Additional information

The water solubility of Undecylenamidopropyl Betaine was addressed by determination of the critical micelle concentration (CMC) via measurement of the surface tension according to OECD Guideline 115 (1995). The CMC was determined by measuring the surface tension of the test item in a concentration range of 0.5 -10 g/L.

The water solubility, expressed by the CMC was determined to be 3.1 g/L at 20°C.
