Definitions
- the present connection relates to a liquid cleaning agent for hard surfaces, in particular for surfaces made of glass and ceramic.
- the cleaning agents for hard surfaces which are customary today are generally aqueous preparations which are either in the form of solutions or suspensions and are offered in liquid or pasty form.
- the main constituents of such agents are surface-active substances, complexing agents for the hardness constituents of water, abrasive substances and organic solvents, the amount of the individual constituents depending on the application can vary within wide limits.
- Detergents which are primarily intended for cleaning glass and ceramic surfaces, are often formulated as solutions of the active substances in a mixture of water and water-soluble organic solvents, primarily lower alcohols and glycol ethers. Examples of such agents can be found in German laid-open specification 22 20 540 and in US Pat. Nos. 3,463,735, 3,882,038 and 3,939,090.
- the cleaning agents In addition to the self-evident requirement for high cleaning performance, there is also the requirement for the simplest and most convenient application of the agents. Often, the desire for the self-acting effect of the funds is expressed, ie the agents are expected to deliver the desired effect even with a single application without further measures. This is before especially when used on smooth surfaces, especially those that can reflect like glass or ceramics, difficult to achieve. As a rule, with today's agents, it is necessary to rinse off the residues of the agents after the actual cleaning cycle or to carefully polish and dry the surfaces in order to avoid visible residues on the smooth surfaces.
- the object of the present invention was to provide an improved agent which is particularly suitable for cleaning glass and ceramic surfaces.
- the invention relates to a liquid cleaning agent for solid surfaces, which contains the following components: 1 to 20% by weight of surfactant from the group consisting of anionic surfactants, nonionic surfactants, amphoteric surfactants and mixtures thereof, 1 to 15% by weight of propylene glycol tert-butyl ether, with the proviso that no more than 50% of this ether can be replaced by other solvents from the group consisting of alcohols with 2 to 3 C atoms, glycol ethers with 4 to 8 C atoms and mixtures thereof can, 0 to 10% by weight solubilizer, 0 to 1% by weight of viscosity regulators, 0 to 5% by weight of complexing agent for alkaline earth ions, 0 to 2% by weight of other auxiliaries and additives and ad 100 wt .-% water.
- surfactant from the group consisting of anionic surfactants, nonionic surfactants, amphoteric surfactants and mixtures thereof
- Another object of the invention is the use of these agents for cleaning hard surfaces, in particular glass and ceramic.
- the agents according to the invention are distinguished by an excellent cleaning action and, in addition, have a particularly pronounced clear drying effect on shiny surfaces. This means that the liquid residues that remain on the surfaces after the cleaning process dry in such a way that practically no solid residues can be seen by the unarmed eye. In this way, the gloss of the surfaces is retained without the need for rinsing or polishing. It is believed that the special properties of the agents are due to the interaction of the propylene glycol tert-butyl ether with the other active ingredients.
- Suitable surfactants for the agents according to the invention are surfactants from the classes of the anionic, the nonionic and also the amphoteric surfactants. Mixtures of anionic and nonionic surfactants are preferably used. The average amount of surfactants is between 1 and 20% by weight, preferably between 2 and 15% by weight and in particular between 3 and 8% by weight, calculated as the sum of all surfactants contained in the compositions.
- Particularly suitable anionic surfactants are alkanesulfonates with 12 to 20 C atoms in the alkyl part, monoalkyl sulfates with 12 to 14 C atoms in the alkyl part and alkyl ether sulfates with 12 to 18 C atoms in the alkyl part and 2 to 6 ethylene oxide units (EO) in the ether part.
- alkanesulfonates with 12 to 20 C atoms in the alkyl part
- monoalkyl sulfates with 12 to 14 C atoms in the alkyl part
- alkyl ether sulfates with 12 to 18 C atoms in the alkyl part and 2 to 6 ethylene oxide units (EO) in the ether part.
- EO ethylene oxide units
- surfactants examples include sodium lauryl ether sulfate with 2 EO, sodium cocoalkyl sulfate and sodium sec-alkane sulfonate with about 15 carbon atoms.
- Alkanesulfonates with 12 to 20 C atoms in the alkyl part and especially alkyl ether sulfates with 12 to 14 C atoms in the alkyl part and 2 to 6 ethylene oxide units (EO) in the ether part have proven to be particularly suitable anionic surfactants.
