Definitions
- the present invention relates to an agent for cleaning laundry and its use, in particular the present invention relates to an agent for cleaning laundry in a washing machine which contains surfactants and fragrances and dissolves within a rinsing process.
- Such agents for cleaning laundry in the washing machine are known in the form of washing powder or in the form of liquid detergents. With such detergents, however, the correct dosage is required.
- detergent portions that are ready to dose, so that the consumer does not need to measure.
- ready-to-dose portions are known as detergent tablets, for example in the form of compressed powder, as a capsule or as a free-flowing powder in water-soluble film, so-called pouches.
- Such ready-to-dose portions can also consist of several phases, which can differ in their composition and dissolution rate. It is thus possible to release a specific formulation at a desired point in the washing cycle during the washing process.
- solid detergent tablets which generally consist of compacted powder and are thus solid detergent tablets
- detergent tablets that contain liquid detergents.
- the liquid detergents in these detergent tablets are filled in the required amount into small bags made of dissolvable foils that dissolve during the washing process.
- Detergent tablets are also known which have several compartments filled with liquid detergent or other formulations such as powder or granules.
- a disadvantage of the liquid detergents in the film bags is that the films often do not dissolve as quickly. Another disadvantage is that the bags can leak. In order to prevent this as much as possible during transport and storage, the individual liquid detergent tablets are packed in mechanically stable packaging, which is complex, cost-intensive and not environmentally friendly.
- toilet cleaning agents refreshing the indoor air are known in pieces. These agents are transparent and cut-resistant and comprise alkane carboxylic acid salts which act as gelling agents and together with the water form cut-resistant transparent gels. The cleaning effect of these toilet blocks is low, they act as fragrances.
- alkane carboxylic acid salts frequently used in the prior art as gel formers have the disadvantage that they form calcium soaps which are sparingly soluble with calcium ions. Due to the poorly soluble precipitation, such agents cloud over time and dissolve only poorly in water. In principle, however, the reduction in the proportion of alkane carboxylic acid salts goes hand in hand with a lowering of the melting point and the hardness of the agent, for example in US 4,666,671 described, so that such cleaning agents with small amounts of alkane carboxylic acid salts already melt below 50 ° C and are therefore unsuitable for transport and storage in hotter climates or in summer.
- Bar-shaped cleaning agents for the toilet sector which comprise surfactants, 1% by weight to 5% by weight of alkane carboxylic acid salts, solvents and at least 16% by weight of nonionic surfactants from the group of block polymers comprising oligo- or polyalkylene oxides.
- These cleaning agents are transparent, cut-resistant, lump-shaped and sufficiently hard and show a melting point above 50 ° C. These agents foam and are rinsed off in the toilet after a number of flushing cycles. The cleaning performance of these agents is low.
- the EP 1 325 103 B1 teaches a viscous sanitary cleaning and scenting agent that is transparent and can be applied directly to the sanitary object, adheres there and can only be rinsed off after a large number of rinsing processes.
- the agent has an adhesion promoter, for example from the group of stearates or polyalkoxyalkanes, surfactants and water.
- a bar-shaped toilet cleaning and scenting agent which comprises alkane carboxylic acid salts, solvents, surfactants, perfume oil and sugar.
- the product is transparent and only dissolves in the toilet bowl after at least 150 rinses with cold water.
- the agents known from the sanitary agent sector are transparent and mostly in the form of pieces, they only dissolve when they are rinsed with water after more than 100 rinses and are usually not or only slightly cleaning.
- this composition is not suitable for water-soluble pouches.
- a transparent dishwasher detergent gels which contain alkane carboxylic acid salts, more than 50% by weight of nonionic surfactants, and less than 15% by weight of water.
- the composition is relatively soft.
- the object of the present invention is to provide a means for cleaning textiles which contains surfactants and possibly also fragrances which dissolve completely within a washing cycle, foam, are easy to pack and look appealing. The drug should also not run out.
- an agent for cleaning laundry which comprises surfactants and possibly also fragrances, which contains less than 5% by weight of alkane carboxylic acid salts, between 20% by weight and 60% by weight of solvent, of which at least 10% by weight of water and 10% by weight to 50% by weight of surfactants which are different from the alkane carboxylic acid salts ("other surfactants”) and 10% by weight to 70% by weight of a readily water-soluble solid organic compound which is not washable and does not form gels, with a maximum molar mass of 500 g / mol.
- the agent according to the invention is a solid gel, it is cut-resistant and transparent. It cannot leak and is easy to pack. Due to the transparency, it is also visually appealing. It also dissolves completely within one wash cycle.
- the proportion of alkane carboxylic acid salts should be below 5% by weight and preferably below 4% by weight and should be at least 0.5% by weight and preferably at least 1% by weight and particularly preferably about 3% by weight. With a higher proportion of alkane carboxylic acid salts, the cleaning agent is hard, transparent and cut-resistant, as is known from the transparent cosmetic soaps, but such an agent does not wash off in a rinsing cycle.
- the salts of aliphatic or unsaturated alkane carboxylic acids are used as salts of the alkane carboxylic acids.
- the alkane carboxylic acid salts preferably have a carbon chain with between 10 and 24 carbon atoms and are monocarboxylic acid salts, in particular alkali soaps.
- Particularly preferred alkane carboxylic acid salts are salts of stearic, lauric, myristic, palmitic, oleic acid and / or C-cuts thereof from natural or synthetic sources.

- Betaines for example, can be used as amphoteric surfactants and quaternary alkylammonium compounds as cationic surfactants. In the case of cationic surfactants, care must be taken in the selection that no cloud formation occurs due to the formation of neutral complexes.
