- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:

- Type of method:
- ring method
- 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.
- 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.
