Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)

- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)

- Density:
- 1.299 g/cm³
- Temp.:
- 20 °C
- Remarks on result:
- other: This value is the mean of two independent determinations with the maximum error of a single determination. Standard deviation was 0.0030 g/cm3, showing good correlation of the two determinations.
- Conclusions:
- Density = 1.2988 ± 0.0007 g/cm3 at 20 ± 0.4 °C;
Relative density = 1.2988 at 20 °C.
The study was performed according to OECD TG109 and EU Method A.3 without deviations and therefore reliability of Klimisch 2 has been assigned. - Executive summary:
The density of the test substance was determined in a non-GLP test according to OECD 109 resp. EU A.3. Using the pycnometer method, a density of 1.2988 ± 0.0007 g/cm3 at 20 ± 0.4 °C was measured; the relative density of the test substance has the same number value, but no unit. This value is the mean of two independent determinations with the maximum error of a single determination (see table below). Standard deviation was 0.0030 g/cm3, showing good correlation of the two determinations.

Description of key information
A density of 1.2988 ± 0.0007 g/cm3 at 20 ± 0.4 °C was measured; the relative density of the test substance has the same number value, but no unit. This value is the mean of two independent determinations with the maximum error of a single determination. Standard deviation was 0.0030 g/cm3, showing good correlation of the two determinations.

Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
