What is the efficacy and function of magnesium stearate?

What is Magnesium stearate?
Magnesium stearate is a kind of stearate, also known as magnesium octadecanoic, which has the dual characteristics of metal salt and stearic acid. Magnesium stearate is widely used in the pharmaceutical industry. It is an important lubricant for pharmaceutical tablets and can also be used as an additive for cosmetics and paint plastics. Food-grade magnesium stearate can be used as a food processing aid.

Production method of Magnesium stearate Powder
The production process of magnesium stearate is as follows:
 (1) adding 5 parts of magnesium hydroxide into a reaction kettle, heating and stirring uniformly to 40 DEG C, then adding 44 parts of 1841 stearic acid and 0.3 part of glacial acetic acid, and continuing to heat and stir for reaction, and controlling the reaction temperature to be at 95 DEG C at the highest; (2) When the material and water are obviously separated in the reaction kettle, the magnesium stearate can be obtained by separating the material from water after the reaction is completed, and the reaction time is 40? 60 minutes
The process of this technology is simple, and the wastewater generated in the reaction process can be reused after being treated in the sedimentation tank. Compared with zinc stearate by double decomposition method, the energy consumption is lower; The magnesium stearate obtained by this process has high transparency, low bulk density, fluffy products and excellent thermal stability. Compared with dry magnesium stearate and double decomposition magnesium stearate, the magnesium stearate has better performance and is widely used in industries.
Applications of Magnesium stearate Powder
1. This product is used as a heat stabilizer for PVC, as well as raw materials (excipients and lubricants) for cosmetic flour, emollient ointment, and pharmaceutical tablets; Used in wood flour to make it smooth, bright, and transparent; Paint industry as a transparent flatting agent, etc.
2. Widely used in food, medicine, coatings, plastics, rubber, textiles, etc.
3. It is a new pharmaceutical adjuvant that can be used as a film-forming coating material for solid preparations, thickener, and suspension for colloidal liquid preparations.
4. Cosmetics used in powder products can improve adhesion and lubricity and can also be used as raw materials for pharmaceutical tablets.
