Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusions:
The particle size distribution of the dispersed test item (not micronized) has been determined:
D(90): 60.52 µm - 74.38 µm
D(50): 22.58 µm - 29.21 µm
D(10): 4.26 µm - 4.93 µm
Executive summary:

The particle size distribution of the dispersed test item (not micronized) has been determined in four experiments by laser diffraction. For each experiment three measurements were conducted and the average volumetric particle size distribution was reported, respectively.
