Description of key information

The test item has a mean surface tension of 67.18  mN/m.

Key value for chemical safety assessment

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

Additional information

Study conducted to EU test guidance 92/69/EEC part A5 using the ring method in compliance with GLP.

The mean value, multiplied by the calibration factor yields: WF = W x F = 67.18 mN/m

As the surface tension is higher than 60 mN/m, the test item has no surface-active properties.
