Abstract
Description
Die vorliegende Erfindung betrifft eine tensidhaltige Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion und betrifft insbesondere eine tensidhaltige Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion, die von einer Umhüllung umgeben ist und in ihrem Innern ein feinverteiltes Gas enthält.The present invention relates to a surfactant-containing detergent, detergent or detergent portion and, in particular, relates to a surfactant-containing detergent, detergent or cleaning agent portion, which is surrounded by a casing and contains a finely divided gas in its interior.
Tensidhaltige Zubereitungen mit darin enthaltenen feinverteilten Gasen sind bekannt und können beispielsweise als tensidhaltige Schäume vorliegen, wie sie für viele Anwendungen erhältlich sind. So können Rasiercremes als Schäume bereitgestellt werden, können das Haar festigende oder anderweitig konditionierende Mittel aufgeschäumt werden, können Reiniger für Glasflächen und andere harte Oberflächen, beispielsweise im Bereich Bad und/oder Küche, in Schaum-Form aufgetragen werden und können Reiniger für Teppiche und Polster vorteilhafterweise als Schäume aufgetragen bzw. appliziert werden. In jüngerer Zeit wurde auch von reinigenden bzw. Flecken beseitigenden Mitteln für Textilien berichtet, die in Form eines Schaums auf zu reinigende Stellen bzw. Flecken aufgetragen werden. Der Schaum ermöglicht eine gewisse "Standzeit" des reinigenden Mittels auf der zu reinigenden Stelle bzw. auf dem Flecken, ohne die Zusammensetzung des reinigenden Mittels stark in Richtung auf eine hohe Viskosität verändern zu müssen, die früher ein Mittel dazu war, den Reiniger an der Stelle zu halten, an der seine Einwirkung erwünscht war.Surfactant-containing preparations containing finely divided gases are known and can be present, for example, as surfactant-containing foams, as are available for many applications. Thus, shaving creams can be provided as foams, the hair-setting or otherwise conditioning agents can be foamed, glass surface cleaners and other hard surfaces, for example in the bathroom and / or kitchen area, can be applied in foam form and can clean carpets and upholstery be advantageously applied or applied as foams. More recently, cleansing agents have also been reported for textiles which are applied in the form of a foam to spots or spots to be cleaned. The foam allows a certain "life" of the cleaning agent on the spot to be cleaned or on the spot, without having to change the composition of the cleaning agent strongly towards a high viscosity, which was previously a means to clean the cleaner at the To hold place where his action was desired.

Suitable surfactants of the sulfonate type are preferably C 9-13- alkylbenzenesulfonates, olefinsulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates, such as those obtained, for example, from C 12-18 monoolefins having terminal or internal double bonds by sulfonating with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation obtained. Also suitable are alkanesulfonates which are obtained from C 12-18 alkanes, for example by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization.

Weiterhin kann es bevorzugt sein, neben anionischen und nichtionischen Tensiden auch kationische Tenside einzusetzen. Ihr Einsatz erfolgt dabei bevorzugt als Waschleistungsbooster, wobei nur kleine Mengen an kationischen Tensiden erforderlich sind. Werden kationische Tenside eingesetzt, so sind sie in den Schaum-Formkörpern bevorzugt in Mengen von 0,01 bis 10 Gew.-%, insbesondere von 0,1 bis 3,0 Gew.-% enthalten.Furthermore, it may be preferable to use not only anionic and nonionic surfactants but also cationic surfactants.

Für den Inhalt der erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen geeignete Gase können grundsätzlich alle denkbaren Gase sein, deren Verwendung ökonomisch vertretbar ist, die nicht mit einer oder mehreren anderen Komponenten der erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen in nachteiliger Weise in Wechselwirkung treten, die für den Verbraucher bei Lagerung und Gebrauch der Portionen nicht schädlich sind und die keine nachteilige Wirkung auf das Waschgut, Spülgut oder zu reinigende Gut haben. Als Gase kommen beispielsweise Einzelstoffe aus der Gruppe Luft, Stickstoff, Sauerstoff, Kohlendioxid, Helium, Argon, Distickstoffoxid, Stickstoffmonoxid, Fluorkohlenstoff(e) wie beispielsweise CFC, HCFC und HFC und Alkan(e) wie beispielsweise Methan, Ethan, Propan, Butan, Pentan oder Hexan infrage. Die genannten Gase können einzeln oder in beliebigen Mischungen (auch Mischungen in beliebigen Mengenverhältnissen der beteiligten Gase untereinander) von zwei oder mehr von Ihnen Verwendung finden.Suitable gases for the content of the detergent, detergent or cleaner portions according to the invention may in principle be any conceivable gas whose use is economically justifiable, which is not disadvantageous with one or more other components of the inventive detergent, detergent or cleaner portions Interacting manner that are not harmful to the consumer during storage and use of the portions and that have no adverse effect on the laundry, items to be washed or to be cleaned. Examples of gases are individual substances from the group air, nitrogen, oxygen, carbon dioxide, helium, argon, nitrous oxide, nitrogen monoxide, fluorocarbon (s) such as CFC, HCFC and HFC and alkane (s) such as methane, ethane, propane, butane, Pentane or hexane in question. The gases mentioned can be used individually or in any mixtures (including mixtures in any proportions of the gases involved) among two or more of them.
Unter bestimmten Bedingungen bildet das Gas/bilden die Gase zusammen mit anderen waschaktiven, spülaktiven oder reinigungsaktiven Komponenten der erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen einen Schaum. Der aus dem/den Tensid(en) bzw. ihren Lösungen in Wasser und dem/den Gas(en) gebildete Schaum ist eine Dispersion von Gas(en) in einer relativ kleinen flüssigen Phase, wobei die die Tensid(e) umfassende Phase die kontinuierliche flüssige Phase ist und die Gasphase hierin dispergiert ist. Typischerweise haben die Gasblasen der dispergierten Phase eine mehr oder weniger breite Verteilung der Größe; die Werte der Blasengröße können herstellungsbedingt im Bereich von 1 nm bis 10 mm schwanken. Die mittlere Blasendurchmesser liegt bevorzugt im Bereich von 2 nm bis 1 mm. Natürlich können auch kleinere oder größere Gasblasen realisiert werden.Under certain conditions, the gas forms a foam together with other detergent-active, rinse-active or detergent-active components of the detergent, detergent or cleaner portions according to the invention. The foam formed from the surfactant (s) or their solutions in water and the gas (s) is a dispersion of gas (s) in a relatively small liquid phase, the phase comprising the surfactant (s) comprising the continuous liquid phase and the gas phase is dispersed therein. Typically, the dispersed phase gas bubbles have a more or less wide distribution of size; The values of the bubble size can fluctuate in the range of 1 nm to 10 mm due to the production. The mean bubble diameter is preferably in the range of 2 nm to 1 mm. Of course, smaller or larger gas bubbles can be realized.
Als weitere Komponente umfassen die Schaum-Formkörper gemäß der vorliegenden Erfindung eine in Wasser desintegrierbare Umhüllung. Darunter wird eine vollständig die anderen Komponenten der Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion umgebende und diese zumindest mechanisch, weiter bevorzugt auch weitgehend gas- und feuchtigkeitsdicht von der Außenumgebung abschirmende Umhüllung verstanden. Diese muß in Wasser desintegrierbar sein, also sich entweder ganz auflösen, was erfindungsgemäß bevorzugt ist, oder sich in Abhängigkeit von bestimmten Parametern wie Temperatur, Elektrolytkonzentration, pH-Wert, Enzymkonzentration oder anderer Parameter in der Wasch-, Spül- oder Reinigungsflotte sukzessive vollständig oder partiell lösen.As a further component, the foam moldings according to the present invention comprise a water-disintegratable coating. This is understood to mean a sheath which completely surrounds the other components of the detergent, detergent or cleaning agent portion and at least mechanically, more preferably also largely gas and moisture-tight, shielding it from the outside environment. This must be disintegratable in water, so either dissolve completely, which is preferred according to the invention, or depending on certain parameters such as temperature, electrolyte concentration, pH, enzyme concentration or other parameters in the washing, rinsing or cleaning liquor successively complete or partially solve.
In einer bevorzugten Ausführungsform der Erfindung umfassen die Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen als in Wasser desintegrierbare Umhüllung ein wasserlösliches Polymer-Material. Dabei besteht die Möglichkeit, daß die Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion eine Umhüllung aus einem oder mehreren wasserlöslichen Polymer-Material(ien) umgibt oder daß mehrere Umfassungen aus gleichen oder unterschiedlichen Materialien enthalten sind. Im Rahmen der vorliegenden Erfindung ist das Vorhandensein einer Umhüllung bevorzugt, was Vorteile bei der Materialwahl und auch im Hinblick auf das Erfordernis bringt, daß sich das wasserlösliche Polymer-Material letzten Endes rückstandsfrei in der Wasch-, Spül- oder Reinigungsflotte lösen muß. Die Umhüllung(en) kann/können aus einem einzigen wasserlöslichen Polymer-Material oder kann/können aus mehreren verschiedenen Polymer-Materialien gebildet sein, die gegebenenfalls unterschiedliche Löslichkeit in Wasser aufweisen können. Im Hinblick auf die vorliegende Aufgabenstellung kann erfindungsgemäß die Verwendung mehrerer verschiedenen Polymer-Materialien besonders bevorzugt sein, worauf nachfolgend gesondert eingegangen wird.In a preferred embodiment of the invention, the detergent, rinse or detergent portions comprise a water-soluble polymer material as the water-disintegratable wrapper. There is the possibility that the detergent, detergent or cleaning agent portion encloses an envelope of one or more water-soluble polymer material (s) or that more enclosures of the same or different materials are included. In the context of the present invention, the presence of an envelope is preferred, which brings advantages in the choice of materials and also with regard to the requirement that the water-soluble polymer material must ultimately dissolve residue-free in the washing, rinsing or cleaning fleet. The wrapper (s) may be formed from a single water-soluble polymer material or may be formed from a plurality of different polymeric materials which may optionally have different solubility in water. In view of the present task, according to the invention, the use of several different polymer materials may be particularly preferred, which will be discussed separately below.
