Applicant's summary and conclusion
- Conclusions:
- The particle size distribution was determined using the laser diffraction method with dry dispersion, in 6 measurements.
The volume mean diameter of sample is 71.85 um and its 90%, 50% and 10% cumulative size distributions are 213.76 um, 26.56 um and 3.07 um respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