- the nonionic surfactants used are primarily ethoxylated long-chain alcohols with 12 to 18 carbon atoms in the alkyl part and 5 to 15 ethylene oxide units (EO), ethoxylated alkylphenols with 8 to 10 carbon atoms in the alkyl part and 8 to 14 ethylene oxide units, ethoxylated fatty acid amides with 12 to 18 carbon atoms in the fatty acid part and 2 to 8 ethylene oxide units and long-chain amine oxides with 14 to 20 carbon atoms are used.
- Examples of such surfactants are oleyl-cetyl alcohol with 10 EO, nonylphenol with 10 EO, lauric myristic acid diethanolamide, coconut fatty acid polydiethanolamide and coconut alkyl dimethylamine oxide.
- This component which is particularly important for the invention, is the mono-tertiary butyl ether of 1,2-propylene glycol with the following formula: (CH3) 3-CO-CH2-CH (CH3) -OH
- This ether can be used for the agents of the invention in chemically pure form, but is mostly used in technical quality, which generally has purities of around 95%.
- This solvent is a limited miscible liquid with a boiling point of 151 ° C. In combination with the other ingredients of the agents according to the invention, this ether seems to be responsible for the outstanding clear drying effect of the agents. Its content in the compositions is usually between 1 and 20% by weight, preferably between 3 and 15% by weight.
- propylene glycol tertiary butyl ether is particularly great if it is the only organic solvent contained in the cleaning agents. Its share of the cleaning agents should therefore not be replaced by more than 50%, in particular not more than 30%, by other solvents.
- alcohols with 2 or 3 carbon atoms and other glycol ethers with 4 to 8 carbon atoms are suitable as solvents.
- solubilizers are, for example, short-chain monoalkyl sulfates with 4 to 10 C atoms in the alkyl part, alkylbenzenesulfonates with 1 to 6 C atoms in the alkyl part and urea.
- solubilizers sodium n-octyl sulfate and sodium toluenesulfonate.
- the lower alkylbenzenesulfonates having 1 to 3 carbon atoms in the alkyl chains and urea are preferred.
- the amount of solubilizer in the agents can be up to 10% by weight; as The lower limit of effectiveness is considered to be 0.5% by weight.
- the amount used is preferably between 1 and 5% by weight.
- the cellulose derivatives for example methylhydroxypropyl cellulose and hydroxyethyl cellulose, are particularly preferred.
- the amount of viscosity regulators can be up to 1% by weight; however, sufficient results are often achieved with 0.1% by weight.
- water-soluble complexing agents for alkaline earth ions such as condensed phosphates, polymeric carboxylic acids and low molecular weight organic complexing agents
- low molecular weight water-soluble complexing agents of the type of the polycarboxylic acids, the hydroxycarboxylic acids, the aminopolycarboxylic acids and the polyphosphonic acids are preferably used. These can be used both in the form of the free acids and in the form of water-soluble salts, usually the sodium salts. Nitrilotriacetic acid, citric acid, gluconic acid and their salts are particularly preferred.
- the amount of complexing agents can be up to 8% by weight; amounts between 0.1 and 5% by weight are preferably used.
- the agents according to the invention can contain auxiliaries and additives as are customary in such agents. These include dyes, perfume oils and preservatives.
- the amount of such additives is usually not more than 2% by weight, based on the total agent. The lower limit of use depends on the type of additive and can be up to 0.001% by weight and below, for example, for dyes.
- the amount of auxiliaries and additives is preferably between 0.01 and 1% by weight.
- the agents according to the invention are used in such a way that the agents are first diluted with water, a mixing ratio of 1: 200 to 1:30, in particular 1: 100 to 1:50 (detergent: water) being preferably maintained.
- the surfaces to be treated are then wiped off with this diluted solution, for example with the aid of a sponge or a cloth.
- a further treatment of the surfaces is not necessary because the cleaning solutions dry practically free of fog and do not leave any matting or streaks even on critical, high-gloss surfaces.
- the agent is usually only used for heavy stains. This is followed by the surface cleaning described above with the diluted cleaning solution.
