Abstract

The invention relates to a single or multi-phase detergent containing a surfactant, in particular to a hand dishwashing detergent. At least one phase contains shaped bodies, which are suitable for dispensing at least one detergent component in a time-release manner by being dissolved in water. The inventive detergent contains shaped bodies, which dispense the detergent or rinsing components in a time-release manner by being dissolved in water. According to the invention, the aforementioned 'encapsulated' components are not dispensed immediately after their addition to the water, i.e. during the production of the detergent or rinsing solution, but only after a specific time period. After the first cleaning or rinsing phase, for example the cleaning of glass, the user is thus provided with a detergent composition for the second cleaning or rinsing phase, the latter for example consisting of the cleaning of crockery and saucepans that have greasy deposits, said composition being optimised for this specific cleaning operation.

Description

Multiphase detergent

The present invention relates to detergent-containing detergents, in particular hand dishwashing detergents.

Conventional cleaning agents or hand dishwashing detergents are usually formulated as low-viscosity to viscous aqueous liquids. These practically exclusively single-phase formulated liquid cleaning or hand dishwashing detergents enable the user to easily produce the desired washing liquor or cleaning solution, which is also referred to as the application liquor, by diluting the cleaning or washing-up liquid concentrate without the user having to use the concentrated form of the agent comes into direct skin contact. Such skin contact is undesirable since the agents in concentrated form often have an irritating effect on the skin which the user perceives as unpleasant. Conventional single-phase hand dishwashing detergents and also cleaning agents usually contain water as the main constituent, in which the fat-dissolving and foam-active surfactants are dissolved.

A serious disadvantage of conventional hand dishwashing detergents is that after the hand dishwashing detergent concentrate has been diluted with water, the user inevitably has a certain surfactant mixture or detergent component mixture in a certain concentration range, depending on the dishwashing detergent used. The resulting wash liquor is then used for manual cleaning of the entire wash ware. However, it is known that a specific hand dishwashing detergent composition or surfactant concentration, which is matched to the respective wash ware, has or would have significantly better cleaning properties.

For example, when cleaning glass, it is desirable to achieve a good rinse aid effect, that is to say that the rinsing liquid should drain off without leaving any traces. A large amount of foaming is therefore undesirable when treating, cleaning and rinsing glasses. In addition, a high fat-dissolving power is generally neither necessary nor advantageous. The two The aforementioned properties, namely strong foaming and high grease-dissolving power are absolutely indispensable in the case of a hand dishwashing detergent, in particular if greasy soiling, for example on plates and pots, has to be removed. A hand dishwashing detergent optimized with regard to the cleaning of glasses or with regard to the rinse aid effect would therefore be less suitable for the removal of greasy soiling.

Since, for economic and ecological reasons, the user does not use a specifically designed hand dishwashing detergent for each special wash ware, the hand dishwashing detergent must inevitably contain all the components necessary for cleaning the respective wash ware. This has the consequence, for example, that when cleaning glass, which is usually carried out at the beginning of the washing process, with a universally applicable hand dishwashing detergent there is basically a strong foaming and a high fat-dissolving power, although, as stated above, this is undesirable or unnecessary ,

For the reasons mentioned above, it is also disadvantageous that any care products for the wash ware, for example care components for glass and ceramic surfaces, are contained in the wash liquor right from the start, namely with the addition of the hand dishwashing liquid. For understandable reasons, it would be advantageous if the care components were only added after the glasses had been cleaned.

Due to the usual schedule, one would first use a means for manual cleaning of glass to achieve an optimal cleaning effect and then clean dishes with heavily greasy soiling with the help of another agent with a different composition. In a further rinsing phase, the glass or dishes would possibly be treated with a rinsing liquor containing care components.

All previously known hand dishwashing detergents are not matched to the cleaning of the different items to be washed, which usually takes place in chronological phases or in steps, but rather represents a compromise in terms of Cleaning of, for example, glass, dishes with grease soiling, cutlery, etc. This applies both to the conventional single-phase and two-phase hand dishwashing detergents and, for example, to the previously described solid detergents and cleaning agents.

