Definitions

  • the present invention relates to a surface coating producing enhanced ultra violet light protective capacities.
  • the coating of the invention finds use, inter alia, in the food and beverage industries in coating containers whose contents are sensitive to degradation resulting from exposure to ultra violet (UV) light.
  • UV ultra violet
  • Ultra violet light is well known for its capacity to cause degradation to a number of materials both natural and man-made.
  • the present invention is concerned with the effect of ultra violet light of certain frequencies on foodstuffs. Beer, in particular is known to be sensitive to the effects of UV light.
  • off odours known variously as light strike or skunky flavours; this last term referring to the resemblance of the off odours/flavour to the odour of the North American skunk.
  • MBT 3-methyl-2-butene-1-thiol
  • the wavelengths of light responsible for the development of light struck flavour lie generally in the region 350-500nm.
  • containers impervious to UV light Such containers include metal cans and dark brown glass bottles. This need to use opaque containers has limited the opportunities available to those concerned with the marketing of beer products. It has been found possible to replace the whole of the hop in beer production with hop products to circumvent the production of iso-alpha acids during boiling. These treatments however are not entirely satisfactory as the iso-alpha acids are responsible for much of the characteristic bitter flavour of the beer. Accordingly, although beer produced in this way is easier to store the product is less desirable to drinkers. The process results in a beer product having a very narrow flavour range, which is considered a less attractive product by many drinkers.
  • One of the methods used to reduce UV radiation exposure in foodstuffs stored in glass is the use of green glass incorporating metal oxides; specifically, chromium and nickel compounds are used.
  • chromium and nickel compounds are used.
  • the use of either chromium or nickel compounds in foodstuff storage containers is undesirable both from a cost and an environmental point of view.
  • Figure 1 illustrates the absorbance and transmission spectra measured over the relevant range for a number of current glass beer containers as sold in Australia. Significantly, with the exception of the well-known amber glass product all of the products have transmission of >60% in the critical wavelength regions 380-400nm.
  • the present invention proposes a coating to be applied to a surface that enhances the UV absorbance of the coated surface without a concomitant requirement for the surface to be darkly coloured.
  • composition for coating a substrate said composition including:
  • an inorganic oxide material selected from the group consisting of zinc oxide, cerium oxide and titanium dioxide;
  • the minor portion of inorganic oxide material is dispersed in the major portion of the base carrier material as a particulate dispersion to thereby create a coating capable of absorbing UV light and transmitting visible light.
  • the minor portion of the inorganic oxide material is dispersed as a dispersion of ultra fine particles in the polymer base.
  • a dispersion of ultra fine zinc oxide particles produces a coating having a wide band absorbance band in the UV range.
  • a dispersion of ultra fine particles are particles of a sub micron size. At an appropriate particle size the inorganic oxide particles become substantially translucent. Typically, milling can produce particles of this size.
  • the technology requires the production of ultra fine particles as described in international patent application no WO 97/17406.
  • a process that includes comminuting the oxide in the presence of a liquid, the liquid being constituted by or including a component having available hydrogen and/or oxygen ions produces ultra-fine particles of the oxide.
  • the liquid may be an alcohol ester, a hydrogenated ester or a polymer containing hydroxyl or hydrogen group(s).
  • the process results in a stable dispersion that does not aggregate or agglomerate. More usefully for the present invention the milling process results in a particulate material, which has a clear transparent appearance. This clear characteristic is carried through to the coating used in the present invention.
  • the coating of the invention has UV absorbance properties whilst being of a clear colourless appearance- an attractive commercial proposition.
  • the inorganic oxide is milled in any one of capric caprylic triglyceride, methyl ethyl ketone (MEK), ethyl ethoxy proprionate (EEP), or propylene glycol methyl ether acetate (PGMA).
  • MEK methyl ethyl ketone
  • EEP ethyl ethoxy proprionate
  • PGMA propylene glycol methyl ether acetate
  • the major portion of the base carrier material is in the range 90-99 wt.% of the composition and the minor portion of an inorganic oxide material is present in the range 1- 10 wt.%.
