- Key result
- Surface tension:
- 71.9 - <= 72.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 000 mg/L
- Conclusions:
- From the experimental data obtained according to the guideline A.5 in Official Journal L 383 Part A, it can be concluded that the surface tension of the aqueous solutions at concentrations of 1 g/L, 0.5 g/L, 0.1 g/L, at 20°C are 71.9, 72.7, 72.7 mN/m respectively.
According to the interpretation of the results suggested in the A.5 official method, the test substance should be regarded as a non surface-active material.
