Applicant's summary and conclusion
- Conclusions:
- The surface tension of a 90 % saturated solution of test item in water has been determined to be 36.0 mN/m at 21.8 ± 0.5 °C. The test item was considered to be surface active.
- Executive summary:
The surface tension of a 90 % saturated solution of test item in water has been determined to be 36.0 mN/m at 21.8 ± 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 to be surface active.
