trait
Magnesium steel is a white loose powder, odorless and tasteless, delicate and free of sand particles, with a light characteristic aroma.
Surfactant
Magnesium stearate, also known as magnesium octadecate, is a fatty acid salt type anionic surfactant. It appears as a white fine powder with a slight odor and a smooth texture. Soluble in hot fatty hydrocarbons, hot aromatic hydrocarbons, and hot oils, but insoluble in alcohols and water. When exposed to strong acids, it decomposes into stearic acid and corresponding magnesium salts. Magnesium stearate has good adhesion and lubricity to the skin, and is used in cosmetics for powder products to enhance adhesion and lubricity.
Magnesium stearate can be used as a heat stabilizer for polyvinyl chloride, with a stability effect similar to calcium stearate. It can be used in conjunction with zinc soap or calcium soap for food packaging materials, but its application is not widespread.
Magnesium stearate can also be used as a mold release agent for plastic products, a raw material for cosmetic powders, moisturizing ointments, a powder molding agent for pharmaceutical tablets, and a semi transparent smoothing agent for paints. The laboratory produces finished magnesium stearate through the double decomposition reaction of sodium stearate and magnesium sulfate. It can also be refined by combining a mixture of edible solid organic acids (stearic acid, palmitic acid) with magnesium oxide.
Magnesium stearate is a common flowing agent. Flow agents allow powders to flow through manufacturing machines during the production of certain supplements. Flow agents can also help pills better pass through the gastrointestinal system and increase the absorption of body components.

Product Packaging
Usage 1. Magnesium steam is used for making fragrance powder, cosmetics, and also as a drying agent for paints and false paints
Usage 2. Magnesium steel can be used as an anti caking agent; Release agent; Emulsifier.
Usage 3. Magnesium steel is used as a heat stabilizer for polyvinyl chloride, as well as a raw material for cosmetic flour, moisturizing ointment, and pharmaceutical tablets (shaping drugs, lubricants); Used in school wood powder to lubricate and make it shiny and transparent; The paint industry uses transparent leveling agents, etc. The metal soaps used as stabilizers for polyvinyl chloride are mainly composed of higher fatty acid salts of cadmium, barium, calcium, zinc, and magnesium, with stearic acid as the base and lauric acid as the salt.
The performance of metal soap stabilizers varies with the type of metal and acid groups, and the general rule is as follows: heat resistance: cadmium and zinc soaps have good initial heat resistance; Barium, calcium, magnesium, and strontium soaps have good long-term heat resistance, with lead soap in the middle. Weather resistance: cadmium, zinc, lead, barium, and tin soaps are better. Processability: Lead and cadmium soaps have good lubricity, but acid ions also have a significant impact on lubricity. For the same metal, aliphatic is better than aromatic, and the longer the molecular chain in the fatty acid group, the better the lubricity. Barium, calcium, magnesium and strontium soaps have poor lubricity, but gel has good melting ability.
Pressure separation: Barium, calcium, magnesium, and strontium soaps are prone to pressure separation, while zinc, cadmium, and lead soaps are less prone to pressure separation. Fatty acid soaps with longer molecular chains have heavier pressure separation and more severe frost spraying. Lead and cadmium soaps are highly toxic and have sulfur pollution. Calcium and zinc soaps are commonly used in non-toxic formulas; Barium and zinc soaps are commonly used in sulfur resistant formulas. Magnesium stearate can be considered non-toxic and is allowed to be used in products that come into contact with food in the United States, Germany, and Japan. However, its application as a heat stabilizer for polyvinyl chloride is not widespread.
This variety is included in the Chinese Pharmacopoeia and some other national pharmacopoeias, which specify the magnesium content, moisture, heavy metals, iron, sulfate, and chloride content.
Magnesium stearate is a new type of pharmaceutical excipient that can be used as a film-forming coating material for solid preparations, a thickener for colloidal liquid preparations, a suspension agent, etc.
Magnetic steel can be used as a stabilizer; lubricant; Pharmaceutical tablet raw materials
