- Conclusions:
- The median particle size D50 of the test item deduced from the particle size distributions was 13.3 µm.
The particle size D10 of the test item deduced from the particle size distributions was 5.3 µm.
The particle size D90 of the test item deduced from the particle size distributions was 25.8 µm. Small proportion (0.5%) has a particle size diameter <= 1 µm.
Reference
Multimodal distribution with a small shoulder at 1µm and a maximum at about 15µm.
Description of key information
Determination of particle size distribution by laser diffraction.Particle size distribution is multimodal with a small shoulder at 1µm, maximum at 15µm, median diameter L50=13.3µm particle size distribution is 1µm 0.5% and 10µm 32.7%.
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.
