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 X, where X&#x3e;1 mN/m.

Polymer active ingredients which improve primary detergent power

The primary washing power of washing and cleaning agents was to be improved, in particular with respect to oil- and/or fat-containing stains. This was achieved substantially by the incorporation of polymers that derive from N,N-dimethylacrylamide.
