Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Qualifier:
no guideline followed
Principles of method if other than guideline:
Particle size distribution was determined using a sieve shaker. A set of 4 sieves were used (pore size 500, 300, 212 and 125 µm)
GLP compliance:
no
Type of method:
sieving
Type of distribution:
counted distribution
Percentile:
D50
Remarks on result:
other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.

Size:
< 125 µm
Distribution:
36.1 %
Conclusions:
The particle size distribution of the Calcium dodecylbenzenesulphonate was determined in a non-GLP study (2012) by using the dry sieve test.
Results:
<125µm: 36.1%
125-212µm: 39.8%
212-300µm: 14.9%
300-500µm: 7.7%
>500µm: 1.5%
Executive summary:

The particle size distribution of the Calcium dodecylbenzenesulphonate was determined in a non-GLP study (2012) by using the dry sieve test.
