Description of key information

The surface tension of a 1.0 g/L solution of test item in water has been determined to be 51.4 mN/m at 20.6 ± 0.5 °C. The test item is considered to be surface active.

Key value for chemical safety assessment

Surface tension:
51.4
in mN/m at 20°C and concentration in mg/L:
1

Additional information

The test solutions were clear, colorless solutions containing no excess, undissolved test item. As each (corrected) surface tension value was within 0.5 mN/m of the mean (corrected) value, the mean (corrected) value was considered to be acceptable as the endpoint of the test.
