Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010-2-9
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Official print out from a Mastersizer 2000
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- A standard method using a Mastersizer analyser was used, serial number MAL 10245D4. The dispersant was water. Sensitivity was set to normal. The rpm was set at 2500 rpm. The concentration was 0.064%.
- GLP compliance:
- not specified
- Type of method:
- other: Not specified.
- Type of distribution:
- volumetric distribution
- Percentile:
- D10
- Mean:
- ca. 9.35 µm
- Remarks on result:
- other: No standard deviation provided.
- Percentile:
- D50
- Mean:
- 85.601 µm
- Remarks on result:
- other: No standard deviation provided.
- Percentile:
- D90
- Mean:
- 463.296 µm
- Remarks on result:
- other: No standard deviation provided.
- No.:
- #1
- Size:
- < 100 µm
- Distribution:
- 53.74 %
- Conclusions:
- The particle size distribution test indicates that 53.74 % of the substance has particles less than 100 microns and therefore can be considered to be potentially inhalable.
