Abstract
Description
The application relates to a detergent portion unit. In particular, the application relates to a laundry detergent portion unit having a plurality of receiving chambers, wherein at least one receiving chamber has a small internal volume and is predominantly filled with a single active substance. Furthermore, the application relates to a method for producing the detergent portion unit and to a method for washing textiles using the detergent portion unit.The confection and supply forms of washing and cleaning agents are subject to continuously changing requirements. A focus has been on the convenient metering of washing and cleaning agents by the consumer for some time and the simplification of the working steps required for carrying out a washing or cleaning process. A technical solution provides pre-sized washing or cleaning agents, for example foil bags with one or more receiving chambers for solid or liquid washing or cleaning agents.A trend relevant for the production of these film bags is the miniaturization of these film bags, i.e. the reduction of their fillable internal volume. In addition to a higher consumer acceptance, the background of this development is, owing to simplified handling, in particular sustainability aspects, for example with respect to transport volumes and the amount of packaging materials used.Formulating efficient detergent formulations for film bags having a reduced internal volume presents a challenge to the developers. Corresponding film bags can contain only small amounts of non-wash-active ingredients, which is why the use of stabilizing but non-wash-active solvent systems, for example, must be limited in liquid detergents. In the resulting highly concentrated gels, in turn, the storage stability is frequently reduced on account of incompatibilities of different active substances with one another. Furthermore, solid active substances often cannot be suspended in a sufficiently stable manner.One way of proceeding from the above-described problems is to make up the detergents in multi-chamber portion units, in which the chambers permit both the separation of incompatible active substances and the separate making up of liquid and solid active substances.As the film bags are progressively miniaturized, however, these multi-chamber portion units have increasingly small and smallest chambers. The reduction of the chamber volumes makes it difficult to fill the chambers precisely and uniformly. Unlike liquids, the composition or density of the powders filled into the compartments can vary due to separation processes prior to formulation. The effects of these variations on the performance of the detergent portion units increase as the chamber volume decreases.Against this background, the object of the application was to provide powerful compact detergent portion units which can be produced efficiently in constant quality, have good storage capacity and a good primary and secondary washing action.A first subject matter of the application is a laundry detergent portion unit which comprises a plurality of receiving chambers which are each surrounded by at least one water-soluble film, wherein the receiving chambers are formed by water-soluble films which are connected to one another in a sealing plane and are separated from one another by sealing sections lying in the sealing plane, and wherein the receiving chambers are each filled with a laundry detergent preparation, whereina plurality of receiving chambers with the number n≥3 is provided;the total internal volume of all receiving chambers is 10 to 25 ml;the plurality of receiving chambers comprises at least one receiving chamber K min having an internal volume of less than 3 ml;the at least one receiving chamber K min is filled with a powder P min which consists to an extent of at least 60% by weight of an active substance A min.The laundry detergent portion unit comprises at least three receiving chambers. Of these receiving chambers, at least one receiving chamber K min has an internal volume of less than 3 ml. The inner volume of a receiving chamber is referred to here as the volume of the receiving chamber enclosed by the water-soluble film. Preferred detergent portion units have three receiving chambers or four receiving chambers or five receiving chambers.The structure according to the invention of the detergent portion units has technical advantages as the number of receiving chambers increases. Detergent portion units having a plurality of receiving chambers with the number n≥4, preferably with the number n≥5, are therefore preferred.The total internal volume of all receiving chambers of the detergent portion unit is 10 to 25 ml, preferably 10 to 20 ml and in particular 10 to 18 ml.The internal volume of the receiving chamber K min is less than 3 ml. Preferred detergent portion units have at least one receiving chamber K min with an internal volume of between 0.1 and 3 ml, preferably between 0.2 and 2.5 ml and in particular between 0.5 and 2 ml.In a particularly preferred embodiment, the laundry detergent portion unit comprises a receiving chamber K min and the further receiving chambers of the laundry detergent portion unit have an internal volume above the internal volume of the receiving chamber K min. Particularly preferably, the detergent portion unit comprises a single receiving chamber K min and the further receiving chambers of the detergent portion unit have an internal volume above 3 ml.In preferred embodiments, the laundry detergent portion unit comprises a receiving chamber K min and the further receiving chambers of the laundry detergent portion unit have an internal volume above 3 ml, wherein the internal volume of the further receiving chambers is at least 150%, preferably at least 300% and in particular at least 400%, of the internal volume of the receiving chamber K min.The structure of some particularly preferred detergent portion units can be found in the following tables (details of the internal volume of the receiving chambers in ml).

