1. A detergent, washing additive composition, laundry pretreatment composition or cleaner, comprising a color transfer inhibitor in the form of an oligoamide, the oligoamide having at least 750 μmol/g of basic amino groups, as well as customary ingredients compatible with this constituent, wherein the oligoamide consists essentially of repeating units of formulae Ia and/or Ib and optionally branching units of the formulae II and/or II′, wherein A is selected from alkanediyl radicals having 2 to 20 carbon atoms, wherein 1, 2, 3, 4 or 5 nonadjacent CH2 groups can be replaced by a corresponding number of NH groups and/or in which 2 joined together CH2 groups can be jointly replaced by a C5-C7-cycloalkanediyl group, and groups of the formula (A″-O)p-A′, wherein A″ is C2-C4-alkanediyl, and p is an integer in the range from 1 to 20, wherein the repeating units A″-O can be identical or different; A′ is selected from alkanediyl radicals having 2 to 20 carbon atoms, wherein 1, 2, 3, 4 or 5 nonadjacent CH2 groups can be replaced by a corresponding number of NH groups, and/or in which 2 joined together CH2 groups can be jointly replaced by a C5-C7-cycloalkanediyl group; B is selected from a covalent bond, alkanediyl having 1 to 20 carbon atoms, wherein 2 joined together CH2 groups can be jointly replaced by a C5-C7-cycloalkanediyl group, and C6-C14-arylenediyl, which is unsubstituted or has 1 or 2 substituents, which are selected from C1-C4-alkyl, C1-C4-alkoxy and SO3H, and B′ is selected from alkanediyl radicals having 4 to 20 carbon atoms. |
