Abstract

A composition in a water-soluble pouch, the pouch comprises at least two compartments, and each compartment contains a different component of the composition, wherein a first compartment contains a first component and the first component comprises a liquid matrix and a source of peracid.

Claims (30)

1. A multiple compartment water soluble pouch containing a detergent composition, said pouch comprising at least two compartments comprising:

a first compartment containing: a first component of said detergent composition, said first component comprising a mineral oil liquid matrix and a source of peracid; and

a second compartment joined to said first compartment, said second compartment containing a second component of said detergent composition,

wherein the compartments of the pouch containing said components are of a different color from each other.

2. The multiple compartment pouch of claim 1 wherein the first compartment is green or blue and the second compartment is white.

3. The multiple compartment pouch of claim 1 wherein the first compartment is translucent, transparent, or semi-transparent and the second compartment is opaque or semi-opaque.

4. The multiple compartment pouch of claim 2 wherein the first compartment is translucent, transparent, or semi-transparent and the second compartment is opaque or semi-opaque.

5. The multiple compartment pouch of claim 1 wherein said second component comprises a solid matrix.

6. The multiple compartment pouch of claim 2 wherein said second component comprises a solid matrix.

7. The multiple compartment pouch of claim 3 wherein said second component comprises a solid matrix.

8. The multiple compartment pouch of claim 1 wherein said pouch comprises at least three pieces of pouch material comprising a first piece of pouch material, a second piece of pouch material, and a third piece of pouch material, wherein said second piece of pouch material is positioned so that it at least partially overlaps the first piece of pouch material and said first piece of pouch material and said second piece of pouch material are sealed together, and said third piece of pouch material creates a barrier layer between said first and second pieces of pouch material that divides the pouch into said at least two compartments.

9. The multiple compartment pouch of claim 1 wherein the first and second compartments are of different sizes, having different internal volumes.

10. The multiple compartment pouch of claim 2 wherein the first and second compartments are of different sizes, having different internal volumes.

11. The multiple compartment pouch of claim 3 wherein the first and second compartments are of different sizes, having different internal volumes.

12. The multiple compartment pouch of claim 5 wherein the first and second compartments are of different sizes, having different internal volumes.

13. The multiple compartment pouch of claim 8 wherein the first and second compartments are of different sizes, having different internal volumes.

14. The multiple compartment pouch of claim 5 wherein the first compartment also contains an air bubble.

15. A multiple compartment water soluble pouch containing a detergent composition, said pouch comprising at least two compartments comprising:

a first compartment containing a first component of said detergent composition, which first component comprises a mineral oil liquid matrix and a source of peracid, wherein said first compartment also contains an air bubble having a volume of no more than 50% of the volume space of said first compartment; and

a second compartment joined to said first compartment, said second compartment containing a second component of said detergent composition.

16. The multiple compartment pouch of claim 15 wherein said liquid matrix has a viscosity of at least 300 mPas.

17. The multiple compartment pouch of claim 15 wherein said pouch comprises at least three pieces of pouch material comprising a first piece of pouch material, a second piece of pouch material, and a third piece of pouch material, wherein said second piece of pouch material is positioned so that it at least partially overlaps the first piece of pouch material and said first piece of pouch material and said second piece of pouch material are sealed together, and said third piece of pouch material creates a barrier layer between said first and second pieces of pouch material that divides the pouch into said at least two compartments.

18. The multiple compartment pouch of claim 15 wherein said liquid matrix comprises dispersed and/or suspended solid particles.

19. The multiple compartment pouch of claim 15 wherein the second component comprises a solid matrix.

20. The multiple compartment pouch of claim 19 wherein said solid matrix comprises peracid incompatible ingredients.

21. The multiple compartment pouch of claim 20 wherein said peracid incompatible ingredients are selected from perfumes, enzymes, chelants and combinations thereof.

22. A multiple compartment water soluble pouch containing a detergent composition, said pouch comprising at least two compartments comprising:

a first compartment containing a first component of said detergent composition, which first component comprises a mineral oil liquid matrix and a source of peracid, wherein said first compartment also contains an air bubble having a volume of no more than 50% of the volume space of said first compartment; and

a second compartment joined to said first compartment, said second compartment containing a second component of said detergent composition,

wherein said pouch is configured to at least partially dissolve in such a manner that it dispenses said first component before said second component.
