Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- Testing for CAS 55184-72-0 is covered by tests with CAS 848588-96-5. Both substances are very similar since they differ mainly in the share of C13 (CAS 848588-96-5 C13> 80%; CAS 55184-72-0 > 95%). Hence, read across from CAS 848588-96-5 (source) to CAS 55184-72-0 (target) is considered as appropriate for both substances.
- Reason / purpose for cross-reference:
- read-across source
- GLP compliance:
- no
- Percentile:
- D50
- Mean:
- >= 30 - <= 40 mm
- Remarks on result:
- other: optical characterization(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
- Executive summary:
In the non-GLP Klimisch 1 study from Bütfering (2013) the particle size distribution of Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate was intended to be determined by sieving. Due to the pasty product properties of the test item Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate the particle size cannot be determined by sieving. Optical characterization indicated that the particles had a size of 0.2 to 4 cm with the main particle size in the range of 3 -4 cm.
This study is considered relevant for the risk assessment.
