    Abstract: The invention relates to a method for producing anionically modified polymerizates of alkyl-1-vinyl-imidazoles by radically polymerizing alkyl-1-vinyl-imidazoles with anionic monoethylenically unsaturated monomers and optionally, other copolymerisable monomers, in an aqueous solvent, without using polymerisation regulators.

    Abstract: The use of polycationic condensation products which can be obtained by condensing (a) piperazine, 1-alkyl piperazines with 1-25 C atoms in the alkyl group, 1,4 dialkyl piperazines with 1-25 C atoms in the alkyl group, 1,4-bis -(3-aminopropyl) -piperazine, 1-(2-aminoethyl)piperazine, 1-(2-hydroxyalkyl)piperazines with 2-25 C atoms in the alkyl group, imidazole, C1-C25 - alkyl imidazoles or mixtures of cited compounds with (b) alkyl dihalogenides, epihalogenohydrines and/or bis-epoxides in a molar ratio 1 : 0.8 - 1 : 1.1 and possibly quaternization of condensation products with C4-C25 alkylation agents or by heating triethanolamine or triisopropanolamine in the presence of acid catalysts and quaternization of condensation products with C4-C25 alkylation agents as colour fixing agents for detergents and detergent after-treatment agents. Also disclosed are detergents containing i) at least 1-50 wt % of a non ionic tenside ii) 0 - 4.0 wt % of an ionic tenside and iii) 0.05 - 2.5 wt % of polycationic condensation products in the form of an additive inhibiting the running of colours and reducing colour loss, and detergent after-treatment agents containing a fabric softener, a non ionic tenside and O.1 - 2.5 wt % of cited polycationic condensation products.

    Abstract: Additives for increasing the solubility of washing powder formulations in water, added in amounts of 0.1-10 wt.%, comprise crosslinked alkoxylated alcohols prepared either by alkoxylating an alcohol with ethylene oxide (EO) and optionally propylene oxide (PO) and/or butylene oxide (BO) and then cross-linking the alkoxylated alcohol with an at least bifunctional crosslinking agent. Preferably reaction products of polyalkylene glycols with 2-6C alkylene glycol bisglycidyl ethers, or reaction products of polyethylene glycols having a weight average molecular weight of 100-2500 with a butane-1,4-diol glycidyl ether are used. The alkoxylation reaction products are addition reaction products of 1-100 moles EO, 0-30 moles PO and 0-10 moles BO with 1 mole of 1-22C alcohol. The amount of additive added is 0.5-5 wt.%. The washing powders have bulk weights of 550-1000 (at least 700) g/l.

    Abstract: The invention relates to the use of copolymers consisting of (a) between 10 and 95 weight % of at least one non-ionic monomer which has a N-vinyl group and at 25 DEG C has a water solubility of at least 60 g/l, (b) between 5 and 90 weight % of at least one hydrophobic monoethylenically unsaturated monomer which at 25 DEG C has a water solubility of less than 60 g/l, and possibly (c) between 0 and 15 weight % of at least one monoethylenically unsaturated monomer having an ionic or ionisable group and (d) between 0 and 10 weight % of at least one monomer which has at least 2 ethylenically unsaturated groups. Said copolymers are used in detergents, in amounts of between 0.1 and 5 weight % in relation to said detergents, as additive which inhibits greying and promotes dirt removal during washing and as a secondary treatment agent for laundry.
