Description

 Multi-phase detergent or cleaner tablet

The present invention is in the field of detergents or cleaners. In particular, the present invention relates to multiphase detergent tablets.

Detergents or cleaners are now available to the consumer in a variety of forms. In addition to washing powders and granules, this offer also includes, for example, detergent concentrates in the form of extruded or tabletted compositions. These fixed, concentrated or compressed forms of supply are characterized by a reduced volume per dosing unit and thus reduce the costs for packaging and transport. In particular, the washing or cleaning agent tablets additionally meet the consumer's desire for simple dosing. The corresponding means are comprehensively described in the prior art. However, in addition to the advantages listed, compacted detergents or cleaners also have a number of disadvantages. Especially tableted supply forms are characterized by their high compression often by a delayed disintegration and thus a delayed release of their ingredients. To solve this "conflict" between sufficient tablet hardness and short disintegration times, numerous technical solutions have been disclosed in the patent literature, reference being made to the use of so-called tablet disintegrants by way of example Although they themselves generally do not have any washing or cleaning-active properties, in this way they increase the complexity and the costs of these agents Active substances due to the compaction pressure occurring during tabletting Inactivation of the active substances may also be due to the increased contact surfaces of the ingredients due to chemical reaction e rfolgen.

As an alternative to the particulate or compacted detergents or cleaners described above, solid or liquid detergents or cleaners which have a water-soluble or water-dispersible packaging are increasingly being described in recent years. These agents are characterized as the tablets by a simplified dosage, since they can be dosed together with the outer packaging in the washing machine or dishwasher, but on the other hand they also allow the preparation of liquid or powdered detergents or cleaners, which are compared to Kompak - did characterized by a better resolution and faster effectiveness. For example, EP 1 314 654 A2 (Unilever) discloses a dome-shaped pouch with a receiving chamber containing a liquid.

The subject of WO 01/83657 A2 (Procter & Gamble), however, are pouches which contain two particulate solids in a receiving chamber, each of which is present in fixed regions and does not mix with one another.

In addition to the packages which have only one receiving chamber, the prior art has also disclosed forms of offers which comprise more than one receiving chamber or more than one ready-made form.

Subject of the European application EP 1 256 623 A1 (Procter & Gamble) is a kit of at least two bags with different composition and optics. The bags are separate and not as a compact single product.

A method for producing multi-chamber bags by bonding second individual chambers describes the international application WO 02/85736 A1 (Reckitt Benckiser).

The object of the present application was to provide a process for the preparation of detergents or cleaners, which enables the joint preparation of solid and liquid or flowable detergent or cleaner compositions in separate areas of a compact dosing unit. The final process product should be characterized by an attractive appearance.

It has now been found that the abovementioned objects can be achieved by a method in which a washing or cleaning-active shaped body with two cavities is provided, these cavities being filled with washing- or cleaning-active compositions.

A first subject of the present application is therefore a washing or cleaning agent molding having at least two cavities in the form of through holes, characterized in that at least two of these cavities are filled with washing or cleaning active compositions and the composition in one of the cavities of the composition in different from another cavity.

The subject of the present application is a detergent or cleaner tablet. Such moldings are obtainable, for example, by compaction methods such as tableting, by extrusion, such as extrudate extrusion, by injection molding or by casting. special In the context of the present application, moldings which are produced by tabletting or by casting are preferred. The moldings contain or consist of washing or cleaning-active substances or substance mixtures. Detergent or detergent tablets, characterized in that the tablet is a compacted, preferably tableted, extruded or cast tablet, are preferred according to the invention.

The preparation of washing or cleaning agent tablets is carried out in a manner known to those skilled in the art by compressing particulate starting substances. To produce the tablets, the premix is compacted in a so-called matrix between two punches to form a solid compress. This process, hereinafter referred to as tabletting, is divided into four sections: dosing, compaction (elastic deformation), plastic deformation and ejection. The tabletting is preferably carried out on so-called rotary presses.

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

Use of plastic inserts with small thickness tolerances Low number of revolutions of the rotor - Large filling shoes

Matching the filling paddle speed to the speed of the rotor Discharge shoe with constant powder level Decoupling of filling shoe and powder feed

To reduce Stempelanbackungen offer all known from the art non-stick coatings. Plastic coatings, plastic inserts or plastic stamps are particularly advantageous. Rotary punches have also proved to be advantageous, wherein, if possible, upper and lower punches should be rotatable. With rotating punches can be dispensed with a plastic insert usually. Here, the stamp surfaces should be electropolished.

In the context of the present invention, preferred methods are characterized in that the pressing takes place at pressing pressures of 0.01 to 50 kNcnϊ ² , preferably of 0.1 to 40 kNcm ^"2 and in particular of 1 to 25 kNcm ^{" 2} . The production of preferred casting bodies according to the invention is carried out, for example, by casting a washing or cleaning-active preparation into a mold and subsequently demolding the solidified cast body to form a (mold) shaped body. Tools which have cavities which can be filled with pourable substances are preferably used as "molds." Such tools can be designed, for example, in the form of individual cavities or also in the form of plates having a plurality of cavities mounted horizontally circulating conveyor belts, which allow a continuous or discontinuous transport of the cavities, for example, along a number of different workstations (eg: casting, cooling, filling, sealing, demolding, etc.).

The detergent tablets are preferably molded tablets which are obtained by pouring washing- or cleaning-active preparations into them, the formulations subsequently solidifying to form a dimensionally stable body. In the context of the present invention, "solidification" characterizes any curing mechanism which delivers a body which is solid at room temperature from a deformable, preferably flowable mixture or substance or mass, without the need for pressing or compacting forces The purpose of the present invention is therefore, for example, the curing of melts of solid substances at room temperature by cooling. "Solidification processes" in the context of the present application are also the curing of formable materials by time-delayed water binding, by evaporation of solvents, by chemical reaction, crystallization, etc. and the reactive curing of flowable powder mixtures to form stable hollow bodies.

In a preferred Embodiment, the film material comprises one or more water-soluble (s) polymers), preferably a material from the group (optionally acetalized) polyvinyl alcohol (PVAL), polyvinylpyrrolidone, polyethylene oxide, gelatin, cellulose, and derivatives thereof and mixtures thereof used.

"Polyvinyl alcohols" (abbreviated PVAL, occasionally PVOH) is the name for polymers of the general structure

CH 2 CH CH 2 CH OH OH

in small proportions (about 2%) also structural units of the type

CH 2 CH CH CH 2 OH OH

contain.

Commercially available polyvinyl alcohols, which are available as white-yellowish powders or granules with degrees of polymerization in the range of about 100 to 2500 (molar masses of about 4000 to 100,000 g / mol), have degrees of hydrolysis of 98-99 or 87-89 mol%. , so still contain a residual content of acetyl groups. The polyvinyl alcohols are characterized by the manufacturer by indicating the degree of polymerization of the starting polymer, the degree of hydrolysis, the saponification number or the solution viscosity.

Depending on the degree of hydrolysis, polyvinyl alcohols are soluble in water and a few highly polar organic solvents (formamide, dimethylformamide, dimethyl sulfoxide); They are not attacked by (chlorinated) hydrocarbons, esters, fats and oils. Polyvinyl alcohols are classified as toxicologically safe and are biologically at least partially degradable. The water solubility can be reduced by aftertreatment with aldehydes (acetalization), by complexation with Ni or Cu salts or by treatment with dichromates, boric acid or borax. The coatings of polyvinyl alcohol are largely impermeable to gases such as oxygen, nitrogen, helium, hydrogen, carbon dioxide, but allow water vapor to pass through. In the present invention, it is preferred that the sheet material used at least partially comprises a polyvinyl alcohol whose degree of hydrolysis 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol%, and especially 82 to 88 mol -% is. In a preferred embodiment, the first film material used in the process according to the invention comprises at least 20% by weight, more preferably at least 40% by weight, very preferably at least 60% by weight and in particular at least 80% by weight. of a polyvinyl alcohol whose degree of hydrolysis is 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol%, and more preferably 82 to 88 mol%.

Polyvinyl alcohols of a certain molecular weight range are preferably used as the film material, it being preferred according to the invention that the film material comprises a polyvinyl alcohol whose molecular weight is in the range of 10,000 to 100,000 gmol ^-1 , preferably 11,000 to 90,000 gmol ^-1 , particularly preferably 12,000 to 80,000 gmol ^'1 and in particular from 13,000 to 70,000 gmol ^{' 1} .

The degree of polymerization of such preferred polyvinyl alcohols is between about 200 to about 2100, preferably between about 220 to about 1890, more preferably between about 240 to about 1680, and most preferably between about 260 to about 1500.

