Applicant's summary and conclusion

Conclusions:
Cinnamon leaf oil is a clear mobile liquid at 20 degrees Celsius and a clear mobile liquid after 48h at -20 degrees Celsius.
Executive summary:

Cinnamon Leaf Oil is a mixture of substances and transition from liquid to solid will not be sharp. The „Guidance on information requirements and chemical safetyassessment Chapter R.7a: Endpoint specific guidance" from ECHA mentions in chapter R.7.1.2.3, that melting points are not normally carried out for mixtures. Therefore it is recommended in the EFFA/EFEO guideline "The Registration for REACH of Natural Complex Substances used as Fragrance Ingredients" to describe the state of the essential oil after two days at +5°C -if still a liquid the test has to be repeated at -20°C- rather than determining a transition temperature.

The melting point of cinnamon leaf oil was investigated by visual observation accordint to the NCS protocol. Cinnamon leaf oil was found to be a clear mobile liquid at 20 degrees Celsius and a clear mobile liquid after 48h at -20 degrees Celsius.
