Association Colloid
a binary or multicomponent system whose structure and properties are between those of liquid solutions and sols. Association colloids are microheterogeneous systems in which the particles of the colloidal dispersed phase (micelles) are formed by the agglomeration of molecules or ions of the substance dissolved in the dispersion medium. The micelles, or associates, are in thermodynamic equilibrium with the surrounding solution; therefore, a change in the external conditions, the composition of the dissolving medium, or the concentration of the dissolved (dispersed) substance causes redistribution of the substance between the micelles and the solution.
