The present invention relates to a lubricant concentrate, of which the diluted use solution is suitable for lubricating and cleaning of conveyor belt installations in the food industry, particularly by means of immersion or automatic belt lubricating systems. The invention further relates to a process for the production of the lubricant concentrate or the aqueous use solution of the lubricant concentrate as well as the use of the lubricant concentrate and the aqueous use solution for lubricating and cleaning of conveyor belt installations, in particular by means of immersion lubricating or automatic belt lubricating installations, particularly in the food industry. The use thereby particularly relates to filling foods, especially with beverages, of glass and plastic bottles, particularly in this case polyethylene terephthalate (PET), polyethylene naphthalate (PEN) or polycarbonate (PC), boxes, metal cans, glasses, vessels, refillable cans, barrels or vessels, such as KEGs, beverage containers, paper and cardboard holders and the like. In food industry the conveyance of beverage packings made of metal, glass, paper, cardboard and/or plastic using a lubricant concentrate, respectively its aqueous use solution, is commonly applied. Presently beverages are being sold in several different containers. Thus, beverages are offered in glass bottles, plastic bottles, plastic containers, metal cans, boxes, wax cartons, etc. In the filling plants these containers have to be transported during filling to several stations. Generally this occurs by means of feed or conveyance belt installations (having chains or tracks), which usually consist of stainless steel or plastic, insofar as these containers concern glass containers, or the conveyance belt installations consist of plastic materials like polypropylene or certain polyacetates, insofar as these containers concern other than glass bottles or glass containers. Following hereafter, such installations are referred to as feed and conveyance installations or as conveyor belt installations. During filling and transport of the mentioned containers sometimes a turning over or a blocking of the containers may occur, while the conveyor belts are running further without hindrance. Especially in this case a sufficient lubrication of the conveyor belts is required in order that the belt can move forward without hindrance even when the containers on the belt cannot move forward during some time. 2 For this purpose it is required, as already mentioned before, to lubricate and to clean the parts of the feed and conveyance installations, which come into contact with the beverage containers, sufficiently. If the conveyance installations are not lubricated sufficiently this can, on the one hand, lead to the falling down of the containers, or on the other hand, have the result that they do not stop, although the respective filing up, cleaning or labelling station has already been reached. Both kind of malfunctions can lead to longer down time of the conveyance installations and to considerable loss of capacity. Presently, there are several different types of lubricant concentrates known, which can in principal be divided into 4 main groups: i) lubricants on the basis of soap, ii) lubricants on the basis of polysiloxanes (such as those described in WO 01/18160), iii) lubricants on the basis of fatty amines (such as those described in WO 98/16603) and iv) lubricants on the basis of phosphate esters. Additionally, the pH-value of the lubricant compositions (both the concentrate and the diluted aqueous use solution) may differ, since many of the known compositions have a pH-value in the range between 5 and 8, but there are also lubricant compositions known having a pH-value between 7 and 11. Lubricant compositions having a pH-value within the acid up to the neutral range have the advantage that there is less stress cracking observed when employing plastic material, such as polyethylene terephthalate (PET) bottles. For each lubricants concentrate the individual components have to be harmonized to provide stable compositions for the pH-range intented to be applied. Some of the lubricants based on phosphate esters also include an amine compound. US 6,756,347 Bl discloses lubricant compositions comprising at least one alkyl alkoxylated phosphate ester, one aryl alkoxylated phosphate ester, one aromatic or linear quaternary ammonium antimicrobial agent and a liquid carrier, such as water. The phosphate components are in both cases (alkyl alkoxylated or aryl alkoxylated) either a phosphate monoester or a phosphate diester. The pH-value of said compositions is in the range between 6 and 8,5. Another lubricant on the basis of phosphate esters is disclosed in WO 00/22073. That lubricant comprises a phosphate monoester with the ester component on the basis of polyethylene oxide, which is additionally substituted with an amide. A disadvantage of said lubricant composition is that the synthesis of the phosphate ester component is rather complex including educts such as phosphorous pentoxide, therefore, the production of the lubricant concentrate is rather cost-intensive. 