Abstract

In this report, we controlled quantity of the hydrophilic surfactant maximally by employing minute O/W type emulsion which used high pressure homogenizer for primary emulsification and showed that this method improved stability of the O/W/O type emulsion. We also showed that a polymer surfactant polyoxyethylene (30) dipolyhydroxystearate (PEDS) helped preparing a new (O1+O2)/W/O3 type emulsion. For the preparation of the new emulsion, O/W/O type emulsion and (O1+O2)/W type emulsion, where O1 and O2 has different compositions and particle diameters, were combined. A possibility of the control release of the included oil-soluble ingredients in the new emulsion was discussed and effective utilization of surfactants in the O/W/O type emulsion was explained.
