Magnesium Stearate Description
Magnesium stearate is a salt containing two equivalents of stearate (the anion of stearic acid) and one magnesium cation (Mg2+). It melts at about 120℃, not soluble in water, and is generally considered safe for human consumption at levels below 2500 mg/kg per day. Magnesium stearate has good adhesion to the skin and good lubricity. It is used in powder products in cosmetics to improve adhesion and lubricity.
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.
Magnesium stearate has been widely used in the food industry as an emulsifier, binder and thickener, as well as an anticaking, lubricant, release, and antifoaming agent.
Magnesium stearate is commonly used as an inactive ingredient in the production of pharmaceutical tablets, capsules and powders.
Magnesium stearate is also widely used in the fields of plastic, mold-releasing agents for tablets, emulsifying agents of cosmetics. It also can conjugate with Ca soap as a stabilizer of PVC.
