Definitions

  • the invention relates to bio-active foams, formulations, manufacture thereof and uses therefor.
  • the foams may be used in cleaning and/or removing spills of inks, dyes, organic matter such as vegetable and/or animal oils and fats, hydrocarbons and paints in the printing, graphics and manufacturing industries and in domestic and/or industrial food preparation.
  • the invention provides a bio-active foam comprising at least one enzyme so as to assist in the breakdown of substrates such as lipids, oils, fats and/or grease.
  • a foamable aqueous liquid containing a surfactant and an enzyme.
  • a foamable aqueous liquid product comprising a stabilising agent, a surfactant, optionally a viscosity modifier, an enzyme and optionally a preservative.
  • the foamable aqueous liquid product does not have to, and preferably does not, contain any organic solvents.
  • the present invention is concerned with the use of an aqueous liquid-based foam carrier for the carriage of a bio-active enzyme.
  • the foam advantageously acts to hold onto the substrate where the foam is applied thereby improving efficiency of targeting.
  • the foam provides a gas/liquid environment above the substrate surface so as to enhance the rate of enzymatic degradation of specific organic species on the substrate.
  • the aqueous liquid component is water and more preferably distilled water. The water acts to solubilise/disperse the various components of the foamable liquid.
  • the stabilising agent is preferably a fatty acid.
  • Suitable examples of fatty acids include stearic acid and/or sodium dodecyl sulphate (syn. lauryl sulphate).
  • the function of the stabilising agent in the foamable aqueous liquid is to stabilise the foam once it has been formed with the help of the surfactant component.
  • Those products suitable for use as a fatty acid must also contain a base so as to neutralise the fatty acid(s) whereby salts/soaps are formed.
  • the base is triethanolamine or another triolkanolamine.
  • the product may optionally contain an acid, base or buffer as a pH modifier.
  • the surfactant is a non-ionic surfactant which may optionally include an anionic surfactant; more preferably the non-ionic surfactant is a polyoxyethylene such as BrijTM, available in the UK from Aldrich Chemical Company.
  • Suitable surfactants which are anionic for example includes sodium n-dodecyl sulphate or lauroylsarcosine sodium salt.
  • Anionic surfactants are known to remove carbohydrate and protein type soils, whereas non-ionic surfactants are especially useful in removing greasy and oily food soils. Therefore, one embodiment of the invention is a mixture of surfactants to clean and remove complex soil types found on food preparation work surfaces and kitchen utensils.
  • the surfactant not only aids in the dissolution or dispersion of the soil but also aids in the initial foaming of the aqueous liquid and is useful in stabilising the foam once it has formed.
  • the viscosity modifier when present, is a gum or the like, such as xanthan gum and is present in preferred embodiments so as to thicken the foamable liquid and thus retard drainage from the formed foam.
  • the preservative when present, is an antioxidant and/or an antibacterial agent and also acts to retard degradation of fats and other organic materials.
  • the foamable aqueous liquid product comprises at least one enzyme preferably selected from the group consisting of catalase, cellulase, cholesterol esterase, esterase, lipase, papain, peroxidase, phosphatase and protease. It will be appreciated that where the foamable aqueous liquid is to be used to remove lipid or ester films from solid substrates or surfaces, Upases and esterases enzymes are of particular utility.
  • the foam is preferably produced by aeration and more preferably by a suitable a propellant or blowing agent, such as a butane/propane mix, for example, A46 hydrocarbon.
  • a suitable a propellant or blowing agent such as a butane/propane mix, for example, A46 hydrocarbon.
  • the foam Once the foam is deposited onto the spill/oil film, it begins to undergo gravitational separation.
  • the aqueous liquid, enzyme(s) and surfactant component parts of the foam drain towards and onto the surface of the spill/oil film.
  • the aqueous medium is unable to penetrate through the film to separate it from the underlying solid surface. It is therefore believed thought that due to the presence and biological activity of the enzymes in the aqueous liquid the enzymatic action starts to "thin" the spill/oil film at the interface, allowing the aqueous liquid to penetrate the oil film and separate it from the underlying solid surface. The process is assisted by the presence of surfactants. As a consequence of the enzymatic action, the film can be lifted from the solid surface in small "crazy paving" type fragments.
