90 vol%
Remarks on result:
other: The mean surface tension of a duplicate solutions, prepared as 90 % saturated solutions of test item in water, has been determined to be 57.5 mN/m at 20.0 ± 0.5 °C.
Conclusions:
The mean surface tension of a duplicate solutions, prepared as 90 % saturated solutions of test item in water, has been determined to be 57.5 mN/m at 20.0 ± 0.5 °C. The test item was considered to be surface-active
Executive summary:

57.5 mN/m (90% saturated aqueous solutions) at 20.0 ± 0.5 °C, using a ring method 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 Testing of Chemicals, 27 July 1995. The test item was considered to be surface-active.
