- Conclusions:
- The mean surface tension of duplicate 90 % saturated solutions of test item in water has been determined to be 71.3 mN/m at 20.0 ± 0.5 °C. The test item was considered not to be surface-active.
- Executive summary:
71.3 mN/m (duplicate 90 % saturated solutions of test item in water) at 20.0 ± 0.5 °C, using a ring method, designed to be compatible with Method A5 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 not to be surface-active.
