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.
