Description

 cleaning supplies

The present patent application describes detergents or cleaning agents, in particular detergents for the machine cleaning of dishes. This application relates in particular to two-phase or multiphase machine dishwashing detergents which contain bleach catalysts.

Machine-washed dishes are often subject to more stringent requirements today than manually-washed dishes. Thus, a tableware that has been completely cleaned at first glance of food waste is then rated as not having any flaw if, after machine dishwashing, it still has discolorations which are based, for example, on the attachment of vegetable dyes to the dish surface.

In order to obtain spotless dishes, bleaching agents are used in automatic dishwashing detergents. To activate these bleaches and in order to achieve an improved bleaching effect during cleaning at temperatures of 60 ^° C. and below, automatic dishwasher detergents generally also contain bleach activators or bleach catalysts, with the bleach catalysts in particular having proven to be particularly effective.

European Patent Application EP 481 793 A1 (Unilever) discloses detergent tablets which contain sodium percarbonate, which, according to the teaching of this application, is preferably separated from other components which are detrimental to its stability, for example in a separate layer.

Bleach catalysts are used in automatic dishwasher detergents, preferably in the form of prefabricated granules. Thus, the European patents EP 458 397 B1 (Unilever), EP 458 398 B1 (Unilever) and EP 530 870 B1 (Unilever) describe bleach catalysts based on various manganese-containing transition metal complexes.

Processes for the preparation of bleach catalyst granules are disclosed in Laid-Open Applications EP 544 440 A2 (Unilever) and WO 95/06710 A1 (Unilever). Characteristic of the methods described therein is the use of large amounts of binders, which are optionally used as melts, this method includes cooling and / or drying stages, which requires the use of additional equipment such as fluidized bed plants.

However, despite their undisputed bleaching performance, the use of bleach catalysts may not yet be considered satisfactory to one skilled in the art. Thus, despite the use of bleach catalysts, in particular in low-alkaline, for example phosphate-free, automatic dishwashing often with unexpectedly poor bleaching effects. Furthermore, the storage stability of bleach catalyst-containing detergents often leaves something to be desired.

In view of this initial situation, it was therefore the object of the present application to provide a dishwasher detergent which has an improved cleaning performance, in particular on bleachable soiling.

Surprisingly, it has been found that the bleaching effect of automatic dishwashing detergents can be increased by the preparation of active substance combinations of bleach, bleach activator and bleach catalyst in two-phase or multiphase metering units with an optimized phase split.

A first subject of this application is therefore a two- or multi-phase detergent or cleaning agent, comprising a) a bleaching agent b) a bleach activator c) a bleach catalyst selected from the group of bleach-enhancing transition metal salts and transition metal complexes, characterized in that the bleach a) with at least one of the components b) or c) is present together in one phase of the washing or cleaning agent.

Characteristic of the two- or multi-phase detergents or cleaning agents according to the invention is the fact that the bleaching agent a) is present together with at least one of the components b) or c) in one phase of the washing or cleaning agent. The object of the claim thus comprises both two-phase or multi-phase detergents in which a partial quantity or the total amount of the bleaching agent a) with a partial amount of the components b) or c) is present together in one phase, as well as such two- or multi-phase washing - or cleaning agents, in which the total amount of the bleaching agent a) with the total amount of at least one of the components b) or c) is present together in one phase.

B) a bleach activator c) a bleach catalyst selected from the group of bleach-enhancing transition metal salts and transition metal complexes, characterized in that the total amount of bleach a) with the total amount of at least one of the components b) or c) is present together in one phase of the washing or cleaning agent.

It has proven to be particularly advantageous to formulate as large as possible a subset of the bleaching agent a) with the largest possible subset of one of the constituents b) or c) together in one phase. Preferred two- or multi-phase detergents or cleaners are therefore characterized in that at least 50 wt .-%, preferably at least 70 wt .-%, more preferably at least 90 wt .-% and in particular the total amount of in the two- or multi-phase washing or bleach containing a) together with at least 50 wt .-%, preferably at least 70 wt .-%, more preferably at least 90 wt .-% and in particular the total amount of one of the components b) or c) are present together in one phase / is present.