- the cleaning agent should have no or at most only very small amounts of polymeric or higher molecular weight compounds, since these reduce the dissolution rate.
- the agent according to the invention should have a maximum of 3% by weight, preferably a maximum of 1% by weight and particularly preferably no polymers with a molecular weight of more than 5000 g / mol or more than 4000 g / mol.

The medium therefore does not change its shape under the exclusive influence of gravity.
- Another significant advantage of the present invention is that the Formulation can be filled into a PVA film and stored.
- the surfactants were melted, the sugar added and then the water added and the mixture was then allowed to cool.
- the formulations V1, V2 and V3 are transparent, hard, dimensionally stable and cut-resistant.

Description
Die vorliegende Erfindung betrifft ein Mittel zur Reinigung von Wäsche und seine Verwendung, insbesondere betrifft die vorliegende Erfindung ein Mittel zur Reinigung von Wäsche in einer Waschmaschine, das Tenside und Duftstoffe enthält und sich innerhalb eines Spülvorgangs auflöst.The present invention relates to an agent for cleaning laundry and its use, in particular the present invention relates to an agent for cleaning laundry in a washing machine which contains surfactants and fragrances and dissolves within a rinsing process.
Solche Mittel zur Reinigung von Wäsche in der Waschmaschine sind in Form von Waschpulver oder in Form von flüssigen Waschmitteln bekannt. Bei solchen Waschmitteln ist allerdings die richtige Dosierung erforderlich.Such agents for cleaning laundry in the washing machine are known in the form of washing powder or in the form of liquid detergents. With such detergents, however, the correct dosage is required.
Weiterhin gibt es Waschmittelportionen, die dosierfertig sind, so dass beim Verbraucher das Abmessen entfällt. Solche dosierfertigen Portionen sind als Waschmitteltabletten, beispielsweise in Form von komprimiertem Pulver, als Kapsel oder als freifließendes Pulver in wasserlöslicher Folie, sog. Pouches, bekannt.There are also detergent portions that are ready to dose, so that the consumer does not need to measure. Such ready-to-dose portions are known as detergent tablets, for example in the form of compressed powder, as a capsule or as a free-flowing powder in water-soluble film, so-called pouches.
Solche dosierfertigen Portionen können auch aus mehreren Phasen bestehen, die sich in ihrer Zusammensetzung und Auflösegeschwindigkeit unterscheiden können. Somit ist es möglich, während des Waschvorgangs zu einem gewünschten Zeitpunkt im Waschzyklus eine bestimmte Formulierung freizusetzen.Such ready-to-dose portions can also consist of several phases, which can differ in their composition and dissolution rate. It is thus possible to release a specific formulation at a desired point in the washing cycle during the washing process.
Neben den festen Waschmitteltabs, die im Allgemeinen aus kompaktiertem Pulver bestehen und somit feste Reinigungsmittelformkörper sind, gibt es auch Waschmitteltabletten, die Flüssigwaschmittel enthalten. Die Flüssigwaschmittel sind bei diesen Waschmitteltabs in der jeweils benötigten Menge in kleine Beutel aus auflösbaren Folien gefüllt, die sich während des Waschprozesses auflösen.In addition to the solid detergent tablets, which generally consist of compacted powder and are thus solid detergent tablets, there are also detergent tablets that contain liquid detergents. The liquid detergents in these detergent tablets are filled in the required amount into small bags made of dissolvable foils that dissolve during the washing process.
Auch Waschmitteltabletten, die mehrere mit Flüssigwaschmittel oder anderen Formulierungen wie Pulver oder Granulate gefüllte Kammern aufweisen, sind bekannt.Detergent tablets are also known which have several compartments filled with liquid detergent or other formulations such as powder or granules.
Im Allgemeinen ist das Aussehen solcher Flüssigwaschmitteltabletten ansprechend, häufig sind die unterschiedlichen Flüssigphasen transparent und unterschiedlich eingefärbt, so dass dem Verbraucher die Wirkung der verschiedenen Komponenten in den verschiedenen Waschzyklen visualisiert wird.In general, the appearance of such liquid detergent tablets is appealing, often the different liquid phases are transparent and colored differently, so that the consumer can see the effect of the different components in the different washing cycles is visualized.
Nachteilig an den Flüssigwaschmitteln in den Folienbeuteln ist jedoch, dass sich die Folien häufig nicht so schnell auflösen. Ein weiterer Nachteil besteht darin, dass die Beutel auslaufen können. Um dies während des Transports und der Lagerung soweit wie möglich zu verhindern, werden die einzelnen Flüssigwaschmitteltabs in mechanisch stabilen Verpackungen verpackt, was aufwendig, kostenintensiv und nicht umweltfreundlich ist.A disadvantage of the liquid detergents in the film bags, however, is that the films often do not dissolve as quickly. Another disadvantage is that the bags can leak. In order to prevent this as much as possible during transport and storage, the individual liquid detergent tablets are packed in mechanically stable packaging, which is complex, cost-intensive and not environmentally friendly.
Aus dem Stand der Technik sind auf dem Gebiet der Reinigungsmittel für Toiletten verschiedene optisch ansprechende Systeme bekannt.Various optically appealing systems are known from the prior art in the field of cleaning agents for toilets.

