Definitions
- the invention relates to a means for the simultaneous machine cleaning and rinsing of dishes and a method for the simultaneous cleaning and rinsing of dishes in dishwashers.
- the cleaner has the task of swelling the food residues during the cleaning cycle of the dishwasher, detaching them from the dishes and dispersing them in the detergent fleet.
- the dishes are washed with the addition of rinse aid. Due to its composition, the rinse aid has the task, on the one hand, of relaxing the water, so that the water forms a closed, increasingly thinner film on the surface of the dishes, which then peels off, and, on the other hand, of ensuring that the dishes are uniform after drying Has gloss.
- a machine-applicable powder dishwashing detergent with a content of condensed phosphates, silicates, alkalis, nonionic surfactants, active chlorine-releasing compounds and water-soluble organic polymers which is characterized in that it is - based on the total weight of the above-mentioned constituents, including any adhesives present Water or water of hydration - as nonionic surfactant 0.5-5, preferably 0.8-2 percent by weight of an ethoxylated and then propoxylated fatty alcohol and as water-soluble organic polymers 0.2-2.5, preferably 0.8-1.2 percent by weight of polyethylene glycols an average molecular weight between 300,000 and 4,000,000, preferably between 500,000 and 1,000,000.
- Machine-applicable powder dishwashing detergents containing condensed phosphates, silicates, alkalis, ethoxylated and propoxylated fatty alcohols, active chlorine-releasing compounds and water-soluble organic polymers are already known from DE-A 25 01 529.
- a corresponding teaching can also be found in DE-A 24 35 479. This does not make the use of rinse aid after the automatic cleaning cycle of the dishwasher unnecessary.
- nonionic surfactants mentioned are known in a known manner by reacting about one mole of a mixture of C 12 -C 18 , preferably C, 2-C1, fatty alcohols with 1, preferably 1-3, moles of ethylene oxide and then 2-7, preferably 4 -6 moles of propylene oxide produced.
- the polyethylene glycols are prepared in a known manner, namely, for example, by subjecting ethylene glycols to a polycondensation process. They can also be considered as condensation polymers of ethylene oxide with ethylene glycol or water. They have the general formula HO (-CH2-CH2-O) nH, where n can vary between 4,800 and 64,000 in the case of the polyethylene glycols used according to the invention. Such polymers are also commercially available and are sold by Union Carbon Carbide Corporation (UCC) under the registered trademark "POL YOX @".
- Condensed phosphates suitable for the purposes of the invention are the water-soluble alkali metal salts of di- or triphosphoric acid or the water-soluble alkali metal hexametaphosphates which are usually used as complexing agents in dishwashing detergents.
- Sodium or potassium metasilicates are used as alkali metal silicates, in which the ratio of alkali oxide to silicon dioxide is 1: 0.9 to 1: 1.5. These compounds are preferably anhydrous. However, they can contain 4.70 to 5 moles of water of crystallization.
- Suitable alkali metal hydroxides or alkali metal carbonates are primarily sodium or potassium hydroxide or the corresponding carbonates.
- water-soluble alkali silicates are those in which the ratio of alkali oxide to silicon dioxide is approximately 1: 1.5 to 3.8 and which are generally known as sodium or potassium water glass.
- Trichloroisocyanuric acid or its alkali metal salts e.g. B. potassium and sodium dichloroisocyanurate or their dihydrates or mixtures thereof.
- alkali and alkaline earth hypochlorites such as lithium, sodium or calcium hypochlorite as well as complex salts containing hypochlorites, e.g. so-called chlorinated phosphates, trichloromelamine, chloramine T and other active chlorine-releasing compounds.
- the amounts stated in the description of the invention relate to salts free of hydrated water.
- the claimed mixtures may optionally contain smaller amounts of further components, in particular inorganic salts such as sodium sulfate or sodium chloride.
- inorganic salts such as sodium sulfate or sodium chloride.
- Other possible additives are substances with a buffering action, such as sodium acetate, dyes, perfumes, and corrosion inhibitors, such as sodium and calcium compounds, e.g. B. NaOH and Ca (OH) 2 ' zeolites. This would inevitably reduce the proportion of the building blocks of the funds accordingly if all the components were to be 100 percent by weight.
- the claimed powdery compositions can be packaged in a known manner by grinding and mixing the constituents. In order to achieve an intimate connection of the powder constituents, it may be appropriate to mix the powder with an aqueous solution of crystallizing salts, e.g. B. sodium sulfate or one of the nonionic surfactants mentioned. This treatment also reduces the tendency of the powder to dust.
- crystallizing salts e.g. B. sodium sulfate or one of the nonionic surfactants mentioned. This treatment also reduces the tendency of the powder to dust.
- the claimed detergent combinations are characterized by a high cleaning ability. They are particularly suitable for removing burnt-on, protein-containing food residues, lipstick marks and tea stains. They are able to prevent the formation of starch deposits on the tableware surfaces or to remove existing coverings again. Particularly noteworthy is the low corrosion effect of the claimed mixtures, particularly in the case of porcelain overglaze decorations.
- the claimed agents can be used both in household dishwashers and in commercial dishwashers. It is added by hand or using suitable dosing devices.
- the application concentrations in the cleaning liquor are about 0.5-10, preferably 2-5 g / l.
- the pH values of the cleaning liquors are between pH 7-13, preferably pH 8-12.
- the advantage of the claimed agents is that no rinse aid needs to be added in the last rinse, but only rinsed with pure tap water and still a rinse aid result is achieved that is at least as good or even better than that of the conventional method using the two-way combination of a detergent and a rinse aid. This simplifies the handling of the dishwasher, because after the cleaning cycle using the new dishwashing detergent alone, it is sufficient for a perfect washing result to rinse the dishes with clear water and then dry them as usual. After drying you get a completely clean and hygienically perfect dishes.
- the present invention therefore also relates to a method for the simultaneous machine cleaning and rinsing of dishes, which is characterized by the use and the one-time and sole addition of the claimed agents in the cleaning cycle of a dishwasher.
- a point system of 0-10 was also used for the evaluation of the clear dry effect on the glasses, whereby 0 points mean «completely inadequate clear drying (stripes, stains, etc.) and 10 points « perfect clear drying (high-gloss glasses without streaks and stains).
- the mean values of the cleaning and clear dryer results were determined for each mixture from double experiments. For comparison, the mean values of the cleaning and clear drying effects of a commercial rinse aid and an inventive detergent combination using a commercial rinse aid were also determined.
- the commercial cleaner had the following composition: 36% sodium tripolyphosphate, 39% sodium metasilicate, 6% sodium carbonate, 2% sodium dichloroisocyanurate, 1% nonionic surfactant and 16% water. It was used at a concentration of 3 g / 1 liquor.
- the commercial rinse aid was composed of 15% of a nonionic surfactant and 20% citric acid in aqueous alcoholic solution and was used in a concentration of 0.3 g / l of liquor.
