Definitions

• the present invention relates to alkaline machine cleaners for cleaning kitchen appliances which comprise a special combination of phosphate substitutes, their use for kitchen appliances, in particular in the commercial kitchen sector, and the use of a special combination of phosphate substitutes in an alkaline machine cleaner.
• cleaning agents can have components based on phosphate and / or phosphonate, as well as phosphate and / or phosphonate-free constituents, as can be seen from the documents US 2003 064 911 A1 , WO 0109275 A1 , WO 2013 185 074 A2 , GB 2462173 A and EP 046 0797 A1 known.
• a machine cleaner according to the invention is a cleaning agent or a cleaning agent system for cleaning kitchen appliances, such as. B. commercial dishwashers, ovens, grill automats, convection ovens, large cooking containers, degreasing systems, as well as dirty surfaces from the commercial kitchen area.
• alkaline to highly alkaline cleaners are generally used, which mostly have a special cleaning power compared to, for example, conventional dishwasher tablets for use in the dishwasher for cleaning soiled dishes.
• complexing agents are all known as phosphate substitutes, but their special complexing effect, in particular with regard to the magnesium and calcium binding capacity, was not known to the person skilled in the art when used together. It was therefore surprising that it was possible to show in experiments that, in particular with a combination of the complexing agents methylglycine diacetic acid, polyepoxysuccinic acid and Na gluconate or polyaspartic acid, polyepoxysuccinic acid and Na gluconate, a higher calcium binding capacity can be achieved than with each individual complexing agent in the same concentration can be achieved.
• the cleaner comprises an alkali system made up of one or more components selected from sodium hydroxide (NaOH), caustic soda (highly concentrated NaOH) and metasilicate. These components give the cleaner a high alkalinity.
• An alkaline cleaner in the context of the invention is a powder or a tablet with an alkali system, which the powder or the tablet when dissolved in water, that is in a 1% aqueous solution, preferably an alkaline pH, more preferably a pH -Value greater than 10, particularly preferably greater than 12.
• an alkaline pH more preferably a pH -Value greater than 10
• One or a combination of several of these alkaline components or in combination with additional alkaline agents can be used in the alkaline cleaning tablet in order to appropriately adjust the alkalinity (also called "basicity").
• alkaline-based cleaning agents To dissolve fats and proteins from soiled surfaces, setting the pH to the above-mentioned preferred alkaline value is often sufficient, with alkaline-based cleaning agents also having a cleaning effect based on complex-forming groups or surface-active groups as long as they are effective can develop in an alkaline environment (pH value greater than 10).
• the cleaner according to the invention preferably contains the alkaline components of the alkali system in a total amount of about 20 to 70% by weight, particularly preferably in a proportion of about 40 to 60% by weight, based on the total cleaner, i.e. machine cleaner.
• These highly alkaline components are preferably admixed with a powder or a tablet matrix, the invention also falling within the scope of the invention if they are wholly or partially converted in the tablet matrix during tableting into more stable products, e.g. hydrates or oxides, etc., as long as this conversion occurs during use the cleaning tablet is reversible again in water, so that the desired alkalinity (also called “basicity” ) is provided.
• the tablet matrix can also be built up from the alkaline component itself. Adjustment of the pH value is often sufficient for the solution of fats and proteins from soiled surfaces, whereby cleaning agents on an alkaline basis can also have a cleaning effect based on complex-forming groups or surface-active groups. Protein-denaturing alkaline substances can also be used as cleaning components, as long as they can develop their effect in an alkaline environment.
• prepared cleaning solutions can be provided in which the alkali system and the complexing component are present in dissolved form. These cleaning solutions can be used immediately, as they do not require the components contained to dissolve.
• the solutions can, for example, be packaged in bottles with a suitable portioner or in water-soluble film containers, preferably in individual portions.
• the machine cleaner according to the invention can comprise further complexing agents, matrix components, builders and auxiliaries.
