Abstract

1. A care composition for the cleaning of sensitive surfaces, composed of an aqueous and a non-aqueous liquid phase, wherein the non-aqueous phase is 1,1,2-trichloro-1,2,2-trifluoroethane (FKW 113), the composition contains at least one surfactant, is free from wax and contains a liquid, water-soluble silicone oil.

Description

Die vorliegende Erfindung betrifft ein Pflegemittel für Kunststoff-Oberflächen, das neben einer wäßrigen Phase noch eine organische Phase enthält die im wesentlichen aus FKW 113 (= 1,1,2-Trichlor-1,2,2-trifluorethan) besteht Dieses Mittel eignet sich ferner zur Reinigung und Pflege anderer empfindlicher Oberflächen, z.B. aus Holz, lackiertem Metall oder Glas.The present invention relates to a cleaning agent for plastic surfaces which, in addition to an aqueous phase, also contains an organic phase which essentially consists of HFC 1 13 (= 1,1,2-trichloro-1,2,2-trifluoroethane). This agent is suitable also for cleaning and care of other sensitive surfaces, such as wood, painted metal or glass.

Für die Pflege von Gehäuseplatten oder Frontplatten von Geräten, insbesondere elektrischen oder elektronischen Einheiten, mit Kunststoff-Oberflächen oder anderen Sichtflächen, z.B. lackierten oder bedruckten Platten, sind eine Reihe von Reinigungsmitteln auf dem Markt verfügbar, vorwiegend in Form von Flüssigkeiten, Emulsionen, Suspensionen oder Pasten. Diese Produkte sind in vielen Fällen zwar wirksam, jedoch werden bei ihrem Gebrauch die zu reinigenden Kunststoffplatten durch Spannungsrißkorrosion unansehnlich oder durch abrasive Beanspruchung aufgerauht oder die Geräte werden durch Anlösen ihrer Lackoberflächen oder Beschriftungen geschädigt.For the maintenance of housing panels or front panels of devices, in particular electrical or electronic units, with plastic surfaces or other visible surfaces, e.g. lacquered or printed plates, a number of cleaning agents are available on the market, mainly in the form of liquids, emulsions, suspensions or pastes. Although these products are effective in many cases, the plastic sheets to be cleaned are unsightly due to stress corrosion cracking or roughened when they are used, or the devices are damaged by loosening their paint surfaces or lettering.

Es bestand daher die Aufgabe, ein Mittel zu schaffen, das die genannten Nachteile handelsüblicher Mittel vermeidet Es wurde nun ein Pflegemittel zur Behandlung von Kunststoffoberflächen geschaffen, das aus einer wäßrigen und einer nicht-wäßrigen flüssigen Phase besteht das dadurch gekennzeichnet ist daß es frei ist von Wachs, die nicht-wäßrige Phase im wesentlichen aus FKW 113 besteht das Mittel mindestens ein Tensid und mindestens ein wasserlösliches Silikonöl enthättIt was therefore the task of creating an agent which avoids the disadvantages of commercially available agents. A care agent for the treatment of plastic surfaces has now been created, which consists of an aqueous and a non-aqueous liquid phase which is characterized in that it is free of Wax, the non-aqueous phase consisting essentially of HFC 113, contains at least one surfactant and at least one water-soluble silicone oil

Das Mittel kann darüber hinaus noch weitere Bestandteile in kleinen Anteilen enthalten, die die Pflegeeigenschaften nicht beeinträchtigen, beispielsweise Farbstoffe oder Parfüm-Öle. Auch die Gegenwart von wasserunlöslichen organischen Lösemitteln ist möglich. Bevorzugt ist jedoch Abwesenheit solcher Lösemittel (Produkte die bei Normaldruck und Zimmertemperatur gasförmig sind, zB. Difluordichlormethan oder Tetrafluordichlorethan gelten in diesem Zusammenhang nicht als Lösemittel).The agent can also contain other ingredients in small proportions that do not affect the care properties, such as dyes or perfume oils. The presence of water-insoluble organic solvents is also possible. However, preference is given to the absence of such solvents (products which are gaseous at atmospheric pressure and room temperature, for example difluorodichloromethane or tetrafluorodichloroethane are not considered solvents in this context).

