Applicant's summary and conclusion

Conclusions:
In total, 58.3% of the particles were determined to be >1000 µm and 3.4% was found to be <106 µm.
Executive summary:

Particle size distribution was determined in a GLP-compliant study, performed according to OECD guideline 110. The particle size distribution was determined to be with the sieving method.

The particle size distribution was assessed in a study performed according to OECD 110 and in compliance with GLP criteria via sieving. The weight of particle sizes was determined for the particle sizes 45-90, 90-106, 106-150, 150-595, 595-1000, 1000-2000 and >2000 µm. In total, 29.2% of the particles were >2000 µm, 58.3% was found in >1000 µm and 95.3% of the particles was >150 µm.
