Magnesium stearate is widely used in the pharmaceutical industry as an excipient in tableted drugs. The physical properties of the magnesium stearate influence the tableting characteristics of the formulation as well as the in vivo degradation and dissolution of the solid drug. The United States Pharmacopia, which has already established a standard for the particle size distribution of magnesium stearate, may adopt surface area standards for this material in the near future. To assist in this endeavor, Micromeritics obtained four samples of commercially available magnesium stearate and measured the BET surface area using the Micromeritics Gemini Surface Area Analyzer.
