Applicant's summary and conclusion
- Conclusions:
- The median particle size L50 of the test items deduced from the particle size distributions is 12.5 um
The particle size L10 of the test items deduced from the particle size distributions is 1.6 um
The particle size L90 of the test items deduced from the particle size distributions is 246.4 um - Executive summary:
The particle size distribution (volume distribution) of the test item was measured by laser diffraction with dry dispersing.
The median particle size L50 of the test items deduced from the particle size distributions is 12.5 um.
The particle size L10 of the test items deduced from the particle size distributions is 1.6 um.
The particle size L90 of the test items deduced from the particle size distributions is 146.2 um
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