Die spezielle Form der in Wasser desinterierbaren Umhüllung der Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion der vorliegenden Erfindung ist nicht kritisch. So können die Umhüllungen flächig ausgebildet sein oder auch in Form von Kapseln oder ähnlichen Formkörpern vorliegen. Bevorzugt sind natürlich Formkörper, die eine maximale Kontaktfläche zwischen der Flotte und der zu desintegrierenden Umhüllung sicherstellen.The particular form of the water-deintermissable envelope of the detergent, rinse or detergent portion of the present invention is not critical. Thus, the sheaths may be formed flat or in the form of capsules or similar shaped bodies. Of course, moldings which ensure a maximum contact surface between the liquor and the casing to be disintegrated are preferred.
Es entspricht einer weiteren bevorzugten Ausführungsform der Erfindung, daß die Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion als in Wasser desintegrierbare Umhüllung ein wasserlösliches Polymer unterschiedlicher Schichtdicke umfaßt. Bei gleichbleibendem Material lösen sich die Bereiche der Umhüllung mit geringerer Schichtdicke schneller als diejenigen mit größerer Schichtdicke, so daß sich mit fortschreitendem Lösungsprozeß der Umhüllung in Wasser eine mit Poren oder Löchern versehene Umhüllung ausbildet. Durch die Poren oder Löcher kann Wasser in das Innere der Umhüllung eintreten, den von der Umhüllung umgebenen Inhalt der Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion sukzessive lösen und durch die Poren oder Löcher nach außen, d. h. in die Waschflotte, Spülflotte oder Reinigungsflotte, transportieren.It is another preferred embodiment of the invention that the detergent, rinse or detergent portion comprises a water-soluble polymer of different layer thickness as the water-disintegratable wrapper. If the material remains the same, the regions of the coating with a smaller layer thickness dissolve faster than those with a greater layer thickness, so that a coating provided with pores or holes is formed in water as the dissolution process of the coating progresses. Through the pores or holes, water may enter the interior of the enclosure, gradually dissolve the contents of the detergent, detergent or detergent portion surrounded by the enclosure, and through the pores or holes to the outside, i. H. into the wash liquor, rinse liquor or cleaning liquor transport.
Ein ähnlicher Effekt kann sich bei einer weiteren, ebenfalls bevorzugten Ausführungsform der Erfindung einstellen, gemäß der die Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion als in Wasser desintegrierbare Umhüllung ein Polymer-Material mit Bereichen guter Wasserlöslichkeit und mit Bereichen weniger guter Wasserlöslichkeit umfaßt. Dies kann Resultat einer unterschiedlichen Wasserlöslichkeit des Polymers selbst sein, beispielsweise durch seine unterschiedliche chemische Natur (Beispiel: Polyvinylalkohole mit unterschiedlichem Acetalisierungsgrad), oder kann Resultat der Tatsache sein, daß Polymere mit unterschiedlicher Wasserlöslichkeit gezielt gemischt werden oder daß in Polymer-Materialien mit beispielsweise weniger guter Wasserlöslichkeit andere Materialien (beispielsweise gut wasserlösliche anorganische oder organische Salze) eingelagert sind, die bei Kontakt mit Wasser schnell in der Waschflotte, Spülflotte oder Reinigungsflotte in Lösung gehen und so ebenfalls eine mit Poren oder Löchern versehene Struktur schaffen.A similar effect may be obtained in a further, likewise preferred embodiment of the invention, according to which the detergent, rinse or detergent portion comprises as the water-disintegratable wrapper a polymer material having areas of good water solubility and areas of less good water solubility. This may be the result of a different water solubility of the polymer itself, for example due to its different chemical nature (for example: polyvinyl alcohols with different degrees of acetalization), or may be the result of the fact that polymers with different water solubility are deliberately mixed or in polymer materials with, for example, less good water solubility other materials (for example, readily water-soluble inorganic or organic salts) are incorporated, which quickly go into contact with water in the wash liquor, wash liquor or cleaning liquor and thus also create a structure provided with pores or holes.
Als wasserlösliche Polymer-Materialien kommen grundsätzlich alle Polymer-Materialien infrage, die sich unter den gegebenen Bedingungen (Temperatur, pH-Wert, Konzentration an waschaktiven Komponenten) in wäßriger Phase mehr oder weniger vollständig lösen können. Die Polymer-Materialien können besonders bevorzugt den Gruppen (acetalisierter) Polyvinylalkohol, Polyvinylpyrrolidon, Polyethylenoxid, Gelatine, Cellulose und deren Derivate und Mischungen der genannten Materialien zugehören.As water-soluble polymer materials are basically all polymer materials in question, which under the given conditions (temperature, pH, concentration of detergent components) in aqueous phase can more or less completely solve. The polymer materials may particularly preferably belong to the groups (acetalised) polyvinyl alcohol, polyvinylpyrrolidone, polyethylene oxide, gelatin, cellulose and derivatives thereof and mixtures of said materials.

[-CH2-CH(OH)-CH(OH)-CH2-]
enthalten. Da das entsprechend Monomer (Vinylalkohol) in freier Form nicht beständig ist, werden Polyvinylalkohole über polymeranaloge Reaktionen durch Hydrolyse, technisch insbesondere durch alkalisch katalysierte Umesterung von Polyvinylacetaten mit Alkoholen, vorzugsweise mit Methanol, erhalten. Durch diese technischen Verfahren sind auch PVAL zugänglich, die einen vorbestimmten Restanteil an Acetat-Gruppen enthalten.Polyvinyl alcohols (abbreviated PVAL) are polymers of the general structure
[-CH 2 -CH (OH) -] n
in small quantities also structural units of the type
[-CH 2 -CH (OH) -CH (OH) -CH 2 -]
contain. Since the corresponding monomer (vinyl alcohol) is not stable in free form, polyvinyl alcohols are obtained via polymer-analogous reactions by hydrolysis, in particular by alkali-catalyzed transesterification of polyvinyl acetates with alcohols, preferably with methanol. By these technical methods, PVAL are also available which contain a predetermined residual amount of acetate groups.
Handelsübliche PVAL (z.B. Mowiol®-Typen der Firma Hoechst) kommen als weißgelbliche Pulver oder Granulate mit Polymerisationsgraden im Bereich von ca. 500 bis 2.500 (entsprechend Molmassen von ca. 20.000 bis 100.000 g/mol) in den Handel und haben unterschiedliche Hydrolysegrade von beispielsweise 98 bis 99 bzw. 87 bis 89 Mol-%. Sie sind also teilverseifte Polyvinylacetate mit einem Restgehalt an Acetyl-Gruppen von beispielsweise etwa 1 bis 2 bzw. 11 bis 13 Mol-%.Commercially available PVAL (eg Mowiol® grades from Hoechst) are commercially available as white-yellowish powders or granules with degrees of polymerization in the range of about 500 to 2,500 (corresponding to molar masses of about 20,000 to 100,000 g / mol) and have different degrees of hydrolysis, for example 98 to 99 or 87 to 89 mol%. So they are partially hydrolyzed polyvinyl acetates having a residual content of acetyl groups, for example, about 1 to 2 or 11 to 13 mol%.
Die Wasserlöslichkeit von PVAL kann man durch Nachbehandlung mit Aldehyden (Acetalisierung), durch Komplexierung mit Ni- oder Cu-Salzen oder durch Behandlung mit Dichromaten, Borsäure, Borax verringern und so gezielt auf gewünschte Werte einstellen. Folien aus PVAL sind weitgehend undurchdringlich für Gase wie Sauerstoff, Stickstoff, Helium, Wasserstoff, Kohlendioxid, lassen jedoch Wasserdampf hindurchtreten.The water solubility of PVAL can be reduced by aftertreatment with aldehydes (acetalization), 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.
Beispiele geeigneter wasserlöslicher PVAL-Folien sind die unter Bezeichnung "SOLUBLON®" von der Firma Syntana Handelsgesellschaft E. Harke GmbH & Co. erhältlichen PVAL-Folien. Deren Löslichkeit in Wasser läßt sich Grad-genau einstellen, und es sind Folien dieser Produktreihe erhältlich, die in allen für die Anwendung relevanten Temperaturbereichen in wäßriger Phase löslich sind.Examples of suitable water-soluble PVAL films are the PVAL films available under the name "SOLUBLON®" from Syntana Handelsgesellschaft E. Harke GmbH & Co. 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.
