Description of key information

The particle size distribution of the substance was determined by laser diffraction. A summary of the findings is as follows:
D10 < 0,519 µm
D50 < 4,818 µm
D90 < 57,737 µm and
others 55,13% < 10 µm
The mass median diameter is 8,805 µm.

Additional information

A particle size analysis was conducted on the test material under GLP conditions using laser diffraction.

The Mass Median Diameter was determined to be 8.805 µm by laser diffraction. 55.13% of the particles were found to be < 10.00 µm. The D10, D50 and D90 were 0.519 µm, 4.818 µm and 57.737 µm, respectively. No nanosized particles were detected.
