Description of key information

no Relative Self-Ignition Temperature

Key value for chemical safety assessment

Additional information

In the non-GLP Klimisch1 key study from Bütfering (2012) the self ignition temperature of the test item Butanedioic Acid, 2(or 3)-Sulfo-, 4-[2-[(1-Oxododecyl) amino] ethyl] ester, Disodium Salt was determined according to EU method A.16. The test item had no self ignition temperature above 400°C. Therefore the test item has no Relative Self-Ignition Temperature according to the definition in the Council Regulation (EC) No 440/2008, method A. 16.

This information is considered to be relevant and reliable for the further risk assessment.


A second study was performed with dust from the test item. Since this study was not performed according to the EU guideline A.16. the results of this study can not be used for the risk assessment. Therefore the results are not considered for the risk assessment.
