Definitions
- the present invention relates to a detergent portion unit, comprising a gel body and a rigid enveloping substance at least partially covering the gel body.
- the application also relates to a method for producing this detergent portion unit and a washing method for textiles or crockery using such a detergent portion unit.
- water-soluble polymers are generally formed into receiving chambers, which are then filled with a detergent or cleaning agent and finally sealed.
- the receiving chambers can be made, for example, from water-soluble polymer films by deep-drawing processes.
- a water-soluble polymer is injection molded into a receptacle.
- the water-soluble packaging material used to package the filled detergent portion units is generally hygroscopic.
- the tendency and ability of the packaging to absorb water can result in portion units adhering to the surfaces of machines or packaging materials and being unable to be optimally conveyed, or in adjacent portion units, for example in a common outer packaging, glue together.
- the powdering of the water-soluble detergent portion units in turn requires an additional process step.
- the washing performance provided by the detergent portion unit is directly related to the dissolving properties of the portion unit. Precisely in view of the increasing use of cold washing processes, it is preferable to keep the thickness of the water-soluble film material contained in the detergent portion unit as small as possible in order to accelerate the dissolution process. At the same time, however, the reduction in the thickness of the surrounding film material results in reduced mechanical stability of the portion units. Overcoming this apparent dichotomy of mechanical stability and dissolution rate using water-soluble film-packaged detergent dosage units is still a relevant aspect in the development of water-soluble detergent portion units.
- Detergent tablets offer an alternative to the sachets described above, in which however adequate mechanical stability and high dissolution rate are incompatible in a similar way as in the case of sachets.
- the application was based on the object of providing detergent portion units that can be produced using simplified processes, have high product and storage stability, can be made up easily using very small amounts of packaging materials and are an appealing olfactory, visual and/or haptic appeal.
- the detergent portion units should have a high product performance and be easy and safe to handle for the consumer.
- a detergent portion unit is suitable for solving these tasks, comprising a) a dimensionally stable gel body b) an enveloping substance in the form of a shaped body different from the dimensionally stable gel, which partially covers the surface of the dimensionally stable gel body, with i) the enveloping substance on its outer surface n > 1 points whose surface normals pass both through the shell substance and through the rigid gel body and meet at an angle of 360% and ii) the aspect ratio of the distance running from these surface normals inside the shell substance to the distance running from these surface normals inside the gel body 2: 3 to 1:14, preferably 1:2 to 1:10.
- the term detergent portion unit describes a form of supply in which a measured portion of a detergent or cleaning agent is present.
- Detergent portion units therefore designate both forms of supply for textile laundry and forms of supply for cleaning hard surfaces such as ceramics, glass, metal or tiles.
- the detergent portion unit preferably weighs from 14 g to 42 g, preferably from 20 g to 38 g, in particular from 24 g to 34 g.
- the detergent portion unit according to the invention comprises a dimensionally stable gel and a specific coating substance which at least partially covers this gel.
- Gel bodies are bodies that exhibit elastic deformation behavior under the action of force. Objects are considered dimensionally stable if they have an inherent dimensional stability that enables them to assume a non-disintegrating three-dimensional shape under the usual conditions of manufacture, storage, transport and handling by the consumer, with this three-dimensional shape also changing over longer periods under the conditions mentioned Time, preferably 4 weeks, particularly preferably 8 weeks and in particular 32 weeks, not changed, i.e. under the usual conditions of production, storage, transport and handling by the consumer in the spatial-geometric shape caused by the production , that is, does not flow.
- Time preferably 4 weeks, particularly preferably 8 weeks and in particular 32 weeks
- a “molding” is a single body that is self-stabilizing in its imposed shape.
- This dimensionally stable body is formed from a molding material (e.g. a composition) by bringing this molding material into a predetermined shape in a targeted manner, e.g. by pouring a liquid composition into a mold and then curing the liquid composition or by compressing a particulate premix, for example in as part of a tableting process.
- a molding material e.g. a composition
- the three-dimensional form of the gel body can in principle be freely selected; its side surfaces can, for example, be convex, concave or planar. At the same time, however, certain spatial configurations have proven to be particularly advantageous against the background of the producibility, storage and use of the gel bodies.
- the gel body has a flat underside, the largest diagonal of which is greater than the height of the gel body.
- these bodies can also be packaged in a simple and space-saving manner and are suitable for dosing via the dosing or dispensing chambers of electronic cleaning devices. It is preferred if the Gel body has a flat underside, the largest diagonal of which is 1.5 times, preferably more than 2 times, the height of the gel body.
- the underside of the gel body has no corners.
- Preferred gel bodies are therefore characterized by oval undersides or alternatively by ellipsoidal or round, preferably round, undersides.
- Corresponding gel bodies with a non-angular underside are also preferred by many consumers because of their appearance.
- those gel bodies are preferred which have an underside and an upper side which are connected to one another by a cylindrical lateral surface.
- angular undersides are advantageous since such gel bodies can be cut up without leaving residues and can be packed in a space-saving manner.
- preferred gel bodies therefore have angular undersides, in particular triangular, quadrangular or hexagonal undersides.
- the gel bodies have an upper side that is plane-parallel to the underside.
- the gel body has a bottom and a top which have the same geometric shape, with the bottom and the top having the same surface area.
- corresponding gel bodies can be produced in a simple manner, for example by casting plates and then cutting up the plates to form individual gel bodies.
- these gel bodies can be spatially aligned in a simpler manner than gel bodies with a lower body symmetry in any subsequent process steps, during packaging or use by the user due to the geometric identity of the bottom and top. This applies in particular to gel bodies which at the same time have an upper side which is plane-parallel to the underside.
- gel bodies are circular cylinders, elliptical cylinders, parallelepipeds, rhombohedrons, straight or oblique prisms, cuboids or cubes.
- the group of circular cylinders and elliptical cylinders includes the vertical circular cylinders and elliptical cylinders as well as the oblique circular cylinders and elliptical cylinders.
- Gel bodies in the form of vertical circular cylinders, vertical elliptical cylinders, right prisms, right parallelepipeds or cubes are preferred because of their simple production by separation from a plate.
- the gel body has a bottom and a top which have the same geometric shape, with the bottom and the top having different surface areas.
- Corresponding gel bodies can be preferred due to their attractive appearance or their optimized fit, while at the same time being comparatively easy to produce.
- Examples of such gel bodies are circular cylinders or elliptical cylinders with a convex or concave bottom and a flat top.
- Other examples are truncated cones or truncated pyramids.
- preferred objects of the application can be characterized as detergent portion units comprising a gel body with a bottom and a top, the area of the top being 80 to 100%, preferably 90 to 100% and in particular 98 to 100% of the bottom.
- the detergent portion units according to the invention are particularly suitable for the formulation of surfactant-containing compositions, since these compositions tend to adhere and stick to a particular extent, for example, when exposed to moisture.
- the gel body therefore contains 30 to 70% by weight, preferably 40 to 60% by weight and in particular 45 to 55% by weight of surfactant.
- the gel bodies For the manufacturability and the subsequent dissolving power of the gel bodies, it has proven to be advantageous if they contain 15 to 35% by weight, preferably 20 to 30% by weight, of an aqueous-organic solvent. Preferred gel bodies also contain dye.
- Preferred detergent dosage units comprise a transparent gel body.
- Those gel bodies are referred to as “transparent” which have a transmission in the wavelength range from 410 to 800 nm at at least one wavelength, preferably at 600 nm, above 20%, preferably above 30% and in particular above 35%.
