Description of key information

The surface tension of the test substance was determined to be 66.8 mN/m (1.04 g/L solution) at 21.2 ± 0.5°C, using a ring method based on ISO 304, designed to be compatible with EC test method A.5, under GLP conditions (Butler and White, 2010). The test item is considered not to be surface-active.

Key value for chemical safety assessment

Surface tension:
in mN/m at 20°C and concentration in mg/L:
1 040

Additional information

Although the temperature of measurement was slightly above 20.0 °C, this is not considered to influence the test result significantly.
