- 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 wet dispersion.
The median mass diameter was determined as 71.71 µm, while the 10 %-quantile was 35.23 µm and the 90 %-quantile was 156.98 µm.
Reference
The following fractions were determined:
up to 2 µm: 0.2 %
2 -200 µm: 93.4 %
> 200 µm: 6.3 %
All %-values are the average of two measurements.
Description of key information
The median mass diameter was determined as 71.71 µm (reference 4.5-1).
