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:
- Lemongrass oil (Cymbopogon flexuosus) 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 observation

Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- < -20 °C
Any other information on results incl. tables
The substance was observed to be a clear mobile liquid at 20ºC, after 48 hours at 5ºC and after 48 hours at -20ºC.
Applicant's summary and conclusion
- Conclusions:
- The melting point of Lemongrass oil is < -20ºC.
- Executive summary:
The melting point of Lemongrass 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
Lemongrass oil is a mobile liquid at 20ºC and a mobile liquid after 2 days at -20ºC. Therefore, it was concluded that the melting point of Lemongrass oil is < -20ºC.
