Description of key information

The test substance, 1-Phenylethylbenzene, was determined to be non-flammable when in contact with water as there was no exothermicity and no gas evolution observed during the test. 

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The test substance, 1-Phenylethylbenzene, was determined to be non-flammable when in contact with water as there was no exothermicity and no gas evolution observed during the test.

1,1’-DPE has no structural alerts for pyrophoric properties. The comparison with the example substances listed in the “Guidance on information requirements and chemical safety assessment, Chapter R.7a, p.122, which are known to be flammable on contact with water, indicates that 1,1’-DPE is highly unlikely to display this property.

Justification for classification or non-classification

1,1 -DPE is not classified as flammable liquid, pyrophoric liquid or substance which in contact with water emits flammable gases.