• the cleaner contains a complexing component with a combination of complexing agents or complexing auxiliaries in order to bind metals or metal ions, in particular calcium and magnesium, from hard water and from the food stains dissolved during the cleaning process.
• complexing agents in particular calcium and magnesium
• one or more of the following complexing agents can be used for this purpose in addition to
• the complexing components described above can be used as further complexing agents: Polymers and copolymers (e.g. polycarboxylates), sheet silicates, citric acid / citrates, etc.
• alkali-stable phosphate or phosphonate-containing additives for example phosphonates (e.g. salts of Nitrilotris-methylenephosphonic acid) of the Sequion types (manufacturer: Polygon) or Cublen types (manufacturer : Zschimmer & Schwarz) as additional complexing agents.
• the complexing component and further complexing agents are preferably used in a total amount of not more than 10 to 40% by weight, particularly preferably in a proportion of about 15 to 25% by weight, based on the total weight of the cleaner.
• surfactants In addition to the alkaline components and complexing agents, surface-active substances are used for cleaning. These substances, also known as surfactants, should expediently produce as little foam as possible in order to avoid excessive foam formation from the outset.
• Preferred surfactants are fatty alcohol ethoxylates, in particular end-capped Plurafac types (manufacturer: BASF), glucosides (manufacturer: Akzo) or fatty amines.
• Anionic surfactants are conceivable, but are less relevant because they are often very foaming.
• Surfactants are preferably used in an amount of about 0.2 to 20% by weight, particularly preferably in a proportion of about 0.5 to 5% by weight of the cleaner.
• the machine cleaner preferably contains a tablet matrix with customary matrix components.
• these can additionally include one or more builders (for example water-soluble sulfates such as Na sulfate) and / or auxiliaries, in particular for example binders, tabletting auxiliaries, disintegration accelerators, dissolution retarders, retardants or lubricants.
• builders for example water-soluble sulfates such as Na sulfate
• auxiliaries in particular for example binders, tabletting auxiliaries, disintegration accelerators, dissolution retarders, retardants or lubricants.
• the builders are preferably used in an amount of not more than 20% by weight, particularly preferably in a proportion of not more than 10% by weight of the cleaning tablet.
• the auxiliaries are preferably used in an amount of not more than 20% by weight, particularly preferably in a proportion of about 3 to 10% by weight of the cleaning tablet. The quantities given relate to the entire cleaning tablet.
• Binders or direct tabletting aids include starches, celluloses, polyethylene glycol, calcium compounds, bentonites, polysaccharides, sugar compounds, proteins or synthetic polymers.
• Exemplary disintegration accelerators include starches, (microcrystalline) celluloses, alginates, polysaccharides, proteins, cross-linked polyvinylpyrrolidine, polymethacrylate derivatives, or bentonites.
• Exemplary dissolution retarders or retarding agents include waxes, ethyl celluloses, fats, polyvinyl acetate, carboxymethyl cellulose, polyacrylic acid, polyethylene glycol, gels or stearates.
• lubricants examples include fatty acid esters, talc, oils and fats or fatty acids or pyrogenic silicic acid.
• a suitable combination of the various auxiliary substances or builders is used in accordance with the desired properties of the cleaning tablets, for example with regard to strength and solubility, and to ensure compressibility.
• An adhesive can preferably be used which strengthens the adhesion within the tablet matrix or between different tablet layers.
• polyethylene glycol can be incorporated into the tablet matrix as a powder for this purpose.
• a machine cleaner according to the invention can preferably be presented in the form of a powder or a tablet. If the machine cleaner is in the form of cleaning tablets, they can preferably be packed individually or in a defined number in a welded film, a so-called flowpack (a tubular bag in which the products are placed horizontally in the bag for packaging), so that they can be dosed precisely and easily on occasion.
• flowpack a tubular bag in which the products are placed horizontally in the bag for packaging
• the machine cleaner according to the invention described above is suitable for cleaning kitchen appliances, in particular from the commercial kitchen sector. This is why it can preferably be used for this.
