Definitions

  • the present invention relates to lubricant compositions, and more specifically to lubricant compositions for use in lubricating the tracks which convey bottles, cans and similar containers and packages for beverages and other foodstuffs from one station to another in a packaging plant.
  • Lubricant compositions which are currently used for lubricating and cleaning conveyor track are generally of three main types:
  • compositions based on fatty acids (i) compositions based on fatty acids
  • compositions based on phosphate esters are based on phosphate esters.
  • a problem encountered with these lubricant compositions is that many known formulations are aggressive to the colouring pigments used to label the surfaces of the containers, particularly steel and aluminium cans used in the beverage industry.
  • the printed matter printed on the surface of the containers has a tendency to leach into the lubricating compositions thereby fading or distorting the printed matter and giving rise to containers unacceptable to customers.
  • Only a few lubricant compositions have been developed with acceptable container-compatibility properties.
  • One is Superloob NF, an oleic acid soap-based formulation sold by Diversey Corporation.
  • Another Dicolube 95, which is a product described in EP-A-137057.
  • a further problem 'encountered with the conveyor track is the need to keep the conveyor and containers as free from microbial contamination as possible. This is especially important where soil spillage occurs, for example spillage of beer, orange juice and cola.
  • a lubricant composition for use in lubricating conveyor track can be produced which has biocidal properties and does not leach the printed matter printed on the surface of the containers transmitted on the conveyor track.
  • a concentrate which, upon dilution with water, forms a biocidal lubricant composition for use as a lubricant for conveyor track.
  • the concentrate comprises the following components: (a) a phosphate ester of general formula (I)
  • Component (a) is typically present in the concentrate in amounts up to 20% by weight, based on the total weight of the concentrate. If the amount of phosphate ester is too great, it becomes difficult to bring into an acceptable pH range. Preferably, component (a) is present in an amount from 2 to 5% by weight, based on the total weight of the concentrate, more preferably around 8% by weight.
  • Component (b) is preferably a quarternary ammonium compound of general formula (II) R 2 R 3 R 4 R 5 N + X- in which R 2 is an aromatic group such as an arene or alkyl . arene group, preferably a benzyl group; R 3 is a C 12 to C 18 straight chain alkyl group; R 4 and R 5 are the same or different and are H or a C 1 to C 4 linear or branched saturated alkyl group, preferably H, methyl or ethyl; and X- is any suitable counter ion such as halide.
  • component (b) comprises a compound of formula (II) R 2 R 3 R 4 R 5 N + X- in which R 2 is an aromatic group such as an arene or alkyl . arene group, preferably a benzyl group; R 3 is a C 12 to C 18 straight chain alkyl group; R 4 and R 5 are the same or different and are H or a C 1 to C 4 linear
  • This compound is available commercially under the trade name Empigen BAC from Surfachem or Albright and Wilson.
  • the compound is also available from Hoechst, Cargofleet Cochrane and Keane, British CECA and Akzo under the trade names Dodigen ACX, Caflon BCQ50, Benzalkonium chloride 50%, Noranium DA50 and Arquad B50 respectively.
  • component (b) is present in an amount from 2.5 to 5% by weight, based on the total weight of the concentrate. If the amount of the quarternary ammonium compound is too low, negligable biocidal activity is obtained. Too high a concentration will affect adversely the container compatibility of the composition.
  • the identity of the base in component (c) of the concentrate is not critical provided that adjustment of the pH of the concentrate into the required range can be effected without affecting adversely the properties of the concentrate.
  • an alkanolamine base or an inorganic base of the type MOH, in which M is a metal from Group I of the periodic table is used. Where an alkanolamine base is to be used, this is preferably methanolamine or triethanolamine.
  • the preferred inorganic base is NaOH or KOH.
  • the pH of the concentrate is in the range 6 to 9, more preferably around 8. The pH of the concentrate will affect the lubricity of the diluted product in use.