The polyvinyl alcohols described above are widely available commercially, for example under the trade name Mowiol ^® (Clariant). In the present invention, particularly suitable polyvinyl alcohols are, for example, Mowiol ^® 3-83, Mowiol ^® 4-88, Mowiol ^® 5-88 and Mowiol ^® 8-88.

Further polyvinyl alcohols which are particularly suitable as film material are shown in the following table:

Other suitable polyvinyl alcohols are as the film material ^® ELVANOL 51-05, 52-22, 50-42, 85- 82, 75-15, T-25, T-66, 90-50 (trademark of Du Pont), ALCOTEX 72.5 ^®, 78, B72, F80 / 40, F88 / 4, F88 / 26, F88 / 40, F88 / 47 (trademark of Harlow Chemical Co.), Gohsenol ^® NK-05, A-300, AH-22, C-500, GH-20, GL-03, GM-14L, KA-20, KA-500, KH-20, KP-06, N-300, NH-26, NM11Q, KZ-06 (Trademark of Nippon Gohsei KK).

The water solubility of PVAL can be altered by post-treatment with aldehydes (acetalization) or ketones (ketalization). Polyvinyl alcohols which are acetalated or ketalized with the aldehyde or keto groups of saccharides or polysaccharides or mixtures thereof have proven to be particularly advantageous and particularly advantageous on account of their pronounced cold water solubility. To use extremely advantageous are the reaction products of PVAL and starch.

Furthermore, the water solubility can be changed by complexing with Ni or Cu salts or by treatment with dichromates, boric acid, borax and thus set specifically to desired values. Films made of PVAL are largely impermeable to gases such as oxygen, nitrogen, helium, hydrogen, carbon dioxide, but allow water vapor to pass through.

Examples of suitable water PVAL films are those available under the name "SOLUBLON® ^®" from Syntana Handelsgesellschaft E. Harke GmbH & Co. PVAL films. Their solubility in water can be adjusted to the exact degree, and films of this product series are available which are soluble in aqueous phase in all temperature ranges relevant for the application.

Polyvinylpyrrolidones, referred to as PVP for short, can be described by the following general formula:

PVP are prepared by radical polymerization of 1-vinylpyrrolidone. Commercially available PVP have molecular weights in the range of about 2,500 to 750,000 g / mol and are available as white, hygroscopic powders or as aqueous solutions.

They have molar masses in the range of about 200 to 5,000,000 g / mol, corresponding to degrees of polymerization n of about 5 to> 100,000. Polyethylene oxides have an extremely low concentration of reactive hydroxy end groups and show only weak glycol properties.

Gelatin is a polypeptide (molecular weight: about 15,000 to> 250,000 g / mol), which is obtained primarily by hydrolysis of the collagen contained in the skin and bones of animals under acidic or alkaline conditions. The amino acid composition of gelatin is broadly similar to that of the collagen from which it was obtained and varies depending on its provenance.

Also preferred are film materials which comprise a polymer from the group starch and starch derivatives, cellulose and cellulose derivatives, in particular methyl cellulose and mixtures thereof.

Starch is a homoglycan, wherein the glucose units are linked α-glycosidically. Starch is composed of two components of different molecular weights: about 20 to 30% straight-chain amylose (MW about 50,000 to 150,000) and 70 to 80% branched-chain amylopectin (MW about 300,000 to 2,000,000). In addition, small amounts of lipids, phosphoric acid and cations are still included. Whereas the amylose forms long, helical, entangled chains with approximately 300 to 1,200 glucose molecules as a result of the 1, 4-position bond, the amylopectin branch branches off into a branch-like structure after an average of 25 glucose building blocks by 1,6-bonding with about 1,500 to 12,000 molecules of glucose. In addition to pure starch, starch-derivatives which are obtainable from starch by polymer-analogous reactions are also suitable for the preparation of water-soluble coatings of the detergent, detergent and cleaner portions in the context of the present invention. Such chemically modified starches include, for example, products of esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. However, starches in which the hydroxy groups have been replaced by functional groups that are not bound by an oxygen atom can also be used as starch derivatives. The group of starch derivatives includes, for example, alkali starches, carboxymethyl starch (CMS), starch esters and ethers and amino starches.

Suitable celluloses consist of about 500 to 5,000 glucose units and therefore have average molecular weights of 50,000 to 500,000. Cellulose-based disintegrating agents which can be used in the context of the present invention are also cellulose derivatives obtainable by polymer-analogous reactions of cellulose. Such chemically modified celluloses include, for example, products from esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. Celluloses in which the hydroxy groups have been replaced by functional groups which are not bonded via an oxygen atom can also be used as cellulose derivatives. The group of cellulose derivatives includes, for example, alkali metal celluloses, carboxymethyl cellulose (CMC), cellulose esters and ethers, and aminocelluloses.

Preference is therefore given, for example, to processes for producing a portioned detergent or cleaner, comprising the steps of a) deep-drawing a water-soluble or water-soluble film to form a water-soluble or water-dispersible receiving chamber and inserting a washing or cleaning agent shaped body having at least two cavities in the form of through holes in them receiving chamber; b) filling one of the cavities with a first washing or cleaning active composition; c) filling a further cavity with a second washing or cleaning active composition; d) Optional application of a sealing element.

Particularly preferred method variants are characterized in that the shaped body has two cavities in the form of through holes, each of these cavities having two openings which are located on opposite sides of the shaped body. Particularly preferred are those process variants using deep-drawn water-soluble or water-dispersible receiving chambers in which two of the four openings of the previously described shaped body are closed by the water-soluble or water-dispersible sheet material of a deep-drawn receptacle, while the two remaining openings through a sealing element, preferably a water-soluble or water-dispersible film to be closed.

Preference is therefore also given, for example, to processes for producing a portioned washing or cleaning agent, comprising the steps of a) providing a washing or cleaning agent shaped body having at least two cavities in the form of through holes; b) deep-drawing a water-soluble or water-soluble film into at least one of the cavities to form a receiving chamber surrounded by a water-soluble or water-dispersible film in the cavity; c) filling one of the cavities with a first washing or cleaning active composition; d) filling a further cavity with a second washing or cleaning active composition; e) Optional application of a sealing element on the remaining openings of the cavities.

In an alternative embodiment to the method described above, the water-soluble film is not deep-drawn into a receiving chamber into which the shaped body is inserted, whereby the shaped body is at least partially surrounded by this thermoformed receiving chamber, but it is the water-soluble or water-dispersible film rather in the cavities the molded body deep-drawn, whereby the inner walls of the cavities are lined with the film and in this way a direct contact between the ingredients of the shaped body and the ingredients of Kavitätenfüllungen is avoided. Preferred processes according to the invention therefore comprise the steps of a) deep-drawing a water-soluble or water-soluble film to form a water-soluble or water-dispersible receiving chamber and inserting a washing or cleaning agent shaped article having two cavities in the form of through holes, each of the cavities having two openings, each facing on opposite sides Sides of the shaped body are, in such a way in this receiving chamber, that in each case one of the openings of each cavity is closed by the film material of the deep-drawn water-soluble or water-dispersible receiving chamber; b) filling one of the cavities with a first washing or cleaning active composition; c) filling a further cavity with a second washing or cleaning active composition; d) Optional application of a sealing element on the remaining openings of the cavities.

Of course, the sealing material which closes the openings of the cavities does not necessarily have to be a deep-drawn receiving chamber. Alternatively, the openings of the cavities can also be closed by simple sealing elements of the type described above.

These and other preferred ingredients will be described in more detail below.

builders

The builders include, in particular, the zeolites, silicates, carbonates, organic cobuilders and, where there are no ecological prejudices against their use, also the phosphates.

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. Also suitable, however, are zeolite X and mixtures of A, X and / or P. Commercially available and preferably usable in the context of the present invention is, for example, a cocrystal of zeolite X and zeolite A (about 80% by weight of zeolite X) ), which is sold by the company 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 granular compound and for a kind of "powdering" of a granular mixture, preferably a mixture to be compressed, whereby usually both ways of incorporating the zeolite into the premix are used an average particle size of less than 10 μm (volume distribution, measuring method: Coulter Counter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight, of bound water.

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 O to 20, and preferred values for x 2, 3 or 4 are. Preferred crystalline layered silicates of the formula given are those in which M is sodium and x assumes the values 2 or 3. In particular, both β- and δ-sodium disilicates Na ₂ Si ₂ O ₅ ^.yH ₂ O are preferred.

