Description of key information
The vapour pressure was determined for the substance with the isothermal thermogravimetric effusion method. The vapour pressure is lower than that of the reference compound chrysene: < 8.4E-07 Pa at 20 °C and 1.3E-06 Pa at 25 °C.
For risk assessment the vapour pressure is set at 1E-06 Pa at 20°C (minimum value in EUSES)
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
