Magnesium Stearate is a fine, white, hydrophobic powder with a bulk density of 0.2–0.4 g/cm³ and a melting point of approximately 120–130°C. It is insoluble in water but soluble in hot organic solvents. Widely used as a lubricant and anti-caking agent in pharmaceuticals, capsules, and food supplements, it improves powder flow during manufacturing and ensures consistent product quality.

Application
1. PVC Heat Stabilizer
In addition to its role as a lubricant, magnesium stearate serves as a critical heat stabilizer in the polyvinyl chloride (PVC) industry. During PVC processing, it effectively inhibits volatilization and thermal degradation of various flammable materials-from fuses to imaging equipment-thereby ensuring thermal stability.
2. Dispersant and Lubricant for Polymer Materials
In the field of polymer functional materials, magnesium stearate provides a dual function: it promotes uniform dispersion of fillers and additives, and significantly reduces friction between machinery and the material. This improves processing stability and enhances the overall performance and quality of polymer products
3. Lubricant and Anti sticking Agent for Tablets
Magnesium stearate is widely used as a lubricant and anti sticking agent. During compression, it prevents powder from adhering to punches and dies, improves the surface appearance of tablets, and greatly increases production efficiency.
4. Functional Additive for Cosmetics
In cosmetic manufacturing, magnesium stearate is commonly employed as a thickener, lubricant, and anti caking agent to optimize product texture, application feel, and stability.
