Abstract

The present invention describes multi-phase detergent tablets as well as a method for their production, in which a particulate premix is pressed into tablets which have at least one cavity. Another solid part, which is conical in shape and does not completely fill the part a), is inserted into this cavity.

Description

The present invention relates to detergent tablets, processes for their manufacture and their application.

Detergent tablets are widely described in the prior art are becoming increasingly popular with consumers because of the simple dosage. Tableted detergents have a number of powdered products Advantages: They are easier to dose and handle and because of their compact structure Advantages in storage and transport. There is therefore one extremely broad state of the art for detergent tablets, which itself is also reflected in an extensive patent literature. The Ent is there early developers of tablet-shaped products came across the idea differently set areas of the molded body certain ingredients only under defined conditions release in the wash or cleaning cycle to improve cleaning success ser. In addition to the core / shell Tablets and ring / core tablets, in particular multilayered molded articles, which are offered today for many areas of washing and cleaning or hygiene become. The optical differentiation of products is also becoming increasingly important tion, so that single-phase and single-color moldings in the field of washing and Cleansing was largely replaced by multi-phase moldings. Common in the market are currently two-layer molded articles with a white and a colored phase or with two differently colored layers. There are also point tablets, ring core tablets, coated tablets, etc., which currently have a rather minor meaning.  

Multi-phase cleaning tablets for the toilet are described, for example, in EP 055 100 (Jeyes Group). This document discloses blocks of toilet cleaners that a molded body from a slowly soluble detergent composition comprise, in which a bleach tablet is embedded. This document immediately reveals different forms of multi-phase moldings. The Her position of the molded body is done according to the teaching of this document either by insertion a compressed bleach tablet in a mold and pour this tablet into the Detergent composition, or by pouring some of the detergent composition into the mold, followed by inserting the pressed bleach Ablette and possibly subsequent pouring together with other cleaning agents settlement.

EP 481 547 (Unilever) also describes multi-phase detergent tablets which to be used for automatic dishwashing. These moldings have the Form of core / shell tablets and are obtained by gradually compressing the loading components manufactured: First, a bleaching agent composition is pressed to a shaped body which in a matrix half-filled with a polymer composition is inserted, which is then filled with further polymer composition and into one provided with a polymer jacket molded bleach is pressed. The procedure is then repeated with an alkaline detergent composition, so that there is a three-phase molded body.

Another way of producing optically differentiated detergents and cleaning agents Shaped body is in the international patent applications WO 99/06522, WO 99/27063 and WO 99/27067 (Procter). According to the teaching of these writings a molded body is provided which has a cavity with a solidifying Melt is filled. Alternatively, a powder is filled in and by means of a coating layer attached in the cavity. All three applications have in common that the cavity filling area should not be pressed, because in this way "pressure sensitive" In contents should be spared.  

The way described in the prior art to prepare melts into the tablets are placed or which are poured into moldings, includes a thermal loading load of the ingredients in the melts. In addition, the exact dosage requires flu siger to pasty media as well as the subsequent cooling a high technical Effort that depends in part on the composition of the melt Shrinkage when cooling and the resulting detachment of the filling is made. The filling of cavities with powdery ingredients and the fixie Coating is also complex and has similar stability problems is liable.

The conventional tableting of multilayer tablets takes place in the field of Detergent tablets also have their limits if only one layer should have a small proportion of the total molded body. If you fall below a be if the layer thickness was correct, then there is pressing of one adhering to the rest of the molded body Layer increasingly difficult.

With the help of special transfer and centering devices can be manufactured separately Tablets in larger matrices, in which there is already a particulate premix for large insert the larger tablets and mix them together with the premix to form the shell / core Compress tablets or tablets. This is double Loading the "core" with high pressing pressures is just as disadvantageous as the high equipment Expenditure.

The older German patent application DE 199 09 271.0 (Henkel) therefore suggests as Alterna tivverfahren a process for the production of multi-phase detergents and cleaning agents Shaped body in which a particulate premix is pressed into shaped bodies, on their surfaces optional adhesion promoters are applied, after which further active substances stamping, for example in the form of pre-compressed molded body, is applied. This font also describes the introduction of pre-tableted active substance (mixtures) into cavities of other moldings.  

The present invention was based on the object that in the older German Patent application DE 199 09 271.0 to further develop the method described. In particular it should be possible to dispense with the use of adhesion promoters. Another The object of the present invention was to provide moldings in which also temperature-sensitive ingredients can be brought into defined regions, the delimited region in terms of its size in relation to the overall shaped body should not be subject to any restrictions. On the one hand, an optical Differentiation from conventional two-layer tablets can be achieved, on the other hand should the production of the molded body in large quantities without great technical effort rie function safely without the moldings disadvantages in terms of stability indicate or inaccuracies in the dosage would be feared.

It has now been found that the disadvantages mentioned are avoided if one specifi ell shaped "cores" pressed into a cavity of a pre-compressed molded body. To this In this way the adhesion of the filling is improved even without the use of adhesion promoters, the temperature load of the ingredients excluded and the expenditure on equipment minimized.

In a first embodiment, the present invention relates to detergent tablets which

• a) a pressed part which has at least one cavity,
• b) a further solid part, which is at least partially enclosed in the cavity present,

include, wherein part b) is conical and the cavity in part a) is not complete fills out.

The cavity in the pressed part a) of the shaped bodies according to the invention can be any Have shape. You can cut through the molded body, d. H. an opening to various NEN sides, for example on the top and bottom of the molded body, they can but also a cavity that does not go through the entire molded body, the opening thereof is only visible on one side of the molding.  

The moldings according to the invention can take on any geometric shape where with in particular concave, convex, biconcave, biconvex, cubic, tetragonal, orthor hombic, cylindrical, spherical, segment-like, disc-shaped, tetrahedral, dodecahedral, octahedral, conical, pyramidal, ellipsoid, pentagonal, octagonal and octagonal prismatic and rhombohedral shapes are preferred. Completely irregular too Base areas such as arrow or animal shapes, trees, clouds, etc. can be realized. If the shaped bodies according to the invention have corners and edges, these are preferred wisely rounded. As an additional optical differentiation, an embodiment with rounded corners and chamfered ("chamfered") edges preferred.

Of course, the pressed parts a) of the moldings according to the invention can also be produced in multiple phases. For reasons of procedural economy here, two-layer moldings have proven particularly effective.

The shape of the cavity can also be freely selected within wide limits. Because of Process economics have through holes, the openings of which ge lie opposite surfaces of the moldings, and troughs with an opening on one Molded body proven. Detergent tablets in which the cavity in part a) has the shape of a through hole are preferred embodiment forms of the present invention. In preferred detergent and cleaning agent form bodies, the cavity has the shape of a through hole, the openings of which are located on two opposing shaped body surfaces. The shape of one through hole can be chosen freely, with molded bodies being preferred, in which the through hole is circular, elliptical, triangular, rectangular, qua dramatic, pentagonal, hexagonal, heptagonal or octagonal horizontal sections has. Completely irregular hole shapes such as arrow or animal shapes, trees, clouds etc. can be realized. As with the shaped bodies, in the case of angular ones Holes with rounded corners and edges or with rounded corners and chamfered edges preferred.

The geometric implementation forms mentioned above can be combined as desired combine other. Shaped bodies with a rectangular or square base can  round holes as well as round shaped bodies with achtec holes, with no limit to the variety of possible combinations are. For reasons of process economy and aesthetic consumer perception Shaped articles with a hole are particularly preferred in which the shaped body base area and the hole cross section have the same geometric shape, for example shaped bodies with square base and centrally integrated square hole. Especially ring shaped bodies are preferred, i. H. circular shaped body with a circular hole.

If the above Principle of the hole open on two opposite sides of the molded body is reduced to an opening, mold bodies are obtained. According to the invention Detergent tablets in which the cavity in part a) is in the form of a having holes open on one side are also preferred. As with the "Lochformkör The moldings according to the invention can also be used in this embodiment do not assume any geometric shape, in particular concave, convex, biconcave, biconvex, cubic, tetragonal, orthorhombic, cylindrical, spherical, cylinder segment ment-like, disc-shaped, tetrahedral, dodecahedral, octahedral, conical, pyrami dale, ellipsoidal, five-, seven- and octagonal-prismatic and rhombohedral shapes are preferred. Also completely irregular base areas such as arrow or animal shapes, trees, Clouds etc. can be realized. If the molding has corners and edges, see above they are preferably rounded. Off is an additional optical differentiation leadership form with rounded corners and chamfered ("chamfered") edges in front moves.

The shape of the trough can also be chosen freely, with molded bodies being preferred which at least one trough has a concave, convex, cubic, tetragonal, orthorhombi cal, cylindrical, spherical, segment-like, disc-shaped, tetrahedral, dode cathedral, octahedral, conical, pyramidal, ellipsoid, pentagonal, octagonal and octagonal prismatic and rhombohedral shape can take. Completely irregular Mul too shapes such as arrow or animal shapes, trees, clouds, etc. can be realized. As with the molded bodies, troughs are with rounded corners and edges or with rounded corners and chamfered edges preferred.  

Regardless of the type of cavity (continuous or trough-like), washing or Preferred detergent tablets in which the cavity has a circular cross cut has.

Part b) of the detergent tablets according to the invention is conical forms. The term "conical" in so ver in the context of the present invention stand that the two horizontal outer surfaces of part b) different largest Have diameter. If a longitudinal section is made through part b), then the length is the distance connecting the two edges at the top, longer or shorter than that Length of the corresponding connecting line at the bottom. These routes are called Measured straight lines. So have top or bottom convex or concave curvature the length of the segment is the length of the imaginary straight line that the two Would connect outer edges together. The easiest way to do this is in the case of Explain the "classic" cone of a truncated cone with a circular base: The The diameter of one of the two circular horizontal boundaries is smaller than that of the other (otherwise there would be a cylinder). This principle can of course be based on this apply to all other geometries, for example to square, rectangular, pentagonal, hexagonal and pentagonal or completely irregular bases. You can of course, different geometries can be combined with each other, so that a horizontal boundary surface can be a circle, an ellipse or a diamond, while the other boundary surface is shaped differently, for example quadra table, octagonal or irregular. For non-circular surfaces, the criterion applies that one horizontal "edge connecting line" must be shorter than the other, preferably for each vertical section through part b). The conical shape is clear of part b) also explain as follows: You take the larger area and think a prism with this base. Once the real shape of part b) in this prism "Fits in", part b) is conical for the purposes of the present invention. Is preferred here that part b) does not touch the wall of the imaginary prism at any point, the criterion that a horizontal "edge connecting line" must be shorter than the other for each vertical section through part b), as already stated, applies.  

With the sizes and masses of conventional detergent tablets, which in the Range from 5 to 100 mm, preferably in the range from 7.5 to 75 mm and in particular from 10 to 50 mm and between 10 and 120 g, preferably between 15 and 80 g and in particular between 20 and 50 g, are in particular washing or cleaning preferred shaped tablets, in which the smallest diameter of the conical Part b) a maximum of 3 mm, preferably a maximum of 2.5 mm and in particular a maximum of 2 mm is smaller than its largest diameter. The term "diameter" denotes here again the "shortest edge connecting line" in longitudinal section, whereby in the case of incorrect gel-shaped parts b) this criterion preferably for any vertical section applies.

