Definitions

  • This invention relates to aqueous lubricant compositions suitable for use in the beverage and food industries.
  • While the present invention has broad applicability to the conveyance of containers it is envisaged to be particularly applicable to the conveyance of glass, plastic, plastic impregnated or coated cardboard, or metal beverage containers on belt or chain conveyors of metal or plastic.
  • the container is of glass a stainless steel conveyor is often used whereas, when the container is of another material, for example of aluminium, or of polyethylene terephthalate (PET) or of polyethylene (PE) the conveyor may be of, for example, of nylon or of polypropylene or an acetal resin.
  • Lubricant compositions are also subject to requirements other than those relating purely to their frictional performance.
  • Some lubricant compositions react with the hardness salts in water to deposit alkaline earth fatty acid salts on the conveyor and on the pipework used to deliver lubricant to the conveyor. This may be alleviated by ensuring that only soft water, for example containing hardness salts equivalent to below 5 ppm CaCO 3 , is used to make up the lubricant or by including an effective amount of a complexing agent, such as ethylene diamine tetra-acetic acid (EDTA), in the composition.
  • EDTA ethylene diamine tetra-acetic acid
  • Some lubricant compositions may tend to cause stress-cracking in the bases of plastic containers, such as PET containers, under conditions of internal pressurisation and/or warming. Using the lubricant compositions of the invention this effect may be reduced.
  • Some lubricant compositions amongst the fatty acid-, fatty amine- and phosphate ester-based compositions have a deleterious effect on print and tend to cause the leaching of printing ink from a print display. Since it is common practice to preprint beverage cans this presents a considerable problem.
  • U.S. patent specification No. 5 747 431 describes an aqueous lubricant composition containing one or more of a specific range of cyclic imidazolines defined by general formula and an amount of an inorganic acid or a carboxylic acid having up to 6 carbon atoms, for example acetic acid, sufficient to render the cyclic imidazoline soluble in water.
  • the quantity of the acid is typically from 0.05 to 10.5% by weight of the concentrate and, if required, additional acid is be added to bring the pH into the required region which is, preferably, from 3 to 8, more preferably from 3 to 6. At such a pH the imidazoline is solubilized by conversion to the acetate.
  • the lubricant composition may also contain an alkylamine carboxylate although this is exemplified in a quantity of only 0.6% wt/wt active raw material relative to 2.0% on an active basis, of the imidazoline.
  • U.K. patent specification No. 2 285 630-A describes an aqueous lubricant composition containing an alkylamine dicarboxylate, a cyclic imidazoline and an alkyl sulphonate anionic surfactant, each defined by general formula.
  • the present invention in its broadest aspect, is based on an aqueous lubricant composition comprising a combination of an amphoteric carboxylate with an imidazoline, the composition having a pH greater than 8, and on the finding that an unexpected degree of reduction in sliding friction obtainable by the use of such a composition, as well as certain other beneficial properties, in the absence of a content of any effective quantity of an anionic sulphonate surfactant, or of any other anionic surfactant.
  • any sulphonate or other anionic surfactant if present, is preferably present in less than 0.2%, particularly preferably less than 0.15% by weight of the composition.
  • cyclic imidazolines are believed to hydrolyse under some pH conditions with ring opening.
  • the present invention encompasses both cyclic imidazolines and the chain compounds corresponding to the cyclic imidazoline hydrolysis products, whether the chain compounds are actually formed by the hydrolysis mechanism or not, or whether they are formed in situ in the lubricant composition or not and the term "hydrolysis product", used hereafter, is intended to encompass all of these alternative possibilities.
  • the present invention provides an aqueous lubricant composition
  • aqueous lubricant composition comprising a combination of (a) one or more alkylamine monocarboxylates defined by the general formula (I) wherein
  • R 3 is an alkyl fatty chain, preferably of coco-distribution.
  • the preferred compounds within Formula (II) for use in the practice of the present invention are: and hydrolysis products thereof.
