A detergent or cleaning agent, in particular a cleaning agent for hard surfaces, having at least two phases which are different from one another.

First claim

Opening claim text (preview).

What is claimed is: 1. A detergent or cleaning agent comprising at least one first phase and at least one second phase that is different therefrom, wherein the at least one first phase is solid and the at least one second phase is in a liquid or gel form comprising at least one alkanediol, at least one polymer and at least one organic acid, wherein the at least one polymer comprises 10 to 50 wt % based on the weight of the at least one second phase of gelatin and 1 to 35 wt % based on the weight of the at least one second phase of sulfopolymer the pH of a 1% solution of the at least one second phase in water at 20° C. being 6 or less. 2. The detergent or cleaning agent according to claim 1 , wherein the organic acid has a pKa value from 0 to 8. 3. The detergent or cleaning agent according to claim 1 , wherein the organic acid is selected from citric acid anhydrate, citric acid monohydrate, glutaric acid, tartaric acid, glycolic acid, oxalic acid and/or sulfamic acid. 4. The detergent or cleaning agent according to claim 1 , wherein the pH is in the range from 1 to 5. 5. The detergent or cleaning agent according to claim 1 , wherein the proportion of organic acid is from 5 to 20 wt. % based on the total weight of the at least one second phase. 6. The detergent or cleaning agent according to claim 1 , wherein the at least one second phase also comprises at least one polyvalent alcohol. 7. The detergent or cleaning agent according to claim 1 , wherein the at least one second phase is substantially water-free. 8. The detergent or cleaning agent according to claim 1 , wherein the at least polymer further comprises polyvinyl alcohol. 9. The detergent or cleaning agent according to claim 1 , wherein the at least one alkanediol comprises 2-methyl-2-hydroxymethyl-1,3-propanediol and/or 2-ethyl-2-hydroxymethyl-1,3-propanediol. 10. The detergent or cleaning agent according to claim 9 , wherein the at least one alkanediol comprises 2-methyl-2-hydroxymethyl-1,3-propanediol. 11. The detergent or cleaning agent according to claim 9 , wherein the proportion of 2-methyl-2-hydroxymethyl-1,3-propanediol and/or 2-ethyl-2-hydroxymethyl-1, 3-propanediol is 25 wt. % or less based on the total weight of the at least one second phase. 12. The detergent or cleaning agent according to claim 11 , wherein the proportion of 2-methyl-2-hydroxymethyl-1,3-propanediol and/or 2-ethyl-2-hydroxymethyl-1, 3-propanediol is 20 wt. % or less based on the total weight of the at least one second phase. 13. The detergent or cleaning agent according to claim 1 , wherein the at least one first phase and/or the at least one second phase comprises at least one surfactant. 14. The detergent or cleaning agent according to claim 1 , wherein said detergent or cleaning agent is present in the form of a tablet, the weight ratio of the at least one first phase to the at least one second phase being from 20:1 to 8:1. 15. The detergent or cleaning agent according to claim 1 , wherein said detergent or cleaning agent is present in the form of a tablet, the at least one first phase forming a compressed, solid phase having a depression, and the at least one second phase being introduced into said depression. 16. The detergent or cleaning agent according to claim 1 , wherein said detergent or cleaning agent is for dishwashing. 17. The detergent or cleaning agent according to claim 1 , wherein the at least one first phase is a powder.
