Patent ID: 7129201

Claim:
A stable, aqueous-aqueous emulsion comprising (1) a dispersed aqueous phase comprising a molecule or combination of molecules meeting the following criteria: (a) water solubility of greater than 5%; and (b) MW>about 200 and <about 200,000; and (2) a continuous phase comprising surfactant or surfactant system having micelles in rod-like shape, wherein rod-like is defined by a surfactant parameter of surfactant or surfactants forming the micelle, Ns, of about ⅓−½, where Ns is defined by the equation: Ns=V/Ia o where V=volume of the hydrophobic portion of the surfactant volume; I=the length of the hydrocarbon claims of the surfactant; and a o =effective area for head group; wherein the molecules in the dispersed phase are selected from the group consisting of maltodextrins having MW of about 500 to 5000; PVP having MW of about 7000; dextran having MW of about 70,000; PEG having MW of about 1000, and mixtures thereof.