3 Another lubricant composition based on phosphate esters is disclosed in JP-B 6330079 comprising an alkyl amine and an alkyl (poly)alkoxylated phosphate monoester or a mixture of the phosphate monoester and the respective phosphate diester. Said compositions are employed at a pH-value between 5 and 8. The object of the present invention is the provision of a new and stable lubricant concentrate on basis of phosphate esters, which can be easily produced at low costs. Furthermore, the new lubricant concentrate should have at least a comparable or, in preferred embodiments, an enhanced lubricity causing reduced friction compared to the known lubricants based on phosphate esters. It is also an object of the invention to provide a lubricant concentrate causing fast formation of the lubricant film on the conveyor belt installations (tracks or chains). Furthermore, it is also an object of the present invention that the lubricant film can be very uniformly applied to the conveyor belt installations. The object is achieved by a lubricant concentrate containing the following components (i) at least one amine; (ii) at least one phosphate according to the general formula (I), wherein R1A, R1b and R1c independently from each other are the same or different and indicate C1-C3o-alkyl or -([CH2]m-O)n-R1d, where m is 2 or 3, n is 1 to 10 and R1d is C1-C30-alkyl, phenyl or phenyl-(C1-C10-alkyl)-; (iii) at least one acid (iv) optionally at least one ether carboxylic acid compound with the general formula (II) R20-(O(CH2)m)nOCH2COO-M+ (II) wherein R20 is a saturated, linear or branched alkyl rest with 1 to 22 carbon atoms or a mono or polyunsaturated linear or branched alkenyl or alkynyl rest with 2 to 22 carbon atoms or 4 an aryl rest optionally substituted with at least one C1-C22 alkyl, C2-C22 alkenyl or C2- C22-alkynyl, n is a positive number between 0 and 30, and m is 2 or 3, M is hydrogen or an alkali metal; (v) optionally at least one further aid or additive; whereby the portion of the components (i) + (ii) + (iii) with respect to the concentrate is 1 to 100 wt. %, and said optional components (iv) and (v) may be present in portions up to 99 wt. %, whereby the portions (i) - (v) are chosen such that the total results in 100 wt. %. The advantage of the lubricant concentrate of the present invention is that it can be easily produced at low cost and enhanced lubricity is provided compared to those lubricant compositions based on phosphate esters known from the state of the art. Enhanced lubricity causes reduced friction on the conveyor belt installations (being determined by the friction coefficient ) and therefore improved conveyance of the employed beverage packings regardless of their material of the packings or the conveyor's chains. A further advantage is that the lubricating film is formed faster on the conveyor belt installations (tracks or chains). This implies that an improved number of beverage packings (improved capacity) can be handled on the conveyor belt installations, since these systems can only be operated having a sufficient amount of lubricant on the tracks or chains forming a preferably uniform lubricating film. In case there is no sufficient and/or uniform lubrication provided on the tracks or chains of the lubricant belt installations, beverage packings such as bottles cause either a blocking of the whole system or they may even be destoyed by falling from the tracks or chains. A further advantage of the lubricant concentrate of the present invention is that the lubricating film is formed more uniformly and for a longer period of time on the conveyer belt installations. Due to the more uniformly formation of the lubricating film on the tracks or chains the beverage packings can be transported more smoothly. This also implies that a fewer amount of lubricant concentrate is required to provide a uniform lubricating film, which is attained for a longer period of time. As a further consequence, less solvent, which is used for diluting the lubricant concentrate, in particular water, is consumed causing additional cost reduction. 5 The lubricant concentrate of the present invention can be employed for all types of conveyor belt systems (such as plastic chains or stainless steel chains) and all types of beverage packing materials (such as glass or plastic containers). In contrast to many of the known lubricant concentrates, the lubricant concentrate of the present invention has a significant stability at a pH-range between 3 and 9, since it can be stored as a single phase system (in form of a clear solution) over several weeks. Preferred lubricant compositions, containing as a further (optional) component at least one ether carboxylic acid according to the below indicated general formula II, have the advantage that besides a further improvement in terms of lubricity also improved water compatibility can be observed in comparison to those lubricant concentrates of the present invention without these optional component. Lubricant concentrates additionally containing an ether carboxylic acid are good sulphate controllers having an excellent hard water tolerance.

