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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Particle Size Distribution:
% test material particle size (microns)
3.51 <= 2.00
21.40 <= 10.1
99.51 <= 203.3
Mass Median Diameter: Calculated mass median aerodynamic diameter: 40 microns
Calculated percentage <10 microns aerodynamic diameter: 9.5%
Additional information
Although the calculated proportion of particles with an aerodynamic diameter less than 10 µm is less than 10% it is considered that, given the assumptions made in the calculation and the possible bimodal nature of ther size distribution, (there appears to be a sub-population of very small particles), we advise that there is some potential for inhalation of this material.
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.
