Abstract

The aim of the invention is to improve the primary detergency of detergents and cleaning agents, in particular with respect to soils containing oil and/or grease. This is substantially achieved by the incorporation of polymers which can be obtained by the copolymerization of N-vinylpyrrolidone with ethylenically unsaturated compounds that have an amide function, said polymers having an aggregation parameter Xag, where Xag>1 mN/m.

First claim

What is claimed is:

1. A detergent or cleaning agent for the washing of textiles or cleaning of hard surfaces comprising crosslinked polymers obtained by polymerization of N-vinylpyrrolidone with N,N-dimethylacrylamide, and wherein the polymerization further comprises crosslinking monomer ethylene glycol dimethacrylate, wherein the molar ratio of the sum of N-vinylpyrrolidone and N,N-dimethylacrylamide to ethylene glycol dimethacrylate is from 70:1 to 30:1, and wherein the crosslinked polymers have an aggregation parameter X ag , in which X ag is from 3 mN/m to 5 mN/m, wherein the agent comprises a synthetic anionic surfactant selected from the group consisting of alkyl and dialkyl sulfosuccinates and wherein the agent further comprises protease and lipase enzymes.

2. The agent according to claim 1 , wherein the crosslinked polymers contain N-vinylpyrrolidone and N N-dimethylacrylamide in a weight ratio in the range of 99:1 to 50:50.

3. The agent according to claim 1 , wherein the crosslinked polymers have an average molecular weight in the range of 1000 g/mol to 50,000 g/mol.

4. The agent according to claim 1 , wherein the agent contains the crosslinked polymers in quantities of 0.1% by weight to 10% by weight.

5. A method for removing bleach- or enzyme-sensitive soils from textiles or hard surfaces, said method comprising contacting said soils on the textiles or hard surfaces with a detergent or cleaning agent according to claim 1 .

6. A method according to claim 5 , wherein said method is carried out using a household washing machine or dishwasher.
