Combination of liquid colorant technology and developer housed in a cartridge and paired with the colorsonic device with optimized number of static mixers and flow-path design, that dispenses colorant mixture with an ideal, non-dripping aspect

A formulation delivery system, comprising:

• a first formulation source storing a first liquid formulation, wherein the first liquid formulation comprises:
• a surfactant system,
• at least one alkaline component,
• at least one chelating agent, and
• a solvent system,
• a second formulation source storing a second liquid formulation, wherein the second liquid formulation comprises hydrogen peroxide;
• a formulation dispensing assembly configured to fluidically couple with the first formulation source and the second formulation source, the formulation dispensing assembly comprising:
• a first fluid conduit and a second fluid conduit respectively connected with the first formulation source and the second formulation source;
• a pump fluidically connected to the first fluid conduit and second fluid conduit;
• a mixing chamber connected with the first fluid conduit and the second fluid conduit, wherein the mixing chamber mixes the first formulation with the second formulation into a mixed formulation having a 1:1 mixture ratio of the first formulation and the second formulation with a 20% mixture ratio tolerance;
• and
• a nozzle assembly in fluid connection with the mixing chamber.
