- the present invention relates to detergent tablets which contain so-called nitrile quats as bleach activators.
- the invention relates to moldings such as detergent tablets, detergent tablets, in particular detergent tablets for machine dishwashing, bleaching tablets or water softening tablets with the bleach activators mentioned.
- the dichotomy between a sufficiently hard molded body and a sufficiently fast disintegration time is a central problem. Since sufficiently stable, that is to say shape and break-resistant molded articles can only be produced by relatively high compression pressures, there is a strong compression of the molded article components and consequent delayed disintegration of the molded article in the aqueous liquor and thus to a slow release of the active substances in the Laundry or cleaning process.
- the delayed disintegration of the moldings has the further disadvantage that conventional detergent tablets cannot be washed in via the induction chamber of household washing machines, since the tablets do not disintegrate into secondary articles that are small enough to pass from the induction chamber into the washing drum in a sufficiently rapid time to be washed in.
- Bleaching agent compositions containing nitrile quat type bleach activators are described in the prior art.

If bleaching catalysts are used in the context of the present invention, the particle size restrictions mentioned above also apply to them.
- a particularly preferred bleach activator used in addition to the cationic nitrile of the formula (I) is N, N, N ', N'-tetraacetylethylene diamine, which is widely used in detergents and cleaners. Accordingly, preferred detergent tablets are characterized in that they contain a cationic nitrile of the formula (I) and tetraacetylethylene diamine (TAED) as bleach activators.
- the weight ratios of “nitrile quat” to TAED are preferably in the range from 1: 2 to 10: 1. In such combinations, 1/3 to 2/3 of the total amount of bleach activator of cationic nitrile of the formula (I) is particularly preferred.

- bleach activator contents of between 0.5 and 10% by weight, preferably between 2 and 8% by weight and in particular between 4 and 7% by weight, are common in typical universal detergent tablets, while bleach tablets contain quite high contents, for example between 5 and 30% by weight, preferably between 7.5 and 25% by weight and in particular between 10 and 20% by weight.
- the person skilled in the art is not restricted in its freedom of formulation and can in this way bleach more or less bleaching detergent tablets, detergent tablets or make bleach tablets by varying the levels of bleach activator and bleach.
- the bleach activator (s) in the detergent tablets according to the invention serve to activate the bleach (s) at lower washing or cleaning temperatures and thus to ensure high bleaching performance even at low temperatures.
- Sodium perborate tetrahydrate and sodium perborate monohydrate are particularly important as bleaching agents.
- Further usable bleaching agents are, for example, sodium percarbonate, peroxypyrophosphates, citrate perhydrates and HO 2 -supplying acidic salts or peracids, such as perbenzoates, peroxophthalates, diperazelaic acid, phthaloiminoperacid or diperdodecanedioic acid. Even when using the bleaching agents, it is possible to dispense with the use of surfactants and / or builders, so that pure bleach tablets can be produced.
- bleaching agents from the group of organic bleaching agents can also be used.
- Typical organic bleaching agents are the diacyl peroxides, such as dibenzoyl peroxide.
- Other typical organic bleaching agents are peroxy acids, examples of which include alkyl peroxy acids and aryl peroxy acids.
- Preferred representatives are (a) the peroxybenzoic acid and its ring-substituted derivatives, such as alkylperoxybenzoic acids, but also peroxy- ⁇ -naphthoic acid and magnesium monophosphate, (b) the aliphatic or substituted aliphatic peroxyacids, such as peroxylauric acid, peroxystearic acid, ⁇ -phthaloxyhexanoic acid ( ⁇ -phthaloxyhexanoic acid) . 1, 4-diacid, N, N-terephthaloyl-di (6-aminopercapronic acid) can be used.
- Chlorine or bromine-releasing substances can also be used as bleaching agents in molded articles for automatic dishwashing. Suitable materials which release chlorine or bromine include, for example, heterocyclic N-bromo- and N-chloramides, for example trichloroisocyanuric acid, tribromoisocyanuric acid,
- Dibromo isocyanuric acid and / or dichloroisocyanuric acid (DICA) and / or their salts with cations such as potassium and sodium are considered.
