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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15.09.15
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- GLP compliance:
- no
- Type of method:
- pycnometer method
- Key result
- Type:
- relative density
- Density:
- 2 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be 2.00.
- Executive summary:
A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD TG 109 by using the gas comparison pycnometer at 20 °C. Two tests were performed and the density of the test item was determined. The relative density of the test item (calculated from the mean density of the test item) was determined to be D420= 2.00.

Description of key information
A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD TG 109 by using the gas comparison pycnometer at 20 °C. Two tests were performed and the density of the test item was determined. The relative density of the test item (calculated from the mean density of the test item) was determined to be D420= 2.00.
Key value for chemical safety assessment
- Relative density at 20C:
- 2
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.