  • the concentrate further comprises component (d), which comprises a betaine, preferably a betaine of formula
  • betaines are not themselves generally biocidal, incorporation of such betaines in the present concentrate was found to increase the biocidal activity of the quarternary ammonium compound.
  • Preferred betaines are commercially available as Empigen BB, or Genamin KBE-X, sold by Hoechst.
  • the betaine is typically present in the concentrate in an amount of up to 10% by weight, based on the total weight of the concentrate.
  • the ratio of betaine to quarternary ammonium compound is in the range 1:4 to 4:1, preferably around 1:1.
  • the concentrate further comprises component (e), which comprises a sequesterant such as EDTA.
  • component (e) comprises a sequesterant such as EDTA.
  • the presence of the sequesterant is useful in hard water areas so as to form complexes with metal ions such as calcium ions which would otherwise tend to precipitate components of the concentrate.
  • the sequesterant is present in an amount of up to 10% by weight, based on the total weight of the concentrate, preferably up to 5% by weight.
  • Hydrotopes may also be present in the concentrate primarily to impart stability to the formulation.
  • a typical hydrotope is urea, which is preferably present in an amount of around 15% by weight, based on the total weight of the concentrate.
  • the lubricant composition should be able to eliminate or at least control the level of microbial contamination on the slats and undersides of the conveyor.
  • the components of the concentrate which forms the lubricant composition and their respective amounts are selected to achieve a lubricant composition which is biocidal. Some routine experimentation may be required to optimise this property of the concentrate. For example, it is advantageous not to use a high ratio of betaine to quarternary ammonium compound. Preferably the ratio of betaine to quarternary ammonium compound should be less than 1.
  • the lubricant composition gives at least a 5 log reduction in a BS3286 test with a contact time of 30 minutes. Preferably, at least a 2 log reduction is achieved in accordance with the surface test described herein.
  • the lubricant composition should be biocidal to at least pseudomonas bacteria such as Pseudomonas aeruginosa, which is capable of forming a slime between the knuckles of the conveyor. This slime is unslightly, a source of unpleasant smell and potential source of product contamination.
  • they should preferably also be able to eliminate or at least control growth of yeast and/or listeria. Yeast can be a problem in a brewery environment whereas listeria can be a problem in a diary environment.
  • the lubricant composition is biocidal against pseudomonas, listeria and yeasts.
  • the concentrate is made up to 100% using water, preferably soft or softened water. Any conventional formulation technique may be used to make up the concentrate and the order of addition of the components is not particularly critical. Usually the base is added to the phosphate ester and the quarternary ammonium compound is added last.
  • a lubricant composition for use as a lubricant for conveyor track.
  • the lubricant composition comprises a concentrate as defined above, diluted in water in the range 0.1 to 5%, preferably 0.5 to 2% (volume/volume). Water used for the dilution is preferably soft or softened.
  • the exact dilution of the concentrate depends on factors such as the speed of the conveyor track, the type of package or container being carried by the track, the total loading on the conveyor track and the amount of soiling caused by spillage.
  • Dilution of the lubricant concentrate is normally performed at a central dispenser, and the diluted lubricant composition is then pumped to spray nozzles at the point of use.
  • the conveyor track There are some areas of the conveyor track that require very little lubricant. Typically these are the zones before the filler and before the pasteuriser. In these regions secondary dilution is often employed. Lubricant is likely to be at its highest use concentration at and after the filler.
  • the lubricant solutions are typically sprayed onto the conveyor from fan jet nozzles placed at the start of each length of track.
  • secondary spray jets may be positioned along the length of the track.
  • timers are employed to vary the dosing rate. Typically, on and off times will be between 10 and 90 seconds. Off times will not always equal on times. Also it is likely that throughout a plant timer settings will vary. In some applications, a final water wash jet will be placed at the end of a bottle/can filling track. This will wash residues of lubricant from the package before crating and dispatching.
  • the present invention is illustrated by the following Examples.
