The mean surface tension of the aqueous preparation of the test item (c = 0.66 g/L) at 20 °C was found to be 42.9 mN/m. The test item is surface-active.
A curve was plotted taking the surface tension values as ordinates and the logarithms of the concentrations (in g/L) was abscissae. The CMC would correspond to the point of the curve at which a sharp change of slope occurs. This could not be observed. Therefore, a CMC could not be determined.
It was tried to produce a stock solution with a higher amount of the test item following the procedure described above. The test item was warmed up for 30 min at 80 °C in a drying cabinet. Then 2.1885 g of test item were weighed out and filled to 1000 mL with deionized water (concentration = 2.2 g/L). Also this stock solution was stirred at 49 – 51 °C for 24 h. But after this procedure the test item was visually not completely dissolved. As the highest tested concentration was closed to the maximum solubility of the test item, no further test concentrations were investigated.
After discussion with the study monitor, it was decided to stop the experiments.
Conclusion
The mean surface tension of the aqueous preparation of the test item (c
= 0.66 g/L) at 20 °C was found to be 42.9 mN/m. The test item is surface
active.
The critical micellar concentration (CMC) of the test item could not be determined with the ring method acc. to ISO 4311:1979 an under the test conditions used. No further test concentrations were investigated as the highest tested concentration was close to the maximum solubility of the test item.
