Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The particle size distribution of the substance was determined from a combination of manual sieve analysis and laser diffraction particle size analysis-'wet' small volume dispersion method (GLP-compliant study in accordance with OECD 110). Manual sieve analysis result: 98.89% by weight is > 250 µm, 0.18% by weight is < 63 µm. Laser diffraction particle size analysis result for the < 63 µm fraction: MMAD= 30.737 µm; 0.051% is < or = 10.00 µm; 10% is < 4.035 µm; 50% is < 28.295 µm and 90% is < 74.222 µm.
Additional information
MMAD of the entire sample was not determined as the results of PSD analysis of this substance should be compared with the read-across substance (see IUCLID section 13, Read-across report analogue approach) and therefore the test protocol of the analogue substance was followed as much as possible.
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.
