Critical Packing Parameter Solution

STEP 0: Pre-Calculation Summary
Formula Used
critical_packing_parameter = Surfactant Tail Volume/Optimal Area*Tail Length
CPP = v/ao*l
This formula uses 3 Variables
Variables Used
Surfactant Tail Volume - Surfactant tail Volume is defined as the volume occupied by the tail of the surfactant. (Measured in Cubic Centimeter)
Optimal Area - Optimal Area is defined as equilibrium area per molecule (head group) at the aggregate interface. (Measured in Square Centimeter)
Tail Length - Tail length is defined as the measurement of the extent of something along its greatest dimension. (Measured in Centimeter)
STEP 1: Convert Input(s) to Base Unit
Surfactant Tail Volume: 50 Cubic Centimeter --> 5E-05 Cubic Meter (Check conversion here)
Optimal Area: 50 Square Centimeter --> 0.005 Square Meter (Check conversion here)
Tail Length: 50 Centimeter --> 0.5 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
CPP = v/ao*l --> 5E-05/0.005*0.5
Evaluating ... ...
CPP = 0.005

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.

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.

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 -> 0.005 = 5E-05/0.005*0.5.

FAQ

What is 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 and is represented as CPP = v/ao*l or critical_packing_parameter = Surfactant Tail Volume/Optimal Area*Tail Length. Surfactant tail Volume is defined as the volume occupied by the tail of the surfactant, Optimal Area is defined as equilibrium area per molecule (head group) at the aggregate interface & Tail length is defined as the measurement of the extent of something along its greatest dimension.
How to calculate 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 is calculated using critical_packing_parameter = Surfactant Tail Volume/Optimal Area*Tail Length. To calculate Critical Packing Parameter, you need Surfactant Tail Volume (v), Optimal Area (ao) & Tail Length (l). With our tool, you need to enter the respective value for Surfactant Tail Volume, Optimal Area & Tail Length and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Critical Packing Parameter?
In this formula, Critical Packing Parameter uses Surfactant Tail Volume, Optimal Area & Tail Length. We can use 3 other way(s) to calculate the same, which is/are as follows -
  • critical_packing_parameter = Surfactant Tail Volume/Optimal Area*Tail Length
  • surfactant_tail_volume = Critical Packing Parameter*Optimal Area*Tail Length
  • tail_length = Surfactant Tail Volume/(Critical Packing Parameter*Optimal Area)
