RELATED REQUESTS AND PRIORITY CLAIM
[0001] This document claims priority to United States Provisional Patent Application Number 61/705,986, filed September 26, 2012 and United States Patent Application No. 13/760,546, filed February 6, 2013, which descriptions are incorporated by reference in this Application. BACKGROUND
[0002] In 1800, Dr. FW Herschel, from Great Britain, discovered and reported to the academic world a wavelength ranging from 0.7-1000 microns, a little beyond visible light, called infrared, which has strong physical properties and great thermal activity. The natural resonant frequency range of water and living organisms, including man, falls within the infrared range. For example, the 6-18 µm wavelength range is well known to be beneficial to the human body because of its activating and energizing effect on the body. In fact, human skin radiates an infrared wave of 9.36 µm, which is very close to the resonant frequency of a water molecule - and with good reason, since our bodies are about 70% water. Infrared waves may be the safest and most beneficial source of energy available.
[0003] According to the National Center for Complementary and Alternative Medicine (NCCAM), "some CAM practices involve manipulating multiple energy fields to affect health. Such fields can be characterized as true (measurable) or putative (yet to be measured. Practices based on true energy forms include those involving electromagnetic fields (eg, magnetic therapy and phototherapy)." (What is Complementary and Alternative Medicine (October 2008). Retrieved August 31, 2012 from http://nccam.nih.gov/health/whatiscam).
[0004] Bioceramics include ceramics which radiate beneficial infrared waves. Because of their benefits to human health, bioceramics are now used for a variety of purposes, including biomedicine and everyday products. These seek to use the effects of infrared radiation emitted by them including, for example, maintaining food freshness, deodorizing, revitalizing, etc. There is a need, therefore, to develop additional bioceramic compositions and uses thereof that impart additional beneficial effects.

[00019] As used in this document, the singular forms "a", "an", "o" and "a" include plural references unless the context clearly indicates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art. As used herein, the term "comprising" means "including, but not limited to".
[00020] The biological effects of bioceramics are based on the fact that the infrared frequency range is the natural resonance frequency range of water and living organisms. Since a considerable part of living organisms includes water, the resonance frequency of water molecules irradiated from bioceramics can activate the water and affect living organisms.
[00021] This document describes bioceramic compositions comprising from about 45% by weight to about 55% by weight of kaolinite kaolinite (Al2Si2O5(OH)4); from about 5% by weight to about 15% by weight of tourmaline; from about 3% by weight to about 13% by weight aluminum oxide (Al2O3); from about 11% by weight to about 19% by weight silicon dioxide (SiO2); and from about 3% by weight to about 13% by weight of zirconium oxide (ZrO2), wherein the amounts are by weight of the total composition. In one embodiment, the amount of kaolinite in the bioceramic composition is selected from approximately 45% by weight, 46% by weight, 47% by weight, 48% by weight, 49% by weight, 50% by weight, 51% by weight , 52% by weight, 53% by weight, 54% by weight and 55% by weight by total weight of the composition. In another embodiment, the amount of kaolinite ranges from about 45% by weight to about 50% by weight of the total weight of the composition. In yet another embodiment, the amount of kaolinite ranges from about 51% by weight to about 55% by weight of the total weight of the composition. In another embodiment, the amount of kaolinite ranges from about 47% by weight to about 53% by weight of the total weight of the composition. In one embodiment, the largest size of any particle in the bioceramic composition ranges from about 0.5 µm to about 25 µm. In another embodiment, the largest size of any particle in the bioceramic composition ranges from about 1 µm to about 20 µm. In yet another embodiment, the largest size of any particle in the bioceramic composition ranges from about 2 µm to about 15 µm.
[00022] As used herein, the term "tourmaline" retains its known meaning in the art of minerals and precious stones. For example, Tourmaline, according to the website "The Mineral & Gemstone Kingdom" (http://www.minerals.net/tourmaline_chemical_formula.aspx), is "a group of isomorphic minerals with an identical crystal structure. Each member of the Tourmaline group has its own chemical formula due to small differences in elemental distribution," according to language taken directly from the site.
[00023] A simple generic formula for the Tourmaline group is: X1Y3Al6(BO3)3Si6O18(OH)4 where: X = Na and/or Ca and Y = Mg, Li, Al and/or Fe2+
[00024] This creates the formula: (Na,Ca)(Mg,Li,Al,Fe2+)3Al6(BO3)3Si6O18(OH)4
[00025] In some less common varieties, Al can be replaced by other elements.
[00026] For example, in Uvita, Al is partially replaced by Mg.
[00027] This expands the formula to: (Na,Ca)(Mg,Li,Al,Fe2+)3(Al,Mg,Cr)6(BO3)3Si6O18(OH)4
[00028] Buergerite contains three S atoms and one F atom, in place of the OH radical. A Buergerite molecule also contains an iron atom that is in a 3+ oxidation state.
[00029] This further expands the formula to: (Na,Ca)(Mg,Li,Al,Fe2+,Fe3+)3(Al,Mg,Cr)6(BO3)3Si6O18(OH,O, F)4
[00030] Finally, the site provides the chemical formulas of individual members of the Tourmaline group:
[00031] Schorlite: NaFe2+3Al6(BO3)3Si6O18(OH)4
[00032] Dravite: NaMg3Al6(BO3)3Si6O18(OH)4
[00033] Elbaite: Na(Li,Al)3Al6(BO3)3Si6O18(OH)4
[00034] Lidicoatite: Ca(Li,Al)3Al6(BO3)3Si6O18(OH)4
[00035] Uvita: Ca(Mg, Fe2+) 3Al5Mg(BO3)3Si6O18(OH)4
[00036] Buergerite: NaFe3+ 3Al6(BO3)3Si6O18O3F