With particular preference, in particular as a constituent of machine dishwashing detergents, crystalline layered silicates of general formula NaMSi _x O _{2x + 1} ^• y H ₂ O are used, wherein M is sodium or hydrogen, x is a number from 1, 9 to 22, preferably from 1 , 9 to 4, and y is a number from 0 to 33. The crystalline layered silicates of the formula NaMSi _x O _{2x + 1} ^• y H ₂ O are sold, for example, by the company Clariant GmbH (Germany) under the trade name Na-SKS. Examples of these silicates are Na-SKS-1 (Na ₂ Si ₂₂ O ₄₅ ^■ x H ₂ O, Ken yait), Na-SKS-2 (Na ₂ Si ₁₄ O ₂₉ ^• x H ₂ O, magadiite), Na-SKS-3 (Na ₂ Si ₈ O ₁₇ ^• x H ₂ O) or Na-SKS-4 (Na ₂ Si ₄ O ₉ ^• x H ₂ O, Makatite).

For the purposes of the present invention crystalline layer silicates are particularly suitable of the formula NaMSi _x O _{2x + 1} ^• y H ₂ O, in which x stands for 2 h. Of these, especially Na-SKS-5 ((X-Na ₂ Si ₂ O ₅ ), Na-SKS-7 (B-Na ₂ Si ₂ O ₅ , natrosilite), Na-SKS-9 (NaHSi ₂ O ₅ ^■ H ₂ O), Na-SKS-10 (NaH Si ₂ O ₅ ^■ 3 H ₂ O, kanemite), Na-SKS-11 (t-Na ₂ Si ₂ 0 ₅₎ and Na-SKS-13 ( NaHSi ₂ O ₅ ), but especially Na-SKS-6 (5-Na ₂ Si ₂ O ₅ ).

When the silicates are used as part of automatic dishwashing agents, these compositions preferably comprise a proportion by weight of the crystalline layered silicate of the formula NaMSi _x O _{2x + 1} ^• y H ₂ O from 0.1 to 20 wt .-%, from 0.2 to 15 wt .-% and in particular from 0.4 to 10 wt .-%, each based on the total weight of these agents. It is particularly preferred in particular if such automatic dishwashing agents have a total silicate content of less than 7% by weight, preferably less than 6% by weight, preferably less than 5% by weight, more preferably less than 4% by weight, most preferably less than 3% by weight % and in particular below 2.5 wt .-%, wherein it is in this silicate, based on the total weight of the silicate contained, preferably at least 70 wt .-%, preferably at least 80 wt .-% and in particular to At least 90 wt .-% of silicate of the general formula NaMSi- χθ _{2x +} i ^■ y H ₂ O is.

It is also possible to use amorphous sodium silicates with a Na ₂ O: SiO ₂ modulus of from 1: 2 to 1: 3.3, preferably from 1: 2 to 1: 2.8 and in particular from 1: 2 to 1: 2.6, which Delayed and have secondary washing properties. The dissolution delay compared with conventional amorphous sodium silicates may have been caused in various ways, for example by surface treatment, compounding, compaction / densification 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 do not yield sharp X-ray reflections typical of crystalline substances in X-ray diffraction experiments, but at most one or more maxima of the scattered X-rays which have a width of several degrees of diffraction angle. However, it may well even lead to particularly good builder properties if the silicate particles provide blurred or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline regions of the size of ten to a few hundred nm, with values of up to max. 50 nm and in particular up to max. 20 nm are preferred. Such so-called X-ray amorphous silicates also have a dissolution delay compared with the conventional water glasses. Particularly preferred are compacted / compacted amorphous silicates, compounded amorphous silicates and overdried X-ray amorphous silicates. In the context of the present invention, it is preferred that these silicate (s), preferably alkali silicates, particularly preferably crystalline or amorphous Alkalidisilikate, in detergents or cleaners in amounts of 10 to 60 wt .-%, preferably from 15 to 50 Wt .-% and in particular from 20 to 40 wt .-%, each based on the weight of the washing or cleaning agent, are included.

Of course, a use of the well-known phosphates as builders is possible, unless such use should not be avoided for environmental reasons. This applies in particular to the use of compositions according to the invention or agents prepared by the process according to the invention as automatic dishwasher detergents, which is particularly preferred in the context of the present application. Among the large number of commercially available phosphates, the alkali metal phosphates, with particular preference for pentasodium or pentapotassium triphosphate (sodium or potassium tripolyphosphate), are of greatest importance in the washing and cleaning agent industry.

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

Suitable phosphates are for example the sodium dihydrogen phosphate, NaH ₂ PO ₄ , in the form of the dihydrate (density 1, 91 like ^'3 , melting point 60 °) or in the form of monohydrate (density 2.04 like ^"3 ), the disodium hydrogen phosphate (secondary sodium phosphate) , Na ₂ HPO ₄ , which is anhydrous or with 2 mol (density 2.066 like ^"3 , water loss at 95 °), 7 mol (density 1, 68 like ^'3 , melting point 48 ° with loss of 5 H ₂ O) and 12 mol Water (density 1, 52 like ^'3 , melting point 35 ° with loss of 5 H ₂ O) can be used, but especially the trisodium phosphate (tertiary sodium phosphate) Na ₃ PO ₄ , which as dodecahydrate, as decahydrate (corresponding to 19-20% P ₂ O ₅ ) and in anhydrous form (corresponding to 39-40% P ₂ O ₅ ) can be used.

Another preferred phosphate is the tripotassium phosphate (tertiary or tribasic potassium phosphate), K ₃ PO ₄ . Also preferred are the tetrasodium diphosphate (sodium pyrophosphate), Na ₄ P ₂ O ₇ , which is in anhydrous form (density 2.534 like ^'3 , melting point 988 °, also indicated 880 °) and as decahydrate (density 1, 815-1, 836 like ^"3 , melting point 94 ° with loss of water), as well as the corresponding potassium salt potassium diphosphate (potassium pyrophosphate), K ₄ P ₂ O ₇ . The technically important pentasodium triphosphate, Na ₅ P ₃ O ₁₀ (sodium tripolyphosphate), is an anhydrous or with 6 H ₂ O crystallizing, non-hygroscopic, colorless, water-soluble salt of the general formula NaO- [P (O) (ONa) -O] _n -Na with n = 3. The corresponding potassium salt pentapotassium triphosphate, K ₅ P ₃ Oi ₀ (potassium tripolyphosphate), for example, in the form of a 50 wt .-% solution (> 23% P ₂ O ₅ , 25% K ₂ O) in the trade. The potassium polyphosphates are widely used in the washing and cleaning industry. There are also sodium potassium tripolyphosphates which can likewise be used in the context of the present invention. These arise, for example, when hydrolyzed sodium trimetaphosphate with KOH:

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

These are used according to the invention exactly as sodium tripolyphosphate, potassium tripolyphosphate or mixtures of these two; Mixtures of sodium tripolyphosphate and sodium potassium tripolyphosphate or mixtures of potassium tripolyphosphate and sodium potassium tripolyphosphate or mixtures of sodium tripolyphosphate and potassium tripolyphosphate and sodium potassium tripolyphosphate can also be used according to the invention.

If phosphates are used as detergents or cleaning agents in the context of the present application, preferred agents comprise these phosphate (s), preferably alkali metal phosphate (s), more preferably pentasodium or pentapotassium triphosphate (sodium or pentasodium) Potassium tripolyphosphate), in amounts of from 5 to 80% by weight, preferably from 15 to 75% by weight, in particular from 20 to 70% by weight, based in each case on the weight of the washing or cleaning agent.

It is preferred in particular to use potassium tripolyphosphate and sodium tripolyphosphate in a weight ratio of more than 1: 1, preferably more than 2: 1, preferably more than 5: 1, more preferably more than 10: 1 and in particular more than 20: 1. It is particularly preferred to use exclusively potassium tripolyphosphate without admixtures of other phosphates.

Further builders are the alkali carriers. Suitable alkali carriers are, for example, alkali metal hydroxides, alkali metal carbonates, alkali metal hydrogencarbonates, alkali metal sesquicarbonates, the alkali metal silicates mentioned, alkali metal silicates and mixtures of the abovementioned substances, preference being given to using alkali metal carbonates, in particular sodium carbonate, sodium bicarbonate or sodium sesquicarbonate for the purposes of this invention. Particularly preferred is a builder system comprising a mixture of tripolyphosphate and sodium carbonate. Also particularly preferred is a builder system comprising a mixture of tripolyphosphate and sodium carbonate and sodium disilicate. Because of their compared with other builders low chemical compatibility with the other ingredients of detergents or cleaners, the alkali metal hydroxides are preferably only in small amounts, preferably in amounts below 10 wt .-%, preferably below 6 wt .-%, more preferably below 4 wt .-% and in particular below 2 wt .-%, each based on the total weight of the detergent or cleaning agent used. Particularly preferred are agents which, based on their total weight, contain less than 0.5% by weight and in particular no alkali metal hydroxides.

