A method and apparatus for making silicone-in-water emulsions comprising high viscosity silicone polymers is provided. In various aspects, polyorganosiloxanes are polymerized into high viscosity silicone polymers then emulsified in a continuous process, wherein the process is carried out using a single apparatus. In some aspects, the provided apparatus is an extruder for polymerizing polyorganosiloxanes into high viscosity silicone polymers and then emulsifying such polymers.
