑和組分或潤滑劑。

Magnesium stearate is produced by the reaction of sodium stearate with magnesium salts or by treating magnesium oxide with stearic acid.
Some nutritional supplements specify that the sodium stearate used in manufacturing magnesium stearate is produced from vegetable-derived stearic acid.
硬脂酸鎂是通過硬脂酸鈉與鎂鹽的反應或通過用硬脂酸處理氧化鎂來生產的。
一些營養補充劑規定，用於製造硬脂酸鎂的硬脂酸鈉是由植物衍生的硬脂酸生產的。