  • Example 1 shows the effect of various formulations on listeria and pseudomonas in the presence or absence of milk soil.
  • the results are presented as a log reduction in the number of viable cells comparing bacterial cultures before and after contact with the lubricant composition in accordance with the modified BS3286 test described in further detail below.
  • the formulations of Examples 1 and 2 are not particularly effective against listeria. This may be explained by the relatively extreme pHs of these formulations. However, these Examples do show a favourable pH range of about 8 to 10 for effectiveness against pseudomonas.
  • the effectiveness of the formulation of Example 14 is apparently reduced because of the relatively high ratio of betaine to quarternary ammonium compound.
  • the biocidal activity tests described above were carried out in accordance with BS3286 with a single modification.
  • the BS3286 test involves preparation of a suspension of the microorganism for evaluation and the suspension is added to the composition to be tested. Following elapse of a chosen contact time, 1 ml of the mixture is added to a neutraliser solution so as to neutralise the microbicidal effect of the composition being tested. A sample of the neutralised mixture is plated to determine the microorganism concentration remaining.
  • composition of the neutraliser used in the tests described in the present specification was modified so as to be effective against the range of lubricant compositions tested.
  • the neutraliser was made by mixing soy lecithin (30 g), Tween 80 (100 g) and water (500 ml) so as to suspend the lecithin. To this suspension was added sodium thiosulphate (5 g), histidine (1.0 g), Na 2 HPO 4 at 0.2 M (144 ml), NaH 2 PO 4 at 0.2 M (56 ml) and water to make 1000 ml. This mixture was autoclaved at 121°C for 15 minutes and mixed whilst still hot to resuspend the Tween 80.
  • a suspension of Pseudomonas aeruginosa (NCIMB) 10421 was prepared by innoculating Tryptone Soya Broth (OXOID CM 129) (150 ml) with a loopful of culture from a 24 hour old slope. After stirring at room temperature for 16 to 18 hours, 40 ml of suspension was removed, spun, washed and resuspended in phosphate buffer (KH 2 PO 4 , 0.1 M and distilled water (500 ml adjusted to pH 7.0 ⁇ 0.1 and made to 1000 ml) to give a cell count of approximately 10 9/ml. The sterilised stainless steel discs were prepared and covered with the suspension and left for 1 hour to allow initial attachment of the bacteria. The suspension was replaced with peptone growth medium
  • Formulations in accordance with Examples 6 and 15 were subjected to the surface test with a contact time of 30 minutes using a 1% solution of the concentrate in water.
  • a log reduction under the modified BS3286 test of 2.82 was found for the formulation of Example 6 and a log reduction of 2.5 was found for the formulation of Example 15.
  • the lubricity and durability of the lubricant composition was measured on a pilot test track, approximately 19 cm wide by 240 cm long.
  • the track comprised a slat conveyor manufactured of 304 stainless steel and was operated at a speed of 60 cm per second. Friction measurements were measured with a 0-2 kg load cell manufactured by Poiden controls. The output from the load cell was connected to a variable speed strip chart recorder, permitting measurements of coefficient of friction (u) verses time. A constant load, consisting of 4 filled bottles connected to the load cell by a loop of nylon thread, was utilised in these experiments.
  • Lubricant compositions were applied in spurts on the test track via a feed pump, through a fan spray nozzle. The pump and nozzle could be adjusted to vary both the frequency of the spurts and the volume of material delivered. In each case a solution volume of 100 ml/minute was achieved with a spurt rate of 13/minute.
  • the pilot test track was also used to meausre the durability of the lubricant compositions. This was accomplished by replacing the intermittent stream of lubricant applied to the track with a constant steam of water. At the same time 16 filled bottles (total weight 14.5 kg) were placed on the track to increase the wear rate. The time required for the coefficient of friction to increase from the lubricated equilibrium value to the original friction value represented the durability of the lubricant. The greater the time, the better the durability.
