A process for improving aesthetics of a liquid dishwashing detergent product is disclosed. The process includes the steps of providing a liquid dishwashing detergent composition and adding solid particles to the liquid dishwashing detergent composition. The particles are coated with a polymeric coating. The coating is prepared from materials which are insoluble in the liquid dishwashing detergent composition but soluble in dishwashing wash solution.

1. A process of improving aesthetics of a liquid dishwashing detergent product, comprising the steps of:a) providing a liquid dishwashing detergent composition; andb) adding solid particles to the liquid dishwashing detergent composition, wherein the particles comprise a hydrated polymeric coating formed from a sprayable aqueous solution comprising from about 1% to about 30% by weight of a polymeric material, wherein the polymeric coating is insoluble in the liquid dishwashing detergent composition but soluble in dishwashing solution and wherein the polymeric coating and the liquid automatic dishwashing composition comprise observed color with or without whitening selected from the group consisting of blue, blue-green, green, yellow, white, and combinations thereof. 2. The process according to claim 1, wherein the polymeric coating comprises about 5% by weight of the particle. 3. The process according to claim 1, wherein the polymeric material comprises alkyl cellulose ether, polyvinyl alcohol, or mixtures thereof. 4. The process according to claim 3, wherein the polymeric material comprises methyl cellulose. 5. The process according to claim 4, wherein the methyl cellulose has a molecular weight in a range of from about 5,000 to about 100,000. 6. A process of improving aesthetics of a liquid dishwashing detergent product, comprising the steps of:a) providing a liquid dishwashing detergent composition; andb) adding solid particles to the liquid dishwashing detergent composition, wherein the particles are coated with a polymeric coating which is insoluble in the liquid dishwashing detergent composition but soluble in dishwashing solution, wherein the polymeric coating comprises alginate. 7. The process according to claim 1, wherein the particles are present in the liquid dishwashing detergent composition in an amount in a range of from about 0.1% to about 5.0% by weight of the liquid dishwashing detergent product. 8. The process according to claim 7, wherein the particles are present in the liquid dishwashing detergent composition in an amount in a range of from about 0.2% to about 1.0% by weight of the liquid dishwashing detergent product. 9. The process according to claim 1, wherein the polymeric material comprises from about 3% to about 20% by weight of the sprayable aqueous solution. 10. The process according to claim 1, wherein the polymeric material comprises from about 3% to about 10% by weight of the sprayable aqueous solution. 11. The process according to claim 1, wherein the sprayable aqueous solution is at a temperature from about 30° C. to about 40° C. 12. A liquid dishwashing detergent product having enhanced aesthetics, comprising:a) a liquid dishwashing detergent composition; andb) solid particles, wherein the particles comprise a hydrated polymeric coating formed from a sprayable aqueous solution comprising from about 1% to about 30% by weight of a polymeric material, wherein the material is selected from the group consisting of alkyl cellulose ethers, polyvinyl alcohol, alginate and mixtures thereof, and wherein the particles are adapted to remain undissolved in the liquid dishwashing detergent composition until the composition is adapted for manual or automatic dishwashing and wherein the polymeric coating and the liquid automatic dishwashing composition comprise observed color with or without whitening selected from the group consisting of blue, blue-green, green, yellow, white, and combinations thereof. 13. The liquid dishwashing detergent product according to claim 12, wherein the polymeric coating comprises about 5% by weight of the particle. 14. The liquid dishwashing detergent product according to claim 12, wherein the polymeric material comprises methyl cellulose having a molecular weight in a range of from about 5,000 to about 100,000. 15. The liquid dishwashing detergent product according to claim 12, further comprising one or more of an enzyme, a nonionic low foaming surfactant, a dispersa nt polymer, an alkalinity forming agent, a phosphate builder, a bleaching species, and a pH adjusting component. 16. The liquid dishwashing detergent product according to claim 12, wherein the detergent product delivers a wash solution pH in a range of from about 8.0 to about 12.0. 17. The liquid dishwashing detergent product according to claim 12, further comprising a dispersant polymer selected from the group consisting of polyacrylates and polyacrylate copolymers in an amount of from about 0.5% to about 20% by weight of the detergent product. 18. The process according to claim 1, wherein the polymeric material comprises about 5% by weight of the sprayable aqueous solution. 19. The process according to claim 1, wherein the particles further comprise a sucrose core. 20. A liquid dishwashing detergent product, comprising:a) a liquid detergent composition; andb) particles insoluble in the liquid detergent composition, wherein the particles comprise a hydrated polymeric coating formed from a sprayable aqueous solution comprising from about 1% to about 30% by weight of a polymeric material, and wherein the polymeric coating and the liquid automatic dishwashing composition comprise observed color with or without whitening selected from the group consisting of blue, blue-green, green, yellow, white, and combinations thereof. 21. The liquid dishwashing detergent product according to claim 20, wherein the polymeric coating comprises about 5% by weight of the particle. 22. The liquid dishwashing detergent product according to claim 20, wherein the polymeric material comprises alkyl cellulose ether, polyvinyl alcohol, alginate or a mixture thereof. 23. A process of improving aesthetics of a liquid dishwashing detergent product, comprising the steps of:a) providing a liquid dishwashing detergent composition; andb) adding solid particles to the liquid dishwashing detergent composition, wherein the particles comprise a hydrated polymeric coating formed from a sprayable aqueous solution comprising from about 3% to about 10% by weight of a polymeric material, wherein the polymeric coating is insoluble in the liquid dishwashing detergent composition but soluble in dishwashing solution, wherein the polymeric material comprises alkyl cellulose ether, polyvinyl alcohol, alginate or a mixture thereof, and wherein the polymeric coating and the liquid automatic dishwashing composition comprise observed color with or without whitening selected from the group consisting of blue, blue-green, green, yellow, white, and combinations thereof. 24. The process according to claim 23, wherein the particles further comprises a sucrose core. 25. The liquid dishwashing detergent product according to claim 12, wherein the polymeric coating and the liquid automatic dishwashing composition comprise observed color combinations of blue:blue, blue:white, green:green, green :white, or green:yellow.
