Results and discussion

Surface tension
Surface tension:
64.43 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Remarks on result:
other: Due to the fact that the surface tension is higher than 60 mN/m, the test item has no surface-active properties.

Applicant's summary and conclusion

Conclusions:
Under the described conditions the aqueous solution of the test item, cobalt bis(2-ethylhexanoate), at 20°C is sigma = 64.43 mN/m. In conclusion, the test item has no surface-active properties.