Similar disadvantages can also be observed in connection with cleaning agents, such as floor cleaners. By diluting the detergent concentrate, the user receives an appropriate cleaning solution or application liquor with a specific surfactant mixture or detergent component composition. The resulting cleaning solution thus contains, in addition to the dirt-dissolving substances, also appropriate care components which, for example, give the cleaned floor a glossy effect, provide the cleaned floor with a protective layer or are intended to prevent the cleaned surface from being soiled again quickly. As already stated, all detergent components, ie dirt-dissolving substances and care components, are forcibly applied to the surface to be cleaned when the agent is used. For understandable reasons, a gradual application of dirt-dissolving substances and care components would be advantageous, especially for heavily soiled surfaces, and would lead to a better cleaning result.

DE 198 54 267 relates to a coated active substance for manual cleaning agents for hard surfaces, such as hand dishwashing liquid. The casing preferably consists of a material which contains at least one natural or synthetic polymer or a mixture thereof and which dissolves in water at about 35 ° C. within about 10 to 50 seconds, preferably about 20 to 40 seconds. The detergents or dishwashing detergents based on coated active substances according to DE 198 54 267 are distinguished by improved storage stability, but do not have a formulation which is coordinated with the chronological course of a cleaning process and therefore have the disadvantages described above.

WO 94/14941 relates to aqueous neutral or slightly alkaline, automatic dishwashing detergents which are free from anionic and cationic surfactants. The Machine dishwashing detergents can be enclosed in water-soluble or water-dispersible containers, which consist, for example, of gelatin.

The automatic dishwashing detergents described in WO 94/14941, which may include enclosed or encapsulated detergent components, are unsuitable as hand dishwashing detergents. The gelatin coating of the active ingredients described in the documents only serves to stabilize the components and to allow simple dosing.

EP-A-9261754 relates to a foam bath in the form of a mixture of amine salts and long-chain alkyl ether sulfates and 25 to 35% by weight of liquid polyethylene glycols, encapsulated in an elastic gelatin capsule.

EP-A-0533 239 relates to aqueous liquid detergent compositions which comprise enzymes and encapsulated bleach particles. The cleaning agents are particularly suitable for use as automatic dishwashing agents. The encapsulation of individual components, namely the bleaching agents, also serves to improve the shelf life or stability here, since interactions between the enzyme and the bleaching particles are to be avoided.

It would therefore be very desirable to have a single detergent, in particular hand dishwashing detergent, which is optimized in terms of its composition and its cleaning effect with regard to the usual manual cleaning or rinsing process. The usual rinsing process for cleaning dishes includes manual cleaning of glass and subsequent cleaning of dishes with heavily greasy soiling.

It is now an object of the present invention to provide a cleaning agent, in particular hand dishwashing detergent, which overcomes the above-described disadvantages of conventional single- and multi-phase cleaning or hand dishwashing detergents. It is a particular object of the present invention that the composition of the cleaning or hand dishwashing detergent is coordinated and optimized with regard to the timing of the cleaning process and the surface to be cleaned or the items to be washed.

Further objects result from the following description of the invention.

The solution to the problems lies in the provision of a surfactant-containing detergent, in particular hand dishwashing detergent, the detergent being single-phase or multi-phase and wherein at least one phase has moldings which are suitable for releasing at least one detergent or detergent component when diluted with water with a time delay.

Delayed for the purposes of the present invention means that the shaped bodies dissolve when diluted with water at a specific point in time or during a specific period of time. In the context of the invention, the terms “detergent component” and “detergent component” also include auxiliaries and additives, such as, for example, perfume or dyes, in addition to cleaning-active substances.

