Key Advantages
Enhanced Manufacturing Efficiency
Magnesium stearate ensures smooth operation of tablet presses by acting as an effective lubricant, significantly reducing friction and wear on machinery, which supports efficient tablet manufacturing.
Improved Tablet Quality
The anti-adhesive and flow-aiding properties of magnesium stearate contribute to consistent tablet hardness, reduced capping, and easier ejection, leading to higher quality end products.
Controlled Drug Release
While acting as a lubricant, magnesium stearate's concentration and blending time can subtly influence drug release kinetics, an important consideration in drug formulation science.
Key Applications
Tablet Lubrication
Magnesium stearate is widely used as a tablet lubricant to prevent sticking to punches and dies during compression, a key aspect of tablet manufacturing lubricants.
Capsule Manufacturing
In capsule production, it serves as an anti-adherent, ensuring powders flow freely and prevent adherence to manufacturing equipment.
Powder Flow Improvement
As a flow aid, magnesium stearate enhances the movement of powders through processing equipment, critical for pharmaceutical powder flow agents.
Excipient Functionality
Its role extends to influencing overall excipient properties and performance, making it a versatile component in advanced tablet production.
