Description

object This application is automatic dishwashing detergent, in particular machine Dishwashing liquid with integrated rinse function.

At mechanically rinsed Dishes are common today higher Requirements placed as on manually rinsed dishes. So will be one of leftovers completely cleaned dishes then rated as not flawless when it after machine dishwashing still whitish, on water hardness or other mineral salts has stains that lack of wetting agent come from dried-up water drops.

Around To obtain glossy and spotless dishes, one sets therefore Today rinse aid with success one. The addition of rinse aid at the end of the washing program makes sure that this Water as possible completely from ware expires So that the different surfaces at the end of the washing program residue-free and immaculate shiny are.

The Machine cleaning of dishes in household dishwashers usually includes a prewash, a main wash and a rinse, which are interrupted by intermediate rinses. For most machines, the pre-rinse cycle is for heavily soiled dishes switchable, but is chosen only in exceptional cases by the consumer, so that in Most machines have a main wash, an intermediate wash with pure water and a rinse carried out become. The temperature of the main rinse varies depending on Machine type and program level selection between 40 and 65 ° C. In the rinse cycle from a dosing tank in the machine added rinse aid, which is usually contain nonionic surfactants as the main ingredient. Such rinse aid are in liquid Form and are widely described in the art. Your task consists mainly in limescale and deposits on the cleaned dishes to prevent. In addition to water and low-foaming nonionic surfactants this rinse aid often also hydrotopes, pH adjusters such as citric acid or deposit-inhibiting Polymers.

Around the disintegration of prefabricated moldings to facilitate, it is possible Disintegration aids, so-called tablet disintegrants, in to incorporate these agents to reduce disintegration times. Under Tablet disintegrants or disintegrators are adjuvants understood that for the rapid disintegration of tablets in water or other media and for the swift one Release of the active ingredients.

These Substances that are also referred to as "explosives" due to their effect increase when water enters their volume, on the one hand increasing the intrinsic volume (swelling), on the other hand also about the Release of gases can create a pressure on the tablet can disintegrate into smaller particles. Well-known Disintegration aids are, for example, carbonate / citric acid systems, although other organic acids can be used.

Pure cellulose has the formal gross composition (C ₆ H ₁₀ O ₅ ) _n and is formally a β-1,4-polyacetal of cellobiose, which in turn is composed of two molecules of glucose. Suitable celluloses consist of about 500 to 5000 glucose units and therefore have average molecular weights of 50,000 to 500,000. Cellulose-based disintegrating agents which can be used in the context of the present invention are also cellulose derivatives obtainable by polymer-analogous reactions of cellulose. Such chemically modified celluloses include, for example, products of esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. Celluloses in which the hydroxy groups have been replaced by functional groups which are not bonded via an oxygen atom can also be used as cellulose derivatives. The group of cellulose derivatives includes, for example, alkali metal celluloses, carboxymethylcellulose (CMC), cellulose esters and ethers, and aminocelluloses. The cellulose derivatives mentioned are preferably not used alone as disintegrating agents based on cellulose, but used in admixture with cellulose. The content of these mixtures of cellulose derivatives is preferably below 50% by weight, particularly preferably below 20% by weight, based on the cellulose-based disintegrating agent. It is particularly preferred to use cellulose-based disintegrating agent which is free of cellulose derivatives.

The particle sizes of such Disintegrating agents are usually above 200 microns, preferably at least 90 wt .-% between 300 and 1600 microns and in particular at least 90 wt .-% between 400 and 1200 microns.

As a further disintegrating agent based on cellulose or as a component of this component microcrystalline cellulose can be used. This microcrystalline cellulose is obtained by partial hydrolysis of celluloses under conditions which attack and completely dissolve only the amorphous regions (about 30% of the total cellulose mass) of the celluloses, leaving the crystalline regions (about 70%) intact. Subsequent deaggregation of the microfine celluloses resulting from the hydrolysis yields the microcrystalline celluloses which have primary particle sizes of about 5 μm and, for example, example, are compactable into granules with an average particle size of 200 microns.

preferred Disintegration aid, preferably a disintegration aid based on cellulose, preferably in granular, cogranulated or compacted form, are in disintegrating agents in amounts of from 0.5 to 10% by weight, preferably from 3 to 7% by weight and in particular from 4 to 6 wt .-%, each based on the total weight of the disintegrant-containing agent.