Part b) of the shaped body according to the invention is at least partially in the cavity of the Part a) included, wherein the cavity is not completely filled and a cavity in the Part a) remains. Depending on the design of the cavity in the pressed part a), part b) can Completely close the cavity, but it is also possible that part b) for example only closes one side of a through hole in part a) and the remaining cavity, which then effectively represents a hollow that forms the cavity. Part b) can also can be used as a closure in a cavity open on one side in part a), whereby a hollow space forms which does not contact any outer surfaces of the molded body. Laundry or detergent tablets, in which part b) closes the cavity in part a) and the remaining cavity is thus completely enclosed by a) and b) are invented preferred according to the invention.

Of course, this embodiment is not for closing troughs moldings limited; rather, there can also be a through hole in the pressed part a) with a correspondingly shaped part b) or with two different parts b) be closed so that a cavity forms inside the tablet. In logi The continuation of the principle mentioned can also be cavities with several openings Seal the openings with one or more parts b). Detergents or cleaning agents Shaped bodies, which are characterized in that the through hole in part a) with two conical parts b) are closed, are particularly preferred.  

The size of the trough or through hole compared to the overall shape body depends on the intended use of the molded body. Depending on with how much more active substance the remaining hollow volume is filled should and whether a smaller or larger amount of active substance should be contained the size of the cavity and the size of the part not completely filling the cavity b) vary. Detergent and cleaning agent forms are independent of the intended use body preferred, in which the volume ratio of pressed part a) to part b) 2: 1 to 100: 1, preferably 3: 1 to 80: 1, particularly preferably 4: 1 to 50: 1 and in particular 5: 1 to 30: 1.

In addition to the volume ratio mentioned, a mass ratio of the two can also be used Parts are specified, the two values on the densities of parts a) and b) correlate with each other. Regardless of the density of the individual part a) or b) are Detergent tablets according to the invention are preferred, in which the Weight ratio of part a) to part (s) b) 1: 1 to 100: 1, preferably 2: 1 to 80: 1, is particularly preferably 3: 1 to 50: 1 and in particular 4: 1 to 30: 1.

Analogous information can also be given for the surfaces, each of part a) or from part b) are visible. Here are detergent tablets before moves, in which the outwardly visible surface of part b) 1 to 25%, preferably 2 to 20%, particularly preferably 3 to 15% and in particular 4 to 10% of the total upper area of the filled molded body

Part b) does not completely fill the cavity in the pressed part a), so that in the inventions a cavity is formed according to the inventive detergent tablets. This cavity can be filled with active substance, see below. The cavity can even a cavity, d. H. be open to one or more sides, but it is also possible and preferred that the cavity completely from parts a) and b) around is closed. Regardless of the design of the cavity, washing or cleaning are Preferred shaped tablets, in which the volume ratio of the parts a) and b) formed cavity to the overall molded body 1: 1 to 50: 1, preferably 2: 1 to 40: 1, particularly preferably 3: 1 to 30: 1 and in particular 4: 1 to 20: 1.  

Part b) and the base molding [part a)] are preferably optically distinguishable colors. In addition to the optical differentiation, application technology advantages can be achieved by different solubilities of the different shaped body areas can be achieved. Detergent tablets in which part b) dissolves faster than part a), are preferred according to the invention. By incorporating certain components, egg on the one hand, the solubility of part b) can be accelerated in a targeted manner, on the other hand, the Release of certain ingredients from part b) for advantages in washing or cleaning lead process. Ingredients that are preferably at least partially located in part b), are, for example, the disintegration aids, surfactants, Enzymes, soil-release polymers, builders, bleaches, bleach activators, bleach kata analyzers, optical brighteners, silver preservatives, etc. The accelerated release of a or more of the active substances mentioned can be used to increase performance the, for example, by enzymes a washing or cleaning process earlier and thus are available longer. Also the premature release of bleach or sau Ren components are easily possible and often with lei when washing or cleaning advantages.

Of course, detergent tablets according to the invention are also molded preferred, in which part b) dissolves more slowly than part a). Again, you can all or some of the ingredients commonly found in washing or cleaning agents be included in part b). Performance benefits from this delayed release can be seen achieve, for example, by using a slower soluble part b) Active substance (s) are only released in later rinses. For example, at machine dishwashing by slower soluble parts b) can be achieved in Rinse aid further active substance (s) is / are available. By additional Leave substances such as nonionic surfactants, acidifiers, soil release polymers, etc. the rinse aid results improve. Incorporation of perfume is also pro easily possible; due to its delayed release, dishwashers can the often occurring "lye smell" when opening the machine can be eliminated. Also at Textile laundry can use effects of the type mentioned, for example by delayed release of cationic surfactants or other textile softeners or Textile auxiliaries. In this way, the household can in the post-treatment course  Washing machine active substance can be applied to the textiles that precede the washing process is difficult or incomplete to apply. In addition to the above Fabric softeners are especially perfumes, optical brighteners, UV protection agents, skin care products, ironing aids, anti-crease agents, swelling and sliding agents, etc. call.

In preferred embodiments of the present invention, the base molding has a high specific weight. Detergent tablets, which are characterized in that the base tablet [part a)] has a density above 1000 kgdm ^-3 , preferably above 1025 kgdm ^-3 , particularly preferably above 1050 kgdm ^-3 and in particular above 1100 kgdm ^-3 , are preferred according to the invention.

Further details on physical parameters of the base molding or the finished one Detergent tablets and information on their manufacture can be found in white ter below. The preferred ingredients of the base tablet are shown below.

Preferred detergent and cleaning agent form in the context of the present invention bodies are characterized in that the basic shaped body builders in amounts of 1 to 100% by weight, preferably from 5 to 95% by weight, particularly preferably from 10 to 90% by weight and in particular from 20 to 85 wt .-%, each based on the weight of the Basic molding, contains.

In the detergent tablets according to the invention, all the usual builders used in washing and cleaning agents, ins So especially zeolites, silicates, carbonates, organic cobuilders and - where no ecological there are prejudices against their use - including phosphates.

Suitable crystalline, layered sodium silicates have the general formula NaMSi _x O _{2x + 1} . H ₂ O, where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20 and preferred values for x are 2, 3 or 4. Such crystalline layered silicates are described, for example, in European patent application EP-A-0 164 514. Preferred crystalline layered silicates of the formula given are those in which M represents sodium and x assumes the values 2 or 3. In particular, both β- and δ-sodium disilicates are Na ₂ Si ₂ O ₅ . yH ₂ O is preferred, wherein β-sodium disilicate can be obtained, for example, by the process described in the international patent application WO-A-91/08171.

Amorphous sodium silicates with a modulus Na ₂ O: SiO ₂ of 1: 2 to 1: 3.3, preferably from 1: 2 to 1: 2.8 and in particular from 1: 2 to 1: 2.6, can also be used are delayed and have secondary washing properties. The delay in dissolution compared to conventional amorphous sodium silicates can be caused in various ways, for example by surface treatment, compounding, compaction / compression or by overdrying. In the context of this invention, the term “amorphous” is also understood to mean “X-ray amorphous”. This means that the silicates in X-ray diffraction experiments do not provide sharp X-ray reflections, as are typical for crystalline substances, but at most one or more maxima of the scattered X-rays, which have a width of several degree units of the diffraction angle. However, it can very well lead to particularly good builder properties if the silicate particles deliver washed-out or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted in such a way that the products have microcrystalline ranges of size 10 to a few hundred nm, values up to max. 50 nm and in particular up to max. 20 nm are preferred. Such so-called X-ray amorphous silicates, which also have a release delay compared to the conventional water glass glasses, are described, for example, in German patent application DE-A-44 00 024. Particularly preferred are compressed / compacted amorphous silicates, compounded amorphous silicates and over-dried X-ray amorphous silicates.

Preferred detergent and cleaning agent form in the context of the present invention bodies are characterized in that the base molding silicate (s), preferably Alkali silicates, particularly preferably crystalline or amorphous alkali disilicates, in quantities from 10 to 60% by weight, preferably from 15 to 50% by weight and in particular from 20 to 40 wt .-%, each based on the weight of the base molding, contains.  

The finely crystalline, synthetic and bound water-containing zeolite used is preferably zeolite A and / or P. As zeolite P, zeolite MAP® (commercial product from Crosfield) is particularly preferred. However, zeolite X and mixtures of A, X and / or P are also suitable. Commercially available and can preferably be used in the context of the present invention, for example a co-crystallizate of zeolite X and zeolite A (approx. 80% by weight zeolite X), which is sold by CONDEA Augusta SpA under the brand name VEGOBOND AX® and by the formula

n Na ₂ O. (1-n) K ₂ O. Al ₂ O ₃ . (2-2.5) SiO ₂ . (3.5-5.5) H ₂ O

can be described. The zeolite can be used both as a builder in a granule Ren compound used, as well as a kind of "powdering" of the whole to be pressed Send mixture are used, usually both ways of incorporation of the zeolite can be used in the premix. Suitable zeolites have a medium one Particle size of less than 10 µm (volume distribution; measurement method: Coulter Coun ter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight bound water.

It goes without saying that the generally known phosphates are also used as buildersub punching possible, provided that such use is not avoided for ecological reasons should be. Among the large number of commercially available phosphates, the Alka limetal phosphates with particular preference for pentasodium or pentapotassium tri phosphate (sodium or potassium tripolyphosphate) in detergents and cleaning agents Industry the most important.

Alkali metal phosphates is the general term for the alkali metal (in particular sodium and potassium) salts of the various phosphoric acids, in which one can distinguish between metaphosphoric acids (HPO ₃ ) _n and orthophosphoric acid H ₃ PO _{4 in} addition to higher molecular weight representatives. The phosphates combine several advantages: They act as alkali carriers, prevent limescale deposits on machine parts or lime incrustations in tissues and also contribute to cleaning performance.

Sodium dihydrogen phosphate, NaH ₂ PO ₄ , exists as a dihydrate (density 1.91 gcm ^-3 , melting point 60 °) and as a monohydrate (density 2.04 gcm ^-3 ). Both salts are white, water-soluble powders, which lose water of crystallization when heated and into the weakly acidic diphosphate (disodium hydrogen diphosphate, Na ₂ H ₂ P ₂ O ₇ ) at 200 ° C, in sodium trimetaphosphate (Na ₃ P ₃ O ₉ ) and Maddrell's salt (see below). NaH ₂ PO _{4 is} acidic; it occurs when phosphoric acid is adjusted to pH 4.5 with caustic soda and the mash is sprayed. Potassium dihydrogen phosphate (primary or monobasic potassium phosphate, potassium biphosphate, KDP), KH ₂ PO ₄ , is a white salt with a density of 2.33 gcm ^-3 , has a melting point of 253 ° [decomposition to form potassium polyphosphate (KPO ₃ ) _x ] and is easily soluble in water.

Disodium hydrogen phosphate (secondary sodium phosphate), Na ₂ HPO ₄ , is a colorless, very easily water-soluble crystalline salt. It exists anhydrous and with 2 mol. (Density 2.066 gcm ^-3 , water loss at 95 °), 7 mol. (Density 1.68 gcm ^-3 , melting point 48 ° with loss of 5 H ₂ O) and 12 mol. Water ( Density 1.52 gcm ^-3 , melting point 35 ° with the loss of 5 H ₂ O), becomes anhydrous at 100 ° and changes to diphosphate Na ₄ P ₂ O ₇ when heated. Disodium hydrogen phosphate is produced by neutralizing phosphoric acid with soda solution using phenolphthalein as an indicator. Dipotassium hydrogen phosphate (secondary or dibasic potassium phosphate), K ₂ HPO ₄ , is an amorphous, white salt that is easily soluble in water.

Trisodium phosphate, tertiary sodium phosphate, Na ₃ PO ₄ , are colorless crystals which, as dodecahydrate, have a density of 1.62 gcm ^-3 and a melting point of 73-76 ° C (decomposition), as decahydrate (corresponding to 19-20% P ₂ O ₅ ) have a melting point of 100 ° C and in anhydrous form (corresponding to 39-40% P ₂ O ₅ ) have a density of 2.536 gcm ^-3 . Trisodium phosphate is readily soluble in water with an alkaline reaction and is produced by evaporating a solution of exactly 1 mol of disodium phosphate and 1 mol of NaOH. Tripotassium phosphate (tertiary or triphase potassium phosphate), K ₃ PO ₄ , is a white, deliquescent, granular powder with a density of 2.56 gcm ^-3 , has a melting point of 1340 ° and is easily soluble in water with an alkaline reaction. It arises e.g. B. when He's heating Thomas slag with coal and potassium sulfate. Despite the higher price, the more soluble, therefore highly effective, potassium phosphates are often preferred over corresponding sodium compounds in the cleaning agent industry.

Tetrasodium diphosphate (sodium pyrophosphate), Na ₄ P ₂ O ₇ , exists in anhydrous form (density 2.534 gcm ^-3 , melting point 988 °, also given 880 °) and as decahydrate (density 1.815-1.836 gcm ^-3 , melting point 94 ° with loss of water) . Substances are colorless crystals that are soluble in water with an alkaline reaction. Na ₄ P ₂ O ₇ is formed by heating disodium phosphate to <200 °, or by reacting phosphoric acid with soda in a stoichiometric ratio and dehydrating the solution by spraying. The decahydrate complexes heavy metal salts and hardness formers and therefore reduces the hardness of the water. Potassium diphosphate (potassium pyrophosphate), K ₄ P ₂ O ₇ , exists in the form of the trihydrate and is a colorless, hygroscopic powder with a density of 2.33 gcm ^-3 , which is soluble in water, the pH value being 1% Solution at 25 ° is 10.4.

Condensation of the NaH ₂ PO ₄ or the KH ₂ PO ₄ results in higher molecular weight sodium and potassium phosphates, in which one can differentiate cyclic representatives, the sodium or potassium metaphosphates and chain-like types, the sodium or potassium polyphosphates. A large number of terms are used in particular for the latter: melt or glow phosphates, Graham's salt, Kurrol's and Maddrell's salt. All higher sodium and potassium phosphates are collectively referred to as condensed phosphates.

The technically important pentasodium triphosphate, Na ₅ P ₃ O ₁₀ (sodium tripolyphosphate), is an anhydrous or non-hygroscopic, water-soluble salt of the general formula NaO- [P (O) (ONa) -O] that crystallizes with 6 H ₂ O. _n -Na with n = 3. In 100 g of water about 17 g dissolve at room temperature, at 20 ° approx. 20 g, at 100 ° around 32 g of the salt free of water; After heating the solution at 100 ° for two hours, hydrolysis produces about 8% orthophosphate and 15% diphosphate. In the production of pentasodium triphosphate, phosphoric acid is reacted with sodium carbonate solution or sodium hydroxide solution in a stoichiometric ratio and the solution is dewatered by spraying. Similar to Graham's salt and sodium diphosphate, pentasodium triphosphate dissolves many insoluble metal compounds (including lime soaps, etc.). Pentapotassium triphosphate, K ₅ P ₃ O ₁₀ (potassium tripolyphosphate), is commercially available, for example, in the form of a 50% by weight solution (<23% P ₂ O ₅ , 25% K ₂ O). The potassium polyphosphates are widely used in the detergent and cleaning agent industry. There are also sodium potassium tripolyphosphates which can also be used in the context of the present invention. These occur, for example, when hydrolyzing sodium trimetaphosphate with KOH:

(NaPO ₃ ) ₃ + 2KOH → Na ₃ K ₂ P ₃ O ₁₀ + H ₂ O

According to the invention, these are exactly like sodium tripolyphosphate, potassium tripolyphosphate or mixtures of these two can be used; also mixtures of sodium tripolyphos phate and sodium potassium tripolyphosphate or mixtures of potassium tripolyphosphate and Sodium potassium tripolyphosphate or mixtures of sodium tripolyphosphate and potassium tri Polyphosphate and sodium potassium tripolyphosphate can be used according to the invention.

Preferred detergent and cleaning agent form in the context of the present invention Bodies are characterized in that the base molding is preferably phosphate (s) Alkali metal phosphate (s), particularly preferably pentasodium or pentapotassium triphosphate (Sodium or potassium tripolyphosphate), in amounts of 20 to 80 wt .-%, preferably from 25 to 75% by weight and in particular from 30 to 70% by weight, in each case based on the Weight of the base molding.

Alkali carriers can be present as further constituents. The following are considered to be alkali carriers for example alkali metal hydroxides, alkali metal carbonates, alkali metal hydrogen carbonates, alkali metal sesquicarbonates, the alkali silicates mentioned, alkali metals silicates, and mixtures of the aforesaid substances, whereby in the sense of this invention adds the alkali carbonates, especially sodium carbonate, sodium hydrogen carbonate or Sodium sesquicarbonate can be used. A builder system is particularly preferred holding a mixture of tripolyphosphate and sodium carbonate. Also special a builder system containing a mixture of tripolyphosphate and natri is preferred umcarbonate and sodium disilicate.  

The base contains particularly preferred detergent tablets molded articles carbonate (s) and / or hydrogen carbonate (s), preferably alkali carbonates, particularly preferably sodium carbonate, in amounts of 5 to 50% by weight, preferably of 7.5 to 40 wt .-% and in particular from 10 to 30 wt .-%, each based on the Ge importance of the base molding.

As organic cobuilders in the washing and cleaning agents according to the invention telformkörper in particular polycarboxylates / polycarboxylic acids, polymeric polycarboxy latex, aspartic acid, polyacetals, dextrins, other organic cobuilders (see below) and phosphonates are used. These classes of substances are described below ben.

Usable organic builders are, for example, those in the form of their sodium salts usable polycarboxylic acids, with such carboxylic acids under polycarboxylic acids can be understood that carry more than one acid function. For example, these are Citro Nenoic acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, Fumaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), if one such use is not objectionable for ecological reasons, as well as mixtures from these. Preferred salts are the salts of polycarboxylic acids such as citric acid, Adi Pinic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures of the sen.

The acids themselves can also be used.

In order to facilitate the disintegration of highly compressed moldings, it is possible to disintegrate on aids, so-called tablet disintegrants, to incorporate them into the disintegration to shorten times. Under tablet disintegrants or disintegrators according to Römpp (9th edition, vol. 6, p. 4440) and Voigt "Textbook of pharmaceutical Technologie "(6th edition, 1987, pp. 182-184) understood auxiliary substances that are necessary for the rapid Disintegration of tablets in water or gastric juice and for the release of the pharmaceuticals in provide resorbable form.

These substances, which are also referred to as "explosives" due to their effect, ver increase their volume when water enters, and on the one hand increases their own volume (Swelling), on the other hand, a pressure can be generated via the release of gases which can break the tablet into smaller particles. Well-known disintegration aid medium are, for example, carbonate / citric acid systems, but also other organic ones Acids can be used. Swelling disintegration aids are, for example synthetic polymers such as polyvinyl pyrrolidone (PVP) or natural polymers or mo  differentiated natural substances such as cellulose and starch and their derivatives, alginates or casein Derivatives.

Cellulose-based disintegrants which can be used in the context of the present invention are also cellulose derivatives which can be obtained from cellulose by polymer-analogous reactions. Such chemically modified celluloses include, for example, products from esterifications or etherifications in which hydroxyl hydrogen atoms have been substituted. However, celluloses in which the hydroxyl groups have been replaced by functional groups which are not bound via an oxygen atom can also be used as cellulose derivatives. The group of cellulose derivatives includes, for example, alkali celluloses, carboxymethyl cellulose (CMC), cellulose esters and ethers and aminocelluloses.

The fragrances can be incorporated directly into the washing and cleaning agents according to the invention be worked, but it can also be advantageous to apply the fragrances to carriers conditions that increase the adhesion of the perfume to the laundry and a slower rate Fragrance release ensures long-lasting fragrance of the textiles. As such carrier materials Cyclodextrins have proven themselves, for example, the cyclodextrin perfume Complexes can also be coated with other auxiliaries.

To improve the aesthetic impression of the agents according to the invention, it can (or Parts of it) can be colored with suitable dyes. Preferred dyes whose Selection presents no difficulty for the expert, has a high storage stability  and insensitivity to the other ingredients of the agent and to Light as well as no pronounced substantivity towards those treated with the means the substrates such as textiles, glass, ceramics or plastic tableware so as not to start them to dye.

The ingredients described above can - as already mentioned - in the basic form be included, but of course also in part b) and / or the filling of the Cavity are incorporated. Preferred in the context of the present invention Detergent tablets are characterized in that the conical Core moldings [part b)] at least one active ingredient from the group of enzymes, tensi de, soil-release polymers, disintegration aids, bleaches, bleach activators, Bleach catalysts, silver preservatives and mixtures thereof.

By dividing the detergent tablets according to the invention into Base moldings [part a)] and conical "core moldings" [part b)] and optionally one "Cavity filling" [part c)] ingredients can be separated from each other, which ent neither to a storage stability-improving separation of incompatible ingredients or to controlled release of certain active substances can be used. In be preferred laundry detergent or cleaning product tablets according to the invention are the three different areas in particular used the active ingredient pairings Bleichmit tel / bleach activator, bleach / enzyme, bleach / silver protectant, bleach tel / fragrance, bleach / optical brightener, bleach / dye, bleach / surfactant, Bleach activator / enzyme, bleach activator / silver protection agent, bleach activator / fragrance, Bleach activator / optical brightener, bleach activator / dye, bleach activator / surfactant or Separate non-ionic surfactant / anionic surfactant from one another to achieve performance advantages achieve. In addition, the controlled release of certain content substances from the individual regions or by specifically varying the solubility of the individual performance benefits can be achieved.

In preferred detergent tablets, the base tablet contains or the conical core molding inserted into the base molding or the cavity filling bleach, while at least one other part contains bleach activators.  

Further preferred detergent tablets are characterized in that that the base molding or the conical core shape inserted into the base molding body or the cavity filling contains bleach while at least one other Contains some enzymes.

Also a separation of bleach and corrosion inhibitors or silver protection agents can be achieved. Detergent tablets in which the basic tablet by or the blended conical core body inserted into the base molding contains, while at least one other part contains anti-corrosion agents are also prefers.

Last but not least, detergent tablets are preferred, in which the Base molding or the conical core molding inserted into the base molding Bleach contains, while at least another part of surfactants, preferably nonio African surfactants, with particular preference for alkoxylated alcohols with 10 to 24 Koh lenstoffatomen and 1 to 5 alkylene oxide units.

