- Executive summary:
A study was conducted to determine the surface tension of the substance according to a method similar to OECD Guideline 115 and EU Method A.5. The test substance was dissolved into water (1 g/L), conditioned for 10 min in an ultrasonic bath and tempered at 20°C. The automatic measurement was then initiated. The practical test performance was based on the in-house test procedure 34N10001.01: "Determination of Surface Tension of aqueous solutions". Two different solutions with a concentration of 1 g/L were prepared. The surface tension should be measured, if the solution was in equilibrium state. The solution in the measuring vessel was approximately in equilibrium, if the measured surface tension was nearly constant. An average of 6 single measurements was determined per solution. In this case, the total measuring time was more than 1200 s per solution. Both solutions were in an equilibrium state after approx. 4000 and 5500 s. Under the study conditions, the surface tension of the substance was determined to be 41.0 mN/m at concentration of 1 g/L (Kintrup, 2016).
