Description of key information

The surface tension of the substance in water is 46.7 mN/m at 20°C, according to DIN EN 14370, which is equivalent to the EU Method A.5 (Surface Tension).

Key value for chemical safety assessment

Surface tension:
46.7
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The surface tension at 20 °C of a solution of the test substance in demineralized water with a concentration of 1 g/l, was determined by the plate method using a tensiometer. The following result of 46.7 mN/m at 20 °C was received. For verification of the measured values demineralized water is also measured. With a correspondence of the measured value (20 °C) = 72.7 mN/m, to the theoretical value (20 °C) = 72.75 mN/m, cited in literature, the determination of the surface tension of the test item is considered as valid.
