Critical micelle-formation concentrations and Kraft points of sodium monoalkyl sulfosuccinates homologues from C10 to C14 are determined by conductometry. Degrees of counter-ion binding by micelles are calculated by the Evans’ method, and then values of the Gibbs free energy of micelle formation are found. Magnitudes of counter-ion-binding degrees and values of the Gibbs free energy are higher than those are for surfactants with singly charged anions of the same hydrocarbon-radical length.
