Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 07 March 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method. Test substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- 2012
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- 2008
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- no
- Type of method:
- oscillating densitimeter
- Key result
- Type:
- relative density
- Density:
- 1.016 other: no dimension
- Temp.:
- 20 °C
- Conclusions:
- The relative density of test item is 1.0165 +/- 0.0001 at 20.00 +/- 0.01°C.
This is a mean of two measurements. - Executive summary:
The relative density of test item was determined using the oscillating densitometer method as described in OECD 109 (2012), resp. EU A.3. (2008).
The relative density of test item was determined to be 1.1065±0.0001 at 20 °C. This is a mean of two determinations.
Reference
The results are presented in the following Table 1.

Duplicate determinations are within the accuracy of the method (+/-0.0001 g/cm3), therefore no additional measurement is required, and the mean value is retained.
Description of key information
The relative density of test item was determined to be 1.0165 ±0.0001 at 20°C.
This is a mean of two determinations.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.016
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC method, is available. It is considered as a key study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
