Bleach boosting compounds selected from the group consisting of bleach boosters comprising quaternary imine cations, zwitterions, polyions having a net charge of from about +3 to about - 3 and mixtures thereof, bleaching species comprising oxaziridinium cations, zwitterions, polyions having a net charge of from about +3 to about -3 and mixtures thereof, and mixtures thereof are disclosed. The bleach boosting compounds increase bleaching effectiveness even in lower temperature solutions and provide improved stability toward unwanted bleach boosting compound decomposition. The bleach boosting comprounds are ideally suited for inclusion into bleaching compositions including those with detersive surfactants and enzymes. Also provided is a method for laundering a fabric employing the bleach boosting compounds, and a laundry additive product employing the bleach boosting compounds.

L'invention concerne des composés de renforcement de blanchiment sélectionnés dans le groupe de blanchiment comprenant des cations d'imine quaternaires, des zwittérions, des polyions ayant une charge net d'environ +3 à environ 3 et leurs mélanges, des espèces chimiques de blanchiment comprenant des cations d'oxaziridinium, et leurs mélanges. Les composés de renforcement de blanchiment augmentent l'efficacité du blanchiment même dans des solutions de température inférieure et offrent une stabilité améliorée par rapport aux décompositions indésirées de compositions. Les composés de renforcement de blanchiment sont parfaitement appropriés pour être ajoutés dans compositions de blanchiment y compris celles contenant des agents de surface pour la détersion et les enzymes. Un procédé de blanchiment d'un tissu à l'aide des composés de renforcement de blanchiment, et un produit additif de blanchiment utilisant les composés de renforcement de blanchiment sont décrits.
