Endpoint:
oxidising 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
Sample tested:
reference mixture (not specified)
Parameter:
maximum burning rate
Result:
1.23 mm/s
Sample tested:
other: 60:40
Parameter:
maximum burning rate
Result:
0.67 other: mm/s (migrated information)

Preliminary test

The preliminary screening test showed propagation over the cone within 4 minutes and 21 seconds. Therefore the full test was carried out.

Train test

The mixtures showed a slow propagation of the flame or the flame ceased before reaching the end of the distance of 200 mm.

Since the burning rate of the test item Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate was significantly shorter than the burning rate of the reference material, the test item has no oxidizing properties according to the definition in the Council Regulation (EC) No 440/2008EEC.

Interpretation of results:
GHS criteria not met
Executive summary:

In the Klimisch 1 study from Bütfering (2013) the oxidizing properties of Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate were determined according to EU test guideline A.17. Since the burning rate of the test item was significantly shorter than the burning rate of the reference material, the test item has no oxidizing properties according to the definition in the Council Regulation (EC) No 440/2008EEC.

 

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

Additional information

In the Klimisch 1 study from Bütfering (2013) the oxidizing properties of Sodium bis(C11-14-isoalkyl, C13-rich) sulfosuccinate

were determined according to EU test guideline A.17. Since the burning rate of the test item was significantly shorter than the burning rate of the reference material, the test item has no oxidizing properties according to the definition in the Council Regulation (EC) No 440/2008EEC.

 

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

Justification for classification or non-classification

Since the burning rate of the test item was significantly shorter than the burning rate of the reference material, the test item has no oxidizing properties according to the definition in the Council Regulation (EC) No 440/2008EEC.
