Patent

CA 2359533

The present invention relates to laundry detergent compositions which can optionally comprise bleach, said compositions comprising from about 0.01 % by weight, of a fabric enhancement system, said fabric enhancement system comprising one or more modified polyamine compounds, said modified polyamine compounds are selected from: i) (PA)w(T)x; ii) (PA)w(L)z; iii) [(PA)w(T)x]y[L]z; and iv) mixtures thereof; wherein PA is a grafted or non- grafted, modified or unmodified polyamine backbone unit, T is an amide-forming polycarboxylic acid crosslinking unit, and L is a non-amide forming crosslinking unit; provided that for compounds of type (i) and (iii) the indices w and x have values such that the ratio of w to x is from 0.8 : 1 to 1.5 : 1; for compounds of type (ii) the indices w and z have values such that said modified polyamine compound comprises from about 0.05 to 2 parts by weight of said L unit; for compounds of type (iii) the indices y and z have values such that said modified polyamine compound comprises from about 0.05 to 2 parts by weight of said L unit.

La présente invention concerne des compositions de détergent à lessive pouvant éventuellement comprendre un agent de blanchiment. Ces compositions comprennent au moins environ 0,01% en masse d'un système renforçateur textile. Ce système renforçateur textile comprend au moins un composé à base de polyamine modifié ou certains de leurs mélanges, les composés à base de polyamine modifié appartenant au groupe des i) (PA)¿w?(T)¿x?; ii) (PA)¿w?(L)¿z?; iii) [(PA)¿w?(T)¿x?]¿y?[L]¿z?; et iv) certains de leurs mélanges. En l'occurrence, "PA" est une unité greffée ou non greffée à ossature de polyamine modifiée ou non modifiée, "T" est une unité de réticulation d'acide polycarboxylique formatrice d'amide, et "L" est une unité de réticulation non formatrice d'amide. Toutefois, pour les composés (i) et (iii), la valeur des indices "w" et "x" est telle que le rapport de w à x est compris de 0,8:1 à 1,5:1. De plus, pour les composés (ii), la valeur des indices "w" et "z" est telle que le composé polyaminique modifié comprend d'environ 0,05 à 2 parts en masse de l'unité "L", et pour les composés (iii), la valeur des indices "y" et "z" est telle que le composé polyaminique modifié comprend d'environ 0,05 à 2 parts en masse de l'unité "L".