- a cleaning agent according to the invention had the following composition: C16 alkanesulfonate 5.0% by weight Coconut alcohol + 10 EO 3.0% by weight Cumene sulfonate 2.5% by weight Citric acid 0.3% by weight Preservative 0.013% by weight Dye 0.009% by weight Propylene glycol mono-tertiary butyl ether 5.0% by weight Rest of water
- the agent When used in a 5% solution, the agent obtained clean streak-free surfaces with practically no visible residues, even on black tiles and on mirrors without wiping and drying.
- the agent from Example 1 was compared in terms of cleaning effectiveness and clear drying effect with other agents which, with an otherwise identical composition, contained a different water-soluble solvent.
- the cleaning effect of the agents was checked by wiping off a light gray tile which had been soiled with a test soil composed of 60% lime soap, 20% mineral oil and 20% petroleum jelly. In this experiment, too, no rinsing or polishing was carried out. The evaluation was also carried out on a scale between 0 (free of residues) and 10 (strong residues).

Description
Die vorliegende Verbindung betrifft ein flüssiges Reinigungsmittel für harte Oberflächen, insbesondere für Oberflächen aus Glas und Keramik.The present connection relates to a liquid cleaning agent for hard surfaces, in particular for surfaces made of glass and ceramic.
Bei den heute üblichen Reinigugsmitteln für harte Oberflächen handelt es sich in der Regel um wäßrige Zubereitungen, die entweder als Lösungen oder als Suspensionen vorliegen und in flüssiger oder pastöser Form angeboten werden. Hauptbestandteile derartiger Mittel sind oberflächenaktive Substanzen, Komplexbildner für die Härtebestandteile des Wassers, Abrasivstoffe und organische Lösungsmittel, wobei die Menge der einzelnen Bestandteile je nach Anwendungszweck in weiten Grenzen variieren kann. Reinigungsmittel, die vor allem für die Reinigung von Glas- und Keramikoberflächen bestimmt sind, werden häufig als Lösungen der Wirkstoffe in einem Gemisch aus Wasser und in Wasser löslichen organischen Lösungsmitteln, in erster Linie niedere Alkohole und Glykolether, formuliert. Beispiele derartiger Mittel finden sich in der deutschen Offenlegungsschrift 22 20 540 und in den US-Patentschriften 3 463 735. 3 882 038 und 3 939 090.The cleaning agents for hard surfaces which are customary today are generally aqueous preparations which are either in the form of solutions or suspensions and are offered in liquid or pasty form.

Bei der Anwendung der Reinigungsmittel stellt sich neben der selbstverständlichen Forderung nach hoher Reinigungsleistung auch die Forderung nach möglichst einfacher und bequemer Anwendung der Mittel. Häufig wird dabei der Wunsch nach möglichst selbsttätiger Wirkung der Mittel geäußert, d. h., es wird von den Mitteln erwartet, daß sie bereits bei einmaligem Auftrag ohne weitere Maßnahmen die gewünschte Wirkung liefern. Dies ist vor allem bei Anwendung auf glatten Oberflächen, insbesondere solchen, die wie Glas oder Keramik spiegelnd reflektieren können, nur schwer zu verwirklichen. In der Regel ist es bei den heute üblichen Mitteln notwendig, nach dem eigentlichen Reinigungsgang die Rückstände der Mittel abzuspülen oder aber sorgfältig die Oberflächen nachzupolieren und zu trocknen, um sichtbare Rückstände auf den glatten Flächen zu vermeiden.When using the cleaning agents, in addition to the self-evident requirement for high cleaning performance, there is also the requirement for the simplest and most convenient application of the agents. Often, the desire for the self-acting effect of the funds is expressed, ie the agents are expected to deliver the desired effect even with a single application without further measures. This is before especially when used on smooth surfaces, especially those that can reflect like glass or ceramics, difficult to achieve. As a rule, with today's agents, it is necessary to rinse off the residues of the agents after the actual cleaning cycle or to carefully polish and dry the surfaces in order to avoid visible residues on the smooth surfaces.
Aufgabe der vorliegenden Erfindung war es, ein verbessertes Mittel bereitzustellen, das sich insbesondere für die Reinigung von Glas- und Keramikoberflächen eignet.The object of the present invention was to provide an improved agent which is particularly suitable for cleaning glass and ceramic surfaces.

