Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Endpoint:
- melting point/freezing point
- Type of information:
- not specified
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- Data comes from an online compilation using secondary data sources. There is no experimental study reference, however data is cited in the database as peer reviewed. Therefore it is considered as reliable, but with restrictions due to lack of details.
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to other study
- Principles of method if other than guideline:
- No data.
- Melting / freezing pt.:
- 1.5 °C
- Executive summary:
The HSDB database provides, as secondary source, some physico-chemical properties. A melting/freezing point of 1.5°C is cited for cineole.

- Executive summary:
The HSDB database provides, as secondary source, some physico-chemical properties. A melting/freezing point of -62.5°C is cited for alpha-pinene.
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Remarks:
- The study has been conducted according to guidance on NCS. The substance is adequately caracterised. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- other: EFFA/EFEO guideline "The Registration for REACH of Natural Complex Substances used as Fragrance Ingredients"
- GLP compliance:
- no
- Type of method:
- other: Visual observation after equilibrium at +5°C and -20°C.
- Key result
- Melting / freezing pt.:
- < -20 °C
- Conclusions:
- Freezing point < -20°C.
No further testing required. - Executive summary:
The physical state of the test substance was observed after 2-day equilibration at +5°C and -20°C, according to EFFA/EFEO Recommendations for NCS. The sample remained liquid.

Description of key information
Crude quality: Freezing point < -20°C (exp.).
Rectified quality: Freezing point anticipated < +5°C (extrap.).
Key value for chemical safety assessment
Additional information
An experimental study is available for the crude quality, based on observation at given temperatures (+5°C and -20°C), as recommended for NCS: the substance remained liquid at the lowest temperature tested.
For the rectified quality, literature data for the two components showing the highest variation in the composition (i.e. cineole, m.p.=1.5°C, increase by ca +20%, and alpha-pinene, m.p.=-62.5°C, decrease by ca -18%) show that increase of freezing point is anticipated. However, based on these values, it is expected to remain at least below the testing threshold of +5°C.
Results expressed as limit values cannot be retained as key data for purpose of CSA.
It should be noted that due to UVCB nature of the substance, batch variations are expected.
