Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The surface tension of the test item in aqueous solution was determined in a guideline study according to OECD guideline 115 applying the plate method. The surface tension of Tetraglyme was determined to be 66.7 ± 0.5 mN/m at a concentration of 1 g/L and 20 °C.

Additional literature data from a peer reviewed journal are available on surface tension for the pure, undiluted substance.
