Reference
Endpoint:
flammable solids
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
Key result
Test procedure:
burning time (test type not further specified)
Remarks:
or specified in description of method (migrated information)
Burning time:
>= 240 s
Remarks on result:
other: No propagation of the flame => Burning time in seconds for a distance of 200 mm.
Key result
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
Based on observation of the dried material.

The preliminary screening test shows no propagation of the flame and the flame ceases a few seconds after removing the gas burner. Therefore the combustion is beyond the specified time frame for flammability of 4 minutes for 200 mm.

According to the definition in the Council Regulation (EC) No 440/2008EEC the test item Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate is not considered as flammable.

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
According to the definition in the Council Regulation (EC) No 440/2008EEC the test item is not considered as flammable.
Executive summary:

In the non-GLP Klimisch 1 study from Bütfering (2013), the flamability of Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate was determined according to EU method A.10. The preliminary screening test shows no propagation of the flame and the flame ceases a few seconds after removing the gas burner. Therefore the combustion is beyond the specified time frame for flammability of 4 minutes for 200 mm.
