Frequently asked questions for Magnesium Stearate and its applications

  • The particle size distribution measured by laser diffraction is available for each product in their product profiles. The table below gathers all those values:

      Roquette Magnesium Stearate LS  Roquette Magnesium Stearate  Roquette Magnesium Stearate HS
     Specific surface area  Below 5 m2 / g Between 5 and 10 m2 / g  Above 10 m2 / g
     D10 (µm)  6.8  1.4  4.3
     D50 (µm)  14.8  7.8  10.7
     D90 (µm)  33.1  27.5  22.8

    Note that the values obtained from the measurement of particle size distribution are known to vary between methods and equipment. Since each method has its own working principles and inherent limitations, the results obtained may be highly dependent on and/or specific to the method employed. Comparisons between samples should be made when the same method/procedure is employed. 

  • Scanning electron microscopy pictures (SEM) are gathered below for all Roquette Magnesium Stearate grades:

  • The range of Roquette Magnesium Stearate is composed of three grades differentiated by their specific surface areas:

    -  Roquette Magnesium Stearate LS has a low specific surface area, lower than 5 m²/g.

    -  Roquette Magnesium Stearate has a medium specific surface area, between 5 m²/g and 10 m²/g.

    -  Roquette Magnesium Stearate HS has a high specific surface area, higher than 10 m²/g.