It has to be indicated that due to the presence of further components containing cations, for example protons, such as the acids of component (iii), the employed amines may be partially or completely transferred into the corresponding salts during the preparation and/or storage of the lubricant concentrate. This is particularly relevant if the lubricant concentrate contains a solvent, such as water, or in the corresponding aqueous use solution of the lubricant concentrate.

For example, the compounds mentioned in the table can be obtained under the trade name AKYPO from the company CHEM-Y as special surfactant. The component (v): The component (v) is optional and therefore only possibly contained in the lubricant concentrate according to the invention. As component (v), the lubricant concentrate according to the present invention may contain one or more of the following compounds also assigned as aid or additive, which can be independently selected from each other.

Besides water and/or PEG's also the following aids and/or additives qualify as component (v): solution intermediates, for example alcohols, polyalcohols, ether or polyether, especially isopropanol, butylglycol, butyldiglycol or ethyleneglycolether; Examples of components which qualify as solution intermediates can be found in the below table. 19 The amount of the solution intermediates to be used should be determined according to the individual amine to used, the professional will calculate the required solution intermediate in the individual case by means of trial and error. In general additions of solution intermediates in the range of 5 to 20 wt %, calculated on basis of the total composition, will be sufficient. Optionally, two or more of the solution intermediates may be employed as a mixture. Further, as aid and / or additives according to the present invention particularly non-ionic and / or amphoteric surfactants merit consideration, for example fatty alcohols and alkoxylated fatty alcohols. These surfactants can improve the moistening of the chain and conveyor belts insofar as this is required in an individual case. In general surfactant additions in the range of 1 to 5 wt. %, calculated on basis of the total composition are sufficient for this purpose. Also, polyalkylene glycols which are not included in the above indicated polyethylene glycols can be employed. Additionally, one or more phosphate mono- or diesters as those indicated in US 6,756347 Bl, WO 98/16603 or JP-B 6330079 also qualify as component (v). Further additives include anti foaming agents, foam regulators, foam stabilizers, moistening agents, coupling agents, chelation agents or chelate formers or solubility improvers, biocides, like e.g. bactericides, corrosion inhibitors, pH-buffers, as well as combinations of representatives of the previously mentioned classes of substances. 20 Unless stated otherwise, each of the alkyl (or alkylene), alkenyl (or alkenylene) or alkkynyl (or alkynylene) residues or fragments defined in formulas (I) to (XX), such as R1 to R21 , R1a to R1d or A1 to A12 may independently be linear or branched, acyclic or cyclic. This also applies when they are part of other groups, for example in alkoxy groups (C1- C10-alkyl-O-), alkoxycarbonyl groups or amino groups, or when they are substituted. Examples for alkyl groups are: methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl. This comprises both the n-isomers of these residues and isopropyl, isobutyl, isopentyl, sec-butyl, tert-butyl, neopentyl, 3,3-dimethylbutyl etc.. Furthermore, unless stated otherwise, the term alkyl here also includes - besides the unsubstituted alkyl residues - optinally substituted alkyl residues which are substituted by one or more, for example one, two, three or four, identical or different residues, for example aryl, heteroaryl C1-C10-alkoxy, -CF3, -OH, -NH2 or halogen. The substituents may be present in any desired position of the alkyl group. The term alkyl here also expressly includes cycloalkyl residues and cycloalkyl-alkyl-residues (alkyl substituted by cycloalkyl), where cycloalkyl contains at least three carbon atoms. Examples for such cycloalkyl residues are cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl and cyclooctyl. All cycloalkyl groups may be unsubstituted or optionally substituted by one or more further residues, as exemplified above in the case of the alkyl groups. The same applies to the