Polyvinylpyrrolidone, kurz als PVP bezeichnet, lassen sich durch die folgende allgemeine Formel beschreiben:
Polyethylenoxide, kurz PEOX, sind Polyalkylenglykole der allgemeinen Formel
H-[O-CH2-CH2]n-OH
die technisch durch basisch katalysierte Polyaddition von Ethylenoxid (Oxiran) in meist geringe Mengen Wasser enthaltenden Systemen mit Ethylenglykol als Startmolekül hergestellt werden. Sie haben Molmassen im Bereich von ca. 200 bis 5.000.000 g/mol, entsprechend Polymerisationsgraden n von ca. 5 bis >100.000. Polyethylenoxide besitzen eine äußerst niedrige Konzentration an reaktiven Hydroxy-Endgruppen und zeigen nur noch schwache Glykol-Eigenschaften.Polyethylene oxides, PEOX for short, are polyalkylene glycols of the general formula
H- [O-CH 2 -CH 2 ] n -OH
the technically by alkaline-catalyzed polyaddition of ethylene oxide (oxirane) in mostly small amounts of water-containing systems are prepared with ethylene glycol as the starting molecule. 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.
Gelatine ist ein Polypeptid (Molmasse: ca. 15.000 bis >250.000 g/mol), das vornehmlich durch Hydrolyse des in Haut und Knochen von Tieren enthaltenen Kollagens unter sauren oder alkalischen Bedingungen gewonnen wird. Die Aminosäuren-Zusammensetzung der Gelatine entspricht weitgehend der des Kollagens, aus dem sie gewonnen wurde, und variiert in Abhängigkeit von dessen Provenienz. Die Verwendung von Gelatine als wasserlösliches Hüllmaterial ist insbesondere in der Pharmazie in Form von Hart- oder Weichgelatinekapseln äußerst weit verbreitet. In Form von Folien findet Gelatine wegen ihres im Vergleich zu den vorstehend genannten Polymeren hohen Preises nur geringe Verwendung.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. The use of gelatin as water-soluble coating material is extremely widespread, especially in pharmacy in the form of hard or soft gelatin capsules. In the form of films, gelatin has little use because of its high price compared to the polymers mentioned above.
Bevorzugt sind im Rahmen der vorliegenden Erfindung auch Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen, deren Umhüllung aus wasserlöslicher Folie aus mindestens einem Polymer aus der Gruppe Stärke und Stärkederivate, Cellulose und Cellulosederivate, insbesondere Methylcellulose und Mischungen hieraus besteht.Also preferred within the scope of the present invention are detergent, dishwashing or cleaning agent portions whose coating consists of water-soluble film of at least one polymer from the group starch and starch derivatives, cellulose and cellulose derivatives, in particular methyl cellulose and mixtures thereof.
Stärke ist ein Homoglykan, wobei die Glucose-Einheiten α-glykosidisch verknüpft sind. Stärke ist aus zwei Komponenten unterschiedlichen Molekulargewichts aufgebaut: aus ca. 20 bis 30% geradkettiger Amylose (MG. ca. 50.000 bis 150.000) und 70 bis 80% verzweigtkettigem Amylopektin (MG. ca. 300.000 bis 2.000.000). Daneben sind noch geringe Mengen Lipide, Phosphorsäure und Kationen enthalten. Während die Amylose infolge der Bindung in 1,4-Stellung lange, schraubenförmige, verschlungene Ketten mit etwa 300 bis 1200 Glucose-Molekülen bildet, verzweigt sich die Kette beim Amylopektin nach durchschnittlich 25 Glucose-Bausteinen durch 1,6-Bindung zu einem astähnlichen Gebilde mit etwa 1.500 bis 12.000 Molekülen Glucose. Neben reiner Stärke sind zur Herstellung wasserlöslicher Umhüllungen der Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen im Rahmen der vorliegenden Erfindung auch Stärke-Derivate, die durch polymeranaloge Reaktionen aus Stärke erhältlich sind. Solche chemisch modifizierten Stärken umfassen dabei beispielsweise Produkte aus Veresterungen bzw. Veretherungen, in denen Hydroxy-Wasserstoffatome substituiert wurden. Aber auch Stärken, in denen die Hydroxy-Gruppen gegen funktionelle Gruppen, die nicht über ein Sauerstoffatom gebunden sind, ersetzt wurden, lassen sich als Stärke-Derivate einsetzen. In die Gruppe der Stärke-Derivate fallen beispielsweise Alkalistärken, Carboxymethylstärke (CMS), Stärkeester und -ether sowie Aminostärken.Starch is a homoglycan, wherein the glucose units are linked α-glycosidically. Starch is composed of two components of different molecular weight: from 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. While the amylose forms long, helical, entangled chains with about 300 to 1200 glucose molecules as a result of the binding in the 1,4-position, the chain branches in amylopectin after an average of 25 glucose building blocks by 1,6-bonding to a branch-like structure with about 1,500 to 12,000 molecules of glucose. In addition to pure starch, for the production of water-soluble coatings of detergent, detergent or detergent portions in the context of the present invention are also starch derivatives which are obtainable by polymer-analogous reactions of starch. Such chemically modified starches include, for example, products of esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. But even starches in which the hydroxy groups have been replaced by functional groups that are not bound by an oxygen atom, can 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.
Reine Cellulose weist die formale Bruttozusammensetzung (C6H10O5)n auf und stellt formal betrachtet ein β-1,4-Polyacetal von Cellobiose dar, die ihrerseits aus zwei Molekülen Glucose aufgebaut ist. Geeignete Cellulosen bestehen dabei aus ca. 500 bis 5000 Glucose-Einheiten und haben demzufolge durchschnittliche Molmassen von 50.000 bis 500.000. Als Desintegrationsmittel auf Cellulosebasis verwendbar sind im Rahmen der vorliegenden Erfindung auch Cellulose-Derivate, die durch polymeranaloge Reaktionen aus Cellulose erhältlich sind. Solche chemisch modifizierten Cellulosen umfassen dabei beispielsweise Produkte aus Veresterungen bzw. Veretherungen, in denen Hydroxy-Wasserstoffatome substituiert wurden. Aber auch Cellulosen, in denen die Hydroxy-Gruppen gegen funktionelle Gruppen, die nicht über ein Sauerstoffatom gebunden sind, ersetzt wurden, lassen sich als Cellulose-Derivate einsetzen. In die Gruppe der Cellulose-Derivate fallen beispielsweise Alkalicellulosen, Carboxymethylcellulose (CMC), Celluloseester und -ether sowie Aminocellulosen.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.
Bevorzugte Umhüllungen aus wasserlöslichem Polymer-Material bestehen aus einem Polymer mit einer Molmasse zwischen 5.000 und 500.000 Dalton, vorzugsweise zwischen 7.500 und 250.000 Dalton und insbesondere zwischen 10.000 und 100.000 Dalton. Das wasserlösliche Polymer-Material, das die Umhüllung bildet, weist vorzugsweise eine Dicke von 1 bis 150 µm, vorzugsweise von 2 bis 100 µm, besonders bevorzugt von 5 bis 75 µm und insbesondere von 10 bis 50 µm, auf.Preferred casings of water-soluble polymer material consist of a polymer with one molecular weight between 5,000 and 500,000 daltons, preferably between 7,500 and 250,000 daltons and in particular between 10,000 and 100,000 daltons. The water-soluble polymer material forming the cladding preferably has a thickness of from 1 to 150 μm, preferably from 2 to 100 μm, more preferably from 5 to 75 μm and in particular from 10 to 50 μm.
Diese wasserlöslichen Folien aus Polymer-Material können nach verschiedenen Herstellverfahren hergestellt werden. Hier sind prinzipiell Blas-, Kalandrier- und Gießverfahren zu nennen. Bei einem bevorzugten Verfahren werden die Folien dabei ausgehend von einer Schmelze mit Luft über einen Blasdorn zu einem Schlauch geblasen. Bei dem Kalandrierverfahren, das ebenfalls zu den bevorzugt eingesetzten Herstellverfahren gehört, werden die durch geeignete Zusätze plastifizierten Rohstoffe zur Ausformung der Folien verdüst. Hier kann es insbesondere erforderlich sein, an die Verdüsungen eine Trocknung anzuschließen. Bei dem Gießverfahren, das ebenfalls zu den bevorzugten Herstellverfahren gehört, wird eine wäßrige Polymerzubereitung auf eine beheizbare Trockenwalze gegeben, nach dem Verdampfen des Wassers wird optional gekühlt und die Folie als Film abgezogen. Gegebenenfalls wird dieser Film vor oder während des Abziehens zusätzlich abgepudert.These water-soluble films of polymer material can be produced by various manufacturing methods. Blow molding, calendering and casting processes should be mentioned here in principle. In a preferred method, the films are blown starting from a melt with air through a mandrel to a hose. In the case of the calendering process, which is likewise one of the preferred production processes, the raw materials plasticized by suitable additives are atomized to form the films. In particular, it may be necessary to attach drying to the atomizations. In the casting process, which is also one of the preferred production methods, an aqueous polymer preparation is placed on a heatable drying roller, after the evaporation of the water is optionally cooled and the film is peeled off as a film. Optionally, this film is additionally powdered before or during the removal.
