Bei der Abfüllung von Lebensmitteln müssen die Gefäße mit Hilfe von speziellen Transportbändern, insbesondere Flaschentransportbändern, bewegt werden. Solche Transportbänder bestehen in der Regel aus Edelstahl, in seltenen Fällen aus Kunststoff. Um die Bewegung der Gefäße, d.h. Flaschen oder sonstige Gefäße aus Glas oder Kunststoff, zu erleichtern müssen die Bänder mit einem Gleitmittel (sog. Bandschmier- oder Kettengleitmittel) geschmiert werden.When filling food, the containers must be made using special Conveyor belts, especially bottle conveyor belts, are moved. Such conveyor belts are usually made of stainless steel, in rare cases plastic. To the Movement of the vessels, i.e. Bottles or other vessels made of glass or plastic, too The belts must be lightened with a lubricant (so-called belt lubricant or chain lubricant) be lubricated.

Mit den obenerwähnten Aktivsubstanzen, allein oder in Kombination miteinander, und gegebenenfalls mit Zusatz von Hilfsmitteln und Additiven wie z.B. Lösungsmitteln, Komplexierungsmitteln, thresholdaktiven Substanzen, Hydrotrope, Harnstoff, Biozide, speziellen organischen Säuren und anderen mehr kann man vielfältige Bandschmiermittel formulieren.With the above-mentioned active substances, alone or in combination with each other, and optionally with the addition of auxiliaries and additives such as e.g. solvents Complexing agents, threshold-active substances, hydrotropes, urea, biocides, special organic acids and other more you can use a variety of belt lubricants formulate.

Allen diesen Formulierungen ist jedoch gemeinsam, dass sie als klare, wässerige Lösungen vorliegen. Die Formulierungen sind außerdem so gestaltet, dass die Wirkstoffe auch bei hoher Verdünnung stets in Lösung bleiben, da ihre Ausfällung die Verstopfung der Spritzdüsen und die Abnahme der Wirksamkeit verursachen würde.However, all these formulations have in common that they are clear, aqueous solutions available. The formulations are also designed so that the active ingredients also high dilution always remain in solution, since their precipitation the constipation of the Spray nozzles and the decrease in effectiveness would cause.

Bei der Anwendung der bekannten Bandschmiermittel können verschiedene Probleme entstehen, welche bis heute nicht oder nur teilweise gelöst worden sind:Various problems can arise when using the known belt lubricants arise which have not been solved or only partially solved:

Es kann durch eine zu hohe Empfindlichkeit gegenüber verschiedenen Ionen im Betriebswasser wie beispielsweise Carbonat-, Hydrogencarbonat-, Sulfat oder Erdalkaliionen eine Ausfällung verursacht werden, welche zur Verstopfung der Sprühdüsen und zur Abnahme der Leistung führt. It can be caused by a too high sensitivity to different ions in the Process water such as carbonate, bicarbonate, sulfate or alkaline earth ions a precipitate is caused, which leads to clogging of the spray nozzles and Decrease in performance leads.

Durch eine ungenügende biozide Wirkung kann das Transportband von Mikroorganismen befallen werden, während eine zu starke biozide Wirkung zu Problemen in der Funktion von Kläranlagen führen kann.Due to an insufficient biocidal effect, the conveyor belt of microorganisms be attacked while having too strong a biocidal effect causing problems in the function of Sewage treatment plants.

Bei einer zu starken Schaumentwicklung wird die Flaschenkontrolle an den Lichtschranken gestört.If the foam development is too strong, the bottle control is switched on at the light barriers disturbed.

Eine starke Empfindlichkeit gegenüber Resten von der abzufüllenden Flüssigkeit wie z.B. Bier, Milch, Fruchtsäfte, Mineralwasser auf dem Transportband bewirkt eine rasche Abnahme der Schmierwirkung der obengenannten Bandschmiermittel.A strong sensitivity to residues from the liquid to be filled, e.g. Beer, milk, fruit juices, mineral water on the conveyor belt causes a quick Decrease in the lubricating effect of the above-mentioned belt lubricants.

Zudem tritt die der Schmierwirkung am Anfang der Produktion häufig verzögert ein.In addition, the lubricating effect is often delayed at the start of production.

