Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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 for cross-reference:
read-across source
GLP compliance:
no
Key result
Surface tension:
25.2 mN/m
Temp.:
20 °C
Conc.:
310 mg/L

Hence, read across from CAS 848588-96-5 (source) to CAS 55184-72-0 (target) is considered as appropriate for both substances.

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.
