key study
Study period:
2010-04-20 to 2010-04-20
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
GLP compliance:
no
Type of method:
ring method
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.
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.

Additional information

The surface tension of cobalt bis(2-ethylhexanoate) was determined according to OECD guideline 115, ring method. Six measurements at a temperature of 20 +/- 0.5 °C were performed every minute with the test item. 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.
