Abstract: Disclosed herein are formulations and processes for the preparation of pigment and wax dual dispersions by (1) providing a solution comprising a water and at least one surfactant in a dispersion apparatus comprising a container, a rotor-stator homogenizer, and a piston homogenizer coupled via a recirculation device; (2) adding at least one pigment to the solution; (3) forming a pigment dispersion by flowing the at least one pigment and the solution to the rotor-stator homogenizer via the recirculation device; (4) adding at least one wax to the pigment dispersion; and (5) flowing the at least one wax and pigment dispersion to the piston homogenizer via the recirculation device until a pigment and wax dual dispersion is formed. Also disclosed herein are pigment and wax dual dispersions, as well as a dispersion apparatus for preparing pigment and wax dual dispersions. In certain embodiments, a dispersion apparatus for preparing a pigment and wax dual dispersion may comprise a container, a rotor-stator homogenizer, a piston homogenizer, and a recirculation device coupled to the container and the homogenizers that allows a dispersion to flow between the container and the homogenizers.
