What is the Critical Packing Parameter?

The Critical packing parameter (CPP) is a theoretical framework for determining the type of aggregation formed by surfactants (i.e. as spherical or cylindrical micelles, or vesicles, or flexible or fixed bilayers.)

What is the use of Critical Packing Parameter?

The concept of the critical packing parameter is a simplification, for instance, the parameter a0 is not a geometrical area but an equilibrium parameter derived from thermodynamic considerations, meaning that predicting the aggregate structure becomes very complicated for solutions having many different parameters that could vary simultaneously, e.g. salt concentration, temperature, pH etc.
