Abstract:
1. 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, where the agitation device is in the microcapsule mixing zone, 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 water, which is present in an amount of up to about 15% by weight of the precursor; b) mixing with the agitation device an aqueous slurry comprising perfume microcapsules and the unstructured liquid detergent precursor in the microcapsule mixing zone to form a combined microcapsule detergent, wherein the aqueous slurry has a viscosity of at least about 300 mPas at 25° C., and wherein the agitation device is a static mixer; c) adding a structurant comprising hydrogenated castor oil to the combined microcapsule detergent downstream of the microcapsule mixing zone to form a liquid detergent product; and wherein the liquid detergent product has an average microcapsule aggregate particle size of less than 75 μm.