Die im Stand der Technik häufig als Gelbildner verwendeten Alkancarbonsäuresalze besitzen allerdings den Nachteil, dass sie mit Calciumionen schwerlösliche Calciumseifen bilden. Durch den schwerlöslichen Niederschlag trüben solche Mittel mit der Zeit ein und lösen sich nur schlecht in Wasser auf. Grundsätzlich geht die Reduzierung des Anteils an Alkancarbonsäuresalzen jedoch mit einer Erniedrigung des Schmelzpunktes sowie der Härte des Mittels einher, wie beispielsweise in der

Die aus dem Sanitärmittelbereich bekannten Mittel sind zwar transparent und meist stückförmig, allerdings lösen sie sich beim Überspülen mit Wasser erst nach mehr als 100 Spülungen auf und sind meist nicht oder nur geringfügig reinigend.Although the agents known from the sanitary agent sector are transparent and mostly in the form of pieces, they only dissolve when they are rinsed with water after more than 100 rinses and are usually not or only slightly cleaning.
Aufgrund des hohen Wasseranteils ist diese Zusammensetzung nicht für wasserlösliche Pouches geeignet.Due to the high water content, this composition is not suitable for water-soluble pouches.

Die Aufgabe der vorliegenden Erfindung besteht darin, ein Mittel zur Reinigung von Textilien anzugeben, das Tenside enthält und ggfs. auch Duftstoffe, das sich innerhalb eines Waschzyklus vollständig auflöst, schäumt, einfach verpackbar ist und ansprechend aussieht. Das Mittel sollte zudem nicht auslaufen.The object of the present invention is to provide a means for cleaning textiles which contains surfactants and possibly also fragrances which dissolve completely within a washing cycle, foam, are easy to pack and look appealing. The drug should also not run out.
Diese Aufgabe wird durch ein Mittel zur Reinigung von Wäsche, das Tenside und ggfs. auch Duftstoffe umfasst, gelöst, das weniger als 5 Gew.% Alkancarbonsäuresalze, zwischen 20 Gew.% und 60 Gew.% Lösemittel, wovon mindestens 10 Gew.% Wasser sind, und 10 Gew.% bis 50 Gew.% Tenside umfasst, die von den Alkancarbonsäuresalzen verschieden sind ("andere Tenside") und 10 Gew.% bis 70 Gew.% einer gut wasserlöslichen festen organischen Verbindung, die nicht waschaktiv ist und keine Gele bildet, mit einer maximalen Molmasse von 500 g/mol.This object is achieved by an agent for cleaning laundry which comprises surfactants and possibly also fragrances, which contains less than 5% by weight of alkane carboxylic acid salts, between 20% by weight and 60% by weight of solvent, of which at least 10% by weight of water and 10% by weight to 50% by weight of surfactants which are different from the alkane carboxylic acid salts ("other surfactants") and 10% by weight to 70% by weight of a readily water-soluble solid organic compound which is not washable and does not form gels, with a maximum molar mass of 500 g / mol.
Das erfindungsgemäße Mittel ist ein festes Gel, es ist schnittfest und transparent. Damit kann es nicht auslaufen und ist einfach verpackbar. Infolge der Transparenz ist es auch optisch ansprechend. Zudem löst es sich innerhalb eines Waschzyklus vollständig auf.The agent according to the invention is a solid gel, it is cut-resistant and transparent. It cannot leak and is easy to pack. Due to the transparency, it is also visually appealing. It also dissolves completely within one wash cycle.
In dem erfindungsgemäßen Konzentrationsbereich von Alkancarbonsäuresalzen, Lösemitteln, anderen Tensiden und den gut wasserlöslichen festen organischen Verbindungen werden hinreichend harte, transparente Gele erhalten, die gut reinigen, schäumen und sich in einem Spülzyklus vollständig auflösen.In the concentration range of alkane carboxylic acid salts, solvents, other surfactants and the readily water-soluble solid organic compounds according to the invention, sufficiently hard, transparent gels are obtained which clean well, foam and dissolve completely in a rinse cycle.
Der Anteil an Alkancarbonsäuresalzen sollte unterhalb von 5 Gew.% und vorzugsweise unterhalb von 4 Gew.% liegen und wenigstens 0,5 Gew.% und bevorzugt wenigstens 1 Gew.% und besonders bevorzugt etwa 3 Gew.% betragen. Bei einem höheren Anteil an Alkancarbonsäuresalzen ist das Reinigungsmittel zwar hart, transparent und schnittfest, wie es von den transparenten Kosmetikseifen bekannt ist, allerdings spült sich ein solches Mittel nicht in einem Spülzyklus ab.The proportion of alkane carboxylic acid salts should be below 5% by weight and preferably below 4% by weight and should be at least 0.5% by weight and preferably at least 1% by weight and particularly preferably about 3% by weight. With a higher proportion of alkane carboxylic acid salts, the cleaning agent is hard, transparent and cut-resistant, as is known from the transparent cosmetic soaps, but such an agent does not wash off in a rinsing cycle.
Als Salze der Alkancarbonsäuren werden im Rahmen der vorliegenden Erfindung die Salze der aliphatischen oder ungesättigten Alkancarbonsäuren eingesetzt. Vorzugsweise weisen die Alkancarbonsäuresalze eine Kohlenstoffkette mit zwischen 10 und 24 Kohlenstoffatomen auf und sind Monocarbonsäuresalze, insbesondere Alkaliseifen. Besonders bevorzugte Alkancarbonsäuresalze sind Salze von Stearin-, Laurin-, Myristin-, Palmitin-, Ölsäure und/oder C-Schnitte derselben aus natürlichen oder synthetischen Quellen. Wegen der biologischen Abbaubarkeit sind insbesondere die geradzahligen, unverzweigten Alkancarbonsäuresalze mit natürlichen C-Quellen-Schnitten besonders geeignet.In the context of the present invention, the salts of aliphatic or unsaturated alkane carboxylic acids are used as salts of the alkane carboxylic acids. The alkane carboxylic acid salts preferably have a carbon chain with between 10 and 24 carbon atoms and are monocarboxylic acid salts, in particular alkali soaps. Particularly preferred alkane carboxylic acid salts are salts of stearic, lauric, myristic, palmitic, oleic acid and / or C-cuts thereof from natural or synthetic sources. Because of their biodegradability, the even-numbered, unbranched alkane carboxylic acid salts with natural C source cuts are particularly suitable.
