Description of key information

The surface tension of the test substance is 71.6 mN/m at 21 °C and a concentration of 0.884 g/l.

Key value for chemical safety assessment

Surface tension:
71.6
in mN/m at 20°C and concentration in mg/L:
884

Additional information

A GLP study was conducted in accordance with the OECD Guideline for the Testing of Chemicals. 15 „Surface Tension of Aqueous Solutions" by the ring method using a surface tension torsion balance.

The study determined the surface tension of an aqueous preparation of the test item (0.884 g/l) at 21 °C to be 71.6 mN/m.

Therefore the substance is regarded not to be surface active.
