Definitions
- active oxygen compounds such as sodium perborate or sodium percarbonate, which are used to remove bleachable soiling, for example Tea stains / tea deposits, coffee residues, vegetable dyes, lipstick residues and the like are used.
- active oxygen compounds are mainly used in modern low-alkaline machine dishwashing detergents of the new generation of detergents together with bleach activators.
- These modern agents generally consist of the following functional components: builder component (complexing agent / dispersant), alkali carrier, bleaching system (bleach + bleach activator), enzymes and wetting agents (surfactants).
- the silver surfaces are generally more sensitive to the changed recipe parameters of the new generation of active chlorine-free cleaners with lowered pH values and activated oxygen bleaching. During machine rinsing, these agents release the actual bleaching agent hydrogen peroxide or active oxygen in the cleaning cycle.
- the bleaching effect of the active oxygen-containing cleaners is enhanced by bleach activators, so that a good bleaching effect is achieved even at low temperatures. In the presence of these bleach activators, peracetic acid forms as a reactive intermediate.
- peracetic acid forms as a reactive intermediate.
- silver in the presence of silver not only oxidic deposits, but preferably oxidic deposits on the silver surfaces due to the oxidizing attack of the intermediately formed peroxides or the active oxygen substance are formed. If the salt load is high, chloridic deposits can additionally develop.
- the tarnishing of the silver is also reinforced by higher residual water hardness during the cleaning cycle.
- alkaline dishwashing detergents which contain benzotriazoles as a corrosion inhibitor for silver.
- machine-applicable dishwashing detergents which can contain, among other things, perborate with an organic bleach activator as the oxidizing agent.
- Additions of benzotriazole and iron (III) chloride, among others, are recommended as anti-tarnish agents.
- PH values of preferably 7-11.5 are mentioned.
- EP 135 226 and EP 135 227 describe weakly alkaline, machine-usable dishwashing detergents containing peroxy compounds and activators, which may contain, among other things, benzotriazoles and fatty acids as silver preservatives.
- peroxy compounds and activators which may contain, among other things, benzotriazoles and fatty acids as silver preservatives.
- German Offenlegungsschrift DE 41 28 672 that peroxy compounds which are activated by addition of known organic bleach activators prevent silver parts from tarnishing in strongly alkaline cleaning agents.
- organic redox-active substances in particular the coupler and / or developer compounds which are usually used in oxidation colorants and have not hitherto been described as silver corrosion inhibitors, effectively prevent the corrosion of silver in machine dishwashers.
- the invention relates to the use of organic redox-active substances in dishwashing detergent preparations as silver corrosion protection agents.
- corrosion is to be interpreted in its broadest use in chemistry. In particular, “corrosion” should stand for every visually just recognizable change in a metal surface, here silver. B. a selective discoloration, be it z. B. a large area tarnishing.
- Organic redox-active substances are those organic substances which are accessible to easily reversible oxidation and / or reduction. For example, typical complexing agents such. B. EDTA or hydroxyethane diphosphonic acid and related compounds do not fall under this definition.
- organic redox-active substances z. As ascorbic acid (vitamin C), indole, methionine ( ⁇ -amino-7-methyl-ercaptobutyric acid).
- N-mono- (C 1 -C 4 -alkyl) glycines e.g. N-mono-methyl-glycine and N, N-di- (-C-C4-alkyl) -glycine, e.g. N, N-dimethylglycine and 2-phenylglycine.
- Coupler and / or developer compounds known from oxidative dyeing are also particularly suitable.
- the preferably used organic substances to prevent the corrosion of silver are coupler and / or developer compound chosen from the group of diaminopyridines, aminohydroxypyridines, Dihydroxypyri- dine, heterocycli Service hydrazones, aminohydroxypyrimidines, Dihydroxypyri i- dine, tetraaminopyrimidines, triaminohydroxypyrimidines, Diaminodihydroxy- pyrimidines Dihydroxynaphtaline, naphthols , Pyrazolones, hydroxyquinolines, aminoquinolines, the primary aromatic amines, which have a further free or substituted with C 1 -C 4 -alkyl or C2-C4 ⁇ hydroxyalkyl groups in the ortho, meta or para position, and the di or trihydroxybenzenes.
- the developer and coupler compounds used according to the invention to prevent silver corrosion are the substances from the abovementioned groups that are usually used in oxidation dyeing agents. Examples of such developer and coupler compounds can be found, for example, in "Venkataraman, The Che istry of synthetic dyes, Vol. V, Academic Press New York / London, 1971, pages 478-495", and in the literature cited there.

- the melting point should therefore ideally be in the range between 45 ° C and 65 ° C and preferably in the range 50 ° C to 60 ° C for most applications.
- the organic redox-active substances described above are particularly suitable for preventing silver corrosion if they are contained in alkaline cleaners for the automatic cleaning of dishes. This is all the more surprising since the effectiveness of these silver corrosion protection agents is not impaired by the presence of oxygen-based bleaching agents usually present in lower-alkaline cleaners.

