Application：

Pharmaceutical Industry: Magnesium Stearate is widely used as a lubricant and flow agent in tablet and capsule manufacturing, ensuring smooth processing and preventing ingredients from sticking to equipment. It also improves the uniformity of the final product by enhancing the flow of powders during production.

Cosmetics and Personal Care: In cosmetics, it is used in face powders, eye shadows, blushes, and foundation products to improve texture, enhance spreadability, and provide a smooth, silky feel on the skin. Its anti-caking properties help maintain the quality and consistency of powdered products.

Food Industry: Used as an anti-caking agent and emulsifier in food production, Magnesium Stearate helps prevent clumping and ensures smooth, even mixing of ingredients in products such as spices, powdered drink mixes, and dietary supplements.

Plastic and Rubber Industry: It acts as a release agent and internal lubricant in the production of plastics and rubbers, reducing friction and preventing products from sticking to molds, thereby improving the quality and consistency of the final product.

As a fatty acid salt type anion surfactant, magnesium stearate is widely used in the daily chemical industry and the pharmaceuticals industry.

(1) Since it has great stickiness on skins and excellent lubricity, it is used in powder type cosmetic products to increase their stickiness and lubricity.

(2) It can be used as heat stabilizer for polyvinyl chloride; its stablizing effect is similar to that of calcium stearate, and can be used in food packaging materials together with zinc soaps or calcium soaps.

(3)It can be used as plastic products’ release agent, face powder, raw material for skin oil/cream, powder mold agent for medical tablets, and translucent flatting agent for paintings.

Usage Guidelines:

Pharmaceutical Formulations: Incorporate Magnesium Stearate at levels of 0.25% to 5% in tablet and capsule manufacturing. It should be mixed with other ingredients to ensure even distribution and prevent sticking to machinery, optimizing production efficiency and product quality.

Cosmetic Applications: Use Magnesium Stearate in cosmetic formulations at concentrations of 1% to 10% to enhance texture, improve spreadability, and prevent caking. It can be blended with other powders and pigments for uniform dispersion in makeup products.

Food Production: In food applications, use Magnesium Stearate at levels up to 2% as an anti-caking agent. It should be mixed with other dry ingredients to prevent clumping and ensure a smooth, free-flowing product, particularly in powdered goods and spice blends.

Plastic and Rubber Manufacturing: Add Magnesium Stearate at concentrations of 0.5% to 3% as a release agent and lubricant. It should be uniformly mixed into the polymer or rubber compound to enhance processing, reduce friction, and improve the final product’s quality.

Handling and Storage: Handle Magnesium Stearate with appropriate personal protective equipment to avoid inhalation of dust and skin contact. Store in a cool, dry place away from moisture and direct heat to maintain its stability and effectiveness.

Regulatory Compliance: Ensure that the use of Magnesium Stearate complies with local and international regulations, especially in food and pharmaceutical applications. It is generally recognized as safe (GRAS) by the FDA and other regulatory bodies, but specific usage guidelines should be followed based on the application.
