Description

The present invention relates to the removal of stains from food residues from textile or hard surfaces by the combination of bleaches with certain acylhydrazones.

Stains from food residues are one of the consumer-reluctant hard-to-remove stains; they often contain food additives such as thickening or stabilizing agents. Of these, polysaccharide-based hydrocolloids are often found which hydrate in cold or hot water and form viscous solutions, dispersions or gels. Useful polysaccharides may be of natural origin or made by modification thereof. The natural polysaccharides include algal extracts, plant extracts, hydrocolloids from seeds or roots, and hydrocolloids obtainable by microbial fermentation. Modified or semi-synthetic hydrocolloids include, for example, cellulose and starch derivatives and similar compounds such as methoxy-pectins, propylene glycol alginates and carboxymethyl and hydroxypropyl guar gum.

A commonly found food residue polysaccharide, guaran, is available from the seed walls of legume Cyamopsis tetragonoloba and has a 1-4-β-D-mannopyranosyl backbone. It is used as a thickener especially in ready-made sauces and frozen foods, but also in chocolate. The polysaccharide obtainable from locust bean fruits is also frequently used in the food industry; it also has a 1-4-β-D-mannopyranosyl backbone and is likely to differ from guaran by having a lower number of D-galactosyl side chains. In legume seeds, the generally water-soluble galactomannan accounts for the majority of stored carbohydrates, which in some cases can be up to 20% of the dry weight. Galactomannan has α-galactosyl residues attached to O-6 of mannose and may also be at least partially acetylated to O-2 and O-3 of the mannose residues.

These hydrocolloids have a very high affinity for cellulose and are difficult to remove even with modern bleaches. In the international patent applications WO 99/09130 respectively WO 00/09131 It has been proposed to use mannanase and percarbonate or mannanase and a hydrophobic bleach activator for this purpose.

From the international patent application WO 2009/124855 For example, metal complexes with acylhydrazone ligands bearing electron-withdrawing substituents near the acyl group are known.