Not only can a complete separation of the ingredients be beneficial, also through Varying amounts of individual ingredients in the different shaped body areas beneficial effects can be achieved. Detergent tablets, the are characterized in that the base molding or in the base molding inserted conical core moldings the same active ingredient in different amounts are preferred according to the invention. As examples of ingredients where the Breakdown into the different regions have advantages are disintegration auxiliaries, dyes and fragrances, optical brighteners, polymers, silver protection surfactants and to name enzymes. The term "different quantities" characterizes the Content of the individual molded part of the substance in question, based on the Shaped body area, is therefore a% by weight indication that does not refer to the absolute amounts of the ingredient.  

Since part b) does not completely fill the cavity in part a) according to the invention, it is possible to bring more active substance into the remaining cavity. This can also - how already described above - can be used for further separation of active substances.

All of the ingredients described above can be contained in all different areas of the moldings according to the invention. While part a) of the shaped articles according to the invention can be produced by pressing, tablet processing being an important method in particular, part b) (and also an optional cavity filling which is referred to as part c) can be produced in different ways. Another object of the present invention is also a method for producing multiphase detergent tablets, which comprises the steps

• a) compressing particulate premixes to give moldings which at least have a cavity
• b) Production of moldings which at least partially into the cavity fitable and conical,
• c) inserting the end products of process step b) into the cavity the end products of process step a),
• d) optional aftertreatment of the shaped bodies

is marked.

Regarding the ingredients of the individual particulate premixes or together Settlements that result in the different areas of the molded body apply analogously Executed above for the moldings according to the invention.

Optionally, a further process step can be carried out before or after step c), by introducing further active substance into the part of the cavity, part b) not fills out. Here, this part (referred to above and below as "cavity") can be full are constantly filled, only partially filled or remain empty.

It has proven to be advantageous if this is pressed into basic shaped bodies in step a) Premixed certain physical criteria are sufficient. Preferred methods are at for example characterized in that the particulate premixes in step a)  a bulk density of at least 500 g / l, preferably at least 600 g / l and in particular which have at least 700 g / l.

The particle size of the premix pressed in step a) is also preferably sufficient agreed criteria: processes in which the particulate premixes in step a) Particle sizes between 100 and 2000 μm, preferably between 200 and 1800 μm, particularly preferably between 400 and 1600 μm and in particular between 600 and 1400 microns, are preferred according to the invention. A further restricted particle size ß in the premixes to be pressed can be used to obtain advantageous molded bodies properties can be discontinued. In preferred variants for the Ver The particulate premixes pressed in step a) have a particle size distribution in which less than 10% by weight, preferably less than 7.5% by weight % and in particular less than 5% by weight of the particles larger than 1600 μm or smaller than 200 µm. Narrower particle size distributions are further preferred here. Be Particularly advantageous process variants are characterized in that in step a) pressed particulate premixes have a particle size distribution, at of more than 30% by weight, preferably more than 40% by weight and in particular more than 50% by weight the particles have a particle size between 600 and 1000 microns.

When carrying out process step a), the process according to the invention is not limited to the fact that only a particulate premix to form a shaped body is pressed. Rather, method step a) can also be expanded to the extent that one produces multilayered shaped bodies in a manner known per se by two or preparing several premixes which are pressed together. Here is the first pre-filled slightly pre-compressed to a smooth and parallel to the shape to get the bottom of the body, and after filling the second bottle mixes to the finished molded body. With three- or multi-layer molded articles After each premix addition, a further pre-compression takes place before after addition of the last premix, the molded body is finally pressed. Preferably the first one hend described cavity in the base molding a trough, so that preferred Ausfüh tion forms of the first method according to the invention are characterized in that in step a) multilayered shaped bodies which have a depression, in a manner known per se  Be prepared by making several different particulate premixes be pressed together.

The molded articles according to the invention are first produced in step a) by dry mixing of the ingredients, which may be partially or fully pre-granulated NEN, and then bringing information, in particular pressing to tablets, whereby conventional methods can be used. To manufacture the Invention According to the shaped body, the premix in a so-called matrix between two Stamping compressed to a solid compressed. This process, briefly below called tableting is divided into four sections: dosage, compression (elastic deformation), plastic deformation and ejection.

First, the premix is introduced into the die, the filling quantity and thus the weight and shape of the resulting molded body through the position of the lower one Stamp and the shape of the press tool can be determined. The constant dose tion even at high molding throughputs is preferably a volumetric Dosage of the premix reached. In the further course of tabletting, the Upper stamp the premix and continues to lower towards the lower stamp. At this compression, the particles of the premix are pressed closer together where at the void volume within the filling between the punches continuously decreases. From a certain position of the upper stamp (and thus from a certain pressure on the premix) begins the plastic deformation, in which the particles flow together and the molded body is formed. Depending on the physi properties of the premix, some of the premix particles are also broken down presses and the premix is sintered at even higher pressures. At increasing press speed, i.e. high throughput, the phase of elasti 's deformation is continuously shortened, so that the resulting molded body more or may have smaller cavities. In the last step of tableting the Finished molded articles are pressed out of the die by the lower punch and through subsequent transport devices transported away. At this point, it's just that Weight of the molded body finally determined, because the compacts due to physical  Processes (stretching, crystallographic effects, cooling etc.) their shape and size can still change.

Tableting takes place in commercially available tablet presses, which are basically or double stamps can be equipped. In the latter case, not only the waiter stamp used to build up pressure, also the lower stamp moves during the Pressing process towards the upper punch, while the upper punch presses down. For Small production quantities are preferably used with eccentric tablet presses which the one or more stamps are attached to an eccentric, which in turn on one Axis is mounted with a certain rotational speed. The movement of this Press ram is comparable to the way a conventional four-stroke engine works. The Ver pressing can be done with one upper and one lower stamp, but several can also be used re stamp on an eccentric disk, the number of die holes gen is expanded accordingly. The throughputs of eccentric presses vary depending on the type from a few hundred to a maximum of 3000 tablets per hour.

For larger throughputs, rotary tablet presses are selected, in which on a so-called called matrix table a larger number of matrices is arranged in a circle. The The number of matrices varies between 6 and 55, depending on the model, with larger matrices also are commercially available. Each die on the die table is a top and bottom stamp assigned, again the pressing pressure active only by the upper or lower stamp, but can also be built up by both stamps. The matrix table and the Stamps move around a common vertical axis, the stamp with the help of rail-like cam tracks during the circulation in the positions for Be filling, compression, plastic deformation and discharge. On the stel len, where a particularly serious raising or lowering the stamp is necessary (filling, compacting, ejecting), these cam tracks are replaced by additional che low-pressure pieces, Nierderzugschienen and lifting tracks supported. The filling The matrix is developed via a rigidly arranged feed device, the so-called Filling shoe, which is connected to a reservoir for the premix. The press pressure on the premix is individual via the press paths for upper and lower punches  adjustable, the pressure build-up by rolling the stamp shaft heads past ver adjustable pressure rollers happens.

Rotary presses can also use two filling shoes to increase throughput hen be, with only one semicircle to manufacture a tablet that must. Several fillers are used to produce two- and multi-layer moldings shoes arranged one behind the other without the slightly pressed first layer in front of the further filling is ejected. Appropriate litigation leads to this se also coated and dot tablets can be produced, which have an onion-shell-like structure have, whereby in the case of the point tablets the top of the core or the core layers is not covered and therefore remains visible. Rotary tablet presses are also included Single or multiple tools can be equipped, so that, for example, an outer circle with 50 and an inner circle with 35 holes simultaneously used for pressing the. The throughputs of modern rotary tablet presses are over a million forms body per hour.

When tableting with rotary presses, it has proven to be advantageous to carry out tableting with the smallest possible fluctuations in the weight of the tablet. The fluctuations in hardness of the tablet can also be reduced in this way. Small fluctuations in weight can be achieved in the following ways:

• - use of plastic inserts with small thickness tolerances,
• - low number of revolutions of the rotor,
• - big filling shoes,
• - Matching the filler paddle speed to the speed of the rotor,
• - filling shoe with constant powder height,
• - Decoupling of filling shoe and powder feed.

To reduce the build-up of stamps, all of them can be used in technology known non-stick coatings. Plastic coatings are particularly advantageous, Plastic inlays or plastic stamps. Rotating stamps also have an advantage proven, whereby the upper and lower stamps are rotatable if possible  should. In the case of rotating stamps, a plastic insert is generally not required become. The stamp surfaces should be electropolished here.

It was also shown that long pressing times are advantageous. These can be printed rails, several pressure rollers or low rotor speeds. Since the Fluctuations in the hardness of the tablet are caused by the fluctuations in the pressing forces systems should be used that limit the pressing force. Here elasti cal stamps, pneumatic compensators or resilient elements in the force path be set. The pressure roller can also be designed to be resilient.

The moldings can - as already mentioned above - in a predetermined space shape and predetermined size are manufactured. Practically everyone comes as a spatial form reasonably manageable configurations, for example the training as  Blackboard, the shape of bars or bars, cubes, cuboids and corresponding room elements flat side surfaces and in particular cylindrical configurations with a circle shaped or oval cross section. This last embodiment covers the darbie form from tablets to compact cylinder pieces with a ratio of Height to diameter above 1.

Another preferred shaped body that can be produced has a plate or panel-like structure with alternating thick long and thin short segments, so that individual segments of this "bar" at the predetermined breaking points, the short thin Display segments, can be canceled and entered into the machine. This Principle of the "bar-shaped" shaped detergent can also in other geometri forms, for example vertical triangles that only on one of their Sides are connected alongside one another, can be realized.

But it is also possible that the various components do not become one Tablet are pressed, but that molded bodies are obtained that have several layers ten, i.e. at least two layers. It is also possible that these ver different layers have different dissolving speeds. From this you can advantageous application properties of the molded articles result. If at for example, components are contained in the moldings, which are mutually nega tiv influence, so it is possible to find a component in the more rapidly soluble layer to integrate and incorporate the other component in a slower soluble layer ten, so that the first component has already reacted when the second goes into solution. The layer structure of the moldings can be stacked, with one solder process of the inner layer (s) at the edges of the molded body already takes place, if the outer layers are not yet completely detached, it can also be one complete coating of the inner layer (s) by the outer layer (s) Layer (s) can be reached, which prevents the premature dissolution of Be components of the inner layer (s). Such methods according to the invention, in which in step a) multilayered moldings are produced in a manner known per se, by pressing several different particulate premixes together are preferred embodiments of the present invention.  

As also described above, incompatible ingredients can be identified by the Incor Poration in the different parts a), b) or c) of the moldings according to the invention separate from each other. Such a separation is of course also possible if that part a) is made up of several separate sub-areas. So methods are preferred which are characterized in that in step a) two layers Ge molded body can be produced by two different particulate Vorgemi be pressed together, one of which contains one or more bleaches and the like another contains one or more enzymes and / or bleach activators.

In a further preferred embodiment of the invention, a molded body consists of at least three layers, ie two outer and at least one inner layer, wherein at least one of the inner layers contains a peroxy bleach, while in the case of the stacked shaped body, the two outer layers and in the case of the shell-shaped one Shaped bodies, however, the outermost layers are free of peroxy bleach. Farther it is also possible to use peroxy bleach and any bleach activators present and / or to separate enzymes spatially from one another in a shaped body. Such more Layered moldings have the advantage that they do not have only one induction chamber or via a metering device which is added to the wash liquor can be; rather, it is also possible in such cases to direct the molded body into the machine without causing stains Bleach and the like would be feared.

