Description of key information
In accordance with the standard Column 2 adaptation as set out in Section of 7.5 REACH Annex VII, it is considered justified to omit the testing to determine the vapour pressure of the substance on the basis of the high melting point of the substance.
For the chemical safety assessment, a vapour pressure of 1E-06 Pa (at 25˚C) was assumed to allow for the Chesar model to work properly. This value was chosen as it is the lowest vapour pressure suggested in EUSES.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
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.
