Applicant's summary and conclusion

Conclusions:
The mean surface tension of 90% saturated solutions of test itemFRET 11-0571) in water has been determined to be 48.5 mN/m at 20.0 ± 0.5 °C. The test item was considered to be surface-active.

Executive summary:

The Surface Tension of FRET 11 -0571 has been determined to be 48.5 mN/m at according to OECD TG 115 (Surface Tension of Aqueous Solutions) using XXX method. According to EU method A5, the substance is considered to be surface active because the value is less than 60 mN/m under the conditions of this method
