Results and discussion

Flammable solids
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Executive summary:

The flammability was performed according to the EU-Method A.10 and UN N.1.

In the preliminary screening test following the EU method, the test item was heated with the flame of a teclu burner. The test item melted to a slightly yellowish liquid. No ignition occurred within two minutes.

Therefore, the test itemHydrogenated olive oil cetyl estershould be considered as

not highly flammable (for EU regulations) and non-flammable solid (for UN regulations)