respective alkylene or cycloalkylene fragments. Examples for alkenyl and alkynyl groups are the vinyl residue, the 1-propenyl residue, the 2-propenyl residue (allyl residue), the 2-butenyl residue, the 2-methyl-2-propenyl residue, the 3-methyl-2-butenyl residue, the ethynyl residue, the 2-propynyl residue (propargyl residue), the 2-butynyl residue or the 3-butynyl residue. Unless indicated otherwise the term alkenyl also includes cycloalkenyl residues and cycloalkenyl-alkyl-residues (alkyl substituted by cycloalkenyl) containing at least three carbon atoms. The same applies to the respective cycloalkynyl groups. Examples for cycloalkenyl residues are cyclopentenyl, cyclohexenyl, cycloheptenyl and cyclooctenyl. The same applies to the respective alkenylene, cycloalkenylene, alkynylene or cycloalkynylene fragments. Unless indicated otherwise, the terms alkenyl, alkynyl, etc. also include polyunsaturated residues such as alk-dienyl, alk-trienyl, alk-diynyl, etc. According to the present invention, aryl is a residue derived from mono-, bicyclic or polycyclic aromatics having between 6 and 30, preferably 6 or 10, carbon atoms, where the cycle does not contain any heteroatoms. In case it is not a monocycle, the term aryl includes for its second cycle also its saturated form (perhydro form) or its partially 21 unsaturated form (for example in the dihydro form or the tetrahydro form) in case the respective forms are known and stable. The term aryl as used herein comprises therefore, for example, bicyclic residues in which both cycles are aromatic as well as bicyclic residues in which only one cycle is aromatic. Such examples for heteroaryl are: phenyl, naphthyl, indanyl, 1,2-dihydronaphthenyl, 1,4-dihydronaphthenyl, indenyl or 1,2,3,4- tetrahydronaphthyl. Preferably, aryl is phenyl. Furthermore, if residues or fragments defined in formulas (I) to (XX), such as R1 to R21 , R1a to R1d or A1 to A12 comprise an aryl (or arylene) fragment, in particular phenyl, said aryl fragment may be unsubstituted or optionally substituted by one or more identical or different residues such as halogen C1-C10-alkyl, C1-C10-alkoxy, -OH, -NH2 and -CF3. Arylalkyl (such as aryl-(C1-C10-alkyl)-, in particular phenyl-(C1-C10-alkyl)-) means an alkyl residue (such as C1-C10-alkyl), which in turn is substituted by an aryl residue. It has to be emphasized that the below indicated proportions of the individual components (i) to (iii) or (i) to (v), respectively, concerning the lubricant concentrate or the corresponding diluted (for example aqueous) use solutions, refer to the proportions of the respective components before the preparation of said concentrate or use solution, i.e. it is referred to the individual components as starting material (educts) before mixing them with each other. Due to the preparation of the lubricant concentrate (mixing of the individual components) it may happen that two or more of its components form partially or completely, for example, adducts such as salts. This may also depend on the presence of further components such as solvents, for example water. Such adducts of lubricant concentrates or diluted use solutions are also covered by scope of the present invention.

Amounts of 0.5 to 20 wt. % are preferred, 0.5 to 10 wt. % is more preferred, particularly preferred are values of 1 to 3.5 wt. %. If present, the optional component (iv) is contained in the lubricant concentrate according to the invention generally in an amount of 0.1 to 50 wt. %. A value of 0.5 to 20 wt. % is preferred; 0.5 to 10 wt. % is more preferred; it has been shown that a value of 2 to 6 wt. % of phosphate triester in the lubricant concentrate according to the invention is especially preferred.

In other preferred implementations the concentrate additionally contains - besides components (i) to (iii) with same portions - 0.5 to 10 wt. % (iv) and component (v) is 70 to 98 wt. % instead, whereby all weight percentages are chosen such that a 100 % (wt / wt) concentrate will be obtained. In a particularly efficient version the concentrate according to the invention shows the following contents: (i) 2 to 6 wt.%, (ii) 2 to 6 wt. %, (iii) 1 to 3.5 wt.%, 23 (iv)2 to 6 wt. % and (v) 80 to 93 wt. %, whereby the amounts (i) - (v) are chosen such that the total results in 100 wt.%. The lubricant concentrate is preferably indjusted to a pH-value between 3 and 9, more preferred to a pH-value between 4 and 8.

