Generally, multiple emulsion in which the dispersed particles are themselves emulsions, has been prepared by two-step emulsification. But because of complexity of this method, the simplified process by one-step emulsification was introduced in this study. To prepare O/W/O multiple emulsion, two nonionic surfactants and two polymers were used. This multiple emulsion has three types of emulsion droplets. The stability of multiple emulsion prepared under the condition of 1.4 wt% HPC, 18 wt% PEG, 5 wt% Tween20, and 3 wt% Span80, was investigated by optical microscope. |