Das erfindungsgemäße Mittel umfasst wenigstens ein Alkancarbonsäure-salz, es können jedoch auch mehrere Alkancarbonsäuresalze miteinander kombiniert werden.The agent according to the invention comprises at least one alkane carboxylic acid salt, but several can also Alkane carboxylic acid salts can be combined.
Die Alkancarbonsäuresalze sind vorzugsweise Alkalisalze und insbesondere Natrium- und/oder Kaliumsalze.The alkane carboxylic acid salts are preferably alkali salts and in particular sodium and / or potassium salts.
Die Alkancarbonsäuresalze fungieren in der Formulierung hauptsächlich als Gelbildner, die Reinigungsleistung der Alkancarbonsäuresalze ist gering.In the formulation, the alkane carboxylic acid salts mainly function as gel formers, and the cleaning performance of the alkane carboxylic acid salts is poor.
Aus diesem Grund weist die Formulierung noch andere Tenside auf, die reinigen und schäumen.For this reason, the formulation has other surfactants that clean and foam.
Der Anteil an Tensiden in dem Mittel, die keine Alkancarbonsäuren sind und im Rahmen der vorliegenden Erfindung als "andere Tenside" bezeichnet werden, hängt von der gewünschten Reinigungs- und Schaumleistung ab.The proportion of surfactants in the composition which are not alkane carboxylic acids and which are referred to in the context of the present invention as "other surfactants" depends on the desired cleaning and foaming performance.
Der Anteil an anderen Tensiden liegt zwischen 10 Gew.% und 50 Gew.%, vorzugsweise zwischen 15 Gew.% und 35 Gew.% und besonders bevorzugt 20 Gew.% ± 5 Gew.%.The proportion of other surfactants is between 10% by weight and 50% by weight, preferably between 15% by weight and 35% by weight and particularly preferably 20% by weight ± 5% by weight.
Die anderen Tenside können aus der Gruppe der anionischen, nichtionischen, kationischen oder amphoteren Tenside ausgewählt werden oder Mischungen derselben sein, insbesondere aus anionischen und nichtionischen Tensiden.The other surfactants can be selected from the group of anionic, nonionic, cationic or amphoteric surfactants or mixtures thereof, in particular from anionic and nonionic surfactants.
Um eine gute Reinigungswirkung und das gewünschte Schäumen zu erzielen, sollte das Mittel anionische Tenside enthalten, vorzugsweise zwischen 5 Gew.% und 40 Gew.%, vorzugsweise zwischen 10 Gew.% und 20 Gew.%.In order to achieve a good cleaning effect and the desired foaming, the agent should contain anionic surfactants, preferably between 5% by weight and 40% by weight, preferably between 10% by weight and 20% by weight.
Unter den anionischen Tensiden sind insbesondere die Alkylsulfate, Alkylethersulfate, die Sulfonate wie beispielsweise die Alkylsulfonate, die Olefinsulfonate, die Alkoxyalkansulfonate, die Alkylarylsulfonate wie die Alkylbenzolsulfonate oder die Toluolsulfonate, die Sulfatester, die Alkylcarbonate, Alkyethercarboxylate, die Fettsäuretauride, die Alkylisothionate und deren Mischungen bevorzugt.Among the anionic surfactants, the alkyl sulfates, alkyl ether sulfates, the sulfonates such as, for example, the alkyl sulfonates, the olefin sulfonates, the alkoxyalkanesulfonates, the alkylarylsulfonates such as the alkylbenzenesulfonates or the toluenesulfonates, the sulfate esters, the alkyl carbonates, alkyl ether carboxylates, and the fatty acid isothurides, the fatty acid isothurides, the fatty acid isothurides, are preferred .
Die nichtionischen Tenside dienen im Wesentlichen zum Homogenisieren und zum Klarstellen des Gels, ihre Reinigungswirkung ist insbesondere bei hohen Konzentrationen von Erdalkali-Ionen im verwendeten Wasser, bei niedriger Tensiddosierung und beim Waschen mit niedrigen Temperaturen vorteilhaft.The nonionic surfactants are mainly used for homogenizing and clarifying the gel, their cleaning effect is particularly high at high concentrations of alkaline earth metal ions in the water used, at low surfactant dosage and when washing with low Temperatures advantageous.
Der Anteil an nichtionischen Tensiden liegt vorzugsweise zwischen 0 Gew.% und 40 Gew.%, vorzugsweise unterhalb von 30 Gew.%, insbesondere zwischen 5 Gew.% und 20 Gew.%.The proportion of nonionic surfactants is preferably between 0% by weight and 40% by weight, preferably below 30% by weight, in particular between 5% by weight and 20% by weight.