  • the film fragments Once the film fragments are separated from the solid substrate they begin to float up (oil being lighter than water) through the aqueous medium and to some degree (if they are small enough) through the lamellae of the foam, so that they are trapped at the gas/liquid interface.
  • the foam is thus believed to act advantageously in several ways: i) as a targeting aid; ii) as a reservoir for the enzyme(s) and surfactant; iii) as a controlled means of dispensing enzyme and surfactant to the oil film surface and; iv) as a trap for the released oil film fragments.
  • the foamable aqueous liquid product is contained within and dispensed from a pressurised container or canister.
  • a pressurised container or canister may be reusable and capable of being re- ⁇ ressurised.
  • the foamable aqueous liquid may be contained within a tank storage vessel and piped/dispensed under pressure from a directing nozzle to the area/ apparatus in need of cleaning.
  • the viscosity of the foamable aqeuous liquid is desirably selected so that the liquid is able to drain from the lamellae of the foamed liquid in a slow controlled manner. If the viscosity is low then the rate of drainage (gravitational separation) will be fast and the foam will collapse quickly.
  • the foamable aqueous liquid has a viscosity in the range 2 to 10 centipoise.
  • the foam is achieved by pressurising the aqueous liquid with a liquified "blowing agent" in a canister.
  • a liquified "blowing agent” in a canister.
  • the liquid blowing agent becomes dissolved in the foam liquid and expands as it gassifies.
  • the blowing agent is uniformly mixed/dispersed with the foam liquid so that bubbles of relatively uniform size are produced from the foamable liquid ideally resulting in a formed foam with a bubble size within a specific size range in order to effect stability of the formed product. If there are a wide range of bubble diameters within the foam this can lead to instability and rapid foam collapse.
  • the bubble size is desirably selected to be quite small e.g.
  • the formed foam has bubbles of diameter within the range of 100-1000 ⁇ m (for example 100-500 ⁇ m, e.g. about 200 ⁇ m) and more preferably the standard deviation is within the range + 10-30% and more preferably still ⁇ 20%.
  • a formulation comprising about 80 to 90 wt.% of an aqueous medium, about 5 to 15 wt.% of a stabilising agent, about 2 to 5wt.% of a base, about 1 to 5 wt.% of a surfactant, about 0.05 to 0.5 wt.% of a viscosity modifier, an enzyme in the range of 0.1 to 1.0 wt.%, and optionally about 0.01 to 0.05 wt.% of a preservative, the formulated product being in the form of a foamable liquid.
  • the formulation may contain up to 5 wt.%, preferably up to 3 wt.% and more preferably up to 1 wt.%, of other additives or components. The percentages of all components add up to 100%.
  • the foam is formed by aeration with a propellant/blowing agent, such as foam 2 to 5 wt.% of a butane/propane mix (e.g. A46 hydrocarbon).
  • a propellant/blowing agent such as foam 2 to 5 wt.% of a butane/propane mix (e.g. A46 hydrocarbon).
  • the preferred concentration of enzyme within the formulation varies between 0.1 and 1.0% by weight and its selection is dependent on a user's requirements.
  • the invention therefore includes a liquid having the characteristics of a foamable liquid obtained by the above method.
  • steps (i) to (v) may be performed sequentially as steps (i) to (v), simultaneously or in a variety of combinations either separately or in combination, the sequences of which is not intended to limit the scope of the method.
  • the resulting mixture when the resulting mixture is completed, it is provided in a container from where it may be dispensed under pressure.
  • the foamable liquid is aerated in order to form the foam and that aeration may be by agitation or by passing an appropriate blowing agent/propellant therethrough, preferably under pressure.
  • a foamable liquid as hereinbefore described for use as a cleaning product in the printing and graphic arts industries.
  • the foamable liquid of the present invention is of particular use where it can be used to "wash-up” i.e. clean print machine rollers and to clean small scale spill residues of oil-based and quick-set inks in printing works.
  • the foamable liquid of the present invention does not have to contain any volatile organic solvents and therefore may be safe for use in the workplace within the terms of the European Union Volatile Organic Compounds (VOC) Directive and the Environmental Protection Agency and OSHA regulations in the United States.
  • VOC European Union Volatile Organic Compounds
  • the foam clean up system advantageously constitutes a completely solvent-free printing system.
  • a foamable liquid as herein before described for use in the food preparation and manufacturing industries.
  • the foamable liquid and formed foam are non-toxic and non- hazardous when in use.