Similar effects can also be achieved by coating individual components of the detergent and cleaning agent composition to be pressed, or all of them Reach shaped body. For this purpose, the bodies to be coated can be coated with, for example aqueous solutions or emulsions are sprayed, or via the process of Get a coating on the melt coating.

After pressing, the detergent tablets have a high level of 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

Here σ stands for diametral fracture stress (DFS) in Pa, P is the force in N which leads to the pressure exerted on the molded body, which is the Breakage of the shaped body causes, D is the shaped body diameter in meters and t is the Height of the molded body.

In step b), moldings are produced which at least partially extend into the cavity let the molded body a) be inserted and which are conically shaped. These can - as we know ter executed above - close the cavity and a completely enclosed cavity form space. But you can also ver a cavity open on both sides only on one side close so that a cavity remains open on one side, optionally with active substance can be filled.

The molding in step b) can be produced by different methods gene, for example by the tabletting already described for step a). Erfin Process according to the invention, in which the shaped bodies in step b) are produced by tableting are preferred. Analog to the information for process step a) read sen in the event that part b) is also produced by tableting, also for the Particulate composition (s) in process step b) preferred physi Specify parameters: procedures in which the particulate composition (s) tongue (s) in step b) a bulk density of at least 500 g / l, preferably at least 600 g / l and in particular at least 700 g / l has / have and processes in which the particulate composition (s) in step b) particle sizes between 100 and 2000 microns, preferably between 200 and 1800 microns, particularly preferably between 400 and 1600 microns and in particular between 600 and 1400 microns, has / have preferred embodiments of the present invention.  

As an alternative to tableting, other manufacturing processes are also suitable for part b). Preferred processes are characterized in that the shaped bodies in step b) be produced by casting, extrusion, extrusion or sintering.

Depending on the ingredients in part b) of the form produced according to the invention body to be incorporated, there are different manufacturing methods of part b). For example, the pressure load that occurs during tableting can be avoided to protect ingredients, melts can be produced in solidify suitable shapes. In addition to lowering the temperature, such casting processes melting also use other hardening mechanisms, for example time delayed hydration, chemical reaction, radiation curing, etc. Completely analogously, masses can also be produced which are shaped can and then solidify or harden. Unlike liquids such masses are dimensionally stable even in the processable state, d. H. they keep one once given shape, and no shapes are needed that the body "Force" the outer shape until it hardens. While such masses with low ver shaping forces can be brought into the desired shape and the term strand pressing "is misleading because of the low pressures during processing Extrude particulate or plastic masses even at higher pressures. The ex trusion is another preferred manufacturing process for part b). Last but not least it is also possible to fill particle piles of suitable composition in molds and over temperature increases or by radiation, preferably with microwaves, a To bring about sintering and formation of shaped bodies.

The composition of the moldings produced in step b) can be within wide limits can be varied. In principle, all of the ingredients mentioned above can also or can only be incorporated in part b). Used as the preferred manufacturing process for part b) Casting process chosen, so can further auxiliaries and active ingredients from the groups of Waxes, paraffins, polyalkylene glycols, emulsifiers and stabilizers as "matrix" for the ingredients of part b) are selected. These substances are described below ben, since the melt suspensions or emulsions from which part b) can be formed, are also suitable as a further active substance for the cavity filling.  

Depending on the shape of the pressed part a) and the at least partially in an optional filling step for the conical part b) to be inserted the cavity before or after process step c). Closes part b) the cavity in part a) completely and thus forms preferred shaped bodies according to the invention, in which the remaining hollow space is completely enclosed by parts a) and b), so the optional active substance to be introduced into the cavity only before step c) be because the cavity is closed after inserting part b).

However, it is also possible according to the invention to first insert part b) into the pressed part gene and then a remaining cavity at least partially with further active fill up substance, i.e. the optional filling of the cavity with further active substance punch after step c). This procedure can be used, for example Realize molded bodies [parts a)] that form a cavity in the form of a continuous Have hole. Such holes can be closed on one side by suitable parts b) essen, whereby in this process step c) part a) quasi a trough shaped body "a) + b)" is formed. The trough formed in this way then represents the remaining one Cavity, which can optionally be filled with additional active substance. If it is ge is wanted, a further process step c) can follow process step c) ß, so that ultimately a basic molded body with a through hole through two parts b) is closed, with a cavity due to the conical shape of the parts b) remains, which can be filled with active substance before the final sealing.

As already mentioned, the free space due to the special shape of the insert zenden parts b) between the base molding a) and conical "core molding" b) ver remains, can optionally be filled with further active substance. This other active substance can completely fill the remaining cavity; but it is also possible that a Part of the cavity remains unfilled. In the context of the present invention, it is before that at least 50%, preferably at least 60% and in particular at least 70% of the cavity volume can be filled with further active substance. Here are Detergent tablets are preferred in which the volume ratio of unfilled cavity to the active substance contained in this room 1: 1 to 100: 1,  preferably 1.1: 1 to 50: 1, particularly preferably 1.2: 1 to 25: 1 and in particular 1.3: 1 to Is 10: 1. In this terminology, a volume ratio of 1: 1 means that the Cavity is completely filled.

Depending on the size of the hollow remaining between parts a) and b) space, the density of the molded body, the density of the active substance in the hollow space and the The degree of filling of the cavity can be reduced by the proportion of the further active substance in the hollow space make up different proportions of the overall molded body. Here are washing or cleaning preferred moldings, in which the weight ratio of moldings to the active substance contained in the cavity 1: 1 to 100: 1, preferably 2: 1 to 80: 1, be is particularly preferably 3: 1 to 50: 1 and in particular 4: 1 to 30: 1. In the above defined weight ratio is the ratio of the mass of the not with further shaped substance filled with active substance {mass of the "basic shaped body" [part a)] plus mass of part b)} to the mass of the cavity filling.

By suitable packaging of the shaped body and active substance, the time, to which the substance contained in the cavity is released can be predetermined. At for example, the active substance can have direct contact with the application liquor (ie not completely enclosed by parts a) and b)) and almost instantly soluble be so that the active substance contained in the cavity right at the beginning of the washing or Cleaning course is dosed into the washing or cleaning liquor. Alternatively, you can the substance is enclosed by parts a) and b) or is so poorly soluble, that only the molded body is dissolved and the active substance contained in the cavity is released by this or only after a delay.

Depending on this release mechanism, moldings can be made, for example realize in which the active substance contained in the cavity in the cleaning liquor is dissolved before the constituents of the shaped body are dissolved or after this happened. On the one hand, detergent tablets are preferred which are characterized in that the active substance contained in the cavity quickly ler solves than the base molding [part a)].  

But also detergent tablets, in which the ent in the cavity holding active substance dissolves more slowly than the basic tablet [part a)], are preferred Embodiments of the present invention.

The optional filling of the cavity volume preferably contains at least At least one active substance, but can also be a mixture of several active substances hold. Just like part b) are active substances for incorporation into the cavity Filling active substances suitable, which contain ingredients from part a) undesired In enter into interactions. In particular, preferred ingredients for cavity filling are those that are caused by the tabletting of part a) or the manufacturing process of part b) ne would be influenced negatively. Such active substances are, for example, surfactants, bleaching agents tel, bleach activators, bleach catalysts, enzymes, corrosion inhibitors and / or Sil Protective agents, perfume, alkali carriers or acidifying agents. The individual substances are described in detail above. Procedures where the cavity is before or after Step c) with at least one active substance from the group of bleaching agents, bleaching agents vators, enzymes, pH adjusting agents, fragrances, perfume carriers, fluorescent agents, dyes, Foam inhibitors, silicone oils, anti-redeposition agents, optical brighteners, graying ungsinhibitors, color transfer inhibitors and corrosion inhibitors are filled preferred embodiments of the present invention.

The cavity sensor can take a wide variety of forms, for example partially Chen-like (powdery or granular), gel-like, liquid or plastic. The cavity Filling does not have to consist entirely of active substance, for example also use active substances on carrier materials or in carrier matrices. Not too lastly, there are also thin to highly viscous or pasty solutions, suspensions or Emulsions of active substances in solvents or solvent mixtures as Cavity filling can be used.

It is imminent for filling the remaining cavity with further active substance moves that the cavity sensor is introduced into the cavity in a flowable form. At Solid active substances or preparations can introduce the particles into the cavity and subsequently by suitable measures, for example fixation with a coating  layer to be attached. In cases where the cavity is closed to the outside, the attachment can of course also be dispensed with. Analog execution conditions apply to flowable cavity fillings in liquid, gel-like, pasty or plati form, which is caused by hardening, for example solidification of melts, evaporation of Solvents, crystallization, polymerization, pseudo-plastic property changes fixed in the cavity by changing shear forces or by special binders can, if this is necessary or desired.

The void fill may contain particulate solids. These particles can with all processes of the prior art can be produced, for example by spraying drying, granulation, encapsulation, agglomeration, granulation, pelleting, extrusi on, roller compaction, etc. If desired, the particles can be inco ration of binders or by forming a coating over the particles attached to the cavity.

If different particle mixtures are used as cavity filling, then the different particulate cavity fillings have different particle sizes have, for example, in such a way that the first cavity filling a medium particle size has 5%, preferably 10%, particularly preferably 15% and in particular 20% is above the average particle size of the second filling. The term "medium particle size "or" average particle size "refers to the mesh size an imagi granular sieve through which 50% by weight of the particles would fall through. This value can be by sieve analysis with several sieves of different mesh sizes (for example 5, 6 or 7 sieves).

The bulk density of the different particulate cavity fillings can also be un be different. Here, too, it is preferred if the first cavity filling is a bulk has weight that 5%, preferably 10%, particularly preferably 15% and in particular 20% above the bulk density of the second filling.

Particularly preferred particulate compositions (cavity fillings) to be introduced into the cavity (s) of the moldings according to the invention are those which contain surfactants, it being preferred to provide these surfactants for automatic dishwashing agents in a solution-delayed form in order to release the surfactants from the cavity filling can only be reached in rinse aid. Rinse aid particles such as are described in the older German patent application DE 199 14 364.1 (Henkel KGaA) have proven particularly useful for this purpose. Such particles which are particularly preferably introduced into the cavity consist of 0 to 90% by weight of one or more carrier materials, 5 to 50% by weight of one or more coating substances with a melting point above 30 ° C., 5 to 50% by weight one or more active substances and 0 to 10% by weight of further active substances and auxiliaries, so that processes are preferred in which the cavity is filled with particles which consist of

• a) 0 to 90% by weight of one or more carrier materials,
• b) 5 to 50% by weight of one or more coating substances with a melting point above 30 ° C,
• c) 5 to 50 wt .-% of one or more active substances and
• d) 0 to 10% by weight of further active ingredients and auxiliaries

consist.

Reference is expressly made to the disclosure of the aforementioned document men. Nevertheless, the most important ingredients of these are preferred in the cavity bringable "rinse aid particles" described below. Coming as carriers a) all substances that are solid at room temperature are possible. Usually you will be there Select fabrics that have an additional effect in the cleaning process, whereby Offer builders in particular. In preferred particulate rinse aids for The cavity is filled with substances from the group of water-soluble materials Chen detergent and detergent ingredients, preferably the carbonates, hydrogen carbonates, sulfates, phosphates and the organic oligocar solid at room temperature bonic acids in amounts of 55 to 85 wt .-%, preferably from 60 to 80 wt .-% and in particular from 65 to 75% by weight, based in each case on the particle weight.