Further builders are the alkali carriers. Suitable alkali carriers are, for example, alkali metal hydroxides, alkali metal carbonates, alkali metal hydrogencarbonates, alkali metal sesquicarbonates, the cited alkali metal silicates, alkali metal silicates, and mixtures of the abovementioned substances. For the purposes of this invention, preference is given to using the alkali metal carbonates, in particular sodium carbonate, sodium hydrogencarbonate or sodium sesquicarbonate. Particularly preferred is a builder system comprising a mixture of tripolyphosphate and sodium carbonate. Also particularly preferred is a builder system comprising a mixture of tripolyphosphate and sodium carbonate and sodium disilicate. Because of their comparability with other builders punching low chemical compatibility with the other ingredients of detergents or cleaners, the alkali metal hydroxides are preferably only in small amounts, preferably in amounts below 10 wt .-%, preferably below 6 wt .-%, more preferably below 4 wt .-% and in particular below 2% by weight, in each case based on the total weight of the washing or cleaning agent. Particularly preferred are agents which, based on their total weight, contain less than 0.5% by weight and in particular no alkali metal hydroxides.

Particularly preferred is the use of carbonate (s) and / or bicarbonate (s), preferably alkali carbonate (s), more preferably sodium carbonate, in amounts of 2 to 50 wt .-%, preferably from 5 to 40 wt .-% and in particular from 7.5 to 30 wt .-%, each based on the weight of the washing or cleaning agent. Particular preference is given to compositions which, based on the weight of the washing or cleaning agent, contain less than 20% by weight, preferably less than 17% by weight, preferably less than 13% by weight and in particular less than 9% by weight of carbonate ( e) and / or bicarbonate (s), preferably alkali metal carbonate (s), particularly preferably sodium carbonate.

Particularly suitable organic co-builders are polycarboxylates / polycarboxylic acids, polymeric polycarboxylates, aspartic acid, polyacetals, dextrins, further organic cobuilders and phosphonates. These classes of substances are described below.

Useful organic builders are, for example, the polycarboxylic acids which can be used in the form of the free acid and / or their sodium salts, polycarboxylic acids meaning those carboxylic acids which carry more than one acid function. These are, for example, citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), if such use is not objectionable for ecological reasons, and mixtures of these. In addition to their builder effect, the free acids also typically have the property of an acidifying component and thus also serve to set a lower and milder pH of detergents or cleaners. In particular, citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any desired mixtures of these can be mentioned here.

Further suitable builders are polymeric polycarboxylates, for example the alkali metal salts of polyacrylic acid or of polymethacrylic acid, for example those having a relative molecular mass of from 500 to 70,000 g / mol.

For the purposes of this document, the molecular weights stated for polymeric polycarboxylates are weight average molar masses M _{w of} the particular acid form, which were determined in principle by gel permeation chromatography (GPC), a UV detector being used. The measurement was carried out against an external polyacrylic acid standard, due to its structural relationship with gives the investigated polymers realistic molecular weight values. These data differ significantly from the molecular weight data, in which polystyrene sulfonic acids are used as standard. The molar masses measured against polystyrenesulfonic acids are generally significantly higher than the molecular weights specified in this document.

Suitable polymers are, in particular, polyacrylates which preferably have a molecular weight of 2,000 to 20,000 g / mol. Because of their superior solubility, the short-chain polyacrylates, which have molar masses of from 2000 to 10000 g / mol, and particularly preferably from 3000 to 5000 g / mol, may again be preferred from this group.

In general, silver protectants selected from the group of triazoles, benzotriazoles, bisbenzotriazoles, aminotriazoles, alkylaminotriazoles and transition metal salts or complexes can be used in particular. Particularly preferred to use are benzotriazole and / or alkylaminotriazole.

