Why magnesium stearate is a fatty acid salt anionic surfactant?
What is magnesium stearate?
Magnesium stearate is a white, sand-free fine powder, which will have a smooth and delicate feeling when in contact with the skin. It can play a lubricating role in the body and improve the digestive ability of the stomach. Magnesium stearate has the effects of lubrication and flow aid and is mainly used to make lubricants, flow aids, etc. The particles made of magnesium stearate also have good fluidity and can be used as clarifiers, filter aids, and liquid thickeners.
Preparation of magnesium stearate
It is defined by the combination of magnesium oxide and edible solid mixed fatty acid (mainly stearic acid) or sodium stearate saponified by stearic acid and sodium hydroxide and then decomposed with magnesium sulfate to obtain magnesium stearate. Stearic acid and water are added to the reaction pot, heated to 85 ℃, stirred, and dissolved, and then sodium hydroxide solution preheated to 75 ℃ is slowly added. After the saponification reaction, the temperature is controlled at 7Chemicalbook2 ℃; slowly add magnesium sulfate solution preheated to 55 ℃. After double decomposition, centrifuge water, wash the filter cake with water until the sulfate radical meets the requirements, then dry it, dry it by airflow, and screen it to obtain the finished product. The yield of stearic acid is 100%. Raw material consumption (kg/t) stearic acid (industrial product) 960 sodium hydroxide (95%) 140 magnesium sulfate (98%) 410.
Chemical properties of magnesium stearate
Magnesium stearate is also known as magnesium octadecanoic. Chemical formula Mg (C18H35O2) 2. Molecular weight 591.27. White soft bright powder or lump. Industrial products contain a small amount of oleic acid and 7% magnesium oxide, making them odorless and tasteless. Slightly soluble in water, soluble in Chemicalbook hot ethanol solution. It is decomposed into stearic acid and corresponding magnesium salt when meeting strong acid. It is prepared by reacting molten stearic acid and magnesium oxide or sodium stearate solution and diluting magnesium sulfate solution. It is used as a varnish, Powder molding agent for tablets, stabilizer for plastic products, etc.
Price of magnesium stearate
Magnesium stearate particle size and purity will affect the product's price, and the purchase volume can also affect the cost of magnesium stearate. A large amount of large amount will be lower. The price of magnesium stearate can be found on our company's official website.
