Results and discussion

Surface tension
Surface tension:
71 mN/m
Temp.:
20 °C
Conc.:
1 g/L

Any other information on results incl. tables

Overall mean calibration corrected surface tension = 72.0 mN/m

Harkins-Jordan corrected value = 71.0 mN/m

Applicant's summary and conclusion

Conclusions:
The surface tension of a 1 g/L aqueous solution of the test substance was found to be 71.0 mN/m. As the result was greater than 60 mN/m, the test substance was not considered to be surface active.
