Results and discussion

Surface tension
Surface tension:
65.5 mN/m
Temp.:
20 °C
Conc.:
90 other: % saturation (approx. 135 mg/L)

Any other information on results incl. tables

The Harkins-Jordan corrected value was calculated to be 64.0 mN/m.

Applicant's summary and conclusion

Conclusions:
The surface tension of a 90% saturated aqueous solution of the test substance was found to be 64.0 mN/m. As the result is greater than 60 mN/m, the test substance was not considered to be surface active.
