Description of key information
0.8956 g/cm³ at 20 °C (OECD 109, oscillating densitimeter)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.9
Additional information
A very close value of 0.8975 g/cm3 was also reported in an experiment employing Staubinger viscometer at 40 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
