A process for making a resin emulsion suitable for use in forming toner particles is provided. In embodiments, a suitable process includes melt mixing a resin in the absence of an organic solvent, optionally adding a surfactant to the resin, adding to the resin a basic agent and water, and subjecting the resin, basic agent and water to acoustic mixing at a suitable frequency to form an emulsion of resin particles. In embodiments, the resin emulsion thus produced may be utilized to form a toner.
