Results and discussion

Surface tension

Surface tension:

26.5 mN/m

Temp.:

25 °C

Conc.:

1 g/L

Any other information on results incl. tables

Individual results of duplicate measurements were:

#1       26.51 ± 0.05 mN/m.

#2       26.58 ± 0.05 mN/m

Taking into account the different values and their nominal uncertainty, the uncertainty of the mean value (26.5 mN/m) is estimated as 0.1 mN/m.

Applicant's summary and conclusion

Conclusions:

The surface tension of a 1 g/L aqueous solution of the test substance is 26.5 ± 0.1 mN/m at 25 °C.

Executive summary:

The surface tension of the test substance was determined according to the OECD Guideline 115 using the plate method. At 25 °C, the surface tension is 26.5 +/- 0.1 mN/m.