The detergents or hand dishwashing detergents according to the invention are generally dissolved in water at a temperature of up to 50 ° C. and the resulting application liquor is then used, for example, for manual cleaning of hard surfaces and / or soft surfaces, in particular glasses, eating utensils and cookware etc. used. The term "manual cleaning" in the sense of the present invention naturally also includes a cleaning process which is carried out with the aid of mechanical aids, such as a brush, sponge or the like.

It has been found that the cleaning agent or hand dishwashing agent formulated according to the invention overcomes the disadvantages of the agents described in the prior art and enables an application liquor composition which is coordinated and optimized for the individual cleaning phases and rinsing phases. It is provided according to the invention that the cleaning agent, in particular rinsing agent, has at least one, preferably liquid phase, which dissolves essentially without any time delay when diluted with water. In a preferred embodiment, this immediately soluble phase contains the detergent or detergent components that are particularly suitable for the rinse effect on glass, since glasses or glass objects are first cleaned in a conventional manual rinsing process. The liquid phase particularly preferably contains detergent components selected from the group comprising nonionic surfactants, in particular end-capped Cβ-C ₂₂ alkyl alcohol polyglycol ethers, secondary alkane sulfonates, linear alkyl benzene sulfonates and alkyl polyglucosides.

In a further preferred embodiment, the liquid phase of the cleaning agent according to the invention contains between 5 and 45% by weight of surfactants, based on the liquid phase, preferably selected from the group comprising nonionic surfactants, anionic surfactants, betaines, amine oxides and cationic surfactants, the proportion of cationic surfactants is preferably less than 5% by weight.

Furthermore, the cleaning agent or hand dishwashing detergent according to the invention contains molded articles which contain the cleaning agents or detergents contained in the molded articles. Release detergent components with a time delay when diluted with water. According to the present invention, the aforementioned “encapsulated” components are not released into water immediately after the addition of the agent, that is to say after the cleaning solution or rinsing liquor has been prepared, but only after a certain period of time. In a further preferred embodiment, the shaped bodies are diluted with water at a temperature of about 40 ° C. within a period of up to 10 min, preferably within a period of 0.5 to 9 min, more preferably within 1 to 8 min, particularly preferably within 3 to 8 min at ≥ 70% , preferably to ≥ 80%, particularly preferably to> 90% and particularly preferably to 99 to 100% dissolved.

In this way, after the first cleaning phase or rinsing phase (cleaning the glasses), the user has one for the second cleaning phase or Rinsing phase, which consists, for example, in the cleaning of plates and pots soiled with grease, etc., a detergent composition optimized for this specific cleaning process is available.

According to the invention, the time-delayed dissolution process of the shaped bodies can be controlled using various mechanisms for releasing the active substances. The cleaning or rinsing agent components contained in the molded body, for example surfactant components with strong fat-dissolving power, foam-forming components, etc., are preferably provided with suitable casing, coating and / or matrix materials. The coating or encapsulation while receiving, for example, capsule-like shaped bodies allows a particularly precise and precisely controllable release of the aforementioned components.

According to the invention, the dissolving of the shaped bodies can take place, for example, in a time-controlled manner, in a pH-controlled manner, in a temperature-controlled manner or also in an electrolyte-controlled manner when diluted.

In a further preferred embodiment it is provided that a thickener is added to the liquid phase, so that a stabilization and uniform distribution of the shaped bodies, which particularly preferably have a spherical or capsule-like shape, is ensured in the aforementioned liquid phase. In a preferred embodiment, thickener is added to the liquid phase, so that the moldings “float” in the aforementioned liquid or gel-like phase. This ensures that the user actually produces the cleaning and The necessary proportions of detergent or rinsing agent components are added in the correct ratio A uniform distribution of the shaped bodies or a targeted addition can also be achieved by shaking vigorously immediately before preparing the cleaning solution or rinsing liquor. The moldings are particularly preferably present in the liquid phase at from 0.1 to 30% by weight, preferably from 0.2 to 10% by weight and particularly preferably from 0.5 to 3% by weight, based on the liquid phase ,

In a further preferred embodiment according to the invention, the detergent, in particular hand dishwashing detergent, contains moldings with the same or different detergent or dishwashing component composition, the components from the group comprising silver detergents, corrosion protection agents, hand or skin care agents, special care agents, preferably care agents for ceramics and / or glass, agents for removing special soiling, fat-dissolving substances or mixtures thereof are selected.

