Abstract

The invention relates to the use of (oxidized) thioethers of alcohol alkoxylates in detergents and cleaning agents, especially in dishwashing detergents, and to detergents and cleaning agents, especially dishwashing detergents, containing (oxidized) thioethers of alcohol alkoxylates. Said (oxidized) thioethers are especially suitable for use as surfactants having rinse aid function (rinse aid surfactants). The term "oxidized" refers to the sulfur atom in the thioether, which may be present in oxidized form as a sulfoxide (SO) or sulfonyl (SO2).

Description

Use of optionally oxidized thioethers of alcohol alkoxylates in detergents and cleaning agents Description The present invention relates to the use of (oxidized) thioethers of alcohol alkoxylates in washing and cleaning compositions, especially in dishwashing compositions, and to washing and cleaning compositions, especially dishwashing compositions, which comprise (oxidized) thioethers of alcohol alkoxylates. These (oxidized) thioethers are especially suitable as surfactants with rinse aid function (rinse aid surfactants).
"Oxidized" relates to the sulfur atom in the thioether, which may be present in oxidized form as sulfoxide (SO) or sulfonyl (SO2).
Surfactants are substances which can lower interfacial tension. Typically, surfactants possess a characteristic structure and have at least one hydrophilic and at least one hydrophobic functional group. When the two parts of the molecule are in equilibrium with respect to one another, the substance will accumulate and become aligned at an interface, i.e. hydrophilic groups point, for example, into an aqueous phase and the hydrophobic groups in the direction of other solid, liquid or gaseous phases.
A further special feature of surfactants is the formation of higher aggregates, known as micelles.
In these, the surfactant molecules become ordered in such a way that the polar groups, for example, form a spherical surface. This has the effect that substances such as soil particles are solubilized in an aqueous solution with formation of micelles.
Surfactants are therefore suitable especially for cleaning surfaces and as an additive in washing compositions.
Surfactants which have a hydrophobic block and a hydrophilic block are widespread.
However, their tendency to form foam makes them unsuitable or suitable only to a limited degree for many applications. For applications in which strong foam formation is unwanted, therefore, nonionic surfactants which have a second hydrophobic block have been developed, which limits the foam volume.
The second hydrophobic block can derive, for example, from a fatty alcohol.
However, the use of dishwashing compositions which comprise such a surfactant, especially of dishwashing compositions for machine dishwashers, frequently leads to residues remaining on the dishware cleaned therewith (deposit formation; called "spotting" in the case of formation of spot deposits or "filming" in the case of film-like deposits).
The second hydrophobic block can alternatively derive from a fatty acid. In the case of dishwashing compositions which comprise such surfactants, the problem of deposit formation is no longer as great; however, these surfactants are hydrolysis-sensitive due to the ester group, which greatly restricts the usability thereof in alkaline formulations and at relatively high temperatures, especially in prolonged washing operations.
Thioethers of alcohol alkoxylates and the oxidized form thereof (i.e. the sulfoxides and sulfones) are known in principle; for example from US 3,627,845. This document describes the use of such compounds as biologically active compositions, for example as fungicides, acaricides and anthelmintics, and as surface-active substances in agrochemical formulations and coating compositions. Use as a washing or cleaning composition is not mentioned.
It was an object of the present invention to provide compounds which do not have the disadvantages of the prior art surfactants. More particularly, the compounds should have no strong tendency, if any, to foam formation; they should leave behind a lower level of residues, especially spotting residues, on the dishware washed therewith, and they should at least be less hydrolysis-labile, if at all, than the surfactants based on fatty acid esters. More particularly, the compounds should, however, have a maximum melting point such that they can also be formulated in solid washing and cleaning compositions.
The object is achieved by the use of compounds of the formula I

