Use of crosslinked nitrogenous compounds which are soluble or dispersible in water in detergents and cleaners

   
   

The invention relates to the use of crosslinked nitrogenous compounds which are soluble or dispersible in water and are obtainable by crosslinking of (a) compounds containing at least three NH groups with (b) at least bifunctional crosslinkers which react with NH groups, in detergents and cleaners, especially soil release agents. Compounds (a) are preferably selected from the group consisting of oligo- and polyamines, polyalkylenepolyamines, polyamidoamines, polyamidoamines grafted with (poly)ethyleneimine, and mixtures thereof.

L'invenzione riguarda l'uso dei residui azotati uniti con legami atomici incrociati che sono solubili o disperdibili in acqua ed รจ ottenibile unendo con legami atomici incrociati (a) dei residui che contengono almeno tre gruppi del NH con (b) almeno i crosslinkers che reagiscono con i gruppi del NH, in detersivi ed in pulitori, particolarmente olii del fonditore di bifunctional di distacco del terreno. I residui (a) sono scelti preferibilmente dal oligo- del gruppo e dai polyamines consistenti, polyalkylenepolyamines, polyamidoamines, polyamidoamines innestati con (poly)ethyleneimine e loro miscugli.
