Conclusions:
Under the study conditions, the surface tension of the test substance was 59.84 mN/m at 20°C.
Executive summary:

A study was conducted to determine the surface tension of the test substance using a calibration weight method. An aqueous solution of the test substance with a concentration of 1.0 g/L was prepared at ambient temperature. Seven measurements at a temperature of 20°C were carried out. Under the study conditions, the surface tension of the test substance was 59.84 mN/m at 20°C (Hamacher, 1986).

Description of key information

The surface tension was determined using a calibration weight method (Hamacher, 1986).

Key value for chemical safety assessment

Surface tension:
