Description of key information

Surface tension: 45.1 mN/m at the saturation concentration (given as 1.0 g/l)
According to the Council Regulation (EC) No 648/2004 the substance can be regarded as surface active material.

Key value for chemical safety assessment

Surface tension:
45.1
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

A surface tension of 45.1 mN/m at the saturation concentration (given as of 1.0 g/l) is reported in a reliable study, conducted according to an appropriate EU test protocol and in compliance with GLP; this is the most reliable result and is assigned as key study.

A water solubility of 1.0 g/l was determined in this study, different than the 0.85g/L obtained in the key water solubility study. It is assumed that hydrolysis effects, which have been observed in the surface tension study, are responsible for the deviation.
