The measured values showed no time dependence.

Mean value: 72.3 mN/m

Mean value with calibration factor: 72.8 mN/m

The test item is not a surfactant.

Conclusions:
A surface tension value of 72.8 mN/m (c=1.0 g/L, at 20.0 °C) was determined in a reliable study conducted according to EU method A. 5. The test item is not classified as surfactant.
Executive summary:

A surface tension value of 72.8 mN/m (c=1.0 g/L, at 20.0 °C) was determined in a reliable study conducted according to EU method A.5. The test item is not classified as surfactant.

Description of key information
