Description of key information

C8 -18 AAPB: not highly flammable

Key value for chemical safety assessment

not classified

Additional information

In a study conducted according to EU Method A.10 (Flammability (Solids)), C8 -18 AAPB proved to be not highly flammable (burn rate: 8.5 min/200 mm; criterion for classification as highly flammable: burn rate: <45 s). 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.

Justification for classification or non-classification
