Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Values at 20C: 9.7-10.3, 9.7, 9.8, 9.83 (kPa)
Values at 21C: 10.4kPa
Values at 22.2C: 113.1kPa
Values at 25C: 12.2, 12.6, 12.67kPa
Values at 27C: 13.3kPa
Key value for chemical safety assessment
- Vapour pressure:
- 10.3 kPa
- at the temperature of:
- 21 °C
Additional information
A number of consistent value are reported for the vapour pressure across a variety of secondary sources indicating a vapour pressure of around 9.7 - 10.3kPa at around 20C. Because of the impact on exposure assessment (the cut off between medium and high fugacity bands as used in ECETOC TRA exposure prediction tool) a conservative choice of 10.3kPa is selected as the key parameter for this end point.
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.
