A method employing a ultrasonicator apparatus to emulsify a pressurized multi-component liquid. The apparatus includes a die housing comprising a chamber adapted to receive a pressurized multi-component liquid, an inlet adapted to supply the chamber with the pressurized multi-component liquid, an exit orifice defined by the walls of a die tip, and a means for applying ultrasonic energy to a portion of the pressurized liquid. The method for emulsifying a pressurized multi-component liquid comprising supplying a pressurized multi-component liquid to the apparatus, applying ultrasonic energy to the pressurized liquid but not the die tip while the exit orifice receives pressurized liquid from the chamber, and passing the pressurized liquid out of the exit orifice in the die tip so that the multi-component liquid is emulsified, wherein the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip.
