Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
