Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: "The Registration for REACH of Natural Complex Substances used as Fragrance Ingredients" by EFFA/EFEO
Deviations:
no
Principles of method if other than guideline:
CINNAMON BARK OIL is a mixture of substances and transition from liquid to solid will not be sharp. The „Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance” from ECHA mentions in chapter R7.1.2.3, 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 an essential oil after two days at +5°C and -20 °C rather than determining a transition temperature.
GLP compliance:
no

Results and discussion

Melting / freezing point
Melting / freezing pt.:
< -24 °C

Any other information on results incl. tables

Cinnamon bark oil is a yellow mobile liquid at 20ºC and a yellow slightly viscous liquid after 2 days at -24ºC.

Applicant's summary and conclusion

Conclusions:
The melting point of cinnamon bark oil is < -24ºC.
Executive summary:

The melting point of cinnamon bark oil was investigated according to the methodology proposed by the EFFA/EFEO guideline „The Registration for REACH of Natural Complex Substances used as Fragrance Ingredients”. By visual observation it was found that

Cinnamon bark oil is a yellow mobile liquid at 20ºC and a yellow slightly viscous liquid after 2 days at -24ºC. Therefore, it was concluded that the melting point of cinnamon bark oil is < -24ºC.