Particularly preferred cleaning or rinsing agent components include betaines, fatty alcohol sulfates, fatty alcohol ether sulfates, secondary alkanesulfonates, linear alkylbenzenesulfonates, alkyl alcohol polyglycol ethers, alkyl polygucosides, fatty acid alkanolamides, amine oxides and mixtures thereof. “Fat-dissolving substances” in the sense of the present invention include, in addition to the aforementioned substances, also hydrophobic components. Suitable hydrophobic components include, for example, dialkyl ethers with identical or different C ₄ - to Cu-alkyl radicals, in particular linear dioctyl ethers; hydrocarbons with a boiling range from 100 to 300 ° C. especially 140 to 280 ° C, especially aliphatic hydrocarbons with a boiling range of 145 to 200 ° C, isoparaffins with a boiling range of 200 to 260 ° C; essential oils, especially limonene and the pine oil extracted from pine roots and stumps and also mixtures of these hydrophobic components.

Suitable cleaning and rinsing agent components are, for example, under the trade names Hostapur® SAS 60 (secondary alkane sulfonate from Clariant), Texapon® SPN 70 (fatty alcohol ether sulfate from Henkel KGaA, Düsseldorf), Empinin® KS8 (fatty alcohol ether sulfate from Albright & Wilson GmbH, Frankfurt), Ceraminox ® (amine oxide from Clariant), Sulfopon® 101 (C12-C14 lauryl sulfate from Henkel KGaA, Düsseldorf), Dehyton® (various betaines from Henkel KGaA, Düsseldorf). For example, substances selected from the group consisting of the triazoles, the benzotriazoles, the bisbenzotriazoles, the aminotriazoles, the alkylaminotriazoles and the transition metal salts or complexes can be used as silver protection agents. Benzotriazole and / or alkylaminotriazole are particularly preferably to be used. Zinc compounds can also be used to prevent corrosion on the wash ware. Other cleaning or rinsing agent components are gloss drying additives, cleaning enhancers, antimicrobial agents or disinfectants, antistatic agents, preservatives (eg glutaraldehyde), bleaching systems and dyes, and opacifiers or skin protection agents, as described in EP-A-522 556.

In a particularly preferred embodiment, the detergent, in particular dishwashing detergent, comprises: a) shaped articles with a first detergent component composition comprising at least one component selected from the group consisting of silver detergents, corrosion inhibitors, hand and skin care agents, special care agents, preferably care agents for ceramics and / or glass, and / or means for removing special soiling; and b) moldings with a second detergent component composition comprising at least one fat-dissolving substance, preferably selected from the group consisting of betaines, fatty alcohol sulfates, fatty alcohol ether sulfates, secondary alkane sulfonates, linear alkylbenzenesulfonates, alkyl alcohol polyglycol ethers, alkyl polyglucosides, fatty acid alkanolamides, amine oxides and / or hydrophobic components Shaped body a) contained first detergent component composition when the detergent is diluted with water, preferably before the second detergent component composition contained in shaped body b) is released.

In a preferred embodiment, molded bodies a) and b) differ from one another externally, for example in color. The release mechanism The components contained in molded body a) or b) can be based on the various possible parameters mentioned above. If a suitable shell or matrix material is used, the dissolution of the respective shaped bodies can be controlled almost at any time, pH-controlled, temperature-controlled or even electrolyte strength-controlled.

According to the present invention, it is particularly preferred that the first cleaning or rinsing agent component composition contained in molded body a) is released upon dilution in water before the second cleaning or rinsing agent component composition contained in molded body b), i. H. that the materials or the release mechanism are selected so that the composition in the cleaning solution or rinsing liquor is matched or optimized to the respective cleaning or rinsing phase. The molded body b) preferably contains components which are particularly suitable for removing heavily greasy soiling, for example on plates.