The remarks which follow regarding preferred embodiments, especially regarding preferred embodiments of the compounds I, the use thereof and the compositions comprising them, apply either taken alone or in any conceivable combination with one another. Unless anything is mentioned to the contrary, the remarks apply both to the inventive use and to the inventive washing and cleaning compositions.
The compounds I being used in accordance with the invention may be chemically pure substances or mixtures of different compounds I. In general, due to the production process therefor and the reactants used therein, which may be technical-grade products or product mixtures, mixtures of different compounds I will be involved, which differ, for example, in the definition of the variables R, R', I, m, n and/or x.
In the compounds I, R is preferably C8-C15-alkyl, more preferably Clo-C15-alkyl and especially C10-C14-alkyl. In a specific embodiment, the alkyl radical R is branched.
Specific examples of R are 2-propylheptyl, tridecyl and the positional isomers thereof, such as isotridecyl (i.e. branched tridecyl radicals and mixtures thereof), n-dodecyl (lauryl), n-tetradecyl (myristyl) and mixtures thereof.
R' is preferably Clo-C14-alkyl and especially C12-alkyl (dodecyl); especially n-dodecyl.
R1 and R2 are preferably each independently methyl.
m is preferably from 20 to 50, more preferably from 25 to 50, even more preferably from 25 to 45 and especially from 25 to 40.

I and n are preferably each independently from 0 to 5 and more preferably 0, 1, 2 or 3.
More particularly, I and n are each 0.
When at least one of the indices I or n is not 0, the ethyleneoxy repeat units (-CH2-CH2-5 0-) and the different repeat units (-CH2-CH(R1)-0-) and/or (-CH2-CH(R2)-0-) may be arranged randomly or in blocks. They are preferably arranged in blocks; in other words, all I repeat units -CH2-CH(R1)-0- which may be present form a block which is followed by ethyleneoxy block (-CH2-CH2-0-)m which is followed by all n repeat units -CH(R2)-0- which may be present as a block.
xis preferably 0 or 1.
The compounds I are notable for a relatively high melting point. The melting point is preferably at least 35 C, for example 35 to 50 C, preferably 35 to 47 C and especially 35 to 45 C; more preferably at least 38 C, for example 38 to 50 C, preferably 38 to 47 C and especially 38 to 45 C; and especially at least 40 C, for example 40 to 50 C, preferably 40 to 47 C and especially 40 to 45 C.
Processes for preparing compounds I are known in principle; for example from US
3,627,845. For instance, in the case that I is not 0, an alcohol R-OH can be reacted with an epoxide and then with ethylene oxide.
In the case that n is not 0, the product obtained is then reacted with an epoxide R2.
This is followed by the reaction with a mercaptoethanol R'-S-CH2CH2-0H to give the compound I. If x should be 1 or 2, the thioether obtained is subsequently oxidized.
The reaction with the epoxides is effected preferably in an anhydrous medium under base catalysis. The reaction is preferably effected under inert gas atmosphere, such as nitrogen or argon. The reaction is preferably performed in bulk, i.e. without further solvents. Suitable bases are, for example, inorganic bases, such as alkali metal hydroxides, e.g. lithium, sodium or potassium hydroxide, alkaline earth metal hydroxides, e.g. magnesium or calcium hydroxide, alkali metal carbonates, e.g.
lithium, sodium or potassium carbonate, or alkaline earth metal carbonates, e.g.
magnesium or calcium carbonate. Preference is given to sodium hydroxide and potassium hydroxide.
The reaction temperature is preferably 50 to 200 C, more preferably 100 to 150 C. The reaction is effected preferably under elevated pressure, for example at 1.1 to 10 bar or 1.2 to 5 bar, which is built up by the inert gas and/or the epoxide (especially ethylene oxide). In a preferred embodiment, introduction of the epoxide is preceded by buildup of an initial pressure with inert gas, generally nitrogen. This initial pressure is preferably in the range from 1.1 to 5 bar, more preferably from 1.2 to 3 bar and especially from 1.2 to 2 bar. The addition of the epoxide (especially ethylene oxide) generally then leads to a further pressure increase. The pressure during the actual reaction is in the range from preferably 1.2 to 10 bar, more preferably from 2 to 8 bar. On completion of conversion, the product mixture obtained can be neutralized if desired.
The condensation with the mercaptoethanol is effected preferably under acidic catalysis. Suitable acids are, for example, p-toluenesulfonic acid, methanesulfonic acid, phosphoric acid and acidic ion exchangers. During the reaction, the water of reaction formed is preferably removed, for example by azeotropic distillation or stripping with an inert gas. If the water of reaction is to be removed by azeotropic distillation, the condensation is advantageously performed in a solvent which forms a minimum azeotrope with water, such as toluene or the xylenes. On completion of conversion, the product mixture obtained can be neutralized if desired.
The sulfur atom in the thioether obtained can be oxidized to the sulfoxide (x = 1) or sulfone (x = 2) by means of customary oxidizing agents, such as hydrogen peroxide, manganese dioxide, a permanganate, m-chloroperbenzoic acid or a perchlorate.
Whether the oxidation proceeds up to the sulfoxide or up to the sulfone can be determined by factors including the selection of the oxidizing agent, the concentration thereof and the reaction temperature.
The compounds I can be used in accordance with the invention in the form of the solution obtained in the preparation thereof. However, they are preferably isolated by means of customary processes and purified if desired.
The compounds of the formula I are usable in principle in all common washing and cleaning compositions.
In the context of the present invention, washing compositions are understood to mean those compositions which are used for cleaning of flexible materials with high absorptivity, for example of materials with textile character, whereas cleaning compositions in the context of the present invention are understood to mean those compositions which are used for cleaning of materials with a continuous surface, i.e.
with a surface which has only few and small pores, if any, and as a result has only low absorptivity, if any.
Examples of flexible materials with high absorptivity are those which comprise or consist of natural, synthetic or semisynthetic fiber materials, and which accordingly generally at least partially have textile character. The fibrous materials, or those consisting of fibers, may in principle be present in any form which occurs in use or in production and processing. For example, fibers may be present in unordered form in the form of staple or aggregate, in ordered to form in the form of fibers, yarns, threads, or in the form of fabrics such as nonwovens, lodens or felt, wovens, knits, in all conceivable binding types. The fibers may be raw fibers or fibers in any processing state. Examples are natural protein or cellulose fibers, such as wool, silk, cotton, sisal, hemp or coconut fibers, or synthetic fibers, for example polyester, polyamide or polyacrylonitrile fibers.
Examples of materials which have only few and small pores, if any, and have only low absorptivity, if any, are metal, glass, enamel or ceramic. Typical objects made of these materials are, for example, metal sinks, cutlery, glass and porcelain dishware, bathtubs, washbasins, tiles, flags, hardened synthetic resins, for example decorative melamine resin surfaces on kitchen furniture, or finished metal surfaces, for example refrigerators and automobile bodies, printed circuit boards, microchips, sealed or varnished wood, for example parquet or wall paneling, window frames, doors, plastic coverings such as floor coverings made of PVC or hard rubber, or hard or soft foams with substantially continuous surfaces.
Examples of cleaning compositions which comprise the compounds I comprise dishwashing compositions, such as manual dishwashing compositions or machine dishwashing compositions (= dishwashing compositions for the machine dishwasher), metal degreasers, glass cleaners, floor cleaners, all-purpose cleaners, high-pressure cleaners, neutral cleaners, alkaline cleaners, acidic cleaners, spray degreasers, dairy cleaners, industrial kitchen cleaners, equipment cleaners in industry, especially in the chemical industry, cleaners in car washes, and also domestic all-purpose cleaners.
The compounds I are preferably used in dishwashing compositions. They are more preferably used in machine dishwashing compositions. Among these, preference is given to dishwashing compositions, especially machine dishwashing compositions, with rinse aid function.

