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:
70-92.5% by weight of a bleach material comprising at least 60% PAP by weight;
5-20% by weight of a binder comprising isomalt; and
2.5-10% by weight of a disintegrant comprising a soy saccharide; and

a coating;
wherein the coating comprises mannitol, and
wherein the coating comprises between 10 and 20% by weight of the particle core.

2. The dyed particle according to claim 1 , wherein dye is located in the coating.

3. The dyed particle according to claim 1 , wherein dye is located on the coating.

4. The dyed particle according to claim 1 , wherein the coating comprises two or more layers.

5. The dyed particle according to claim 4 , wherein dye is located in the outer layer of the coating.

6. The dyed particle according to claim 4 , wherein dye is located on the outer layer of the coating.

7. The dyed particle according to claim 1 , wherein the total weight of coating is between 2.5% and 60% by weight of the particle.

8. A detergent composition comprising at least one dyed particle of claim 1 .

9. A method comprising placing the detergent composition of claim 8 in an automatic dishwashing machine and washing dish wares.

10. The detergent composition according to claim 8 , wherein the detergent composition comprises one of a gel and a liquid.

11. The detergent composition according to claim 8 , wherein the detergent composition comprises a compressed tablet.

12. The detergent composition according to claim 8 , wherein the detergent composition comprises one or both of a powder and granules.

13. A contained detergent composition comprising:
the detergent composition of claim 8 ; and

a container within which the detergent composition is contained.

14. The contained detergent composition according to claim 13 , wherein the container is a flexible polyvinylalcohol (PVOH) film.

15. The detergent composition according to claim 13 , wherein the container is a rigid polyvinylalcohol (PVOH) casing.
