Provided herein are methods of forming an aqueous dispersion suitable for use in a chemically produced toner that include a) dissolving a polyester resin in a volatile organic solvent to form a solution of the polyester in the volatile organic solvent; b) adding a neutralizing agent comprising at least one of an alkali metal hydroxide, an ammonium hydroxide and a tertiary amine, and water to the solution of the polyester in the volatile organic solvent to form a first aqueous dispersion; and c) heating the dispersion to remove solvent to provide a second aqueous dispersion. Also provided are aqueous dispersions formed by methods according to embodiments of the invention and toners resin compositions including an aqueous dispersion according to an embodiment of the invention.
