  • Patent number: 6777530
    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.

  • Patent number: 6331519
    Abstract: A method of boosting the detergency of a detergent, which entails admixing an amine with an average pKA of from 1 to 14 to the detergent, wherein the amine is a polymer containing repeating units corresponding to the formula: —[CH2—CH(NH2)]— produced by at least partial hydrolysis of oligo/polyvinylformamides and co-polymers of vinylformamide wherein 5 to 100% of the nitrogen atoms are present in primary or secondary amino groups.
