Results
Two test with different amounts of test item were done to determine the
relative density D420 at a temperature of 20 ±
0.01 °C. Table 1 shows the results obtained.

*The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation of ≤0.2%.
The mean density of the test item at 20 °C is 1.17234 g/cm3. The relative density is calculated by dividing the test item’s density by that of water at 4 °C. Hence, the relative density is: D420= 1.17
Description of key information
Relative Density: 1.17 at 20 °C (OECD 109, pycnometer method).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.17
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