Furthermore, the invention relates to a process for the preparation of the lubricant according to the invention. This is produced by mixing of the components (i), (ii) and (iii), possibly with addition of the components (iv) and (v). Water is preferred as component (v) thereby. Therefore, a further subject of the invention is a process for the preparation of a lubricant concentrate by means of mixing of the components (i) to (iii) and possibly addition of further components (iv) and/or (v). Moreover, the invention relates to a lubricant solution for lubricating and cleaning of feed and conveyance installations in the food industry. The lubricant solution (which can be assigned as diluted use solution) is obtained by mixing a lubricant concentrate (containing components (i) to (iii) and optionally (iv) or (v) as indicated above) with a solvent. Thereby, the lubricant solution is characterized by a content of the following components in combinations: a) a lubricant solution concentrate containing: 25 (i) at least one amine; (ii) at least one phosphate according to the general formula I, wherein R1a, R1b and R1c independently from each other are the same or different and indicate C1-C30-alkyl or -([CH2]m-O)n-R1d, where m is 2 or 3, n is 1 to 10 and R1d is C1-C30-alkyl, phenyl or phenyl-(C1-C10-alkyl)-; (iii) at least one acid; (iv) optionally at least one ether carboxylic acid compound with the general formula II R20-(O(CH2)m)nOCH2COO-M+ (II) wherein R20 is a saturated, linear or branched alkyl rest with 1 to 22 carbon atoms or a mono or polyunsaturated linear or branched alkenyl or alkynyl rest with 2 to 22 carbon atoms or an aryl rest optionally substituted with at least one C1-C22 alkyl, C2-C22 alkenyl or C2- C22-alkynyl, n is a positive number between 0 and 30, and m is 2 or 3, M is hydrogen or an alkali metal; (v) optionally at least one further aid or additive; whereby the portion of the components (i) + (ii) + (iii) with respect to the concentrate is 1 to 100 wt. %, and said optional components (iv) and (v) may be present in portions up to 99 wt. % (wt / wt), whereby the portions (i) - (v) are chosen such that the total results in 100 wt. %, and b) at least one solvent selected from water, polyethylene glycol, alcohol, ether and polyether; whereby component a) is diluted with component b) by a dilution factor of 2 to 10,000. 26 According to the invention this lubricant solution (diluted use solution) can be obtained from the lubricant concentrate (component a)) according to the invention by means of dilution with a solvent (component b)) and a dilution factor of 2 to 10,000, preferably 100 to 2,000, more preferably with a factor 200 to 1,000; measured in volume % (vol.%).

More preferably, component b) is water, optionally in combination with at least one further solvent of component b). It has to be indicated that it is possible to employ a lubricant concentrate, which does not contain any water, but one or more other components listed under component (v) instead, and said concentrate is diluted with water to obtain an aqueous use solution. The present invention further relates to the use of lubricant concentrates according to the art described before as chain lubricant in the food industry, particularly for the lubricating and cleaning of feed and conveyance installation in the food industry, particularly automatic chain and belt lubrication installations. The present invention particularly relates to the use of the lubricant concentrates described before in the form of a 0.01 to 50 wt. %. Additionally, the present invention relates to use of phosphate triesters according to general formula (I) for lubricating and/or cleaning of feed and conveyance installations in the food industry. Preferably, the phosphate triester is contained in a lubricant concentrate, more preferably in a lubricant solution, most preferably in an aqueous use solution. This means that the present invention relates to the use of lubricant concentrates, preferably lubricant solutions, more preferably the aqueous use solution described before as a chain gliding and lubricating means suitable for lubricating and cleaning of feed and conveyance installations, in particular by means of immersion and/or automatic belt lubricating installations, in the food industry. The products according to the invention do not cause stress crack corrosion, in contrast to standard soap products, when applied with plastic objects, and therefore can be applied in particular without problems for PET or PC-objects. Accordingly, the lubricant solutions according to the invention can find use as chain lubricant for the feed or conveyance of objects or bottles made of glass, glass covered with a plastic layer, plastics, in particular polyethyleneterephthalate (PET), polycarbonate (PC) or polyvinylchloride, tin plate 27 or aluminium, respectively varnished or plastic-layered containers made of these metals. The use thereby particularly relates to the filling up with foods, especially with beverages, of glass and plastic bottles, particularly in this case polyethylene terephthalate (PET), polyethylene naphthalate (PEN) or polycarbonate (PC), boxes, metal cans, glasses, vessels, refillable cans, barrels or