Key result
Surface tension:
50.8 mN/m
Temp.:
20 °C
Conc.:
1.1 g/L
Conclusions:
The surface tension of a nominally 1.0 g/L solution of test item in water has been determined to be 50.8 ± 0.5 mN/m at 20.4 ± 0.5 °C.
The test item was considered to be surface-active.
Executive summary:

Surface Tension. 50.8 ± 0.5 mN/m (mean of duplicate, nominally 1.0 g/L solutions) at 20.4 ± 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.
