Definitions

  • 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 detergents: they are easier to dose and handle and, thanks to their compact structure, have advantages for storage and transportation. 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.
  • Anionic surfactants used are, for example, those of the sulfonate and sulfate type.
  • the surfactants of the sulfonate type are preferably C - 13 - alkylbenzenesulfonates, olefin sulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates of the type obtained, for example, from C 2-0 8 monoolefins with an end or internal double bond by sulfonation gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.
  • Preferred detergent tablets contain 0.5 to 10% by weight, preferably 3 to 7% by weight and in particular 4 to 6% by weight of one or more disintegration auxiliaries, in each case based on the molded article weight.
  • the present invention therefore also relates to a process for the production of detergent shaped bodies by shaping molding a particulate premix, the finely divided solubilizer with a solubility of more than 200 g per liter of water at 20 ° C. in amounts of 0.5 to Contains 20 wt .-%, based on the premix, wherein at least 30 wt .-% of the particles of the solubilizers have particle sizes below 200 microns.
  • the premix contains the finely divided solubilizer or solubilizers in amounts of 1 to 15% by weight, preferably 1.5 to 10% by weight and in particular 2 to 5% by weight, based on the molded body weight, contains and have at least 35% by weight, preferably at least 40% by weight, particularly preferably at least 45% by weight and in particular at least 50% by weight of the particles of the solubilizers, particle sizes below 200 ⁇ m.
  • Preferred detergent tablets in the context of the present invention are obtained by squeezing a particulate premix consisting of at least one surfactant-containing granulate and at least one subsequently admixed powdery component.
  • the granules containing surfactant can be produced by conventional industrial granulation processes such as compacting, extrusion, mixer granulation, pelletization or fluidized bed granulation. It is advantageous for the later detergent tablets if the premix to be ve ⁇ resses has a bulk density that comes close to the usual compact detergent. In particular, it is preferred that the premix to be ve ⁇ ress has a bulk density of at least 500 g / 1, preferably at least 600 g / 1 and in particular above 700 g / 1.
  • the surfactant granules preferably also contain carriers which particularly preferably come from the group of builders.
  • Particularly advantageous processes are characterized in that the surfactant-containing granules contain anionic and / or nonionic surfactants and builders and have total surfactant contents of at least 10% by weight, preferably at least 20% by weight and in particular at least 25% by weight.
  • the premix can be "powdered” with finely divided surface treatment agents. This can be of advantage for the nature and physical properties of both the premix (storage, pressing) and the finished detergent tablets.
  • Finely divided powdering agents are well known in the art, mostly zeolites, silicates or other inorganic salts being used.
  • the premix is preferably “powdered” with finely divided zeolite, zeolites of the faujasite type being preferred.
  • zeolite of the faujasite type denotes all three zeolites which form the faujasite subgroup of the zeolite structure group 4 (compare Donald W. Breck: “Zeolite Molecular Sieves”, John Wiley & Sons, New York , London, Sydney, Toronto, 1974, page 92).
  • zeolite Y and faujasite and mixtures of these compounds can also be used, the pure zeolite X being preferred.
  • bleaching agents that serve as bleaching agents and provide water H O
  • sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance.
  • Other bleaching agents that can be used are, for example, sodium percarbonate, peroxypyrophosphates, citrate perhydrates and HO-providing peracidic salts or peracids, such as perbenzoates, peroxophthalates, diperazelaic acid, phthaloiminoperacid or diperdodecanedioic acid.
  • Even when using the bleaching agents it is possible to dispense with the use of surfactants and / or builders, so that pure bleach tablets can be produced.
  • Preferred representatives are (a) peroxybenzoic acid and its ring-substituted derivatives, such as alkylperoxybenzoic acids, but also peroxy- ⁇ -naphthoic acid and magnesium monophthalate, (b) the aliphatic or substituted aliphatic peroxyacids, such as peroxylauric acid, peroxystearic acid, ⁇ -phthalimidopercapid [Phthaloiminoperoxyhexanoic acid (PAP)], o-carboxybenzamidoperoxycaproic acid, N-nonenylamidoperadipic acid and N-nonenylamidopersuccinate, and (c) aliphatic and araliphatic peroxydicarboxylic acids, such as 1,12-diperoxycarboxylic acid, 1, 9-diperoxyacelic acid oxyacid, 2-decyldiperoxybutane-1,4-diacid, N, N-terephthaloyl-di
  • bleach catalysts can also be incorporated into the moldings.
  • These substances are bleach-enhancing transition metal salts or transition metal complexes such as, for example, Mn, Fe, Co, Ru or Mo salt complexes or carbonyl complexes.
  • Mn, Fe, Co, Ru, Mo, Ti, V and Cu complexes with N-containing tripod ligands as well as Co, Fe, Cu and Ru amine complexes can also be used as bleaching catalysts.
  • the detergent tablets can also contain components that positively influence the oil and fat washability from textiles (so-called soil repellents). This effect becomes particularly clear when a textile is soiled that has already been washed several times beforehand with a detergent according to the invention which contains this oil and fat-dissolving component.
