✦ Synopsis

The effect of additives on micellar aggregation is treated using the same framework developed for macromolecular binding. This procedure, hinging on the pseudo-phase transition model, allows us to evaluate the binding constant of any added substance to a micellar aggregate as well as the number of particles bound per amphiphilic unit. The analysis of published literature data confirms that the model provides a general description of micellar aggregation in the presence of added ingredients, regardless of their ionic or non-ionic nature. Original data from our laboratory are well described by the suggested macromolecular binding approach. The dependence of experimental trends on micellization modifiers is also briefly discussed.