vessels, such as KEGs, beverage containers, paper and cardboard holders and the like. Therefore, the invention also relates to a process for the conveyance of beverage packings made of metal, glass, paper, cardboard and/or plastic, whereby a beverage conveyance device is contacted with a lubricating and cleaning amount of an aqueous use solution, as is defined herein. The products according to the invention show, compared to known lubricants, a considerably better tolerance to water chemistry in an aqueous medium as well as considerably better gliding properties. Therewith, the desired technical properties of the lubricant concentrate, respectively the aqueous lubricant solution, can be adjusted purposefully by the choice of the triester and/or the amine, respectively the anion of the amine. The following examples and comparative examples serve to present a more detailed explanation of the invention: I Methods a.) Friction coefficient The experiments for the measurement of the friction coefficient were performed on a bottle conveyor under the following conditions: - 6 glass bottles (0,5 litre) are placed on the test track. Friction force [Fz] is constantly measured via an electronic scales with A/D converter. - Spraying of the conveyor with a 0,3 wt. % lubricant solution. 28 - The coefficient friction force [Fz] / weight of bottles [FN] represents the friction coefficient Ful which expresses the lubricity. Speed of the conveyor: approx. 0,4 m/s. - Phase time: 40 sec. spraying / 60 sec. non spraying Spraying performance per spray nozzle: approx. 4 litre / h Furthermore, the products were tested with hard water (16°dH) according to the provisions of DIN 53 902 and tested in completely desalinated water. The variance is a measure for the uniformity of lubricity or friction, respectively on the conveyor belt installations (tracks or chains), being determined from the noise of the friction coefficient measurements. A decreasing variance value relates to a more uniform lubrication on the tracks or chains. The time when the noise of the friction of the coefficient measurement is at a constant level indicates the starting point for transporting the beverage packings on the conveyor due the formation of uniform lubricating film. b.) Water compatibility The compositions to be applied according to the invention show an excellent water compatibility, which can be shown by the performed turbidity measurements (Nephelometer). Herewith, the regular removal of waste, which develops because of the reaction of ions, like sulphate, phosphate and carbonate, with the lubricant solution, can be prevented. For this propose 0,3 wt. % use solutions were measured over a period of 7 days (168 hours). These experiments were performed in the following water conditions: Content Concentration [mg/L] Sodium sulphate (Na2SO4) 148 Sodium chloride (NaCl) 165 Sodium hydrogen carbonate (Na HCO3) 138 Calcium chloride (CaCl x 2 H2O) 275 The water compatibility is expressed in FNU (Formazine nephelometric units). 0 to 1 FNU = clear 1 to 10 FNU = weak, opalescent 29 10 to 50 FNU = turbidity 50 to > 100 FNU = strongly turbidity c.) Foam behaviour The foam behaviour was calculated according to the following method: 100 ml of the use solution (0.3 %) was transferred into a 250 ml measuring cylinder. Thereafter it was shaken 30 times during 30 seconds and after a further 20 seconds the volume of the foam above the 100 ml mark was read off. d.) Material compatibility PET The material compacibility of the mixture according to the invention as well as a comparative example was examined in a test. For this, the following equipment was needed: Environmental camber: in each case 20 new PET bottles (1.5 L) in crates, CO2-cylinder with fitting reducing valve, attachment for filling of the bottles with CO2, separate manometer for testing the bottles with regard to CO2; The tests were executed in the following manner: At first, the bottles were filed with 1.5 L VE-water, thereafter 3.0-3.1 bar CO2 was led into the bottles via an attachment. Then the quantity of CO2 was dissolved into the water by means of shaking. All CO2 was considered to be dissolved only after the test manometer indicated 0 bar. 1.) The bottles were now dipped shortly into concentrated belt lubricant (BSM) (~ 2 cm) and thereafter allowed to stand for 24 hours. 2.) Thereafter the bottles were filled in crates and allowed to stand in a climatic cabinet at 38 °C and 85 % relative humidity for 6 days. As reference a bottle was taken along in each crate which was not dipped into BDM. At the end of the test a visual estimation was made. Here, 5 categories are distinguished. O: No damages 30 A: Minor damages B: Moderate, superficial cracks C: Multiple, moderately deep cracks D: Multiple, deep cracks 31 From the above table it can be seen that each of the lubricant concentrates according to the present invention shows at least comparable, most embodiments an enhanced lubricity compared with lubricant concentrates according to the state of the art. Additionally, they are stable as clear solutions and provide more uniforms lubrication on tracks and chains of feed and conveyance installation in food industry due to the improved variance. 33 We Claim t 1.
