Definitions
- Machine dishwashing generally consists of a pre-wash cycle a cleaning cycle, one or more intermediate rinse cycles, a rinse cycle and a drying cycle. In principle, this applies to the machine Rinsing both in households and in the commercial sector.
- the means used for the automatic cleaning of dishes can be liquid, pasty, powdery and tablet-like.
- the application in Tablet form is becoming increasingly popular due to its easy handling.
- a number of manufacturing processes have already been described that lead to tablets with time-controlled dissolution behavior. These tablets are often in the machine room itself and no longer in the boxes in the door room intended for detergent dosing positioned, which allows some of the tablets to already be is dissolved in the pre-rinse cycle and so the effect of the usually additive-free Tap water is chemically supported in this phase.
- DE 35 41 145 uniformly composed alkaline Detergent tablets known for machine dishwashing, which have a broad solubility profile and a mixture of Sodium metasilicate nonahydrate and anhydrous metasilicate as well as anhydrous Pentasodium triphosphate and possibly other ingredients contain.
- DE 41 21 307 describes stable, bifunctional, phosphate and metasilicate - free alkaline detergent tablets for the machine dishwashing known, the framework components partially used in anhydrous form and in the manufacture with water were sprayed what the desired solubility profile and good compressibility caused.
- Detergent tablets come when you manufacture them on the Add free water and the use of slightly hydrated water Connections omitted and the powdery or crystalline components of the detergent mixture individually and / or as mutually compatible powdered or optionally granulated partial mixtures hydrophobized, optionally mixed again, further hydrophobized or also adds non-hydrophobic components and the resulting ones the resulting mixture is compressed into tablets.
- the detergent tablets of the present invention can be strong alkaline with pH values> 11, but also low alkaline with pH values below Be 11. So you can in a known manner Pentaalkalitriphosphate, alkali silicates, Alkali carbonates, bleaches, optionally activators for these as well as alkali hydroxides, zeolites and / or enzymes, wherein again individual constituents or mixtures thereof can be made hydrophobic. But they can also be low alkaline, phosphate and silicate free and oxygen-releasing compounds instead of active chlorine-releasing compounds as bleaching agents Connections and activators for these connections as well as contain enzymes. In both cases, they can also be low-foaming contain non-ionic surfactants.
- the present invention preferably relates to fracture-stable and lab-stable, phosphate and preferably alkali silicate free, low alkaline polyfunctional Detergent tablets, especially for machine washing of dishes based on framework substances, non-ionic surfactants, Enzymes, bleaches and activators for this, which are characterized are that the powdery or crystalline constituents individually or as mutually compatible powdered or optionally granulated Mixtures with the same or different hydrophobizing compounds are coated, the hydrophobizing compounds as such still contain liquid or powdered tablet components can.
- the hydrophobizing compounds become liquid or liquefied Form via a nozzle which can be regulated in a known manner onto the powdery or crystalline components or mixtures thereof, wherein a thin protective coating forms on the solid fabrics, which the more uniform and stable the more finely divided the liquid particles present after exiting the nozzle.
- the water repellent Substance is in liquid form during the hydrophobization process. He can a liquid under normal conditions, e.g. be an oil or it can be also a solid, e.g. Be wax, which in the molten state is processed in the hydrophobic stage.
- Trisodium citrate dihydrate can be used as a fine or coarse crystalline powder.
- the content of trisodium citrate dihydrate is about 20 to 80, preferably about 30 to 60% by weight; it can be wholly or partially, i.e. up to about 80, preferably about 50 wt .-% of its weight by occurring in nature Hydroxycarboxylic acids such as e.g. Mono-, dihydroxysuccinic acid, ⁇ -hydroxypropionic acid and gluconic acid are replaced.
- the tablets according to the invention may also contain alkali carbonates, alkali hydrogen carbonates, alkali sulfates or polycarboxylates as further framework and / or filling substances.
- alkali carbonates such as Sokalan (R) CP 5 (BASF) or completely biodegradable polymers, such as oxidized starches or dextrin, can also serve as additional tabletting aids.
- the amount of alkali metal carbonates which can preferably be used in compact form is then about 0 to about 15, preferably about 2 to 12% by weight. If naturally occurring Na 2 CO 3 xNaHCO 3 (Trona / Solvay) is used, the amount used may have to be doubled.

- defoaming agents such
- Enzymes such as proteases, amylases, lipases and cellulases, for example proteases such as BLAP (R) 140 from the Henkel company, are used for better detachment of food residues containing protein, starch or, for example, tallow fat.
- the amounts of the enzymes usually used as a mixture in the total average are each about 0.5 to 5, preferably about 1 to 4 wt .-%.
- Active oxygen carriers are currently preferably used as bleaching agents. These include primarily sodium perborate mono- and tetrahydrate and sodium percarbonate. But also the use of, for example Boron compounds stabilized sodium percarbonate (German Offenlegungsschrift 33 21 082) has advantages, since this is particularly favorable on the Corrosion behavior affects glasses. Because active oxygen is only at elevated Temperatures unfold their full effect by themselves its activation at approx. 60 ° C, the approximate temperatures of the cleaning process used in the HGSM, so-called bleach activators.
- Bleach activators are preferably used for TAED (tetraacetylethylene diamine), PAG (Pentaacetylglucose), DADHT (1,5-diacetyl-2,2-dioxo-hexahydro-1,3,5-triazine) and ISA (isatoic anhydride).
- the addition can be lower Amounts of known bleach stabilizers, such as alkali phosphonates, Alkali borates or alkali metaborates and metasilicates be useful.
- the proportion of bleaching agent in the total is about 1 to 20, preferably about 2 to 12 wt .-%, that of the bleach activator about 1 to 8, preferably about 2 to 4% by weight.
- Paraffin oils and solid paraffins are used as hydrophobizing agents Melting ranges from 30 to 60 ° C, preferably 35 and 45 ° C into consideration. Paraffins with melting ranges of 42-44 ° C are preferred.
- Corrosion inhibitors for precious metals for example inorganic or organic redox-active substances. These include metal salts and / or metal complexes from the group consisting of manganese, titanium, zirconium, hafnium, vanadium, cobalt and cerium salts and / or complexes, the metals being in one of the oxidation states II, III, IV, V or VI are present (PCT 94/01386), and ascorbic acid, N-mono- (C 1 -C 4 -alkyl) -glycine or N, N-di- (C1-C4-alkyl) -glycine, couplers and / or developing agents such as diaminopyridines, aminohydroxypyridines, dihydroxypyridines, heterocyclic hydrazones, tetraaminopyrimidines, Triaminohydroxypyriminide, Diaminodihydropyromidine, Dihydroxyhaphtaline, naphthols,
