Abstract

Official abstract text for this publication.

A detergent or cleaning agent, in particular a cleaning agent for hard surfaces, especially an automatic dishwasher detergent, having a water-soluble envelope with a continuously encircling sealing seam and two phases which are different from one another.

First claim

Opening claim text (preview).

What is claimed is: 1. A detergent or cleaning agent portion comprising a water-soluble wrapping having at least one continuous circumferential sealing seam that lies in one plane, and at least one first phase and at least one second phase different therefrom, wherein the at least one first phase comprises a granular mixture of a solid composition, and wherein the at least one second phase comprises: from 10 to 40 wt. % of at least one polymer comprising gelatin or polyvinyl alcohol; from 1 to 35 wt. % of a sulfopolymer from 5 to 75 wt. % of at least one polyhydric alcohol, from 0 to 2 wt. % water, and from 0 to 0.5 wt. % anionic surfactant, each based on the total weight of the at least one second phase. 2. The detergent or cleaning agent portion according to claim 1 , wherein the at least one second phase further comprises at least two polyhydric alcohols, a first polyhydric alcohol being an alkanetriol and a second polyhydric alcohol being an alkanediol. 3. The detergent or cleaning agent portion according to claim 2 , wherein the first polyhydric alcohol is a C 3 to C 10 alkanetriol and wherein the second polyhydric alcohol is a C 3 to C 10 alkanediol. 4. The detergent or cleaning agent portion according to claim 3 , wherein the first polyhydric alcohol is further defined as a C 3 to C 8 alkanetriol. 5. The detergent or cleaning agent portion according to claim 4 , wherein the first polyhydric alcohol is glycerin and/or 1,1,1-trimethylolpropane and/or 2-amino-2-(hydroxymethyl)-1,3-propanediol. 6. The detergent or cleaning agent portion according to claim 3 , wherein the second polyhydric alcohol is further defined as a C 3 to C 8 alkanediol. 7. The detergent or cleaning agent portion according to claim 3 , wherein the two OH groups of the alkanediol are not arranged on immediately adjacent C atoms of the alkyl chain. 8. The detergent or cleaning agent portion according to claim 7 , wherein the two OH groups of the alkanediol are not arranged on immediately adjacent C atoms of the alkyl chain, and wherein three or four carbon atoms are located between the two OH groups. 9. The detergent or cleaning agent portion according to claim 1 , wherein the at least one second phase further comprises a non-ionic surfactant. 10. The detergent or cleaning agent portion according to claim 1 , wherein the at least one polymer comprises gelatin and wherein the at least one second phase further comprises: a polyethylene glycol having an average molar mass of from 1,000 to 2,000 g/mol, where the polyethylene glycol is present in the at least one second phase in an amount of from 5 to 10 wt. %, based on the total weight of the at least one second phase. 11. The detergent or cleaning agent portion according to claim 1 , wherein the sulfopolymer is further defined as a sulfonic acid group-containing acrylate copolymer. 12. The detergent or cleaning agent portion according to claim 1 , wherein the at least one polymer comprises polyvinyl alcohol and wherein the at least one second phase further comprises: a polyethylene glycol having an average molar mass of from 300 to 800 g/mol, where the polyethylene glycol is present in the at least one second phase in an amount of from 10 to 30 wt. %, based on the total weight of the at least one second phase. 13. The detergent or cleaning agent portion according to claim 1 , wherein a weight ratio of the at least one first phase to the at least one second phase is 40:1 to 2:1. 14. The detergent or cleaning agent portion according to claim 1 , wherein the water-soluble wrapping comprises polyvinyl alcohol. 15. The detergent or cleaning agent portion according to claim 1 , that is further defined as a dishwashing detergent. 16. A method for automatically cleaning dishes, comprising the step of using the detergent or cleaning agent portion according to claim 1 in a dishwasher. 17. A method for producing the detergent and/or cleaning agent portion according to claim 1 , the method comprising: a) providing a mold having at least one mold cavity; optionally containing a partition for dividing the base of the mold cavity; b) adding a water-soluble film onto the mold cavity; c) forming an open chamber in the mold cavity by deforming the water-soluble film; d) filling the open chamber with the at least one second phase; e) optionally leaving the at least one second phase to set; f) subsequently filling the open chamber with the at least one first phase; g) providing a second water-soluble film as a cover; h) superimposing the open chamber and the cover; and i) sealing the cover with the open chamber. 18. A method for producing the detergent and/or cleaning agent portion according to claim 1 , the method comprising: a) providing a mold having at least one mold cavity; optionally containing a partition for dividing the base of the mold cavity; b) adding a water-soluble film onto the mold cavity; c) forming an open chamber in the mold cavity by deforming the water-soluble film; d) filling the open chamber with the at least one first phase; e) providing a second mold having at least one second mold cavity; optionally containing a partition for dividing the base of the mold cavity; f) adding a second water-soluble film onto the second mold cavity; g) forming a second open chamber in the second mold cavity by deforming the water-soluble film; h) filling the second open chamber or parts thereof with the at least one second phase; i) optionally leaving the at least one second phase) to set; j) superimposing the two open chambers; and k) sealing the open chambers together.
