PROCESS FOR MAKING POLYSILOXANE EMULSIONS ABSTRACT Disclosed is a method for producing emulsions from high viscosity polysiloxanes, bi-modal polysiloxane fluids, functional polysiloxanes and mixtures thereof. The method comprises forming a thick phase emulsion by blending a polysiloxane, at least one primary surfactant and water. To the blend, at least one secondary surfactant is added. The mixture is then mixed using shear for a sufficient period of time until an average particle size of less than 350 nanometers is achieved. The thick phase emulsion is then diluted with additional water to the desired silicone content to form the final emulsion.
