Applicant's summary and conclusion
- Conclusions:
- Using a laser diffraction apparatus, particle size of test item in the range between 0.3 μm and 300 μm the mass median diameter (MMD) was determined to be 3.0 μm. The particle size distribution was found to range from approximately 0.5 μm to 10 μm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
