- 4. The water soluble sachet according to claim 1 wherein the encapsulated bleach comprises a clad with a paraffin wax and a core with a bleach.
- 5. The water soluble sachet according to claim 1 wherein the water soluble sachet comprises polyvinyl alcohol and the dishwashing composition is substantially free of an unencapsulated compound containing boron.
- 6. A water soluble sachet comprising a dishwashing composition having:(a) a polymer having a weight average molecular weight of greater than about 2,000 and comprising a positive charge; and (b) a water soluble polymer that reduces phosphate scale formation, a compound that reduces carbonate scale formation, or both wherein the dishwashing composition is a gel composition that is from about 15% to about 80% by weight water.
- 7. The water soluble sachet according to claim 6 wherein the dishwashing composition further comprises a surfactant having a cloud point in water of less than about 60° C.
- 8. The water soluble sachet according to claim 7 wherein the polymer that reduces phosphate scale formation is derived from a monomer having the formula: wherein R1 is a group comprising at least one Sp2 bond, Z is O, N, P, S, or an amido or ester link, A is a mono- or a polycyclic aromatic group or an aliphatic group and each t is independently 0 or 1 and B+ is a monovalent cation.
- 9. The water soluble sachet according to claim 6 wherein the compound that reduces carbonate scale formation is a polyacrylic acid, a copolymer derived from acrylic and maleic acid, a copolymer of acrylic acid and methacrylic acid, a phosphonic acid, polyphosphoric acid, or salts thereof or mixtures thereof.
- 10. The water soluble sachet according to claim 6 wherein the polymer comprising a positive charge is derived from acrylamidopropyl trimethylammonium salt or diallyldimethylammonium salt.
- 11. The water soluble sachet according to claim 6 wherein the dishwashing composition comprises an encapsulated bleach.
- 12. The water soluble sachet according to claim 6 wherein the dishwashing composition is substantially free of unencapsulated compounds containing boron.
- 13. A package comprising:a water soluble sachet comprising a dishwashing composition wherein the dishwashing composition is a gel which comprises an encapsulated bleach and from about 15% to about 80% by weight water.
- 14. The package according to claim 13 wherein the package further comprises instructions not to use a rinse aid composition or conventional water softening salts or both.
- 15. The package according to claim 13 wherein the dishwashing composition comprises:(a) a polymer having a weight average molecular weight of greater than about 2,000 and comprising a positive charge; and (b) a water soluble polymer that reduces phosphate scale formation, a compound that reduces carbonate scale formation, or both.
- 16. The package according to claim 15 wherein the dishwashing composition further comprises a surfactant having a cloud point in water of less than about 60° C.
- 17. The package according to claim 15 wherein the polymer that reduces phosphate scale formation is derived from a monomer having the formula: wherein R1 is a group comprising at least one sp2 bond, Z is O, N, P, S, or an amido or ester link, A is a mono- or a polycyclic aromatic group or an aliphatic group and each t is independently 0 or 1 and B+ is a monovalent cation.
- 18. The package according to claim 15 wherein the compound that reduces carbonate scale formation is a polyacrylic acid, a copolymer derived from acrylic and maleic acid, a copolymer of acrylic acid and methacrylic acid, a phosphonic acid, polyphosphoric acid, or salts thereof or mixtures thereof.
- 19. A method for minimizing spot and film formation, and phosphate and/or carbonate scale formation on glassware being cleaned, comprising the steps of:(a) inserting a water soluble sachet into a dishwashing machine; (b) allowing the water soluble sachet to dissolve; and (c) subjecting the glassware to a dishwashing composition comprising a polymer comprising a positive charge, and a water soluble polymer that reduces phosphate scale formation, a compound that reduces carbonate scale formation, or both, the dishwashing composition being a gel composition comprising from about 15% to 80% by weight water.
- 20. The method according to claim 19 wherein the dishwashing composition has a viscosity greater than about 100 cps and less than about 45,000 cps.
- 21. The method according to claim 19 wherein the dishwashing composition comprises an encapsulated bleach.
- 22. The method according to claim 21 wherein the dishwashing composition is substantially free of an unencapsulated compound containing boron.
