I use anionic surfactant and glycolipids (nonionic surfactant), I mixed them as one solution. I make a dilution. But here, how can i assume the expected CMC (not too accurate, just approximate) of the mixed surfactant ??
I also use tensiometer to determine the CMC.
Thank you
The CMC of the mixed micelles, in most of the cases, falls between the CMC’s of pure components, but sometimes it may fall below or rise even above the CMC of either of the individual surfactants. So it depends on the chosen system. Please refer M. J. Rosen, Surfactants and Interfacial Phenomenon, Wiley Intersciences, New York, 2004 for more details.
You can expect CMC of mixed system by using Clints Model. For further assistance check this article.Article Physicochemical investigation of novel biodegradable dicatio...
