Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

20 °C

Additional information

There is not data available for the UVCB substance itself. Measured data is available for the lowest molecular weight main component, 2-(2-(2-ethoxyyethoxy)ethoxy)ethanol, indicating that the vapour pressure at 20C would be approximately 1Pa. A reliable QSAR predicts a similar value for the vapour pressure of this same substance and that the higher molecular weight main component, not surprisingly, has a much lower vapour pressure. On the reasonable assumption that the lower molecular weight main component will dominate the vapour pressure, the measured vapour pressure for 2-(2-(2-ethoxyethoxy)ethoxy)ethanol will be used to derive the key parameter for this end point.
