Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
D50=179.23µm, laser diffraction, Füldner 2003
MMAD=248.5µm, air elutriation, Rattray 2004
Additional information
The median particle size determined by laser diffraction was 179.23µm (Füldner 2003). The mass median aerodynamic diameter determined by air elutriation (Rattray 2004) was extrapolated to be 248.5µm. The material tested was not considered to be respirable, and of low inhalability.
The available data is considered to be relevant, reliable, and adequate for risk assessment and classification purposes.
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.