As already stated, the cleaning agent according to the invention, in particular hand dishwashing liquid, in a preferred embodiment comprises a liquid phase and moldings with the same or different composition. The shaped bodies can in principle have any shape, with shapes which can be produced economically and economically being preferred. These include, for example, all shapes which are rotationally symmetrical with respect to at least one axis, for example the spherical shape, elliptical shapes or cylindrical shapes, a capsule in the form of a cylinder closed at both ends being preferred.

In a further particularly preferred embodiment, the matrix, coating and / or coating materials of the shaped bodies are selected such that they dissolve only slowly in water and the incorporated filler components are only incorporated into the application or at a specific point in time or during a specific period of time. Dispense wash liquor.

The coating, coating and / or matrix material suitable according to the invention is preferably water-soluble, or at least water-dispersible, that is to say that the material at least partially dissolves after being introduced into water or at least a dispersion is formed, so that the covering, coating and / or matrix becomes permeable at a predetermined point in time or after a certain period of time and an exchange of substances between the water surrounding the shaped body and the enclosed cleaning agents or detergent components is made possible.

Suitable coating, matrix and / or coating materials include polymers and / or copolymers which are suitable for the dissolution mechanism provided in each case. Suitable materials include alginic acid, alginates, pectins, guar flour, starch, dextrins, gelatin, organic modified natural substances, in particular carboxymethyl cellulose and cellulose ethers, hydroxyethyl and propyl cellulose and the like, polysaccharides, organic fully synthetic substances, in particular polyacrylic and polymethacrylic compounds, Vinyl polymers, in particular polyvinyl alcohols, polycarboxylic acids, polyethers, polyimines, polyamides, polyelectrolytes and, in principle, water-soluble or water-disintegrating polymers. Furthermore, the material from which the covering is made can contain additives which influence the elasticity and water solubility. Suitable plasticizers are, for example, glycol, sorbitol and glycerin.

A time-controlled release of detergent components can be achieved, for example, by changing the pH of the cleaning solution or rinsing liquor. If you consider, for example, the process of manually cleaning dishes, the initial pH value of the washing liquor changes during the washing process. If one assumes that in the first rinsing phase, namely when cleaning the glasses, the object to be rinsed is first cleaned in the washing liquor and then rinsed with fresh water, the pH will drop due to the dilution with pH-neutral water -Values in the washing liquor. The resulting pH value depends on the volume and the detergent component concentration in the washing liquor and on the amount of fresh water added. This pH value change in the rinsing liquor can be used to control the dissolution process of the shaped bodies in a targeted manner. This effect or such a change in pH value is of course also the case with the dilution of cleaning and washing-up liquid concentrates and with diluted ones Observe cleaning agents and can also be used to control the dissolution process of the moldings.

According to the invention, it is preferred to use wrapping, matrix and / or coating materials which experience a change in the physicochemical properties when the pH of the application liquor changes. It is particularly preferred that such substances have an increased solubility in water and / or a decrease in the diffusion density when the pH changes. These substances include basic substances, in particular basic polymers and / or copolymers. The principle of pH-dependent water solubility is usually based on protonation or deprotonation of functional side groups of the polymers. Such polymers with pH-dependent solubility are also known, inter alia, from the pharmaceutical industry, for example in connection with enteric coatings on tablets.

Particularly suitable as pH-sensitive coating, matrix and / or coating materials in the context of the present invention are (co) polymers which preferably have amino groups or aminoalkyl groups. Suitable comonomers are, for example, acrylates, methacrylates, maleinates or derivatives of these compounds. Polymaleimide copolymers, polyacrylamides, polyvinylpyrrolidone copolymers and / or polyurethanes are also suitable.

Furthermore, it is provided according to the invention that the shaped bodies are dissolved under electrolyte control and / or the detergent components contained therein are released due to a change in the electrolyte concentration.

