Reference
Endpoint:
surface tension
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
Key result
Surface tension:
25.2 mN/m
Temp.:
20 °C
Conc.:
310 mg/L

Conclusions:
Surface tension: 25.2 mN/m
Executive summary:

In the non-GLP Klimisch 1 study from Kintrup (2012) the surface tension of Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate was determined according to test method EEC A.5 with the ring method at 20 °C and a concentration of 310 mg/L to be 25.2 mN/m.

The result is considered acceptable for the risk assessment.