Particularly preferred is the use of carbonate (s) and / or bicarbonate (s), preferably alkali metal carbonate (s), more preferably sodium carbonate, in amounts of 2 to 50% by weight, preferably from 5 to 40 wt .-% and in particular from 7.5 to 30 wt .-%, each based on the weight of the washing or cleaning agent. Particular preference is given to compositions which, based on the weight of the washing or cleaning agent, contain less than 20% by weight, preferably less than 17% by weight, preferably less than 13% by weight and in particular less than 9% by weight of carbonate ( e) and / or bicarbonate (s), preferably alkali metal carbonate (s), particularly preferably sodium carbonate.

Particularly suitable organic co-builders are polycarboxylates / polycarboxylic acids, polymeric polycarboxylates, aspartic acid, polyacetals, dextrins, other organic cobuilders (see below) and phosphonates. These classes of substances are described below.

Useful organic builder substances are, for example, the polycarboxylic acids which can be used in the form of their sodium salts, polycarboxylic acids meaning those carboxylic acids which carry more than one acid function. These are, for example, citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), if such use is not objectionable for ecological reasons, and mixtures of these. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures thereof.

The acids themselves can also be used. In addition to their builder effect, the acids also typically have the property of an acidifying component and thus also serve to set a lower and milder pH of detergents or cleaners. In particular, citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any desired mixtures of these can be mentioned here. Further suitable builders are polymeric polycarboxylates, for example the alkali metal salts of polyacrylic acid or polymethacrylic acid, for example those having a relative molecular weight of from 500 to 70,000 g / mol.

For the purposes of this document, the molecular weights stated for polymeric polycarboxylates are weight-average molar masses M _{w of} the particular acid form, which were determined in principle by means of gel permeation chromatography (GPC), a UV detector being used. The measurement was carried out against an external polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship with the polymers investigated. These data differ significantly from the molecular weight data in which polystyrene sulfonic acids are used as standard. The molar masses measured against polystyrenesulfonic acids are generally significantly higher than the molecular weights specified in this document.

Suitable polymers are, in particular, polyacrylates which preferably have a molecular weight of 2,000 to 20,000 g / mol. Because of their superior solubility, the short-chain polyacrylates, which have molar masses of from 2000 to 10000 g / mol, and particularly preferably from 3000 to 5000 g / mol, may again be preferred from this group.

Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their relative molecular weight, based on free acids, is generally from 2000 to 70000 g / mol, preferably from 20,000 to 50,000 g / mol and in particular from 30,000 to 40,000 g / mol.

The (co) polymeric polycarboxylates can be used either as a powder or as an aqueous solution. The content of detergents or cleaning agents in (co) polymeric polycarboxylates is preferably from 0.5 to 20% by weight, in particular from 3 to 10% by weight.

To improve the water solubility, the polymers may also contain allylsulfonic acids such as allyloxybenzenesulfonic acid and methallylsulfonic acid as a monomer.

Also particularly preferred are biodegradable polymers of more than two different monomer units, for example those which contain as monomers salts of acrylic acid and maleic acid and vinyl alcohol or vinyl alcohol derivatives or as monomers salts of acrylic acid and 2-alkylallylsulfonic acid and sugar derivatives , Further preferred copolymers are those which have as monomers preferably acrolein and acrylic acid / acrylic acid salts or acrolein and vinyl acetate.

Also to be mentioned as further preferred builders polymeric aminodicarboxylic acids, their salts or their precursors. Particular preference is given to polyaspartic acids or their salts.

Further suitable builder substances are polyacetals which can be obtained by reacting dialdehydes with polyolcarboxylic acids which have 5 to 7 C atoms and at least 3 hydroxyl groups. Preferred polyacetals are obtained from dialdehydes such as glyoxal, glutaraldehyde, terephthalaldehyde and mixtures thereof and from polyol carboxylic acids such as gluconic acid and / or glucoheptonic acid.

Further suitable organic builder substances are dextrins, for example oligomers or polymers of carbohydrates, which can be obtained by partial hydrolysis of starches. The hydrolysis can be carried out by customary, for example acid or enzyme catalyzed processes. Preference is given to hydrolysis products having average molar masses in the range from 400 to 500 000 g / mol. In this case, a polysaccharide with a dextrose equivalent (DE) in the range from 0.5 to 40, in particular from 2 to 30 is preferred, DE being a common measure of the reducing action of a polysaccharide compared to dextrose, which has a DE of 100 , is. Usable are both maltodextrins with a DE between 3 and 20 and dry glucose syrups with a DE between 20 and 37 and so-called yellow dextrins and white dextrins with higher molecular weights in the range from 2000 to 30,000 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.

Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate, are further suitable co-builders. Ethylenediamine-N, ^{N'-disuccinate} (EDDS) is preferably in the form of its sodium or magnesium salts. Also preferred in this context are glycerol disuccinates and glycerol trisuccinates. Suitable amounts are in zeolithhaltigen and / or silicate-containing formulations at 3 to 15 wt .-%.

Other useful organic cobuilders are, for example, acetylated hydroxycarboxylic acids or their salts, which may optionally also be present in lactone form and which contain at least 4 carbon atoms and at least one hydroxyl group and a maximum of two acid groups. In addition, all compounds capable of forming complexes with alkaline earth ions can be used as builders.

The polyhydroxy fatty acid amides are known substances which can usually be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.

The group of polyhydroxy fatty acid amides also includes compounds of the formula

The zinc compounds mentioned are preferably used in amounts which have a content of the zinc ions of between 0.02 and 10% by weight, preferably between 0.1 and 5.0% by weight and in particular between 0.2 and 1.0 Wt .-%, each based on the total glass corrosion inhibitor-containing agent effect. The exact content of the agent on the zinc salt or zinc salts is naturally dependent on the type of zinc salts - the less soluble the zinc salt used, the higher its concentration should be in the funds.

Since the insoluble zinc salts remain largely unchanged during the Geschirreinigungsvorgangs, the particle size of the salts is a criterion to be observed, so that the salts do not adhere to glassware or machine parts. Here are preferred agents in which the insoluble zinc salts have a particle size below 1.7 millimeters.

If the maximum particle size of the insoluble zinc salts is below 1.7 mm, insoluble residues in the dishwasher are not to be feared. Preferably, the insoluble zinc salt has an average particle size that is well below this value by the hazard Insoluble residues to further minimize, for example, an average particle size less than 250 microns. Again, this is even more true the less the zinc salt is soluble. In addition, the glass corrosion inhibiting effectiveness increases with decreasing particle size. For very poorly soluble zinc salts, the average particle size is preferably below 100 microns. For still less soluble salts, it may be even lower; For example, average particle sizes below 60 μm are preferred for the very poorly soluble zinc oxide.

Another preferred class of compounds are magnesium and / or zinc salt (s) of at least one monomeric and / or polymeric organic acid. These have the effect that, even with repeated use, the surfaces of glassware do not undergo corrosive changes, in particular no clouding, streaks or scratches, but also no iridescence of the glass surfaces.

Although all magnesium and / or zinc salt (s) of monomeric and / or polymeric organic acids can be used, yet the magnesium and / or zinc salts of monomeric and / or polymeric organic acids from the groups of unbranched saturated or unsaturated monocarboxylic acids, the branched saturated or unsaturated monocarboxylic acids, the saturated and unsaturated dicarboxylic acids, the aromatic mono-, di- and tricarboxylic acids, the sugar acids, the hydroxy acids, the oxo acids, the amino acids and / or the polymeric carboxylic acids are preferred.

The spectrum of the inventively preferred zinc salts of organic acids, preferably organic carboxylic acids, ranges from salts which are difficult or insoluble in water, ie a solubility below 100 mg / l, preferably below 10 mg / l, in particular below 0.01 mg / l have, to those salts which have a solubility in water above 100 mg / l, preferably above 500 mg / l, more preferably above 1 g / l and in particular above 5 g / l (all solubilities at 2O ⁰ C water temperature). The first group of zinc salts includes, for example, the zinc nitrate, the zinc oleate and the zinc stearate, and the group of soluble zinc salts includes, for example, zinc formate, zinc acetate, zinc lactate and zinc gluconate.

