- Percentile:
- D50
- Mean:
- 23.948 µm
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
- Percentile:
- D50
- Mean:

- 3.1
Any other information on results incl. tables
Given standard deviation is based on the general experience with the method. The estimated value is a typical standard deviation:
D50: 13 % of D50 (minimum value 0.1 µm)
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
