Abstract (en)
[origin: WO03052042A2] A layered liquid detergent composition in a water-soluble single use package, wherein the package is in the shape of a polyhedron, preferably a tetrahedron. The composition comprises at least two layers, hydrophilic and hydrophobic, with the hydrophobic layer preferably on top. The hydrophobic layer preferably comprises a sensitive benefit ingredient (e.g., enzyme), which is contained predominantly in the hydrophobic layer. By virtue of the shape of the package, the interface between the top layer and the next lower layer is minimized, which in turn leads to a reduced interaction between the two layers, resulting in the increased stability of the ingredient in the top layer.
