Additional information

The surface tension of the test item was assessed in accordance with the OECD 115. During the ring test, the surface tension recorded showed a time-dipendence and no mean value could be reported. The reported surface tension refers to the last of the six measurements. First measurement reported a surface tension of 46.67 mN/m. However, it could be stated that the surface tension of the test item was lower than 60 mN/m and the substance presented surface-active properties.
