The present invention relates to the use of a copolymer comprising at least one first monomer and at least one second monomer, said first monomer being selected from the group of acrylate, substituted acrylate, maleate, or substituted maleate, and said second monomer being selected from styrene or substituted styrene, wherein the weight ratio of said first monomer to said second monomer is from 80:20 to 20:80; polyvinyl pyrrolidone; polyvinyl pyridine N-oxide; lignin-sulphonate; polyethylene-imine alkoxylates; and mixtures thereof; in dishwashing cleaning compositions for the removal of grease and oil from plastic dishware. The present invention also relates to a dishwashing cleaning composition, comprising from 0.0001% to 5% by weight of the composition of a copolymer comprising at least one first monomer and at least one second monomer, said first monomer being selected from the group of acrylate, substituted acrylate, maleate, or substituted maleate, and said second monomer being selected from styrene or substituted styrene, wherein the weight ratio of said first monomer to said second monomer is from 80:20 to 20:80, and from 10% to 60% by weight of the composition of a surfactant system, the surfactant system comprising at least 0.5% by weight of the composition of an amine oxide. The present invention also relates to a kit comprising a container and the dishwashing composition, and to a process of cleaning dishware using the dishwashing cleaning composition.

La présente invention porte sur l~utilisation d~un copolymère comprenant au moins un premier monomère et au moins un second monomère, ledit premier monomère étant sélectionné parmi le groupe consistant en acrylate, acrylate substitué, maléate ou maléate substitué, et ledit second monomère étant sélectionné parmi le styrène ou le styrène substitué, où le rapport pondéral dudit premier monomère audit second monomère est compris entre 80:20 et 20:80 ; du pyrrolidone de polyvinyle ; de l~oxyde N de pyridine de polyvinyle ; du sulfonate de lignine ; des alcoxylates de polyéthylène-imine ; et des mélanges de ceux-ci ; dans des compositions de nettoyage pour laver la vaisselle pour retirer la graisse et l~huile des plats en plastique. La présente invention concerne également une composition de nettoyage pour laver la vaisselle, comprenant de 0,0001% à 5% en poids de la composition d~un copolymère contenant au moins un premier monomère et au moins un second monomère, ledit premier monomère étant sélectionné parmi le groupe consistant en acrylate, acrylate substitué, maléate ou maléate substitué, et ledit second monomère étant sélectionné parmi le styrène ou le styrène substitué, où le rapport pondéral dudit premier monomère audit second monomère est compris entre 80:20 et 20:80, et de 10% à 60% en poids de la composition d~un système tensioactif, le système tensioactif comprenant au moins 0,5% en poids de la composition d~un oxyde d~amine. La présente invention concerne également un kit comprenant un conteneur et la composition pour laver la vaisselle, et un procédé de nettoyage de plats à l~aide de la composition de nettoyage pour laver la vaisselle.
