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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The vapour pressure determined with the vapour pressure balance method was 1.35 x 10-9 hPa at 25°C (Bayer, 1992).
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 25 °C
Additional information
Gas saturation method delivered another result of <2.27 x 10-6 hPa at 25°C (Monsanto, 1980). Although this is about 1000 times higher than the one mentioned in key study, these two results are both far below 1 Pa indicating a very low vapour pressure.
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).
