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.

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.

Abstract: The use of an amine with an average pKA of from 1 to 14 as detergency booster, preferably in textile detergents, especially in color detergents, and detergent formulations containing these amines.

Abstract: The invention relates to a solid textile detergent formulation containing (A) 1-60 wt. % inorganic builders based on crystalline or amorphous aluminosilicates, crystalline or amorphous silicates, carbonates and/or phosphates, (B) 1-40 wt. % of one or several glycin-N, N-diacetic acid derivatives of formula (I), wherein R stands for an organic radical and M means hydrogen or a cation, (C) 0-6 wt. % anionic surfactants with one or several sulphate groups, one or several sulphate groups or one or two carboxylate groups and (D) 0.5-50 wt. % non ionic surfactants.

Abstract: The use of an amine with an average pKA of from 1 to 14 as detergency booster, preferably in textile detergents, especially in color detergents, and detergent formulations containing these amines.

Abstract: A mixture comprising (a) from 0.1 to 99% by weight of at least one polycarboxylate having at least 3 carboxyls, (b) from 0.1 to 99% by weight of at least one amine having a pKa value of more than 9, and (c) from 0.1 to 99% by weight of at least one acid selected from the group consisting of mineral acids and organic acids having one or two carboxyls and not more than 10 carbons, with the proviso that the mixture contains less than 24% by weight of triphosphates, is used in detergent and rinse aid formulations.

Abstract: A solid textile detergent formulation, comprising(A) 1-60% by weight of inorganic builders based on crystalline or amorphous aluminosilicates, crystalline or amorphous silicates, carbonates and/or phosphates,(B) 0.1-25% by weight of one or more glycine-N,N'-diacetic acid derivatives I ##STR1## where R is an organic radical and M is hydrogen or a cation, as organic cobuilders,(C) 1-40% by weight of anionic surfactants and(D) 0.5-30% by weight of nonionic surfactants.

Abstract: In a process and an apparatus for the continuous preparation of N-acylamino carboxylic acids and N-acylamino sulfonic acids, and their alkali metal salts, from the alkali metal salts of amino carboxylic acids and amino sulfonic acids, respectively, and carbonyl halides in a reactor designed as circulating circuit, the reactants are fed for immediate reaction into the circulating circuit, and a part of the product solution corresponding to the amount fed in is continuously discharged from the circulating circuit. The reactants are circulated by a circulating pump. The temperature in the reactors is controlled. The heat produced in the reaction is removed.