Es ist beverzugt, wenn die eingesetzten Tenside besonders wirksam Emulgatoren für die beiden flüssigen Phasen darstellen. Bevorzugt sind ionogene Tenside, insbesondere anionaktive Tenside. Besonders bewährt als Tenside haben sich Verbindungen mit einer organisch gebundenden Sulfatgruppe oder Sulfonatgruppe. Der Anteil der Tenside muß dafür ausreichen, daß das erfindungsgemäße Mittel beim Schütteln in eine Emulsion übergeht Im allgemeinen reichen Gehalte von 1 bis 10 Gew.-%, insbesondere 2 bis 8 Gew.-% Tensid hierfür aus. Es können aber auch höhere Konzentrationen erforderlich sein.It is delayed if the surfactants used are particularly effective emulsifiers for the two liquid phases. Ionic surfactants, in particular anionic surfactants, are preferred. Compounds with an organically bound sulfate group or sulfonate group have proven particularly useful as surfactants. The proportion of surfactants must be sufficient for the agent according to the invention to be converted into an emulsion when shaken. In general, contents of 1 to 10% by weight, in particular 2 to 8% by weight, of surfactant are sufficient for this. However, higher concentrations may also be required.

Als Tenside mit Sulfatgruppe seien angeführt Salze von Schwefelsäurehalbestem von Fettalkoholen mit C, bis C20-Alkyl-resten, die gegebenenfalls bis zu 30 Alkylenoxid-Einheiten der Formel -OC2H4-oder -OC3H6-im Molekül enthalten können. Bevorzugt sind 0-10, insbesondere 0-5 Alkylenoxid-Einheiten. Besonders bevorzugt sind Salze von Schwefelsäurehalbestem mit einer C10-C12-Alkylgruppe, insbesondere deren Triäthanolamin-Salze, vorzugsweise ohne Alkyfenoxid-Einheit.Examples of surfactants with a sulfate group are salts of sulfuric acid semiesters of fatty alcohols with C 1 -C 20 -alkyl radicals, which may optionally contain up to 30 alkylene oxide units of the formula -OC 2 H 4 or -OC 3 H 6 in the molecule. 0-10, in particular 0-5, alkylene oxide units are preferred. Salts of sulfuric acid semiesters with a C 10 -C 12 alkyl group, in particular their triethanolamine salts, preferably without an alkylene oxide unit, are particularly preferred.

Als Vertreter der Verbindungen mit Sulfonatgruppe seien genannt Alkansulfonate mit 6 bis 20 Kohlenstoffatomen im Alkylrest Arylsulfonate, insbesondere Phenyl sulfonate und Alkylphenylsulfonate mit 1 bis 10 C-Atomen im AlkylrestRepresentatives of the compounds having a sulfonate group include alkanesulfonates having 6 to 20 carbon atoms in the alkyl radical, aryl sulfonates, in particular phenyl sulfonates and alkylphenylsulfonates having 1 to 10 carbon atoms in the alkyl radical

Viele der einsetzbaren wasserlöslichen Silikonöle weisen antistatische Eigenschaften auf. Bevorzugt sind flüssige Siloxan-Glykol-Blockcopolymerisate, insbesondere Polydimethylsiloxan-Polyoxyalkylenblockpolymere wie das Siliconöl L03 der Wacker-Chemie GmbH oder Surfactant 190 und 193 der DOW CORNING.Many of the water-soluble silicone oils that can be used have antistatic properties. Liquid siloxane-glycol block copolymers, in particular polydimethylsiloxane Polyoxyalkylenblockpolymere are preferred as the silicone oil L03 of Wacker-Chemie GmbH, or surfactant 190 and 1 93 of the DOW CORNING.

Solche Blockcopolymerisate werden z.B. in der DE-OS 2135536, US-PS 3402192 oder US-PS 3713851 angegeben. Die Chemie der flüssigen Silikone wird behandelt in KirkOthmer, Encyclopedia of Chemical Technology Vol. 20, 3rd Ed. p 922-962.Such block copolymers are US-PS indicated for example in DE-OS 2135536, 3 4 02192 or US-PS 3713851st The chemistry of liquid silicones is discussed in KirkOthmer, Encyclopedia of Chemical Technology Vol. 20, 3rd Ed. p 922-962.

Das Gewichtsverhältnis von wäßriger Phase zu nicht-wäßriger flüssiger Phase kann in weiten Grenzen - schwanken. Bewährt haben sich Verhältnisse von 10 : 90 bis 90 : 10, vorzugsweise 25 : 75 bis 75 : 25, insbesondere 40 : 60 bis 60 : 40.The weight ratio of aqueous phase to non-aqueous liquid phase can vary within wide limits. Ratios of 10:90 to 90:10, preferably 25:75 to 75:25, in particular 40:60 to 60:40, have proven successful.

