Abstract

The primary washing power of detergents and cleaning agents, particularly with regard to protein-containing soiling, was to be improved. This was achieved substantially by incorporating a combination of polyalkoxylated polyamine with alkoxylated C 8 -C 22 alcohol having an average alkoxylation degree in the range from 1 to 5.

First claim

What is claimed is:

1. A cleaning agent comprising a combination of from 0.3% by weight to 20% by weight polyalkoxylated polyamines which are obtainable by reacting polyamines having primary, secondary and tertiary amino groups, wherein the ratio of primary to secondary amino groups is 1:0.7 to 1:1, and wherein the ratio of primary to tertiary amino groups is 1:0.5 to 1:0.8, with alkylene oxide, and from 0.2% by weight to 10% by weight of a first nonionic surfactant selected from the group consisting of alkoxylated C 8 -C 18 alcohols having an average alkoxylation number in the range of 1 to 5; and wherein the agent further comprises a surfactant system comprising:
a) from 0.1% by weight to 18% by weight synthetic anionic surfactants selected from the group consisting of alkyl sulfates, alkenyl sulfates, ether sulfates, α-sulfo esters, sulfosuccinates, and alkylbenzene sulfonates;
b) from 2% by weight to 25% by weight of second nonionic surfactant, different from said first nonionic surfactant, selected from the group of nonionic surfactants consisting of fatty alkyl polyglycosides, fatty alkyl polyalkoxylates, fatty acid polyhydroxyamides, ethoxylation and propoxylation products of fatty alkylamines, vicinal diols, fatty acid alkyl esters, and fatty acid amides.

2. The cleaning agent of claim 1 wherein the alkoxylated C 8 -C 18 alcohol has an average alkoxylation number in the range of 2 to 4.

3. The cleaning agent of claim 1 , characterized in that the N atoms in the polyamines are separated by alkylene groups containing 2 to 12 C atoms.

4. The cleaning agent of claim 1 , characterized in that the polyamines have an average molar mass in the range of 500 g/mol. to 50,000 g/mol., and that the average number of alkoxy groups per primary and secondary amino function in the polyalkoxylated polyamines is 1 to 100.

5. The cleaning agent of claim 1 , characterized in that the alcohols have 12 to 14 C atoms.

6. Method for removing soils, from textiles or hard surfaces, wherein a detergent or cleaning agent comprising a combination of from 0.3% by weight to 20% by weight polyalkoxylated polyamines which are obtainable by reacting polyamines having primary, secondary and tertiary amino groups, wherein the ratio of primary to secondary amino groups is 1:0.7 to 1:1, and wherein the ratio of primary to tertiary amino groups is 1:0.5 to 1:0.8, with alkylene oxide, and from 0.2% by weight to 10% by weight of first nonionic surfactant selected from the group consisting of alkoxylated C 8 -C 18 alcohols having an average alkoxylation number in the range of 1 to 5; and wherein the agent further comprises a surfactant system comprising:
a) from 0.1% by weight to 18% by weight synthetic anionic surfactants selected from the group consisting of alkyl sulfates, alkenyl sulfates, ether sulfates, α-sulfo esters, sulfosuccinates, and alkylbenzene sulfonates;
b) from 2% by weight to 25% by weight of second nonionic surfactant, different from said first nonionic surfactant, selected from the group of nonionic surfactants consisting of fatty alkyl polyglycosides, fatty alkyl polyalkoxylates, fatty acid polyhydroxyamides, ethoxylation and propoxylation products of fatty alkylamines, vicinal diols, fatty acid alkyl esters, and fatty acid amides, is contacted with the soiled textiles or hard surfaces in a detergent or cleaning solution.

7. Method according to claim 6 , characterized in that the concentration of the polyalkoxylated polyamines in the detergent or cleaning solution is 1 mg/L to 500 mg/L, and that the concentration of the alkoxylated C 8 -C 18 alcohol having an average alkoxylation number in the range of 1 to 5 is 1 mg/L to 500 mg/L.
