Product Description

[Product name]: Magnesium stearate
[Molecular formula]: Mg[CH₃(CH₂)16COO]₂ 
[CAS NO.]: 557-04-0
[Properties]: It is a small light white powder, feels slippery, insoluble Water, ethanol and ether, soluble in hot water, hot ethanol, decomposed into stearic acid and the corresponding magnesium salt in case of acid. 
[Main uses]: This product is widely used in food, medicine, paint, plastic, rubber, textile and other industries, mainly as emulsifier, release agent, lubricant, stabilizer, accelerator, cosmetic base and so on. It can be used as a stabilizer and a lubricant for polyvinyl acetate, ABS resin, etc., and is used in combination with calcium soap and zinc soap for non-toxic products.
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. 

White, soft, bright powder. Industrial products contain a small amount of oleic acid and 7% magnesium oxide, odorless, odorless. Slightly soluble in water, soluble in hot ethanol solution

   Also known as magnesium octadecate, is a kind of fatty acid salt type anionic surfactant, white powder, slightly smelly, with a greasy feeling. Soluble in hot aliphatic hydrocarbon, hot aromatic hydrocarbon and hot grease, but insoluble in alcohol and water, decompose into stearic acid and corresponding magnesium salt in case of strong acid.
Magnesium stearate has good adhesion and lubricity to skin. It is used in powder products in cosmetics to improve adhesion and lubricity.

      Magnesium stearate can be used as a thermal stabilizer of polyvinyl chloride. Its stabilizing effect is similar to that of calcium stearate.

      Magnesium stearate can also be used as mold release agent for plastic products, cosmetic powder, raw material for skin cream, powder mold agent for pharmaceutical tablets, paint translucent leveling agent.

      Magnesium stearate is prepared in the laboratory by the double decomposition reaction of sodium stearate and magnesium sulfate, or by the combination of edible solid organic acids (stearic acid and palmitic acid) and magnesium oxide.
