Conditions of micellar dissolution to soluble surfactants are discussed. Simple and pictorial conditions for micellar dissolution are as follows: (1) the surfactant in the presence of a solvent has to be in the liquid state so that the solvent dissolves in the surfactant phase; (2) the solubility of solvent in the surfactant phase has to be infinite so that the surfactant disperses forming micelles, otherwise a 2-phase solution is obtained; (3) the saturation concentration of surfactant in the solvent has to be small so that the micelles are thermodynamically stable above the saturation concentration of molecular dispersion. These criteria are equally valid for water-soluble polymers such as proteins. 16 references.
