- Conclusions:
- The median particle size D50 of the test item deduced from the particle size distributions was 219.0 μm.
The particle size D10 of the test item deduced from the particle size distributions was 3.68 μm.
The particle size D90 of the test item deduced from the particle size distributions was 914.7 μm.
Reference
The particle size distribution showed a polymodal distribution. Maxima were observed at approximately 3 μm, 50 μm and 400 μm.
Description of key information
The median particle size D50 of the test item deduced from the particle size distributions was 219.0 μm.
Additional information
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.
