Results and discussion
- Results:
- CMC was determined from the plot of the surface tension of the test solutions as function of log C based on the interception of 2 trendlines from the test solutions with nominal test item concentrations of 10.3, 35.0 and 100.0 mg/L and from the test solutions with nominal test item concentrations of 1005.0, 3007.0 and 10006.7 mg/L (mean values).
The intersection was calculated to be log C = 2.71. It corresponded with a CMC of 510 mg/L.

Applicant's summary and conclusion
- Conclusions:
- The critical micelle concentration of the substance is 520 mg/L
- Executive summary:
The CMC was determined by measuring the surface tension of test substance solutions at different concentrations. No further decrease of surface tension was measured at 520 mg/L (extrapolated value).