The preferred carriers mentioned have already been described in detail above ben.  

To the coating substances b), which are preferred according to the invention as the filling of the cavity used active substance particles are used, different requirements on the one hand the melting or solidification behavior, on the other however also the material properties of the casing in the solidified state, i. H. in the Affect active substance particles. Because the active substance particles during transport or storage To be permanently protected against environmental influences, the coating substance must have a high level Stability against, for example, shock loads occurring during packaging or transport gene. The coating substance should either be at least partially elastic or too have at least plastic properties in order to avoid an impact load to react elastic or plastic deformation and not to break. The shell substance should have a melting range (solidification range) in such a temperature range have, in which the active substances to be coated do not have too high a thermal load get abandoned. On the other hand, however, the melting range must be sufficiently high in order to still effective protection for the at least slightly elevated temperature to offer included active substances. According to the invention, the coating substances have one Melting point above 30 ° C.

It has proven to be advantageous if the coating substance does not have a sharply defined one Melting point shows how it usually occurs with pure, crystalline substances, but may have a melting range spanning several degrees Celsius.

The coating substance preferably has a melting range which is between approximately 45 ° C. and is about 75 ° C. In the present case, this means that the melting range within the specified temperature interval occurs and does not denote the width of the Melting range. The width of the melting range is preferably at least 1 ° C. preferably about 2 to about 3 ° C.

The properties mentioned above are usually fulfilled by so-called waxes. "Waxing" is understood to mean a number of natural or artificially obtained substances, which usually melt above 40 ° C without decomposition and a little above the Melting point are relatively low viscosity and not stringy. You assign one strongly temperature-dependent consistency and solubility.  

According to their origin, the waxes are divided into three groups, the natural waxes, chemically modified waxes and synthetic waxes.

Natural waxes include, for example, vegetable waxes such as candelilla wax, Carnauba wax, Japanese wax, esparto grass wax, cork wax, guaruma wax, Rice germ oil wax, sugar cane wax, ouricury wax, or montan wax, animal waxes such as beeswax, shellac wax, walrus, lanolin (wool wax), or pretzel fat, Mineral waxes such as ceresin or ozokerite (earth wax), or petrochemical waxes such as Petrolatum, paraffin waxes or micro waxes.

The chemically modified waxes include hard waxes such as Montanester waxes, Sassol waxes or hydrogenated jojoba waxes.

Synthetic waxes generally include polyalkylene waxes or Understand polyalkylene glycol waxes. Connections can also be used as covering materials from other classes of substances that meet the stated softening point requirements fulfill. Suitable synthetic compounds have, for example, higher esters of Phthalic acid, especially dicyclohexyl phthalate, commercially available under the name Unimoll® 66 (Bayer AG) is available. Synthetic ones are also suitable Waxes from lower carboxylic acids and fatty alcohols, for example dimyristyl tartrate, the is available under the name Cosmacol® ETLP (Condea). Are reversed too synthetic or semi-synthetic esters from lower alcohols with fatty acids from native Sources can be used. Tegin® 90 (Goldschmidt), for example, falls into this class of substances Glycerol monostearate palmitate. Also shellac, for example Shellac-KPS-Dreiring-SP (Kalkhoff GmbH) can be used according to the invention as a covering material.

The waxes, for example, are also included in the scope of the present invention so-called wax alcohols. Wax alcohols are higher molecular weight, water-insoluble fatty alcohols usually with about 22 to 40 carbon atoms. The Wax alcohols, for example, come in the form of wax esters of higher molecular weight Fatty acids (wax acids) as the main component of many natural waxes. examples for  Wax alcohols are lignoceryl alcohol (1-tetracosanol), cetyl alcohol, myristyl alcohol or Melissyl alcohol. The coating of the solid particles coated according to the invention can optionally also contain wool wax alcohols, including triterpenoid and Steroidal alcohols, for example lanolin, means that, for example, under the Trade name Argowax® (Pamentier & Co) is available. Also at least in part can be used as part of the envelope within the scope of the present invention Fatty acid glycerol esters or fatty acid alkanolamides, but optionally also water-insoluble ones or only slightly water-soluble polyalkylene glycol compounds.

Particularly preferred coating substances in the active substance which can be introduced into the cavity Punch particles are those from the group of polyethylene glycols (PEG) and / or poly propylene glycols (PPG) contains, with polyethylene glycols with molecular weights between 1500 and 36,000 preferred, those with molecular weights from 2000 to 6000 are particularly preferred and those with molecular weights of 3000 to 5000 are particularly preferred.

Here, active substance particles are particularly preferred which contain propylene glycols (PPG) and / or polyethylene glycols (PEG) as the only coating substance. According to the invention, a settable polypropylene glycol (PPG) are polymers of propylene glycol which have the general formula III

are sufficient, where n can take values between 10 and 2000. Preferred PPG show Molar masses between 1000 and 10,000, corresponding to values of n between 17 and approx. 170, on.

Polyethylene glycols (abbreviation PEG) which can preferably be used according to the invention are polymers of ethylene glycol which have the general formula IV

H- (O-CH ₂ -CH ₂ ) _n -OH (IV)

are sufficient, where n can have values between 20 and approx. 1000. The above ge Preferred molecular weight ranges mentioned correspond to preferred ranges Chen the value n in formula IV before about 30 to about 820 (exactly: from 34 to 818), especially preferably from about 40 to about 150 (exactly: from 45 to 136) and in particular from about 70 to approx. 120 (exactly: from 68 to 113).

The hull contained in the active substance particles according to the invention preferably contains Oil substance in the majority of paraffin wax. This means that at least 50% by weight of the total contained substances, preferably more, consist of paraffin wax. Paraffin wax contents (based on the total coating substance) of approximately are particularly suitable 60 wt .-%, about 70 wt .-% or about 80 wt .-%, with even higher proportions of for example, more than 90% by weight are particularly preferred. In a special one Embodiment of the invention consists of the total amount of the coating substance used made exclusively from paraffin wax.

Paraffin waxes have a frame compared to the other natural waxes mentioned The present invention has the advantage that in an alkaline Detergent environment no hydrolysis of the waxes takes place (as for example is to be expected in the wax esters), since paraffin wax has no hydrolyzable groups contains.

Paraffin waxes consist mainly of alkanes, as well as low levels of iso- and Cycloalkanes. The paraffin to be used according to the invention preferably has essentially no constituents with a melting point of more than 70 ° C., particularly preferably of more than 60 ° C. Shares of high-melting alkanes in the paraffin can fall below this melting temperature in the detergent fleet undesirable wax residues on the surfaces to be cleaned or the goods to be cleaned. Such Wax residues usually lead to an unsightly appearance of the cleaned Surface and should therefore be avoided.  

Particulate rinse aid which can preferably be introduced into the cavity contain as an envelope Substance at least one paraffin wax with a melting range of 50 ° C to 60 ° C.

The content of the paraffin wax used is preferably at ambient temperature (usually about 10 to about 30 ° C) solid alkanes, isoalkanes and cycloalkanes if possible high. The more solid wax components in a wax at room temperature, the more useful it is within the scope of the present invention. With increasing share of Solid wax components increase the resilience of the active substance particles Impacts or friction on other surfaces, resulting in longer-lasting protection of the Particle leads to active substances. High levels of oils or liquid wax components can lead to a weakening of the particles, which opens pores and the active substances be exposed to the environmental influences mentioned at the beginning.

In addition to paraffin as the main constituent, the coating substance can also have one or more of the above mentioned waxes or wax-like substances. Basically, that should be the Envelope forming mixture must be such that the active substance particles at least are largely insoluble in water. The solubility in water should be at a temperature of about 30 ° C do not exceed about 10 mg / l and are preferably below 5 mg / l.

In any case, however, the coating should have the lowest possible water solubility, also in Water with elevated temperature, have a temperature-independent release of the Avoid active substances as much as possible.

The principle described above serves to delay the release of ingredients a certain time in the cleaning cycle and can be Use dishwashing particularly advantageously if the main wash cycle is lower Temperature (for example 55 ° C) is rinsed so that the active ingredient from the Active substance particles are only released in the rinse cycle at higher temperatures (approx. 70 ° C) becomes.

Preferred particulate rinse aid that can be introduced into the cavity according to the invention are characterized in that they contain one or more substances with a  Melting range from 40 ° C to 75 ° C in amounts of 6 to 30 wt .-%, preferably from 7.5 to 25 wt .-% and in particular from 10 to 20 wt .-%, each based on the part weight, included. Detergent tablets are particularly preferred per, in which the particles contained in the cavity as paraffin (e) or Contain polyalkylene glycols, especially polyethylene glycols.

The active substance particles to be introduced into the cavity according to the invention Active substances contained can be processed at the processing temperature (i.e. at the temperature, in which the particles are produced) both in solid and in liquid form gene.

The active substances contained in the active substance particles fulfill certain tasks. Through the separation of certain substances or through the accelerated or Delayed release of additional substances can reduce cleaning performance be improved. Active substances that are preferably incorporated into the active substance particles That is why such ingredients of detergents and cleaning agents are decisive are involved in the washing or cleaning process.

In active substance particles to be incorporated preferably into the cavity (s) therefore one or more substances from the groups of surfactants, enzymes, Bleach, bleach activator, corrosion inhibitors, scale inhibitors, cobuilders and / or fragrances in amounts of 6 to 30% by weight, preferably 7.5 to 25% by weight and in particular from 10 to 20% by weight, in each case based on the particle weight hold. Methods in which those contained in the cavity are particularly preferred Active substance particles as active substances non-ionic surfactant (s) and / or bleach and / or bleach activators and / or enzyme (s) and / or corrosion inhibitors and / or Contain fragrances.

By incorporating surfactants into the melted shell material, one can Produce melt suspension or emulsion, which in the finished active substance particle or in the ready-made molded body according to the invention, to a predetermined Provides additional wash-active substance at the appropriate time. For example,  in this way active substance particles which can be incorporated into the cavity (s) produce machine dishwashing, the additional surfactant from the fiction, ge Only release moldings that are common household dishes at temperatures Only reach the dishwasher in the final rinse cycle. This way it is in the rinse aid cycle additional surfactant available, which accelerates the drainage of the water and so Stains on dishes are effectively prevented. With a suitable amount of solidified enamel suspension or emulsion in the active substance particles can thus on the use additional rinse aid, which is common today.

Is / are in active substance particles which can preferably be introduced into the cavity (s) therefore the active ingredient (s) selected from the group of nonionic surfactants, especially the alkoxylated alcohols. These substances have already been discussed in detail described.

Another class of active substances that are particularly advantageous in the inventions Bleaching agents that can be incorporated according to the invention are bleaching agents. Particles can be produced and introduced into the cavity (s), which only release the bleach when certain temperatures are reached, for example wise ready-made cleaning agents that clean enzymatically in the pre-rinse cycle and only release the bleach in the main wash cycle. Also are detergents for that machine dishwashing can be produced so that additional bleach in the rinse cycle are released and so difficult stains, such as tea stains, more effectively remove.

In particulate active substance which can preferably be incorporated into the cavity (s) Particles is / are therefore the active substance (s) selected from the group of the Sauer fabric or halogen bleach, especially chlorine bleach. This substance too zen have already been described in detail.

