- Conclusions:
- The relative self-ignition temperature of C12 AAPB was investigated in a study conducted according to EU Method A.16 (Relative Self-Ignition Temperature for Solids). Up to the decomposition temperature (260°C) no self-ignition temperature was observed.
- Executive summary:
The relative self-ignition temperature of C12 AAPB was investigated in a study conducted according to EU Method A.16 (Relative Self-Ignition Temperature for Solids). C12 AAPB is a solid substance. The particles are spherical and porous. C12 AAPB decompose in two steps between 60 and 260°C. Up to the decomposition temperature (260°C) no self-ignition temperature was observed..

Description of key information
relative self-ignition temperature of C8 -18 AAPB: no self-ignition temperature observed up to the decompostion temperature (208°C)
relative self-ignition temperature of C12 AAPB: no self-ignition temperature observed up to the decomposition temperature (260°C)
Key value for chemical safety assessment
Additional information
In studies conducted according to EU Method A.16 (Relative Self-Ignition Temperature for Solids), the relative self-ignition temperature of C8 -18 AAPB and C12 AAPB was investigated. Up to the decomposition temperatures (>=208°C) no self-ignition temperature was observed. All AAPBs are similar in structure, contain all the same zwitterionic structure. They differ, however, by their carbon chain length distribution and the degree of unsaturation (<=20%) in the fatty acid moiety. The content of minor constituents in all products are comparable and differ to an irrelevant amount. Based on the available data, it can be assumed that chain length distribution and degree of unsaturation of the fatty acid chain have a minor impact on this endpoint.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
