Any other information on results incl. tables
All measured values show good reproducibility, giving deviations of less than 2%.
The particle size distribution shows no single peaks, but a continuous distribution roughly between 25 and 80 µm, leaving fractions of less than 20% above 80 µm and less than 10% below 25 µm.
Applicant's summary and conclusion
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.
