Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Information on TEGME: cited melting points: -44, -75C

Information on TetraEGME (main component of multi-constituent substance: -26, -39C

No data on PentaEGME. However, it is likely to behave as a solute in 'solvent' TetraEGME and, with the latter the dominant component, the melting point is likely to be close to TetraEGME.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C

Additional information

Based on the data available from read across sources and components of this multi-constituent substance, it is reasonable to predict that this substance itself will have a melting point of <-20C.
