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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 283-406-2 | CAS number: 84625-32-1 Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Eucalyptus globulus, Myrtaceae.

- density
- 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.

- Density:
- 0.927 g/cm³
- Temp.:
- 20 °C
- Executive summary:
The HSDB database provides, as secondary source, some physico-chemical properties. A density value of 0.9267 g/cm3 at 20°C is cited for cineole.
- Endpoint:
- relative density

- Executive summary:
The HSDB database provides, as secondary source, some physico-chemical properties. A relative density value of 0.8592 at 20°C is cited for alpha-pinene.
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Remarks:
- Data comes from the Certificate of Analysis in another test report. The substance is adequately caracterised, but the method is not specified. Therefore validation cannot be granted.
- Reason / purpose for cross-reference:
- reference to same study
- Principles of method if other than guideline:
- No data.
- Type:
- relative density
- Density:
- 0.909
- Temp.:
- 20 °C
- Remarks on result:
- other: D20/20
- Conclusions:
- Crude eucalyptus oil is less dense than water.
- Executive summary:
A Certificate of Analysis was provided with the sample used for testing other physico-chemical properties. The relative density D20/20 of 0.9086 is specified for the corresponding batch.
- Endpoint:
- relative density
- Type of information:
- other: ISO standard specifications
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Remarks:
- The value comes from an ISO standard, with reference to ISO method. Substance is adequately characterised with process and major component content. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 279
- Type of method:
- other: not specified
- Key result
- Type:
- relative density
- Density:
- >= 0.913 - <= 0.92 other: relative density is unitless
- Temp.:

- Remarks on result:
- other: D20/20
- Conclusions:
- Rectified eucalyptus oil is less dense than water.
- Executive summary:
An ISO standard provides requirements for the rectified oil of Eucalyptus Globulus oil: a density range of 0.913 to 0.920 is specified.

Description of key information
Both qualities are less dense than water.
Rectified oil: 0.913-0.920
Crude oil: ca 0.909
Key value for chemical safety assessment
Additional information
An ISO standard defines density requirements for the rectified grade. For the crude grade, literature data for the two components showing the highest variation in the composition (i.e. cineole, density ca 0.9267, decrease by ca -20%, and alpha-pinene, density ca 0.8592, increase by ca +18%) shows that significant decrease of density is anticipated, which is supported by internal data from a notifier.
It should be noted that due to UVCB nature of the substance, batch variations are expected.
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).
