Anionic Hydrocarbon SDS – Anionic Hydrocarbon SDeS

Binary Mixtures



CMC and micelle composition for binary mixtures of anionic sodium dodecyl sulfate (SDS) and sodium decyl sulfate (SDeS) plotted as functions of the composition of the unaggregated (monomeric) surfactant present in the solution.  The points are experimental results from literature and the lines are results predicted a priori by molecular theory.

 

 

 

Anionic Hydrocarbon SDeS – Anionic Fluorocarbon SPFO

Binary Mixtures


CMC for binary mixtures of anionic sodium decyl sulfate (SDS) and sodium perfluoro octanoate (SPFO) plotted as functions of the composition of the unaggregated (monomeric) surfactant present in the solution.  The points are experimental results from literature and the lines are results predicted a priori by molecular theory.  The results show that anionic hydrocarbon rich mixed micelles and anionic fluorocarbon rich micelles are formed at the two composition extremes while both of these types of micelles coexist in intermediate composition range. This phenomenon has been referred to as micelle demixing.
