Applicant's summary and conclusion
- Conclusions:
- The particles size distribution has been determined by laser diffraction. 90% of the particles size stands below 236.3 µm; 50% below 80.2 µm and 10 % below 11.2 µm. MMAD is expected to be less than 100 µm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