1 bis 20 Gew.-% Tensid aus der Gruppe anionische Tenside, nichtionische Tenside, amphotere Tenside und deren Mischungen,
1 bis 15 Gew.-% Propylenglykoltertiärbutylether, mit der Maßgabe, daß nicht mehr-als 50 % dieses Ethers durch andere Lösungsmittel aus der Gruppe Alkohole mit 2 bis 3 C-Atomen, Glykolether mit 4 bis 8 C-Atomen und deren Mischungen ersetzt sein können,

1 to 20% by weight of surfactant from the group consisting of anionic surfactants, nonionic surfactants, amphoteric surfactants and mixtures thereof,
1 to 15% by weight of propylene glycol tert-butyl ether, with the proviso that no more than 50% of this ether can be replaced by other solvents from the group consisting of alcohols with 2 to 3 C atoms, glycol ethers with 4 to 8 C atoms and mixtures thereof can,
0 to 10% by weight solubilizer,
0 to 1% by weight of viscosity regulators,
0 to 5% by weight of complexing agent for alkaline earth ions,
0 to 2% by weight of other auxiliaries and additives and
ad 100 wt .-% water.
Ein weiterer Gegenstand der Erfindung ist die Verwendung dieser Mittel zur Reinigung von harten Oberflächen, insbesondere aus Glas und Keramik.Another object of the invention is the use of these agents for cleaning hard surfaces, in particular glass and ceramic.
Die erfindungsgemäßen Mittel zeichnen sich durch eine hervorragende Reinigungswirkung aus und besitzen daneben einen besonders ausgeprägten Klartrockeneffekt auf glänzenden Oberflächen. Dies bedeutet, daß die Flüssigkeitsreste, die nach dem Reinigungsvorgang auf den Oberflächen verbleiben, in einer Weise antrocknen, daß für das unbewaffnete Auge praktisch keine festen Rückstände erkennbar sind. Auf diese Weise bleibt der Glanz der Oberflächen erhalten, ohne daß ein Nachspülen oder Nachpolieren notwendig wäre. Es wird vermutet, daß die besonderen Eigenschaften der Mittel auf das Zusammenwirken des Propylenglykoltertiärbutylethers mit den übrigen Wirkstoffen zurückzuführen ist.The agents according to the invention are distinguished by an excellent cleaning action and, in addition, have a particularly pronounced clear drying effect on shiny surfaces. This means that the liquid residues that remain on the surfaces after the cleaning process dry in such a way that practically no solid residues can be seen by the unarmed eye. In this way, the gloss of the surfaces is retained without the need for rinsing or polishing. It is believed that the special properties of the agents are due to the interaction of the propylene glycol tert-butyl ether with the other active ingredients.
Es folgt nun eine Beschreibung der einzelnen Bestandteile der Mittel:The following is a description of the individual components of the funds:
Als oberflächenaktive Substanzen eignen sich für die erfindungsgemäßen Mittel Tenside aus den Klassen der anionischen, der nichtionischen und ferner der amphoteren Tenside. Vorzugsweise werden Mischungen aus anionischen und nichtionischen Tensiden eingesetzt. Die Menge der Tenside beträgt in den Mittel zwischen 1 und 20 Gew.-%, vorzugsweise zwischen 2 und 15 Gew.-% und insbesondere zwischen 3 und 8 Gew.-%, gerechnet als Summe aller in den Mitteln enthaltenen Tenside.Suitable surfactants for the agents according to the invention are surfactants from the classes of the anionic, the nonionic and also the amphoteric surfactants. Mixtures of anionic and nonionic surfactants are preferably used. The average amount of surfactants is between 1 and 20% by weight, preferably between 2 and 15% by weight and in particular between 3 and 8% by weight, calculated as the sum of all surfactants contained in the compositions.
Als anionische Tenside eignen sich insbesondere Alkansulfonate mit 12 bis 20 C-Atomen im Alkylteil, Monoalkylsulfate mit 12 bis 14 C-Atomen im Alkylteil und Alkylethersulfate mit 12 bis 18 C-Atomen im Alkylteil und 2 bis 6 Ethylenoxideinheiten (EO) im Etherteil.Particularly suitable anionic surfactants are alkanesulfonates with 12 to 20 C atoms in the alkyl part, monoalkyl sulfates with 12 to 14 C atoms in the alkyl part and alkyl ether sulfates with 12 to 18 C atoms in the alkyl part and 2 to 6 ethylene oxide units (EO) in the ether part.