In a particularly preferred embodiment, the cleaning or rinsing agent components are released from the shaped bodies in a temperature-controlled manner. For this purpose, the moldings are produced, for example, from a melt dispersion or emulsion containing the detergent components, the melt suspension or emulsion essentially consisting of a coating substance which has a melting point above 30 ° C. The in the melt suspension Components or emulsion to be incorporated can be at the processing temperature both in solid and in liquid form.

Various requirements are placed on the coating substances, which on the one hand relate to the melting or solidification behavior, but on the other hand also relate to the material properties of the coating in the solidified area at ambient temperature. Since the coating should only release the cleaning or rinsing agent components contained therein in the application liquor and not under thermal stress during transport or storage, the coating substances preferably have a melting point above 30 ° C.

The properties mentioned above are usually fulfilled by so-called waxes. "Waxing" is understood to mean a number of natural or artificially obtained substances which, as a rule, melt above 30 ° C. without decomposition and are relatively low-viscosity and not stringy even a little above the melting point. They have a strongly temperature-dependent consistency and solubility.

The waxes are divided into three groups according to their origin, natural waxes, chemically modified waxes and synthetic waxes.

Natural waxes include, for example, vegetable waxes such as candelilla wax, carnauba wax, japan wax, esparto grass wax, cork wax, guaruma wax, rice germ oil wax, sugar cane wax, ouricury wax, or montan wax, animal waxes such as beeswax, shellac wax, walnut, lanolin (wool wax), or broom wax, mineral wax or ozokerite (earth wax), or petrochemical waxes such as petrolatum, paraffin waxes or micro waxes.

The chemically modified waxes include hard waxes such as montan ester waxes, Sassol waxes or hydrogenated jojoba waxes.

Synthetic waxes are generally understood to mean polyalkylene waxes or polyalkylene glycol waxes. Compounds from other classes of material which meet the stated requirements with regard to the softening point can also be used as covering materials. Suitable synthetic compounds have been found for example, higher esters of phthalic acid, in particular dicyclohexyl phthalate, which is commercially available under the name Unimoll 66 ^® (Bayer AG), proved. Are also suitable Synthetic waxes of lower carboxylic acids and fatty alcohols, such as dimyristyl tartrate, sold under the name Cosmacol ^® ETLP (Condea). Conversely, synthetic or partially synthetic esters from lower alcohols with fatty acids from native sources can also be used. Tegin ^® 90 (Goldschmidt), a glycerol monostearate palmitate, falls into this class of substances. Shellac, for example Shellac-KPS-Dreiring-SP (Kalkhoff GmbH), can also be used as a coating material according to the invention.

The so-called wax alcohols are also included in the waxes in the context of the present invention, for example. Wax alcohols are higher molecular weight, water-insoluble fatty alcohols with usually about 22 to 40 carbon atoms. The wax alcohols occur, for example, in the form of wax esters of higher molecular fatty acids (wax acids) as the main component of many natural waxes. Examples of wax alcohols are lignoceryl alcohol (1-tetracosanol), cetyl alcohol, myristyl alcohol or melissyl alcohol. The coating of the present invention the solid particles coated can optionally also contain wool wax alcohols which are understood to be triterpenoid and steroid alcohols, for example lanolin understood, which is obtainable for example under the trade name Argowax ^® (Pamentier & Co). In the context of the present invention, fatty acid glycerol esters or fatty acid alkanolamides can also be used, at least in part, as a constituent of the casing, but optionally also water-insoluble or only slightly water-soluble polyalkylene glycol compounds.

Further suitable coating substances for the temperature-controlled release of the cleaning or rinsing agent components include polyethylene glycols, polyvinylpyrrolidones, polyethers, carboxymethyl cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose and / or hydroxyethyl propyl cellulose.