- Hydantoin compounds such as 1,3-dichloro-5,5-dimethylhydanthoin are also suitable.
- sodium percarbonate is the preferred bleaching agent.
- “Sodium percarbonate” is a non-specific term for sodium carbonate peroxohydrates, which strictly speaking are not “percarbonates” (ie salts of percarbonic acid) but hydrogen peroxide adducts with sodium carbonate.
- the merchandise has the average composition 2 Na 2 C0 3 -3 H 2 O 2 and is therefore not peroxycarbonate.
- Sodium percarbonate often forms a white, water-soluble powder with a density of 2.14 "3 , which easily breaks down into sodium carbonate and bleaching or oxidizing oxygen.
- the industrial production of sodium percarbonate is mainly produced by precipitation from an aqueous solution (so-called wet process).
- aqueous solutions of sodium carbonate and hydrogen peroxide are combined and the sodium percarbonate is precipitated by salting-out agents (predominantly sodium chloride), crystallization aids (for example polyphosphates, polyacrylates) and stabilizers (for example Mg ions).
- the precipitated salt which still contains 5 to 12% by weight of mother liquor, is then filtered off and dried in fluidized bed dryers at 90.degree.
- the bulk weight of the finished Depending on the manufacturing process, the product can fluctuate between 800 and 1200 g / 1.
- the percarbonate is stabilized by an additional coating.
- the detergent tablets according to the invention can be single-phase, i.e. from a premix to a homogeneous molded body. According to the invention, however, it is also possible and preferred to provide multi-phase shaped bodies, where active ingredients can be divided into spatially delimited areas where this appears reasonable.
- two- or multi-phase detergent tablets are preferred in which one phase contains the cationic nitrile of the formula (I) in amounts of 2.5% by weight, preferably 5% by weight and in particular 7 , 5 wt .-%, each based on the weight of the phase, while the other phase (s) is preferably free of the cationic nitrile of the formula (I) and in particular free of all bleach activators.
- an increased content of certain ingredients, in particular bleach activators can be achieved in a single phase if the content of this ingredient is correspondingly reduced in the other phase (s) without the Total content of the shaped body in this active ingredient varies.
- Multi-phase molded bodies have the advantage over single-phase molded bodies that the pH criterion according to the invention can be implemented more easily and universally in one phase than for the entire molded body. Due to the low pH that the phase should have after dissolving in water, the use of more alkaline raw materials fen not possible in unlimited quantities, or to be avoided according to the invention. It may be necessary to add acidifying agents in order to have the cationic nitriles of the formula (I) in the mildly alkaline to slightly acidic medium desired according to the invention. If, however, alkaline raw materials, which cannot be dispensed with, are to be inco ⁇ orated in the agents, then a single-phase tablet would require the use of high amounts of acidifying agents.
- a phase split enables both the stabilization of the cationic nitrile, which is advantageous according to the invention, and the use of alkaline raw materials to be achieved, in that the alkaline raw materials such as carbonates, phosphates, silicates etc. are present in the phase (s) which are free of the cationic nitrile of the formula (I) are.
- Delayed release can be achieved, for example, by coating particles or the entire phase, while accelerated release can be achieved, for example, by adding disintegration aids to a phase.
- the washing or Cleaning liquor has a weakly alkaline or neutral to slightly acidic pH value if only the phase that contains the nitrile dissolves. After dissolving the other phase (s), the pH can then be increased drastically depending on the composition of the phase (s).
- the late release of the cationic nitrile of the formula (I) can also be achieved. If the accelerated dissolution of the other phase (s) compared to the nitrile-containing phase is to provide a high pH value, this must be compensated for by acidifying agents in the nitrile-containing phase, if it is desired that the nitrile should be released in a neutral to slightly acidic medium.

- Zinc compounds can also be used to prevent corrosion on the wash ware.
- the detergent tablets can also contain components that positively influence the oil and fat washability from textiles (so-called soil repellents). This effect becomes particularly clear if a textile is soiled that has already been washed several times beforehand with a detergent according to the invention which contains this oil and fat-dissolving component.
- the preferred oil- and fat-dissolving components include, for example, nonionic cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with a proportion of methoxyl groups of 15 to 30% by weight and of hydroxypropoxyl groups of 1 to 15% by weight, in each case based on the nonionic cellulose ether, and the polymers of phthalic acid and / or terephthalic acid or their derivatives known from the prior art, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or nonionically modified derivatives thereof.

- the agents according to the invention can be colored with suitable dyes.
- Preferred dyes the selection of which is not difficult for the person skilled in the art, have a high storage stability and insensitivity to the other ingredients of the compositions and to light, and no pronounced substantivity to textile fibers or dishes, so as not to dye them.
- the usual way of producing detergent tablets is therefore based on powdery components (“primary particles”) which are agglomerated or granulated by suitable processes to form secondary particles with a larger particle diameter. These granules or mixtures of different granules are then mixed with individual powdery additives and fed to the tableting.
- Another object of the present invention is a process for the production of single or multi-phase detergent tablets by shaping molding one or more particulate premixes in a manner known per se, which is characterized in that the premix for the entire molded article or for at least one of the phases a cationic nitrile of the formula (I)

- Detergent tablets preferred in the context of the present invention are obtained by pressing a particulate premix comprising at least one surfactant-containing granulate and at least one subsequently admixed powdery component.
- the granules containing surfactant can be produced by conventional industrial granulation processes such as compacting, extrusion, mixer granulation, pelletization or fluidized bed granulation. It is advantageous for the later detergent tablets if the premix to be ve ⁇ resses has a bulk density that comes close to the usual compact detergent.
- the particulate premix additionally contains granule (s) containing surfactant and has a bulk density of at least 500 g / 1, preferably at least 600 g / 1 and in particular at least 700 g / 1.
- the surfactant-containing granules also meet certain particle size criteria.
- Methods according to the invention are preferred in which the surfactant-containing granules have particle sizes between 100 and 2000 ⁇ m, preferably between 200 and 1800 ⁇ m, particularly preferably between 400 and 1600 ⁇ m and in particular between 600 and 1400 ⁇ m.

Particularly advantageous processes are therefore characterized in that the surfactant-containing granules contain anionic and / or nonionic surfactants and builders and total surfactant contents of at least 10% by weight, preferably at least 20% by weight and in particular at least 25% by weight.
- the premix Before the particulate premix is pressed into detergent and shaped body, the premix can be "powdered” with finely divided surface treatment agents. This can be of advantage for the nature and physical properties of both the premix (storage, pressing) and the finished detergent tablets. Finely divided powdering agents are well known in the art, mostly zeolites, silicates or other inorganic salts being used. However, the premix is preferably “powdered” with finely divided zeolite, zeolites of the faujasite type being preferred. In the context of the present invention, the term “faujasite-type zeolite” denotes all three zeolites which form the faujasite subgroup of the zeolite structure group 4 (compare Donald W.
- zeolite Y and faujasite and mixtures of these compounds can also be used, the pure zeolite X being preferred.
- Mixtures or cocrystallizates of zeolites of the faujasite type with other zeolites which do not necessarily have to belong to the zeolite structural group 4 can also be used as powdering agents, it being advantageous if at least 50% by weight of the powdering agent is used a zeolite of the faujasite type.
- detergent tablets consist of a particulate premix which contains granular components and subsequently admixed powdery substances, the or one of the subsequently admixed powdery components being a zeolite of the faujasite type with particle sizes below 100 ⁇ m, is preferably below 10 ⁇ m and in particular below 5 ⁇ m and is at least 0.2% by weight, preferably at least 0.5% by weight and in particular more than 1% by weight of the premix to be treated.

These substances have been described above.
- the molded articles according to the invention are first produced by dry mixing the constituents, which can be wholly or partially pregranulated, and then providing information, in particular feeding them into tablets, whereby conventional methods can be used.
- the premix is compacted in a so-called die between two punches to form a solid compressed product. This process, which is briefly referred to as tableting in the following, is divided into four sections: metering, compression (elastic deformation), plastic deformation and ejection.
- the premix is introduced into the die, the filling quantity and thus the weight and the shape of the molded body being formed being determined by the position of the lower punch and the shape of the pressing tool.
