Abstract

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

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 7 to 35 wt. % polyvinyl alcohol and/or its derivatives,
from 8 to 26 wt. % polyethylene glycol having an average molar mass of from 350 to 450 g/mol,
from 1 to 35 wt. % sulfopolymer
from 10 to 70 wt. % at least one polyhydric alcohol, and
from 0 to 2 wt. % water, 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, and wherein the amount of the polyhydric alcohols is from 45 wt. % to 70 wt. %, based on the total weight of the at least one second phase.

3. The detergent or cleaning agent portion according to claim 2 , wherein the first polyhydric alcohol is a C 3 to C 8 alkanetriol.

4. The detergent or cleaning agent portion according to claim 3 , wherein the first polyhydric alcohol is glycerin and/or 1,1,1-trimethylolpropane and/or 2-amino-2-(hydroxymethyl)-1,3-propanediol.

5. The detergent or cleaning agent portion according to claim 2 , wherein the second polyhydric alcohol is a C 3 to C 8 alkanediol.

6. The detergent or cleaning agent portion according to claim 2 , wherein the two OH groups of the alkanediol are not arranged on immediately adjacent C atoms of the alkyl chain.

7. The detergent or cleaning agent portion according to claim 1 , wherein the at least one second phase has less than 1 wt. % water, based on the total weight of the at least one second phase.

8. The detergent or cleaning agent portion according to claim 1 , wherein the polyethylene glycol has an average molar mass from of approximately 400 g/mol and is present in a total amount of from 10 to 22 wt. %, based on the total weight of the at least one second phase.

9. The detergent or cleaning agent portion according to claim 1 , wherein the at least one first phase and/or the at least one second phase comprises at least one non-ionic surfactant.

10. The detergent or cleaning agent portion according to claim 1 , wherein the at least one second phase comprises the polyvinyl alcohol (PVOH) and/or its derivatives in an amount of from 10 to 20 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 a weight ratio of the entirety of the at least one first phase to the entirety of the at least one second phase is 40:1 to 2:1.

12. The detergent or cleaning agent portion according to claim 11 , wherein the weight ratio of the entirety of the at least one first phase to the entirety of the at least one second phase is 10:1 to 8:1.

13. The detergent or cleaning agent portion according to claim 1 , that is further defined as a dishwashing detergent.

14. The detergent or cleaning agent portion according to claim 1 , wherein the at least one first phase is powdered and free-flowing.

15. A method for automatically cleaning dishes, comprising the step of using the detergent or cleaning agent portion according to claim 1 in a dishwasher.

16. 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;
g) 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.

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 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.

18. 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 8 to 20 wt. % polyvinyl alcohol,
from 10 to 20 wt. % polyethylene glycol having an average molar mass of 400 g/mol,
from 3 to 30 wt. % sulfonic acid group-containing polyacrylate copolymer
from 10 to 65 wt. % of C 3 to C 8 alkanetriol comprising glycerin and/or 1,1,1-trimethylolpropane and/or 2-amino-2-(hydroxymethyl)-1,3-propanediol,
from 15 to 30 wt. % of C 3 to C 8 alkanediol, and
from 0 to 2 wt. % water, each based on the total weight of the at least one second phase.

19. The detergent or cleaning agent portion of claim 18 , wherein the at least one second phase comprises from 15 to 30 wt. % 1,3-propanediol, from 30 to 40 wt. % glycerin, from 5 to 15 wt. % of the sulfonic acid group-containing polyacrylate copolymer, optionally from 2 to 10 wt. % 1,2-propanediol, and optionally 2 to 15 wt. % triethylene glycol, each based on the total weight of the at least one second phase.

20. The detergent or cleaning agent portion of claim 18 , wherein the granular mixture of the solid composition is free-flowing and exhibits an angle of repose of from 26 to 35 when determined after 24 hours following production and storage at 20° C., and wherein the at least one second phase consists of:
1,3-propanediol in an amount of from 24 to 30 wt. %;
glycerin in an amount of from 22 to 40 wt. %;
polyvinyl alcohol in an amount of from 12 to 18 wt. %;
sulfonic acid-containing acrylate copolymer in an amount of 8 wt. %;
polyethylene glycol having an average molar mass of 400 g/mol in an amount of from 6 to 20 wt. %; and
citric acid anhydride in an amount of from 0 to 8 wt. %.
