Description of key information

15.2 mN/m related to commerical solution diluted in deionized water.

Key value for chemical safety assessment

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

Additional information

The surface tension at different concentrations of the commercial solution of the test item was investigated through the Wilhelmy Plate method, using semi-automatic tensiometer EasyDyne K20 (Kruss GmbH). The surface tension for the commercial solution of the test item diluted at a concentration of 0.1 % (1g/l) in deionized water was found to be 15.2 mN/m (at 25 °C).
