Definitions

  • Machine dishwashing generally consists of a pre-rinse cycle, a cleaning cycle, one or more intermediate rinse cycles, a rinse cycle and a drying cycle. This applies to machine washing in the home as well as in business.
  • HGSM HGSM
  • the pre-clearing zone corresponds in principle to the pre-rinse cycle of an HGSM.
  • the cleaning agent added to the cleaning zone is already used in the so-called pre-clearing zone to support the cleaning of the adhering food residues.
  • GGSM in which the pre-clearing zone is only operated with fresh water, but a pre-clearing zone with cleaning agent solution is more effective than pre-clearing with fresh water alone.
  • One or more tablets can be dosed, for example, in a free part of the cutlery basket, but also elsewhere in the machine.
  • tablet-shaped cleaning agents are adequately described in the patent literature.
  • tablets for machine dishwashing which, by pressing a powdery mixture of sodium silicate with a Na20: Si02 ratio of 1: 3.25 to 2: 1 and a water content of 0 to 20% , polymeric alkali metal phosphates, active chlorine compounds, low-foaming non-ionic surfactants compatible with the active chlorine compounds, fillers such as alkali metal carbonates, chlorides or sulfates, white paraffin oil and tablet binders, which are said to be stable in storage and transportation.
  • Such tablets are also known from DE-0S 28 57 001 which contain essentially the same constituents but one should have particularly high alkalinity, which can be achieved, inter alia, by adding alkali metal hydroxide.
  • alkalinity can be achieved, inter alia, by adding alkali metal hydroxide.
  • a high level of alkalinity is unsuitable for the use of the agents in the household, because improper handling of the agents can lead to skin irritation and also damage the decor.
  • the present invention was therefore based on the object of developing a tablet with a broad dissolving profile that already in the pre-rinse cycle of an HGSM from the incoming cold tap water at least 10% by weight is dissolved, a pH of at least 10.0 developed in the rinsing liquor and at least 65% by weight, preferably at least 70% by weight, is still available for the cleaning cycle if it is well soluble in hot water .
  • the dissolution profile here means the ratio of portions of the tablet dissolved from the usual HGSM under the conditions of the pre-rinse cycle to the entire tablet.
  • the object was achieved by uniformly composed detergent tablets with a broad dissolution profile for automatic dishwashing, containing customary alkaline components, in particular from the group of alkali metal silicates and pentaalkali metal phosphates, active chlorine compounds and tabletting aids, which are characterized in that the alkali metal silicates are composed of a mixture of sodium metasilicate and water-free silicate Sodium metasilicate and the pentaalkali phosphate consists of anhydrous pentasodium triphosphate, the weight ratio of anhydrous sodium metasilicate to nonahydrate being between 1: 0.3 to 1: 1.5.
  • the dissolution profile can be varied within wide limits by varying the ratio of sodium metasilicate, anhydrous to nonahydrate.
  • the weight ratio of anhydrous sodium metasilicate to nonahydrate is preferably between 1: 0.75 to 1: 1.2.
  • pentasodium triphosphate to sodium metasilicate in each case anhydrous, should be present in a ratio of 2: 1 to 1: 2, preferably from 1: 1 to 1: 1.7.
  • Active chlorine carriers are also common components of cleaning agents for HGSM.
  • tableting aids are added, the amounts of which can be varied.
  • the compressibility of raw material mixtures containing anhydrous sodium metasilicate depends on its particle size distribution, its production process, its weight ratio to the nonahydrate present at the same time and on the average particle size of the pentasodium triphosphate.
  • a grain fraction of the almost water-free sodium metasilicate e.g. from a sintering or melting process
  • good tableting properties of the raw material mixture can be obtained without or with only small additions of nonahydrate (to adjust the dissolution profile).
  • dust less than 0.2 mm
  • unscreened material with 20 to 100% coarser coarsely 0.8 mm
  • the nonahydrate should be used at least 1.2 times the amount of the water-free metasilicate in order to achieve comparable tablet properties .
  • Alkali metasilicate in anhydrous form and as a nonahydrate and also the preferably anhydrous pentaalkali metal phosphate were used in the form of their sodium salts. Their total amount in the mixture to be pressed was 88 to 98, preferably 95 to 97% by weight.
  • Trichloroisocyanuric acid was preferred as the active chlorine carrier, but also other known solid compounds, such as.
  • Their amounts are 0.5 to 5.0, preferably 1.0 to 2.5% by weight, based on the active chlorine content and the total tableting mixture.
  • the proportions of these tabletting aids which are safe from an application point of view in terms of their cleaning performance, can be varied beyond the ranges mentioned in order to be able to optimally compress recipe variants.
  • the sodium acetate content also affects the solubility of the tablet. Higher amounts of sodium acetate lead in particular to improved cold water solubility in the pre-rinse cycle.
  • Customary chlorine-stable colors and fragrances can also be added to the tableting mixtures.
  • the tablets can also be pressed in colored layers with otherwise the same composition.
  • the mixture of the fine-grained, anhydrous metasilicates, the corresponding nonahydrates, the triphosphates, active chlorine carriers and tabletting aids can be pressed under die lubrication, with conventional lubricants being used.
  • lubrication is carried out directly through holes in the die, by spraying the lower punch or by means of felt rings soaked in lubricant on the lower punch.
  • the raw material mixtures according to the invention with their particularly favorable compressibility properties, however, the lubrication can usually also be dispensed with.
  • the pressing conditions must be optimized with a view to setting the desired dissolution profile while at the same time having sufficient tablet hardness.
  • the flexural strength can serve as a measure of the tablet hardness (method: compare Ritschel. Die Tablette, Ed. Cantor, 1966, p. 313). Tablets with a flexural strength greater than 12 kp, preferably greater than 15 kp, are sufficiently stable under simulated transport conditions.