Es entspricht einer weiteren, ebenfalls bevorzugten Ausführungsform der Erfindung, Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen bereitzustellen, die als in Wasser desintegrierbare Umhüllung eine Umhüllung aus einem kristallinen Material umfassen, wobei das kristalline Material organischer oder anorganischer Natur sein kann. Typische Beispiele organischer kristalliner Materialien sind alle wasserlöslichen kristallinen Materialien, insbesondere Zucker, während typische Beispiele anorganischer kristalliner Materialien wasserlösliche Salze, insbesondere Schwermetall-freie Salze sind. Besonders bevorzugt können dabei Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen sein, deren Umhüllungen aus einem kristallinen Material bestehen, das im Wasch-, Spül- oder Reinigungsprozeß eine spezielle Funktion übernehmen kann, wenn es durch den Lösevorgang in Wasser in die Waschflotte, Spülflotte oder Reinigungsflotte gelangt ist. Ein Beispiel hierfür sind Polyphosphate. Diese können im Wasser enthaltene Calcium- und Magnesium-Ionen komplexieren und dadurch dazu beitragen, daß eine Enthärtung des Wassers nicht separat (beispielsweise durch Salz-Zusatz in der Geschirrspülmaschine) durchgeführt werden muß.It is another, yet preferred embodiment of the invention to provide detergent, rinse or detergent portions which comprise a water-disintegratable wrapper as a crystalline material wrapper wherein the crystalline material may be organic or inorganic in nature. Typical examples of organic crystalline materials are all water-soluble crystalline materials, especially sugars, while typical examples of inorganic crystalline materials are water-soluble salts, especially heavy metal-free salts. Detergent, detergent or detergent portions may be particularly preferred, the sheaths of which consist of a crystalline material which can assume a special function in the washing, rinsing or cleaning process when it is in the wash liquor, rinsing liquor by the dissolution process or cleaning liquor has arrived. An example of this is polyphosphates. These can complex calcium and magnesium ions contained in the water and thereby contribute to the fact that a softening of the water does not have to be carried out separately (for example by salt addition in the dishwasher).
Weiter bevorzugt sind erfindungsgemäß Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen, deren Dichte - abhängig von den Komponenten (z. B. des Schaums) - im Bereich von 0,8 bis 1,7 g/ml liegt, vorzugsweise im Bereich von 0,9 bis 1,5 g/ml liegt. Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen mit einer derartigen Dichte können kostengünstig hergestellt werden, da preiswert zur Verfügung stehende Gase oder Gasgemische ansonsten zu verwendende Lösungsmittel als Füllstoff ersetzen können. Die resultierenden, relativ großen Volumina der so hergestellten Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen haben darüber hinaus noch den weiteren Vorteil, daß dem gesetzlichen Erfordernis Rechnung getragen wird, derartige Formkörper in einer Größe herzustellen, daß ein Verschlucken der Portionen durch Kinder unmöglich ist.Detergent, detergent or detergent portions whose density, depending on the components (eg of the foam), is in the range from 0.8 to 1.7 g / ml, preferably in the range from 0, are also preferred according to the invention , 9 to 1.5 g / ml. Detergent, detergent or detergent portions with such a density can be produced inexpensively, since inexpensive available gases or gas mixtures can replace otherwise used solvents as a filler. The resulting, relatively large volumes of the detergent, detergent or detergent portions thus prepared have the further advantage that the legal requirement is taken into account to produce such tablets in a size that swallowing the portions by children is impossible ,
Die erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen können in einer weiteren bevorzugten Ausführungsform noch einen oder mehrere weitere(n) waschaktive(n), spülaktive(n) oder reinigungsaktive(n) Komponente(n) enthalten. Unter dem Begriff "waschaktive Komponente" oder "spülaktive Komponente" oder "reinigungsaktive Komponente" werden im Rahmen der vorliegenden Erfindung Zubereitungen aller denkbaren, im Zusammenhang mit einem Wasch-, Spül- oder Reinigungsvorgang relevanten Substanzen verstanden. Dies sind in erster Linie die eigentlichen Waschmittel, Spülmittel oder Reinigungsmittel mit ihren im weiteren Verlauf der Beschreibung näher erläuterten Einzelkomponenten. Darunter fallen Aktivstoffe wie die oben näher beschriebenen Tenside (anionische, nicht-ionische, kationische und amphotere Tenside), Buildersubstanzen (anorganische und organische Buildersubstanzen), Bleichmittel (wie beispielsweise Peroxo-Bleichmittel und Chlor-Bleichmittel), Bleichaktivatoren, Bleichstabilisatoren, Bleichkatalysatoren, Enzyme, spezielle Polymere (beispielsweise solche mit Cobuilder-Eigenschaften), Vergrauungsinhibitoren, Farbstoffe und Duftstoffe (Parfums), ohne daß die Begriffe auf diese Substanzgruppen beschränkt sind.In a further preferred embodiment, the detergent, detergent or cleaner portions according to the invention may also contain one or more further wash-active, rinse-active or cleaning-active component (s). In the context of the present invention, the term "wash-active component" or "rinse-active component" or "cleansing-active component" is understood to mean all conceivable substances which are relevant in connection with a washing, rinsing or cleaning process. These are primarily the actual detergents, dishwashing detergents or cleaning agents with their individual components explained in the further course of the description. These include active ingredients such as the surfactants (anionic, nonionic, cationic and amphoteric surfactants) described above, builders (inorganic and organic builders), bleaches (such as peroxy bleach and chlorine bleach), bleach activators, bleach stabilizers, bleach catalysts, enzymes , special polymers (for example those with cobuilder properties), grayness inhibitors, dyes and fragrances (perfumes), without the terms being restricted to these substance groups.
Es werden unter dem Begriff "waschaktive Komponenten", "spülaktive Komponenten" oder "reinigungsaktive Komponenten" jedoch auch Waschhilfsmittel, Spülhilfsmittel oder Reinigungshilfsmittel verstanden. Beispiele für diese sind optische Aufheller, UV-Schutzsubstanzen, sog. Soil Repellents, also Polymere, die einer Wiederanschmutzung von Fasern oder harten Oberflächen entgegenwirken, sowie Silberschutzmittel. Auch Wäsche-Behandlungsmittel wie Weichspüler bzw. Geschirrspülmittel-Zusätze wie Klarspüler werden erfindungsgemäß als "waschaktive Komponenten", "spülaktive Komponenten" oder "reinigungsaktive Komponenten" betrachtet.However, the term "washing-active components", "rinse-active components" or "cleaning-active components" are also understood to mean washing auxiliaries, rinse aids or cleaning auxiliaries. Examples of these are optical brighteners, UV protective substances, so-called soil repellents, ie polymers which counteract re-soiling of fibers or hard surfaces, and silver protectants. Laundry-treating agents, such as fabric softeners or dishwashing detergent additives, such as rinse aids, are also considered according to the invention as "wash-active components", "rinse-active components" or "cleaning-active components".
Die in den erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen verwendbaren Tenside wurden bereits oben im Detail beschrieben.The surfactants which can be used in the detergent, dishwashing or cleaning agent portions according to the invention have already been described in detail above.
Neben den Tensiden sind Gerüststoffe die wichtigsten Inhaltsstoffe von Wasch- und Reinigungsmitteln. In den erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen können üblicherweise in Wasch- und Reinigungsmitteln eingesetzte Gerüststoffe enthalten sein, insbesondere also Zeolithe, Silicate, Carbonate, organische Cobuilder und - wo keine ökologischen Vorurteile gegen ihren Einsatz bestehen - auch Phosphate.In addition to the surfactants, builders are the most important ingredients of detergents and cleaners. In the detergent, detergent or cleaner portions according to the invention builders usually used in detergents and cleaning agents may be present, in particular zeolites, silicates, carbonates, organic cobuilders and - where there are no ecological prejudices against their use - also phosphates.
