Claims12
A stable aqueous/aqueous emulsion system which is prepared with a hydrophilic polymer.
The method of preparing for preparing a stable aqueous/aqueous emulsion comprising steps of:
- a) selecting appropriate polymeric materials for dispersed phase and continuous phase which are immiscible, biocompatible and have biased partition to the active ingredients to be encapsulated;
- b) selecting appropriate surface modifiers which are charged, non-toxic, and possessing a moderate interfacial tension between the above two phases;
- c) developing phase diagram for the above;
- and
- d) dispersing the dispersed phase into the continuous phase under an appropriate shear stress.
