- Executive summary:
The particle size distribution was determined in an experimental study under GLP conditions according to OECD Test Guideline 110 using the laser diffraction method with dry dispersion.
The median particle diameter was determined as 80.31 µm, while the 10%-quantile was 10.23 µm and the 90%-quantile was 387.54 µm.
Reference
The particle size distribution was determined in an experimental study under GLP conditions according to OECD Test Guideline 110 using the laser diffraction method.
The median mass diameter was determined as 80.31 µm, while the 10% quantile was 10.23 µm and the 90%-quantile was 387.54 µm.
This corresponded with the following fractions:
up to 2 µm: 0.8%
2 -200 µm: 76.1%
> 200 µm: 23.1%
All %-values are the average of two measurements.
Description of key information
The median particle diameter was determined as 80.31 µm, while the 10 %-quantile was 10.23 µm and the 90 %-quantile was 387.54 µm (reference 4.5-1).