According to the invention preferred can about that in addition, gas-evolving effervescent systems as tablet disintegration aids be used. The gas-developing effervescent system can from a consist of a single substance which releases a gas on contact with water. Among these compounds is in particular the magnesium peroxide to call, which releases oxygen on contact with water. Usually However, the gas-releasing effervescent system in turn from at least two components that are together under gas formation react. While here a variety of systems is thinkable and executable, for example Nitrogen, oxygen or hydrogen will release the both in the detergents and cleaners used effervescent system on the basis of economic as well as ecological Select points of view to let. Preferred effervescent systems consist of alkali metal carbonate and / or bicarbonate and an acidifier, the is suitable to release carbon dioxide from the alkali metal salts in aqueous solution.

When Acidifying agents consisting of the alkali salts in aqueous solution Carbon dioxide release, for example, boric acid as well Alkali metal hydrogen sulfates, alkali metal dihydrogen phosphates and other inorganic salts can be used. However, preference is given used organic Acidifizierungsmittel, wherein the citric acid a particularly preferred acidifying agent. Preferred are Acidifier in effervescent system from the group of organic Di-, tri- and oligocarboxylic acids or mixtures.

When Perfume oils or Fragrances can in the context of the present invention, individual fragrance compounds, e.g. the synthetic products of the ester, ether, aldehyde, Ketones, alcohols and hydrocarbons are used. Prefers However, mixtures of different fragrances are used, the together create an appealing scent. Such perfume oils can also natural Contain fragrance mixtures, as they are accessible from plant sources, e.g. Pine, Citrus, Jasmine, Patchouly, Rose or Ylang-Ylang oil.

Around to be perceptible, a fragrance must be volatile, being next to the Nature of the functional groups and the structure of the chemical Compound also plays a role in the molecular weight. So own most fragrances have molecular weights up to about 200 daltons, while molar masses from 300 daltons and above constitute an exception. Due to the different volatility changed by fragrances the smell of a compound of several fragrances perfumes or perfume during Evaporation, whereby the odor impressions in "top note", "middle note" (middle note or body) and "base note" (end note or dry divided out). Because the smell perception to a large extent too on the smell intensity is based, the top note of a perfume or fragrance is not alone from volatile Connections while the base note for the most part from less volatile, i.e. adherent fragrances. When composing perfumes can be easier volatile For example, fragrances can be bound to specific fixatives. which prevents it from evaporating too quickly. At the following Classification of the fragrances in "lighter volatile or "adherent" fragrances So over the smell impression and about it, whether the corresponding perfume perceived as a head or middle note nothing is said.

The Fragrances can can be processed directly, but it can also be beneficial to the Fragrances on carrier The slow release of fragrance for long-lasting Provide scent. As such carrier materials For example, cyclodextrins have proven useful, with the cyclodextrin-perfume complexes additionally still can be coated with other excipients.

preferred Dyes whose selection does not present any difficulty to the skilled person have a high storage stability and insensitivity to the rest Ingredients of the agents and against light and no pronounced substantivity to the with the dye-containing agents to be treated substrates such as for example textiles, glass, ceramics or plastic dishes, so as not to stain them.

When choosing the colorant, it must be taken into account that the colorants have a high storage stability and insensitivity to light. At the same time, it should also be taken into account when choosing suitable colorants that colorants have different stabilities to oxidation. In general In my opinion, water-insoluble colorants are more stable to oxidation than water-soluble colorants. Depending on the solubility and thus also on the sensitivity to oxidation, the concentration of the colorant in the detergents or cleaners varies. In the case of readily water-soluble colorants, colorant concentrations in the range of a few 10 ^-2 to 10 ^-3 % by weight are typically selected. By contrast, in the case of the particularly preferred, but less readily water-soluble, pigment dyes due to their brilliance, the suitable concentration of the colorant in detergents or cleaners is typically about 10 ^-3 to 10 ^-4 % by weight.

It become colorants preferably, which can be oxidatively destroyed in the washing process and mixtures thereof with suitable blue dyes, so-called blue toners. It has proven to be advantageous to use colorants, the in water or at room temperature in liquid organic substances soluble are. Suitable are, for example, anionic colorants, e.g. anionic Nitroso.