[00047] In relation to an article that includes a metallic substrate, the bioceramic composition can be applied to the metal in a liquid/fluid form by any process known in the metal processing art. For example, the bioceramic composition can be incorporated into a liquid/fluid vehicle such as, but not limited to, paint, sealant, varnish and the like, and applied to at least a portion of the surface of the metal substrate.

The bioceramic composition may also be incorporated into or on the surface of a beverage container (e.g., cans, bottles or the like) or within or on a label or tag to be affixed to a bottle or can containing beer or other beverage to be treated. Water or any other beverage can also be treated with the bioceramic composition in a similar way.
[00055] The following non-limiting examples serve to further illustrate the present invention. EXAMPLES
[00056] Example 1: Preparation of a powdered bioceramic composition.
[00057] Kaolinite is extracted on the outskirts of the city of Parintins, in the State of Amazonas, Brazil. The city is located in the Lower Amazon Region (coordinates: latitude: 2° 37' 42" south / longitude: 56° 44' 11" west of Greenwich, 50 m above sea level).
[00058] The extracted kaolinite is washed with hydrogen peroxide (H2O2) and allowed to dry. The dried kaolinite is then finely ground and mixed with tourmaline; aluminum oxide (Al2O3); silicon dioxide (SiO2); and zirconium oxide (ZrO2) until a homogeneous mixture is obtained. The resulting bioceramic composition contains 50% by weight of kaolinite, 10% by weight of tourmaline, 18% by weight of aluminum oxide, 14% by weight of silicon dioxide and 8% by weight of zirconium oxide. The electron microscopy image in Figure 1 demonstrates that the composition includes bioceramic particles smaller than 1 micron.
[00059] Example 2: Fabric impregnation
[00060] A textile substrate which includes 88% by weight of polyamide and 12% by weight of elastane was obtained. A bioceramic composition prepared according to the method of Example 1 was incorporated into a plastisol paint in an amount of 10% by weight and mixed. The mixture was applied to the textile substrate using a traditional screen printing process. Figure 2 is a graph of the spectral transmittance of the bioceramic composition deposited on the textile substrate. Figure 3 is a graph of the spectral transmittance of the bioceramic composition alone. The numbered peaks in Figures 2 and 3 indicate that the bioceramic composition absorbs infrared radiation.
[00061] Example 3: Freshness of beverages
[00062] A beverage holder including closed-cell extruded polystyrene foam was obtained. A bioceramic composition prepared according to the method of Example 1 was incorporated into a plastic-based paint in an amount of 10% by weight of the paint composition and mixed. The mixture was applied to the inner surface of the beverage holder. An extruded plastic composition containing the bioceramic composition in an amount of 10% by weight of the plastic was also prepared using a traditional extrusion process. The extruded plastic composition was placed in the bottom of the beverage holder.
[00063] A 10 mL sample of beer that had not yet been exposed to the bioceramic composition in the beverage holder was analyzed using gas chromatography-mass spectrometry (Gas Chromatography-Mass Spectrometry - GC-MS) (Figure 5). A comparison of Figure 5 with Figure 6 (mass spectrum of furfural) revealed the presence of peaks corresponding to furfural in the beer sample (Figure 7).
[00064] A can containing the same beer from which the sample was obtained was then placed inside the bioceramic-treated beverage holder for 10 minutes. The treated beverage carrier covered about 2/3 of the outside surface of the can. Immediately after the 10-minute exposure period, a beer sample was removed from the can and analyzed by GC-MS (Figure 8). The analysis revealed the disappearance of furfural from the beer. As shown in Figure 8, the mass spectrum of the treated beer did not contain any peaks corresponding to furfural.
