Conclusions:

The mean surface tension of test item in water has been determined to be 69.7 mN/m at 20.8 ± 0.5 °C. The test item was considered to be surface-active.

Executive summary:

The surface tension of 90 % saturated solutions of test item in water have been determined to be 69.7 mN/m at 20.0 ± 0.5 °C, using a ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.  The test item was considered to be not surface-active.

Description of key information

The mean surface tension of test item in water has been determined to be 69.7 mN/m at 20.8 ± 0.5 °C.  The test item was considered to be surface-active.
