Abstract
Disclosed herein are methods for producing liquid detergent products using a vessel comprising an inlet, an outlet, an agitation device, and an additive mixing zone disposed between the inlet and the outlet. The method comprises introducing an unstructured liquid detergent precursor into the inlet of the vessel; mixing an additive and the unstructured liquid detergent precursor in an additive mixing zone to form a combined additive detergent; adding a structurant to the combined additive detergent downstream of the additive mixing zone to form a liquid detergent product. The liquid detergent products may be used in a water-soluble pouch, for e.g., a multi-compartment water-soluble pouch.
Claims24
A method for producing a liquid detergent product using a vessel comprising an inlet, an outlet, an agitation device, and a microcapsule mixing zone disposed between the inlet and the outlet, the method comprising:
- a) introducing an unstructured liquid detergent precursor into the inlet of the vessel, said unstructured liquid detergent precursor comprising from about 10% to 90%, by weight of the precursor, of a surfactant, and from about 0% to about 15%, by weight of the precursor, of water;
- b) mixing an aqueous slurry comprising perfume microcapsules and the unstructured liquid detergent precursor in the microcapsule mixing zone to form a combined microcapsule detergent;
- c) adding a structurant to the combined microcapsule detergent downstream of the microcapsule mixing zone to form a liquid detergent product.
A method for forming a liquid detergent product using a vessel comprising an inlet, an outlet, and an opacifier mixing zone disposed between the inlet and the outlet and comprising an agitation device, the method comprising:
- a. introducing an unstructured liquid detergent precursor into the inlet of the vessel, said precursor comprising from about 10% to 90%, by weight of the precursor, of a surfactant, and from about 0% to about 15%, by weight of the precursor, of water;
- b. adding an opacifier to the unstructured liquid detergent precursor upstream of the opacifier mixing zone;
- c. mixing the opacifier and the unstructured liquid detergent precursor in the opacifier mixing zone to form an opaque detergent;
- and
- d. adding a structurant to the opaque detergent downstream of the opacifier mixing zone to form the liquid detergent product.
