Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Key result
- Type:
- relative density
- Density:
- 1.48
- Temp.:
- 20 °C
- Remarks on result:
- other: corresponding to 1.48 g/cm^3
- Conclusions:
- Relative density D20/4 (OECD 109): 1.48
- Executive summary:
In a reliable study performed compliant with GLP according to OECD 109, the density of the test item at 20 °C was determined using the gas comparison pycnometer method. From two test series, the following results were obtained:
Measurement 1: Rho_p20 = 1.4766 g/cm^3;
Measurement 2: Rho_p20 = 1.4762 g/cm^3;
giving a rounded mean value of 1.48 g/cm^3.
The relative density D20/4 was calculated based on a density of water at 4 °C of 1.000 g/cm^3:
D20/4 = 1.48
Reference
Two test series were performed at 20.0 °C. The results are summarized in the following table:
