    Abstract: The invention concerns polymer and surfactant mixtures containing in suspended form in at least one surfactant between 1 and 50 wt.% of a polymer comprising: a) between 10 and 100 wt.% of at least one vinylimidazole or a derivative thereof, an open-chain or cyclic N-vinylamide, N-vinyloxazolidone, N-vinyltriazole or mixtures of said monomers; b) between 0 and 90 wt.% of other copolymerizable monoethylenically unsaturated monomers; and c) between 0 and 30 wt.% of at least one monomer with at least two ethylenically unsaturated, non-conjugated double bonds. The invention further concerns a process for preparing these mixtures by polymerization of said monomers in a surfactant, and the use of the mixtures as additives for washing agents.

    Abstract: N-benzyliminium salts have formula (I), in which R and R represent independently from each other hydrogen or optionally substituted alkyl, alkenyl, cycloalkyl, aralkyl, heteroaralkyl, aryl or heteroaryl, provided that at least one of the rests R or R has at least 5 C atoms, if it is an aliphatic rest, or at least 7 C atoms, if it is a cyclic rest; R stands for an organic or inorganic substituent; m equals 1, 2 or 3; and X stands for an oxidation-resistant anion, while n indicates the valence of anion X. These N-benzyliminium salts are used as bleach catalysts, in particular in textile washing and bleaching systems.

    Abstract: Described are polycondensation products obtained by condensing (a) butane-1,2,3,4-tetracarboxylic acid, optionally mixed with hydroxycarboxylic acids or other carboxylic acids, with (b) polyhydroxy compounds selected from the group comprising mono-, oligo- and polysaccharides, reduced mono- and oligosaccharides and their amino derivatives, oxidized mono-, oligo- and polysaccharides, alkyl polyglycosides, polyvinyl alcohols and oligoglycerins with more than 2 glycerin units, or mixtures thereof, plus, optionally, (c) up to 20 mole %, relative to component a, of alkylene glycols, polyalkylene glycols or monohydric C4-C20 alcohols, in the ratio, by weight, of a:b from 50:1 to 0.5:1, the condensation products produced having a K-value of 8 to 100 (determined by the H. Fikent method in a 2 % by wt. aqueous solution at 25 DEG C and pH 7 on the Na salts of the condensation products). The invention also concerns the use of the polycondensation products as additives to low-phosphate or phosphate-free washing or cleaning agents in amounts ranging from 0.1 to 30 % by wt. relative to the agent.
