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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 931-195-9 | CAS number: -
Vapour pressure
Administrative data
Link to relevant study record(s)
Description of key information
7 Pa at 20 C reported, but considered due to impurity present when original testing performed. Modelling suggests insignificant vapour pressure at room temperature.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
High vapour pressure apparently due to propylene carbonate impurity in the material tested for the original notification. This impurity is not present in the substance covered by this registration. Insufficient data has been provided by ECHA under the 12 year rule to make a suitable conclusion. Estimates based on modelling would suggest a very low vapour pressure of no significicance.
EPISuite suggests a vapour pressure of < 1 X 10 -6.
The results of modelling the main component are :
VP(mm Hg,25 deg C): 1.34E-014 (Modified Grain method) VP (Pa, 25 deg C) : 1.79E-012 (Modified Grain method) Subcooled liquid VP: 1.4E-013 mm Hg (25 deg C, Mod-Grain method) : 1.86E-011 Pa (25 deg C, Mod-Grain method)
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.