Geeignete kristalline, schichtförmige Natriumsilicate besitzen die allgemeine Formel NaMSixO2x+1 .H2O, wobei M Natrium oder Wasserstoff bedeutet, x eine Zahl von 1,9 bis 4 und y eine Zahl von 0 bis 20 ist und bevorzugte Werte für x 2, 3 oder 4 sind. Derartige kristalline Schichtsilicate werden beispielsweise in der europäischen Patentanmeldung
Einsetzbar sind auch amorphe Natriumsilicate mit einem Modul Na2O :SiO2 von 1 : 2 bis 1 : 3,3, vorzugsweise von 1 : 2 bis 1 : 2,8 und insbesondere von 1 : 2 bis 1 : 2,6, welche löseverzögert sind und Sekundärwascheigenschaften aufweisen. Die Löseverzögerung gegenüber herkömmlichen amorphen Natriumsilicaten kann dabei auf verschiedene Weise, beispielsweise durch Oberflächenbehandlung, Compoundierung, Kompaktierung/Verdichtung oder durch Übertrocknung hervorgerufen worden sein. Im Rahmen dieser Erfindung wird unter dem Begriff "amorph" auch "röntgenamorph" verstanden. Dies heißt, daß die Silicate bei Röntgenbeugungsexperimenten keine scharfen Röntgenreflexe liefern, wie sie für kristalline Substanzen typisch sind, sondern allenfalls ein oder mehrere Maxima der gestreuten Röntgenstrahlung, die eine Breite von mehreren Gradeinheiten des Beugungswinkels aufweisen. Es kann jedoch sehr wohl sogar zu besonders guten Buildereigenschaften führen, wenn die Silicatpartikel bei Elektronenbeugungsexperimenten verwaschene oder sogar scharfe Beugungsmaxima liefern. Dies ist so zu interpretieren, daß die Produkte mikrokristalline Bereiche der Größe 10 bis einige Hundert nm aufweisen, wobei Werte bis max. 50 nm und insbesondere bis max. 20 nm bevorzugt sind. Derartige sogenannte röntgenamorphe Silicate, welche ebenfalls eine Löseverzögerung gegenüber den herkömmlichen Wassergläsern aufweisen, werden beispielsweise in der deutschen Patentanmeldung
Ein gegebenenfalls eingesetzter feinkristalliner, synthetischer und gebundenes Wasser enthaltender Zeolith ist vorzugsweise Zeolith A und/oder P. Als Zeolith des P-Typs wird Zeolith MAP (z. B. Handelsprodukt: Doucil A24 der Firma Crosfield) besonders bevorzugt. Geeignet sind jedoch auch Zeolith X sowie Mischungen aus A, X und/oder P. Kommerziell erhältlich und im Rahmen der vorliegenden Erfindung bevorzugt einsetzbar ist beispielsweise auch ein Co-Kristallisat aus Zeolith X und Zeolith A (ca. 80 Gew.-% Zeolith X), das von der Firma CONDEA Augusta S.p.A. unter dem Markennamen VEGOBOND AX® vertrieben wird und durch die Formel
nNa2O·(1-n)K2O·Al2O3·(2-2,5)SiO2·(3,5-5,5)H2O
beschrieben werden kann. Geeignete Zeolithe weisen eine mittlere Teilchengröße von weniger als 10 µm (Volumenverteilung; Meßmethode: Coulter Counter) auf und enthalten vorzugsweise 18 bis 22 Gew.-%, insbesondere 20 bis 22 Gew.-% an gebundenem Wasser.A fine crystalline, synthetic and bound water-containing zeolite optionally used is preferably zeolite A and / or P. Zeolite MAP (eg, commercial product: Doucil A24 from Crosfield) is particularly preferred as the P-type zeolite. 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
nNa 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. Suitable zeolites have 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.
Selbstverständlich ist in den erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen auch ein Einsatz der allgemein bekannten Phosphate als Buildersubstanzen möglich, sofern ein derartiger Einsatz nicht aus ökologischen Gründen vermieden werden sollte. Geeignet sind insbesondere die Natriumsalze der Orthophosphate, der Pyrophosphate und insbesondere der Tripolyphosphate.Of course, in the detergents, dishwashing or cleaning agent portions according to the invention, it is also possible to use the generally known phosphates as builders, if such use should not be avoided for ecological reasons. Particularly suitable are the sodium salts of orthophosphates, pyrophosphates and in particular tripolyphosphates.
Brauchbare organische Gerüstsubstanzen sind beispielsweise die in Form ihrer Natriumsalze einsetzbaren Polycarbonsäuren, wobei unter Polycarbonsäuren solche Carbonsäuren verstanden werden, die mehr als eine Säurefunktion tragen. Beispielsweise sind dies Citronensäure, Adipinsäure, Bernsteinsäure, Glutarsäure, Äpfelsäure, Weinsäure, Maleinsäure, Fumarsäure, Zuckersäuren, Aminocarbonsäuren, Nitrilotriessigsäure (NTA), sofern deren Einsatz aus ökologischen Gründen nicht zu beanstanden ist, sowie Mischungen aus diesen. Bevorzugte Salze sind die Salze der Polycarbonsäuren wie Citronensäure, Adipinsäure, Bernsteinsäure, Glutarsäure, Weinsäure, Zuckersäuren und Mischungen aus diesen. Auch die Säuren an sich können eingesetzt werden. Die Säuren besitzen neben ihrer Builderwirkung typischerweise auch die Eigenschaft einer Säuerungskomponente und dienen somit auch zur Einstellung eines niedrigeren und milderen pH-Wertes von Wasch- und Reinigungsmittel-Portionen gemäß der Erfindung. Insbesondere sind in diesem Zusammenhang Citronensäure, Bernsteinsäure, Glutarsäure, Adipinsäure, Gluconsäure und beliebige Mischungen von diesen zu nennen.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), provided their 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 washing and cleaning agent portions according to the invention. In particular, citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures of these are to be mentioned in this context.
Als Builder sind weiter polymere Polycarboxylate geeignet. Dies sind beispielsweise die Alkalimetallsalze der Polyacrylsäure oder der Polymethacrylsäure, beispielsweise solche mit einer relativen Molekülmasse von 500 bis 70.000 g/mol.As builder further polymeric polycarboxylates are suitable. These are, for example, the alkali metal salts of polyacrylic acid or polymethacrylic acid, for example those having a molecular weight of 500 to 70,000 g / mol.
Bei den für polymere Polycarboxylate angegebenen Molmassen handelt es sich im Rahmen der vorliegenden Erfindung um gewichtsmittlere Molmassen Mw der jeweiligen Säureform, die grundsätzlich mittels Gelpermeationschromatographie (GPC) bestimmt wurden, wobei ein UV-Detektor eingesetzt wurde. Die Messung erfolgte dabei gegen einen externen Polyacrylsäure-Standard, der aufgrund seiner strukturellen Verwandtschaft mit den untersuchten Polymeren realistische Molgewichtswerte liefert. Diese Angaben weichen deutlich von den Molgewichtsangaben ab, bei denen Polystyrolsulfonsäuren als Standard eingesetzt werden. Die gegen Polystyrolsäuren gemessenen Molmassen sind in der Regel deutlich höher als die im Rahmen der vorliegenden Erfindung angegebenen Molmassen.In the context of the present invention, 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 polystyrene acids are generally significantly higher than the molecular weights specified in the context of the present invention.
Geeignete Polymere sind insbesondere Polyacrylate, die bevorzugt eine Molmasse von 2.000 bis 20.000 g/mol aufweisen. Aufgrund ihrer überlegenen Löslichkeit können aus dieser Gruppe wiederum die kurzkettigen Polyacrylate bevorzugt sein, die Molmassen von 2.000 bis 10.000 g/mol, besonders bevorzugt von 3.000 bis 5.000 g/mol, aufweisen.Suitable polymers are in particular polyacrylates, which preferably have a molecular weight of 2,000 to 20,000 g / mol. Due to their superior solubility, this group can again be the short-chain polyacrylates be preferred, the molecular weights of 2,000 to 10,000 g / mol, more preferably from 3,000 to 5,000 g / mol, have.
Geeignet sind weiterhin copolymere Polycarboxylate, insbesondere solche der Acrylsäure mit Methacrylsäure oder der Acrylsäure oder Methacrylsäure mit Maleinsäure. Als besonders geeignet haben sich Copolymere der Acrylsäure mit Maleinsäure erwiesen, die 50 bis 90 Gew.-% Acrylsäure und 50 bis 10 Gew.-% Maleinsäure enthalten. Ihre relative Molmasse, bezogen auf freie Säuren, beträgt im allgemeinen 2.000 bis 70.000 g/mol, vorzugsweise 20.000 bis 50.000 g/mol und insbesondere 30.000 bis 40.000 g/mol.Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid or 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.

The builder used here is preferably HEDP from the class of phosphonates. The aminoalkanephosphonates also have a pronounced heavy metal binding capacity. Accordingly, it may be preferred, especially when the detergent, detergent or cleaner portions according to the invention also contain bleach, to use Aminoalkanphosphonate, in particular DTPMP, or to use mixtures of said phosphonates.
Darüber hinaus können alle Verbindungen, die in der Lage sind, Komplexe mit Erdalkalimetallionen zu bilden, als Co-Builder eingesetzt werden.In addition, all compounds capable of forming complexes with alkaline earth metal ions can be used as co-builders.

Zusätzlich zu den konventionellen Bleichaktivatoren oder an deren Stelle können auch sogenannte Bleichkatalysatoren in die Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen gemäß der Erfindung eingearbeitet werden. Bei diesen Stoffen handelt es sich um bleichverstärkende Übergangsmetallsalze bzw. Übergangsmetallkomplexe wie beispielsweise Mn-, Fe-, Co-, Ru - oder Mo-Salenkomplexe oder -carbonylkomple-xe.