Another object of the present invention is the use of the cleaning agent according to the invention for cleaning hard surfaces and / or soft surfaces, preferably as an all-purpose cleaner, bathroom cleaner, floor cleaner, car cleaner, glass cleaner, furniture care agent, furniture cleaner, Facade cleaner, detergent and / or the like and particularly preferably for cleaning dishes. In addition, the present invention relates to a method for cleaning a hard and / or soft surface with an aqueous cleaning liquor, which is characterized in that the cleaning liquor is produced by dissolving or dispersing the cleaning agent according to the invention in water.

The detergent and dishwashing detergent components of the detergent or hand dishwashing detergent according to the present invention include the following substances or groups of substances:

surfactants

The active cleaning phases according to the invention can contain anionic, nonionic, amphoteric or cationic surfactants or surfactant mixtures from one, several or all of these classes of surfactants as surfactant components. The detergents, in particular hand dishwashing detergents, contain surfactants, distributed over the various phases, in amounts, based on the overall formulation, of 5 to 55% by weight, preferably 10 to 30% by weight.

Anionic surfactants

Anionic surfactants according to the present invention can be aliphatic sulfates such as fatty alcohol sulfates, fatty alcohol ether sulfates, dialkyl ether sulfates, monoglyceride sulfates as well as aliphatic and aromatic sulfonates such as alkane sulfonates, olefin sulfonates, ether sulfonates, n-alkyl ether sulfonates, ester sulfonates and lignin sulfonates, lignin sulfonates, lignin sulfonates. Fatty acid cyanamides, sulfosuccinic acid esters, fatty acid isothionates, acylaminoalkanesulfonates (fatty acid taurides), fatty acid sarcosinates, ether carboxylic acids and alkyl (ether) phosphates can also be used in the context of the present invention.

As alk (en) yl sulfates, the alkali and in particular the sodium salts of the sulfuric acid half esters of the C ₂ -C ₈ fatty alcohols, for example from coconut oil alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C10- C ₂ o-oxo alcohols and the half esters of secondary alcohols (secondary alkyl sulfates) of these chain lengths are preferred. Also preferred are alk (en) yl sulfates of the chain length mentioned which contain a synthetic, straight-chain alkyl radical prepared on a petrochemical basis and which have a degradation behavior analogous to that of the adequate compounds based on oleochemical raw materials. With regard to the use of the agent according to the invention as (hand) dishwashing detergent, the C ₂ -C ₆ alkyl sulfates and C ₂ -C ₁₅ alkyl sulfates and C ₄ -Ci ₅ alkyl sulfates are preferred. Suitable secondary alkyl sulfates contain 2- and / or 3-alkyl sulfates and optionally higher homologues (4-, 5-, 6-alkyl sulfates etc.), can be prepared, for example, according to US Pat. Nos. 3,234,258 or 5,075,041 and are commercially available from Shell Oil Company at available under the name DAN ^® , e.g. B. the products mentioned in US Pat. Nos. 5,529,724 and H 1,665 DAN® 214, a C ₁₄ -SAS with 99% 2- and 3-alkyl sulfate, DAN® 216, a C ₁₆ -SAS with 99% 2- and 3-alkyl sulfate, and DAN® 100, a SAS with 62% 2- and 3-alkyl sulfate.

The fatty alcohol ether sulfates are particularly preferred in the context of the present invention. Fatty alcohol ether sulfates are products of sulfation reactions on alkoxylated alcohols. Suitable alkoxylated alcohols are obtained by reacting ethylene oxide with longer-chain alcohols, for example with straight-chain or branched alcohols with chain lengths of C to C ₂ ι such as 2-methyl-branched C ₉ to Cn fatty alcohols. As a rule, a complex mixture of addition products of different degrees of ethoxylation is formed from n moles of ethylene oxide and one mole of alcohol, depending on the reaction conditions. Mixtures of ethylene oxide and propylene oxide can also be used in the ethoxylation reaction. Low-ethoxylated fatty alcohols (0.5 to 4 mol EO, preferably 1 to 2 mol EO) are very particularly preferred in the sense of the present invention.