With particular preference is used as a glass corrosion inhibitor at least one zinc salt of an organic carboxylic acid, more preferably a zinc salt from the group zinc stearate, zinc oleate, zinc gluconate, zinc acetate, zinc lactate and / or Zinkeitrat used. Zinc ricinoleate, zinc abietate and zinc oxalate are also preferred.

In the context of the present invention, the content of detergents on zinc salt is preferably between 0.1 and 5% by weight, preferably between 0.2 and 4% by weight, and in particular between 0.2 and 4% by weight. from 0.4 to 3 wt .-%, or the content of zinc in oxidized form (calculated as Zn ²⁺ ) between 0.01 to 1 wt .-%, preferably between 0.02 to 0.5 wt. -% and in particular between 0.04 to 0.2 wt .-%, each based on the total weight of the glass corrosion inhibitor-containing agent.

corrosion inhibitors

Corrosion inhibitors serve to protect the items to be washed or the machine, with particular silver protectants being of particular importance in the field of automatic dishwashing. It is possible to use the known substances of the prior art. In general, silver protectants selected from the group of the triazoles, the benzotriazoles, the bisbenzotriazoles, the aminotriazoles, the alkylaminotriazoles and the transition metal salts or complexes can be used in particular. Particularly preferred to use are benzotriazole and / or alkylaminotriazole. Examples of 3-amino-5-alkyl-1, 2,4-triazoles preferably used according to the invention which may be mentioned are: propyl, butyl, pentyl, heptyl, octyl, nonyl, decyl -, Undecyl-, -Dodecyl-, -Isononyl-, Versatic-10-Alkyl-, -Phenyl-, -p-Tolyl-, - (4-tert-butylphenyl) -, - (4-Methoxyphenyl) -, - (2-, 3-, 4-pyridyl) -, - (2-thienyl) -, - (5-methyl-2-furyl) -, - (5-oxo-2-pyrrolidinyl) -, 3-amino-1, 2,4-triazole.

In addition, cleaner formulations often contain active chlorine-containing agents which can markedly reduce the corrosion of the silver surface. In chlorine-free cleaners, especially oxygen- and nitrogen-containing organic redox-active compounds, such as di- and trihydric phenols, e.g. Hydroquinone, pyrocatechol, hydroxyhydroquinone, gallic acid, Pho- roglucin, pyrogallol or derivatives of these classes of compounds used. Also, salt and complex inorganic compounds, such as salts of the metals Mn, Ti, Zr, Hf, V, Co and Ce are often used. Preferred here are the transition metal salts which are selected from the group of the manganese and / or cobalt salts and / or complexes, particularly preferably the cobalt (ammin) complexes, the cobalt (acetate) complexes, the cobalt (carbonyl) - Complexes, the chlorides of cobalt or manganese and manganese sulfate. Also, zinc compounds can be used to prevent corrosion on the items to be washed.

Instead of or in addition to the silver protectants described above, for example the benzotriazoles, redox-active substances can be used. These substances are preferably inorganic redox-active substances from the group of manganese, titanium, zirconium, hafnium, vanadium, cobalt and cerium salts and / or complexes, wherein the metals preferably in one of the oxidation states II, III, IV, V or VI are present.

The metal salts or metal complexes used should be at least partially soluble in water. The counterions suitable for salt formation include all conventional mono-, di-, or tri-negatively charged inorganic anions, e.g. Oxide, sulfate, nitrate, fluoride, but also organic anions such as e.g. Stearate.

Metal complexes in the context of the invention are compounds which consist of a central atom and one or more ligands and optionally additionally one or more of the above-mentioned. Anions exist. The central atom is one of the o.g. Metals in one of the above Oxidation states. The ligands are neutral molecules or anions that are mono- or polydentate; The term "ligand" within the meaning of the invention is e.g. in "Römpp Chemie Lexikon, Georg Thieme Verlag Stuttgart / New York, 9th edition, 1990, page 2507" explained in more detail. If, in a metal complex, the charge of the central atom and the charge of the ligand (s) do not add up to zero, either one or more of the above may be provided, depending on whether there is cationic or anionic charge excess. Anions or one or more cations, e.g. Sodium, potassium, ammonium ions, for charge balance. Suitable complexing agents are e.g. Citrate, acetylacetonate or 1-hydroxyethane-1, 1-diphosphonate.

The definition of "oxidation state" common in chemistry is e.g. in "Römpp Chemie Lexikon, Georg Thieme Verlag Stuttgart / New York, 9th edition, 1991, page 3168" reproduced.

Particularly preferred metal salts and / or metal complexes are selected from the group MnSO ₄ , Mn (II) citrate, Mn (II) stearate, Mn (II) acetylacetonate, Mn (II) - [1-hydroxyethane-1, 1- diphosphonate], V ₂ O ₅ , V ₂ O ₄ , VO ₂ , TiOSO ₄ , K ₂ TiF ₆ , K ₂ ZrF ₆ , CoSO ₄ , Co (NO ₃ ) ₂ , Ce (NO ₃ ) ₃ , and mixtures thereof, such that the metal salts and / or metal complexes are selected from the group MnSO ₄ , Mn (II) citrate, Mn (II) stearate, Mn (II) acetylacetonate, Mn (II) - [I -hydroxyethane-1, 1 - diphosphonate], V ₂ O ₅ , V ₂ O ₄ , VO ₂ , TiOSO ₄ , K ₂ TiF ₆ , K ₂ ZrF ₆ , CoSO ₄ , Co (NO ₃ ) ₂ , Ce (NO ₃ ) _{3 are used} with particular preference ,

These metal salts or metal complexes are generally commercially available substances which can be used for the purpose of silver corrosion protection without prior purification in detergents or cleaners. Thus, for example, the mixture of pentavalent and tetravalent vanadium (V ₂ O ₅ , VO ₂ , V ₂ O ₄ ) known from the SO ₃ production (contact method) is suitable, as well as by diluting a Ti (SO ₄ ) ₂ -solution resulting titanyl sulfate, TiOSO ₄ . The inorganic redox-active substances, in particular metal salts or metal complexes are preferably coated, ie completely coated with a waterproof material which is readily soluble in the cleaning temperatures, in order to prevent their premature decomposition or oxidation during storage. Preferred coating materials, which are applied by known methods, such as Sandwik from the food industry, are paraffins, microwaxes, waxes of natural origin such as carnauba wax, candellila wax, beeswax, higher melting alcohols such as hexadecanol, soaps or fatty acids. The coating material which is solid at room temperature is applied in the molten state to the material to be coated, for example by spinning finely divided material to be coated in a continuous stream through a likewise continuously produced spray zone of the molten coating material. The melting point must be selected so that the coating material dissolves easily during the silver treatment or melts quickly. The melting point should ideally be in the range between 45 ⁰ C and 65 ° C and preferably in the range 50 ° C to 6O ⁰ C.

The metal salts and / or metal complexes mentioned are contained in cleaning agents, preferably in an amount of 0.05 to 6 wt .-%, preferably 0.2 to 2.5 wt .-%, each based on the total corrosion inhibitor-containing agent.

disintegration aid

In order to facilitate the disintegration of preformed moldings, it is possible to incorporate disintegration aids, so-called tablet disintegrants, into these compositions in order to shorten the disintegration times. According to Römpp (9th edition, Vol. 6, p. 4440) and Voigt "Textbook of Pharmaceutical Technology" (6th edition, 1987, pp. 182-184), excipients are understood to mean excipients which are suitable for rapid disintegration of tablets in water or gastric juice and for the release of the drugs in resorbable form.

These substances, which are also referred to as "explosives" due to their effect, increase their volume upon ingress of water, whereby on the one hand the intrinsic volume increases (swelling), on the other hand pressure can also be generated via the release of gases, which reduces the tablet into smaller volumes Particles decay. Known disintegration aids are, for example, carbonate / citric acid systems, although other organic acids can also be used. Swelling disintegration aids are, for example, synthetic polymers such as polyvinylpyrrolidone (PVP) or natural polymers or modified natural substances such as cellulose and starch and their derivatives, alginates or casein derivatives. Disintegration aids are preferably used in amounts of from 0.5 to 10% by weight, preferably from 3 to 7% by weight and in particular from 4 to 6% by weight, based in each case on the total weight of the disintegration assistant-containing agent.

