Applicant's summary and conclusion
- Conclusions:
- The particle size distribution of the test substance has been determined by laser diffraction (non-GLP, 2015) and the following results have been obtained for the sample tested:
D10 = 51.175 μm
D50 = 297.628 μm= mass median diameter (MMD)
D90 = 425.207 μm
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
