99.8% Purity Magnesium Stearate Manufacturer Supply With Stock
Magnesium stearate Properties:
Magnesium stearate is a kind of fatty acid salt type anionic surfactant with its appearance being white powder with slight special smell and creamy feeling. It can be soluble in hot aliphatic hydrocarbons, hot arene and hot grease but insoluble in alcohol and water with being decomposed into stearic acid and corresponding magnesium salts in case of acid.
Magnesium stearate Product use:
Magnesium stearate has an excellent adhesion property to the skin with excellent lubrication property. It can be applied to powder products in cosmetics and can improve adhesion and lubrication.
Magnesium stearate can be used as PVC heating stabilizers with the stability performance being similar to calcium stearate and can be combined with zinc or calcium soaps for being applied to food packaging material but without very wide application.
Magnesium stearate can be used as a mold releasing agent of plastic products, face powder of cosmetics, the raw material of skin ointment, the powder molding tablet of pharmaceutical tablets and translucent flatting agent of paint.
Laboratory, through the replacement reaction of sodium stearate and magnesium sulfate, is able to get finished product of magnesium stearate and can also apply the combination reaction between edible solid organic acids (stearic acid palmitic acid) mixture and magnesium oxide compounds and further refinement to make it.
