Conclusions
The density of the test item was determined to be 1.102 g/cm3 (1.102E+03 kg/m3) at 20.1 °C ± 0.1 °C using a gas comparison pycnometer.
Description of key information
Relative density: 1.1 at 20 °C (OECD 109, gas comparison pycnometer)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.1
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
