Applicant's summary and conclusion
- Conclusions:
- The mass median value D50 for the particle size distribution is 23.1 µm.
- Executive summary:
The particle size distribution of the subsatnce was determined with a Malvern Mastersizer 2000 and the unit Scirocco 2000. The mass median diameter was found to be 23.1 µm.
