POLYMERIC AGENTS THAT IMPROVE PRIMARY WASHING EFFICIENCY

摘要

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.

主权项

1. A washing agent comprising a polymer selected from the group consisting of poly-(N,N-dimethylacrylamide), and of polymers accessible by copolymerization of N,N-dimethylacrylamide with a comonomer selected from acrylamide, methacrylamide, N,N-disubstituted acrylamide, N,N-disubstituted methacrylamide, N′,N′-disubstituted aminoalkylmethacrylamide, N,N-disubstituted aminoalkylacrylamide, N-acryloylmorpholine, N-acryloylpyrrolidine, N-acryloylpyrrolidone, N-acryloylpiperidone, N-acryloylcaprolactam, N-methacryloylmorpholine, N-methacryloylpyrrolidine, N-methacryloylpyrrolidone, N-methacryloylpiperidone, N-methacryloylcaprolactam, where substituents in the aforesaid substituted compounds are selected from hydrogen, the benzyl group, linear and branched alkyl and alkoxyalkyl groups having 1 to 6 carbon atoms, and mixtures thereof, with the provision that the substituents in the N,N-disubstituted acrylamide are not two methyl groups.
