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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Measured value of the aqueous solution:
21.8 hPa at 20°C
- Calculated value of the main component:
0.43 hPa at 20°C
Key value for chemical safety assessment
- Vapour pressure:
- 0.43 hPa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure of the aqueous solution was determined by static method according to OECD Guideline 104 and the calculation was using the software SPARC.
As the test substance is UVCB therefore the vapour pressure values of the individual component (calculated and literature values) were reviewed and evaluated. It is reasonable no doubt that the measured value of the aqueous solution is likely related to vapour pressure of the water (23 hPa at 20°C).
The vapour pressure of the main component was calculated to be in the range from 0.00 to 0.43 hPa at 20°C. It can be suggested that the value of 0.43 is considered to be as worse-case and is used for the CSA.
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.
