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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results
Two tests with different amounts of the test item were performed to determine the relative density at a temperature of 20 °C ± 0.01 °C. The results are summarized in the following table
Test No. |
Temperature [°C] |
Amount of test item [g] |
Average sample volume [cm³] |
Density [g/cm³]* |

* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.
The mean density of the test item at 20 °C is 1.4097 g/cm³. The relative density is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).
The relative density is D420 = 1.410.
Final Results
According to OECD Test Guidelines 109 (2012) and Regulation EC No. 440/2008 Part A. Method A.3., the relative density of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) is 1.410.
Description of key information
Relative density: 1.41 at 20 °C (EU Method A.3, air comparison pycnometer)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.41
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).
