Results and discussion
Particle size
- Percentile:
- D50
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
Particle size distribution at different passages
- No.:
- #1
- Size:
- < 100 µm
- Distribution:
- < 0.662 %
Applicant's summary and conclusion
- Conclusions:
- The proportion of test material having an inhalable particle size of less than 100 µm was 0.662%. The test material has beend determined to be essentially non-inhalable.
- Executive summary:
The test material has been determined to be essentially non-inhalable using OECD Test Guideline 110 (inhalable particle size of less than 100 µm was < 0.662%).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