In addition, cleaner formulations often contain active chlorine-containing agents which can markedly reduce the corrosion of the silver surface. In chlorine-free cleaners especially oxygen and nitrogen-containing organic redox-active compounds, such as di- and trihydric phenols, such as hydroquinone, pyrocatechol, hydroxyhydroquinone, gallic acid, phloroglucinol, pyrogallol or derivatives of these classes of compounds are used. Also, salt and complex inorganic compounds, such as salts of the metals Mn, Ti, Zr, Hf, V, Co and Ce are often used. Preferred here are the transition metal salts which are selected from the group of manganese and / or cobalt salts and / or complexes, especially preferred are the cobalt (ammin) complexes, the cobalt (acetate) complexes, the cobalt (carbonyl) complexes, the chlorides of cobalt or manganese and manganese sulfate. Also, zinc compounds can be used to prevent corrosion on the items to be washed.

The metal salts and / or metal complexes mentioned are contained in cleaning agents, preferably in an amount of 0.05 to 6 wt .-%, preferably 0.2 to 2.5 wt .-%, each based on the total agent.

Two- or multi-phase detergent or cleaning agent, characterized in that the two- or multi-phase detergent or cleaning agent further contains a silver protection agent which is present together with the bleaching agent a) in a phase of the detergent or cleaning agent, are preferred according to the invention.

Some exemplary formulations for preferred two or more phase silver protectant-containing detergents or cleaners can be found in the following Tables:

As perfume oils or fragrances, individual fragrance compounds, for example the synthetic products of the ester type, ethers, aldehydes, ketones, alcohols and hydrocarbons, can be used in the context of the present invention. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance. Such perfume oils may also contain natural fragrance mixtures such as those available from vegetable sources, such as pine, citrus, jasmine, patchouly, rose or ylang-ylang oil.

Preferred dyes, the selection of which presents no difficulty to the skilled person, have a high storage stability and insensitivity to the other ingredients of the agents and to light and no pronounced substantivity to the substrates to be treated with the dye-containing agents such as textiles, glass, ceramics or plastic dishes do not stain them.

In order to facilitate the disintegration of preformed moldings, it is possible to incorporate disintegration aids, so-called tablet disintegrants, into these compositions in order to shorten the disintegration times. By tablet disintegrants or disintegrants are meant excipients which ensure the rapid disintegration of tablets in water or other media and for the rapid release of the active ingredients.

These substances, which are also referred to as "explosives" due to their effect, increase their volume upon ingress of water, on the one hand increasing the intrinsic volume (swelling), and on the other hand creating a pressure via the release of gases which can break the tablet into smaller particles disintegrates. Well-known disintegration aids are, for example, carbonate / citric acid systems, although other organic acids can also be used. Swelling disintegration aids are, for example, synthetic polymers such as polyvinylpyrrolidone (PVP) or natural polymers or modified natural substances such as cellulose and starch and their derivatives, alginates or casein derivatives.

Disintegration aids are preferably used in amounts of from 0.5 to 10% by weight, preferably from 3 to 7% by weight and in particular from 4 to 6% by weight, based in each case on the total weight of the disintegration assistant-containing agent.

Furthermore, according to the invention, gas-evolving effervescent systems can furthermore be used as tablet disintegration auxiliaries. The gas-evolving effervescent system may consist of a single substance that releases a gas upon contact with water. Among these compounds, mention should be made in particular of magnesium peroxide, which liberates oxygen on contact with water. Usually However, the gas-releasing effervescent system in turn consists of at least two components which react with each other to form gas. While a variety of systems are conceivable and executable here, which release, for example, nitrogen, oxygen or hydrogen, the bubble system used in detergents and cleaners can be selected both on the basis of economic and environmental considerations. Preferred effervescent systems consist of alkali metal carbonate and / or bicarbonate and an acidifying agent which is suitable for liberating carbon dioxide from the alkali metal salts in aqueous solution.

As Acidifizierungsmittel which release carbon dioxide from the alkali metal salts in aqueous solution, for example, boric acid and alkali metal hydrogen sulfates, alkali metal dihydrogen phosphates and other inorganic salts can be used. However, preference is given to using organic acidifying agents, the citric acid being a particularly preferred acidifying agent.
