Surface tension:
72 mN/m
Temp.:
20.3 °C
Conc.:
1 g/L

The mean surface tension of the test item at 1 g/L in demineralized water was: 72.0 +/- 0.2 mN/m (corrected value).

Conclusions:
The mean surface tension of the test item at 1 g/L in demineralized water was: 72.0 +/- 0.2 mN/m (corrected value).
The test item was not considered as surface-active in the experimental conditions.