Particularly preferred within the scope of the present invention further provides the alkane, in particular the secondary alkane sulfonates of unbranched paraffinic hydrocarbons, in particular C-ι ₂ _i ₈ -alkanes, for example by sulfochlorination or sulfoxidation and subsequent hydrolysis or neutralization, be won. A preferred secondary alkane sulfonates is as Hostapur SAS ^® 60, sold by Clariant secondary Ci-Na ₃ -i ₇ alkane.

Other suitable surfactants of the sulfonate type are alkylbenzenesulfonates, olefin sulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates, of the kind obtained, for example, from C ₂ - ₈ mono-olefins with terminal or internal double bonds by sulfonating with gaseous sulfur trioxide and subsequent alkaline or acid hydrolysis of the sulfonation products. Alkylbenzene sulfonates in the context of the teaching according to the invention are alkylbenzenesulfonates having a linear or branched, saturated or unsaturated C _{_6-22} alkyl, preferably C _8-18 alkyl, especially C ₉ _i ₄ alkyl, most preferably Cιo- ₁₃ alkyl radicals. They are used as alkali metal and / or alkaline earth metal salts, in particular sodium, potassium, magnesium and / or calcium salts, and also as ammonium salts or mono-, di- or trialkanolammonium salts, preferably mono-, di- or triethanol and / or -isopropanolammonium salts, especially mono-, di- or

Triethanolammonium salts, but also used as alkylbenzenesulfonic acid together with the corresponding alkali metal or alkaline earth metal hydroxide and / or ammonia or mono-, di- or trialkanolamine. Likewise, the esters of 2-sulfo fatty acids (ester sulfonates), e.g. the 2-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids are suitable.

The anionic surfactants are in the form of their alkali metal and alkaline earth metal salts, in particular sodium, potassium and magnesium salts, as well as ammonium and mono-, di-, tri- or tetraalkylammonium salts and, in the case of the sulfonates, also in the form of the acid, for example dodecylbenzenesulfonic acid, Cι ₀ -Cι ₃ alkylbenzene and / or Cι ₀ -Cι ₄ alkylbenzene used. When sulfonic acid is used, it is usually mixed in situ with one or more corresponding bases, for example alkali metal and alkaline earth metal hydroxides, in particular sodium, potassium and magnesium hydroxide, and ammonia or mono-, di-, tri- or tetraalkylamine, depending on what is to be set pH of the agent partially or completely - neutralized to the aforementioned salts. Because of their foam-suppressing and thickening properties, the cleaning agents according to the invention can also contain soaps, ie alkali metal or ammonium salts of saturated or unsaturated C6-C22 fatty acids.

Nonionic surfactants

Nonionic surfactants in the context of the invention can be alkoxylates, such as polyglycol ethers, fatty alcohol polyglycol ethers, alkylphenol polyglycol ethers, end group-capped polyglycol ethers, mixed ethers and hydroxy mixed ethers and fatty acid polyglycol esters as well as alkyl polyglycosides or nitrogenous surfactants.

Non-ionic surfactants which can preferably be used are the end-capped poly (oxyalkylated) nonionic surfactants of the formula

R ¹ 0 [CH ₂ CH (R ³ ) 0] χ [CH ₂ ] _k CH (OH) [CH ₂ ] _j OR ²

in which R ¹ and R ^{2 are} linear or branched, saturated or unsaturated, aliphatic or aromatic hydrocarbon radicals having 1 to 30 carbon atoms, R3 is H or a methyl, ethyl, n-propyl, isopropyl, n-butyl -, 2-butyl or 2-methyl-2-butyl, x stands for values between 1 and 30, k and j stand for values between 1 and 12, preferably between 1 and 5. If the value x = 2, each R ³ in the above formula can be different. R ¹ and R ² are preferably linear or branched, saturated or unsaturated, aliphatic or aromatic hydrocarbon radicals having 6 to 22 carbon atoms, radicals having 8 to 18 carbon atoms being particularly preferred.