Als Enzyme kommen solche aus der Klasse der Proteasen, Lipasen, Amylasen, Cellulasen bzw. deren Gemische in Frage. Besonders gut geeignet sind aus Bakterienstämmen oder Pilzen, wie Bacillus subtilis, Bacillus licheniformis und Streptomyces griseus gewonnene enzymatische Wirkstoffe. Vorzugsweise werden Proteasen vom Subtilisin-Typ und insbesondere Proteasen, die aus Bacillus lentus gewonnen werden, eingesetzt. Dabei sind Enzymmischungen, beispielsweise aus Protease und Amylase oder Protease und Lipase oder Protease und Cellulase oder aus Cellulase und Lipase oder aus Protease, Amylase und Lipase oder Protease, Lipase und Cellulase, insbesondere jedoch Cellulase-haltige Mischungen von besonderem Interesse. Auch Peroxidasen oder Oxidasen haben sich in einigen Fällen als geeignet erwiesen. Die Enzyme können an Trägerstoffen adsorbiert und/oder in Hüllsubstanzen eingebettet sein, um sie gegen vorzeitige Zersetzung zu schützen. Der Anteil der Enzyme, Enzymmischungen oder Enzymgranulate in den erfindungsgemäßen Zusammensetzungen kann beispielsweise etwa 0,1 bis 5 Gew.-%, vorzugsweise 0,1 bis etwa 2 Gew.-% betragen.Suitable enzymes are those from the class of proteases, lipases, amylases, cellulases or mixtures thereof. Particularly suitable are bacterial strains or fungi, such as Bacillus subtilis, Bacillus licheniformis and Streptomyces griseus derived enzymatic agents. Preferably, subtilisin-type proteases and in particular proteases derived from Bacillus lentus are used. These are enzyme mixtures, for example from protease and amylase or protease and lipase or protease and cellulase or from cellulase and lipase or from protease, amylase and lipase or protease, lipase and cellulase, but in particular cellulase-containing Mixtures of particular interest. Peroxidases or oxidases have also proved suitable in some cases. The enzymes may be adsorbed to carriers and / or embedded in encapsulants to protect against premature degradation. The proportion of the enzymes, enzyme mixtures or enzyme granules in the compositions according to the invention can be, for example, about 0.1 to 5% by weight, preferably 0.1 to about 2% by weight.
Enzyme werden nach dem Stand der Technik in erster Linie einer Reinigungsmittel-Zubereitung zugesetzt, insbesondere einem Geschirrspülmittel zugesetzt, das für den Hauptspülgang bestimmt ist. Nachteil war dabei, daß das Wirkungsoptimum verwendeter Enzyme die Temperaturwahl beschränkte und auch Probleme bei der Stabilität der Enzyme im stark alkalischen Milieu auftraten. Mit den erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen ist es möglich, Enzyme auch im Vorspülgang zu verwenden und damit den Vorspülgang zusätzlich zum Hauptspülgang für eine Enzymeinwirkung auf Verschmutzungen des Spülguts zu nutzen.Enzymes are added according to the prior art primarily to a detergent composition, in particular a dishwashing agent, which is intended for the main rinse. Disadvantage was that the optimum effect of enzymes used limited the choice of temperature and also encountered problems in the stability of the enzymes in a strongly alkaline medium. With the detergent, detergent or cleaner portions according to the invention, it is possible to use enzymes in the pre-wash and thus to use the pre-rinse cycle in addition to the main rinse for an enzyme action on contaminants of the dishes.
Erfindungsgemäß besonders bevorzugt ist also, der für den Vorspülgang vorgesehenen waschaktiven Zubereitung oder Teilportion einer Reinigungsmittel-Portion Enzyme zuzusetzen. Die Enzyme sind weiter bevorzugt für den Einsatz unter den Bedingungen des Vorspülgangs, also beispielsweise in kaltem Wasser, optimiert.It is therefore particularly preferred according to the invention to add enzymes to the detergent-active preparation or partial portion of a detergent portion intended for the pre-wash cycle. The enzymes are more preferably optimized for use under the conditions of the pre-wash cycle, that is, for example, in cold water.
Vorteilhaft können die erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen dann sein, wenn die Enzymzubereitungen flüssig vorliegen, wie sie teilweise im Handel angeboten werden, weil dann eine schnelle Wirkung erwartet werden kann, die bereits im (relativ kurzen und in kaltem Wasser durchgeführten) Vorspülgang eintritt. Auch wenn - wie üblich - die Enzyme in fester Form eingesetzt werden und diese mit einer Umhüllung aus einem wasserlöslichen Material versehen sind, das bereits in kaltem Wasser löslich ist, können die Enzyme bereits vor dem Hauptwaschgang bzw. Hauptreinigungsgang ihre Wirkung entfalten. Vorteil der Verwendung einer Umfassung aus wasserlöslichem Material, insbesondere aus kaltwasserlöslichem Material ist, daß das Enzym/die Enzyme in kaltem Wasser nach Auflösen der Umfassung schnell zur Wirkung kommt/kommen. Damit kann deren Wirkungszeit ausgedehnt werden, was dem Wasch- bzw. Spülergebnis zugute kommt.Advantageously, the detergent, detergent or cleaner portions according to the invention can then be when the enzyme preparations are liquid, as they are sometimes available commercially, because then a rapid effect can be expected, already in (relatively short and carried out in cold water ) Pre-rinse occurs. Even if - as usual - the enzymes are used in solid form and they are provided with a sheath of a water-soluble material that is already soluble in cold water, the enzymes can unfold their effect even before the main wash or Hauptreinigungsgang. Advantage of the use of an enclosure of water-soluble material, in particular of cold water-soluble material is that the enzyme / enzymes in cold water after dissolution of the enclosure comes to effect quickly / come. Thus, their duration of action can be extended, which benefits the washing or rinsing results.

Beispiele für optische Aufheller sind Derivate von Diaminostilbendisulfonsäure bzw. deren Alkalimetallsalze. Geeignet sind z. B. Salze der 4, 4'-Bis(2-anilino-4-morpholino1,3,5-triazinyl-6-amino)stilben-2,2'-disulfonsäure oder gleichartig aufgebaute Verbindungen, die anstelle der Morpholino-Gruppe eine Diethanolamino-Gruppe, eine Methylamino-Gruppe, eine Anilino-Gruppe oder eine 2-Methoxyethylamino-Gruppe tragen. Weiterhin können Aufheller vom Typ der substituierten Diphenylstyryle in den Teil-Portionen (waschaktiven Zubereitun-gen) der erfindungsgemäßen Wasch- oder Reinigungsmittel-Portionen enthalten sein, z. B. die Alkalisalze des 4,4'-Bis(2-sulfostyryl-)diphenyls, 4,4'-Bis(4-chlor-3-sulfostyryl-)diphenyls oder 4-(4-Chlorstyryl-)4'-(2-sulfostyryl-)diphenyls. Auch Gemische der vorgenannten Aufheller können verwendet werden.A preferred group of additives used in the invention are optical brighteners. Can be used here, the usual in detergents optical brightener. These are added to the polymer solution as an aqueous solution or as a solution in an organic solvent, which is converted into the film, or are added to a TeilPortion (detergent preparation) a detergent, detergent or cleaning agent portion in solid or liquid form. Examples of optical brighteners are derivatives of diaminostilbene disulfonic acid or its alkali metal salts. Suitable z. B. salts of 4, 4'-bis (2-anilino-4-morpholino1,3,5-triazinyl-6-amino) stilbene-2,2'-disulfonic acid or compounds of similar construction, which instead of the morpholino group Diethanolamino Group, a methylamino group, an anilino group or a 2-methoxyethylamino group. Furthermore, brighteners of the type of substituted diphenylstyrene may be present in the partial portions (washing-active preparations) of the washing or cleaning agent portions according to the invention, eg. For example, the alkali salts of 4,4'-bis (2-sulfostyryl) diphenyl, 4,4'-bis (4-chloro-3-sulfostyryl) diphenyl or 4- (4-chlorostyryl) 4 '- (2 -sulfostyryl-) biphenyl. Mixtures of the aforementioned brightener can be used.
Eine weitere erfindungsgemäß bevorzugte Gruppe von Additiven sind UV-Schutz-Substanzen. Dabei handelt es sich um Stoffe, die beim Waschprozeß oder bei dem nachfolgenden Weichspülprozeß in der Waschflotte freigesetzt werden und die sich auf der Faser akkumulativ anhäufen, um dann einen UV-Schutz-Effekt zu erzielen. Geeignet sind die unter der Bezeichnung TinosorbR im Handel befindlichen Produkte der Firma Ciba Speciality Chemicals.Another group of additives which is preferred according to the invention are UV protection substances. These are substances that are released during the washing process or in the subsequent fabric softening process in the wash liquor and that accumulate accumulatively on the fiber, in order then to achieve a UV protection effect. Suitable are the products marketed under the name Tinosorb R Ciba Specialty Chemicals.
Weitere denkbare und in speziellen Ausführungsformen bevorzugte Additive sind Tenside, die insbesondere die Löslichkeit der wasserlöslichen Folie beeinflussen können, aber auch deren Benetzbarkeit und die Schaumbildung beim Auflösen steuern können, sowie Schauminhibitoren, aber auch Bitterstoffe, die ein versehentliches Verschlucken solcher Verpackungen oder Teile solcher Verpackungen von Kindern verhindern können.Further conceivable additives, which are preferred in specific embodiments, are surfactants which in particular can influence the solubility of the water-soluble film, but can also control its wettability and foaming on dissolution, as well as foam inhibitors, but also bitter substances, which may inadvertently swallow such packaging or parts of such packaging prevent from children.
