Description of key information

The substance has a surface tension of 51 mN/m. The critical micelle concentration (CMC) was determined at 22.1 mg/L at 20.1oC.

Key value for chemical safety assessment

Surface tension:
51

Additional information

The surface tension study was renewed in 2014 to adapt the concentration limits. The surface tension of an aqueous preparation of the test item (90% saturation concentration) at 20°C was found to be 51 mN/m. The estimated accuracy is ± 1 mN/m.

The test item is surface-active. The surface tension was determined according to OECD Guideline for the Testing of Chemicals 115 Surface Tension of Aqueous Solutions“. The Critical Micellization Concentration (CMC) of the test item was determined to be 22.1 mg/L at 20.0 °C ± 1.0 °C.
