A method of and an apparatus for producing ultra-thin emulsions and dispersions is disclosed. The method includes the steps of passing a hydrodynamic liquid flow containing dispersed components through a flow-through channel having at least one nozzle and a buffer channel and directing a primary liquid jet from the nozzle into the buffer channel, thereby creating a secondary liquid jet in the buffer channel directed toward the nozzle. The primary liquid jet and the secondary liquid jet create a high intensity vortex contact layer that creates collapsing cavitation caverns and cavitation bubbles in the high intensity vortex contact layer. Ultra-thin emulsions and dispersions are formed under the influence of the collapsing cavitation caverns and cavitation bubbles. The apparatus includes a flow-through channel having an inlet and an outlet and a nozzle located inside the flow-through channel between the inlet and the outlet and having an orifice. A primary liquid jet is created as the hydrodynamic liquid flow passes through the orifice of the nozzle. The apparatus also includes a buffer channel located in a wall of the flow-through channel opposite of the orifice of the nozzle such that the primary liquid jet is directed into the buffer channel.
