- Geometric standard deviation:
- >= 2.36 - <= 2.37
- Percentile:
- D10
- Mean:
- >= 7.874 - <= 8.115 µm
- St. dev.:
- 0.087
- Key result
- Percentile:
- D50
- Mean:
- >= 24.22 - <= 24.962 µm
- St. dev.:
- 0.273
- Percentile:
- D90

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
