Magnesium stearate, also known as magnesium octadecanoate, is a fatty acid salt type anionic surfactant with a white fine powder appearance, a slight special odor, and a creamy feel. Soluble in hot aliphatic hydrocarbons, hot aromatic hydrocarbons, thermal grease, but insoluble in alcohol and water, the case of strong acid decomposition of stearic acid and the corresponding magnesium salt. Magnesium stearate has good adhesion to the skin, good lubricity, and it can be used in powder cosmetics in cosmetics to increase adhesion and lubricity.
Magnesium stearate can be used as a polyvinyl chloride heat stabilizer. Its stabilizing effect is similar to that of calcium stearate. It can be combined with zinc soap or calcium soap for food packaging materials, but its application is not extensive.
Magnesium stearate can also be used as a plastic product release agent, cosmetic powder, emollient ointment raw materials, pharmaceutical tablet powder molds, paint translucent flat agent.
The lab produces magnesium stearate by metathesis of sodium stearate and magnesium sulfate. It can also be refined by combining edible solid organic acids (stearic acid, palmitic acid) with magnesium oxide.