Bei Zusatz eines zweiten Silikonöls, das nicht in Wasser, wohl aber in FKW 113 löslich ist, wird der Glanz der gereinigten Oberflächen erheblich verstärkt. Einsetzbar sind hierfür insbesondere flüssige Polysiloxane wie z.B.When a second silicone oil is added, which is not soluble in water, but is soluble in HFC 113, the shine of the cleaned surfaces is considerably increased. Liquid polysiloxanes such as e.g.

Arylalkyl-Polysiloxane, insbesondere Phenyfalkyl-Polysiloxane, vorzugsweise Phenylmethyl-Polysiloxane oder flüssige Alkyl-methyl-polysiloxane, insbesondere Dimethylpolysiloxane. Die gleichzeitige Verwendung von zwei Silikonölen mit unterschiedlichen Löslichkeitseigenschaften ist daher bevorzugt.Arylalkyl polysiloxanes, especially phenyfalkyl polysiloxanes, preferably phenylmethyl polysiloxanes or liquid alkylmethyl polysiloxanes, especially dimethylpolysiloxanes. The simultaneous use of two silicone oils with different solubility properties is therefore preferred.

Es ist vorteilhaft wenn das erfindungsgemäße wachsfreie Pflegemittel frei ist von Fluortensiden.It is advantageous if the wax-free care agent according to the invention is free of fluorosurfactants.

Das erfindungsgemäße Pflegemittel vermeidet die Nachteile vieler herkömmlicher Reinigungsmittel und bietet außerdem eine Reihe von Vorzügen:

  • 1. Die Pflegemittel besitzen ein sehr hohes Reinigungspotential gegenüber allen Verschmutzungen, die sich im Normalgebrauch auf den Oberflächen von elektrorischen Geräten (z.B. Phono-und Video-oder EDV-Geräten) bilden.
  • 2. Die erfindungsgemäßen Pflegemittel versehen die behandelten Oberflächen in den meisten Fällen mit einem stark antistatisch wirkenden Film, der die Anziehung von Staubpartikeln lange Zeit verhindert
  • 3. Oberflächen, die mit dem erfindungsgemäßen Mittel behandelt wurden, zeigen nach dem Abwischen mit einem weichen Tuch einen angenehm erscheinenden Glanz. Farbtiefe und Farbsättigung werden deutlich erhöht
  • 4. Die erfindungsgemäßen Pflegemittel greifen blanke Kunststoff-Oberflächen, aber auch lackierte oder bedruckte Metall-oder Holzoberflächen praktisch nicht an, da aggressive Lösemittel, wie Ketone, Ester oder Chlorkohlenwasserstoffe, fehlen. Aus diesem Grund ist auch der Zusatz weiterer organischer Lösemittel nicht zweckmäßig. Die Mittel lösen aber Schmutzfilme sowohl hydrophiler als auch lipophiler Natur
  • 5. Da die erfindungsgemäßen Mittel frei sind von ungelösten Feststoffen, wirken sie auf kratzempfindlichen Oberflächen nicht abrasiv oder aufrauhend. Sie hinterlassen auf den behandelten Flächen keine störenden Rückstände, die eine Neuverschmutzung fördern könnten.
  • 6. Wegen ihres Gehaltes an antiadhäsiven Substanzen, die in geringster Konzentration auf den behandelten Oberflächen zurückbleiben, vermindern die erfindungsgemäßen Mittel eine Neuverschmutzung erheblich, da Schmutzpartikel nicht haften bleiben.
The care product according to the invention avoids the disadvantages of many conventional cleaning products and also offers a number of advantages:
  • 1. The care products have a very high cleaning potential in relation to all soiling that forms on the surfaces of electrical devices (for example phono and video or EDP devices) in normal use.
  • 2. The care products according to the invention in most cases provide the treated surfaces with a strongly antistatic film which prevents the attraction of dust particles for a long time
  • 3. Surfaces which have been treated with the agent according to the invention, after wiping with a soft cloth, have a pleasant-looking sheen. Color depth and saturation are significantly increased
  • 4. The care products according to the invention practically do not attack bare plastic surfaces, but also lacquered or printed metal or wood surfaces, since aggressive solvents, such as ketones, esters or chlorinated hydrocarbons, are missing. For this reason, the addition of further organic solvents is also not advisable. However, the agents loosen dirt films of both hydrophilic and lipophilic nature
  • 5. Since the agents according to the invention are free from undissolved solids, they do not have an abrasive or roughening effect on scratch-sensitive surfaces. They do not leave any annoying residues on the treated areas that could promote new pollution.
  • 6. Because of their content of anti-adhesive substances which remain in the lowest concentration on the treated surfaces, the inventive ones decrease Means a considerable amount of new pollution because dirt particles do not stick.

