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
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.

Description of key information
