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 are factors affecting Optimal Area?

One can change the optimal head group area by
(a) decreasing or increasing the electrolyte concentration in the case of ionic surfactants.
(b) changing the pH to effect an increase or decrease in the dissociation of the head group.
Similarly, in the case of nonionic surfactants (such as polyoxyethylene surfactants), changing the degree of ethoxylation of the head group, or decreasing the temperature (which increases the extent of hydration), will increase the optimal head group area.
