Possible theoretical treatments for transfer processes through membranes.
The transfer process of salicylic acid through a cellophane membrane is studied. The active component is formulated as a semisolid emulsion (O/W) for external local application. Different theoretical mathematical models are applicable to the experimental data obtained in order to find the mathematical expressions which define the transfer kinetics. Later on, comparative studies of these mathematical models are carried out in order to choose the one which better defines the whole transfer process.
