Applicant's summary and conclusion
- Conclusions:
- The mean surface tension of duplicate 90 % saturated solutions of test item in water has been determined to be 37.9 mN/m at 21.5 ± 0.5 °C. The test item was considered to be surface-active.
- Executive summary:
The determination was carried out by a ring method, using a procedure 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 the Testing of Chemicals, 27 July 1995.
Conclusion
The mean surface tension of duplicate 90 % saturated solutions of test item in water has been determined to be 37.9 mN/m at 21.5 ± 0.5 °C. The test item was considered to be surface-active.
