Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 24 August 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline compliant study
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 66165
- GLP compliance:
- no
- Type of method:
- other: Optical characterization
- Type of distribution:
- other: diameter
- Percentile:
- D50
- Remarks on result:
- not determinable because of methodological limitations
- Remarks:
- cannot be determined due to the stickyness of the test material
- Executive summary:
In the non-GLP Klimisch 1 study from Bütfering (2013) the particle size distribution of Sulfosuccinic (isoFA C10)diE, Na should be determined according to DIN 66165 using the sieving method.
Due to the sticky and waxy product properties of the test item the particle size cannot be determined by sieving.Optical characterization indicated that the substance is sticky viscous mass.
This study is considered relevant for the risk assessment.
