Phenomenological Model for Compositional Ripening

In the absence of coalescence, the global molecular flow 7 of a species across the oil globules is entropic in origin and is described by Eick s law  

Combining Eq. (6.8) and the conservation condition, the following expression for the relative percentage of release is derived  

Here Cf is the initial concentration of the encapsulated species in the internal droplets. The model predicts an exponential leakage as a function of time. If S is assumed to be equal to the total globule surface area, P can be numerically deduced from the initial slope po of the experimental curves
