Outline of Final Research Achievements |
Active interfacial modifier (AIM) is a general concept regarding amphiphilic materials. In emulsion systems, AIM is intrinsically insoluble in both continuous and dispersed liquid phases, but possesses moieties that are attracted to each of these immiscible liquid phases. Hence, AIM practically stays just at the interface and stabilizes the emulsion systems without a loss of materials. In this research project, polyion complex was employed as AIM and oil-in-water type emulsions were prepared on the basis of the AIM concept. The experimental results obtained in this project indicated that the AIM-stabilized emulsions experienced destabilization through creaming or flocculation rather than coalescence because of the presence of the independent AIM phase or layer around emulsion droplets.