Als nichtionische Tenside können beispielsweise Alkylethoxylate wie C8 - C30-Alkoholethoxylat mit bis zu 60 EO, ethoxylierte Alkyphenole, ethoxylierte oder propoxylierte Fettalkohole, Zuckertenside wie Alkylpolyglycoside, Polyethylenglykolether, ethoxylierte Fettsäureester, Kondensationsprodukte von Ethylenoxid mit langkettigen Aminen oder Amiden oder vergleichbare Verbindungen, Aminoxide, Trisiloxanalkoxylate oder deren Mischungen eingesetzt werden.Examples of nonionic surfactants that can be used are alkyl ethoxylates such as C8-C30 alcohol ethoxylate with up to 60 EO, ethoxylated alkyphenols, ethoxylated or propoxylated fatty alcohols, sugar surfactants such as alkyl polyglycosides, polyethylene glycol ethers, ethoxylated fatty acid esters, condensation products of ethylene oxide with long-chain amines or amides, or amine alkoxides, amine oxides, amine alkoxides, or comparable compounds, amine alkoxides, amine alkoxides, or comparable compounds, amine alkoxides, amine alkoxides, amine alkoxides, or comparable compounds, amine alkoxides, amine alkoxides, or comparable compounds, amine alkoxides, amine alkoxides, or comparable compounds, amine alkoxides, amine alkoxides, or comparable compounds, amine alkoxides, amine alkoxides, or comparable compounds, amine alkoxides, amine alkoxides, or comparable compounds, amine alkoxides, amine alkoxides, or comparable compounds, amine alkoxides, amine alkoxides or comparable compounds, amine alkoxides, or any other compounds, amine alkoxides or comparable compounds, amine alkoxides, or mixtures thereof are used.
Als amphotere Tenside können beispielsweise Betaine eingesetzt werden und als kationische Tenside quartäre Alkylammoniumverbindungen. Im Falle von kationischen Tensiden muss bei der Auswahl darauf geachtet werden, dass keine Wolkenbildung durch die Bildung von Neutralkomplexen erfolgt.Betaines, for example, can be used as amphoteric surfactants and quaternary alkylammonium compounds as cationic surfactants. In the case of cationic surfactants, care must be taken in the selection that no cloud formation occurs due to the formation of neutral complexes.
Um die gewünschte vollständige Auflösung des Reinigungsmittels innerhalb eines Waschgangs zu erreichen, sollte das Reinigungsmittel keine oder höchstens nur sehr geringe Mengen polymere oder höhermolekulare Verbindungen aufweisen, da diese die Auflösegeschwindigkeit erniedrigen. Insbesondere sollte das erfindungsgemäße Mittel maximal 3 Gew.%, vorzugsweise maximal 1 Gew.% und besonders bevorzugt keine Polymere mit einer Molmasse von mehr als 5000 g/mol bzw. mehr als 4000 g/mol aufweisen. Weiterhin sollten vorzugsweise maximal 3 Gew.%, maximal 1 Gew.% oder keine Polymere mit einer Molmasse von nicht mehr als 2000 g/mol und vorzugsweise nicht mehr als 1500 g/mol in dem Mittel enthalten sein.In order to achieve the desired complete dissolution of the cleaning agent within a washing cycle, the cleaning agent should have no or at most only very small amounts of polymeric or higher molecular weight compounds, since these reduce the dissolution rate. In particular, the agent according to the invention should have a maximum of 3% by weight, preferably a maximum of 1% by weight and particularly preferably no polymers with a molecular weight of more than 5000 g / mol or more than 4000 g / mol. Furthermore, a maximum of 3% by weight, a maximum of 1% by weight or no polymers with a molecular weight of not more than 2000 g / mol and preferably not more than 1500 g / mol should be present in the composition.
Bei den Polymeren mit der maximalen Molmasse von 5000 g/mol, 4000 g/mol, 2000 g/mol oder 1500 g/mol, die nur in geringsten Konzentrationen oder vorzugsweise überhaupt nicht in dem Mittel enthalten sein sollten, kann es sich beispielsweise um Oligo- oder Polyalkylenoxid umfassende Blockcopolymere oder Polymere oder Biopolymere handeln.The polymers with the maximum molecular weight of 5000 g / mol, 4000 g / mol, 2000 g / mol or 1500 g / mol, which should only be present in the agent in very low concentrations or preferably not at all, can be oligo, for example block copolymers or polymers or biopolymers comprising polyalkylene oxide.
Unter einer "vollständigen Auflösung des Reinigungsmittels innerhalb eines Waschvorgangs wird im Rahmen der vorliegenden Erfindung verstanden, dass bei einer Wäsche in einer Waschmaschine bei 30 °C und 90 Minuten Waschdauer keine Partikel mit einem Volumen von mehr als 3 mm3 vorhanden sind.Taking a "complete dissolution of the detergent within A washing process is understood in the context of the present invention that when washing in a washing machine at 30 ° C. and a washing time of 90 minutes, there are no particles with a volume of more than 3 mm 3 .
Der Lösemittelanteil in dem Mittel sollte maximal 60 Gew.% betragen. Im Rahmen der vorliegenden Erfindung werden Parfümöle zu den Lösemitteln gerechnet. Der Anteil an Lösemitteln wirkt sich zudem auf die Härte des Mittels aus. Aus diesem Grund sollte der Anteil an Lösemitteln in dem Mittel vorzugsweise zwischen 25 Gew.% und 50 Gew.% und besonders bevorzugt zwischen 40 Gew. % und ± 5 Gew.% betragen.The solvent content in the agent should not exceed 60% by weight. In the context of the present invention, perfume oils are included in the solvents. The proportion of solvents also affects the hardness of the agent. For this reason, the proportion of solvents in the composition should preferably be between 25% by weight and 50% by weight and particularly preferably between 40% by weight and ± 5% by weight.
Die Lösemittel sind auch erforderlich, um mit dem Gelbildner Gele zu bilden. Der Anteil an Lösemittel muss mit der Menge an Gelbildner korrespondieren. Im Allgemeinen sollte der gewichtsprozentuale Anteil an Lösemittel bezogen auf die Alkancarbonsäuresalze, insbesondere Natriumstearat, zwischen 3 : 1 bis 20 : 1 betragen, vorzugsweise zwischen 4:1 und 12:1.The solvents are also required to form gels with the gelling agent. The proportion of solvent must correspond to the amount of gel former. In general, the percentage by weight of solvent based on the alkane carboxylic acid salts, in particular sodium stearate, should be between 3: 1 to 20: 1, preferably between 4: 1 and 12: 1.