Die erfindungsgemäßen Pflegemittel kommen wegen der beschriebenen Eigenschaften einem akuten Bedürfnis entgegen, insbesondere in den Bereichen der Unterhaltungselektronik und Datenverarbeitung, aber auch im Haushaltssektor (bei der Pflege von Möbeln, Fensterrahmen, Türen) sowie bei der Fahrzeugpflege.The care products according to the invention meet an acute need because of the properties described, in particular in the fields of consumer electronics and data processing, but also in the household sector (in the care of furniture, window frames, doors) and in vehicle care.

Auf Leder-und Kunstleder-Oberflächen sind sie vorteilhaft verwendbar. Auch die Reinigung von Metalloberflächen ist möglich, obwohl dabei der antistatische Effekt der erfindungsgemäßen Mittel nicht vonnöten ist. Diese Mittel sind nicht bestimmt für die Reinigung der Rillen von Schallplatten.They can be used advantageously on leather and synthetic leather surfaces. It is also possible to clean metal surfaces, although the antistatic effect of the agents according to the invention is not required. These agents are not intended for cleaning the grooves of records.

Die erfindungsgemäßen Mittel können unterschiedlich angewandt werden. Bei Flüssigkeitsgemischen ohne Aerosol-Treibgas läßt sich durch kurzes Schütteln des PflegemittelBehälters die nicht-wäßrige in der wäßrigen Phase emulgieren. Die erhaltene Emulsion wird zweckmäßigerweise auf ein Tuch aus Textilien oder auf ein Papiervlies aufgebracht und die zu pflegende Fläche damit abgewischt, abgerieben und gegebenenfalls poliert.The agents according to the invention can be used in different ways. In the case of liquid mixtures without aerosol propellant, the non-aqueous phase can be emulsified in the aqueous phase by briefly shaking the care agent container. The emulsion obtained is expediently applied to a cloth made of textiles or to a paper fleece and the surface to be cared for is wiped, rubbed and optionally polished.

In solchen Fällen, in denen die Gefahr besteht, daß ein flüssiges Reinigungsmittel durch Fugen in das Innere eines Gerätegehäuses fließt und dort Funktionsstörungen verursacht, ist es vorteilhaft, das Mittel in Form eines Schaums einzusetzen. Dieser Schaum soll so steif und stabil sein, daß er nicht in Fugen oder Ritzen der zu behandelnden Oberflächen eindringen kann. Um für diese Zwecke ein Schaumaerosol zu bereiten, füllt man das erfindungsgemäße Pflegemittel in übliche Aerosoldosen und drückt in diese nach dem Verschließen mit geeigneten Aerosolventilen ein Aerosoltreibgas oder ein Aerosoltreibgasgemisch ein. Verwendbar sind vornehmlich druckverflüssigte Treibgase, wie Dichlordifluormethan (FKW 12) und/oder Dichlortetrafluorethan (FKW 114) oder komprimierte Treibgase, die in der AerosolTechnik benutzt werden, wie Kohlendioxid. Der Bedarf an Treibgas zur Erzeugung eines stabilen Schaums bei Betätigung des Aerosolventils (nach Schütteln der Aerosoldose) liegt in der Größenordnung von 2 bis 30 Masse-%, bezogen auf den Gesamtinhalt der Dose. Bevorzugt sind Anteile von 3 bis 20 Gew.-%.In such cases, in which there is a risk that a liquid cleaning agent flows through joints into the interior of a device housing and causes malfunctions there, it is advantageous to use the agent in the form of a foam. This foam should be so stiff and stable that it cannot penetrate into joints or cracks in the surfaces to be treated. In order to prepare a foam aerosol for this purpose, the care product according to the invention is filled into conventional aerosol cans and an aerosol propellant or an aerosol propellant mixture is pressed into these after sealing with suitable aerosol valves. Primarily pressure-liquefied propellant gases such as dichlorodifluoromethane (FKW 12) and / or dichlorotetrafluoroethane (FKW 114) or compressed propellant gases used in aerosol technology, such as carbon dioxide, can be used. The need for propellant gas to produce a stable foam when the aerosol valve is actuated (after shaking the aerosol can) is in the order of 2 to 30% by mass, based on the total content of the can. Portions of 3 to 20% by weight are preferred.

