The mean density of the two test series is: 1.55 g/cm3.
Conclusion: The relative density of the test item at ambient temperature (compared to water at 4 °C) was found to be:
D4R= 1.55 (20.3 °C).
Description of key information
Relative density: 1.55 at 20.3 °C (OECD 109, air comparison pycnometer).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.55
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