Daher ist es die Aufgabe der vorliegenden Erfindung, ein Bandschmier- oder Kettengleitmittel bereitzustellen, das die oben gezeigten Nachteile des Standes der Technik nicht aufweist, und zudem leicht und preiswert herzustellen ist.It is therefore the object of the present invention to provide a belt lubricant or chain lubricant To provide that does not have the disadvantages of the prior art shown above has, and is also easy and inexpensive to manufacture.

Diese Aufgabe wird durch das erfindungsgemäße Bandschmier- oder Kettengleitmittel gemäß Anspruch 1, daß mindestens einen oder mehrere Ester der Formeln I, II, III, oder IV enthält, gelöst.This object is achieved by the belt lubricant or chain lubricant according to the invention according to claim 1, that at least one or more esters of the formulas I, II, III, or IV contains, solved.

Die erfindungsgemäßen Bandschmier- oder Kettengleitmittel werden entweder als konzentrierte Emulsionen, insbesondere als wässerige Emulsionen mit 1-25 Gew.-% Wirkstoff, ganz besonders bevorzugt 5-10 Gew.-% Wirkstoff, oder auch als wasserfreie Konzentrate hergestellt und in den Handel gebracht (vergleiche Patentanspruch 10).The belt lubricants or chain lubricants according to the invention are either concentrated Emulsions, especially as aqueous emulsions with 1-25% by weight of active ingredient, very particularly preferably 5-10% by weight of active ingredient, or also as anhydrous concentrates manufactured and put on the market (see claim 10).

Die erfindungsgemäßen Bandschmiermittel werden daher nie konzentriert angewendet. In der Regel werden sie als relativ konzentrierte Emulsionen an die Endverbraucher geliefert, z.B. 0,5-25 % an Fettsäureester, Emulgator(en) und weiteren Komponenten zusammen. Diese konzentrierten Emulsionen werden dann bei deren Anwendung stark verdünnt (auf 5 bis 350 mg/kg Gehalt an Wirkstoffen). Bevorzugt ist es aber auch, dass die erfindungsgemäßen Bandschmiermittel als weit höher konzentrierte Emulsionen oder als wasserfreie Mischungen der einzelnen Komponenten (Konzentrate) hergestellt und geliefert werden. Diese werden dann ebenfalls von den Endverbrauchern auf die Anwendungskonzentration (5-350 mg/kg Wirkstoffe total) verdünnt. The belt lubricants according to the invention are therefore never used in a concentrated manner. In usually they are delivered to end users as relatively concentrated emulsions, e.g. 0.5-25% of fatty acid ester, emulsifier (s) and other components together. These concentrated emulsions are then greatly diluted when used (to 5 up to 350 mg / kg active ingredient content). However, it is also preferred that the inventive Belt lubricants as much higher concentrated emulsions or as anhydrous ones Mixtures of the individual components (concentrates) are produced and delivered. These are then also determined by the end users on the application concentration (5-350 mg / kg active ingredients total) diluted.

In einer alternativen Ausführungsform können aber auch die Bandschmier- oder Kettengleitmittel, enthaltend einen oder mehreren Ester der Formeln I, II, III, IV als Additiv zu handelsüblichen Bandschmiermitteln auf Basis von kationischen, anionischen oder nicht ionischen Tensiden, die als wässerige Lösung vorliegen, zugegeben werden (Patentanspruch 15).In an alternative embodiment, however, the belt lubrication or Chain lubricant containing one or more esters of the formulas I, II, III, IV as an additive to commercially available belt lubricants based on cationic, anionic or not ionic surfactants, which are present as an aqueous solution, are added (claim 15).

In den Unteransprüchen sind vorteilhafte Ausführungsformen der Erfindung enthalten.Advantageous embodiments of the invention are contained in the subclaims.

Die Erfinder haben nun überraschenderweise festgestellt, daß man wasserunlösliche Wirkstoffe, d.h. die oben beschriebenen Ester der Formeln I, II, III, IV, d.h. wasserunlösliche Wirkstoffe als milchige Emulsionen oder Mikroemulsionen, welcher opaleszent oder klar sein können als Bandschmiermittel verwendet. Bisher wurden im Stand der Technik nämlich nur stets klare, wässerige Lösungen verwendet bei denen immer die Gefahr besteht, daß die Wirkstoffe ausfallen und Dispersionen gebildet werden, welche die Spritzdüsen verstopfen. Erfindungsgemäß werden aber solche Emulsionen nunmehr bereit gestellt, die gerade diese Probleme nicht aufweisen bzw. die Düsen nicht verstopfen, selbst dann nicht, wenn sie in den Leitungen brechen sollten. Als erfindungsgemäße Wirkstoffe dienen wasserunlösliche bzw. sehr schwach lösliche Ester, d.h. Einfach- oder Mehrfachester, hauptsächlich sogenannte Fettsäureester, wie sie in den folgenden Formeln I-IV:

Figure 00040001
beschrieben sind, wobei R, R', R", jeweils unabhängig voneinander, Alkylreste mit 1 bis 22 Kohlenstoffatomen, gesättigt oder einfach oder mehrfach ungesättigt, linear oder verzweigt, substituiert oder unsubstituiert sind, und die Summe der Kohlenstoffatome der drei Reste R, R' und R" größer oder gleich acht ist.The inventors have now surprisingly found that water-insoluble active substances, ie the esters of the formulas I, II, III, IV described above, ie water-insoluble active substances, are used as milky emulsions or microemulsions, which can be opalescent or clear as belt lubricants. So far, only clear, aqueous solutions have always been used in the prior art in which there is always the risk that the active ingredients will precipitate out and form dispersions which clog the spray nozzles. According to the invention, however, emulsions are now provided which do not have these problems or which do not clog the nozzles, even if they should break in the lines. Water-insoluble or very poorly soluble esters, ie single or multiple esters, mainly so-called fatty acid esters, as used in the following formulas I-IV, serve as active substances according to the invention:
Figure 00040001
are described, wherein R, R ', R ", each independently of one another, alkyl radicals having 1 to 22 carbon atoms, saturated or mono- or polyunsaturated, linear or branched, substituted or unsubstituted, and the sum of the carbon atoms of the three radicals R, R 'and R "is greater than or equal to eight.

Die Technik zur Herstellung solcher stabilen Emulsionen mit Hilfe von geeigneten bekannten Emulgatoren bzw. deren Konservierung mit Bioziden ist allgemein bekannt.The technique for producing such stable emulsions using suitable known ones Emulsifiers and their preservation with biocides are generally known.

Die erfindungsgemäßen Formulierungen bieten gegenüber konventionellen Bandschmiermitteln enorme Kostenvorteile, da die Fettsäureester der Formeln I, III, IV bereits in extrem tiefen Konzentrationen, d.h. bei 10 ppm sehr wirksam sind. Außerdem sind die erfindungsgemäßen Formulierungen sehr betriebssicher und zeigen nicht die bekannten Nachteile wie Wasserhärteempfindlichkeit, überhöhte Schaumbildung, verzögerte Eintretung der Schmierwirkung, Empfindlichkeit gegenüber pH-Schwankungen, Nachlassen der Wirkung im Kontakt mit abzufüllenden Flüssigkeiten. Sie sind außerdem ökologisch sehr vorteilhaft.The formulations according to the invention offer compared to conventional belt lubricants enormous cost advantages, since the fatty acid esters of formulas I, III, IV are already in extreme low concentrations, i.e. are very effective at 10 ppm. Besides, they are Formulations according to the invention are very reliable and do not show the known Disadvantages such as sensitivity to water hardness, excessive foaming, delayed entry the lubricating effect, sensitivity to pH fluctuations, weakening of the effect in contact with liquids to be filled. They are also very ecological advantageous.

Erfindungsgemäß geeignet sind alle wasserunlöslichen oder schwach wasserlöslichen Ester, welche sich aufbauen aus der einfachen oder mehrfachen Veresterung zwischen Carbonsäuren (mit einer oder mehreren -COOH-Gruppen) und Alkoholen (mit einer oder mehreren OH-Gruppen) bzw. mit Verbindungen, welche sowohl die -COOH als auch die -OH-Funktion besitzen (Hydroxycarbonsäuren). Die erfindungsgemäßen Ester können insbesondere noch freie -COOH oder -OH Gruppen enthalten und werden durch die folgenden allgemeinen Formeln dargestellt:

Figure 00050001
Suitable according to the invention are all water-insoluble or slightly water-soluble esters which are built up from the single or multiple esterification between carboxylic acids (with one or more -COOH groups) and alcohols (with one or more OH groups) or with compounds which both -COOH and the -OH function (hydroxycarboxylic acids). The esters according to the invention can in particular still contain free -COOH or -OH groups and are represented by the following general formulas:

