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.