Preferred disintegrating agents used are cellulose-based disintegrating agents, so that preferred washing and cleaning agents contain such cellulose-based disintegrants in amounts of from 0.5 to 10% by weight, preferably from 3 to 7% by weight and in particular from 4 to 6% by weight. % contain. Pure cellulose has the formal gross composition (C ₆ H ₁₀ O ₅ ) _n and is formally a β-1,4-polyacetal of cellobiose, which in turn is composed of two molecules of glucose. Suitable celluloses consist of about 500 to 5000 glucose units and therefore have average molecular weights of 50,000 to 500,000. Cellulose-based disintegrating agents which can be used in the context of the present invention are also cellulose derivatives obtainable by polymer-analogous reactions of cellulose. Such chemically modified celluloses include, for example, products of esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. Celluloses in which the hydroxy groups have been replaced by functional groups which are not bonded via an oxygen atom can also be used as cellulose derivatives. The group of cellulose derivatives includes, for example, alkali metal celluloses, carboxymethylcellulose (CMC), cellulose esters and ethers, and aminocelluloses. The cellulose derivatives mentioned are preferably not used alone as disintegrating agents based on cellulose, but used in admixture with cellulose. The content of these mixtures of cellulose derivatives is preferably below 50% by weight, particularly preferably below 20% by weight, based on the cellulose-based disintegrating agent. It is particularly preferred to use cellulose-based disintegrating agent which is free of cellulose derivatives.

The cellulose used as a disintegration aid is preferably not used in finely divided form, but converted into a coarser form, for example granulated or compacted, before it is added to the premixes to be tabletted. The particle sizes of such disintegrating agents are usually above 200 .mu.m, preferably at least 90 wt .-% between 300 and 1600 .mu.m and in particular at least 90 wt .-% between 400 and 1200 microns. The above and described in more detail in the documents cited coarser disintegration aids, are preferred as disintegration aids and are commercially available, for example under the name of Arbocel ^® TF-30-HG from Rettenmaier available in the present invention.

As a further disintegrating agent based on cellulose or as a component of this component microcrystalline cellulose can be used. This microcrystalline cellulose is obtained by partial hydrolysis of celluloses under conditions which are only amorphous Attack areas of the celluloses (about 30% of the total cellulose mass) and completely dissolve them, leaving the crystalline areas (about 70%) undamaged. A subsequent desaggregation of the microfine celluloses produced by the hydrolysis yields the microcrystalline celluloses which have primary particle sizes of about 5 μm and, for example, can be compacted into granules having an average particle size of 200 μm.

Preferred disintegration auxiliaries, preferably a cellulose-based disintegration assistant, preferably in granular, cogranulated or compacted form, are present in the disintegrants in amounts of from 0.5 to 10% by weight, preferably from 3 to 7% by weight in particular from 4 to 6% by weight, based in each case on the total weight of the disintegrating agent-containing agent.

Furthermore, according to the invention, gas-evolving effervescent systems can furthermore be used as tablet disintegration auxiliaries. The gas-evolving effervescent system may consist of a single substance that releases a gas upon contact with water. Among these compounds, mention should be made in particular of magnesium peroxide, which liberates oxygen on contact with water. Usually, however, the gas-releasing effervescent system in turn consists of at least two constituents which react with one another to form gas. While a variety of systems are conceivable and executable here, which release, for example, nitrogen, oxygen or hydrogen, the bubble system used in detergents and cleaners can be selected both on the basis of economic and environmental considerations. Preferred effervescent systems consist of alkali metal carbonate and / or bicarbonate and an acidifying agent which is suitable for liberating carbon dioxide from the alkali metal salts in aqueous solution.

In the case of the alkali metal carbonates or bicarbonates, the sodium and potassium salts are clearly preferred over the other salts for reasons of cost. Of course, the relevant pure alkali metal carbonates or bicarbonates do not have to be used; Rather, mixtures of different carbonates and bicarbonates may be preferred.

Preferred as effervescent system 2 to 20 wt .-%, preferably 3 to 15 wt .-% and in particular 5 to 10 wt .-% of an alkali metal carbonate or hydrogen carbonate and 1 to 15, preferably 2 to 12 wt .-% and in particular 3 to 10% by weight of an acidifying agent, in each case based on the total weight of the agent used.

Suitable acidifying agents which release carbon dioxide from the alkali metal salts in aqueous solution are, for example, boric acid and also alkali metal hydrogensulfates, alkali metal dihydrogenphosphates and other inorganic salts. However, preference is given to organic acidification. used, wherein the citric acid is a particularly preferred Acidifizierungsmittel. However, it is also possible in particular to use the other solid mono-, oligo- and polycarboxylic acids. Tartaric acid, succinic acid, malonic acid, adipic acid, maleic acid, fumaric acid, oxalic acid and polyacrylic acid are again preferred from this group. Organic sulfonic acids such as amidosulfonic acid are also usable. A commercially available as an acidifier in the context of the present invention also preferably be used is Sokalan ^® DCS (trademark of BASF), a mixture of succinic acid (max. 31 wt .-%), glutaric acid (max. 50 wt .-%) and adipic acid ( at most 33% by weight).

Acidifying agents in the effervescent system from the group of organic di-, tri- and oligocarboxylic acids or mixtures are preferred.

fragrances

As perfume oils or perfumes, within the scope of the present invention, individual fragrance compounds, e.g. the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type are used. Fragrance compounds of the ester type are known e.g. Benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate, phenylethyl acetate, linalylbenzoate, benzylformate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and benzylsalicylate. The ethers include, for example, benzyl ethyl ether, to the aldehydes e.g. the linear alkanals having 8-18 C atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, to the ketones e.g. the alcohols include anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol; the hydrocarbons mainly include the terpenes such as limonene and pinene. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance. Such perfume oils may also contain natural fragrance mixtures such as are available from vegetable sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil. Muskateller, sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, galena oil and labdanum oil as well as orange blossom oil, neroliol, orange peel oil and sandalwood oil are also suitable.

The general description of the perfumes that can be used (see above) generally represents the different substance classes of fragrances. To be perceptible, a fragrance must be volatile, whereby besides the nature of the functional groups and the structure of the chemical compound, the molecular weight also plays an important role plays. For example, most odorants have molecular weights up to about 200 daltons, while molecular weights of 300 daltons and above are more of an exception. Due to the different volatility of fragrances, the smell of a fragrance composed of several fragrances changes or Perfume during evaporation, wherein the odor impressions in top note, middle note or body and "base note" (end note or dry out) divided. Since odor perception is also largely based on the odor intensity, the top note of a perfume or fragrance does not consist solely of volatile compounds, while the base note consists for the most part of less volatile, ie adherent fragrances. For example, in the composition of perfumes, more volatile fragrances can be bound to certain fixatives, preventing them from evaporating too quickly. In the subsequent classification of the fragrances in "more volatile" or "adherent" fragrances so nothing about the olfactory impression and whether the corresponding fragrance is perceived as a head or middle note, nothing said.

