Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Total Dustiness (airborne fraction): 142.49 mg/g (experimental results, DMT Report).
Mass median aerodynamic diameter of airborne fraction: MMAD = 386.76 µm(cascade impactor data). Geometric standard deviation of MMAD: GSD =15.69 (modified Heubach rotating drum method).
Fractional deposition in human respiratory tract (MPPD model, based on calculated MMAD):
Head (ET): 7.7%
Tracheobronchial (TB): 0.3%
Pulmonary (PU): 0.7%
The median particle size D 50 of the test items deduced from the particle size distribution is 1.4µm.
The particle size D 10 of the test items deduced from the particle size distribution is 0.5µm.
The particle size D 90 of the test items deduced from the particle size distribution is 7.3µm.
Additional information
MMAD(airborne fraction) = 386.76 µm, GSD =15.69
D 10 = 0.5µm.
D 50 = 1.4µm.
D 90 = 7.3µm.
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.
