Definitions
- the present invention is in the field of compact moldings which have washing and cleaning properties.
- the invention relates to detergent tablets such as, for example, detergent tablets, dishwasher tablets, stain remover tablets or water softening tablets for use in the home, in particular for machine use.
- Detergent tablets are widely described in the prior art and are becoming increasingly popular with consumers because of the simple dosage. Tableted detergents and cleaning agents have a number of advantages over powdered ones: They are easier to dose and handle and, thanks to their compact structure, have advantages in terms of storage and transport. Detergent tablets are therefore also comprehensively described in the patent literature.
- a problem that occurs again and again when using shaped articles which are active in washing and cleaning is the insufficient rate of disintegration and dissolution of the shaped articles under conditions of use. Since sufficiently stable, that is to say shape and break-resistant molded articles can only be produced by relatively high compression pressures, there is a strong compression of the molded article components and consequent delayed disintegration. gration of the shaped body in the aqueous liquor and thus to a slow release of the active substances in the washing or cleaning process.
- wick mechanism water is sucked into the interior of the molded body through the disintegration accelerator and thereby loosens the binding forces between the particles, which also leads to the disintegration of the molded body.
- the repulsion mechanism also differs from this in that the particles released by the water sucked into the pores repel each other by the resulting electrical forces.
- a fundamentally different mechanism is based on the "effervescent tablets", which contain active substances or active substance systems which, when in contact with water, release gaseous substances which cause the shaped body to burst. Additionally there is the use of hydrophilizing agents which ensure better wetting of the compressed particles in water and thus faster disintegration is known.
- EP-B-0 396 335 (Beecham Group PLC) discloses chewable tablets which, in addition to 1 to 30% by weight of a effervescent system, contain 0.5 to 20% by weight of lemon, wine, adipine and fumarate - or maleic acid and 0.5 to 30% by weight Na, K or Ca (hydrogen) carbonate or Na glycine carbonate additionally 5 to 30% by weight of a disintegrant such as (modified) cellulose, polyvinylpyrrolidone or starch contain keglycolate.

Despite the use of two disintegration systems, these tablets are advertised as active ingredient carriers with delayed release.

- disintegrants which contain a swelling, gel-forming polymer (sodium alginate, carrageenan, polyethylene oxide) and a CO 2 -generating agent Bubble system included, covered.

- the use of a effervescent system in detergent tablets does not lead to the desired rapid disintegration; rather, the effervescence and disintegration effect known from conventional effervescent tablets initially sets in, but comes to a standstill again after a short time, and the tablet is then no longer broken down.
- the above-mentioned detergent and cleaning agent ingredients form a water-impermeable layer after a short time, which prevents the water from penetrating into the tablet and thus preventing it from disintegrating.

