Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The particle size distribution is determined experimentally. 9.3 % of the substance show a size < 100 µm. The tenth percentile, D10 is determined to 102 µm. Furthermore, D50 resp. D90 are determined to 702 µm resp. 1508 µm.

Additional information

The particle size distribution is determined in a guideline study following the quality requirements of GLP. No or only minor deviations could be detected during determination. The result could therefore be considered as valid and is chosen as key value for the chemical safety assessment.
