Results and discussion

Surface tension
Surface tension:
32.2 mN/m
Temp.:
25 °C
Conc.:
1 g/L

Any other information on results incl. tables

Individual results of duplicate measurements were:

#1       38.54 ± 0.23 mN/m.

#2       37.19 ± 0.07 mN/m

Taking into account the different values and their nominal uncertainty, the uncertainty of the mean value (37.9 mN/m) is estimated as 0.8 mN/m.

Applicant's summary and conclusion

Conclusions:
The surface tension of a 1 g/L aqueous solution of the test substance is 37.9 ± 0.8 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 37.9 +/- 0.8 mN/m.