Als Lösemittel können organische und/oder anorganische Lösemittel eingesetzt werden. Bevorzugte Lösemittel bzw. Hauptbestandteile eines Lösemittelgemisches sind Wasser und Alkohole, insbesondere mehrwertige Alkohole. Als Alkohole können beispielsweise Isopropanol, 1,2-Propylenglykol, Dipropylenglykol, Butylenglykol, Ethylenglykol, 1,7-Heptandiol, Glycerin, Glycerinderivate, Monoethylenglykole sowie die Mono-C1-4-Alkylether der vorangegangenen Verbindungen ausgewählt werden.Organic and / or inorganic solvents can be used as solvents. Preferred solvents or main components of a solvent mixture are water and alcohols, especially polyhydric alcohols. As alcohols, for example, isopropanol, 1,2-propylene glycol, dipropylene glycol, butylene glycol, ethylene glycol, 1,7-heptanediol, glycerol, glycerol derivatives, monoethylene glycols and the mono-C 1-4 -alkyl ethers of the preceding compounds can be selected.
Mit Wasser als Lösemittel werden mit dem Gelbildner schnittfeste transparente Gele erhalten. Das Mittel weist wenigstens 10 Gew.%, vorzugsweise wenigstens 15 Gew.%, bevorzugt wenigstens 20 Gew.% und besonders bevorzugt mehr als 25 Gew.% Wasser auf. Der maximale Wassergehalt sollte bei 60, vorzugsweise bei 45 und besonders bevorzugt bei 30 Gew.% liegen.With water as a solvent, cut-resistant transparent gels are obtained with the gel former. The agent has at least 10% by weight, preferably at least 15% by weight, preferably at least 20% by weight and particularly preferably more than 25% by weight of water. The maximum water content should be 60, preferably 45 and particularly preferably 30% by weight.
Vorzugsweise werden 0 Gew.% bis 20 Gew.%, besonders bevorzugt zwischen 8 Gew.% und 15 Gew.% mehrwertige Alkohole eingesetzt. Die mehrwertigen Alkohole tragen dazu bei, dass die Massen transparenter werden und sind somit ein Klarstellmittel.Preferably, 0% by weight to 20% by weight, particularly preferably between 8% by weight and 15% by weight, of polyhydric alcohols are used. The polyhydric alcohols help make the masses more transparent are and are therefore a clarifying agent.
Alternativ zu den mehrwertigen Alkoholen kann auch der Anteil an Wasser erhöht werden und zusätzlich ein anderes die Transparenz erhöhendes Mittel wie nichtionische Tenside zugefügt werden.As an alternative to the polyhydric alcohols, the proportion of water can also be increased and another transparency-increasing agent such as nonionic surfactants can also be added.
Falls gewünscht, kann das erfindungsgemäße Mittel zur Beduftung weiterhin Parfümöle enthalten, beispielsweise in einer Menge von 0,5 Gew.% bis 5 Gew.%.If desired, the fragrancing agent according to the invention can further contain perfume oils, for example in an amount of 0.5% by weight to 5% by weight.
Generell können als Parfümöle einzelne synthetische Produkte wie Ether, Ester, Aldehyde oder Ketone eingesetzt werden. Hierzu zählen beispielsweise Benzylacetat (Ester), Benzylethylether (Ether), Citral, Citronellal (Aldehyd), Citronellol oder Eugenol (Alkohole). Bevorzugt werden Mischungen eingesetzt, die ein typisches sensorisches Profil liefern.In general, individual synthetic products such as ethers, esters, aldehydes or ketones can be used as perfume oils. These include, for example, benzyl acetate (ester), benzyl ethyl ether (ether), citral, citronellal (aldehyde), citronellol or eugenol (alcohols). Mixtures which provide a typical sensory profile are preferably used.
Ein weiterer wesentlicher Bestandteil der erfindungsgemäßen Formulierung ist eine gut wasserlösliche, feste organische Verbindung mit einer Molmasse von maximal 500 g/mol, die keine Gele bildet und nicht waschaktiv ist. Solche Verbindungen tragen zur gewünschten Härte des Mittels bei, ohne die Transparenz zu beeinträchtigen, sie führen infolge ihrer guten Wasserlöslichkeit zu der gewünschten schnellen Auflösung des Reinigungsmittels in einem Waschvorgang und verhindern infolge ihrer geringen Größe auch die Bildung von Kalkseifen und verbessern die Transparenz des Reinigungsmittels.Another essential constituent of the formulation according to the invention is a readily water-soluble, solid organic compound with a maximum molecular weight of 500 g / mol, which does not form gels and is not washable. Such compounds contribute to the desired hardness of the agent without impairing the transparency, they lead to the desired rapid dissolution of the cleaning agent in a washing process due to their good water solubility and, due to their small size, also prevent the formation of lime soaps and improve the transparency of the cleaning agent.
Unter "gut wasserlöslich" wird verstanden, dass die Löslichkeit dieser Verbindungen in Wasser bei einer Temperatur von 25 °C wenigstens 30 g/l, bevorzugt wenigstens 100 g/l und besonders bevorzugt wenigstens 500 g/l beträgt. Unter "fest" wird verstanden, dass die Verbindung bei 25 °C fest ist.“Well water-soluble” is understood to mean that the solubility of these compounds in water at a temperature of 25 ° C. is at least 30 g / l, preferably at least 100 g / l and particularly preferably at least 500 g / l. "Solid" means that the connection is solid at 25 ° C.
