Definitions
- the invention relates to a method for producing detergent tablets containing surfactants.
- Microwave technology offers another possibility for the production of detergent tablets.
- international application WO 94/25563 describes the production of washing and cleaning-active molded articles using microwave technology, which have an extremely high dissolving rate or disintegration rate.
- This technique can be used to produce so-called macrosoiids, which can usually contain up to 40% by weight of surfactants.
- one of the raw materials used in substantial quantities is a crystalline layered silicate, in particular of the type SKS-6 ® (crystalline sodium disilicate; commercial product from Hoechst AG, Germany), the surfactant content can even be up to 60% by weight.
- microwave molded articles which contain anionic surfactants in substantial amounts, for example in amounts above 10% by weight, and inorganic salts in amounts below 60% by weight are to be produced, these can be prepared according to the teaching of the earlier German application P 4429550.2 by introducing the anionic surfactants into the process in the form of one or more compounds.
- the invention therefore relates to a process for the production of detergent tablets containing surfactants, the starting materials being admixed in solid form with amorphous sodium silicate, which has a water content of less than 15% by weight, and this mixture is then molded in a manner known per se is transferred.
- the process according to the invention is characterized in that amorphous sodium silicate in solid form, which has a water content of less than 15% by weight, is added to the starting materials. It is advantageous to introduce the amorphous sodium silicate into the process as finely divided as possible, that is to say as a powder.
- the amorphous sodium silicates used in the process according to the invention are preferably silicates in the module range (molar ratio SiO 2 / Na 2 O) 1, 3 to 3.0, in particular 1.8 to 3.
- the term "amorphous" is used in the context of Invention also understood “X-ray amorphous".
- the water content of the amorphous sodium silicates used according to the invention is below 15% by weight, preferably between 0.5 and 13% by weight and in particular between 2 and 8% by weight.
- the amorphous silicates used according to the invention with a water content of less than 15% by weight can be produced, for example, according to the process of EP 542 131 by drying water glass solutions with hot air or flue gas.
- the use of dried amorphous sodium silicate is also preferred, as is described in German patent application DE 44 00 024.
- the detergent tablets produced according to the invention preferably have a proportion of dried amorphous sodium silicate, based on the total weight of the tablets, between 1 and 25% by weight, preferably between 3 and 15% by weight.
- the moldings can be obtained in a manner known per se, for example by pressing or by casting the constituents or with the aid of microwave technology.
- the moldings are produced using microwave technology.
- the premixed components are placed in a mold and pressed under pressure.
- the amount of pressure is selected depending on the desired strength of the molded body.
- the moldings can be produced by casting if all or some of the components can be converted into a liquid form, for example by melting or pressurization, and all components are stable under these conditions.
- the liquid mixture is poured into a mold and then allowed to solidify.
- the radiation leads to elevated temperatures and to the local sintering of the ingredients at the contact points, the cavities in the molded body being retained, ie complete fusion of the ingredients with one another is avoided.
- the cavities that exist between the individual ingredients before the irradiation with microwaves bring about a high porosity of the resulting shaped bodies and thus contribute to improving the dissolving properties of the shaped bodies.
- starting materials In order for local sintering of the starting materials to be possible, at least some of them must have sintering properties on the surface. For this purpose, it is necessary that the starting materials themselves or their surface contain enough water so that the contact points of the ingredients are fused by the heating of this water. Therefore, in a preferred embodiment of the present invention, starting materials are used, some of which are in hydrated form. In the context of this application, “hydrated” means “hydrated under certain conditions with regard to temperature, pressure or relative humidity of the atmosphere to which the raw material is exposed or with which the raw material is in equilibrium”.
- shaped body is not restricted to a specific spatial shape. In principle, any spatial shape is possible that can be forced onto the starting materials due to an outer container. Preference is given to tablets in a conventional sense, ie cylindrical bodies, the height of the cylinder being smaller is than its diameter
- the spatial shape of a particularly preferred embodiment of the tablet is adapted in its dimensions to the induction chamber of commercially available household washing machines, so that the tablet can be dosed directly into the induction chamber without metering aid, where it dissolves during the induction process
- Another preferred shaped body which can be produced has a plate-like or plate-like structure with alternately 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 Machine can be entered
- This principle of the "cone-shaped” tablet 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
- the individual starting materials are used in the form of compounds, that is to say pre-prepared mixtures of individual starting materials, surfactant compounds are particularly preferably used, in particular compounds containing anionic surfactants, which may also contain nonionic, amphoteric or kattonic surfactants.
- the surfactant compounds usually have a surfactant content of at least 10% by weight, preferably at least 40% by weight, particularly preferably 60 to 95% by weight, based on the compound.
- the tablets which have a mutually negative effect
- the layer structure of the tablets can take place in a stack-like manner, with the inner layer (s) already loosening at the edges of the tablet when the outer layers have not yet been completely dissolved, but it is also possible to completely encase the inner layer (s) ) can be achieved by the outer layer (s), which leads to the premature dissolution of components of the inner layer (s).