  • Corresponding tablet hardnesses have been achieved at compression pressures of 500 to 5,000 kp / cm2, preferably 1,000 to 1,500 kp / cm2. Higher pressures reduce the release speed. Differences in solubility can be compensated within limits for different compositions by choosing the pressure.
  • the specific weight of the compacts was between 1.2 and 2 g / cm3, preferably between 1.4 and 1.7 g / cm3.
  • the compression during the pressing process caused changes in the specific volume, that of 0.8 to 1.8 cm3 / g, preferably 1.0 to 1.4 cm3 / g to 0.5 to 0.8 cm3 / g, preferably 0.6 decreased to 0.7 cm3 / g.
  • the shape of the tablet can also influence the dissolving speed via the outer surface exposed to the H20 attack. For stability reasons, cylindrical compacts with a diameter / height ratio of 0.6 to 1.5: 1 were produced.
  • the amounts of the substance mixture to be compressed for the individual tablets can be varied as desired within technically reasonable limits. Depending on their size, 1, 2 or more tablets per machine filling are used to provide the entire cleaning process with the necessary active substance content of cleaning agent. Tablets of 20 to 30 g in weight are preferred, two of which must be used. Larger tablets are usually more sensitive to breakage and, moreover, are compressed at a lower speed, which leads to a loss of performance in the production process. With smaller tablets, the handling advantage compared to granular or powder detergents would be reduced.
  • compositions can be pressed in a known manner using commercially available eccentric presses or rotary presses.
  • the tablets can be placed in a cutlery basket of a household dishwasher before opening the pre-rinse cycle into a zone that exposes the tablets to the dissolving power of the tap water flow the automatically controlled cleaning process can be started.
  • the invention therefore also relates to the use of the detergent tablets for cleaning dishes in automatic household dishwashers, which is characterized in that the tablets are opened before the pre-wash cycle in the machine into a zone which exposes the tablets to the dissolving power of the cold tap water flow, for example by placing it in the cutlery basket, and then initiating the automatically controlled cleaning process.
  • the dishes cleaned in this way have better cleaning results for difficult soiling, such as, for example, burnt-on milk or baked oatmeal, than those treated in the conventional manner.
  • tablets with the same diameter and the same content of active substances sodium triphosphate, trichloroisocyanuric acid and sodium metasilicate, water-free were produced, which weighed between approx. 20 g and 27 g.
  • the different weights are due to the varying content of water of crystallization and tableting aids.
  • the tablet format was also varied with selected recipes.
  • the mixture was pressed on an eccentric press from Fette, type "Exacta 31".
  • the pressing tools were coated with Vulkolan. When pressed to a density of 1.58 g / cm3, tablets with a flexural strength greater than 15 kp were obtained, which dissolved to 25% by weight in the pre-rinse cycle and completely in the cleaning cycle.
  • the mixture was pressed on an eccentric press from Fette, "Exacta 31".
  • the pressing tools were coated with Vulkolan.
  • a filling height of 30.8 mm was required with a die diameter of 35 mm. This corresponded to a specific volume of 1.18 cm3 / g.
  • a depth of 14.5 mm was necessary to produce the tablet. This then corresponded to a tablet height of 16.3 mm or a specific volume of 0.62 cm3 / g.
  • the compression ratio was therefore 1: 1.9.
  • the actual tablet height after manufacture was 17.7 mm. This can be explained by the fact that the tablets can generally be expected to grow slightly after relaxation.
  • the pressing pressure required for pressing was 1,300 kp / cm2.
  • the tablets obtained had a flexural strength of greater than 15 kp and dissolved up to 14% by weight in the pre-rinse cycle and completely in the cleaning cycle.
  • the ingredients were mixed in a Lödige mixer.
  • the mixture was pressed on an eccentric press from Fette, type "Exacta”.
  • the pressing tools were coated with Vulkolan.
  • When pressed to a density of 1.56 g / cm3, tablets with a flexural strength (Ritschel, "Die Tablette, page 313) of 13.5 kp were obtained, which were added to tap water by approx. 20% by weight in the pre-rinse cycle of an HGSM. % and completely dissolve in the 40 ° C cleaning program.
  • Paraffin oil lubrication of the tools was not necessary.
  • the omission of calcium hydrogenphosphate dihydrate led to a dissolution of 25% by weight of the tablet in the pre-rinse cycle and to a 97% by weight total dissolution.
  • the residual moisture content caused the surface to show signs of weathering when the tablets were stored.
  • Example 4 The mixture composition, the tablet weight and the tablet diameter were chosen as in Example 4, but in contrast to Example 4, the density was 1.63 g / cm 3.
  • the bending ability here was greater than 15 kp.
  • 12% of the tablet was dissolved after the pre-rinse cycle. With excellent manufacturing and application properties, weathering of the tablet surface was also evident here during storage.
  • the weight was pressed on an eccentric press from Fette, type "Exacta 31", in which the pressing tools were coated with Vulkolan. When pressed to a density of 1.53 g / cm3, tablets with a flexural strength greater than 15 kp were obtained, which dissolved in the pre-rinse cycle to 14% by weight and in the cleaning program to 97% by weight.
  • the mixture was pressed on a rotary press from Fette, type "Perfecta 2" with plexiglass-coated tools.
  • the mixture was produced continuously on belt scales in a rack mixer, type "GAC 350".
  • the die was filled by a "Fil-o-Matic” from Fette. Caking of the material was avoided by paraffin oil lubrication (soaked felt rings on the lower punches). When compressed to a density of 1.52, tablets with a flexural strength greater than 15 kp were obtained.
