- Conclusions:
- The median particle sizes of the test item deduced from the particle size distributions (volumetric) were: L50 = 27.5 μm, L10 = 9.4 μm and L90 = 67.8 μm (ISO 13320, Laser diffraction method)
Reference
The percentage of particles < 2 µm is < 2.2 % and >=200 µm is < 0.1 %.
The substance consists of rod-shaped crystals.
Description of key information
Median particle sizes: L50 = 27.5 μm, L10 = 9.4 μm and L90 = 67.8 μm (ISO 13320, Laser diffraction method)
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.