The washing and cleaning compositions which comprise the compounds I are preferably solid at room temperature (20 C).
The solid washing and cleaning compositions may be pulverulent or tableted products ("tabs"). They are preferably tableted products ("tabs"). More preferably, they are tableted dishwashing compositions, especially tableted machine dishwashing compositions.
Tableted dishwashing compositions may be simple tabs or else what are called "2 in 1", "3 in 1", "5 in 1", "7 in 1" products and the like (multifunctional products; generally speaking "x in 1" products where x = integer). Further details of these formulations can be found in Hermann G. Hauthal, G. Wagner (eds.), Reinigungs- und Pflegemittel im Haushalt [Domestic Cleaning and Care Compositions], Verlag fur chemische Industrie, H. Ziolkowsky GmbH, Augsburg 2003, chapter 4.2, pages 161-184. "2 in 1"
products comprise, as well as the customary constituents of machine dishwashing compositions, additionally a rinse aid. "3 in 1" products also comprise a water softener. "5 in 1"
products generally also comprise a glass protector and a rinsing power enhancer. "7 in 1" products also comprise a precious metal brightener and an encrustation remover.
The compounds I are preferably used in tableted multifunctional machine dishwashing compositions, where they completely or partially replace the customary rinse aids.
The compounds I have an effect both as a surfactant and as a rinse aid. The invention therefore also relates to the use of the compounds I as a surfactant and/or as a rinse aid. More particularly, the invention relates to the use of the compounds I as a surfactant with rinse aid effect or as a rinse aid surfactant.
The compounds I used in accordance with the invention are notable especially for excellent deposition-inhibiting action in the case of use in the rinse cycle of the machine dishwasher. They have inhibiting action both with respect to inorganic deposits and with respect to organic deposits. The inorganic deposits are especially calcium and magnesium phosphate, calcium and magnesium carbonate, calcium and magnesium silicate and/or calcium and magnesium phosphonate, which form from the calcium and magnesium salts present in the water and the builders present in customary dishwashing compositions. The organic deposits are especially soil constituents from the rinse liquor, for example protein, starch and grease deposits. The compounds I used in accordance with the invention are also effective against what are called carry-over deposits, which originate from the residual amount of water in the bottom of the dishwasher and comprise, inter alia, dishwashing composition residues and possibly also soil residues from the previous wash cycle of the machine dishwasher.
The invention further provides washing or cleaning compositions which comprise at least one compound of the formula I. With regard to suitable washing or cleaning compositions, reference is made to the above remarks.