Der Anteil an diesen gut wasserlöslichen Verbindungen mit einer Molmasse von maximal 500 g/mol in dem Mittel liegt zwischen 10 Gew.% und 70 Gew.%, vorzugsweise zwischen 20 Gew.% und 50 Gew.% und besonders bevorzugt zwischen 30 Gew.% und 40 Gew.% und hängt u.a. von der gewünschten Auflösegeschwindigkeit und damit von der Löslichkeit und der Konzentration der weiteren Komponenten ab.The proportion of these readily water-soluble compounds with a molecular weight of at most 500 g / mol in the average is between 10% by weight and 70% by weight, preferably between 20% by weight and 50% by weight and particularly preferably between 30% by weight and 40% by weight and depends, inter alia, on the desired dissolution rate and thus on the solubility and the concentration of the further components.
Um eine vollständige Auflösung eines solchen stückförmigen Reinigungsmittel mit einer Masse von ca. 25 g und abgefüllt in einem kissenförmigen, wasserlöslichen Beutel in einem Waschgang zu erreichen, weist das Mittel wenigstens einen Anteil von 15 Gew.%, vorzugsweise von 25 Gew.% und besonders bevorzugt von 30 Gew.% solcher gut wasserlöslicher fester organischer Verbindungen auf.In order to achieve complete dissolution of such a piece-like cleaning agent with a mass of approx. 25 g and filled in a pillow-shaped, water-soluble bag in one wash cycle, the agent has at least a proportion of 15% by weight, preferably 25% by weight and particularly preferably of 30% by weight of such readily water-soluble solid organic compounds.
Im Rahmen der vorliegenden Erfindung werden unter Zucker Mono- oder Oligosaccharide, wie beispielsweise die Hexosen, Pentosen oder deren Di- oder Trisaccharide verstanden. Besonders bevorzugt sind unter den Monosacchariden die Glucose, Fructose, Arabiose, Ribose, Xylose, Mannose und Galactose und unter den Disacchariden die Saccharose, Maltose, Lactose, Raffinose und Cellobiose aus natürlichen oder synthetischen Quellen, unabhängig von ihrer Fischer-Konfiguration sowie alle Epimere, die auf diesen Zuckern basieren.In the context of the present invention, sugar is understood to mean mono- or oligosaccharides, such as, for example, hexoses, pentoses or their di- or trisaccharides. Particularly preferred among the monosaccharides are glucose, fructose, arabinose, ribose, xylose, mannose and galactose and among the disaccharides sucrose, maltose, lactose, raffinose and cellobiose from natural or synthetic sources, regardless of their Fischer configuration, as well as all epimers, based on these sugars.
Als reduzierte Formen der Zucker oder der Zuckerderivate können sämtliche unter Erhalt der C-Kette reduzierte Zucker eingesetzt werden wie die Desoxyzucker und die Zuckeralkohole.All sugars reduced while maintaining the C chain, such as the deoxy sugars and the sugar alcohols, can be used as reduced forms of the sugar or the sugar derivatives.
Besonders bevorzugt werden als Zuckeralkohole Hexitole wie das Sorbitol (Glucitol), Allitol, Glucitol, Mannitol, Altritol, Iditol, Pentitole wie das Ribitol, Arabinitol und Xylitol und Tetritole wie Erythritol und Theitol, jeweils mit ihren verschiedenen Enantiomeren, eingesetzt.

Wahlweise kann das Mittel auch noch andere Bestandteile wie Bleichmittel, Oxidationsmittel, Korrosionsschutzmittel, Nano-Partikel, keimtötende Mittel oder dekorative Farbgranulate umfassen. Auch der Zusatz von Farbstoffen ist möglich, wobei bei der Zugabe von Farbstoffen allerdings bedacht werden muss, dass der Transparenzeindruck infolge von zunehmender Lichtabsorption durch die Farbstoffe abnimmt.The agent can optionally also comprise other constituents such as bleaching agents, oxidizing agents, anti-corrosion agents, nano-particles, germicidal agents or decorative color granules. The addition of dyes is also possible, although it must be taken into account when adding dyes that the transparency impression decreases as a result of increasing light absorption by the dyes.
Das Mittel sollte neben den Alkancarbonsäuresalzen sowie den ggf. vorhandenen weiteren anionischen Tensiden höchstens 5 Gew.% weitere Salze, vorzugsweise maximal 3 Gew.% weitere Salze und besonders bevorzugt keine weiteren Salze aufweisen.In addition to the alkane carboxylic acid salts and any further anionic surfactants which may be present, the composition should have at most 5% by weight of further salts, preferably at most 3% by weight of further salts and particularly preferably no further salts.
Das erfindungsgemäße Mittel kann auch Bestandteil einer mehrphasigen Waschmitteltablette sein.The agent according to the invention can also be part of a multi-phase detergent tablet.
Die Komponenten des erfindungsgemäßen Mittels werden vorzugsweise zusammen geschmolzen und dann in eine beliebige, geschlossene Form mit wenigstens einer Öffnung gegossen, um dort zu erstarren. Die Befüllung kann mit den bekannten diskontinuierlich und kontinuierlich arbeitenden Verfahren erfolgen.The components of the agent according to the invention are preferably melted together and then poured into any closed mold with at least one opening in order to solidify there. Filling can be carried out using the known batch and continuous processes.
Das erfindungsgemäße Mittel weist einen Schmelzpunkt von wenigstens 30 °C, vorzugsweise wenigstens 35 °C und besonders bevorzugt wenigstens 40 °C auf. Besonders bevorzugt sind Schmelzpunkte über 45 °C.The agent according to the invention has a melting point of at least 30 ° C., preferably at least 35 ° C. and particularly preferably at least 40 ° C. Melting points above 45 ° C. are particularly preferred.
