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).
