- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)

- Key result
- Surface tension:
- 30 mN/m
- Temp.:
- 20 °C
- Conc.:
- 0.01 vol%
- Conclusions:
- The surface tension is 30.0 mN/m at room temperature and a substance concentration of 0.01%.
- Executive summary:
The surface tension of the test substance was determined according to OECD guideline 115 and EU method A.5. The critical micelle concentration was also determined.
1 g/L prepared in purified water, was used to determine the surface tension.
