Manufacturer 557-04-0 best price Magnesium stearate good supplier

Magnesium stearate(light) Magnesium stearate(light) project Index chemical formula Mg[C17H35COO]2 appearance white powder, no obvious mechanical impurities. Standard specification Q/CJYF.7-2001 magnesium content,% 6.5~7.7 melting point, ℃ is greater than or equal to 120 free fatty acid (based on stearic acid),% less than or equal to 3.0 heating loss,% less than or equal to 3.0 fineness (through 0.075mm sieve),%≥ 99.0.

magnesium stearate, also known as magnesium stearate, is a fatty acid salt Type Anionic Surfactant with white fine powder appearance, the patient has mild odor and a smooth feeling. Soluble in thermal aliphatic hydrocarbons, thermal aromatic hydrocarbons, thermal oils and fats, but insoluble in alcohol and water, in case of strong acid decomposition into stearic acid and the corresponding magnesium salts. Magnesium stearate has good adhesion to the skin, good lubricity, in cosmetics for powder products, can improve adhesion, lubrication.
magnesium stearate can be used as a heat stabilizer for polyvinyl chloride, and its stabilizing effect is similar to that of calcium stearate. It can be used in food packaging materials with zinc soap or calcium soap, but it is not widely used.
magnesium stearate can also be used as a mold release agent for plastic products, a raw material for cosmetic powder, a moisturizing ointment, a powder molding agent for pharmaceutical tablets, and a translucent leveling agent for paint.
The finished product of magnesium stearate was prepared by metathesis reaction of sodium stearate and magnesium sulfate in the laboratory. It can also be refined from the mixture of food-grade solid organic acid (stearic acid, palmitic acid) and magnesium oxide.

sodium stearate is obtained by saponification of stearic acid with sodium hydroxide and then metathesis with magnesium sulfate to obtain magnesium stearate. Stearic acid and water were added to the reaction Pan, heated to 85 °c, stirred and dissolved, and then sodium hydroxide solution preheated to 75 °c was slowly added. After completion of the saponification reaction, the temperature was controlled at 72 °c, and a magnesium sulfate solution preheated to 55 °c was slowly added with stirring. After the double decomposition, the filter cake was washed with water until the sulfate group met the requirements, and then dried, air dried and sieved to obtain the finished product. The yield of p-stearic acid was 100%. Raw material consumption (kg/t) stearic acid (industrial) 960 sodium hydroxide (95%) 140 magnesium sulfate (98%) 410
mixed fatty acids from magnesium oxide and food-grade solid (mainly stearic acid) the compound was refined.
