Claims
- 1. 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.
- 2. The detergent of claim 1, wherein the condensate is obtained by condensing(a) compounds selected from the group consisting of piperazine, 1-(2-hydroxyethy)piperazine, 1-(2-aminoethyl)piperazine, and mixtures thereof with (b) compounds selected from the group consisting of 1,2-dichloroethane, 1,2-dichloropropane, 1,3-dichloropropane, 1,4-dichlorobutane, epichlorohydrin, bisepoxybutane and mixtures thereof and optionally, (c) quaternizing the condensates with C6-C22-alkyl halides or C8-C22-epoxides or by heating triethanolamine or triisopropanolamine with an acidic catalyst and quaternizing the condensates with C6-C22-alkyl halides or C8-C22-epoxides.
- 3. The detergent of claim 2, wherein the compounds of the group (c) are compounds selected from the group consisting of benzyl chloride, styrene oxide and mixtures thereof.
- 4. The detergent of claim 1, wherein the condensates have a molecular weight of from 500 to 100,000.
- 5. The detergent of claim 1, wherein the condensates have a molecular weight of from 1,000 to 500,000.
- 6. The detergent of claim 1, wherein the degree of quaternization of the amino groups in the condensates is at least 25%.
- 7. The detergent of claim 1, wherein the degree of quaternization of the amino groups in the condensates is at least 50%.
- 8. The detergent of claim 1, wherein the degree of quaternization of the amino groups in the condensates is from 70 to 100%.
- 9. The detergent of claim 1, which further comprises an anionic detergent in an amount up to 2.5% by weight.