- the constant dosing, even at high mold throughputs, is preferably achieved by volumetric dosing of the premix.
- the upper punch touches the premix and lowers further in the direction of the lower punch.
- the particles of the premix are pressed closer together, the void volume within the filling between the punches continuously decreasing. From a certain position of the upper punch (and thus from a certain pressure on the premix), the plastic deformation begins, in which the particles flow together and the molded body is formed.
- the premix particles are also crushed and sintering of the premix occurs at even higher pressures.
- the phase of elastic deformation is shortened further and further, so that the resulting shaped bodies can have more or less large cavities.
- the finished molded body is pressed out of the die by the lower punch and transported away by subsequent transport devices. At this time, only the weight of the molded body is finally determined, because the compacts are due to physical Processes (stretching, crystallographic effects, cooling etc.) can still change their shape and size.
- Tableting takes place in commercially available tablet presses, which can in principle be equipped with single or double punches. In the latter case, not only is the upper stamp used to build up pressure, the lower stamp also moves towards the upper stamp during the pressing process, while the upper stamp presses down.
- eccentric tablet presses are preferably used, in which the punch or stamps are fastened to an eccentric disc, which in turn is mounted on an axis with a certain rotational speed. The movement of these rams is comparable to that of a conventional four-stroke engine.
- the pressing can take place with one upper and one lower punch, but several punches can also be attached to one eccentric disk, the number of die holes being increased accordingly.
- the throughputs of eccentric presses vary depending on the type from a few hundred to a maximum of 3000 tablets per hour.
- rotary tablet presses are selected in which a larger number of dies is arranged in a circle on a so-called die table.
- the number of matrices varies between 6 and 55 depending on the model, although larger matrices are also commercially available.
- Each die on the die table is assigned an upper and lower punch, and again the pressure can be built up actively only by the upper or lower punch, but also by both stamps.
- the die table and the stamps move about a common vertical axis, the stamps being brought into the positions for filling, compaction, plastic deformation and ejection by means of rail-like cam tracks during the rotation.
- these cam tracks are supported by additional low-pressure pieces, low-tension rails and lifting tracks.
- the die is filled via a rigidly arranged feed device, the so-called filling shoe, which is connected to a storage container for the premix.
- the pressure on the premix is individual via the press paths for the upper and lower punches adjustable, whereby the pressure builds up by rolling the stamp shaft heads past adjustable pressure rollers.
- Rotary presses can also be provided with two filling shoes to increase the throughput, with only a semicircle having to be run through to produce a tablet.
- several filling shoes are arranged one behind the other without the slightly pressed first layer being ejected before further filling.
- jacket and dot tablets can also be produced in this way, which have an onion-shell-like structure, the top side of the core or the core layers not being covered in the case of the dot tablets and thus remaining visible.
- Rotary tablet presses can also be equipped with single or multiple tools, so that, for example, an outer circle with 50 and an inner circle with 35 holes can be used simultaneously for pressing.
- the throughputs of modern rotary tablet presses are over one million molded articles per hour.
- Non-stick coatings known from the art are suitable for reducing stamp caking.
- Plastic coatings, plastic inserts or plastic stamps are particularly advantageous.
- Rotating punches have also proven to be advantageous, with the upper and lower punches being designed to be rotatable if possible should.
- a plastic insert can generally be dispensed with.
- the stamp surfaces should be electropolished here.
- Tableting machines suitable in the context of the present invention are available, for example, from the companies Apparatebau Holzwarth GbR, Asperg, Wilhelm Fette GmbH, Schwarzenbek, Hofer GmbH, Weil, Hörn & Noack Pharmatechnik GmbH, Worms, IMA Ve ⁇ ackungssysteme GmbH Viersen, KILIAN, Cologne, KOMAGE, Kell am See, KORSCH Pressen AG, Berlin, and Romaco GmbH, Worms.
- Other providers include Dr. Herbert Pete, Vienna (AU), Mapag Maschinenbau AG, Bern (CH), BWI Manesty, Liverpool (GB), I. Holand Ltd., Nottingham (GB), Courtoy NV, Halle (BE / LU) and Mediopharm Kamnik (SI).

