Conclusions:
The test substance is considered to be surface active (surface tension <60 mN/m).

Description of key information

31.9 mN/m (90% satuarated aqueous solution at 20°C) (OECD 115, EC A.5)

Key value for chemical safety assessment

Additional information

Surface tension 31.9 mN/m at 20 °C and 90% saturated aqueaous solution.


The test substance is considered to be surface active (surface tension <60 mN/m).