Beispiele derartiger Tenside sind Natriumlaurylethersulfat mit 2 EO, Natriumkokosalkylsulfat und Natrium-sec.-Alkansulfonat mit ca. 15 C-Atomen.Examples of such surfactants are sodium lauryl ether sulfate with 2 EO, sodium cocoalkyl sulfate and sodium sec-alkane sulfonate with about 15 carbon atoms.
Als besonders geeignete anionische Tenside haben sich Alkansulfonate mit 12 bis 20 C-Atomen im Alkylteil und vor allem Alkylethersulfate mit 12 bis 14 C-Atomen im Alkylteil und 2 bis 6 Ethylenoxideinheiten (EO) im Etherteil erwiesen.Alkanesulfonates with 12 to 20 C atoms in the alkyl part and especially alkyl ether sulfates with 12 to 14 C atoms in the alkyl part and 2 to 6 ethylene oxide units (EO) in the ether part have proven to be particularly suitable anionic surfactants.
Als nichtionische Tenside werden in erster Linie ethoxylierte langkettige Alkohole mit 12 bis 18 C-Atomen im Alkylteil und 5 bis 15 Ethylenoxideinheiten (EO), ethoxylierte Alkylphenole mit 8 bis 10 C-Atomen im Alkylteil und 8 bis 14 Ethylenoxideinheiten, ethoxylierte Fettsäureamide mit 12 bis 18 C-Atomen im Fettsäureteil und 2 bis 8 Ethylenoxideinheiten sowie langkettige Aminoxide mit 14 bis 20 C-Atomen verwendet. Beispiele derartiger Tenside sind Oleyl-Cetyl-Alkohol mit 10 EO, Nonylphenol mit 10 EO, Laurinmyristinsäurediethanolamid, Kokosfettsäurepolydiethanolamid und Kokosalkyldimethylaminoxid.The nonionic surfactants used are primarily ethoxylated long-chain alcohols with 12 to 18 carbon atoms in the alkyl part and 5 to 15 ethylene oxide units (EO), ethoxylated alkylphenols with 8 to 10 carbon atoms in the alkyl part and 8 to 14 ethylene oxide units, ethoxylated fatty acid amides with 12 to 18 carbon atoms in the fatty acid part and 2 to 8 ethylene oxide units and long-chain amine oxides with 14 to 20 carbon atoms are used. Examples of such surfactants are oleyl-cetyl alcohol with 10 EO, nonylphenol with 10 EO, lauric myristic acid diethanolamide, coconut fatty acid polydiethanolamide and coconut alkyl dimethylamine oxide.
Als besonders geeignete nichtionische Tenside haben sich die Additionsprodukte aus Ethylenoxid und Fettalkoholen, Alkylphenolen sowie Fettsäureamiden erwiesen.The addition products of ethylene oxide and fatty alcohols, alkylphenols and fatty acid amides have proven to be particularly suitable nonionic surfactants.
Bei diesem für die Erfindung besonders wesentlichen Bestandteil handelt es sich um den Monotertiärbutylether des 1,2-Propylenglykols mit folgender Formel:
(CH₃)₃-C-O-CH₂-CH(CH₃)-OH
This component, which is particularly important for the invention, is the mono-tertiary butyl ether of 1,2-propylene glycol with the following formula:
(CH₃) ₃-CO-CH₂-CH (CH₃) -OH
Dieser Ether kann für die Mittel der Erfindung in chemisch reiner Form eingesetzt werden, wird jedoch meist in technischer Qualität verwendet, die im allgemeinen Reinheiten um 95 % aufweist. Es handelt sich bei diesem Lösungsmittel um eine begrenzt mit Wasser mischbare Flüssigkeit, die einen Siedepunkt von 151 °C aufweist. Im Zusammenwirken mit den übrigen Inhaltsstoffen der erfindungsgemäßen Mittel scheint dieser Ether für den überragenden Klartrockeneffekt der Mittel verantwortlich zu sein. Sein Gehalt in den Mitteln liegt üblicherweise zwischen 1 und 20 Gew.-%, vorzugsweise zwischen 3 und 15 Gew.-%.This ether can be used for the agents of the invention in chemically pure form, but is mostly used in technical quality, which generally has purities of around 95%. This solvent is a limited miscible liquid with a boiling point of 151 ° C. In combination with the other ingredients of the agents according to the invention, this ether seems to be responsible for the outstanding clear drying effect of the agents. Its content in the compositions is usually between 1 and 20% by weight, preferably between 3 and 15% by weight.
