The present invention relates to fabric enhancement compositions which provide reduced fabric abrasion damage. The compositions of the present invention comprise: a) 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 about 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 about 2 parts by weight of said L unit; b) from about 1% to about 80% by weight, of a fabric softening active; c) and the balance carriers and adjunct ingredients.

L'invention concerne des compositions d'amélioration de l'aspect des textiles, permettant d'obtenir un endommagement réduit des textiles, consécutif à une certaine abrasion. Ces compositions comprennent: a) environ 0,01 % en poids d'un système d'amélioration de l'aspect des textiles, lequel comporte au moins un composé polyamine modifié, ce composé étant choisi dans le groupe constitué par: i) (PA)¿w?(T)¿x?; ii) (PA)¿w?(L)¿z?; iii) [(PA)¿w?(T)¿x?]¿y?[L]¿z?, ou iv) des mélange de ceux-ci, PA représentant une unité à squelette polyamine, modifiée ou non, greffée ou non, T représentant une unité de réticulation d'acide polycarboxylique formant un amide, et L représentant une unité de réticulation ne formant pas un amide, à condition que, d'une part, pour les composés des types (i) et (iii) les indices w et x possèdent des valeurs telles que le rapport w/x soit compris entre 0,8/1 et 1,5/1, et d'autre part, pour les composé du type (ii), les indices w et z possèdent des valeurs telles que le composé polyamine modifié comprenne entre environ 0,05 et environ 2 parties en poids de l'unité L; b) environ 1 à environ 80 % en poids d'un agent adoucissant de textiles et c) le solde étant constitué par des excipients et des ingrédients d'adjonction.
