Abstract:
A detergent which comprises:(i) 1-50% by weight of at least one nonionic surfactant, (ii) 0-4.0% by weight of an anionic surfactant, (iii) 0.05-2.5% by weight of at least one polycationic condensate obtained by condensing: (a) compounds selected from the group consisting of piperazine, 1-alkylpiperazines having 1 to 25 carbon atoms in the alkyl group, 1,4-dialkylpiperazines having 1 to 25 carbon atoms in the alkyl group, 1,4-bis(3-aminopropyl)piperazine, 1-(2-aminoethyl)piperazine, 1-(2-hydroxyalkyl)piperazines having 2 to 25 carbon atoms in the alkyl group, and mixtures thereof, with (b) compounds selected from the group consisting of alkylene dihalides, epihalohydrins, bisepoxides, and mixtures thereof in a molar ratio of from 1:0.8 to 1:1.1 and, optionally with quaternization of the condensates with C4-C25-alkylating agents; or by heating triethanolamine or triisopropanolamine in the presence of an acidic catalyst and quaternizing the condensates with one or more C4-C25-alkylating agents, and (iv) at least one component selected from the group consisting of an organic builder, an inorganic builder, a bleach, a soil release polymer, an anti-redeposition agent, an enzyme, an inorganic filler, a complexing agent, an optical brightener, a dye, a perfume, a foam suppressant, a corrosion inhibitor, a bleach activator, a bleach catalyst, a phosphate, and a phosphonate.
