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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- experimental dates: August 06, 2008
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognized method, and under GLP; however, calibration was not suitable. Test substance is adequately specified. Therefore validation applies with minor restrictions on accuracy.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- July 27, 1995
- Deviations:
- yes
- Remarks:
- calibration
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- EEC Directive 92/69, L383, December 1992
- Deviations:
- yes
- Remarks:
- calibration
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed on 09 June 2008
- Type of method:
- oscillating densitimeter
- Dynamic viscosity of test material:
- (no data)
- Key result
- Type:
- relative density
- Density:
- 0.875 other: relative density is unitless
- Temp.:
- 20 °C
- Conclusions:
- The substance is much less dense than water.
- Executive summary:
The density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, oscillating densitimeter 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 density of the test item has been determined to be 0.8749 g/cm3 at 20.0°C and the relative density (D20/4) is 0.8749.
Reference
Measured values : 0.8749 g/cm3 and 0.8749 g/cm3, at 20.0°C
Mean: 0.8749 g/cm3
Relative density: 0.8749
Description of key information
The substance is much less dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.875
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Despite minor restrictions due to technical inaccuracy, it is considered as a key study. The result is retained as key data.
Note that this parameter may show some variations, due to the UVCB nature of the substance.
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).