Detergent portion units are therefore preferred in which the receiving chambers are arranged in at least one sectional plane about a common n-fold axis of rotation perpendicular to the sectional plane and wherein at least one receiving chamber K is arranged in min as a central chamber in the central region of the detergent portion unit and the further receiving chamber(s) are arranged around the central chamber.The receiving chambers are surrounded by at least one water-soluble film. The receiving chambers are preferably formed by forming a water-soluble film into a deep-drawing die. After they have been filled, the receiving chambers are sealed with a water-soluble film in a subsequent step. In an embodiment which is preferred on account of its efficiency and ease of execution, the receiving chambers of the detergent portion unit are formed by two water-soluble films which are connected to one another in a sealing plane.The water-soluble film may comprise one or more structurally different water-soluble polymer(s). Suitable water-soluble polymer(s) are, in particular, polymers from the group of (optionally acetalized) polyvinyl alcohols (PVAL) and copolymers thereof.Water-soluble films for producing the water-soluble coating are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in the range from 10,000 to 1,000,000 gmol -1, preferably from 20,000 to 500,000 gmol -1, particularly preferably from 30,000 to 100,000 gmol -1 and in particular from 40,000 to 80,000 gmol -1.The preparation of the polyvinyl alcohol and polyvinyl alcohol copolymers typically involves the hydrolysis of intermediate polyvinyl acetate. Preferred polyvinyl alcohols and polyvinyl alcohol copolymers have a degree of hydrolysis of 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %.Preferred polyvinyl alcohol copolymers comprise, in addition to vinyl alcohol, an ethylenically unsaturated carboxylic acid, its salt or its esters. Particularly preferably, such polyvinyl alcohol copolymers contain, in addition to vinyl alcohol, sulfonic acids such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acrylic acid, methacrylic acid, acrylic esters, methacrylic esters or mixtures thereof; among the esters, C 1-4- alkyl esters or hydroxyalkyl esters are preferred. Other suitable monomers are ethylenically unsaturated dicarboxylic acids, for example itaconic acid, maleic acid, fumaric acid and mixtures thereof.Suitable water-soluble films for use in the envelopes of the water-soluble packages according to the invention are films which are marketed by the company MonoSol LLC, for example under the name M8630, M8720, M8310, C8400 or M8900. Other suitable films include Solublon® PT, Solublon® GA, Solublon® KC, or Solublon® KL films from Aicello Chemical Europe GmbH, or VF-HP films from Kuraray.The water-soluble films can contain additional active substances or fillers as further ingredients, but also plasticizers and / or solvents, in particular water.The group of further active ingredients includes, for example, materials which protect the ingredients enclosed by the film material from decomposition or deactivation by light irradiation. Antioxidants, UV absorbers and fluorescent dyes have proven particularly suitable here.Examples of plasticizers which can be used are glycerol, ethylene glycol, diethylene glycol, propanediol, 2-methyl-1,3-propanediol, sorbitol or mixtures thereof.To reduce their coefficients of friction, the surface of the water-soluble film may optionally be powdered with fine powder. Sodium aluminosilicate, silica, talc and amylose are examples of suitable powders.In a particularly preferred embodiment, the receiving chambers of the detergent portion unit are formed by two water-soluble films connected to one another in a sealing plane, wherein the two water-soluble films have a different composition.The receiving chamber K min preferably has a filling degree above 70% by volume, particularly preferably above 78% by volume and in particular above 85% by volume. With particular preference all receiving chambers have a filling degree above 70% by volume, preferably above 80% by volume and in particular above 90% by volume.The receiving chamber K min is filled with a powder P min which consists of an active substance to the extent of 60% by weight, preferably to the extent of at least 70% by weight, preferably to the extent of at least 80% by weight, particularly preferably to the extent of at least 85% by weight, very particularly preferably to the extent of at least 90% by weight and in particular to the extent of at least 98% by weight.By filling the receiving chamber K min with a powder which substantially consists of an active substance, separation phenomena are avoided, as occur during the filling of powders which consist of a large number of different active substances. In such powders, the different active substances tend to separate on account of their different granulometry and density during their conveyance and filling. The separation in turn causes an uneven distribution of the active substances over the detergent portion units produced in one process operation and thus brings about fluctuations in the product performance of different detergent portion units.Such separation phenomena are relevant in particular for the reliable product performance of the detergent portion unit if the receiving chamber K min is filled with very small amounts of active substances, the receiving chamber K min in other words has a small absolute inner volume, or if the inner volume of the receiving chamber K min makes up only a small proportion of the total inner volume of the detergent portion unit, the receiving chamber K min in other words has a small relative inner volume.The particle size of the powder P min located in the receiving chamber K min can vary within wide ranges. Embodiments have proven to be suitable for the optics of the detergent portion unit in which the powder P min has an average particle size of 5 μm to 150 μm.In order to avoid dust contamination during the production of the detergent portion units, it is advantageous in comparison thereto if the powder P min has an average particle size of 300 μm to 800 μm.The powder P min has a maximum particle size of 2000 μm.The selection