Abstract

A water-soluble pouch suitable for use in machine dishwashing and which comprises a plurality of compartments in generally superposed or superposable relationship, each containing one or more detergent active or auxiliary components, and wherein the pouch has a volume of from about 5 to about 70 ml and a longitudinal/transverse aspect ratio in the range from about 2:1 to about 1:8, preferably from about 1:1 to about 1:4. The water-soluble pouch allows for optimum delivery of dishwashing detergent. A process for the manufacture of multi-compartment pouches and a pack to contain the pouches are also disclosed.

First claim

The invention claimed is:

1. A water-soluble pouch comprising a plurality of compartments in generally superposed relationship, wherein the plurality of compartments comprises a first compartment and a second compartment, wherein the first compartment comprises a liquid composition, wherein the liquid composition comprises one or more detergent active or auxiliary components and an organic solvent system.

2. A water-soluble pouch according to claim 1 , wherein the second compartment of the plurality of compartments comprises one or more detergent active or auxiliary components.

3. A water-soluble pouch according to claim 1 , wherein the second compartment comprises a liquid composition.

4. A water-soluble pouch according to claim 3 , wherein the second compartment comprises an organic solvent system.

5. A water-soluble pouch according to claim 3 , wherein the second compartment comprises a solid composition.

6. A water-soluble pouch according to claim 1 , wherein the first compartment and the second compartment are arranged in a side-by-side relationship.

7. A water-soluble pouch according to claim 6 , wherein the first compartment and the second compartment are arranged in a generally superposable relationship.

8. A water-soluble pouch according to claim 1 , wherein the pouch has a volume of from about 5 to about 70 ml.

9. A water-soluble pouch according to claim 1 , wherein one or more of said plurality of compartments comprises a detergency enzyme.

10. A water-soluble pouch according to claim 1 , wherein said organic solvent system comprises an organic solvent selected from the group consisting of organoamine solvents, alcoholic solvents, glycols, glycol derivatives, and mixtures thereof;
wherein said the organoamine solvents are selected from the group consisting of alkanolamines, alkylamines, alkyleneamines, and mixtures thereof;
wherein the alcoholic solvents are selected from the group consisting of aromatic alcohols, aliphatic alcohols, cycloaliphatic alcohols, and mixtures thereof; and
wherein the glycols and glycol derivatives are selected from the group consisting of C 2 -C 3 (poly)alkylene glycols, glycol ethers, glycol esters, and mixtures thereof.

11. A water-soluble pouch according to claim 1 , wherein said one or more liquid detergent active or auxiliary components in said first compartment comprises a surfactant.

12. A pouch according to claim 11 , wherein said surfactant comprises anionic surfactant, wherein said anionic surfactant comprises alkyl sulfates, alkyl ether sulfates, alkyl benzene sulfates, or mixtures thereof.

13. A water-soluble pouch according to claim 1 , wherein said pouch comprises at least three compartments.

14. A water-soluble pouch according to claim 1 , wherein the pouch is made of a pouch material formed into a film, wherein the pouch material comprises polyvinyl alcohol polymer, copolymers, or derivatives thereof.

15. A water-soluble pouch according to claim 14 , wherein the liquid composition and the film both comprise a plasticizer.