Der Effekt des Propylenglykol-tertiär-butylethers ist besonders groß, wenn er als einziges organisches Lösungsmittel in den Reinigungsmitteln enthalten ist. Sein Anteil an den Reinigungsmitteln sollte daher zu nicht mehr als 50 %, insbesondere nicht mehr als 30 % durch andere Lösungsmittel ersetzt sein. Dabei kommen als Lösungsmittel neben diesem Ether Alkohole mit 2 oder 3 C-Atomen und andere Glykolether mit 4 bis 8 C-Atomen in Betracht.The effect of the propylene glycol tertiary butyl ether is particularly great if it is the only organic solvent contained in the cleaning agents. Its share of the cleaning agents should therefore not be replaced by more than 50%, in particular not more than 30%, by other solvents. In addition to this ether, alcohols with 2 or 3 carbon atoms and other glycol ethers with 4 to 8 carbon atoms are suitable as solvents.
Je nach Art und Menge der verwendeten Inhaltsstoffe kann es, wenn die Mittel das Aussehen einer klaren Lösung haben sollen, notwendig sein, Lösevermittler einzusetzen. Als Lösevermittler eignen sich beispielsweise kurzkettige Monoalkylsulfate mit 4 bis 10 C-Atomen im Alkylteil, Alkylbenzolsulfonate mit 1 bis 6 C-Atomen im Alkylteil und Harnstoff. Beispiele derartiger Lösevermittler sind Natrium-n-octylsulfat und Natriumtoluolsulfonat.Depending on the type and amount of the ingredients used, it may be necessary to use solubilizers if the agents are to have the appearance of a clear solution. Suitable solubilizers are, for example, short-chain monoalkyl sulfates with 4 to 10 C atoms in the alkyl part, alkylbenzenesulfonates with 1 to 6 C atoms in the alkyl part and urea. Examples of such solubilizers are sodium n-octyl sulfate and sodium toluenesulfonate.
Bevorzugt werden die niederen Alkylbenzolsulfonate mit 1 bis 3 C-Atomen in den Alkylketten und Harnstoff. Die Menge an Lösevermittler in den Mitteln kann bis zu 10 Gew.-% betragen; als Untergrenze der Wirksamkeit werden 0,5 Gew.-% angesehen. Vorzugsweise liegt die Einsatzmenge zwischen 1 und 5 Gew.-%.The lower alkylbenzenesulfonates having 1 to 3 carbon atoms in the alkyl chains and urea are preferred. The amount of solubilizer in the agents can be up to 10% by weight; as The lower limit of effectiveness is considered to be 0.5% by weight. The amount used is preferably between 1 and 5% by weight.
In vielen Fällen kann es notwendig sein, die Viskosität der erfindungsgemäßen Mittel auf die Anwendung möglichst optimal einzustellen. Dies kann durch geeignete Wahl der Komponenten aber auch durch Zusatz von Viskositätsregulatoren erreicht werden. Für die erfindungsgemäßen Mittel eignen sich vorzugsweise hydrophile synthetische und modifizierte natürliche Polymere.In many cases it may be necessary to optimally adjust the viscosity of the agents according to the invention to the application. This can be achieved by a suitable choice of components, but also by adding viscosity regulators. Hydrophilic synthetic and modified natural polymers are preferably suitable for the agents according to the invention.
Von diesen werden wiederum die Cellulosederivate, beispielsweise Methylhydroxypropylcellulose und Hydroxyethylcellulose besonders bevorzugt. Die Menge an Viskositätsregulatoren kann bis zu 1 Gew.-% betragen; häufig werden jedoch bereits mit 0,1 Gew.-% ausreichende Ergebnisse erzielt.Of these, the cellulose derivatives, for example methylhydroxypropyl cellulose and hydroxyethyl cellulose, are particularly preferred. The amount of viscosity regulators can be up to 1% by weight; however, sufficient results are often achieved with 0.1% by weight.