Another class of compounds that are preferred as active substances in the inventions Active substance particles which can be introduced according to the invention are the Bleach activators. The important representatives from this group of substances have already been  described. In the context of the present invention preferably in the / the cavity / - Particles introduced into the active substance contain bleach activators as the active substance, especially from the groups of polyacylated alkylenediamines, in particular Tetraacetylethylenediamine (TAED), the N-acylimide, especially N-nonanoylsuccinimide (NOSI), the acylated phenol sulfonates, especially n-nonanoyl- or isononanoyloxy benzenesulfonate (n- or iso-NOBS), n-methyl-morpholinium-acetonitrile-methyl sulfate (MMA).

Another important embodiment of the present invention provides for the introduction of enzyme-containing particles into the cavity (s). Such active substance particles contain as active substance (s) enzymes which have been described in detail above. Be particularly preferred here as particulate particles to be introduced into the cavity (s) are those containing 40 to 99.5% by weight, preferably 50 to 97.5% by weight, particularly preferably 60 to 95% by weight % and in particular 70 to 90% by weight of one or more coating substance (s) which have a melting point above 30 ° C., 0.5 to 60% by weight, preferably 1 to 40% by weight , particularly preferably 2.5 to 30% by weight and in particular 5 to 25% by weight of one or more liquid enzyme preparation (s) dispersed in the coating substance (s) and 0 to 20% by weight, preferably 0 up to 15% by weight, particularly preferably 0 to 10% by weight and in particular 0 to 5% by weight and optionally further carrier materials, auxiliaries and / or active ingredients. Preferred processes are accordingly characterized in that the cavity filling contains ne active substance comprising particles which

Fragrances can also be incorporated into the particles to be introduced as active substances All of the fragrances described in detail above can be active substance can be used. When fragrances are incorporated into the par Particles result in cleaning agents that delay all or part of the perfume release device. In this way, for example, cleaning agents for machine dishwashing can be produced, in which the consumer is also after Digter dishwashing experienced the perfume note when the machine was opened. In this way can cause the undesirable "alkaline smell" of many automatic dishwashing detergents is liable to be eliminated.  

Corrosion inhibitors can also be incorporated into the particles as an active ingredient, with the substances familiar to the expert can be used. As a base inhi For example, bitor has a combination of enzyme (e.g. lipase) and lime soaps proven dispersant.

At exceptionally low temperatures, for example at temperatures below 0 ° C, the active substance particle can break under impact or friction. To stability at such low temperatures can improve the coating substances if necessary Additives are added. Suitable additives must be completely with the Allow melted wax to mix, the melting range of the coating substances Do not change significantly, the elasticity of the sheathing at low temperatures improve the permeability of the casing to water or moisture generally do not increase and must not increase the viscosity of the melt of the shell material increase to the extent that processing becomes difficult or even impossible. Suitable Additives that reduce the brittleness of an envelope consisting essentially of paraffin Lowering at low temperatures are, for example, EVA copolymers, hydrogenated resin Acid methyl ester, polyethylene or copolymers of ethyl acrylate and 2-ethylhexyl acrylate.

Another useful additive when using paraffin as a coating is the addition of a small amount of a surfactant, for example a C _12-18 fatty alcohol sulfate. This addition results in a better wetting of the material to be embedded through the covering. It is advantageous to add the additive in an amount of about <5% by weight, preferably <about 2% by weight, based on the coating substance. The addition of an additive can in many cases lead to the fact that active substances can also be encased which, without the addition of an additive, generally form a tough, plastic body made of paraffin and partially dissolved active substance after the encapsulation material has melted.

It can also be advantageous to add further additives to the coating substance in order to to prevent early withdrawal of the active substances. This is particularly so in the production of the active substance particles according to the invention without carriers guess. The anti-settling agents that can be used for this purpose, also known as floating agents are from the prior art, for example from the lacquer and printing inks  manufacturing, known. To make the transition from the plastic solidification area to the festival Sedimentation phenomena and concentration gradient of the sub to be encased To avoid punching, there are, for example, surface-active substances in Lö dispersed waxes, montmorillonites, organically modified bentonites, (hy third) castor oil derivatives, soy lecithin, ethyl cellulose, low molecular weight polyamides, Me tall stearates, calcium soaps or hydrophobized silicas.

As materials of the type mentioned can also be found in cosmetic formulations widespread, some of these substances are classified in the INCI nomenclature (CTFA International Cosmetic Ingredient Dictionary and Handbook, ^5th Edition, The Cosmetic, Toiletry and Fragrance Association, Washington, 1997). This standard cosmetic work contains, for example, information on the keywords POLYGLYCERYL-3-BEESWAX, POLYGLYCERYL-3-CETYL ETHER, POLYGLYCERYL-4-COCOATE, POLYGLYCERYL-10-DECALINOLEATE, POLY GLYCERYL-10-DECAOLEYAR, POLYGLYCAR 2-DIISOSTEARATE, POLYGLYCERYL-3-DIISOSTEARATE, POLY GLYCERYL-10-DIISOSTEARATE, POLYGLYCERYL-2-DIOLEATE, POLY GLYCERYL-3-DIOLEATE, POLYGLYCERYL-6-DIOLEATE, POLYGLYCERYLYL-10- 6- DISTEARATE, POLYGLYCERYL-10-DISTEARATE, POLYGLYCERYL-10- HEPTAOLEATE, POLY-GYLCERYL-12-HYDROXYSTEARATE, POLYGLYCERYL- 10-HEPTASTEARATE, POLYGLYCERYL-6-HEXAOLEARATE-POLYGLYLATE-POLYGLYLATE POLY-GLYCERYL-6-ISOSTEARATE, POLY-GLYCERYL-10-LAURATE, POLY GLYCERYLMETHACRYLATE, POLYGLYCERYL-10-MYRISTATE, POLYGLYCERYL-2-OLEATE, POLYGLYCERYL-3-OLEATE, POLYGLYCERYL-POLYGLYCERYL-POLYGLYCERYL -8-OLEATE, POLYGLYCERYL-10-OLEATE, POLYGLYCERYL-6-PENTAOLEATE, POLYG LYCERYL-10-PENTAOLEATE, POLYGLYCERYL-6-PENTASTEARATE, POLYGLYCERYL-10-PENTASTEARATE, POLYGLYCERYL-2-SESQUI IOSOSTEARATE, POLYGLYCERYL-2-SESQUIOLEATE, POLYGLYARYATEURY-2-SESQUIOLEATE -8-STEARATE, POLYGLYCERYL-10-STEARATE, POLY GLYCERYL-2-TETRAISOSTEARATE, POLYGLYCERYL-10-TETRAOLEATE, POLYGLYCERYL-2-TETRASTEARATE, POLYGLYCERYL-2-TRIISOSTEARATE-POLYGLYL-TRY The commercially available products from different manufacturers, which are classified under the abovementioned keywords in the work mentioned, can advantageously be used as emulsifiers in process step b) according to the invention.

Another group of emulsifiers which can be used in the rinse aid or enzyme particles to be incorporated into the cavity (s) according to the invention are substituted silicones which carry side chains reacted with ethylene or propylene oxide. Such polyoxyalkylene siloxanes can be described by the general formula VI

in which each radical R ¹ independently of one another for -CH ₃ or a polyoxyethylene or propylene group - [CH (R ² ) -CH ₂ -O] _x H group, R ² for -H or -CH ₃ , x for a number between 1 and 100, preferably between 2 and 20 and in particular less than 10, and n indicates the degree of polymerization of the silicone.

Optionally, the polyoxyalkylenesiloxanes mentioned can also be attached to the free OH groups of the Polyoxyethylene or polyoxypropylene side chains are etherified or esterified. The Unetherified and unesterified polymer from dimethylsiloxane with polyoxyethylene and / or In the INCI nomenclature, polyoxypropylene is called DIMETHICONE COPOLYOL designated and is under the trade names Abil® B (Goldschmidt), Alkasil® (Rhône- Poulenc), Silwet® (Union Carbide) or Belsil® DMC 6031 commercially available.

The DIMETHICONE-COPOLYOL-ACETATE esterified with acetic acid (for example Belsil® DMC 6032, -33 and -35, Wacker) and the DIMETHICONE-COPOLYOL-BUTYL ETHERS (for example KF352A, Shin Etsu) are within the scope of the present invention can also be used as emulsifiers.

The same applies to the emulsifiers as to the wrapping materials and enveloping substances that they are used over a wide range can. Usually, emulsifiers of the type mentioned make up 1 to 25% by weight,  preferably 2 to 20% by weight and in particular 5 to 10% by weight of the weight of the Sum of wrapping materials and active substances. Within the scope of the present invention preferably particulate rinse aid to be introduced into the cavity (s) or Enzyme particles also contain emulsifiers from the group of fatty alcohols, Fatty acids, polyglycerol esters and / or polyoxyalkylene siloxanes in amounts of 0.1 to 5% by weight, preferably from 0.2 to 3.5% by weight, particularly preferably from 0.5 to 2% by weight % and in particular from 0.75 to 1.25% by weight, in each case based on the particle weight.

Regardless of how the particles in a preferred embodiment of the present ing invention can serve as a cavity filling, are composed, can these are attached to the molded body. This is particularly necessary if the cavity to be filled is not closed by (another) part b).

This fixation can be done by applying coating layers or spraying Lö solutions of binding materials, but it is also possible to use particles that are already dematerialien contain to soften superficially by heating, whereby adhesion comparable to sintering on the molded body is achieved. Of course it is also possible, before filling the cavity (s) with further active substance Punch or active substance preparation form adhesion promoter on the surfaces of the cavity to apply. Appropriate procedures in which the cavity is made with a mixture of Adhesion promoter (s) and active substance (s) are filled are preferred.

The coating layer optionally applied to the filling introduced into the cavity can applied to the surface of the cavity filling and adhesively bonded to it be what, for example by gluing, partial melting or by chemi reaction can take place.

The coating layer can of course also be a laminate of several different ones composite coating materials, over different compositions Individual coating layers can fill the cavity at certain times in the Washing and cleaning cycle are released.  

Preferred coating materials are the polymers known from the prior art. In particular, detergent tablets are preferred in which the Coa ting layer made of a polymer with a molecular weight between 5000 and 500,000 daltons, preferably between 7500 and 250,000 daltons and in particular between 10,000 and 100,000 daltons. With regard to the media, in the detergents and cleaning agents Detergent and cleaning agent form are usually introduced body preferred, in which the coating layer be made of a water-soluble polymer stands.

Such preferred polymers can be synthetic or natural in origin. If polymers on a native or part-native basis are used as coating material, then Detergent tablets are preferred, in which the coating material is made of is selected from one or more substances from the group carrageenan, guar, pectin, Xanthan, cellulose and its derivatives, starch and its derivatives and gelatin.

Carrageenan is an extract from North Atlantic red algae, which is one of the florid plants, and is named after the Irish coastal town of Carragheen. The carrageenan precipitated from the hot water extract of the algae is a colorless to sand-colored powder with molar masses of 100000-800000 and a sulfate content of approx. 25%, which is very easily soluble in warm water. There are three main components in carrageenan: The yellow-forming f fraction consists of D-galactose-4-sulfate and 3,6-anhydro-α-D-galactose, which are alternately glycosidically linked in the 1,3- and 1,4-positions are (in contrast, agar contains 3,6-anhydro-α-L-galactose). The non-gelling 1 fraction is composed of 1,3-glycosidically linked D-galactose-2-sulfate and 1,4-linked D-galactose-2,6-disulfate residues and is easily soluble in cold water. The i-carrageenan composed of D-galactose-4-sulfate in 1,3-bond and 3,6-anhydro-aD-galactose-2-sulfate in 1,4-bond is both water-soluble and gel-forming. Other types of carrageenan are also designated with Greek letters: α, β, γ, µ, ν, ξ, π, ω, χ. The type of cations present (K, NH ₄ , Na, Mg, Ca) also influences the solubility of the carrageenans. Semi-synthetic products that contain only one type of ion and can also be used as coating materials in the context of the present invention are also called carrag (h) eenate.