  • the preferred oil- and fat-dissolving components include, for example, nonionic cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with a proportion of methoxyl groups of 15 to 30% by weight and hydroxypropoxyl groups of 1 to 15% by weight, in each case based on the nonionic cellulose ether, and the polymers of phthalic acid and / or terephthalic acid or their derivatives known from the prior art, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or nonionically modified derivatives thereof. Of these, the sulfonated derivatives of phthalic acid and terephthalic acid polymers are particularly preferred.
  • Dyes and fragrances are added to the detergent tablets according to the invention in order to improve the aesthetic impression of the products and, in addition to the softness, to provide the consumer with a visually and sensorially "typical and unmistakable" product.
  • perfume oils or fragrances individual fragrance compounds, e.g. the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type are used. Fragrance compounds of the ester type are e.g.
  • the linear alkanals with 8-18 C atoms citral, citronellal, citronellyloxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, lilial and bourgeonal, to the ketones e.g. the Jonone, cc-isomethylionon and methyl-cedrylketone, to the alcohols anethol, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and Te ⁇ ineol, to the hydrocarbons belong mainly the Te ⁇ ene like Limonen and Pinen. However, preference is given to using mixtures of different fragrances which together produce an appealing fragrance.
  • perfume oils can also contain natural fragrance mixtures as are available from plant sources, e.g. Pine, Citras, Jasmine, Patchouly, Rose or Ylang-Ylang oil. Also suitable are muscatel, sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, lentil flower oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil as well as orange blossom oil, neroliol, orange peel oil and sandalwood oil.
  • the dye content of the detergent tablets according to the invention is usually less than 0.01% by weight, while fragrances can make up up to 2% by weight of the total formulation.
  • the agents according to the invention can be colored with suitable dyes.
  • Preferred dyes the selection of which is not difficult for the person skilled in the art, have a high storage stability and insensitivity to the other ingredients of the compositions and to light, and no pronounced substantivity to textile fibers, in order not to dye them.
  • the molded articles according to the invention are first produced by dry mixing the constituents, which can be wholly or partially pregranulated, and then providing information, in particular feeding them into tablets, whereby conventional methods can be used.
  • the premix is compacted in a so-called die between two punches to form a solid compact. This process, which is briefly referred to below as the tableting line, is divided into four sections: metering, compression (elastic deformation), plastic deformation and ejection.
  • the premix is introduced into the die, the filling quantity and thus the weight and the shape of the molded body being formed being determined by the position of the lower punch and the shape of the pressing tool.
  • the constant dosing, even at high mold throughputs, is preferably achieved by volumetric dosing of the premix.
  • the upper punch touches the premix and lowers further in the direction of the lower punch.
  • the particles of the premix are pressed closer together, the void volume within the filling between the punches continuously decreasing. From a certain position of the upper punch (and thus from a certain pressure on the premix), the plastic deformation begins, in which the particles flow together and the molded body is formed.
  • these cam tracks are supported by additional low-pressure pieces, low-tension rails and lifting tracks.
  • the die is filled via a rigidly arranged feed device, the so-called filling shoe, which is connected to a storage container for the premix.
  • the pressure on the premix can be individually adjusted via the press paths for the upper and lower punches, the pressure being built up by rolling the punch shaft heads past adjustable drape rollers.
  • the molded body can be manufactured in a predetermined spatial shape and a predetermined size. Practically all sensibly manageable configurations come into consideration as the spatial form, for example the design as a board, the rod or bar form, cubes, cuboids and corresponding spatial elements with flat side surfaces and in particular cylindrical configurations with a 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. However, it is also possible to form compacts which combine a plurality of such mass units in one compact, the portioned smaller units being easy to separate, in particular by 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 manufactured has a plate-like or panel-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 "bar-shaped" shaped body detergent can also be realized 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 performance properties of the molded articles.
  • 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.
  • the bodies to be coated can be coated with, for example aqueous solutions or emulsions are sprayed, or else a coating is obtained via the process of melt coating.
  • Another object of the present invention is the use of finely divided solubilizers, which have a solubility of more than 200 g per liter of water at 20 ° C, with at least 30 wt .-% of the particles of the solubilizers have particle sizes below 200 microns to improve physical properties of laundry detergent and cleaning product.
  • Granulation in a 50-liter ploughshare mixer from Lödige produced granules containing tensides (for composition, see Table 1), which was used as the basis for a particulate premix. Following the granulation, the granules were dried in a fluidized bed apparatus from Glatt at a supply air temperature of 60 ° C. over a period of 30 minutes. After drying, fine particles ⁇ 0.4 mm and coarse particles> 1.6 mm were screened off.
  • the hardness of the tablets was measured by deforming the tablet until it broke, the force acting on the side surfaces of the tablet and the maximum force which the tablet withstood being determined.
  • Table 5 shows that the disintegration times of laundry detergent and cleaning agent shaped bodies are significantly reduced by the use of the finely divided solubilizer according to the invention.
