Only 10 seconds : Hydrocarbons and water do not mix under standard conditions, but they do mix freely at high temperature and high pressure near the gas/liquid critical point of water ( T c =374 °C, P c =22.1 MPa). Quenching of homogeneous solutions of dodecane and water at such extreme conditions in the presence of a surfactant results in bottom‐up formation of nanosized oil droplets in water in only 10 seconds.
