Abstract
The present invention discloses a three-phase heavy-duty laundry detergent wipe, comprising a substrate 1 which is solid at ambient temperature as a third phase and a dispersion applied to the substrate and consisting of a liquid washing detergent 5 as a first phase and a water insoluble functional additive 2 as a second phase; and a method for manufacturing same. In particular, the second phase, i.e., the additive 2, of the dispersion can be a zeolite. The substrate 1 can consist of fatty alcohols, viscose, polyethylene, polypropylene or polyester. Furthermore, the present invention discloses a homogeneous three-phase laundry detergent wipe and a method for manufacturing same, wherein the substrate is moistened with the dispersion via direct contact with a first moistening rod 3 which rests on one side of the substrate to be moistened and a second counter moistening rod 4 which rests on the opposing side of the substrate to be moistened such that the washing active substances and solid components of the dispersion 2, resp., are distributed homogeneously across the substrate after moistening.
