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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 310-288-2 | CAS number: 161907-78-4 A complex mixture of oxygenated hydrocarbons produced by the distillation of residues from the manufacture of ethylene glycol monoethyl ether. It consists predominantly of a mixture of di-, tri-, tetra- and pentaethylene glycol monoethyl ethers having carbon numbers predominantly in the range C6 to C12 and boiling in the range of approximately 200°C to 300°C (392°F to 572°F).

Description of key information
2-(2-(2-ethoxyyethoxy)ethoxy)ethanol: 1.15Pa @ 20C estimated from Antoine constants measured at elevated temperature. 1Pa @20C (QSAR)
2-(2-(2-ethoxyethoxy)ethoxy)ethanol: QSAR prediction 0.3Pa @ 20C
3,6,9,12-tetraoxatetradecan-1-ol: QSAR prediction 0.012Pa @ 20C
Key value for chemical safety assessment
- Vapour pressure:
- 1 Pa
- at the temperature of:
- 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.
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.