- a tablet 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 tablet in the form of a tablet, the two outer layers and in the case of the envelope Tablet the outermost layers, however, are free from peroxy bleach. Furthermore, it is also possible to spatially separate peroxy bleaching agents and any bleach activators and / or enzymes present in a tablet. Such multilayer tablets have the advantage that they can be used not only via a dispenser or via a metering device which is added to the washing liquor; rather, it is also possible in such cases to put the tablet in direct contact with the textiles in the machine without fear of bleaching and the like.
- compounds containing anionic surfactants which contain various anionic surfactants - for example alkyl sulfates and alkylbenzenesulfonates and / or soap or alkyl sulfates and sulfated fatty acid glycerol esters - and / or anionic surfactants in combination with nonionic surfactants - for example alkyl sulfates and ethoxylated fatty alcohols or alkyl sulfonates, alkylbenzene sulfates, ethoxylated fatty alcohols and / or alkyl glycosides or alkyl sulfates, soap, ethoxylated fatty alcohols and glucamides - contain. These are preferably compounds which contain anionic surfactants and nonionic surfactants in a weight ratio of 10: 1 to 1:10.
- Another preferred embodiment of the invention provides that at least two different types of compounds are used in the process.
- At least 15% by weight, preferably 35% by weight and in particular at least 50% by weight of the total formulation of the laundry detergent or cleaning product tablets produced consist of one or more different types of compounds. It can be particularly advantageous to use at least 75% by weight and up to 100% by weight of the total formulation as a compound, which has optionally been post-treated.
- conventional and commercially available washing or cleaning agents which contain at least one compound containing anionic surfactants can be converted into moldings in the manner according to the invention. Examples of this are spray-dried detergents with bulk densities of about 300 to 600 g / l, which preferably contain 5 to 40% by weight of anionic surfactants in the spray-dried proportions.
- Non-ionic surfactants are to be mentioned here as preferred liquid constituents, for example finely divided zeolites, silicas, sulfates and / or calcium stearates as powdering agents.
- spray-dried granules containing anionic surfactants are present in addition to spray-dried or granulated compounds which consist of carrier materials such as zeolite, crystalline sheet silicates, polymeric polycarboxylates, carbonates and optionally also silicates and with liquid to paste-like or wax-like ingredients such as nonionic surfactants and / or foam inhibitors or conventional textile softeners are impregnated.
- carrier materials such as zeolite, crystalline sheet silicates, polymeric polycarboxylates, carbonates and optionally also silicates and with liquid to paste-like or wax-like ingredients such as nonionic surfactants and / or foam inhibitors or conventional textile softeners are impregnated.
- the shaped articles produced according to the invention are aftertreated with further substances, in particular ingredients of washing or cleaning agents.
- further substances in particular ingredients of washing or cleaning agents.
- substances that are not stable under the conditions of manufacture such as high temperatures or pressures.
- these include, for example, enzymes and perfumes.
- enzymes and perfumes When using microwave technology it may be advantageous for enzymes to be irradiated because of the better possible temperature control or the lower temperature load of the overall mixture.
- the moldings produced according to the invention are provided with a coating of hydrated salts, such as sodium acetate trihydrate or the di-, hepta- or dodecahydrate of disodium hydrogen phosphate, according to the teaching of European patent application EP-A-0 002 293.

- a tablet was produced from the compounds, powders and liquids listed below in accordance with the teaching of international patent application WO 94/25563.
- Granulated compounds were used as starting materials (Table 1), which were mixed in a mixer to form a homogeneous overall mixture, which was then converted into a shaped body filled and pre-pressed for 10 seconds with a pressure of 13 N / cm 2 (the force exerted on the circular area was 35 N on an area of 2.7 cm 2 ).
- the microwave irradiation was then carried out at 2450 MHz and 250 watts. 5 seconds
- the tablets had a diameter of 4 cm, a height of 2.5 cm and a weight of 20 g.
- the amorphous sodium silicate (module 2.0) used had a water content of 13% by weight (measured as glow loss, produced according to the Method of DE 44 00 024)
- the compressive strength of the tablets was measured with a SCHLEUNIGER tablet hardness test device model 6D
- a shaped body (20 g) was added to dry laundry (3.5 kg) in a conventional metering device in a washing machine (type Miele Novotronic W 918). After water had run in, the metering device was weighed with the shaped body. A colored washing program was then carried out (111 water, 16 ° C.). After 5 and 10 minutes the washing program was interrupted and the metering device with the remnants of the shaped body was weighed. The differences from the first measurement of the dosing device with molded body can be found in Table 1.
- Tablets were produced by the same procedure as in Example 1.
- the amorphous sodium silicate (module 2.0) had a water content of 8% by weight (measured as loss on ignition, produced by the process of DE 44 00 024).
- the tablets produced in this way had a compressive strength of at least 20 N / cm 2 and disintegrated in cold water after no more than 60 seconds. (To measure the rate of disintegration, the tablets were placed in a beaker with 750 ml of water and the time at which the tablets had disintegrated was determined).
- the recipes can be found in Table 2.
