Abstract
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.
