Applicant's summary and conclusion

Executive summary:

The determination of the surface tension of the test item in solution was performed according to Regulation (EC) n°440/2008, A.5 and to the OECD Guideline n° 115.

The mean surface tension of the test item in solution at 2 mg/l in distilled water at 19.9 °C is 71.6 mN/m ± 0.2 mN/m. The test item was not considered as surface-active in the experimental conditions used.
