Additional information

One reliable experimental study is available and is selected as key study (NOTOX B.V., 2004f). It was performed according to the OECD 115 guideline and EC A5 method and under GLP conditions. The surface tension of an aqueous cesium potassium fluoroaluminate solution at a 90% saturated concentration is 72.1 mN/m at 20.0 ± 0.5°C. Based on the criteria as outlined in the guideline, cesium potassium fluoroaluminate should not be considered as a surface active material.
