Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
Testing performed by manufacturer using recognised methods.
The substance is typically supplied in water and was dried secifically for testing.
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions - Method A: Particle Size Distribution (effective hydrodynamic radius)
Principles of method if other than guideline:
Seiving methods
GLP compliance:
no
Type of method:
sieving
Type of particle tested:
primary particle
Type of distribution:
mass based distribution
Specific details on test material used for the study:
The substance is produced as a solution and it was dried at 200 oC to obtain the anhydrous form.
Batch number of test material : Z-09-2715
Mass median aerodynamic diameter:
ca. 100 µm
Key result
Percentile:
D25
Mean:
< 63 µm
Remarks on result:
other: stnadard deviation not determined
No.:
#1
Size:
< 250 µm
Distribution:
ca. 100 %
No.:
#2
Size:
> 63 µm
Distribution:
> 72 %
No.:
#3
Size:
< 63 µm
Distribution:
< 28 %

The particle size was found to be < 250 micron. An assessment of the dust content was made on the basis of particles passing through a 63 micron sieve. The amount by weight of particles of less than 63 microns was 28 %

Conclusions:
The particle size was found to be < 250 micron. An assessment of the dust content was made on the basis of particles passing through a 63 micron sieve. The amount by weight of particles of less than 63 microns was 28 %
