Results and discussion

Surface tension
Key result
Surface tension:
< 60 mN/m
Remarks on result:
other: temperature not given; results for all tested concentrations: from 8.39 mg/L to 92.40 mg/L.

Any other information on results incl. tables

The surface tension is found below 60 mN/m for each tested concentrations (from 8.39 mg/L to 92.40 mg/L).

Applicant's summary and conclusion

Conclusions:
The surface tension of the substance is found below 60 mN/m, consequently the substance is considered to have surface-active properties.