  • the composition of the invention may, in addition to the components outlined above include a number of further additives.
  • the addition of iron oxide increases the absorbance of the coating around the 390nm mark into the red end of the visible spectrum. In some cases this type of coating may be preferred by end users for aesthetic or other reasons.
  • the composition may include up to 2 wt.% of iron oxide.
  • Optical brighteners have the advantage of absorbing light from the UV region and re- emitting the light in the visible region.
  • the addition of such materials to the composition has the effect of enhancing the UV protective features of the composition.
  • a suitable optical brightener might be diethylamino-4-methyl coumarin (DEMAC). More preferably still the optical brightener would be commercially available UV brighteners such as those sold under the name Uvitex OB as supplied by Ciba Geigy.
  • the composition may include up to 2 wt.% of optical brighteners in the formulation.
  • Uvitex OB is a particularly preferred optical brightener.
  • composition of the invention may additionally include dispersants to encourage an even distribution of the inorganic material within the polymer base.
  • the base carrier material is a polyurethane polymer material.
  • Such materials can be used to provide a thin film coating on glass.
  • a coating suitable to achieve the aims of the invention would be laid down as a wet film of up to approximately 60 ⁇ m thickness that corresponds to a dry thickness of up to approximately 30 ⁇ m thickness.
  • Alternative carrier materials include polyethylene and long chain fatty acids such as oleic or stearic acids. It will be appreciated that using an increasing loading of inorganic oxide material and optical brightener can reduce the coating thickness. Similarly, in a thicker coating the loading of inorganic oxide material and optical brightener may be reduced.
  • the coating is applied as a cold end coating in the manufacture of glass bottles, with a coating thickness of perhaps as little as 0.1 ⁇ m.
  • the application of the coating of the present invention can therefore be incorporated into the glass manufacturing process. In such a way a glass manufacturer is able to incorporate the composition of the invention into the product with minimal interruption of the glass manufacturing process. Thus, the cost of creating the coating on the product can be minimised.
  • the invention is constituted by a vitreous surface coating of 15-25 ⁇ m thickness containing 5% ZnO and approximately 0.1% Uvitex which has been found to block 85% of the light at 400nm, and in a second preferred embodiment a vitreous surface coating of 15-25 ⁇ m thickness containing 5% ZnO and approximately 0.5% Uvitex which has been found to block 94% of the light at 400nm
  • the present invention provides a process for creating a coating capable of absorbing UV light and transmitting visible light on a surface said process including the steps of milling an inorganic oxide material selected from the group consisting of zinc oxide, cerium oxide and titanium dioxide and adding this to a base carrier material to form a dispersion containing a minor portion of the inorganic oxide a major portion of the base material together with a minor portion of an optical brightener.
  • the inorganic oxide base is milled as a paste in a liquid, the liquid being constituted by or including a component having available hydrogen and/or oxygen ions.
  • the liquid may be an alcohol ester, a hydrogenated ester or a polymer containing hydroxyl or hydrogen group(s). The process results in a stable dispersion of the inorganic oxide that does not aggregate or agglomerate.
  • the inorganic oxide is milled in any one of capric caprylic triglyceride, methyl ethyl ketone (MEK), ethyl ethoxy proprionate (EEP), or propylene glycol methyl ether acetate (PGMA).
  • MEK methyl ethyl ketone
  • EEP ethyl ethoxy proprionate
  • PGMA propylene glycol methyl ether acetate
  • composition of the invention therefore represents a UV absorbing coating that is adapted for use on a number of substrates and in a wide range of situations.
  • the composition is thought to be particularly useful as a coating to be applied to food and beverage containers.
  • Figure 1 indicates the UV absorbance of commercially used glass beer bottles
  • Figure 2 illustrates the UV absorbance of a composition containing BM5050 and various loadings of ZnO milled in PGMA
  • Figures 3a, 3b and 3c represent the UV absorbance of a composition containing BM5050 and various loadings of ZnO milled in PGMA together with various loadings of optical brightener.
