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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
The median particle size D50 (50 % of particle volume with lower particle diameter) deduced from these distributions are:
1st test series: D50 = 8.37 µm
2nd test series: D50 = 8.02 µm
The average of the median particle size D50 was 8.2 µm
The particle size D10 (10 % of particle volume with lower particle diameter) deduced from these distributions are:
1st test series: D10 = 1.58 µm
2nd test series: D10 = 1.50 µm
The average of the particle size D10 was 1.5 µm
The particle size D90 (90 % of particle volume with lower particle diameter) deduced from these distributions are:
1st test series:D90 = 79.27 µm
2ndtest series: D90 = 71.15 µm
The average of the particle size D90 was 75.2 µm
Description of key information
D10 = 1.5 µm
D50 = 8.2 µm
D90 = 75.2 µm

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