Adhesion-resistant fragrances which can be used in the context of the present invention are, for example, the essential oils such as angelica root oil, aniseed oil, arnica blossom oil, basil oil, bay oil, bergamot oil, champacell blossom oil, fir pine oil, pinecone oil, elemi oil, eucalyptus oil, fennel oil, pine needle oil, galbanum oil, Geranium oil, ginger grass oil, guaiac wood oil, gurdy balm oil, helichrysum oil, ho oil, ginger oil, iris oil, cajeput oil, calamus oil, chamomile oil, camphor oil, kanga oil, cardamom oil, cassia oil, pine needle oil, copaϊva balsam oil, coriander oil, spearmint oil, caraway oil, cumin oil, lavender oil, Lemongrass oil, lime oil, mandarin oil, lemon balm oil, musk oil, myrrh oil, clove oil, neroli oil, niaouli oil, olibanum oil, orange oil, origanum oil, palmarosa oil, patchouli oil, pearl balsam oil, petitgrain oil, pepper oil, peppermint oil, pimento oil, pine oil, rose oil, rosemary oil, sandalwood oil, Celery oil, spiked oil, star aniseed oil, turpentine oil, thuja oil, thyme oil, verbena oil, vetiver oil, juniper berry oil, wormwood oil, wintergreen oil, ylang-ylang oil, hyssop oil, cinnamon oil, cinnamon oil, lemon oil, lemon oil and cypress oil. But also the higher-boiling or solid fragrances of natural or synthetic origin can be used in the context of the present invention as adherent fragrances or fragrance mixtures, ie fragrances. These compounds include the following compounds and mixtures thereof: ambrettolide, α-amylcinnamaldehyde, anethole, anisaldehyde, anisalcohol, anisole, methyl anthranilate, acetophenone, benzylacetone, benzaldehyde, ethyl benzoate, benzophenone, benzyl alcohol, benzyl acetate, benzyl benzoate, benzyl formate , Benzyl valerate, borneol, bornyl acetate, α-bromostyrene, n-decyl aldehyde, n-dodecyl aldehyde, eugenol, eugenol methyl ether, eucalyptol, fernsol, fenchone, fenchyl acetate, geranyl acetate, geranyl formate, heliotropin, heptincarboxylic acid methyl ester, heptaldehyde, hydroquinone dimethyl ether, hydroxycinnamaldehyde , Hydroxy cinnamyl alcohol, indole, iron, isoeugenol, isoeugenol methyl ether, isosafrole, jasmon, camphor, karvakrol, karvon, p-cresol methyl ether, coumarin, p-methoxyacetophenone, methyl n-amyl ketone, methyl anthranilic acid methyl ester, p-methylacetophenone, methylchavikol, p-methylquinoline , Methyl-ß-naphthyl ketone, methyl-n-nonylacetaldehyde, methyl n-nonyl ketone, Muscon, β-naphtholethyl ether, β-naphthol methyl ether, nerol, nitrobenzene, n-nonylaldehyde, nonyl alcohol, n-octylaldehyde, p-oxyacetophenone, pentadecanolide, β-phenylethyl alcohol, phenylacetaldehyde dimethyacetal, phenyl acetic acid, pulegone, safrol, salicylic acid isoamyl ester, salicylic acid methyl ester, salicylic acid xylester, cyclohexyl salicylate, santalol, skatole, terpineol, thymes, thymol, γ-undelactone, vaniline, veratrum aldehyde, cinnamaldehyde, cinnamyl alcohol, cinnamic acid, cinnamic acid ethyl ester, cinnamic acid benzyl ester. The more volatile fragrances include in particular the lower-boiling fragrances of natural or synthetic origin, which can be used alone or in mixtures. Examples of more volatile fragrances are alkyl isothiocyanates (alkyl mustard oils), butanedione, limonene, linalool, linayl acetate and propionate, menthol, menthone, methyl-n-heptenone, phellandrene, phenylacetaldehyde, terpinyl acetate, citral, citronellal.

The fragrances can be processed directly, but it can also be advantageous to apply the fragrances on carriers that provide a slower fragrance release for long-lasting fragrance. As such carrier materials, for example, cyclodextrins have been proven, the cyclodextrin-perfume complexes can be additionally coated with other excipients.

dyes

Preferred dyes, the selection of which presents no difficulty to the skilled person, have a high storage stability and insensitivity to the other ingredients of the agents and to light and no pronounced substantivity to the substrates to be treated with the dye-containing agents such as textiles, glass, ceramics or plastic dishes do not stain them.

When selecting the colorant, it must be taken into account that in the case of textile detergents, the colorants do not have too high an affinity for textile surfaces, and in particular for synthetic fibers, whereas in the case of detergents an excessively high affinity for glass, ceramic or plasticware must be avoided , At the same time, it should also be taken into account when choosing suitable colorants that colorants have different stabilities to the oxidation. In general, water-insoluble colorants are more stable to oxidation than water-soluble colorants. Depending on the solubility and thus also on the sensitivity to oxidation, the concentration of the colorant in the detergents or cleaners varies. For highly soluble dyes, for example, the above-mentioned Basacid ^® Green or the above-mentioned Sandolan Blue ^®, are typically selected dye concentrations in the range of some 10 ^"2 to ^{10" 3} wt .-%. In the due to their brilliance, particularly preferred, but are less readily water-soluble pigment dyes, for example the above-mentioned Pigmosol ^® ATTO-dyes, the appropriate concentration of the colorant is in washing or cleaning agents, however, typically a few 10 ^"3 to ^{10" 4} wt .-% , Dyeing agents which can be oxidatively destroyed in the washing process and mixtures thereof with suitable blue dyes, so-called blue toners, are preferred. It has proved to be advantageous to use colorants which are soluble in water or at room temperature in liquid organic substances. Suitable examples are anionic colorants, for example anionic nitrosofarbstoffe. One possible dye is, for example, naphthol green (Color Index (CI) Part 1: Acid Green 1; Part 2: 10020). Which as a commercial product, for example, as Basa- cid ^® Green 970 from BASF, Ludwigshafen, is obtainable, and mixtures of these with suitable blue dyes. Further suitable colorants Pigmosol come ^® Blue 6900 (CI 74160), Pigmosol ^® Green 8730 (CI 74260), Basonyl ^® Red 545 FL (CI 45170), Sandolan® ^® rhodamine EB400 (CI 45100), Basacid® ^® Yellow 094 (CI 47005) Sicovit ^® Patentblau 85 e 131 (CI 42051), Acid Blue 183 (CAS 12217-22-0, Cl Acidblue 183), pigment Blue 15 (Cl 74160), Supranol Blue ^® GLW (CAS 12219-32-8, Cl Acidblue 221 )), Nylosan Yellow ^® N-7GL SGR (CAS 61814-57-1, Cl Acidyellow 218) and / or Sandolan Blue ^® (Cl Acid Blue 182, CAS 12219-26-0) is used.

In addition to the components described in detail so far, the detergents and cleaners can contain further ingredients which further improve the performance and / or aesthetic properties of these compositions. Preferred agents contain one or more of the group of electrolytes, pH adjusters, fluorescers, hydrotopes, foam inhibitors, silicone oils, anti redeposition agents, optical brighteners, grayness inhibitors, anti-shrinkage agents, crease inhibitors, dye transfer inhibitors, antimicrobial agents, germicides, fungicides, antioxidants, antistatic agents, ironing aids , Phobic and impregnating agents, swelling and anti-slip agents and UV absorbers.

As electrolytes from the group of inorganic salts, a wide number of different salts can be used. Preferred cations are the alkali and alkaline earth metals, preferred anions are the halides and sulfates. From a manufacturing point of view, the use of NaCl or MgCl ₂ in the washing or cleaning agents is preferred.

In order to bring the pH of detergents or cleaners into the desired range, the use of pH adjusters may be indicated. Can be used here are all known acids or alkalis, unless their use is not for technical application or environmental reasons or for reasons of consumer protection prohibited. Usually, the amount of these adjusting agents does not exceed 1% by weight of the total formulation.

Suitable foam inhibitors are, inter alia, soaps, oils, fats, paraffins or silicone oils, which may optionally be applied to support materials. Suitable carrier materials are, for example, inorganic salts such as carbonates or sulfates, cellulose derivatives or silicates and mixtures of the abovementioned materials. In the context of the present application 08

72

Preferred agents include paraffins, preferably unbranched paraffins (n-paraffins) and / or silicones, preferably linear-polymeric silicones, which are constructed according to the scheme (R ₂ SiO) X and are also referred to as silicone oils. These silicone oils are usually clear, colorless, neutral, odorless, hydrophobic liquids having a molecular weight between 1,000 and 150,000, and viscosities between 10 and 1,000,000 mPa.s.

Suitable anti-redeposition agents, which are also referred to as soil repellents, are, for example, nonionic cellulose ethers such as methylcellulose and methylhydroxypropylcellulose with a proportion of methoxy groups of 15 to 30% by weight and of hydroxypropyl groups of 1 to 15% by weight, based in each case on the nonionic cellulose ether as well as the known from the prior art polymers of phthalic acid and / or terephthalic acid or derivatives thereof, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionic and / or nonionic modified derivatives thereof. Especially preferred of these are the sulfonated derivatives of the phthalic and terephthalic acid polymers.

Optical brighteners (so-called "whiteners") may be added to laundry detergents or cleaners to remove graying and yellowing of the treated fabrics which will attract the fiber and cause lightening and fake bleaching by exposing invisible ultraviolet radiation to visible, longer wavelength light . wherein the absorbed from sunlight ultraviolet light is radiated as pale bluish fluorescence and produces the yellow shade of the grayed or yellowed laundry pure white convert Suitable compounds originate for example from the substance classes of the 4,4 ^{'diamino-2,2'} - stilbenedisulfonic (flavonic), ^{4,4'-biphenylene} -Distyryl, Methylumbelliferone, coumarins, dihydroquinolinones, 1, 3-diaryl pyrazolines, naphthalimides, benzoxazole, benzisoxazole, and benzimidazole systems, and pyrene derivatives substituted by heterocycles.