Particularly effective bleach catalysts are manganese complexes, which are described, for example, in WO-A 94/21777. In the case of use thereof in the washing and cleaning compositions, such compounds are incorporated at most in amounts up to 1.5% by weight, especially up to 0.5% by weight, and in the case of very active manganese complexes in amounts up to 0.1% by weight. In addition to the described bleach system composed of bleaches, bleach activators and optionally bleach catalysts, it is also possible to use systems with enzymatic peroxide release or photoactivated bleach systems for the inventive washing and cleaning compositions.
Surfactants from group e) other than component a) may be cationic, anionic, zwitterionic or nonionic.
Suitable nonionic surfactants are, for example, alkoxylated, advantageously ethoxylated, especially primary alcohols having preferably 8 to 18 carbon atoms and an average of 1 to 20, preferably 1 to 12, mol of ethylene oxide (E0) per mole of alcohol, in which the alcohol radical may be linear or preferably 2-methyl-branched, or may comprise linear and methyl-branched radicals in a mixture, as are typically present in oxo alcohol radicals. Especially preferred, however, are alcohol ethoxylates with linear radicals formed from alcohols of native origin having 12 to 18 carbon atoms, for example from coconut alcohol, palm alcohol, tallow fat alcohol or oleyl alcohol, and an average of 2 to 8 EO per mole of alcohol. The preferred ethoxylated alcohols include, for example, C12-C14-alcohols with 3 E0, 4 EO or 7 E0, Cs-C11-alcohol with 7 E0, 013-C15-alcohols with 3 E0, 5 E0, 7 E0 or 8 E0, C12-C18-alcohols with 3 EO, 5 EO

The degrees of ethoxylation stated are statistical averages which, for a specific product, may be an integer or a fraction. Also suitable are alcohol ethoxylates which have a narrowed homolog distribution (narrow range ethoxylates, NRE). In addition to these nonionic surfactants, it is also possible to use fatty alcohols with more than 12 E0. Examples thereof are tallow fat alcohol with 14 EO, 25 EO or 30 EQ. It is also possible to use nonionic surfactants which comprise EO and PO
groups together in the molecule. In this case, it is possible to use block copolymers with E0-PO block units or P0-E0 block units, but also E0-P0-E0 copolymers or P0-E0-P0 copolymers. It will be appreciated that it is also possible to use mixed-alkoxylation nonionic surfactants in which EO and PO units are not in blockwise but in random distribution. Such products are obtainable by the simultaneous action of ethylene oxide and propylene oxide on fatty alcohols.
In addition, further nonionic surfactants used may also be alkyl glycosides of the general formula (1) RaO(G)y (1) in which Ra is a primary straight-chain or methyl-branched, especially 2-methyl-branched, aliphatic radical having 8 to 22, preferably 12 to 18, carbon atoms and G is a glycoside unit having 5 or 6 carbon atoms, preferably glucose.

