Key result
Surface tension:
67.1 mN/m
Temp.:
20 °C
Conc.:
1 g/L

An aqueous solution of the test item in de-ionized water with a concentration of 1.0 g/l was prepared and treated for 30 minutes at 25 ± 0.5 °C by ultrasound. After solving and tempering at 20 ± 0.5 °C for 2 hours, the measurement of the surface tension with the test item was carried out at 20 ± 0.5 °C.

Mean value:   = 67.08 mN/m 


Du to the fact that the surface tension is higher than 60 mN/m, the test item has no surface-active properties. 

Conclusions:
The surface tension of the aqueous solution at 20 °C is 67.1 mN/m.

Description of key information

67.1 mN/m at 20 °C
