The invention relates to cleaning formulations and to the use of the cleaning formulations for preventing the discoloration of plastic articles during washing in machine dishwashers. The cleaning formulations comprise the following components: a) copolymers containing al) from 10 to 60% by weight of at least one monomer unit (A) from the group of the monoethylenically unsaturated C3-C10 monocarboxylic and dicarboxylic acids or their anhydrides, a2) from 40 to 90% by weight of at least one monomer unit (B) of the formula (I) (see formula I), where R1, R2 and R3 independently of one another are H, CH3, C2H5, C3H7, COOH or OH, Y is -C(=O)-, -C(=O)-O-, -O-, -O-C(=O)-, -O-C(=O)-O- or -C(=O)-NH-, n is 0 or 1, and R4 is a linear or branched, cyclic or acyclic aliphatic radical having from 7 to 100 carbon atoms, and a3) from 0 to 30% by weight of at least one further monomer unit (C) copolymerizable with the monomer units (A) and (B) and from the group consisting of C1-C6 (meth)acrylic esters, C1-C6 vinyl esters, C2-C8 olefins, styrenes, acrylonitriles, acrylamides, vinylformamides, allyl alcohols, vinylphosphonates, vinyl-substituted heterocycles and unsaturated organosulfonic acids, b) a bleaching system comprising at least one component from the group consisting of bleach, bleach activator and bleaching catalyst.

L'invention concerne des formulations de nettoyants et leur utilisation pour empêcher la décoloration d'articles en matière plastique pendant le processus de nettoyage dans des lave-vaisselle. Lesdites compositions de nettoyants comprennent les constituants suivants : a) des copolymères contenant : a1) entre 10 et 60 % en poids d'au moins un bloc de base monomère (A) du groupe des acides mono- ou dicarboxyliques C¿3?-C¿10? insaturés par voie monéthylénique ou leurs anhydrides ; a2) entre 40 et 90 % en poids d'au moins un bloc de base (B) de formule générale (I) dans laquelle R?1¿, R?2¿ et R?3¿ désignent indépendamment les uns des autres, H, CH¿3?, C¿2?H¿5?, C¿2?H¿7?, COOH ou OH ; Y désigne C(=O)-, -C(=O)-O-, -O-, -O-C(=O)-, -O-C(=O)-O ou C(=O)-NH, n vaut 0 ou 1, R?4¿ désigne un reste aliphatique linéaire ou ramifié, cyclique ou acyclique ayant entre 7 et 100 atomes de carbone et a3) entre 0 et 30 % en poids d'un autre bloc de base monomère (C) copolymérisable avec les blocs de base monomères (A) et (B), provenant du groupe qui comprend (méth)acrylesters C¿1?-C¿6?, vinylesters C¿1?-C¿6?, oléfines C¿2?-C¿8?, styrènes, nitriles acryliques, acylamides, formadinines vinyliques, allylalcools, phosphonates vinyliques, hétérocycles susbtitués par vinyle et acides organosulgoniques insaturés ; b) un système de blanchiment contenant au moins un constituant du groupe des agents de blanchiment, des activateurs de blanchiment et des catalyseurs de blanchiment.
