Definitions
- the invention relates to a mildly alkaline Dishwasher detergent containing a bleach Oxygen base and other common ingredients.
- the invention therefore relates to mildly alkaline Dishwasher detergents, which are generally used Concentration of the rinse liquor effect under 11.
- the pH of the Wash liquor of such mildly alkaline machine dishwashing detergents 9-11, preferably 9.5-10.8.
- the invention teaches one such mildly alkaline dishwasher detergent additives which must ensure that at the end of the cleaning cycle in the alkaline environment the bleach content of the washing liquor in the is substantially completely dismantled. Under essentially completely degraded one understands an oxygen content that is completely or almost completely degraded.
- An encapsulated for example, is suitable as an additive enzyme suitable for oxygen degradation, for example Peroxidase, e.g. Catalase.
- an additive enzyme suitable for oxygen degradation for example Peroxidase, e.g. Catalase.
- the additive can be an encapsulated reducing agent, for example, thiosulfate.
- An encapsulated one is also suitable as an additive Heavy metal or its compound, such as Copper, iron, manganese, zinc or titanium, which is capable is to catalytically decompose the bleach.
- TAED tetraacetylethylenediamine
- TAGU Tetraacetylglycoluril
- GPA gluccsepenta acetate
- NOBS Sodium nonaoylbenzenesulfonate
- PAG penentaacetyl glucose
- DADHT diacetyldioxohexahydrotriazine
- ISA Isatoic anhydride
- TAED is a modern detergent additive, which by Implementation with hydrogen peroxide leads to peracids. It put two molecules of hydrogen peroxide with one Molecule around TAED. For all recipes, therefore, is after Manufacturer's instructions to pay attention to. that at least 2 moles Perborate can be used on 1 mole of TAED. In practice a much higher excess of perborate is used (see TAED brochure from Hoechst).
- the oxygen activator is now preferably opposed to the previous application recommendations in a stoichiometric excess used against the bleach.
- Sodium perborate Sodium percarbonate and / or Potassium monopersulfate or known stabilized qualities of these substances.
- Sodium perborate monohydrate is particularly preferred.
- the stoichiometric ratio of TAED to bleach like for example sodium perborate is 0.5: 1.
- the oxygen activator in a molar ratio to Bleaching agents of over 0.5: 1, preferably at least 0.65: 1.
- a machine dishwashing detergent is particularly preferred which the activator TAED and the bleaching agent sodium perborate monohydrate is, with the activator in one Weight ratio to bleach of at least 1.14: 1, preferably of at least 1.5: 1.
- a combination of one or several activators and encapsulated additives which, in combination with the activator, reduce the oxygen content effect at the end of the cleaning cycle.
- the table below shows that with a TAED / sodium perborate monohydrate ratio of 1.5, as is preferred according to the invention, a high amount of active oxygen is used and nevertheless only a very small amount of active oxygen is carried over into the first intermediate rinse cycle .
- the active oxygen content used is therefore just as high as with a TAED / perborate ratio of 0.27, but the residual oxygen content at the end of the cleaning cycle and the oxygen content carried over into the first intermediate rinse cycle are only very low.
- the mildly alkaline machine dishwashing detergents according to the invention also contain other customary constituents. These include sodium carbonate, sodium or potassium silicates such as sodium disilicate, phosphates such as sodium tripolyphosphate, builders and buffering substances such as trisodium citrate, as well as surfactants, especially nonionic surfactants, in a total amount of up to 5, preferably up to 2% by weight. can be present.
- the dishwashing detergents according to the invention preferably also contain the enzymes customary in such detergents, such as amylase and / or protease.
- a household dishwasher was loaded with dishes and silver cutlery, which had the following contamination: 50 ml of a mixture of Ketchup 25 g mustard 25 g gravy 25 g Potato starch 5 g Benzoic acid 1 g egg yolk 3rd milk 500 g water 700 g 20 program sequences; Water hardness 18-20 ° d
