Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
ca. 16% <100µm
ca. 2.3% <10µm
ca.0.1 % <4µm
Additional information
The determination of the particle size distribution was carried out by laser diffraction according to ISO 13320-1, with evaluation according to
Fraunhofer.
The inhalable fraction (particles < 100µm) is defined as the mass fraction of particles which can be inhaled by nose or mouth, the thoracic fraction (50% of particles <10µm) is defined as the mass fraction of particles that passes the larynx and the respirable fraction (50% of particles < 4µm) is defined as the mass fraction of particles that reaches the alveoli.
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.