Sie können auch Mehrfachester mit mehreren

sein,
wobei R, R' und R" Alkylreste mit 1 bis 22 Kohlenstoffatomen, gesättigt oder einfach oder mehrfach ungesättigt, linear oder verzweigt, substituiert oder unsubstituiert, sind, und wobei die Summe der Kohlenstoffatome der Reste R, R', R" größer oder gleich 8 ist.You can also have multiple testers with multiple

wherein R, R 'and R "are alkyl radicals having 1 to 22 carbon atoms, saturated or mono- or polyunsaturated, linear or branched, substituted or unsubstituted, and wherein the sum of the carbon atoms of the radicals R, R', R" is greater than or equal to 8 is.

Diese Ester wirken in wässeriger Emulsion, bereits in extrem tiefen Konzentrationen von 10 ppm, sehr stark schmierend. Die erfindungsgemäßen Emulsionen neigen nicht zur Verstopfung der Spritzdüsen. Die Schmierwirkung ist weitgehend vom pH, Wasserbeschaffenheit (Elektrolytgehalt, Wasserhärte usw.) unabhängig.These esters work in aqueous emulsion, even in extremely low concentrations of 10 ppm, very lubricating. The emulsions according to the invention do not tend to Blockage of the spray nozzles. The lubricating effect is largely dependent on pH, water quality (Electrolyte content, water hardness, etc.) independently.

Eventuelle Verschmutzung der Transportbänder durch die abzufüllenden Flüssigkeiten wie Bier, Milch, Mineralwasser, Fruchtsäfte verursachen kaum eine Abnahme der Schmierwirkung.Possible contamination of the conveyor belts by the liquids to be filled such as Beer, milk, mineral water, fruit juices hardly cause a decrease in the lubricating effect.

Die Schmierwirkung tritt augenblicklich ein. Die Transportbänder werden sofort optimal benetzt. Die Schaumbildung ist optimal, es entstehen keine Probleme an den Lichtschranken. The lubricating effect occurs immediately. The conveyor belts are optimal immediately wetted. The foam formation is optimal, there are no problems with the light barriers.

Sofern eine biozide Wirkung des Bandschmiermittels gewünscht wird, kann man handelsübliche Biozide zusetzen. Hierbei besteht die Möglichkeit, die Biozide nach den besonderen Kundenanforderungen zu wählen wie z.B. formaldehydfreie Biozide, Abwesenheit von Halogenen usw..If a belt lubricant is desired to have a biocidal effect, one can Add commercially available biocides. There is the possibility of the biocides according to the special customer requirements such as formaldehyde-free biocides, Absence of halogens etc.

Als Emulgatoren eignen sich alle handelsübliche Emulgatoren, unabhängig von ihrem ionischen Charakter (anionische, nichtionogene, amphotere oder kationische Emulgatoren, allein oder in Kombination miteinander). Bevorzugt sind nichtionogene Emulgatoren wie z.B. Fettalkohol- oder Fettsäureethoxylate bzw. die analogen Ethoxo-Propoxilate (sog. "EO-PO-Tenside"). Diese Emulgatoren sind in der Regel weitgehend unempfindlich in Bezug auf die Wasserhärte und pH-Wert. Bei geeigneter Auswahl sind sie gut biologisch abbaubar und enthalten weder Stickstoff noch Phosphor.All commercially available emulsifiers are suitable as emulsifiers, regardless of their ionic character (anionic, non-ionic, amphoteric or cationic emulsifiers, alone or in combination). Nonionic emulsifiers such as e.g. Fatty alcohol or fatty acid ethoxylates or the analog ethoxo-propoxylates (so-called "EO-PO surfactants"). These emulsifiers are usually largely insensitive to the water hardness and pH. With a suitable selection, they are readily biodegradable and contain neither nitrogen nor phosphorus.

Deren Konzentration in der Formulierung richtet sich nach der Stabilität der konzentrierten Ester-Emulsion, welche den industriellen Anforderungen genügen muss (unter Umständen mehrere Monate). Die Konzentration der Emulgatoren liegt zwischen 0,5-50 Gew.-%, bezogen auf den oder die zu emulgierenden Ester.Their concentration in the formulation depends on the stability of the concentrated Ester emulsion, which must meet industrial requirements (under certain circumstances several months). The concentration of the emulsifiers is between 0.5-50% by weight, based on the ester or esters to be emulsified.

