Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 295-995-3 | CAS number: 92201-64-4 Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Eucalyptus radiata australiana, Myrtaceae.
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:
- March 8-9th, 2022
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- An experimental non-GLP study was conducted according to the protocol developed from by EFFA/EFEO. The substance is adequately identified. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- other: EFFA/EFEO guideline "The Registration for REACH of Natural Complex Substances used as Fragrance Ingredients"
- Deviations:
- no
- Principles of method if other than guideline:
- Visual observation of physical state at different temperatures.
- GLP compliance:
- no
- Type of method:
- other: Visual Observation
- Melting / freezing pt.:
- < -20 °C
- Remarks on result:
- other: Experimental pressure not specified but supposed to be the standard atmospheric pressure
- Conclusions:
- The freezing point of the test item was stated to be lower than -20°C at 101.3 kPa.
No further testing required. - Executive summary:
The melting point of the test substance 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 the test substance is a mobile liquid at 20°C and a mobile liquid after 2 days at -20°C.
Therefore, it was concluded that the freezing point of the test item islower than -20°C at 101.3 kPa
Reference
Table 1: Melting / Freezing Point
Temperature | +20°C | +5°C for 48h | -20°C for 48h |
State of sample 1 | clear mobile liquid | clear mobile liquid | clear mobile liquid |
State of sample 2 | clear mobile liquid | clear mobile liquid | clear mobile liquid |
Although the viscosity increased at the lowest temperature, the consistency remained unchanged. No freezing point could be obtained.
Description of key information
The freezing point of the test item was stated to be lower than -20°C at 101.3 kPa.
Key value for chemical safety assessment
Additional information
A fully reliable experimental study is available, based on observation at given temperatures (+5°C and -20°C), as recommended for NCS: the substance remained liquid at the lowest temperature tested.
Results expressed as limit values cannot be retained as key data for purpose of CSA.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
