Description of key information

The particle size distribution of a sample of the substance was determined (volumetric distribution): 10%  is < 4.2 µm; 27.5% is < 10 µm; 50% is < 14.1 µm and 90% is < 25.5 µm. The MMAD (mean of 5 measurements) is 27.2 µm.

Additional information

Determined in a GLP-compliant study using the laser diffraction analysis-'wet' small volume dispersion method, with kerosene as dispersant..