Grayness inhibitors have the task of keeping the dirt detached from the fiber suspended in the liquor and thus preventing the dirt from being rebuilt. Water-soluble colloids of mostly organic nature are suitable for this purpose, for example the water-soluble salts of polymeric carboxylic acids, glue, gelatin, salts of ether sulfonic acids or cellulose or salts of acidic sulfuric acid esters of cellulose or starch. Also, water-soluble polyamides containing acidic groups are suitable for this purpose. It is also possible to use soluble starch preparations and starch products other than those mentioned above, for example degraded starch, aldehyde starches etc. Polyvinylpyrrolidone is also useful. Also usable as graying inhibitors are cellulose ethers such as carboxymethylcellulose (sodium salt), methylcellulose, hydroxyalkylcellulose and mixed ethers such as methylhydroxyethylcellulose, methylhydroxypropylcellulose, methylcarboxymethylcellulose and mixtures thereof. Since textile fabrics, in particular of rayon, rayon, cotton and their mixtures, can tend to wrinkle because the individual fibers are sensitive to bending, buckling, pressing and crushing transversely to the fiber direction, synthetic anti-crease agents can be used. These include, for example, synthetic products based on fatty acids, fatty acid esters, fatty acid amides, alkylol esters, -alkylolamides or fatty alcohols, which are usually reacted with ethylene oxide, or products based on lecithin or modified phosphoric acid ester.

Phobic and impregnation processes are used to furnish textiles with substances that prevent the deposition of dirt or facilitate its leaching ability. Preferred repellents and impregnating agents are perfluorinated fatty acids, also in the form of their aluminum and zirconium salts, organic silicates, silicones, polyacrylic acid esters with perfluorinated alcohol component or polymerizable compounds coupled with perfluorinated acyl or sulfonyl radical. Antistatic agents may also be included. The antisoiling equipment with repellents and impregnating agents is often classified as an easy-care finish. The penetration of the impregnating agent in the form of solutions or emulsions of the active substances in question can be facilitated by adding wetting agents which reduce the surface tension. A further field of application of repellents and impregnating agents is the water-repellent finish of textiles, tents, tarpaulins, leather, etc., in which, in contrast to waterproofing, the fabric pores are not closed, so the fabric remains breathable (hydrophobing). The water repellents used for hydrophobizing coat textiles, leather, paper, wood, etc. with a very thin layer of hydrophobic groups, such as longer alkyl chains or siloxane groups. Suitable hydrophobizing agents are e.g. Paraffins, waxes, metal soaps etc. with additions of aluminum or zirconium salts, quaternary ammonium compounds with long-chain alkyl radicals, urea derivatives, fatty acid-modified melamine resins, chromium complex salts, silicones, organotin compounds and glutaric dialdehyde as well as perfluorinated compounds. The hydrophobized materials do not feel greasy; nevertheless, similar to greasy substances, water droplets emit from them without moistening. Thus, e.g. Silicone-impregnated textiles have a soft feel and are water and dirt repellent; Stains from ink, wine, fruit juices and the like are easier to remove.

Antimicrobial agents can be used to combat microorganisms. Depending on the antimicrobial spectrum and mechanism of action, a distinction is made between bacteriostats and bactericides, fungistatics and fungicides, etc. Important substances from these groups are, for example, benzalkonium chlorides, alkylarylsulfonates, halophenols and phenolmercuric acetate, although it is entirely possible to do without these compounds. To prevent undesirable changes to the detergents and cleaners and / or the treated fabrics caused by exposure to oxygen and other oxidative processes, the compositions may contain anti-oxidants. This class of compounds includes, for example, substituted phenols, hydroquinones, catechols and aromatic amines, as well as organic sulfides, polysulfides, dithiocarbamates, phosphites and phosphonates.

Increased comfort may result from the additional use of antistatic agents. Antistatic agents increase the surface conductivity and thus allow an improved drainage of formed charges. External antistatic agents are generally substances with at least one hydrophilic molecule ligand and give a more or less hygroscopic film on the surfaces. These mostly surface-active antistatic agents can be subdivided into nitrogen-containing (amines, amides, quaternary ammonium compounds), phosphorus-containing (phosphoric acid esters) and sulfur-containing (alkyl sulfonates, alkyl sulfates) antistatic agents. Lauryl (or stearyl) di methylbenzyiammoniumchloride are also suitable as antistatic agents for textiles or as an additive to detergents, in addition, a softening effect is achieved.

Softeners can be used to care for the textiles and to improve the textile properties such as a softer "handle" (avivage) and reduced electrostatic charge (increased wearing comfort). The active substances in fabric softening formulations are "esterquats", quaternary ammonium compounds having two hydrophobic radicals, such as disteryldimethylammonium chloride, which, however, due to its insufficient biodegradability, is increasingly being replaced by quaternary ammonium compounds which in their hydrophobic radicals are ester groups as predetermined breaking points for the biological Contain degradation. Such "esterquats" with improved biodegradability are obtainable, for example, by esterifying mixtures of methyldiethanolamine and / or triethanolamine with fatty acids and then quaternizing the reaction products with alkylating agents in a manner known per se. Further suitable as a finish is dimethylolethyleneurea.

Silicone derivatives can be used to improve the water absorbency, rewettability of the treated fabrics, and ease of ironing the treated fabrics. These additionally improve the rinsing out of detergents or cleaning agents by their foam-inhibiting properties. Preferred silicone derivatives are, for example, polydialkyl or alkylaryl siloxanes in which the alkyl groups have one to five carbon atoms and are completely or partially fluorinated. Preferred silicones are polydimethylsiloxanes, which may optionally be derivatized and are then amino-functional or quaternized or have Si-OH, Si-H and / or Si-Cl bonds. Further preferred silicones are the polyalkylene oxide-modified polysiloxanes, ie polysiloxanes which comprise, for example, polyethylene glycols and the polyalkylene oxide-modified dimetylpolysiloxanes. Finally, according to the invention, it is also possible to use UV absorbers which are absorbed by the treated textiles and improve the light resistance of the fibers. Compounds which have these desired properties are, for example, the compounds which are active by radiationless deactivation and derivatives of benzophenone having substituents in the 2- and / or 4-position. Also suitable are substituted benzotriazoles, in the 3-position phenyl-substituted acrylates (cinnamic acid derivatives), optionally with cyano groups in the 2-position, salicylates, organic Ni complexes and natural substances such as umbelliferone and the endogenous urocanic acid.

Protein hydrolyzates are due to their fiber-care effect further in the context of the present invention preferred active substances from the field of detergents and cleaners. Protein hydrolysates are product mixtures obtained by acid, alkaline or enzymatically catalyzed degradation of proteins (proteins). According to the invention, protein hydrolysates of both vegetable and animal origin can be used. Animal protein hydrolysates are, for example, elastin, collagen, keratin, silk and milk protein protein hydrolysates, which may also be present in the form of salts. Preferred according to the invention is the use of protein hydrolysates of plant origin, e.g. Soy, almonds, rice, pea, potato and wheat protein hydrolysates. Although the use of the protein hydrolysates is preferred as such, amino acid mixtures or individual amino acids obtained otherwise, such as, for example, arginine, lysine, histidine or pyrroglutamic acid, may also be used in their place. Also possible is the use of derivatives of protein hydrolysates, for example in the form of their fatty acid condensation products.

The non-aqueous solvents which can be used according to the invention include, in particular, the organic solvents, of which only the most important can be listed here: alcohols (methanol, ethanol, propanols, butanols, octanols, cyclohexanol), glycols (ethylene glycol, diethylene glycol) , Ethers and glycol ethers (diethyl ether, dibutyl ether, anisole, dioxane, tetrahydrofuran, mono-, di-, tri-, polyethylene glycol ethers), ketones (acetone, butanone, cyclohexanone), esters (acetic acid esters, glycol esters), amides and others Nitrogen compounds (dimethylformamide, pyridine, N-methylpyrrolidone, acetonitrile), sulfur compounds (carbon disulfide, dimethyl sulfoxide, sulfolane), nitro compounds (nitrobenzene), halogenated hydrocarbons (dichloromethane, chloroform, tetrachloromethane, tri-, tetrachloroethene, 1, 2-dichloroethane, chlorofluorocarbons), hydrocarbons (benzene, petroleum ether, cyclohexane, methylcyclohexane, decalin, terpene solvent, benzene, toluene ol, XyIoIe). Alternatively, instead of the pure solvents, their mixtures, which advantageously combine, for example, the dissolution properties of various solvents, can also be used. Such a solvent mixture which is particularly preferred in the context of the present application is, for example Benzine, a mixture of various hydrocarbons suitable for dry cleaning, preferably containing C12 to C14 hydrocarbons above 60% by weight, more preferably above 80% by weight and in particular above 90% by weight, based in each case on the total weight of Mixture, preferably having a boiling range of 81 to 110 ⁰ C.
