Reference
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 %

Please see attached report for tabulated results.

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.