In einer alternativen Ausführungsform der Erfindung können die erfindungsgemäßen Bandschmier- oder Kettengleitmittel enthaltend einen oder mehreren Ester der Formeln I, II, III oder IV zu konventionellen d.h. handelsüblichen Bandschmiermitteln auf Basis von kationischen, anionischen oder nicht ionischen Tensiden hinzugefügt werden. Die konventionellen Bandschmiermittel sind im wesentlichen wässerige Lösungen. Ein handelsübliches Bandschmiermittel wird z.B. in der DE-A-4244536 beschrieben. Die Schmiermittel werden auf wässerige Basis hergestellt, d.h. die Schmiermittel enthalten etwa 60-90 Gew.% Wasser. Ein bevorzugtes Schmiermittel gemäß der DE-A-4244536 weist folgende Zusammensetzung auf: Gew.-% Milchsäure (80%ig) 2-10 N-Oleyl-1,3-diaminopropan 3-15 N-Lauryl-1,3-diaminopropan 0,5-4,5 Alkyl (C16-C18) polyethylenglykolether (9EO)-essigsäure 0,5-4,5 Alkyl (C13) polyethylenglykolether (6 Mol EO) 0,5-3,0 Alkyl (C13) polyethylenglykolether (12 Mol EO) 0,5-3,0 Rest Wasser (destilliert, enthärtet) In an alternative embodiment of the invention, the belt lubricants or chain lubricants according to the invention containing one or more esters of the formulas I, II, III or IV can be added to conventional, ie commercially available belt lubricants based on cationic, anionic or nonionic surfactants. The conventional belt lubricants are essentially aqueous solutions. A commercially available belt lubricant is described, for example, in DE-A-4244536. The lubricants are produced on an aqueous basis, ie the lubricants contain about 60-90% by weight of water. A preferred lubricant according to DE-A-4244536 has the following composition: Wt .-% Lactic acid (80%) 2-10 N-oleyl-1,3-diaminopropane 3-15 N-lauryl-1,3-diaminopropane 0.5-4.5 Alkyl (C 16 -C 18 ) polyethylene glycol ether (9EO) acetic acid 0.5-4.5 Alkyl (C 13 ) polyethylene glycol ether (6 mol EO) 0.5-3.0 Alkyl (C 13 ) polyethylene glycol ether (12 mol EO) 0.5-3.0 Rest of water (distilled, softened)

Die Schmiermittelzusammensetzung kann noch Hilfs- und/oder Zusatzstoffe enthalten. In Betracht kommen hierbei insbesondere Lösungsvermittler wie Alkohole, Polyalkohole, Ether oder Polyether, insbesondere Isopropanolbutylalkohol, Butyldiglykol oder Ethylenglykolether.

    ERLÄUTERUNG DER RESULTATEEXPLANATION OF RESULTS

    Die erzielten Reibungskoeffiziente beweisen, dass die erfindungsgemäßen Formulierungen der Beispiele 1A-9A bzw. 1B-9B wesentlich leistungsfähigere Schmiermittel sind als die verglichenen konventionellen Formulierungen basierend auf wasserlöslichen Tensiden. Die notwendige Schmierwirkung (Reibungskoeffizienten ≤ 0,12 werden als sehr gut betrachtet) wird bei den erfindungsgemäßen Formulierungen schon bei extrem tiefen Konzentrationen von 25 ppm Wirkstoff erreicht. Diese Konzentration liegt um ein Vielfaches niedriger als die übliche Anwendungskonzentration von konventionellen Bandschmiermitteln basierend auf wasserlöslichen Tensiden (diese liegt bei den meisten handelsüblichen Bandschmiermitteln bei ca. 150-350 ppm).The coefficients of friction achieved prove that the formulations according to the invention Examples 1A-9A and 1B-9B are much more powerful lubricants than that compared conventional formulations based on water-soluble surfactants. The necessary lubrication effect (friction coefficients ≤ 0.12 are considered very good) is in the formulations according to the invention even at extremely low concentrations reached by 25 ppm of active ingredient. This concentration is many times lower than that Usual concentration of conventional belt lubricants based on water-soluble surfactants (this is the case with most commercially available belt lubricants at approx. 150-350 ppm).

    In keinem Fall haben die erfindungsgemäßen Formulierungen eine störende Schaumentwicklung entfaltet.In no case do the formulations according to the invention interfere with the development of foam unfolded.