is a linear or branched polyhydroxyalkyl radical having 3 to 10 carbon atoms and 3 to 10 hydroxyl groups. The polyhydroxy fatty acid amides are known substances which can be obtained typically by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine, and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.
The group of the polyhydroxy fatty acid amides also includes compounds of the formula (3) moi ot tatty acid, or in tne transestentication ot trigiycendes with O.:3 to 2 mol ot glycerol. Preferred sulfonated fatty acid glyceryl esters are the sulfonation products of saturated fatty acids having 6 to 22 carbon atoms, for example of caproic acid, caprylic Rf¨O¨Rg [Z]i (3) in which Re is a linear or branched alkyl or alkenyl radical having 7 to 12 carbon atoms, Rf is a linear, branched or cyclic alkylene radical having 2 to 8 carbon atoms or an arylene radical having 6 to 8 carbon atoms, and Rg is a linear, branched or cyclic alkyl radical or an aryl radical or an oxyalkyl radical having 1 to 8 carbon atoms, preference being given to C1-C4-alkyl or phenyl radicals, and [Z]l is a linear polyhydroxyalkyl radical, the alkyl chain of which has been substituted by at least two hydroxyl groups, or alkoxylated, preferably ethoxylated or propoxylated, derivatives of this radical. [Z]l is preferably obtained by reductive amination of a sugar, for example glucose, fructose, maltose, lactose, galactose, mannose or xylose. The N-alkoxy- or N-aryloxy-substituted compounds can then be converted, for example according to WO-A-95/07331, to the desired polyhydroxy fatty acid amides by reaction with fatty acid methyl esters in the presence of an alkoxide as a catalyst.
Suitable anionic surfactants are, for example, those of the sulfonate and sulfate type.
Useful surfactants of the sulfonate type preferably include C9-C13-alkylbenzenesulfonates, olefinsulfonates, i.e. mixtures of alkene- and hydroxyalkanesulfonates and disulfonates, as obtained, for example, from C12-monoolefins with terminal or internal double bonds by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products. Also suitable are alkanesulfonates, which are obtained from C12-C15-alkanes, for example, by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization.

Additionally preferred are alk(en)yl sulfates of the chain length mentioned, which comprise a synthetic straight-chain alkyl radical which has been produced on a petrochemical basis and which has analogous degradation behavior to the equivalent compounds based on fatty chemical raw materials. From the point of view of washing, the C12-C15-alkyl sulfates and Cu-Cm-alkyl sulfates, and also alkyl sulfates, are preferred. 2,3-Alkyl sulfates, which are prepared, for example, according to US patents 3,234,258 or 5,075,041 and can be obtained as commercial products from Shell Oil Company under the DAN name, are also suitable anionic surfactants.
The sulfuric monoesters of the straight-chain or branched C7-C21-alcohols which have been ethoxylated with 1 to 6 mol of ethylene oxide, such as 2-methyl-branched alcohols with an average of 3.5 mol of ethylene oxide (EO), or C12-C18 fatty alcohols with 1 to 4 EO, are also suitable. Owing to their high foaming level, they are used in cleaning compositions only in relatively small amounts, for example in amounts of 1 to 5% by weight.
Further suitable anionic surfactants are also the salts of alkylsulfosuccinic acid, which are also referred to as sulfosuccinates or as sulfosuccinic esters, and which are monoesters and/or diesters of sulfosuccinic acid with alcohols, preferably fatty alcohols and especially ethoxylated fatty alcohols.

The compounds I used in accordance with the invention are notable for a high melting point compared to customary prior art surfactants, which allows the use thererof in solid washing and cleaning compositions. They have no strong tendency, if any, to form foam, they have a good deposit-inhibiting action on dishware washed therewith, especially in relation to spotting, and they are not hydrolysis-labile.