With regard to component d), in a preferred embodiment, 15% by weight to 35% by weight of alkali metal phosphate, in particular trisodium polyphosphate, is contained. Alkaliphosphat is the summary term for the alkali metal (especially sodium and potassium) salts of the various phosphoric acids, in which one can distinguish metaphosphoric acids (HPO ₃ ) _n and orthophosphoric H ₃ PO _{4 in} addition to high molecular weight representatives. The phosphates combine several advantages: they act as alkali carriers, prevent lime deposits on machine parts or lime incrustations in fabrics and also contribute to the cleaning performance. Sodium dihydrogen phosphate, NaH ₂ PO ₄ , exists as a dihydrate (density 1.91 gcm ^-3 , melting point 60 °) and as a monohydrate (density 2.04 gcm ^-3 ). Both salts are white powders which are very soluble in water and which lose their water of crystallization when heated and at 200 ° C into the weak acid diphosphate (disodium hydrogen diphosphate, Na ₂ H ₂ P ₂ O ₇ ), at higher temperature in sodium trimetaphosphate (Na ₃ P ₃ O ₉ ) and pass on Madrell's salt. NaH ₂ PO _{4 is} acidic; It arises when phosphoric acid is adjusted to a pH of 4.5 with sodium hydroxide solution and the mash is sprayed. Potassium dihydrogen phosphate (potassium phosphate primary or monobasic potassium, potassium biphosphate, KDP), KH ₂ PO ₄ , is a white salt of density 2.33 gcm ^-3 , has a melting point of 253 ° (decomposition to form (KPO ₃ ) _x , potassium polyphosphate) and is slightly soluble in water. Disodium hydrogen phosphate (secondary sodium phosphate), Na ₂ HPO ₄ , is a colorless, very slightly water-soluble crystalline salt. It exists anhydrous and with 2 moles (density 2.066 gcm ^-3 , loss of water at 95 °), 7 moles (density 1.68 gcm ^-3 , melting point 48 ° with loss of 5 H ₂ O) and 12 moles water ( Density 1.52 gcm ^-3 , melting point 35 ° with loss of 5 H ₂ O) becomes anhydrous at 100 ° C and, upon increased heating, passes into the diphosphate Na ₄ P ₂ O ₇ . disodium is prepared by neutralization of phosphoric acid with soda solution using phenolphthalein as indicator. Dipotassium hydrogen phosphate (secondary or dibasic potassium phosphate), K ₂ HPO ₄ , is an amorphous, white salt that is readily soluble in water. Trisodium phosphate, tertiary sodium phosphate, Na ₃ PO ₄ , are colorless crystals which have a density of 1.62 gcm ^-3 as dodecahydrate and a melting point of 73-76 ° C (decomposition), as decahydrate (corresponding to 19-20% P ₂ O ₅ ) have a melting point of 100 ° C and in anhydrous form (corresponding to 39-40% P ₂ O ₅ ) have a density of 2.536 gcm ^-3 . Trisodium phosphate is readily soluble in water under alkaline reaction and is prepared by evaporating a solution of exactly 1 mole of disodium phosphate and 1 mole of NaOH. Tripotassium phosphate (tertiary or tribasic potassium phosphate), K ₃ PO ₄ , is a white, deliquescent, granular powder of density 2.56 gcm ^-3 , has a melting point of 1340 ° and is readily soluble in water with an alkaline reaction. It arises, for example, when heating Thomasschlacke with coal and potassium sulfate. Despite the higher price, the more soluble, therefore highly effective, potassium phosphates are often preferred over the corresponding sodium compounds in the detergent industry. Tetrasodium diphosphate (sodium pyrophosphate), Na ₄ P ₂ O ₇ , exists in anhydrous form (density 2.534 gcm ^-3 , melting point 988 °, also indicated 880 °) and as decahydrate (density 1.815-1.836 gcm ^-3 , melting point 94 ° with loss of water) , For substances are colorless, in water with alkaline reaction soluble crystals. Na ₄ P ₂ O ₇ is formed on heating of disodium phosphate to> 200 ° or by reacting phosphoric acid with soda in a stoichiometric ratio and dewatering the solution by spraying. The decahydrate complexes heavy metal salts and hardness agents and therefore reduces the hardness of the water. Potassium diphosphate (potassium pyrophosphate), K ₄ P ₂ O ₇ , exists in the form of the trihydrate and is a colorless, hygroscopic powder with a density of 2.33 gcm ^-3 , which is soluble in water, the pH being 1% Solution at 25 ° 10.4. Condensation of NaH ₂ PO ₄ or KH ₂ PO ₄ results in higher mol. Sodium and potassium phosphates, in which one can distinguish cyclic representatives, the sodium or Kaliummetaphosphate and chain types, the sodium or potassium polyphosphates. In particular, for the latter are a variety of names in use: melting or annealing phosphates, Graham's salt, Kurrolsches and Madrell's salt. All higher sodium and potassium phosphates are collectively referred to as condensed phosphates. The technically important pentasodium triphosphate, Na ₅ P ₃ O ₁₀ (sodium tripolyphosphate), is an anhydrous or with 6 H ₂ O crystallizing, non-hygroscopic, white, water-soluble salt of the general formula NaO- [P (O) (ONa) -O] _n -Na with n = 3. In 100 g of water dissolve at room temperature about 17 g, at 60 ° about 20 g, at 100 ° around 32 g of the salt water-free salt; after two hours of heating the solution to 100 ° caused by hydrolysis about 8% orthophosphate and 15% diphosphate. In the preparation of pentasodium triphosphate, phosphoric acid is reacted with sodium carbonate solution or sodium hydroxide solution in a stoichiometric ratio and the solution is dehydrated by spraying. Similar to Graham's salt and sodium diphosphate, pentasodium triphosphate dissolves many insoluble metal compounds (including lime soaps, etc.). Pentapotassium triphosphate, K ₅ P ₃ O ₁₀ (potassium tripolyphosphate), comes for example in the form of a 50 wt .-% solution (> 23% P ₂ O ₅ , 25% K ₂ O) in the trade. The potassium polyphosphates are widely used in the washing and cleaning industry. There are also sodium potassium tripolyphosphates which can also be used in the context of the present invention. These arise, for example, when hydrolyzed sodium trimetaphosphate with KOH:

(NaPO ₃ ) ₃ + 2 KOH → Na ₃ K ₂ P ₃ O ₁₀ + H ₂ O

These are just like sodium tripolyphosphate, potassium tripolyphosphate or mixtures of these two applicable; It is also possible to use mixtures of sodium tripolyphosphate and sodium potassium tripolyphosphate or mixtures of potassium tripolyphosphate and sodium potassium tripolyphosphate or mixtures of sodium tripolyphosphate and potassium tripolyphosphate and sodium potassium tripolyphosphate.

Mixtures of the aforementioned optical brightener can be used.

In particular when used in automatic washing or cleaning processes, it may be advantageous to add conventional foam inhibitors to the compositions. As foam inhibitors are, for example, soaps of natural or synthetic origin, which have a high proportion of C ₁₈ -C ₂₄ fatty acids. Suitable non-surfactant foam inhibitors are, for example, organopolysiloxanes and mixtures thereof with microfine, optionally silanized silica and paraffins, waxes, microcrystalline waxes and mixtures thereof with silanated silicic acid or bis-fatty acid alkylenediamides. It is also advantageous to use mixtures of various foam inhibitors, for example those of silicones, paraffins or waxes.

In the case of their use as granules, if desired, these may also contain further active substances, in particular bleach activator.

The preparation of solid agents presents no difficulties and may be carried out in a manner known in the art, for example by spray drying or granulation, with peroxygen compound and bleach activator combination optionally being added later. In order to produce the compositions having an increased bulk density, in particular in the range from 650 g / l to 950 g / l, a process comprising an extrusion step is preferred. Detergents, cleaners or disinfectants in the form of aqueous or other conventional solvent-containing solutions are particularly advantageously prepared by simply mixing the ingredients, which can be added in bulk or as a solution in an automatic mixer. In a preferred embodiment of means for the particular machine cleaning of dishes, these are tablet-shaped.
