Definitions

  • the present invention relates to a dishwasher detergent.
  • the invention is therefore based on the object of developing a machine dishwashing detergent which has a lower pH than conventional dishwashing detergents and in particular has a pH below 10.5 (in a 1% strength aqueous solution), yet has good cleaning performance and consists of the environment is not composed or components that have as little pollution as possible.
  • a dishwasher detergent is known from EP-A 135 227, which is only weakly alkaline and has a pH of approximately 9.3-10.8 (in 0.3% aqueous solution), 25-50% by weight. Contains sodium triphosphate, 7.5-40% by weight sodium carbonate, 2-15% by weight sodium silicate, and a peroxy compound and enzyme. It is found that the effectiveness and stability of such a mildly alkaline, enzymatic composition is a matter of choosing the right amount of ingredients.
  • sodium metasilicate can be completely dispensed with in an effective dishwasher detergent if a mixture of sodium carbonate and sodium hydrogen carbonate is used instead.
  • This mixture offers the possibility to vary the pH value of the final formulation in a larger pH range, while maintaining the high alkalinity reserve.
  • this high reserve of alkalinity makes it possible to keep the enzyme content and builder content of the formulation very low. According to the invention, it is even possible to completely dispense with phosphate builders.
  • the machine dishwashing detergents according to the invention generally contain 20-80% by weight, preferably 30-70% by weight and in particular 45-55% by weight of sodium carbonate and 5-50% by weight, preferably 10-40% by weight and in particular 15-36% by weight sodium hydrogen carbonate.
  • US-P 4,306,987 discloses strongly alkaline dishwashing detergents with special low-foaming nonionic detergents.
  • These known dishwashing detergents generally contain 20-80% by weight of an alkaline detergent salt such as e.g. Sodium carbonate, sodium hydrogen carbonate and mixtures thereof, di- and trisodium orthopiosphate, sodium metasilicate, sodium sesquisilicate, borax and sodium borate, and as a bleaching agent 5 - 50% by weight chlorinated trisodium phosphate or instead a mixture of lithium hypochlorite or chlorinated cyanuric acid and trisodium phosphate.
  • the sodium silicate generally makes up 20-80%, preferably 20-40%.
  • the pH of the dishwasher detergents according to the invention is generally in the range from 9.0 to 10.5 or even less, preferably in the range from 9.9 to 10.4.
  • the ratio of sodium carbonate to sodium hydrogen carbonate is generally 4: 1 to 1: 1, preferably 3: 1 to 1: 1.
  • Preferred dishwashing detergents according to the invention with a pH of 9.0-10.5, preferably 9.9-10.4, contain 20-80% by weight sodium carbonate and 5-50% by weight sodium hydrogen carbonate, the combination of Sodium carbonate and sodium hydrogen carbonate make up at least 30 wt .-% of the total composition.
  • the dishwashing detergents according to the invention can contain a phosphate, conventionally sodium tripolyphosphate as a builder.
  • a suitable phosphate-containing dishwashing detergent contains 20-60% by weight sodium carbonate and 10-20% by weight sodium hydrogen carbonate, the sum of sodium carbonate and sodium hydrogen carbonate making up 30-70% by weight, and 10-40% by weight, preferably 20 - 35 wt .-% phosphate, especially sodium tripolyphosphate.
  • dishwasher detergents that are free of phosphates are particularly preferred.
  • phosphate-free builder systems can be used which replace the phosphate in whole or in part.
  • An acrylic acid / maleic acid copolymer for example the product Sokalan CP 5 ex BASF
  • a polyacrylic acid for example Acrysol LMW 45 ND ex Rhom & Haas
  • a phosphonic acid for example 1-hydroxyethane-1,1-diphosphonic acid / HEDP /
  • a phosphonic acid for example 1-hydroxyethane-1,1-diphosphonic acid / HEDP /
  • the polymer serving as a phosphate substitute can be used in an amount of 0 to 15% by weight, preferably 3 to 10% by weight.
  • the phosphonic acid is used in an amount of 0-10, preferably 2-4% by weight.
  • a phosphate-free builder system can also contain small amounts of low molecular weight polymers based on maleic acid or acrylic acid, e.g. Sokalan PM10 ex BASF or Sokalan PA15 ex BASF included.
  • the phosphate-free builder system can also contain nitrilotriacetic acid instead of phosphonic acids or low molecular weight polymers.
  • a suitable phosphate-free dishwasher detergent contains 25-60% by weight sodium carbonate and 10-35% by weight sodium hydrogen carbonate, the sum of sodium carbonate and sodium hydrogen carbonate making up 35-75% by weight, and 3-10% by weight of a phosphate-free polymeric builder.