Grundsätzlich eignen sich für die Mittel der Erfindung alle bekannten wasserlöslichen Komplexbildner für Erdalkaiiionen, wie kondensierte Phosphate, polymere Carbonsäuren und niedermolekulare organische Komplexbildner. Vorzugsweise werden niedermolekulare wasserlösliche Komplexbildner vom Typ der Polycarbonsäuren, der Hydroxycarbonsäuren, der Aminopolycarbonsäuren und der Polyphosphonsäuren verwendet. Diese können sowohl in Form der freien Säuren als auch in Form wasserlöslicher Salze, meist der Natriumsalze, eingesetzt werden. Besonders bevorzugt werden Nitrilotriessigsäure, Citronensäure, Gluconsäure und deren Salze. Die Menge an Komplexbildnern kann in den Mitteln bis zu 8 Gew.-% betragen; vorzugsweise werden Mengen zwischen 0,1 und 5 Gew.-% eingesetzt.In principle, all known water-soluble complexing agents for alkaline earth ions, such as condensed phosphates, polymeric carboxylic acids and low molecular weight organic complexing agents, are suitable for the agents of the invention. Low molecular weight water-soluble complexing agents of the type of the polycarboxylic acids, the hydroxycarboxylic acids, the aminopolycarboxylic acids and the polyphosphonic acids are preferably used. These can be used both in the form of the free acids and in the form of water-soluble salts, usually the sodium salts. Nitrilotriacetic acid, citric acid, gluconic acid and their salts are particularly preferred. The amount of complexing agents can be up to 8% by weight; amounts between 0.1 and 5% by weight are preferably used.
Neben den bisher genannten Wirksubstanzen können die erfindungsgemäßen Mittel Hilfs- und Zusatzstoffe enthalten, wie sie in derartigen Mitteln üblich sind. Dazu zählen insbesondere Farbstoffe, Parfümöle und Konservierungsmittel. Die Menge an derartigen Zusätzen liegt üblicherweise nicht über 2 Gew.-%, bezogen auf das gesamte Mittel. Die Untergrenze des Einsatzes hängt von der Art des Zusatzstoffes ab und kann beispielsweise bei Farbstoffen bis zu 0,001 Gew.-% und darunter betragen. Vorzugsweise liegt die Menge an Hilfs- und Zusatzstoffen zwischen 0,01 und 1 Gew.-%.In addition to the active substances mentioned above, the agents according to the invention can contain auxiliaries and additives as are customary in such agents. These include dyes, perfume oils and preservatives. The amount of such additives is usually not more than 2% by weight, based on the total agent. The lower limit of use depends on the type of additive and can be up to 0.001% by weight and below, for example, for dyes. The amount of auxiliaries and additives is preferably between 0.01 and 1% by weight.
Die Anwendung der erfindungsgemäßen Mittel geschieht in der Weise, daß man zunächst die Mittel mit Wasser verdünnt, wobei vorzugsweise ein Mischungsverhältnis von 1 : 200 bis 1 : 30, insbesondere 1 : 100 bis 1 : 50, (Reinigungsmittel : Wasser) eingehalten wird. Mit dieser verdünnten Lösung werden dann die zu behandelnden Oberflächen, beispielsweise mit Hilfe eines Schwammes oder eines Tuches abgewischt. Eine weitere Behandlung der Oberflächen ist nicht notwendig, da die Reinigerlösungen praktisch schleierfrei auftrocknen und selbst auf kritischen, hoch glänzenden Oberflächen keine Mattierung oder Streifen hinterlassen. In höherer Konzentration oder unverdünnt wird das Mittel in der Regel nur bei starken fleckförmigen Anschmutzungen eingesetzt. Im Anschluß daran erfolgt die oben beschriebene Flächenreinigung mit der verdünnten Reinigerlösung.The agents according to the invention are used in such a way that the agents are first diluted with water, a mixing ratio of 1: 200 to 1:30, in particular 1: 100 to 1:50 (detergent: water) being preferably maintained. The surfaces to be treated are then wiped off with this diluted solution, for example with the aid of a sponge or a cloth. A further treatment of the surfaces is not necessary because the cleaning solutions dry practically free of fog and do not leave any matting or streaks even on critical, high-gloss surfaces. In higher concentrations or undiluted, the agent is usually only used for heavy stains. This is followed by the surface cleaning described above with the diluted cleaning solution.