The application is now illustrated further by the nonlimiting examples which follow.
Examples 1. Synthesis examples General method 1.1 Preparation of alkyloxy ethylene glycol dodecylmercaptoethanols 1.1.1 Preparation of the alcohol ethoxylate:
In a 2 I autoclave from Mettler, the alcohol to be alkoxylated (isotridecanol, propylheptanol or C12/C14-alcohol; 1.0 eq) is admixed with an aqueous KOH
solution which comprises 50% by weight of KOH. The amount of KOH is 0.2% by weight of the product to be prepared. While stirring, the mixture is dewatered at 100 C and 20 mbar for 2 h. This is followed by purging three times with N2, establishing an initial pressure of approx. 1.3 bar of N2 and increasing the temperature to 120 C. The ethylene oxide (n mol eq.) is metered in such that the temperature remains between 125 and 135 C.
This is followed by stirring at 125 C for a further 5 h, purging with N2, cooling to 70 C
and emptying the reactor. The crude product is degassed on the rotary evaporator at 100 C (<20 mbar) for 2 h. This basic crude product can be deionized with commercial magnesium silicates, which are subsequently filtered off. Alternatively, the neutralization can also be performed with the aid of acetic acid. The light-colored product is characterized with the aid of 1H NMR spectrum in CDCI3 and gel permeation chromatography, and also an OH number determination, and the yield is determined (>98%).
1.1.2 Reaction with dodecylmercaptoethanol A 500 ml apparatus with a water trap is initially charged with the alkoxylate from example 1.1.1 (1 mol eq.), para-toluenesulfonic acid (0.005 mol eq.) and toluene. The reaction mixture is heated to reflux. Dodecylmercaptoethanol (x mol eq.) is added dropwise. The water which forms is removed by means of a water trap overnight.
The reaction mixture is cooled, neutralized with sodium carbonate (0.005 mol eq.), filtered and freed completely of the solvent at 100 C and 6 mbar. This gave a white solid product. The structure was determined by TAI NMR (`)/0 OH groups converted).
The =

residual amount of toluene (always <0.5%) and dodecylmercaptoethanol was determined by means of GC.

71.6 g of the above-described product C (40 mmol, 1 mol eq.) were melted in a 250 ml flask, introduced into water and heated to 70 C. Hydrogen peroxide (50%) (4.1 g, 60 mmol, 1.5 mol eq.) was added dropwise. The reaction mixture was stirred at for 2 hours, then cooled and concentrated at 100 C and 6 mbar. This gave 69.2 g (96%
yield) of a solid yellow product. The absence of hydrogen peroxide was checked by means of IR, and the conversion (100%) was determined by means of 1H NMR.
Method description for TAI NMR:
In order to be able to (quantitatively) determine signals of primary and/or secondary alcohols superimposed in the 1H NMR spectrum, a sample in CDCI3 is admixed with an excess of TAI (trichloroacetyl isocyanate). The isocyanate reacts immediately with the alcohol groups to give the carbamate. The compounds CI3CC(0)NHC(0)-00-12R or CI3CC(0)NHC(0)-OCH-RR' present therein have different, typical shifts for OCH2 and OCHRR' in the 1H NMR spectrum.
The typical shift range for "primary carbamates" is 4.0 to 4.5 ppm, while that for "secondary carbamates" is 5.0 to 5.3 ppm.

For this purpose, 10 ml of beaten chicken egg, 19 g of a base dishwashing composition (48 parts sodium metasilicate x 5H20, 45 parts sodium triphosphate, 5 parts sodium carbonate) and 1 g of the surfactant (A-F) were introduced into the dishwasher (Miele Desinfektor CD MCU; programmable control unit MCU version SO4.01). At different temperatures, the number of rotations of the spray arm was then measured. The spray arm is slowed down at a high foam level; it can work with the highest possible speed (approx. (125 rpm) at a low foam level. The peak speed of the dishwasher is usually approx.
125 rpm when no foam is present. The maximum speed in the machine dishwasher was set artificially in the present test (by means of bores on the spray arm, position of the =

nozzles), in order to obtain a broader range which allows better distinction of the products.
The rotation rate was measured at 40, 50 and 60 C. The table which follows lists the 5 rotor speeds in rpm at different temperatures.

All rinse aid tests were carried out in a Miele machine dishwasher (G1222 SCL). The program at 50 C (R time 2) was selected for the wash cycle, and 65 C for the rinse cycle. The tests were conducted with hardened water with water hardness 21 dH

(Ca/Mg):HCO3 (3:1):1.35. No separate rinse aid was added, and the incorporated water softener (ion exchanger) was not regenerated with regenerating salt. The abovementioned formulation was used in a dosage of 21 g in each case. For each rinse cycle, 100 g of ballast soil consisting of grease, protein and starch was added.
The test dishware in each cleaning cycle was Cronnargan knives, blue melamine plates, glasses and porcelain plates. Between the rinse cycles, there was a wait period of one hour in each case, 10 min with the door closed, 50 min with the door open.
After the sixth rinse cycle had ended, the dishware was inspected visually in a darkened chamber under light behind an aperture plate, and assessed according to a scale of marks from 1 (= severe residues) to 10 (= no residues) with regard to deposits in the form of spots, streaks and films.
