Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Density:

- Temp.:
- 20 °C
- Conclusions:
- The density of the substance was found to be 2.05 g/cm3 at 20 °C.
- Executive summary:
The density of the substance was determined under GLP in accordance with OECD TG 109 (October 2012). The test item was melted and homogenised at a nominal temperature of 40 °C before use. The determination of the density was carried out using a gas comparison pycnometer. After the calibration of the instrument, an empty glass vessel of known mass was placed in the sample cell and triplicate pressure readings were taken after pressurising the reference cell of known volume and then switching to the sample cell. From the obtained data, the volume of the glass vessel could be calculated. The procedure was then repeated with the glass vessel containing a known amount of the test substance. Triplicate pressure readings were taken after pressurising the reference cell of known volume and then switching to the sample cell containing the test substance. Both procedures were performed in triplicate. From the difference between the two calculated volumes, the volume of the test substance alone could be determined and the density could then be calculated taking into consideration the known mass of substance placed in the glass vessel.
