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
- Type of method:
- other: Visual inspection

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.
