Abstract
The present invention relates to dye transfer inhibiting compositions comprising: a) a polymer selected from polyamine N-oxide containing polymers which contain units having the structure formula (I), wherein P is a polymerizable unit, whereto the N--O group can be attached to or wherein the N--O group forms part of the polymerizable unit or a combination of both; A is (a), (b), (c), --O--, --S--, (d); x is =0 or 1; R are aliphatic, ethoxylated aliphatic, aromatic, heterocyclic or alicyclic groups or any combination thereof whereto the nitrogen of the N--O group can be attached or wherein the nitrogen of the N--O group form part of these groups; b) a surfactant system comprising a surfactant selected from nonionic and/or anionic and/or cationic and/or ampholytic and/or zwitterionic and/or semi-polar surfactants.