  • the UV absorbance of a number of compositions was tested. Attention as paid to the UV absorbance of the thin coating films of various compositions in the critical UV-A (290- 320nm) and UV-B (320-400nm) wavelengths. For purposes of comparison the absorbance of the compositions can be tested against those for commercially available glass products used for beer shown in Figure 1.
  • Zinc Oxide was milled to an ultra fine state in a paste of propylene glycol methyl ether acetate (PGMA) together with a dispersant (Solsperse 20000).
  • PGMA propylene glycol methyl ether acetate
  • Solsperse 20000 a dispersant
  • the milled product was dispersed into a moisture curing polyurethane resin BM5050 at loadings of 2, 4 and 5 % and laid down as 40 ⁇ m wet films on microscope slides. Glass microscope slides were used instead of more typical quartz slides as the glass more accurately represents the glass typically used in beer production and has a similar UV absorbance profile.
  • UV absorbance was tested across the range 190nm -800nm covering the UV and visible spectra. Absorbance spectra for the resulting coating are shown in Figure 2. Good absorbance was observed for all films in the UV region, with even the lowest loading of zinc oxide UV, i.e. 2 wt. % giving an absorbance of 1 , corresponding to 90 % light absorbance.
  • the tests described above include the combining of two separately milled dispersions into the BM5050 polyurethane resin. It is also possible for the optical brightener and the inorganic oxide to be co-milled in the same dispersion with the PGMA and a dispersant.
  • Plaques prepared with the co-dispersed additives were significantly whiter than blank BM5050, and also whiter than those produced with separate dispersions of additives. This effect is illustrated in haze measurements shown below in table 1.
  • the increased whiteness is also responsible for the apparent increase in absorbance noted in these formulations. This increase is, however, due to a larger degree of light scattering i.e. the whiteness.
  • the 24 bottles of wine were layed down in a single layer in a 'staggered' fashion (a 'coated' bottle followed by an 'uncoated' bottle etc.) in a cupboard, approximately 50 cm from a UVA light source (emitting radiation of wavelength approximately 360nm) continually for 21 days.
  • a UVA light source emitting radiation of wavelength approximately 360nm
  • the sensory assessments were performed using triangular difference tests to establish whether significant differences existed between the wine contained in the bottles coated with the UV Protective Coating ('coated') and the wine contained in the bottles without the coating ('uncoated').
  • the tables given by Jellinek were used to establish the level of significance from the number of correct judgements. Jellinek, G. Sensory evaluation of food: etc see top of next page.
  • a panel comprising twenty Institute Staff members with experience in the sensory assessment of wines using triangular difference testing was used for the assessment. Panellists were asked to describe the any differences observed. Four comparisons were made, using a 'coated' and 'uncoated' bottle for each, to give a total of twenty sets of data for each comparison.
  • the bottles used in each comparison were statistically significantly different, to within a level of error of 0.1% in other words, the probability if obtaining such an outcome by chance alone is less than 1 in 1000.
  • the tasters generally considered the wine from the bottles coated with the UV Protective Coating to be more fresh and to exhibit more fruit intensity than the wine from the uncoated bottles.
  • the terms used by the tasters to describe the wine from the bottles without the UV Protective Coating were consistent with the terms commonly used by tasters to describe reduced sulphur compounds in wine. Table 2. Results of sensory assessment - Results obtained for following comparison 3

Abstract

L'invention concerne une composition destinée à revêtir un substrat tel que du verre pour constituer un revêtement de protection contre les UV. La composition comprend une majeure partie de matière support de base, et une partie mineure de matière d'oxyde inorganique sélectionnée dans le groupe constitué par de l'oxyde de zinc, de l'oxyde de cérium et du dioxyde de titane. La partie mineure de matière d'oxyde inorganique est dispersée dans la majeure partie de matière support de base sous forme de dispersion particulaire, afin de produire un revêtement capable d'absorber la lumière UV et de transmettre la lumière visible. En particulier, l'invention tire parti du fait que certains oxydes inorganiques adsorbant l'UV peuvent être broyés à une taille de particules inférieure au micron, à laquelle ils deviennent transparents/translucides en dispersion. L'invention permet ainsi d'obtenir un revêtement transparent aux UV.
