A finely monodispersed oil-in-water (O/W)emulsion was obtainedunder high temperature and pressureconditions(240 °C and 10 MPa). A coarse emulsion stabilized by Tween 20 was prepared in advance from the decane/water system to be treated under the subcritical conditions. The treated coarse emulsion was thereafter mixed with the aqueous solution including surfactants to improve the monodispersity of the oil droplets. The subcritical condition could supply sufficient energy to produce finely dispersed oil droplets (~233 nm in diameter).
