Description of key information

Dilute solutions:
65mN/m at 2g/l
51mN/m at 11.8g/l

Key value for chemical safety assessment

Surface tension:
65
in mN/m at 20°C and concentration in mg/L:
2 000

Additional information

The key parameter is a measured result at a slightly higher concentration than normally required according to the OECD protocol but the data is sufficient to establish that whilst the substance has some surface activity it is not sufficient to confound the measurement of other physicochemical or ecotoxicological parameters.