  • the lubricant compositions of the invention may be in the form of a concentrate, for example containing from 0.1% to 10% by weight, or up to the solubility limit, which may be up to 20% by weight or more, in total and on an active material basis, of the amphoteric alkyl carboxylate and the imidazoline.
  • a concentrate is preferably, but not essentially, produced using naturally soft water, distilled water or softened water to maximise storage stability.
  • the concentrate is further diluted, for example from 0.0005% to 5%, preferably at least 0.005%, preferably up to 2%, in total and on the same basis, of the same compounds. For this further dilution it is found that soft, medium or even hard water may be used.
  • the relative molar proportion of the amphoteric alkyl carboxylate and the imidazoline is preferably from 10:90 to 90:10, particularly preferably from 60:40 to 40:60.
  • the lubricant compositions may contain other constituents, for example a hydrophilic organic co-solvent such as, for example butyl diglycol, monoethylene glycol or isopropyl alcohol, suitably in a concentration of from 1% to 10% by weight, a nonionic surfactant such as an alcohol alkoxylate, suitably in a concentration of 0.1% to 5% by weight and a biocide, suitably in a concentration of from 0.1% to 10% by weight.
  • a hydrophilic organic co-solvent such as, for example butyl diglycol, monoethylene glycol or isopropyl alcohol, suitably in a concentration of from 1% to 10% by weight
  • a nonionic surfactant such as an alcohol alkoxylate
  • a biocide suitably in a concentration of from 0.1% to 10% by weight.
  • the cosolvent may be supplied by using the amphoteric carboxylate in the form of a solution thereof.
  • the pH of the lubricant composition of the invention is controlled at a pH greater than 8.5 for example, desirably, greater than 9. It is preferred that the pH is below 11 and a pH range of from 9.5 to 10.5 is particularly preferred.
  • the imidazoline is, surprisingly, solubilized in the presence of the alkylamine carboxylate. There is no reliance on salt formation to achieve solution in water.
  • the effectiveness of the lubricant compositions may be tested as follows.
  • a number of glass bottles sufficient to give a load of 2000g are placed on a pilot conveyor fitted with a stainless steel track.
  • the bottles are tethered to a force gauge capable of measuring the drag force in grams.
  • Lubricant at a suitable concentration is sprayed onto the track and the track set in motion.
  • Drag Coefficient (U) is calculated as Drag Force/2000 g.
  • a coefficient of less than 0.15 represents good lubrication and higher values represent poor lubrication.
  • Pressurised PET bottles are dipped into a sample of lubricant prediluted to use concentration (typically 1% by weight). After 10 minutes the bottles are removed and placed in an oven at a temperature of 38°C. After 72 hours at this temperature the bottles are removed and are examined visually for signs of stress cracking. A bottle similarly oven treated, which had not been contacted with the lubricant is used as a control.
  • Samples of steel sheet printed with a representative ink are immersed in solutions of the lubricant having up to 10 times normal use concentration. The solutions are held at a temperature of 60°C for 30 minutes and the samples were then removed and examined visually for ink leaching.
  • Example 1 used both the essential components of the invention, the imidazoline was absent from Example 2 and the amphoteric alkyl amine carboxylate was absent from Example 3. A synergic effect is apparent in the composition according to the invention from the results.
  • Example 4 composition was further diluted to 1% in water containing 10ppm sulphate or 10ppm phosphate ions. Both solutions remained clear overnight. This is in contrast to cationic lubricants, such as those based on fatty amines, which tend to become cloudy on standing as a result of the formation of insoluble sulphate or phosphate salts.
  • Example 5 composition was tested in waters ranging from 30 to 250 ppm CaCO 3 of hardness with no observable difference in Drag Coefficient. All the solutions remained clear despite the absence of a chelating agent.
  • lubricant compositions of the invention were found to be compatible with Can Print Pigments and PET.
