Abstract

The invention relates to dyed particles of a bleach material that comprise a coating. The invention also relates to the use of the dyed particles in detergent compositions.

First claim

The invention claimed is:

1. A dyed particle comprising:
a core comprising bleach material, a non-reducing sugar binder, and a disintegrant; and
a coating comprising mannitol,
wherein the bleach material comprises at least one inorganic peroxide or organic peracid, and
wherein the weight ratio of bleach material:binder:disintegrant is between 60:30:10 and 92.5:5:2.5.

2. A detergent composition comprising:
a builder;
a nonionic surfactant; and
at least one dyed particle, the at least one dyed particle comprising:
a core comprising bleach material a non-reducing sugar binder, and a disintegrant; and
a coating comprising mannitol,

wherein the bleach material comprises at least one inorganic peroxide or organic peracid,
wherein the detergent composition is formulated for use in an automatic dishwashing machine, and
wherein the weight ratio of bleach material:binder:disintegrant is between 60:30:10 and 92.5:5:2.5.

3. The detergent composition according to claim 2 , wherein the detergent composition comprises one of a gel or a liquid.

4. The detergent composition according to claim 2 , wherein the detergent composition comprises a compressed tablet.

5. The detergent composition according to claim 2 , wherein the detergent composition comprises one or both of a powder and granules.

6. The detergent composition of claim 2 , wherein the bleach material is an organic peracid.

7. The detergent composition of claim 2 , wherein the bleach material is 6-phthalimido-peroxy-hexanoic acid (PAP).

8. The detergent composition according to claim 2 , wherein the binder is isomalt (6-O-α-D-Glucopyranosyl-D-sorbitol (1,6-GPS)+1-O-α-D-Glucopyranosyl-D-mannitol dehydrate (1,1-GPM).

9. The detergent composition according to claim 2 , wherein the disintegrant comprises a saccharide.

10. The detergent composition according to claim 2 , wherein the disintegrant comprises a soy saccharide.

11. The detergent composition of claim 2 , wherein dye is located in the coating.

12. The detergent composition of claim 2 , wherein dye is located on the coating.

13. The detergent composition of claim 2 , wherein the coating comprises two or more layers.

14. The detergent composition according to claim 13 , wherein dye is located in the outer layer of the coating.

15. The detergent composition according to claim 13 , wherein dye is located on the outer layer of the coating.

16. The detergent composition of claim 2 , wherein the total weight of the coating is between 2.5% and 60% by weight of each particle.

17. The detergent composition of claim 2 further comprising:
a container within which the detergent composition is contained.

18. The detergent composition according to claim 17 , wherein the container comprises a flexible polyvinylalcohol (PVOH) film.

19. The detergent composition according to claim 17 , wherein the container comprises a rigid polyvinylalcohol (PVOH) casing.
