Application of Magnesium Stearate

Magnesium stearate has a variety of roles and is widely used in the pharmaceutical and food industries. The following are the main roles of magnesium stearate:

Lubricant: magnesium stearate is a new type of pharmaceutical excipient, which can be used as a film-forming coating material for solid preparations, a thickening agent for colloidal liquid preparations, a suspending agent and so on. It has good lubricating properties, which can reduce the adhesion and sticking of tablets, capsules or powders in the process of preparation and packaging and ensure the fluidity and stability of the products. It is used in cosmetics for powder products to enhance adhesion and lubrication.

Anti-adhesion agent: Magnesium Stearate reduces the adhesion between pharmaceutical or food ingredients and prevents solid particles from agglomerating and sticking to the surface of the container.

Stabilizer: Magnesium Stearate can improve the stability of drugs or foods, reduce oxidation and decomposition reactions, and extend the shelf life of products.

Dispersing agent: magnesium stearate can evenly disperse solid ingredients in liquid, improving the homogeneity and stability of the mixture.

Release agent: Magnesium Stearate can be used as a release agent in pharmaceutical processes to facilitate the separation of drugs from molds or containers and maintain the integrity of the drug.

Besides, magnesium stearate is used as a heat stabilizer for polyvinyl chloride, as well as raw material for cosmetic flour, emollient ointment and pharmaceutical tablets (excipient, lubricant); it is used for lubricating and bright and transparent school wood powder; it is used as an evident leveling agent for paint industry, and so on.


Functions and Indications of Magnesium Stearate

Magnesium stearate has a wide range of applications in the field of medicine and food, mainly used in the following functions:

Pharmaceutical preparations: In pharmaceutical preparations, magnesium stearate is often used as an auxiliary agent to improve drug fluidity, stability and solubility. It is commonly used in tablets, capsules, and powder preparations and can reduce the irritation of drugs to the gastrointestinal tract.

Food Additive: Magnesium Stearate is widely used as a food additive with lubricating, anti-adhesion and dispersing properties. It is commonly used in chocolate, candy, chewing gum, oral liquid, fruit juice and other foods to improve the taste and stability of products.

Cosmetics: Magnesium stearate can be used as a dispersant, stabilizer, and lubricant. It can improve the texture, prolong the shelf life of cosmetics, and increase the smoothness and silky feeling of the products.

Plastics and rubber industry: Magnesium stearate can be used as an additive in the plastics and rubber industry to improve product processing performance and lubricity. It is commonly used to prepare plastic products, rubber products and coatings.

Medical Devices: Magnesium Stearate can be used as a release agent for medical devices to help the devices to be detached from the mold. It is commonly used to prepare medical tape, catheters, syringes and other medical devices.