Man kann die durch Schütteln erzeugte Emulsion des erfindungsgemäßen Pflegemittels auch durch Einschlagen von Luft mittels eines Schneebesens oder anderer Schaumschlag-Geräte verschäumen. Ebenso kann man bei Zusatz eines Treibgases zum Pflegemittel (d.h. bei einer Formulierung des Mittels als Schaumaerosol) aus einer Aerosoldose mit Ventil und Schaumkopf Schaum erzeugen. Dieser Schaum wird wierderum auf ein Tuch bzw. ein Papier-Vlies aufgebracht oder auch direkt auf die zu behandelnde Fläche. Letzteres empfiehlt sich insbesondere dann, wenn das Reinigungsmittel längere Zeit auf die eventuell stark verschmutzte Fläche einwirken soll, bevor es wieder mechanisch durch Ab-und Trockenreiben entfernt wird. Das kann bei hartnäckigen Verschmutzungen mitunter sogar wiederholt erforderlich werden.The emulsion of the care product according to the invention produced by shaking can also be foamed by blowing in air using a whisk or other foam whisking device. Likewise, if a propellant gas is added to the care product (i.e. when the product is formulated as a foam aerosol), foam can be generated from an aerosol can with valve and foam head. This foam is then applied to a cloth or paper fleece or directly to the surface to be treated. The latter is particularly recommended if the cleaning agent is to act on the possibly heavily soiled surface for a long time before it is mechanically removed by rubbing it off and on again. In the case of stubborn soiling, this can sometimes be necessary repeatedly.

Die Erfindung betrifft ferner ein Pflegemittel zur Reinigung von empfindlichen Oberflächen, bestehend aus einer wäßrigen und einer nicht-wäßrigen flüssigen Phase, das dadurch gekennzeichnet ist, daß die nicht-wäßrige Phase aus FKW 113 besteht, das Mittel das Triethanolamin-Salz eines Alkylschwefelsäurehalbesters mit 10 bis 12 Kohlenstoffatomen in der Alkylgruppe enthält und frei ist von Wachs. In diesem Fall ist also die Gegenwart eines Silikonöles nicht erforderlich. Vorzugsweise ist das erfindungsgemäße Pflegemittel nach dieser Ausführungsform auch frei von sonstigen nicht flüchtigen Komponenten. Die oben gemachten Angaben betreffend Menge von Tensid und FKW 113, Mengenverhältnis wäßrige Phase/organische Phase, Art und Anteil eines Treibgases sowie Formulierung eines Aerosols gelten hier ebenfalls.The invention further relates to a care product for cleaning sensitive surfaces, consisting of an aqueous and a non-aqueous liquid phase, which is characterized in that the non-aqueous phase consists of HFC 113, the agent, the triethanolamine salt of an alkylsulfuric acid half-ester with 10 contains up to 12 carbon atoms in the alkyl group and is free of wax. In this case, the presence of a silicone oil is not necessary. According to this embodiment, the care product according to the invention is preferably also free of other non-volatile components. The information given above regarding the amount of surfactant and HFC 113, the quantitative ratio of aqueous phase / organic phase, the type and proportion of a propellant gas and the formulation of an aerosol also apply here.

Auch dieses Pflegemittel besitzt ein sehr hohes Reinigungspotential gegenüber allen Verschmutzungen. Wegen der Abwesenheit eines wasserlöslichen Silikonöles kommt es nicht zur Ausbildung des stark antistatisch wirkenden Films und auch nicht zu einem Seidenglanz. Das so modifizierte erfindungsgemäße Mittel eignet sich jedoch besonders gut zur Reinigung von Oberflächen, auf denen keine Rückstandsfilme verbleiben dürfen. Besonders gut eignet - sich dieses erfindungsgemäße Mittel zur Reinigung von Compact-Disk-Platten.This care product also has a very high cleaning potential against all soiling. Due to the absence of a water-soluble silicone oil, there is no formation of the strongly antistatic film and also no silky sheen. However, the agent according to the invention modified in this way is particularly suitable for cleaning surfaces on which no residue films may remain. This agent according to the invention is particularly suitable for cleaning compact disk disks.

Die Erfindung wird durch die folgenden Beispiele näher erläutert.The invention is illustrated by the following examples.
