Abstract

The present invention relates to compositions comprising water-soluble alkoxylated polyalkyleneimines with a low melting point. More specifically, the present invention relates to compositions comprising water-soluble alkoxylated polyalkyleneimines having an inner polyethylene oxide block comprising 5 to 18 polyethylene oxide units, a middle polyalkylene oxide block comprising 1 to 5 polyalkylene oxide units and an outer polyethylene oxide block comprising 2 to 14 polyethylene oxide units.

First claim

What is claimed is:

1. A cleaning composition comprising:
from about 1% to about 70% by weight of a surfactant system, wherein the surfactant system comprises a detersive surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, ampholytic surfactants, and mixtures thereof; and
from about 0.1% to about 5% by weight of the composition, of an alkoxylated polyalkylenimine of the general formula I

in which the variables are each defined as follows:
R represents identical or different, linear or branched C 2 -C 12 -alkylene radicals or an
etheralkyl unit of formula X:

in which the variables are each defined as follows:
R 10 , R 11 , R 12 represent identical or different, linear or branched C 2 -C 6 -alkylene radicals and d is an integer having a value in the range of from about 0 to about 50;
B represents a continuation of the alkoxylated polyalkylenimine by branching;
y is from about 0 to about 150, z is greater than 0 and less than or equal to about 150;
E is an alkylenoxy unit of the formula II

in which the variables are each defined as follows:
R 1 represents 1,2-propylene;
R 2 represents hydrogen and/or C 1 -C 22 -alkyl and/or C 7 -C 22 aralkyl;
each of m and p independently has a value in the range of from about 5 to about 14;
n is an integer having a value in the range of from about 1 to about 5; and m+p is equal to or greater than about 14.

2. The composition according to claim 1 , wherein the sum of y+z is at least about 1.

3. The composition according to claim 1 , wherein R is ethylene or hexamethylene.

4. The composition according to claim 1 , wherein the alkoxylated polyalkyleneamine comprises a polyalkylenamine that, before alkoxylation, has a weight average molecular weight (Mw) of from about 250 to about 10 000 g/mol.

5. The composition according to claim 1 , wherein up to about 100% of the nitrogen atoms present in the polyalkylenimine are quaternized.

6. The composition according to claim 5 , wherein the degree of quaternization of the nitrogen atoms present in the polyalkylenimine is in the range of from about 10% to about 95%.

7. The composition according to claim 5 , wherein the quaternized polyalkylenimine is sulfatized or transsulfatized.

8. The composition according to claim 1 , further comprising from about 0.001% to about 1% by weight of enzyme.

9. The composition of claim 6 , wherein said enzyme is selected from lipase, amylase, protease, mannanase, or combinations thereof.

10. The composition of claim 1 , further comprising from about 0.1% to about 10% by weight of an additional amine.

11. The composition of claim 10 wherein said additional amine is selected from oligoamines, triamines, diamines, or a combination thereof.

12. The composition of claim 10 wherein said additional amine is selected from tetraethylenepentamine, triethylenetetraamine, diethylenetriamine, or a mixture thereof.

13. The composition of claim 1 further comprising a hueing agent.

14. A method of pretreating or treating a soiled fabric comprising contacting the soiled fabric with the composition of claim 1 .

15. A cleaning composition comprising:
from about 1% to about 70% by weight of a surfactant system, wherein the surfactant system comprises a detersive surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, ampholytic surfactants, and mixtures thereof; and
from about 0.1% to about 5% by weight of a water-soluble alkoxylated polyalkylenimine of Formula IV,

wherein E is an alkylenoxy unit of formula II

in which the variables are each defined as follows:
R 1 represents 1,2-propylene;
R 2 represents hydrogen and/or C 1 -C 4 -alkyl;
each of m and p independently has a value in the range of from about 5 to about 14
n is an integer having a value in the range of from about 1 to about 5; and m+p is equal to or greater than about 14.

16. The composition of claim 1 , wherein said composition comprises from about 5% to about 50%, by weight of the composition, water.

17. The composition of claim 15 , wherein said composition comprises from about 5% to about 50%, by weight of the composition, water.

18. The composition of claim 1 , wherein the surfactant system comprises anionic surfactant.

19. The composition of claim 1 , wherein R 2 is hydrogen.

20. The composition of claim 1 , wherein R represents C 2 -alkylene radicals.
