How Magnesium Stearate is used in the Food and Pharmaceutical Industries
What is magnesium stearate?
Magnesium Stearate Powder is a white sand-free fine powder, insoluble in water, ethanol or ether. Magnesium stearate in bulk is often used as lubricant, anti-sticking agent and glidant, especially in oils, granulation of extract drugs, the granules produced have good fluidity and compressibility.

So, what is magnesium stearate used for?(magnesium stearate function)
As a common chemical substance, magnesium stearate is widely used in the fields of medicine, food and cosmetics. The following is an introduction to the functions of magnesium stearate:
1. Magnesium stearate in medicine: Magnesium stearate pure powder has good fluidity and compressibility, which can help the pharmaceutical raw materials to be mixed evenly, improve the stability of the tablets, and extend the shelf life of the medicine.
2. Lubricant: Magnesium stearate is used to reduce friction and adhesion between powder or granular preparations. By adding magnesium stearate, the friction resistance during the preparation process can be effectively reduced and the processability and fluidity of the product can be improved.
3. Stabilizers and lubricants in cosmetics: Natural magnesium stearate can help maintain the stability of the texture of cosmetics, provide cosmetics with a smooth touch, and enhance the ductility and spreadability of cosmetics.
4. Emulsifiers and stabilizers in the food industry: Pure magnesium stearate is used as an emulsifier and stabilizer for dairy products, chocolate and condiments. It can promote the mixing and stabilization between fat and water and prevent food stratification. and precipitation, improving the texture and taste of food.

2. Oil absorption: Magnesium stearate in bulk has strong oil absorption, which can absorb excess sebum from the skin, help control oil secretion, and reduce pore clogging.
3. Stabilizer: Magnesium stearate supplements can help combine water and oil, maintain the even dispersion of ingredients in the lotion, prevent separation or precipitation, and extend the shelf life of cosmetics.
4. Antibacterial effect: Magnesium stearate can inhibit the growth of bacteria and fungi, and has a certain alleviation effect on skin acne or other skin infections.

Magnesium stearate is classified as GRAS, and in a report from the National Center for Biotechnology, 2,500 milligrams of magnesium stearate per kilogram of body weight is considered safe, meaning a person weighing about 150 pounds can consume 170,000 milligrams per day. Magnesium stearate and is safe.
Magnesium Benefits:
• Magnesium supports heart function in the body
• Magnesium powder supports muscle growth
• Magnesium can help relieve negative emotions such as anxiety and depression

1. Nuts and seeds: Many nuts and seeds contain magnesium stearate, such as almonds, walnuts, pumpkin seeds, sesame seeds, and sunflower seeds.
2. Vegetables: Most vegetables contain a certain amount of magnesium and magnesium stearate, especially green leafy vegetables, such as spinach, rape, and lettuce. Other vegetables rich in magnesium stearate include tofu, beans, and potatoes. and tomatoes, etc.
3. Animal foods: Magnesium stearate is also found in beef, pork, chicken, fish and shellfish, but the content is relatively low.
What is the difference between magnesium stearate and magnesium phosphatidate?
Magnesium stearate and magnesium phosphatidate are two different compounds with some differences in structure and properties:
1. Chemical structure:
Magnesium stearate: Magnesium stearate is a salt composed of stearic acid and magnesium ions. Stearic acid is a saturated fatty acid with 18 carbon atoms.
Magnesium phosphatidate: Magnesium phosphatidate is a salt composed of phosphatidic acid (Phosphoric acid) and magnesium ions. It is a phosphorus-containing organic acid.
2. Physical properties:
Magnesium Stearate: Magnesium stearate is in the form of a white solid powder that is insoluble in water and soluble in certain organic solvents.
Magnesium Phosphatidate: Magnesium Phosphatidate is also in the form of a white solid powder that is soluble in water and can form some phosphorus-containing salts.
3. Application fields:
Magnesium stearate: Magnesium stearate is used as an auxiliary agent in cosmetics and pharmaceuticals. It has the functions of emulsification, thickening and lubrication. It is often used in the production of products such as creams, creams and ointments.
Magnesium Phosphatidate: Magnesium Phosphatidate is used as a phosphorus supplement and stabilizer to provide phosphorus during food processing and help maintain food stability and texture.