- the invention relates to a process for the production of the detergent tablets according to the invention by squeezing a particulate detergent and cleaning agent, comprising surfactant (s), builder and, if appropriate, further detergent and detergent components, the detergent and Detergent continues
- components a) and b) can both be compounded with other ingredients of the detergent and cleaning agent or can be mixed separately.
- the particulate premix to be ve ⁇ ress can be in the form of a pure powder mixture in which components a) and b) are present, but it is preferred that individual raw materials are introduced into the premix in pretreated, in particular precompressed, form.
- the disintegration aids are preferably introduced into the premix in the form of granules, pellets, compactates or extrudates.
- surfactants which are introduced into the premix in the form of advantageously builder-containing particles, which can be obtained by spray drying, granulation, pelleting, compacting or extrusion.
- the particulate detergent and cleaning agent composition is pressed at temperatures below 30 ° C. and pressing forces below 15 N / cm 2 .
- the actual production of the molded article according to the invention is carried out first by dry mixing the components, which may be wholly or partially pre-granulated, and then providing information, in particular compresses to tablets, using conventional methods (for example, as in the conventional patent literature on tablets, especially on the Detergent or cleaning agent area, in particular as described in the above-mentioned patent applications and the article "Tablett michtechnik: Stand dertechnik", S ⁇ FW-Journal, 122nd year, pp. 1016-1021 (1996)).
- the molded body can be manufactured in a predetermined spatial shape and a predetermined size. Practically all usable configurations come into consideration as the spatial shape, for example, the design as a board, the rod or bar shape, cubes, cuboids and corresponding spatial elements with flat side surfaces and, in particular, linden-shaped configurations with circular or oval cross-section.
- This last embodiment covers the presentation form from the tablet to compact cylinder pieces with a ratio of height to diameter above 1.
- the portioned compacts can each be designed as separate individual elements that correspond to the predetermined dosage of the detergents and / or cleaning agents. It is also possible, however, to form compacts which connect a plurality of such mass units in one compact, the portioned smaller units being easy to separate, in particular by predetermined predetermined breaking points.
- the portioned compacts as tablets, in cylinder or cuboid form can be expedient, with a diameter / height ratio in the range from about 0.5: 2 to 2: 0.5 is preferred.
- Commercial hydraulic presses, eccentric presses or rotary presses are suitable devices, in particular for the production of such pressed articles.
- the spatial shape of another embodiment of the molded body is adapted in its dimensions to the detergent dispenser of commercially available household washing machines, so that the molded body can be metered directly into the dispenser without metering aid, where it dissolves during the dispensing process.
- the detergent tablets without problems using a metering aid and is preferred in the context of the present invention.
- Another preferred molded body that can be produced has a plate-like or plate-like structure with alternating thick long and thin short segments, so that individual segments of this "bolt" at the predetermined breaking points, which represent the short thin segments, are broken off and into the
- This principle of the "bar-shaped" shaped body detergent can also be implemented in other geometric shapes, for example vertically standing triangles, which are connected to one another only on one of their sides along the side.
- the various components are not pressed into a uniform tablet, but that shaped bodies are obtained which have several layers, that is to say at least two layers. It is also possible that these different layers have different dissolving speeds. This can result in advantageous application properties of the molded body.
- the layer structure of the molded body can take place in a stack-like manner, with the inner layer (s) already loosening at the edges of the molded body when the outer layers have not yet been completely removed, but it is also possible for the inner layer (s) to be completely encased ) can be achieved by the layer (s) lying further outwards, which leads to the premature dissolution of components of the inner layer (s).
- a molded body consists of at least three layers, that is to say two outer and at least one inner layer, at least one of the inner layers containing a peroxy bleaching agent, while in the case of the stacked molded body, the two outer layers and in the case of the molded body however, the outermost layers are free of peroxy bleach. Furthermore, it is also possible to spatially separate peroxy bleaching agents and any bleach activators and / or enzymes that may be present in a molded body.
- Such multilayer molded bodies have the advantage that they can be used not only via a dispensing chamber or via a metering device which is added to the washing liquor; rather, in such cases it is also possible to put the molded body into direct contact with the textiles in the machine without the risk of bleaching from bleaching agents and the like. Similar effects can also be achieved by coating individual constituents of the detergent and cleaning agent composition to be treated or the entire molded body.
- the bodies to be coated can be sprayed with aqueous solutions or emulsions, for example, or by the process of melting. get a coating.
- the moldings according to the invention in particular the detergent molds and bleach moldings which have been poorly disintegrating and poorly soluble up to now, have excellent disintegration properties due to the content of water-insoluble, swellable disintegration aid and effervescent system ⁇ components a) and b) ⁇ .
- This can be tested, for example, under critical conditions in a conventional household washing machine (use directly in the washing liquor using a conventional dosing device, delicate washing program or colored laundry, washing temperature at most 40 ° C).
- a washing method is therefore claimed, the molded body being introduced into the washing liquor via the induction device of the household washing machine.
- the dissolving times of the molded articles in the washing machine are preferably less than 8 minutes and in particular less than 5 minutes.
- a further embodiment of the invention claims a washing method in which the molded body - optionally with a metering aid - is placed directly on the laundry which is located in the drum of a household washing machine.
- the molded body can advantageously be added directly to the laundry, ie without additional metering aid; the use of known dosing aids such as bags, sachets, plastic containers or the like is also possible without any problems. Examples
- the detergent tablets 1 and 2 according to the invention and comparative examples 3 and 4 were produced, which had a composition according to Table 1.
- the comparative examples contained either no component a) (example 3) or no component b) (example 4), small amounts of Na 2 CO 3 being used as builders.
- the hardness of the tablets was measured by deforming the tablet to fracture, the force acting on the side surfaces of the tablet and the maximum force that the tablet was able to withstand.
- the tablet was placed in a beaker with water (600 ml of water, temperature 30 ° C.) and the time until the tablet disintegrated completely.