The guar which can be used as coating material in the context of the present invention, too Called guar flour, is an off-white powder that is obtained by grinding the endosperm of the ur originally endemic in the Indian and Pakistani regions, now also in others ren countries, e.g. B. cultivated in the south of the USA, belong to the legume family guar bean (Cyamopsis tetragonobolus) is obtained. The main ingredient of the guar is with up to approx. 85% by weight of the dry substance guaran (guar gum, cyamopsis Rubber); Minor components are proteins, lipids and cellulose. Guaran itself is a bum lygalactomannan, d. H. a polysaccharide, the linear chain of which is unsubstituted (see Formula VII) and substituted in the C6 position with a galactose residue (see formula (VIII) Mannose units in β-D (1 → 4) linkage is built.

The ratio of VII: VIII is approximately 2: 1; Contrary to original assumptions, the VIII units are not strictly alternating, but are arranged in pairs or triplets in the polygalac tomannan molecule. Information on the molar mass of guaran varies with values of approx.2.2. 10 ⁵ -2.2. 10 ⁶ g / mol depending on the degree of purity of the polysaccharide - the high value was determined on a highly purified product - significantly and correspond to approx. 1350-13500 sugar units / macromolecule. Guaran is insoluble in most organic solvents.

The pectins, which can also be used as coating material, are high molecular weight glycosidic Plant substances that are very common in fruits, roots and leaves. The pectins  consist essentially of chains of 1,4-α-glycoside. associated galacturonic acid Units whose acid groups are esterified to 20-80% with methanol, one between high-esterified (<50%) and low-esterified pectins (<50%). The Pectins have a sheet structure and are therefore in the middle of starch and cellulose Molecules. Your macromolecules still contain some glucose, galactose, xylose and Arabinose and have slightly acidic properties.

Fruit pectin contains 95%, beet pectin up to 85% galacturonic acid. The molecular weights of the ver Different pectins vary between 10,000 and 500,000. The structural properties also are strongly dependent on the degree of polymerization; so form z. B. the fruit pectins in dry Asbestos-like fibers, while the flax pectins, on the other hand, are fine, granular powders.

The pectins are mainly extracted from the inside by extraction with dilute acids Portions of citrus fruit peel, leftovers or beet pulp.

Xanthan can also be used as a coating material according to the invention. Xanthan is a microbial anionic heteropolysaccharide that is produced by Xanthomonas campestris and some other species under aerobic conditions and has a molecular weight of 2 to 15 million Daltons. Xanthan is formed from a chain with β-1,4-bound glucose (cellulose) with side chains. The structure of the subgroups consists of glucose, mannose, glucuronic acid, acetate and pyruvate, the number of pyruvate units determining the viscosity of the xanthan. Xanthan can be described by the following formula:

The celluloses and their derivatives are also suitable as coating materials. Pure cellulose has the formal gross composition (C ₆ H ₁₀ O ₅ ) _n and, formally considered, is a β-1,4-polyacetal of cellobiose, which in turn is made up of two molecules of glucose. Suitable celluloses consist of approximately 500 to 5000 glucose units and consequently have average molecular weights of 50,000 to 500,000. As a coating material based on cellulose can be used in the context of the present invention, cellulose derivatives, which are obtainable by polymer-analogous reactions from cellulose. Such chemically modified celluloses include, for example, products from esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. However, celluloses in which the hydroxyl groups have been replaced by functional groups which are not bound by an oxygen atom can also be used as cellulose derivatives. The group of cellulose derivatives includes, for example, alkali celluloses, carboxymethyl cellulose (CMC), cellulose esters and ethers and aminocelluloses.

In addition to cellulose and cellulose derivatives, (modified) dextrins, starch and Starch derivatives are used as coating materials.

Dextrins, for example, are suitable as nonionic organic coating materials Oligomers or polymers of carbohydrates by partial hydrolysis of starches can be obtained. The hydrolysis can be carried out according to conventional methods, for example acid or enzyme-catalyzed processes are carried out. It is preferably Hy Drolysis products with average molecular weights in the range of 400 to 500000 g / mol. It is a polysaccharide with a dextrose equivalent (DE) in the range from 0.5 to 40, in particular special from 2 to 30 preferred, DE being a customary measure of the reducing Effect of a polysaccharide compared to dextrose, which has a DE of 100, is. Both maltodextrins with a DE between 3 and 20 and dry can be used glucose syrups with a DE between 20 and 37 as well as so-called yellow dextrins and White dextrins with higher molar masses in the range from 2000 to 30000 g / mol.

The oxidized derivatives of such dextrins are their reaction products with oxidizing agents which are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. A product oxidized at C _{6 of} the saccharide ring can be particularly advantageous.

Starch can also be used as a coating material for the washing and cleaning agents according to the invention moldings are used. Starch is a homoglycan, with the glucose Units are linked α-glycosidically. Starch is made up of two components Chen molecular weight built: From approx. 20-30% straight-chain amylose (MW. approx. 50,000-150,000) and 70-80% branched chain amylopectin (MW. Approx. 300,000- 2,000,000), as well as small amounts of lipids, phosphoric acid and cations contain. While the amylose is long due to the 1,4-position binding, forms helical, intertwined chains with about 300-1200 glucose molecules, In the case of amylopectin, the chain branches out after an average of 25 glucose units by 1,6-binding to a knot-like structure with about 1500-12000 molecules Glucose. In addition to pure starch, coating materials are within the scope of the present Invention also uses starch derivatives derived from starch by polymer-analogous reactions are available. Such chemically modified starches include  chemically modified starches include, for example, products from vereste stungen or etherifications in which hydroxy hydrogen atoms have been substituted. But also strengths in which the hydroxy groups against functional groups that are not are bound via an oxygen atom, can be replaced as starch derivatives deploy. The group of starch derivatives includes, for example, alkali starches, car boxymethyl starch (CMS), starch esters and ethers and amino starches.

Gelatin has one of the proteins and modified proteins as a coating material outstanding importance. Gelatin is a polypeptide (molecular weight: approx.15,000- <250,000 g / mol), mainly by hydrolysis of the skin and bones of animals contained collagen is obtained under acidic or alkaline conditions. The Amino acid composition of gelatin largely corresponds to that of collagen, from which it was obtained and varies depending on its provenance. The Use of gelatin as a water-soluble coating material is particularly in the Pharmaceuticals in the form of hard or soft gelatin capsules are extremely widespread.

Other polymers which can be used as coating materials are synthetic polymers which are preferably water-swellable and / or water-soluble. Such synthetic-based polymers can be "tailor-made" for the desired coating permeability during storage and dissolution of the coating layer when used. Particularly preferred detergent tablets according to the invention are characterized in that the coating material is selected from a polymer or polymer mixture, the polymer or at least 50% by weight of the polymer mixture being selected from

The laundry detergent and cleaning product tablets according to the invention can be packaged after manufacture, the use of certain packaging systems having proven particularly effective. Another aspect of the present invention is a combination of (a) detergent tablets according to the invention and a packaging system containing the detergent tablets, characterized in that the packaging system has a moisture vapor permeability rate of 0.1 g / m ² / Day to less than 20 g / m ² / day if the packaging system is stored at 23 ° C and a relative equilibrium humidity of 85%.

The packaging system of the combination of detergent tablets and packaging system according to the invention has a moisture vapor permeability rate of 0.1 g / m ² / day to less than 20 g / m ² / day when the packaging system is at 23 ° C. and a relative equilibrium humidity of 85% is stored. The named temperature and humidity conditions are the test conditions that are mentioned in the DIN standard 53122, whereby according to DIN 53122 minimal deviations are permitted (23 ± 1 ° C, 85 ± 2% relative humidity). The moisture vapor permeability rate of a given packaging system or material can be determined by further standard methods and is, for example, also in the ASTM standard E-96-53T ("Test for measuring Water Vapor transmission of Materials in Sheet form") and in the TAPPI standard T464 m- 45 ("Water Vapor Permeability of Sheet Materials at high temperature and Humidity"). The measuring principle of current methods is based on the water absorption of anhydrous calcium chloride, which is stored in a container in the appropriate atmosphere, the container being closed at the top with the material to be tested. From the surface of the container, which is closed with the material to be tested (permeation surface), the increase in weight of calcium chloride and the exposure time, the moisture vapor transmission rate can be determined

calculate, where A is the area of the material to be tested in cm ² , x is the weight gain of calcium chloride in g and y is the exposure time in h.

The relative equilibrium humidity, often referred to as "relative humidity", is 85% at 23 ° C. when measuring the moisture vapor transmission rate within the scope of the present invention. The absorption capacity of air for water vapor increases with temperature up to a respective maximum content, the so-called saturation content, and is given in g / m ³ . For example, 1 m ^{3 of} air at 17 ° is saturated with 14.4 g of water vapor; at a temperature of 11 ° there is already saturation with 10 g of water vapor. The relative humidity is the ratio of the actual water vapor content to the saturation content corresponding to the prevailing temperature. For example, if air contains 17 ° 12 g / m ³ water vapor, then the relative humidity = (12 / 14.4). 100 = 83%. If you cool this air, then the saturation (100% r.L.) is reached at the so-called dew point (in the example: 14 °), ie, if it cools further, a precipitate is formed in the form of mist (dew). Hygrometers and psy chrometers are used for the quantitative determination of moisture.

The relative equilibrium humidity of 85% at 23 ° C can be found, for example, in La Borehouses with moisture control to +/- 2% r. Adjust L. exactly. Even over saturated solutions of certain salts form in closed systems constant and well-defined relative humidity at a given temperature, that on the phase equilibrium between partial pressure of water, saturated solution and soil body are based.

Although it is possible, wax-coated in addition to the films or papers mentioned Papers in the form of cardboard boxes as a packaging system for washing and cleaning to use medium shaped bodies, it is preferred in the context of the present invention if the packaging system does not include boxes made of wax-coated paper. The The term “packaging system” in the context of the present invention always the primary packaging of the moldings, d. H. the packaging that is on the inside is in direct contact with the molded body surface. To an optional secondary pack No requirements are made, so that all common materials and Systems can be used.

Regardless of the ver application of the shaped body, it is preferred according to the invention that the or Detergent tablets have a relative equilibrium moisture content of less than 30% at 35 ° C.

The relative equilibrium moisture content of the detergent tablets can are determined according to common methods, whereby within the scope of the present The following procedure was chosen for investigations: Liter jar with a lid, which has a closable opening for insertion of samples, was washed with a total of 300 g of detergent tablets filled with pern and kept at a constant 23 ° C for 24 h in order to maintain a constant temperature of  Ensure vessel and substance. The water vapor pressure in the room over the form can then use a hygrometer (Hygrotest 6100, Testoterm Ltd., England) be true. The water vapor pressure is now measured every 10 minutes until two successive values show no deviation (equilibrium moisture). The above Hygrometer allows a direct display of the recorded values in percent relative humidity action.