  • the machine dishwashing detergents according to the invention are preferably free of silicates.
  • a small amount of disilicates or layered silicates can be advantageous as corrosion inhibitors. If such silicates are used as corrosion inhibitors, their amount should not exceed 15% by weight of the total composition, in general their proportion is 5-10% by weight.
  • the machine dishwashing detergents according to the invention preferably contain enzymes which, however, are already effective in very small amounts in the compositions according to the invention.
  • Proteases for example the product Savinase 4.0 T ex Novo
  • amylases for example the product Termamyl 60 T ex Novo
  • lipases can also be advantageous for certain types of soiling, especially at low washing temperatures.
  • the enzymes are generally used in amounts of 0-3% by weight, preferably 0.4-1% by weight.
  • Chlorine bleaches such as sodium dichloroisocyanurate
  • oxygen bleaches can advantageously be used, such as sodium perborate monohydrate, sodium perborate tetrahydrate, potassium monopersulfate, magnesium monoperoxyphthalate hexahydrate (H48), diperoxidodecanedioic acid (desensitized) and sodium percarbonate.
  • the machine dishwashing detergents according to the invention advantageously contain 3 to 15% by weight, preferably 3 to 10% by weight and in particular 5 to 8% by weight of sodium perborate monohydrate or sodium percarbonate.
  • a bleach activator such as e.g. TAED (tetraacetylethylenediamine), TAGU (tetraacetylglycoluril), GPA (glucose pentaacetate) and others be incorporated into the wording.
  • TAED tetraacetylethylenediamine
  • TAGU tetraacetylglycoluril
  • GPA glucose pentaacetate
  • compositions according to the invention can contain small amounts of a surfactant, preferably a nonionic surfactant, advantageously in an amount of up to 5% by weight, preferably up to 3% by weight and in particular up to 1% by weight. In general, amounts in the range of 0.2-2% by weight of a nonionic surfactant are completely sufficient.
  • the surfactants used must be low-foaming, so non-ionic surfactants are the most suitable. Low-foaming nonionic surfactants with good biodegradability are preferably used. This is e.g. adducts of ethylene oxide and propylene oxide or ethylene oxide and higher alkylene oxides with native or synthetic fatty alcohols or oxo alcohols. Corresponding adducts which are end group-closed are also very suitable.
  • the machine dishwashing detergent according to the invention may also contain other conventional ingredients, such as dyes, perfume oils or other auxiliaries, such as e.g. Stabilizers for enzymes.
  • the fatty acids or hydrocarbons are used in amounts of 0-3% by weight, preferably 0.5-2% by weight and in particular 0.7-1.5% by weight, based on the overall composition.
  • Sodium sulfate has also proven to be suitable as an anticaking agent and can be used instead of the white oils. Sodium sulfate is also suitable as a diluent. If the alkalinity of the formulation is to be reduced, part of the amount of sodium carbonate / sodium hydrogen carbonate can be replaced by sodium sulfate, but the minimum content of 25% by weight, preferably 30% by weight, of the sodium carbonate / sodium hydrogen carbonate combination must be maintained .
  • the machine dishwashing detergents according to the invention can therefore contain 0-35% by weight sodium sulfate.
  • a suitable, phosphate-containing composition according to the invention consists of 20-35% by weight sodium tripolyphosphate 35-55% by weight sodium carbonate 10 - 20% by weight sodium hydrogen carbonate 5-8% by weight sodium perborate monohydrate 0.4-1 wt% protease 0.4-1 wt% amylase 0.2-2% by weight of nonionic surfactant part of the sodium carbonate / sodium hydrogen carbonate amount by 0-20% by weight sodium sulfate can be replaced; and has a pH (in 1% solution) of 10.2 - 10.4.
  • a particularly suitable, phosphate-free composition according to the invention consists of 35-55% by weight sodium carbonate 20-35% by weight sodium hydrogen carbonate 5-8% by weight sodium perborate monohydrate 0.4-1 wt% protease 0.4-1 wt% amylase 0.2-2% by weight of nonionic surfactant 3 - 10% by weight acrylic acid / maleic acid / copolymer 0 - 4 wt .-% phosphonic acid , a part of the sodium carbonate / sodium bicarbonate amount can be replaced by 0-35% by weight sodium sulfate, and has a pH (in 1% solution) of 10.2-10.4.
  • the cleaning performance of the dishwasher detergents according to the invention is comparable to conventional, strongly alkaline dishwasher detergents based on sodium metasilicate.
  • the formulations according to the invention are even superior.
  • compositions according to the invention are much lower than those of comparable known formulations.
