Reference
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.

Description of key information

not highly flammable (EU method A.10; RL2; no data on GLP); read-across C8-18 AAPB

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

No experimental data are available for the substance itself. However, reliable data are available for the closely related source substance C8 -18 AAPB.

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.

Due to close structural similarities no high flammability is expected for the target substance C8-10 Alkylamidopropyl betaine.
