    Abstract: PCT No. PCT/EP97/05744 Sec. 371 Date May 12, 1999 Sec. 102(e) Date May 12, 1999 PCT Filed Oct. 17, 1997 PCT Pub. No. WO98/17764 PCT Pub. Date Apr. 30, 1998The 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)ethyleneimnine, and mixtures thereof

    Abstract: A zwitterionic polyamine comprising a linear or branched hydrophobic polyamine backbone having 2 to 10 tertiary amino nitrogen atoms and a spacer between two tertiary nitrogen atoms wherein the spacer is, for example selected from C8-C16-alkylene, C5-C15-cyloalkylene, wherein in formula (IV) R = C1- to C22-alkyl or C7-C22-aralkyl and n = 3 to 6, at least one tertiary amine end group of the polyamine backbone contains two groups having formula (V) or (VI), wherein A means an ethylene oxide unit, a propylene oxide unit, a unit of butylene oxides and a tetrahydrofuran unit, n is a number of from 1 to 50, X is an anionic group such as -SO3M, with the proviso that in formula (VI) one X may also be hydrogen and M is hydrogen, alkali metal or ammonium, or contains one group of formula (V) or (VI) and one group selected from radicals consisting of formula (VII), C1- to C22-alkyl and C7-C22-aralkyl, the meaning of A and n is the same as in formula (V) or (VI), said zwitterionic polyetherpolyamine having a molecular weight up to 9000 and optionally containing up to 100 % of the nitrogen atoms quaternized, and a process for the production of zwitterionic polyamines by alkoxylating said polyamines, introducing anionic groups into the alkoxylated polyamines and optionally quaternizing them before or after the introduction of anionic groups. The zwitterionic polyamines are used in detergents.
