Results and discussion
Surface tension
- Surface tension:
- 71.14 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 di(acetate) tetrahydrate, at 20°C is sigma = 71.1 mN/m. In conclusion, the test item has no surface active properties.