Eine weitere erfindungsgemäß bevorzugte Gruppe von Additiven sind Farbstoffe, insbesondere wasserlösliche oder wasserdispergierbare Farbstoffe. Bevorzugt sind hier Farbstoffe, wie sie zur Verbesserung der optischen Produktanmutung in Wasch- und Reinigungsmitteln üblicherweise eingesetzt werden. Die Auswahl derartiger Farbstoffe bereitet dem Fachmann keine Schwierigkeiten, insbesondere da derartige übliche Farbstoffe eine hohe Lagerstabilität und Unempfindlichkeit gegenüber den übrigen Inhaltsstoffen der Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen und gegen Licht sowie keine ausgeprägte Substantivität gegenüber Textilfasern haben, um diese nicht anzufärben. Die Farbstoffe sind erfindungsgemäß in den Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen in Mengen von unter 0,01 Gew.-% zugegen.Another group of additives which is preferred according to the invention are dyes, in particular water-soluble or water-dispersible dyes. Dyes which are customarily used to improve the appearance of the optical product in detergents and cleaners are preferred here. The selection of such dyes is not difficult for a person skilled in the art, especially since such conventional dyes have a high storage stability and insensitivity to the other ingredients of the detergent, detergent or cleaning agent portions and to light and no pronounced substantivity to textile fibers to not stain them. The dyes according to the invention in the detergent, detergent or detergent portions in amounts of below 0.01 wt .-% present.
Eine weitere Klasse von Additiven, die erfindungsgemäß den Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen zugesetzt werden kann, sind Polymere. Unter diesen Polymeren kommen zum einen Polymere in Frage, die beim Waschen oder Reinigen bzw. Spülen Cobuilder-Eigenschaften zeigen, also zum Beispiel Polyacrylsäuren, auch modifizierte Polyacrylsäuren oder entsprechende Copolymere. Eine weitere Gruppe von Polymeren sind Polyvinylpyrrolidon und andere Vergrauungsinhibitoren, wie Copolymere von Polyvinylpyrrolidon, Cellulose-Ether und dergleichen. Nach einer weiteren Ausführungsform der Erfindung kommen als Polymere auch sogenannte Soil Repellents in Frage, wie sie dem Wasch- und Reinigungsmittel-Fachmann bekannt sind und nachfolgend im einzelnen beschrieben werden.Another class of additives which may be added to the detergent, rinse or detergent portions in accordance with the invention are polymers. Among these polymers are on the one hand polymers in question, which show washing or cleaning or rinsing Cobuilder properties, so for example polyacrylic acids, and modified polyacrylic acids or corresponding copolymers. Another group of polymers are polyvinylpyrrolidone and other grayness inhibitors, such as copolymers of polyvinylpyrrolidone, cellulose ethers, and the like. According to a further embodiment of the invention, so-called soil repellents are also suitable as polymers, as are known to the washing and cleaning agent specialist and will be described in detail below.
Eine weitere Gruppe von Additiven sind Bleichkatalysatoren, insbesondere Bleichkatalysatoren für maschinelle Geschirrspülmittel oder Waschmittel. Verwendet werden hier Komplexe des Mangans und des Cobalts, insbesondere mit stickstoffhaltigen Liganden.Another group of additives are bleach catalysts, in particular bleach catalysts for automatic dishwashing detergents or detergents. Here are used complexes of manganese and cobalt, especially with nitrogen-containing ligands.
Eine weitere im Sinne der Erfindung bevorzugte Gruppe von Additiven sind Silberschutzmittel. Es handelt sich hier um eine Vielzahl von meist cyclischen organischen Verbindungen, die ebenfalls dem hier angesprochen Fachmann geläufig sind und dazu beitragen, das Anlaufen von Silber enthaltenden Gegenständen beim Reinigungsprozeß zu verhindern. Spezielle Beispiele können Triazole, Benzotriazole und deren Komplexe mit Metallen wie beispielsweise Mn, Co, Zn, Fe, Mo, W oder Cu sein.Another preferred group of additives within the meaning of the invention are silver protectants. These are a variety of mostly cyclic organic compounds, which are also familiar to the person skilled in the art and contribute to prevent the tarnishing of silver-containing objects in the cleaning process. Specific examples may be triazoles, benzotriazoles and their complexes with metals such as Mn, Co, Zn, Fe, Mo, W or Cu.
Als weitere erfindungsgemäße Zusätze können die Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen auch sogenannte Soil Repellents enthalten, also Polymere, die auf Fasern oder harte Flächen (beispielsweise auf Porzellan und Glas) aufziehen, die Öl- und Fettauswaschbarkeit aus Textilien positiv beeinflussen und damit einer Wiederanschmutzung gezielt entgegenwirken. Dieser Effekt wird besonders deutlich, wenn ein Textil oder ein harter Gegenstand (Porzellan, Glas) verschmutzt wird, das/der bereits vorher mehrfach mit einer erfindungsgemäßen Portion, das diese öl- und fettlösende Komponente enthält, gewaschen oder gereinigt wurde. Zu den bevorzugten öl- und fettlösenden Komponenten zählen beispielsweise nichtionische Celluloseether wie Methylcellulose und Methylhydroxypropylcellulose mit einem Anteil an Methoxy-Gruppen von 15 bis 30 Gew.-% und an Hydroxypropoxy-Gruppen von 1 bis 15 Gew.-%, jeweils bezogen auf den nichtionischen Celluloseether, sowie die aus dem Stand der Technik bekannten Polymere der Phthalsäure und/oder der Terephthalsäure bzw. von deren Derivaten, insbesondere Polymere aus Ethylenterephthalaten und/oder Polyethylenglykolterephthalaten oder anionisch und/oder nichtionisch modifizierten Derivaten von diesen. Besonders bevorzugt von diesen sind die sulfonierten Derivate der Phthalsäure- und der Terephthalsäure-Polymere.As further additives according to the invention, the detergent, detergent or cleaning agent portions may also contain so-called soil repellents, ie polymers which are applied to fibers or hard surfaces (for example on porcelain and glass), have a positive effect on the oil and grease washability of textiles and thus specifically counteract re-soiling. This effect becomes particularly evident when a textile or a hard object (porcelain, glass) is contaminated, which has already been washed or cleaned several times with a portion according to the invention which contains this oil and fat-dissolving component. Examples of preferred oil and fat dissolving components include nonionic cellulose ethers such as methylcellulose and methylhydroxypropylcellulose with a methoxy group content of 15 to 30% by weight and of hydroxypropoxy groups of 1 to 15% by weight, based in each case on the nonionic Cellulose ethers, as well as 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. Particularly preferred of these are the sulfonated derivatives of phthalic and terephthalic acid polymers.
Alle diese Additive werden den erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen in Mengen bis höchstens 30 Gew.-%, vorzugsweise 2 bis 20 Gew.-%, zugesetzt. Wie bereits gesagt, kann der Zusatz auch zu einem Material einer wasserlöslichen Umfassung erfolgen, das die oder eine der waschaktive(n) Zubereitung(en) umfaßt. Um die Ausgewogenheit der Rezeptur zu erhalten, ist es dem Fachmann daher möglich, das Kunststoffmaterial für die Umfassung entweder in seinem Gewicht zu steigern, um so den Depot-Effekt der gemäß Erfindung erzielt wird, auszunutzen oder aber die genannten Additive zusätzlich zumindest anteilsweise in der restlichen Portion zu halten. Dies ist jedoch weniger bevorzugt.All of these additives are added to the inventive detergent, detergent or cleaner portions in amounts of at most 30 wt .-%, preferably 2 to 20 wt .-%. As already stated, the addition can also be made to a material of a water-soluble enclosure comprising the or one of the detergent-active preparation (s). To obtain the balance of the recipe, it is therefore possible for the skilled person to increase the plastic material for the enclosure either in its weight so as to achieve the depot effect of the invention, exploit or additionally said additives at least partially in the to keep the remaining portion. However, this is less preferred.
Duftstoffe werden den erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen zugesetzt, um den ästhetischen Gesamteindruck der Produkte zu verbessern und dem Verbraucher neben der technischen Leistung (Weichspülergebnis) ein sensorisch typisches und unverwechselbares Produkt zur Verfügung zu stellen. Als Parfümöle oder Duftstoffe können einzelne Riechstoff-Verbindungen verwendet werden, beispielsweise die synthetischen Produkte vom Typ der Ester, Ether, Aldehyde, Ketone, Alkohole und Kohlenwasserstoffe. Riechstoff-Verbindungen vom Typ der Ester sind beispielsweise Benzyl-acetat, Phenoxyethylisobutyrat, p-t-Butylcyclohexylacetat, Linalylacetat, Dimethylbenz-ylcarbinylacetat, Phenylethylacetat, Linalylbenzoat, Benzylformiat, Ethylmethylphenylglycinat, Allylcyclohexylpropionat, Styrallylpropionat und Benzylsalicylat. Zu den Ethern zählen beispielsweise Benzylethylether. Zu den Aldehyden zählen z. B. lineare Alkanale mit 8 bis 18 C-Atomen, Citral, Citronellal, Citronellyloxyacetaldehyd, Cyclamenaldehyd, Hydroxycitronellal, Lileal und Bourgeonal.Fragrances are added to the detergent, detergent or cleaner portions according to the invention in order to improve the aesthetic overall impression of the products and to provide the consumer in addition to the technical performance (fabric softening result) a sensory typical and distinctive product. As perfume oils or perfumes, individual perfume compounds can be used, for example the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-t-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate, phenylethylacetate, linalylbenzoate, benzylformate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and benzylsalicylate.

