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 invention concerns the use of water-soluble or water-dispersible cross-linked nitrogenated compounds obtained by crosslinking (a) compounds containing at least three NH groups with (b) at least bifunctional crosslinking agents which react with NH groups, in washing and cleaning agents, in particular as soil-release agents. Preferably, the compounds (a) are selected from the group comprising oligo- and polyamines, polyalkylene polyamines, polyamidoamines, polyamidoamines grafted with (poly)ethyleneimine and mixtures thereof.

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: Additives for increasing the solubility of washing powder formulations in water, added in amounts of 0.1-10 wt.%, comprise hydrophobic alkoxylated alcohols with a functionality of at least 3. The alcohols are prepared either by (i) alkoxylating an at least trivalent alcohol with ethylene oxide (EO) and/or propylene oxide (PO) and then rendering the alkoxylated alcohol hydrophobic by reacting it with a 4-32C epoxide and/or styrene oxide, 1-20C alkylating agent or 1-5C fatty acid, or (ii) reacting the alcohol with a 4-32C epoxide or styrene oxide and then alkoxylating the reaction product with EO and/or PO.

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.
