Applicant's summary and conclusion

Conclusions:

The surface tension of a 90 % saturated solution of test item in water has been determined to be 68.9 ± 1.0 mN/m at 21.2 ± 0.5 °C. The test item was considered to be not surface-active.

Executive summary:

The determination was carried out by a ring method, using a procedure designed to be compatible with that specified in Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995.

Conclusion

The surface tension of a 90 % saturated solution of test item in water has been determined to be 68.9 ± 1.0 mN/m at 21.2 ± 0.5 °C. The test item was considered to be not surface-active.