of the active substance A min is not subject to any fundamental restrictions. As mentioned above, however, particular preference is given to active substances A min which make up a small absolute or relative proportion by volume of the detergent preparation present in the detergent portion. Preferred laundry detergent portion units therefore contain the active substance A min only in the receiving chamber K min, while the further receiving chambers are free of the active substance A min.Active substances A min from the group of solid washing or cleaning auxiliaries are preferred.Owing to their wide range of action, their ease of metering and their low proportion by weight of customary laundry detergent compositions, the use of active substances A min from the group of the polymers is particularly preferred.Particularly preferred active substance classes of the active substance A min are the soil release polymers, dye transfer inhibitors, graying inhibitors and antiredeposition agents.Soil release active ingredients are components which have a positive effect on oil and grease washability from textiles. This effect is particularly evident when a textile is soiled which has already been washed several times beforehand with an agent containing this oil- and fat-dissolving component. Preferred soil release active compounds include, for example, nonionic cellulose ethers such as methylcellulose and methylhydroxypropylcellulose having a proportion of methoxyl groups of 15 to 30% by weight and of hydroxypropoxyl groups of 1 to 15% by weight, in each case based on the nonionic cellulose ethers, and the polymers of phthalic acid and / or terephthalic acid or derivatives thereof known from the prior art with monomeric and / or polymeric diols, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or nonionically modified derivatives thereof. Preference is also given to anionic or nonionic polyesters of polypropylene terephthalates. Such are commercially available, for example, under the trade name Texcare ®. In summary, preference is given to detergent portion units in which the active substance A min is selected from the group of the polymers of phthalic acid and / or of terephthalic acid or derivatives thereof with monomeric and / or polymeric diols, preferably from the group of the polymers of ethylene terephthalates and / or polyethylene glycol terephthalates and / or polypropylene terephthalates or anionically and / or nonionically modified derivatives thereof, particularly preferably from the group of the anionic or nonionic polyesters of polypropylene terephthalates.It is preferred that the color transfer inhibitor is a polymer or copolymer of cyclic amines such as vinylpyrrolidone and / or vinylimidazole. Polymers suitable as a color transfer inhibitor include polyvinyl pyrrolidone (PVP), polyvinylimidazole (PVI), copolymers of vinyl pyrrolidone and vinylimidazole (PVP / PVI), polyvinylpyridine N-oxide, poly-N-carboxymethyl-4-vinylpyridium chloride, polyethylene glycol modified copolymers of vinyl pyrrolidone and vinylimidazole, and mixtures thereof. Particular preference is given to using polyvinylpyrrolidone (PVP), polyvinylimidazole (PVI) or copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI) as dye transfer inhibitor. The polyvinylpyrrolidones (PVP) used preferably have an average molecular weight of from 2,500 to 400,000 and are commercially available from ISP Chemicals as PVP K 15, PVP K 30, PVP K 60 or PVP K 90 or from BASF as Sokalan® HP 50 or Sokalan® HP 53. The copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI) used preferably have a molecular weight in the range from 5,000 to 100,000 g / mol. A PVP / PVI copolymer is commercially available, for example, from BASF under the designation Sokalan® HP 56.Graying inhibitors have the task of keeping the dirt detached from the textile fiber suspended in the liquor. Water-soluble colloids, usually of organic nature, are suitable for this purpose, for example starch, glue, gelatin, salts of ethercarboxylic acids or ethersulfonic acids of the starch or of the cellulose or salts of acidic sulfuric esters of the cellulose or of the starch. Water-soluble polyamides containing acidic groups are also suitable for this purpose. Furthermore, starch derivatives other than those mentioned above may be used, for example aldehyde starches. Preference is given to using cellulose ethers, such as carboxymethylcellulose (Na salt), methylcellulose, hydroxyalkylcellulose and mixed ethers, such as methylhydroxyethylcellulose, methylhydroxypropylcellulose, methylcarboxymethylcellulose and mixtures thereof.Suitable antiredeposition agents are, in particular, (co)polymers based on polyethyleneimine, polyvinyl acetate and polyethylene glycol, preferably in mixtures with antiredeposition agents.Particularly preferred detergent portion units comprise an active substance A min selected from the group of carboxymethylcelluloses, nonionic cellulose ethers, polyalkoxylated polyethyleneimines and (co)polymers of phthalic or terephthalic acid.In an alternative embodiment, the active substance A min is selected from the group of textile-softening clays. A suitable textile-softening clay is, for example, a smectite clay. Preferred smectite clays are Beidellite clays, hectorite clays, laponite clays, montmorillonite clays, nontronite clays, saponite clays, sauconite clays and mixtures thereof. Montmorillonite clays are the preferred softening clays. Bentonites contain mainly montmorillonites and can serve as a preferred source for the fabric softening clay. The bentonites can be used as powders or crystals. Particular preference is given to the use of textile-softening clays from the group of montmorillonite clays.Preference is furthermore given to the use of an active substance A min selected from the group of the organic acids and their salts, preferably from the group of citric acid and its salts.The powder P min may contain a colorant. For example, all particles of the powder Pmin can be colored. However, only a part of the particles of the powder can also be colored.The structure of some particularly preferred detergent portion units can be found in the following tables (details of the internal volume of the receiving chambers in ml).
