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.
How to Calculate Critical Packing Parameter?
Critical Packing Parameter calculator uses Critical Packing Parameter = Surfactant Tail Volume/(Optimal Area*Tail Length) to calculate the Critical Packing Parameter, The critical packing parameter (CPP) is a measure of the ratio between the portion hydrophilic head and the portion hydrophobic tail of the surfactant. Critical Packing Parameter is denoted by CPP symbol.
How to calculate Critical Packing Parameter using this online calculator? To use this online calculator for Critical Packing Parameter, enter Surfactant Tail Volume (v), Optimal Area (ao) & Tail Length (l) and hit the calculate button. Here is how the Critical Packing Parameter calculation can be explained with given input values -> 0.018854 = 5E-05/(0.0051*0.52).
