Abstract

Detergent compositions comprising a water-soluble film and a shading dye. At least about 10% of the shading dye is incorporated into the water-soluble film. Methods of making such detergent compositions.

First claim

What is claimed is:

1. A unit dose article comprising:
a. a first composition
b. at least two compartments comprising water-soluble films, wherein one compartment encapsulates the first composition; and
c. a shading dye
wherein said first composition is selected from the group consisting of a liquid detergent, a granular detergent, or a tablet detergent,
wherein the shading dye has the following structure:
Dye-(G)a-NR 1 R 2 ,

wherein the -(G)a-NR 1 R 2 group is attached to an aromatic ring of the dye, G is independently —SO 2 — or —C(O)—, the index a is an integer with a value of 0 or 1, and R 1 and R 2 are independently selected from the group consisting of H, a polyoxyalkylene chain, C 1-8 alkyl, C 6-10 aryl, C 7-16 alkaryl, polyoxyalkylene chain substituted C 1-8 alkyl, polyoxyalkylene chain substituted C 6-10 aryl, polyoxyalkylene chain substituted C 7-16 alkaryl and mixtures thereof; said polyoxyalkylene chains independently having from about 2 to about 100 repeating units, wherein the water-soluble films comprise a first film, a second film and a common wall, wherein the common wall is shared by the at least two compartments, wherein substantially all of the shading dye is incorporated into the common wall of the unit dose article and the first film and second film are free of the shading dye, wherein the shading dye is added to the common wall prior to casting or extrusion of the common wall, and wherein the shading dye forms an integral part of the common wall.

2. A unit dose article according to claim 1 , wherein the shading dye is selected from the group consisting of acridines, anthraquinones, azines, azos, benzodifuranes, benzodifuranones, carotenoids, coumarins, cyanines, diazahemicyanines, diphenylmethanes, formazans, hemicyanines, indigoids, naphthalimides, naphthoquinones, nitros, nitrosos, oxazines, phthalocyanines, pyrazoles, stilbenes, styryls, triarylmethanes, triphenylmethanes, xanthenes and mixtures thereof.

3. A unit dose article according to claim 1 , wherein the shading dye is selected from the group consisting of an anthraquinone dye, an azine dye, an azo dye, a polymeric anthraquinone dye, a polymeric azine dye, a polymeric azo dye, and mixtures thereof.

4. A unit dose article according to claim 1 , wherein the shading dye is a polymeric dye and at least one of R 1 and R 2 comprises a polyoxyalkylene chain.

5. A unit dose article according to claim 4 , wherein the polyoxyalkylene chain comprises from about 2 to about 50 repeating units, wherein the repeating units are essentially ethylene oxide.

6. A unit dose article according to claim 1 , wherein the first composition is a liquid detergent.

7. A unit dose article according to claim 1 , wherein the first composition comprises less than 50% water.

8. A unit dose article according to claim 1 , wherein said first composition comprises an adjunct selected from the group consisting of surfactants, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzymes, enzyme stabilizers, catalytic materials, bleach activators, polymeric dispersing agents, clay soil removal agents, anti-redeposition agents, brighteners, suds suppressors, dyes, perfume, perfume delivery systems, structure elasticizing agents, fabric softeners, carriers, hydrotropes, processing aids, pigments and mixtures thereof.