- the production of machine dishwashing detergents in the form of non-dusting, storage-stable, free-flowing powders and / or granules with high bulk densities in the range from 750 to 1000 g / l is characterized in that in a first process stage, the builder components are at least partially liquid Mixing components mixed with increasing the bulk density of this premix and subsequently - if desired after an intermediate drying - the further components of the dishwasher detergent, including organic redox-active substances, combined with the premix obtained in this way.
- the intermediate drying must be carried out so that the decomposition of the sodium bicarbonate to sodium carbonate is as low as possible (or at least as constant as possible).
- An additional sodium carbonate portion resulting from the drying would have to be in the formulation of Granulate recipe are taken into account.
- Low drying temperatures not only counteract sodium bicarbonate decay, but also increase the solubility of the granulated detergent during use. It is therefore advantageous for drying to have a supply air temperature which, on the one hand, should be as low as possible to avoid bicarbonate decomposition and, on the other hand, must be as high as necessary in order to obtain a product with good storage properties.
- a supply air temperature of approximately 80 ° C. is preferred during drying.
- the builder is generally charged with the liquid components in admixture with at least one further component of the dishwashing detergent.
- a precursor may be considered in which the builder component, mixed with perborate, is acted upon by the liquid nonionic surfactants and / or the solution of the fragrances and mixed intimately.
- the remaining components are then added and the entire mixture is worked through and homogenized in the mixing device.
- additional amounts of liquid in particular the use of additional water, is generally not necessary here.
- the mixture of substances obtained is then in the form of a free-flowing, dust-free powder of the desired high bulk density in the range from 750 to 1000 g / l.
- the pre-granules are then mixed with the still missing components of the dishwashing detergent, including organic redox-active substances, to form the finished product.
- the mixing time is both in the preliminary stage of the compacting mixture under the influence of liquid components and in the subsequent final mixture with the other components in the range of a few minutes, for example in the range of 1 to 5 minutes.
- the agents to be used can be used both in household dishwashers and in commercial dishwashers. They are added by hand or using suitable dosing devices.
- the application concentrations in the cleaning liquor are about 2 to 8 g / 1, preferably 2 to 5 g / 1.
- the rinse program is generally supplemented and ended with a few intermediate rinse cycles with clear water and a rinse cycle with a common rinse aid following the cleaning cycle. After drying, not only are completely clean dishes which are an from a hygienic point of view, but above all also bright silver silver cutlery.
- Silver spoons (type WMF, hotel cutlery, form Berlin) were cleaned with a silver cleaner, degreased with gasoline and dried. Three spoons each were then placed in the cutlery basket of a Bosch S 712 household dishwasher (HGSM). The cleaning program (65 ° C, 16 ° dH) was now started and 50 g of a soiling (-0 and 30 g of the detergent) were metered directly into the machine. After the rinsing and drying process had ended, the HGSM were opened for 10 minutes, The machine was closed again and rinsed again in the same way. After the 10th rinse cycle, the spoons were removed and evaluated.
- HGSM Bosch S 712 household dishwasher
- 16 l of cold city water (16 ° d) are briefly heated to boiling in a water treatment boiler.
- 96 g of black tea are left to draw in the nylon net with the lid closed for 5 minutes and the tea is transferred to a dipping apparatus with heating and stirrer.
- teacups are immersed 25 times in one-minute intervals at 70 ° C in the prepared tea infusion.
- the cups are then removed and placed on a tray with the opening facing down to dry.
- TAED Machine dishwashing detergents of the following compositions were also prepared (see Table 4).
- the compounds A - M were used as silver corrosion inhibitors: A: p-hydroxyphenylglycine B: 2,4-diaminophenol C: 5-chloro-2,3-pyridinediol D: 1- (p-aminophenyl) morpholine E: ascorbic acid F: N-monomethylglycine G: N, N-dimethylglycine H: 2-hydroxy-4-aminopyrimidine I: 2,4-dihydroxy-5-methylpyrimidine K: indole L: methionine M: 2-phenylglycine
- Ci2-Ci4-fatty alcohol ethoxylate (2E0) (Dehydol LS2 from Henkel) 1 0.75 1 1 0.75 1 1 0.75 1
- Silver corrosion inhibitor AM (A) (B) (C) (0) (E) (F) (G) (H) (I) (K) 1 1 1 1 2 2 2 3 pH value of a 1% aqueous 10 , 5 11 9.5 10.5 11 9.5 10.5 11 9.5 10.5 solution

- the silver spoons were consistently rated 0 to 1, i.e. "no to very weak tarnishing", rated. Identical compositions, but without silver corrosion inhibitor A - D in each case caused yellow to violet colors on silver spoons (rating: 2 to 4).
- Electrolytes and electrodes are Electrolytes and electrodes:
- the experiments were carried out in a Duran glass cell.
- the counterelectrode consisted of a gold plate (99.99% pure) with an area of 1 cm ⁇ .
- a Hg / Hg0 / 0.1 m NaOH electrode was chosen as the reference electrode, which was connected to the electrolytes via a Haber-Luggin capillary.
- the measurements were carried out with 5 g / 1 cleaner in tap water of 16 ° d and a salt load of approx. 600 mg (dry residue).
- the low-alkaline basic product (see above) was first dissolved and the solution heated to 65 ° C.
- the bleach and the bleach activator were used immediately before the measurement and / or the silver anticorrosive agent is added.
- the electrochemical measurement was then carried out. During the electrochemical experiments, the electrolyte solutions were heated to 65 ° C and flushed with air.
- the electrode potential was increased at a constant speed starting from -0.62, V based on the standard hydrogen electrode (SHE). After a total increase of 1.1 V, the potential was subsequently lowered at the same rate.
- a standard potentiostat consisting of a positive feedback amplifier, differential amplifier, adder and impedance converter and a function generator (Prodis 16 from Intelligent Controls CLZ GmbH) were used for this purpose.
- the corrosion behavior was characterized on the basis of current-voltage curves.
- Essential information comes from the zero crossing of the current voltage curve (rest potential, which arises automatically even without external influence on the potential) and the slope of the curve at the zero crossing (reciprocal polarization resistance)
- the addition of the silver corrosion inhibitor shifts the potential for zero crossing to lower values and the slope decreases. The silver corrosion is thus also considerably reduced by the addition of the silver corrosion protection agents.
