“…The experimental setup and results have been described elsewhere. , The investigation discovered a maximum of the evolution time near the critical micelle concentration (cmc) for the foam prepared from the sodium dodecyl sulfate (SDS) solution (Figure ). Similar observations of peaks of the foam stability were still earlier reported in the literature , as obtained by traditional measuring the foam-column height decrease in time. However, the explanation has not been given so far and remains to be a challenge to theory.…”

“…As the film elasticity modulus is responsible for the foam stability, one can expect a maximum of foaminess and the foam stability near the critical micelle concentration. Observations of this kind were reported previously, [7][8][9][10][11] but no explanation of this phenomenon was given until now. We can see that the above theory satisfactorily explains the existence of maxima for foaminess and foam stability.…”

“…Considering a film as an incompressible condensed system, volumes n i are assumed to be constant. In this approximation, concentration c j can be excluded from independent variables, and, accounting for (7), the known thermodynamic expression for the chemical potential differential can be written as Putting (12) in (10) leads to the expression where is evident to be the total film thickness (including adsorbed layers at the two equimolecular surfaces). In the above approximation, the total film volume Ah t is constant, which yields the additional [to equation (3)] relationship…”
