Abstract

A dimensionally stable, single-piece detergent or treatment agent portion having a weight of at least 50 g, having a system for controlling the solubility of the detergent or treatment agent. In washing, treating, or rinsing cycles of a washing machine for textiles, a maximum 50 wt % of the detergent or treatment agent portion dissolves or disperses in municipal water (16° d) at a maximum temperature of 20° C. as dissolves or disperses in municipal water (16° d) at a temperature of 50° C., enabling targeted release of the active substances in the portion during the cycles of a washing or treating program using heated water.

Claims

1-17. -17. (canceled)

18. A dimensionally stable one-piece detergent or treatment agent portion having a weight of at least 50 g, comprising a system to control solubility or dispersibility of the detergent or treatment agent in a wash, treatment, or rinse cycle of a washing machine for textiles, wherein a maximum of 50% by weight of the portion dissolves or disperses in 16°

d tap water at a maximum temperature of 20°

C. as dissolves or disperses in 16°

d tap water at 50°

C. under identical conditions.

19. The detergent or treatment agent portion of claim 18, having a solubility or dispersibility in 16°

d tap water at 15°

C. of less than 0.2 g/100 mL water, and a solubility or dispersibility in 16°

d tap water at 50°

C. of more than 0.35 g/100 mL water.

20. The detergent or treatment agent portion of claim 19, having a solubility or dispersibility in 16°

d tap water at 15°

C. of less than 0.1 g/10 mL water, and a solubility or dispersibility in 16°

d tap water at 50°

C. of greater than 0.12 g/100 mL water.

21. The detergent or treatment agent portion of claim 18, wherein the system to control the solubility or dispersibility of the detergent or treatment agent comprises at least 5% by weight of the portion.

22. The detergent or treatment agent portion of claim 18, wherein the system to control the solubility or dispersibility of the detergent or treatment agent comprises one or more polyethylene glycols, polypropylene glycols, polybutyrates, polyvalent alcohols, sugars, polyurethanes, natural waxes, chemically modified waxes, synthetic waxes, wax alcohols, wax esters, paraffins, polyvinyl alcohols, polyacrylic acids and their derivatives, gelatin, or celluloses.

23. The detergent or treatment agent portion of claim 18, comprising at least 6% by weight of one or more surfactants.

24. The detergent or treatment agent portion of claim 18, comprising a basic detergent for white, colored, sensitive, or wool textiles.

25. The detergent or treatment agent portion of claim 18, further comprising a bleach component, an enzyme, a finishing component, an antimicrobial active ingredient, or a nonionic surfactant.

26. The detergent or treatment agent portion of claim 18, having a weight of 75 g to 1500 g.

29. A kit comprising the detergent or treatment agent portion of claim 18 and a bag of water-permeable material or a container that is rigid in at least some areas and has one or more openings through which liquids but not the detergent portion in undissolved, undispersed, or unpulverized form can enter and leave.

30. The kit of claim 29, wherein the bag or container comprises a device that allows the bag or container to be closed or comprises a cushioning material.

31. A method of washing, treating, or rinsing a textile comprising providing the detergent or cleaning agent portion of claim 18 in an automatic washing machine drum and dosing the detergent or cleaning agent from the portion to wash, treat, or rinse the textile.

32. The method of claim 31, wherein the portion is used in 2 to 60 washing, treating, or rinsing stages.

33. A method of washing, treating, or rinsing a textile comprising providing the kit of claim 29 in an automatic washing machine drum and dosing the detergent or cleaning agent from the portion to wash, treat, or rinse the textile.

34. The method of claim 33, wherein the kit is used in 2 to 60 washing, treating, or rinsing stages.

35. The detergent or cleaning portion of claim 18, capable of use in 2 to 60 washing, treating, or rinsing stages.

27. A method for producing a detergent or treatment agent portion, comprising the steps of:

a) optionally providing a core containing an active ingredient by melt casting, tableting, extruding, or coating a powdered, liquid, pasty, or viscous preparation comprising the active ingredient and positioning the core in a mold;

b) casting in the mold a free-flowing composition comprising an active ingredient that is the same or different from, where present, the active ingredient contained in the core, and solidifying the composition to form a dimensionally stable portion; and

c) optionally coating the dimensionally stable portion from step b) with one or more additional layers,

wherein steps b) and c) comprise curing a free-flowing composition by lowering its temperature, incorporating water of hydration or other solvent components, reacting components in the free-flowing composition, chemical conversion or modification, evaporating water or other solvent components, condensation, irradiation, or compression.

28. The method of claim 27, further comprising the step of applying a barrier layer to a respective outer layer of the portion by melt solidification, incorporation of water of hydration or other solvent components, reaction of components present in the barrier material, chemical conversion or modification, evaporation of water or other solvent components, condensation, irradiation, or compression.
