Applicant's summary and conclusion
- Conclusions:
- In total, 84.1% of the particles were determined to be >1000 µm.
- Executive summary:
The particle size distribution was assessed in a study performed according to OECD 110 and in compliance with GLP criteria. 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, 62.1% of the particles were >2000 µm and 84.1% was found in >1000 µm.
