The use of polycationic condensation products as an additive for detergents or detergent after treatment agents in order to inhibit running of colours and to reduce colour loss

(57) A summary (a) piperazine, 1* アルキル piperazine which has the C* atom 1*25 in an alkyl group, 1, 4* ジアル kill piperazine which have the C* atom 1*25 in an alkyl group, 1, a 4* screw * (3* amino propyl) * piperazine, 1* (2* amino ethyl) piperazine, 1* (2* ヒドロキシアルキル) piperazine which has the C* atom 2*25 in an alkyl group, Imidazole, C*C* アルキル imidazole, or the mixture and (b) アルキ range halo ゲニド of the above-mentioned compound, By making it condense in the molar ratio of 1: 0.8*1: 1.1 with エピハロゲンヒ drine compounds and/or screw * EPO キシド, and forming this condensation product into 4 class using a C*C* alkylating agent by a case, Or Tori Etah Nord amine or Tori isopropanol amine is heated under existence of an acid catalyst, And 1*50 % of the weight of as a dye stability additive to the detergent and the washing post-processing agent of the poly cationic condensation product acquired by forming this condensation product into 4 class using a C*C* alkylating agent / the use and at least one sort of (i) nonionic surface-active agents, (ii) The detergent and the softening rinse agent containing 0.05*2.5 % of the weight of at least one sort of poly cationic condensation products as 0*4.0 % of the weight of anion nature surface-active agents, (iii) color change control, and a color elution reduction nature additive, The washing post-processing agent containing a nonionic surface-active agent and 0.1*2.5 % of the weight of the above-mentioned poly cationic condensation products.
