- 72.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of an aqueous solution of the test item (1 g/L) was determined to be: 72.4 mN/m at 20 °C ± 0.5 °C.
- Executive summary:
The purpose of the study was to determine the surface tension of an aqueous solution of the test item by means of a ring tensiometer. The test was performed in accordance with OECD test method no. 115. The surface tension of an aqueous solution of the test item (1 g/L) was determined to be 72.4 mN/m at 20 °C ± 0.5 °C. Based on the results of this study, the test item does not need to be regarded as surface active material.
