Description of key information

Non autoflammable

Key value for chemical safety assessment

Additional information

Autoflammability has been tested on two similar substances that have in common the long chain (> C18) monoester derivative of sodium sulphosuccinate.

In the non-GLP study from Bütfering (2013) the self ignition temperature of Butanedioic acid, sulfo-, 4-[2-[(2-hydroxyethyl)amino]ethyl] ester, N-C18-unsatd. acyl derivs., disodium saltswas 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.

In the Nichetti study (2013) the same test has been performed with similar results. As a conclusion it can be deduced that also the registered substance has a self ignition temperature > 400°C

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