Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 29 August 2012 to 02 October 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. Substance ID is adequately specified with purity and isomers composition. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP Compliance Programme (inspected on 10 July 2012 / signed on 30 Nov. 2012)
- Type of method:
- pycnometer method
- Specific details on test material used for the study:
- - Storage condition of test material: room temperature, in the dark.
- Dynamic viscosity of test material:
- A kinematic viscosity of 8.37 mm2/s at 20°C was measured (please refer to IU section 4.22), corresponding to a dynamic viscosity of 7.8 mPa.s with the present density.
- Key result
- Type:
- relative density
- Density:
- 0.936 other: relative density is dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The substance is less dense than water.
- Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method.
Two runs were performed, and the mean density at 20.0°C was calculated. This result was then converted to relative density towards water at 4°C.
The relative density of the test substance at 20 ºC was 0.936.

Description of key information
The substance is less dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.936
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study, and the result is retained as key data for purpose of CSA.
