Magnesium stearate is the most widely used lubricant in pharmaceutical tablet and capsule manufacturing.
It forms a thin hydrophobic layer on particle surfaces, reducing friction, preventing sticking to punches and dies, and enabling smooth ejection from the press.
At low concentrations, it significantly improves manufacturing efficiency and equipment life without affecting tablet hardness when properly controlled.
It is also used in nutraceuticals, cosmetics, and food products as an anti-caking and release agent.
Pharmacopeial grades are tightly specified for fatty acid composition, purity, and microbial quality to meet regulatory expectations.
