Applicant's summary and conclusion

Conclusions:
The mass median diameter of the particle size distribution of the substance is 12.6 µm.
Executive summary:

The particle size distribution of the substance was determined by laser diffraction using a ;alvern Mastersizer equipment. The mass median diameter D50 was found to be 12.6 µm.
