Results and discussion
Particle size
- Percentile:
- D50
- Mean:
- 24 µm
Applicant's summary and conclusion
- Conclusions:
- The median particle size is D50 = 24 µm
- Executive summary:
The particle size distribution was measured with laser scattering with the Malvern Mastersizer 2000. The measurement was conducted similar to ISO 13320. The test material was introduced into the laser beam with a dry dispersion cell.
The result of the median particle size is D50 = 24 µm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
