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 filled with a melt. 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. During machine filling of receiving chambers with small volumes with liquids, the liquid can escape over the edge of the receiving chamber into the region of the later sealing at high machine speeds and high filling degrees of the receiving chambers due to inertia phenomena after filling. This contamination of the sealing region makes the subsequent leak-proof sealing of the receiving chamber more difficult or impossible.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 an active substance composition A min which liquifies at a temperature above 30° C. and fills the internal volume of the receiving chamber K min to at least 70% by volume.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.

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 active material composition A min fills the internal volume of the receiving chamber K min preferably to an extent of at least 75% by volume, preferably to an extent of at least 80% by volume and in particular to an extent of at least 85% by volume.

Corresponding active material compositions A min are distinguished by a solidification behavior suitable for industrial scale processing.The active substance composition A min can be present as a single substance or as an active substance mixture. While in the case of the use of an individual substance, this individual substance must have the liquefaction temperature characterizing the subject matter of the invention, in the case of active substance mixtures liquifiable carriers can be combined with further active substances, for which reason the latter embodiment offers a greater number of design options and is preferred.When liquifiable mixture is used, the active substances can be present dissolved or dispersed in the carrier. The use of such a carrier-active material composition makes it possible, for example, to fill solid active materials, for example solid polymeric active materials, with low dust content into the receiving chamber K min. By using corresponding carrier materials, the dispersed active substances in the receiving chamber K min surrounded by a water-soluble film are additionally protected from environmental influences such as moisture access or migration of active substances from adjacent receiving chambers. A corresponding embodiment thus offers advantages in particular when filling hygroscopic active substances into the receiving chamber K min or when filling mutually incompatible active substances in adjacent receiving chambers.In summary, a preferred laundry detergent portion unit has an active material composition A min which comprises i) a carrier material which liquifies above 30° C., preferably above 40° C. or above 55° C., preferably at a temperature in the range from 55° C. to 200° C., preferably from 75° C. to 150° C. and in particular from 90° C. to 130° C.; ii) a solid particulate active material dispersed in the carrier material.The rheological properties of the active composition A min and hence the processibility thereof can be influenced, among other constituents, by the addition of gelling agents.
