Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
C8-18 AAPB: not identifyable due to decomposition of the test substance in the range between 208 and 280°C
C12 AAPB: not identifyable due to decomposition of the test substance in the range between 60 and 260°C
Key value for chemical safety assessment
Additional information
In studies conducted according to OECD Guideline 103, the boiling points of C8 -18 AAPB and C12 AAPB were investigated using differential scanning calorimetry (DSC). Boiling points were not identifyable due to decomposition of the test material in the range between 208 and 280°C (C8 -18 AAPB) and between 60 and 260°C (C12 AAPB). Based on these results it can be assumed that a weak chemical bond is present in the molecule which is unstable towards elevated temperatures. 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 no or at the most 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
