Endpoint:
relative density
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:
read-across source
GLP compliance:
no
Type:
relative density
Density:
1.044
Temp.:
20 °C
Remarks on result:
other: The relative density is dimensionless

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.

Executive summary:

The relative density of Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate was determined by Frischmann (2012) in a Klimisch 1 non-GLP study according to EC A.3 and OECD 109 by using the pycnometer method. The test item has a relative density D420 of 1.044 which corresponds to 1.044 g/cm ³.

The results of this test are considered to be relevant and reliable for the assessment.
