Surface Area of Magnesium Stearate Using the Volumetric Method
Click below to download this Application Note
Magnesium stearate, a waxy, lamellar (platy) solid, is a widely used excipient in pharmaceutical technology. Primarily, magnesium stearate is added to a formulation in order to modify compaction behavior and reduce ejection forces from tablet dies and is available in a range of grades having similar or different surface area. The NOVAtouch is ideal for specific surface area measurements according to USP <846> Method II (volumetric method) and the well-known BET  calculation described therein.
