Description of key information

In house company data showed a particle size distribution with D10, D50 and D90 values of 25.65 µm, 86.5 µm and 211 µm, respectively, for one batch (Coustet, 2011) and D10, D50 and D90 values of 11.28 µm, 23.11 µm and 71.64 µm, respectively, for another batch (Coustet, 2012). 

Additional information

Two in-house company studies were included in this dossier. The particle size is expressed as "circle equivalent diameter" (the diameter of a circle with the same area as the 2D image of the particle). Overall, obtained D10, D50 and D90 values varied between 11.28 (lowest D10) and 211 µm (highest D90).
