GERUSTSTOFFHALTIGE DETERGENT MIXTURE
It istbekannt that one receives a increased Relnigungskraft and/or white degree maintenance with the additive of stand materials to that and/or the active synthetic Detergenskomponenten of detergent mixtures, and zw. even if the used washing solution a smaller quantity of the active Detergens contains D n. Cleaning strength is the ability of a solution of the Detergenszusammensetzung for the distance of dirt from fabrics. By white degree maintenance the ability of a washing solution is to be understood to prevent suspended dirt to the Abscheldung on the fabric during the washing process. The expression “Detergenswirkung”, how it is used in the context of the invention, covers both cleaning strength and Weißgradaufrechterhalümg.
Stand material effects sindim observed connection with different inorganic salts, like alkali metal carbonates, - bicarbonate, - borate, - phosphates and - sflikate. The best inorganic stand materials are the water-soluble polyphosphates and in particular the water-soluble Pyrophosphate of and tripolyphosphates. Used of this will sodium tripolyphosphate as Gerüststoffam most frequent in firm Waschmi elmischungen. With the beginning of the liquid Wascbm water-soluble Pyrophosphate ttelmischungen is generally preferred, because the tripolyphosphates show the tendency towards the hydrolysis in aqueous solution at long storage periods, whereby something Pyrophosphat and something orthophosphate is formed, welch' a latter less effective Gerüstsboff represents and under other disadvantages a harmful effect on the softness of the treated fabrics shows. Also sometimes in liquid beginnings potassium salts of inorganic stand materials are used, whereby by the advantage of their larger solubility use is made.
The kind of the stand material effect is clarified not completely. A connection between the ability of a stand material seems for plasticizing the water, which is used for the beginning by washing solution to exist, and the improved results regarding cleaning strength, which will receive, if the Gerüstsboff is used. Have themselves however not all materials, which work opposite harden-forming Kalziumund magnesium ions in an educated manner, when satisfying stand materials proved. In addition useful stand material effects with the most effective stand materials can be determined above and below the point, with soft the stand material in the Wasehlösung in stoichiometric portions regarding the water hardness are present.
gungsproduktenwerdenVerbindungen in many Wasch-und pure, like sodium tripolyphosphate, applied, which bind and prevent Kalziumund magnesium ions in solution complex, Trade Union of German Employees it Reinigungswirkungdes the surface-active Mißels affect disturbing. Another way to reach practically the same consists of falling the calcium and magnesium using different water-soluble inorganic compounds the anions, which with calcium and in a smaller paint with magnesium relatively insoluble precipitations form, contained. Examples of anions, which form precipitations with calcium and magnesium, are the carbonate, Silikatund AIurn nations. One of the main problems with the precipitation-forming stand materials, as they are descriptive above, is the separation of the formed precipitation on the washed fabrics. This is in particular then feeling, if colored fabrics are washed. Usual dirt suspending means, like Natriumcarboxymethylcellulose, are not qualified, the separation by the above Gerüstsü) ffe formed precipitations on colored fabrics, in particular after repetitive washing to prevent. Phosphatgerüstsboffe, which form a complex with the hardness ions, prevent this problem, but it now as wünschensweß proved to omit phosphates in Waschund Reinigungsmit±elprodukten.
Eutrophikation represents a natural procedure, which is oderFIüssenwesentlich for the maintenance of the life in lakes, in order to make the growth possible of the plants in the water and to supply fodder for the fish world in such a way.
One that principal interest validity today that excessive or accelerated Eutrophikation. A too strong plant growth in lakes and rivers leads to a consumption from the fish-needed Sauersboffs, whereby the correct ecological equilibrium in these waters is disturbed. This excessive Eutrophikation is caused by the excessive nutrients, which arrive in lakes and rivers. The phosphates, which are to be found in most generally used firm Waschund Reinigungsmißelmischungen, represent such nutrients. Phosphates as such cause however no excessive Eutrophikation.
Also different nutrients, like carbon and nitrogen, must be present. The combination of the nutrients stimulates that plant growth in lakes and rivers.
A goal of the invention is it to create biologically degradable Waschund ReinigungsmitteImischnngen those is phosphorus-free, since the presence of this element in lakes and rivers can contribute to the excessive or accelerated Eutrophikation.
Principal purpose of the invention is thereby the creation of a stand material system, with which fällend a working stand material is used, and thus the precipitation in the measure to modify that the separation of the precipitation on the fabrics which can be washed is prevented.
ZieI of the invention is to be also created it, Waschund cleaning agent system, which results in an effective Gerüststoffwlrkung einschlieffiich the removal of essentially all Kalziumund magnesium ions in the Wasehlösung.
In addition aims invention on creation of Wasch-und Reinlgungsmi elmischungen off, biologically degradable, nich¢phosphorhältige stand material mixtures contained, which in Waßserlösungen within comprehensive concentration range effective are, since the conditions, on which the Haushaltswäsehe takes place, in very strong measure vary due to individual and örtlinher conditions.
A goal of the invention is it also to obtain an intensified stand material effect in particular in Hochleisümgswaschmißelmisehungen.
The understanding goals are achieved according to invention by creation of gerüststoffhältigen detergent mixtures, existing lm substantial out:

The preferential salts are Kaliumund of sodium salts, like Natriumearbonat, - aluminate and - silicate, and potassium carbonate, - aluminate and - silicate.
The above description of the radio ion test for a precipitation modifier is necessary because of the completely unforeseeable nature of the connections, which correspond to the test. First that jedwedes means, which is suitable for the Komplexblldung by calcium in solution should be effective, but is not this was accepted not the case. From table 1 of the example 1 that Natriumbfsulfit is well work-cash, however calcium or magnesium does not follow at all complex binds. If this characteristic of the modification of the precipitation of harden-forming ions would stand in relationship with the ability of the Komplexbildung of any given connection, then the relative achievement, which is indicated in the example and according to which Xylotrihydroxyglutarsäure is superior Cyelopentan cis, to ice, ice tetracarbonsäure, welch' the latters again the Mellithsäure is superior, straight would have turned around, if their rank were considered as Komplexblldner, according to which the Melli would be hsäure first, Cyolopentan cis, ice, the cis tetracarbonsäure next and the Xylotrihydroxyglutarsäure the latter.
Furthermore is to be considered, chB both Polymaleinsäure and Polyacrylsäure with the molecular weight indicated in example 1 a certain complex education ability have, how only Polyacry! - acid as a FällungsmodifiziermiHel works.
The test indicated in example 1 was used, in order the ability of the specified connections to the ModifizierungderHärtefällungin WaschmiHelmischungen, which contains according to invention used a stand material system, to determine.