Tablettierwerkmaschinee are, for example, from the companies Adams Tablettierwerkmaschinee, Dresden, Wilhelm Fett GmbH, Schwarzenbek, Klaus Hammer, Solingen, Herber% Söhne GmbH, Hamburg, Hofer GmbH, Weil, Hörn & Noack, Pharmatechnik GmbH, Worms, Ritter Pharamatechnik GmbH, Hamburg, Romaco, GmbH, Worms and Notter negligencebau, Tamm available.
- Other providers are e.g. Senss AG, Reinach (CH) and Medicopharm, Kamnik (SI).
- the molded body can be manufactured in a predetermined spatial shape and a predetermined size. Practically all practical configurations can be considered as the spatial shape, for example, the design as a board, the bar or bar shape, cubes, cuboids and corresponding spatial elements with flat side surfaces, and in particular cylindrical configurations with a circular or oval cross section.
- This last embodiment covers the presentation form from the tablet to to compact cylinder pieces with a ratio of height to diameter above 1.
- the portioned compacts can each be designed as separate individual elements that correspond to the predetermined dosage of the detergents and / or cleaning agents. It is also possible, however, to form compacts which connect a plurality of such mass units in one compact, the portioned smaller units being easy to separate, in particular by predetermined predetermined breaking points.
- the portioned compacts as tablets, in cylinder or cuboid form can be expedient, a diameter / height ratio in the range from about 0.5: 2 to 2: 0.5 is preferred.
- Commercial hydraulic presses, eccentric presses or rotary presses are suitable devices, in particular for the production of such pressed articles.
- the spatial shape of another embodiment of the molded body is adapted in its dimensions to the detergent dispenser of commercially available household washing machines, so that the molded body can be metered directly into the dispenser without metering aid, where it dissolves during the dispensing process.
- the detergent tablets without problems using a metering aid and is preferred in the context of the present invention.
- Another preferred molded body that can be produced has a plate-like or plate-like structure with alternating thick long and thin short segments, so that individual segments of this "bolt" at the predetermined breaking points, which represent the short thin segments, broken off and into the Machine can be entered.
- This principle of the "bar-shaped" shaped body detergent can also be realized in other geometric shapes, for example vertically standing triangles, which are connected to one another only on one of their sides along the side.
- the various components are not pressed into a single tablet, but that shaped bodies are obtained which have several layers. ten, i.e. at least two layers. It is also possible that these different layers have different dissolving speeds. This can result in advantageous application properties of the molded body. If, for example, components are contained in the moldings that mutually influence one another negatively, it is possible to integrate one component in the more rapidly soluble layer and to incorporate the other component in a more slowly soluble layer, so that the first component has already reacted. when the second goes into solution.
- the layer structure of the molded body can take place in a stack-like manner, with the inner layer (s) already loosening at the edges of the molded body when the outer layers have not yet been completely removed, but it is also possible for the inner layer (s) to be completely encased ) can be achieved by the outer layer (s), which prevents the premature dissolving of components of the inner layer (s).
- a molded body consists of at least three layers, i.e. two outer and at least one inner layer, at least one of the inner layers containing a peroxy bleaching agent, while in the case of the stacked molded body the two cover layers and in the case of the shell-shaped molded body the outermost layers, however, are free of peroxy bleach. Furthermore, it is also possible to spatially separate peroxy bleaching agents and any bleach activators and / or enzymes that may be present in a molded body.
- Such multilayer molded bodies have the advantage that they can be used not only via a dispensing chamber or via a metering device which is added to the washing liquor; rather, in such cases it is also possible to put the molded body into direct contact with the textiles in the machine without the risk of bleaching from bleaching agents and the like.
- the bodies to be coated can, for example, be sprayed with aqueous solutions or emulsions, or else they can be coated using the melt coating method. After pressing, the detergent tablets have a high stability.
- the breaking strength of cylindrical shaped bodies can be determined via the measured variable of the diametrical breaking load. This can be determined according to
- ⁇ stands for diametral fracture stress (DFS) in Pa
- P is the force in N that leads to the pressure exerted on the molded body that causes the molded body to break
- D is the molded body diameter in meters and t the height of the molded body.
