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 specifically for testing.
Reference:
Composition 0
Qualifier:
equivalent or similar to
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
Test material information:
Composition 1
Specific details on test material used for the study:
The substance is produced as a solution and it was dried
Mass median aerodynamic diameter:
> 250 µm
Key result
Percentile:
D25
Mean:
> 250 µm
Remarks on result:
other: standard deviation not determined
No.:
#1
Size:
< 250 µm
Distribution:
ca. 22 %
No.:
#2
Size:
< 63 µm
Distribution:
< 2 %

The particle size was found to be predominatly > 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 < 2 %

Conclusions:
The particle size was found to be > 250 micron.

Description of key information

The particle size was found to be predominantly > 250 micron with ca 78% not passing through this seive

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 < 1.6 %
