Reference
Endpoint:
relative self-ignition temperature (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
GLP compliance:
no
Key result
Relative self-ignition temperature:
> 400 °C
Remarks on result:
other: The test was performed in an oven at normal atmospheric pressure

The test item doesn’t reach 400 °C during the self ignition. Therefore the test item Sodium bis(C11-14-isoalkyl,C13-rich) sulfosuccinate has no Relative Self-Ignition Temperature according to the definition in the Council Regulation (EC) No 440/2008, method A. 16.

Conclusions:
relative self ignition temperature > 400 °C
Executive summary:

In the Klimisch 1 study from Bütfering (2013) the relative self ignition temperature of Sodium bis(C11-14-isoalkyl,C13-rich) sulfosuccinate was determined according to EU test guideline A.16. The test item doesn’t reach 400 °C during the self ignition. Therefore the test item Sodium bis(C11-14-isoalkyl,C13-rich) sulfosuccinate has no Relative Self-Ignition Temperature according to the definition in the Council Regulation (EC) No 440/2008, method A. 16.

 

The results of this study are considered reliable and relevant for the risk assessment.
