Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- GLP compliance:
- not specified
- Test procedure:
- other: burning time over 200 mm
- Burning time:
- 510 s
- Test procedure:
- other: burning time over 200 mm
- Burning time:
- 8.5 min
- Test procedure:
- ignition time on contact with air
- Remarks on result:
- no ignition on contact with air (not further specified)
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- C8 -18 AAPB proved to be not highly flammable (burn rate was 8.5 min/200 mm; criterion for classification as highly flammable: burn rate: < 45 s) in a study conducted according to EU Method A.10 (Flammability (Solids)).
- Executive summary:
The flammability of C8 -18 AAPB was investigated in a study conducted according to EU Method A.10 (Flammability (Solids)). The test item ignited by contact with a hot flame and burned calmly with a yellow flame. The burn rate was 8.5 min/200 mm. Therefore the test substance can be classified as not highly flammable as the criterion (burn rate: < 45 s) is not fulfilled.

Key value for chemical safety assessment
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
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.
