Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
6 independent measurements were performed. The average size (D50) of the substance particles was determined to be 53.2 µm.

The following particle size distribution was found:
< 2 µm: 2% w/w
>= 2 and <= 200 µm: 90% w/w
> 200 µm: 8% w/w