Ein erfindungsgemäßes Reinigungsmittel hatte folgende Zusammensetzung:
C₁₆-Alkansulfonat 5,0 Gew.-%
Kokosalkohol + 10 EO 3,0 Gew.-%
Cumolsulfonat 2,5 Gew.-%
Citronensäure 0,3 Gew.-%
Konservierungsmittel 0,013 Gew.-%
Farbstoff 0,009 Gew.-%
Propylenglykolmono-tertiärbutylether 5,0 Gew.-%
Rest WasserA cleaning agent according to the invention had the following composition:
C₁₆ alkanesulfonate 5.0% by weight
Coconut alcohol + 10 EO 3.0% by weight
Cumene sulfonate 2.5% by weight
Citric acid 0.3% by weight
Preservative 0.013% by weight
Dye 0.009% by weight
Propylene glycol mono-tertiary butyl ether 5.0% by weight
Rest of water
Es wurde durch Auflösen der Einzelkomponenten in Wasser hergestellt.It was made by dissolving the individual components in water.
Bei Anwendung in 5 %iger Lösung wurden mit dem Mittel selbst auf schwarzen Kacheln und auf Spiegeln ohne Nachwischen und Nachtrocknen saubere streifenfreie Oberflächen erhalten, die praktisch keine sichtbaren Rückstände aufwiesen.When used in a 5% solution, the agent obtained clean streak-free surfaces with practically no visible residues, even on black tiles and on mirrors without wiping and drying.
Wurde anstelle des Propylenglykol-tertitiär-butylethers ein 1 : 1- Gemisch aus Propylenglykol-tertitär-butylether und Diethylenglykolmonobutylether eingesetzt, so wurde nur eine geringfügig schlechtere Wirksamkeit beobachtet.If a 1: 1 mixture of propylene glycol tertiary butyl ether and diethylene glycol monobutyl ether was used instead of the propylene glycol tertiary butyl ether, only a slightly poorer activity was observed.
Das Mittel aus Beispiel 1 wurde hinsichtlich Reinigungswirksamkeit und Klartrockeneffekt mit anderen Mitteln verglichen, die bei ansonsten gleicher Zusammensetzung ein anderes wasserlösliches Lösungsmittel enthielten. Das Verfahren zur Prüfung des Klartrockeneffektes bestand darin, 100 ml einer 5 %igen Lösung des Reinigungsmittels über eine schräggestellte schwarze Kachel ablaufen zu lassen und nach dem Abtrocknen der Flüssigkeit das Aussehen der Kachel zu begutachten. Dabei reichte der Bewertungsmaßstab von 0 (= völlig unveränderter Glanz) bis 10 (stark mattiert). Die Reinigungswirkung der Mittel wurde durch Abwischen einer hellgrauen Kachel, die mit einer Testanschmutzung aus 60 % Kalkseife, 20 % Mineralöl und 20 % Vaseline angeschmutzt war, geprüft. Auch bei diesem Versuch wurde nicht nachgespült oder poliert. Die Bewertung erfolgte ebenfalls mit einer Skala zwischen 0 (frei von Rückständen) bis 10 (starke Rückstände). Die nachfolgende Tabelle zeigt die Ergebnisse:
Aus den Ergebnissen wird deutlich, daß Mittel auf Basis von Propylenglykol-tertiär-butylether den übrigen Mitteln auf Basis heute üblicher Lösungsmittel deutlich überlegen sind.It is clear from the results that agents based on propylene glycol tertiary butyl ether are clearly superior to the other agents based on solvents which are customary today.
Ähnlich gute Ergebnisse wurden mit Mitteln erzielt, die anstelle von Alkansulfonat das Natriumsalz eines Kokosalkohol + 3,7 EO-Sulfats oder anstelle des Fettalkoholethoxylats Kokosfettsäurepolydiethanolamid enthielten.Similarly good results were obtained with agents which contained the sodium salt of a coconut alcohol + 3.7 EO sulfate instead of alkane sulfonate or coconut fatty acid polydiethanolamide instead of the fatty alcohol ethoxylate.