Üblicherweise liegt der Gehalt an Duftstoffen im Bereich bis zu 2 Gew.-% der gesamten Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion.Usually, the content of perfumes in the range up to 2 wt .-% of the total detergent, detergent or detergent portion.
Die Duftstoffe können direkt in die Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen eingearbeitet werden; es kann aber auch vorteilhaft sein, die Duftstoffe auf Träger aufzubringen, die die Haftung des Parfüms auf der Wäsche verstärken und durch eine langsamere Duftfreisetzung für langanhaltenden Duft der Textilien sorgen. Als solche Trägermaterialien haben sich beispielsweise Cyclodextrine bewährt. Dabei können die Cyclodextrin-Parfüm-Komplexe zusätzlich noch mit weiteren Hilfsstoffen beschichtet werden.The fragrances can be incorporated directly into the detergent, detergent or detergent portions become; but it may also be advantageous to apply the fragrances on carriers that enhance the adhesion of the perfume on the laundry and provide by a slower release of fragrance for long-lasting fragrance of the textiles. As such carrier materials, for example, cyclodextrins have been proven. The cyclodextrin-perfume complexes can additionally be coated with other auxiliaries.
Die Parfüm- und Duftstoffe können grundsätzlich in jeder der Teil-Portionen (waschaktive Zubereitungen) der erfindungsgemäßen Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen enthalten sein. Besonders bevorzugt ist es jedoch, daß sie in einem Waschmittel in einer für den Nachwaschgang oder Weichspülgang vorgesehenen Teil-Waschmittel-Portion bzw. in einem Reinigungsmittel, besonders in einem Geschirrspülmittel, in einer für den Nachspülgang bzw. Klarspülgang vorgesehenen Teil-Reinigungsmittel-Portion, speziell Teil-Spülmittel-Portion, enthalten sind. Sie müssen daher erfindungsgemäß von einem nur bei den Bedingungen (insbesondere bei der Temperatur) des Nachwaschgangs bzw. Nachspülgangs wasserlöslichen, bei den Bedingungen (insbesondere bei der Temperatur) der vorangehenden Waschgänge bzw. Spülgänge wasserunlöslichen Material, insbesondere von einer entsprechenden Folie oder Kapsel umfaßt sein. Erfindungsgemäß ist dies beispielsweise mit einem aus mehreren Kammern bestehenden Beutel aus Folien unterschiedlicher Wasserlöslichkeit machbar.The perfumes and fragrances can in principle be contained in each of the partial portions (washing-active preparations) of the detergent, dishwashing or cleaning agent portions according to the invention. However, it is particularly preferred that they are in a detergent in a provided for the post-wash cycle or fabric conditioning portion detergent portion or in a detergent, especially in a dishwashing detergent, in a provided for the final rinse or rinse cycle part-detergent portion, special partial-detergent portion, are included. They must therefore according to the invention of a water-insoluble only in the conditions (especially at the temperature) of the Nachwaschgangs or Nachspülgangs, under the conditions (especially at the temperature) of the previous washes or rinses water-insoluble material, in particular of a corresponding film or capsule , According to the invention this is feasible, for example, with a bag consisting of several chambers made of films of different water solubility.
Gemäß zwei weiteren bevorzugten Ausführungsformen der Erfindung werden Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen mit einem in Innern der in Wasser desintegrierbaren Umhüllung herrschenden Druck des aufschäumenden Gases/der aufschäumenden Gase geschaffen, der mindestens gleich dem Atmosphärendruck ist, der jedoch - weiter bevorzugt - größer als Atmosphärendruck ist. Damit wird in vorteilhafter Weise ermöglicht, daß ein Eindringen von Feuchtigkeit in das Innere der Umhüllung erschwert wird und die im Innern enthaltenen Komponenten der Portion besser vor einem schädigenden Einfluß geschützt ist. Dies kann in einer alternativen Ausführungsform der Erfindung auch erreicht werden, indem man eine oder mehrere in der Waschmittel-, Spülmittel- oder Reinigungsmittel-Portion enthaltene Komponenten, die in Gefahr sind, in Gegenwart von Feuchtigkeit einem teilweisen oder vollständigen Aktivitätsverlust zu unterliegen, vor dem Zutritt von Wasser oder Feuchtigkeit durch ein Coating schützt.According to two further preferred embodiments of the invention detergent, detergent or detergent portions are provided with a pressure of the foaming gas / foaming gases which is at least equal to the atmospheric pressure, inside the water-disintegratable casing. is greater than atmospheric pressure. This advantageously makes it possible to prevent the penetration of moisture into the interior of the casing and to better protect the components of the portion contained in the interior from harmful influence. This can also be achieved in an alternative embodiment of the invention by subjecting one or more components contained in the detergent, rinse or detergent portion, which are in danger of undergoing a partial or complete loss of activity in the presence of moisture, before Access of water or moisture by a coating protects.
Im Hinblick auf die Notwendigkeit, die desintegrierbare Umhüllung der Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen vor einer vorzeitigen Desintegration durch Wasser zu schützen, sollte der Wassergehalt der Komponenten des Schaum-Formkörpers gemäß der Erfindung beschränkt werden. Er liegt in einer besonders bevorzugten Ausführungsform bei höchstens 15 Gew.-%, weiter bevorzugt bei 1 bis 10 Gew.-%,In view of the need to protect the disintegratable envelope of the detergent, detergent or detergent portions from premature disintegration by water, the water content of the components of the foam body according to the invention should be limited. In a particularly preferred embodiment, it is at most 15% by weight, more preferably from 1 to 10% by weight,
Bei der Herstellung der Umhüllungen der Waschmittel-, Spülmittel- oder Reinigungsmittel-Portionen kann man beispielsweise zwei Folien unterschiedlicher Zusammensetzung parallel ablaufen lassen und daraus die aus den beiden verschiedenen Materialien gebildeten Folien zusammensetzen. Die allgemeine Vorgehensweise ist als solche aus dem Stand der Technik wohlbekannt und bedarf keiner weiteren Erläuterung.In the production of the wraps of detergent, detergent or detergent portions, for example, two films of different composition can be run in parallel and composed of the films formed from the two different materials. The general procedure is well known as such from the prior art and needs no further explanation.
Besonders bevorzugt ist ein Verfahren, bei dem die Komponenten der Umhüllung nach der chemischen Synthese (Ausbildung der Bindungen wie vorstehend beschrieben) extrudiert und zu Granulaten verarbeitet werden, wofür - je nach der Temperaturstabilität der beteiligten Verbindungen - auch eine erhöhte Temperatur angewendet werden kann. Die erhaltenen Granulate werden bei Bedarf aufgeschmolzen, gegebenenfalls in Gegenwart eines Plastifiziermittels, und werden dann z. B. nach herkömmlichen, an sich bekannten Verfahren zu Schlauchbeuteln verarbeitet.Particularly preferred is a method in which the components of the envelope after the chemical synthesis (formation of the bonds as described above) are extruded and processed into granules, for which - depending on the temperature stability of the compounds involved - also an elevated temperature can be applied. The resulting granules are melted if necessary, optionally in the presence of a plasticizer, and are then z. B. processed by conventional methods known per se to tubular bags.
Eine weitere, erfindungsgemäß anwendbare Verfahrensweise ist unter der Bezeichnung "rotary die"-Verfahren bekannt. Bei diesem laufen zwei vorher hergestellte Folien, die beispielsweise die vorstehend beschriebenen Charakteristiken haben können, in einem mehr oder weniger spitzen Winkel in den Walzenspalt eines Walzenpaares, dessen Oberflächen mit z. B. halbkugelförmigen Vertiefungen versehen sind. Auf der Höhe des Walzenspaltes wird in die zusammenlaufenden Folien die Mischung aus waschaktiven, spülaktiven oder reinigungsaktiven "Inhalts-"Komponenten eingefüllt, die sich dann - in den beispielsweise halbkugelförmigen Vertiefungen - zu einer mit den Komponenten gefüllten Kugel-Portion mit einer vollständigen Umhüllung aus der Folie formen lassen. Auch dieses Verfahren ist allgemein bekannt und bedarf daher an dieser Stelle keiner weiteren Beschreibung.Another method which can be used according to the invention is known by the term "rotary die" method. In this run two previously produced films, which may for example have the characteristics described above, at a more or less acute angle in the nip of a pair of rollers whose surfaces with z. B. hemispherical depressions are provided. At the height of the nip, the mixture of wash-active, rinse-active or cleaning-active "content" components is filled in the converging films, which then - in the example hemispherical depressions - to a filled with the components spherical portion with a complete envelope of the Form foil. Also, this method is well known and therefore needs no further description at this point.