Die erfindungsgemäßen Mittel zeichnen sich auch durch eine hinreichende Härte bei Raumtemperatur aus, sie sind dabei schnittfest und formstabil.The agents according to the invention are also characterized by a sufficient hardness at room temperature, they are cut-resistant and dimensionally stable.
Die erfindungsgemäßen Reinigungsmittel weisen als erforderliche Härte einen Wert von mindestens 20 mN/mm auf.The cleaning agents according to the invention have a required hardness of at least 20 mN / mm.
Die erfindungsgemäßen Mittel sind transparent. Ein Mittel ist im Sinne der vorliegenden Erfindung transparent, wenn die Transmission des Mittels mit einer Schichtdicke von 10 mm gemessen gegen eine leere Küvette der Schichtdicke von 10 mm wenigstens 60 %, vorzugsweise wenigstens 70 %, beträgt. Die Transmission wird dabei im Sichtbaren, d.h. zwischen 400 nm und 800 nm bestimmt, und die Transmission sollte wenigstens bei einer Wellenlänge im Sichtbaren die obige Mindesttransmission aufweisen.The agents according to the invention are transparent. For the purposes of the present invention, an agent is transparent if the transmission of the agent with a layer thickness of 10 mm measured against an empty cuvette with a layer thickness of 10 mm is at least 60%, preferably at least 70%. The transmission is in the visible, i.e. determined between 400 nm and 800 nm, and the transmission should have the above minimum transmission at least at a wavelength in the visible.
Unter "schnittfest" wird im Rahmen der vorliegenden Erfindung ein Mittel verstanden, das bei einer Temperatur von 25 °C geschnitten werden kann, ohne dass es verläuft.In the context of the present invention, “cut-resistant” means an agent that can be cut at a temperature of 25 ° C. without running.
Unter "formstabil" wird verstanden, dass das Mittel, nachdem es in eine dreidimensionale Form gegossen wurde und es für mindestens 24 Stunden ausgehärtet ist, diese Form bei 25 °C auch ohne mechanische Unterstützung durch bspw. Gussformen oder Verpackungen für mindestens 24 Stunden behält. Das Mittel verändert seine Form also nicht unter ausschließlichem Einfluss der Schwerkraft.“Dimensionally stable” is understood to mean that the agent, after it has been cast into a three-dimensional mold and has cured for at least 24 hours, retains this shape at 25 ° C. for at least 24 hours even without mechanical support from, for example, molds or packaging. The medium therefore does not change its shape under the exclusive influence of gravity.
Ein weiterer wesentlicher Vorteil der vorliegenden Erfindung ist, dass die Formulierung in eine PVA-Folie eingefüllt und gelagert werden kann.Another significant advantage of the present invention is that the Formulation can be filled into a PVA film and stored.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher beschrieben.
Bei der Herstellung wurden die Tenside aufgeschmolzen, der Zucker zugegeben und dann das Wasser hinzugefügt und die Mischung dann erkalten lassen.During the manufacture, the surfactants were melted, the sugar added and then the water added and the mixture was then allowed to cool.
Die Formulierungen V1, V2 und V3 sind transparent, hart, formstabil und schnittfest.
Die Härtemessungen wurden mit dem Druckkraftmesser PCE-FG 2050 von PCE Instruments (PCE Deutschland GmbH) und der enthaltenen Edelstahl-Messspitze "Stempel" durchgeführt. Zur definierten Positionierung war das Druckkraftmessgerät am Teststand PCE-FTS50 von PCE Instruments (PCE Deutschland GmbH) montiert, um eine exakte vertikale Verschiebung mit einer Auflösung von 0,01 mm zu gewährleisten. Zur Bestimmung der Härte wurde die Zubereitung in eine Petrischale gegossen und konnte für mindestens 24 Stunden bei 23 °C aushärten. Zur Härtemessung wurde die Messspitze knapp oberhalb der Probenoberfläche positioniert und die Messspitze in Schritten von 0,1 mm in Richtung Probenoberfläche nach unten bewegt (Absenkgeschwindigkeit 0,02 mm/s) und der Kraftwert an der entsprechenden Stelle gespeichert. Als Nullpunkt der Eindringtiefe x wurde die Position definiert, bei der an der darauf folgenden Position erstmals eine Kraft gemessen wurde. Die Messspitze wurde jeweils bis auf eine Eindringtiefe von 1,0 mm in die Probe geführt. Die Temperatur während der Messung betrug 20 °C. Als Messgröße der Härte wurde der Anstieg des gemessenen Drucks in Abhängigkeit der Eindringtiefe verwendet.The hardness measurements were carried out with the pressure force meter PCE-FG 2050 from PCE Instruments (PCE Deutschland GmbH) and the included stainless steel measuring tip "Stempel". For the defined positioning, the pressure force measuring device was mounted on the test stand PCE-FTS50 from PCE Instruments (PCE Deutschland GmbH) in order to guarantee an exact vertical displacement with a resolution of 0.01 mm. To determine the hardness, the preparation was poured into a petri dish and was allowed to harden at 23 ° C. for at least 24 hours. For the hardness measurement, the measuring tip was positioned just above the sample surface and the measuring tip was moved downwards in steps of 0.1 mm towards the sample surface (lowering speed 0.02 mm / s) and the force value was stored at the corresponding point. The position at which a force was measured for the first time at the following position was defined as the zero point of the penetration depth x. The measuring tip was inserted into the sample to a depth of 1.0 mm. The temperature during the measurement was 20 ° C. The increase in the measured pressure as a function of the depth of penetration was used as the measure of the hardness.
