Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 01/06/2012 - 05/06/2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Non-GLP study according to protocol developed by fragrance industry. No deviations from protocol.
- Reason / purpose for cross-reference:
- reference to same study
- 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:
- Litsea cubeba oil is a Natural Complex Substance (NCS) with multiple constituents, therefore the 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
- Melting / freezing pt.:
- < -20 °C
- Conclusions:
- The melting point of Litsea cubeba oil is < -20ºC.
- Executive summary:
The melting point of Litsea cubeba 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
Litsea cubeba 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 Litsea cubeba oil is < -20ºC.
Reference
The substance was observed to be a clear mobile liquid at 20ºC, after 48 hours at 5ºC and after 48 hours at -20ºC.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
