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.

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.

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.

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.

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.
