Description of key information

The surface tension was conducted using the ring Method which is a part of EU Method A5 of Directive 84/449/EEC. The surface tension of a 90% saturated aqueous solution of the test material has been determined as 73.0 mN/m at 20°C.

Key value for chemical safety assessment

Surface tension:
73

Additional information

The surface tension was conducted using the ring Method which is a part of EU Method A5 of Directive 84/449/EEC. The surface tension was measured at intervals until a constant reading was obtained at least three times in succession. The reading was taken at the maximum force required to detach the ring from the liquid surface. The surface tension of a 90% saturated aqueous solution of the test material has been determined as 73.0 mN/m at 20°C.

Substances showing a surface tension lower than 60 mN/m should be regarded as being surface active. Therefore, the test substance is not considered to be surface active.
