Applicant's summary and conclusion

Executive summary:

The surface tension was measured according to the OECD 115 method.

The surface tension of the test item aqueous solution read on the instrument was 70.80 mN/mat 21±0.5 °C using the ring method representing the mean of five separate measurements.

As the surface tension value was higher than 60 mN/m, the test substance is not classified as surface active.
