The invention relates to a dispenser bottle comprising a receptacle (1) for a first active fluid and at least one second receptacle (2) for a second active substance, wherein both receptacles (1; 2) have respective outlets (3; 4) for the active fluid, said outlets (3; 4) being arranged next to one another in such a way that both active fluids can be applied in a common application field (5) of an application area. The receptacles (1; 2) are embodied as compressible containers and the outlets (3;4) are provided with at least one respective discharge nozzle (6; 7) so that the active fluids are mixed with one another only after exiting from the discharge nozzle (6; 7). The aim of the invention is to improve the dispenser bottle of the aforementioned kind. For this purpose, the nozzle channels (16; 17) of the discharge nozzles (6; 7) taper towards each other or are preferably aligned substantially in parallel. The nozzle channels (16; 17) of the discharge nozzles (6; 7) have a respective reduction of cross-section (18) on the inner periphery of the nozzle channels (16; 17). The reductions of cross-section (18), on sides of the nozzle channels (16; 17) facing each other, have edged transitions, and on the sides of the nozzle channels (16; 17) facing away from each other taper from the influx side towards the center of the nozzle channels (16; 17), i.e., they are provided with a chamfer (18') on the influx side.

Dispenser bottle for at least two active fluids

The invention relates to washing or cleaning agent shaped bodies that are mechanically stable, have an excellent rate of dissolution and a completely novel appearance. The novel washing or cleaning agent shaped bodies comprise solid(s) and gas(es) and optionally other washing or cleaning agent components. The shaped body consists of gas-filled cells (pores) that are defined by solid dividing walls. Preferred washing or cleaning agent shaped bodies in the form of solid foams have a content of 40 to 90 % by weight of one or more water-soluble polymers, 10 to 60 % by weight of one or more substances from the group of builders, acidifying agents, chelate complexing agents, plaque-inhibiting polymers or non-ionic tensides as well as 0 to 50 % by weight of one or more adjuvants and/or fillers.

Washing or cleaning agent shaped bodies

The invention relates to silicic acid ester mixtures containing silicic acid esters of formulae (I) and (II), all 'R's being selected, independently of each other, from the following group: H, the straight-chained or branched, saturated or unsaturated, substituted or unsubstituted C1-6- hydrocarbon radicals and fragrance alcohol radicals and biocide alcohol radicals, m taking on values of 1 to 20 and n taking on values from 2 to 100. These esters of oligosilicic acid with fragrance alcohols or biocide alcohols are characterised by a good hydrolysis stability and can also be used in aqueous media or in processes for producing granulates without undergoing excessive losses of activity.

Silicic acid ester mixtures

The invention pertains to glucans capable of being produced by glucosyltransferase activity of a lactic acid bacterium on a sucrose substrate, the glucan having an average molecular weight between 10 kDa and 1 GDa, consisting essentially of alpha (1,3)- and alpha (1,6)-linked anhydroglucose units (AGU) and to glucansucrases capable of producing these glucans from sucrose. The glucans have thickening and anti-corrosive properties. The glucans can be chemically modified.

Novel glucans and novel glucansucrases derived from lactic acid bacteria

Die Erfindung betrifft wasserlosliche, saure Gruppen enthaltende Pfropf-Copolymerisate mit zumindest teilweise biologischer Abbaubarkeit auf der Basis von Zuckern und monoethylenisch ungesattigten Carbonsauren, Sulfonsauren und/oder Phosphonsauren oder den Salzen dieser Sauren sowie die ggf. weiteren Monomeren. Die Erfindindung betrifft ferner ein Verfahren zur Herstellung dieser Pfropf-Copolymerisate bei Temperaturen bis 200 °C mittels radikalischer Polymerisationsinitatioren, indem eine Gesamtmischung aus 5-60 Gew. % Mono-, Di- und Olygosacchariden, deren Derivaten oder deren Mischungen und 95-40 Gew. % einer Monomermischung, die wenigstens eine monoethylenisch ungesattigte Carbonsaure, wenigstens eine monoethylenisch ungesattigte Sulfonsaure, einen monoethylenisch ungesattigten Schwefelsaureester und/oder Vinylphosphonsaure oder die Salze dieser Sauren mit einwertigen Kationen sowie ggf. weitere Monomere enthalt, polymerisiert wird. Ferner betrifft die Erfindung die Verwendung der Pfropf-Copolymerisate in wasrigen Systemen zur Bindung con mehrwertigen Metallionen, zur Inhibierung der Wasserharte, als Zusatz zu Wasch- und Reinigungsmitteln, als Textilhilfsmittel, Dispergiermittel, insbesondere fur Pigmente sowie als Hilfsmittel bei der Papier- und Lederherstellung.

A method for the preparation of polydicarboxysaccharides is provided wherein polysaccharides, such as starch and starch derivatives, are oxidised in the presence of hypobromite and/or hypoiodite and a low oxidising agent concentration is maintained during the oxidation reaction. The low concentration of oxidising agent can be maintained by adding the oxidising agent during the oxidation reaction. The hypo­bromite or hypoiodite is preferably formed in the reaction medium by oxidation of a catalytic amount of bromide or iodide, either by addition of hypochlorite or by passing an electric current. The product obtained by the method has good calcium and magnesium binding properties and is biodegradable, and thus it is very suitable for use as a builder in detergent compositions.
