Description of key information

Surface tension: 58.1 mN/m at 19.6 °C ± 0.5 °C. Because of the poor solubility at 20°C, a 90% saturated solution was used. 

Key value for chemical safety assessment

Surface tension:

Additional information

Substances showing a surface tension lower than 60 mN/m should be regarded as being surface-active. However, analysis of the 90% saturated solution found no test item detected above the limit of detection. It is possible that the test item had undergone reaction to the corresponding acid during the saturation period. Therefore, it was concluded that the test item and/or degradation products were considered to be surface-active.
