摘要：Methods for preparing all-aqueous emulsions, including stable emulsions oremulsions having high viscosity and/or ultra-low interfacial tension are described. Themethod includes mixing, combining, or contacting a first electrically charged phasecontaining a first solute (e.g., dispersed phase) with at least a second phase containing asecond solute (e.g., continuous phase). The solutes are incompatible with each other. Theelectrostatic forces between the two phases induce the formation of droplets of adispersed phase in a continuous phase. The dispersed and continuous phases containoppositely charged molecules, such as surfactants or other macromolecules and colloidswhich stabilize the drops of the dispersed phase. Complex coacervation of the oppositelycharged molecules or colloids at the interface of the two aqueous phases results information of a membrane or barrier which prevents coalescence or aggregation of thedroplets. The membrane also prevents leakage of any encapsulated agents from thedroplets.
