Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key study: Particle size data was acquired, using a procedure designed to be compatible with the European Commission Technical Guidance Document EUR 20268: Determination of Particle Size Distribution, Fibre Length and Diameter Distribution of chemical substances (2002). GLP study.
Proportion of test item having an inhalable particle size <100 μm: 94.3% (Sieve method)
Proportion of test item having a thoracic particle size <10.0 μm: 0.498% (Cascade Impactor method)
Proportion of test item having a respirable particle size <5.5 μm: 5.97 x 10E-02% (Cascade Impactor method)
Too few particles were of a size less than 10.0 μm to allow accurate assessment of the mass median aerodynamic diameter.

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.
