Definitions

  • the invention is directed to a detergent composition for dishwashers, the ingredients of which lead to an improved washing result. In particular, less “filming” is achieved while at the same time less “spotting” is achieved.
  • Machine dishwashing generally consists of a pre-wash cycle, one or more intermediate wash cycles, a final rinse cycle and a drying cycle. In principle, this applies to machine washing both in households and in the commercial sector.
  • the aim of machine washing is to achieve an optimal result without mechanical rubbing or wiping, as is the case with washing by hand.
  • the washing result should prevent the formation of a film (“filming”) or the remaining droplets ("spotting”) on the dishes.
  • a 3in1 tablet takes on the task of cleaning and rinsing and prevents the precipitation of Ca and Mg ions in the form of Salt.
  • the various functions are preferably released at different times during the flushing process.
  • the agents used for machine cleaning of dishes can be liquid, powder, paste or tablet form.
  • the use of tablets is particularly popular because of their ease of handling and dosing.
  • the object of the invention is to provide a detergent composition for use in machine dishwashers which brings about particularly good results in terms of "filming”, ie the formation of a film on the washed dishes, and at the same time the formation of droplet residues ("spotting") on the avoid washed dishes.
  • a detergent composition for machine dishwashers which (a) has at least one "carry over" surfactant, which has the general formula R 1 O (CH 2 CH 2 O) x (CH 2 CH 2 CH 2 O) y H, where R 1 is a linear or branched, saturated or unsaturated hydrocarbon radical having 6 to 30 carbon atoms, preferably 8 to 26, particularly preferably 10 to 24 carbon atoms, x is an integer between 26 and 200, y is an integer smaller is than 100 and x + y is less than 200 in amounts of 1 to 20% by weight, (b) a salt functional polymer is formed from monomers of acrylic acid and / or maleic acid in combination with at least one monomer which is selected / are from the group 2-acrylamido-2-methylpropanesulfonic acid, methallylsulfonic acid, or sulfonated styrene, it being possible for the salt functional polymer to be in acidic or neutral form.
  • R 1 is a linear or branched, saturated or unsatur
  • a “carry over” surfactant according to the present invention is to be understood as meaning a surfactant which, due to its structure and its properties, over the entire cleaning process up to the last rinse cycle in the Dishwasher "dragged". The details of this type of surfactant are discussed in greater detail below.
  • the detergent composition contains a salt function polymer that prevents the precipitation of Ca and Mg ions in the form of salts or prevents the crystal growth of precipitates that have already formed.
  • the detergent composition also includes a dispersant for non-water-soluble compounds / salts.
  • the detergent composition contains a salt function polymer that prevents the precipitation of Ca and Mg ions in the form of salts or prevents the crystal growth of precipitates that have already formed.
  • the detergent composition also includes a dispersant for non-water-soluble compounds / salts.
  • the detergent composition can be packaged in any commercially available form, e.g. liquid, paste, powder, granulate or particle form (e.g. spheres or so-called "pearls"), but is preferably used in the form of a pressed molded body.
  • the shaped body can be single-phase or multiphase.
  • a particularly preferred embodiment is a multiphase, pressed molded body, the individual phases in the washing liquor being able to be dissolved at different times.
  • Such a pressed molded body can contain a suitable disintegrant in individual (or in all) phases.
  • the mentioned ingredients carry over surfactant, salt function polymer and dispersant can be used in multiphase tablets in different phases or in different concentrations in the individual phases are present so that they are released into the washing liquor at different times (in different concentrations), but they can also be present in a uniformly distributed manner in all phases of multiphase tablets.
  • the formation of the film on the dishes is due, among other things, to the fact that the fatty acids from the triglycerides of the food residues in the dishwasher are saponified by the ingredients of the detergent composition.
  • Lime soaps as typical organic salts melt above certain temperatures. The melting temperature is determined by the chain length of the fatty acid. Below this melting temperature, however, they precipitate as insoluble soaps and settle on the dishes.
  • either the temperature profile of dishwashers can be varied in such a way that the washing water temperature does not fall below the failure limit of the lime soaps, or the calcium and magnesium ions in the washing liquor can be complexed as high as possible with the aid a salt or an agent with a salt function can be controlled.
  • Solid is understood to mean the formation of droplet residues, which can also be seen after the dishes have dried, especially on glasses. These remaining drops with dissolved salts leave stains on the dishes and glasses.
  • surfactants are used in conventional dishwashing detergents, which reduce the surface tension and thus allow the drops to run off the dishes better.
  • Suitable dispersants for the saponified fatty acids are all agents which are capable of dispersing non-water-soluble organic compounds such as lime soaps in an aqueous composition, especially at temperatures at which these compounds are present as insoluble compounds in the aqueous medium.
  • Such dispersants are known to the person skilled in the art, inter alia, from the areas of toilet cleaning articles, cutting oils, textile processing and the area of industrial cleaning. Common dispersants can easily be found on the Internet under the keyword "lime soap dispersant”. Examples of such dispersants are alkyl monopropionates, alkyl dipropionates, cocoamphocarboxyglycinates, alcohol ethoxycarboxylates, amine oxides, alkyldimethyl betaines, terephthalic acid, cocoamido propyl dimethyl betaines, alkylamino diacetates and citronella esters, as well as polymers based on acrylic acid, maleic acid and.

  • Carry over surfactants are those surfactants which, due to their hydrophilic-hydrophobic balance, are “carried over” through the individual cleaning and rinsing processes in a dishwasher during the course of the cleaning and rinsing process.
  • a statement that is not binding on the Invention is to be interpreted is that these surfactants due to their hydrophilic-hydrophobic properties are not subject to the usual Nernstian distribution (i.e. are not removed with the washing liquor and the rinsing water), but also increasingly adsorb on surfaces during the cleaning and rinsing process. This means that these surfactants are not only present in the washing liquor in the first wash or rinse cycle, but also in the last rinse cycles, albeit in a lower concentration there. This has the effect that the surface tension of the water is kept reduced even in the last wash cycles, which allows the water droplets to run off the items to be washed more easily.
  • Surfactants that fulfill this task are surfactants of the general formula R1O (CH2CH2O) x (CH2CH2CH2O) yH, where R1 is a linear or branched, saturated or unsaturated hydrocarbon radical with 6 to 30 carbon atoms, preferably 8 to 26, particularly preferably 10 to 24 Represents carbon atoms, x is an integer between 26 and 200, y is an integer less than 100 and x + y is less than 200. In a preferred embodiment, in at least one of the carry over surfactants used, x is greater than 30, and particularly preferably greater than 40, but less than 200. R1 is preferably a linear, saturated hydrocarbon radical.
  • Suitable surfactants are nonionic surfactants of the formula R2O [CH2CH (CH3) O] x [CH2CH2O] y [CH2CH (OH) R3], in which R2 stands for a linear or branched aliphatic hydrocarbon radical with 4 to 18 carbon atoms or mixtures thereof, R3 denotes a linear or branched hydrocarbon radical with 2 to 26 carbon atoms or mixtures thereof and x stands for values between 0.5 and 1.5 and y stands for a value of at least 15, preferably of at least 25.