  • the foam may also be used as an industrial and/or domestic cleaning agent in the manufacture, retail and preparation of foods as a de-greasing agent for surfaces such as, for example, counters, floors and walls in addition to use as a cleaning agent in conventional and microwave ovens.
  • the foams are of particular use in de- greasing/removing oil films from food preparation equipment and in the removal of solid oil residues, at room temperature from worktops and food preparation surfaces.
  • a foamable liquid as herein before described for use in removing lubricating and diesel oil-spill residues, grease residues and non-dried, oil-based paint residues after small scale spills.
  • the foams are of particular use in removing such spill/residues from flat and porous surfaces.
  • the viscosity modifier (when used) is dispersed in the aqueous liquid under action of mild heat.
  • the surfactant may be added at the same time or after the viscosity modifier has dispersed.
  • the surfactant if solid, is allowed to melt and the stabilising agent and base added to the mixture with stirring.
  • the enzyme(s) may be added and optionally the preservative may be included in the mixture.
  • the mixture can then be dispensed into appropriate containers for subsequent use.
  • Xanthan gum (1.2 g) is dispersed completely in water (845 ml) by mixing vigorously. The mixture is then heated to a temperature of about 60°C. Next, Brij 35TM (21.5 g) is added and mixed until completely melted. Subsequently, stearic acid (65 g) is added and mixed until it has completely dissolved. The mixture is then warmed to about 75°C and triethanolamine (37 ml) poured in and mixed. Then lauryl sulphate (29g) is added for about 0.5h until all the components have combined thoroughly. The mixture is cooled to about 30°C and BHT (0.2 g) is added. The enzyme lipase (0.5 wt. %) derived from porcine pancreas is then added and entire mixture is mixed well to dissolve the enzyme. During the preparation, mixing is carried out at a low speed in order to minimize foaming.
  • the final mixture is cooled to 20°C and dispensed into appropriate vessels/cans.
  • a blowing agent is used (A46 hydrocarbon at 3.2 wt.%) to act as a propellant.
  • the foamable liquid preparation is contained and dispensed in pressurised canisters or alternatively dispensed into larger refiUable re-pressurisable canisters.
  • the foamable liquid is contained within a tank and piped under pressure to dispensing nozzles on, for example, a large printing machine.
  • Example 2 The composition of Example 2 was prepared in the same way as Example 1 but the enzyme was an esterase (0.5 wt. %), derived from porcine liver.
  • lipase For the removal of thin vegetable oil films, the addition of 0.5% by weight lipase is more efficient in terms of speed of removal and percentage removal of the film, than 0.5%) by weight esterase.
  • esterase does have value in specific applications (eg. certain mineral oils) it is envisaged that lipase will be adopted as a standard enzyme for the application of the foam to most commercial-scale cleaning applications.
  • ink film was applied to the rough sides of frosted microslides by spreading a thixotropic ink onto its surface. The ink was spread onto the slide so that the fissures on the rough surface filled up with the ink and produced an even layer was produced . The thickness of the ink layer was approximately 20 ⁇ m. Experiments were performed within a 25 by 12.5 cm square polypropylene box. Ink coated slides were supported so that they rested approximately 25 mm above the base of the box. In this way intimate contact with the foam was achieved whilst avoiding contact with the solution in the bottom of the box which results from drainage from the foam.
  • the video camera was connected to a Joyce/Loebel Magiscan image analyser to perform the densitometry measurement.
  • the results are tabulated below. Values are given as transmittance so that black i.e. no transmittance would have a value of 0 whereas white i.e. complete transmittance would have a value of 100. Thus, the higher the densitometer transmittance value the more effective the cleaning.
  • Figure 1 B a control microslide ( Figure 1 B) covered with an ink film which received no treatment.
  • Figure 1 A illustrates an ink film coated microslide to which the foam formulation of Example 1 without the presence of an enzyme was applied
  • Figure 1C illustrates an ink film coated microslide to which the foam formulation of Example 1 including an enzyme ( 0.1% lipase) has been applied.
  • Example 4 The results demonstrate that addition of the enzyme to the foam formulation greatly improves the ability and efficacy of the foam to lift ink spills compared to foam without an enzyme. In addition, following treatment with Example 1 foam with enzyme the residual ink film on the microslide was much "looser” and more amenable to being washed off in a water stream.
