Title: Indium Tin Oxide Coated Particles And Compositions

Description:
TECHNICAL FIELD 
     The invention is in the field of compositions for topical application to keratin surfaces containing Indium Tin Oxide coated particles. 
     BACKGROUND OF THE INVENTION 
     The undesirable effects of ultraviolet radiation on skin are well known. Ultraviolet light is electromagnetic radiation with wavelengths ranging from 100 to 400 nm. UV wavelengths are shorter than those of visible light (which ranges from 400 to 700 nm) but longer than the wavelengths found in X-rays. UV light can be further categorized into UVA, UVB, and UVC. UVA light has wavelengths ranging from 315 to 400 nm. UVB light has wavelengths ranging from 280 to 315 nm. UVC has wavelengths ranging from 100 to 280 nm. UV light can also be categorized by near UV (“NUV”) which is 300 to 400 nm, middle UV (“MUV”) which is 200 to 300, and far UV (“FUV”) which is 122 to 200 nm. It has been shown that exposure to UV light can result in immediate skin tanning or burning and, over time and repeated exposure, increase skin photo aging, which manifests in conditions such as wrinkles, lines, skin laxity and uneven pigmentation. 
     However, less well documented are the effects of infrared (“IR”) light on skin. IR light spans wavelengths ranging from 760 nm to 1 mm and is subdivided into three regions of increasing wavelength: IR-A from 760 nm to 1400 nm, IR-B from 1400 to 3000 nm, and IR-C from 3000 nm to 1 mm. The solar energy that reaches the earth&#39;s surface spans the UV, visible, and IR wavelength ranges. Nearly one half of that solar energy is in the IR range and transmitted in the form of heat. It is known that chronic heat exposure can cause certain skin conditions similar to what is seen in photo-aged skin. For example, a condition known as erythema ab igne results in symptoms such as hyperpigmentation, reticulated erythema, scaling, and telangiectasis in skin surfaces that are exposed to IR radiation over longer periods of time. People who spend a lot of time in heat conditions, such as bakers or jewelers, often exhibit this condition, which may also be referred to as “baker&#39;s arms”, “hot water bottle rash” or “toasted skin syndrome”. Cho, et al., Effects of Infrared Radiation and Heat on Human Skin Aging in vivo,  The Society for Investigative Dermatology , Vol. 14, pages 15-19, 2009, reports that IR-A can penetrate epidermal and dermal layers and reach subcutaneous tissues without noticeably increasing skin temperature. IR-B and IR-C are absorbed mostly in epidermal layers and cause increased skin temperature. Cho further states that repeated exposure to near IR has been shown to cause decreased type I procollagen expression and decreased expression of TGF-β1, β2 and β3 in human skin in vivo. Cho also reports that exposure to IR radiation can impact expression of MMP-1, cause degradation of extracellular proteins such as collagen and elastin fibers, decreased fibrillin production, elastosis, angiogenesis, and so on. 
     For at least these reasons it is desirable to create topical products that protect keratin surfaces such as skin or hair from IR radiation either alone or in conjunction with UV radiation protective effects. 
     Indium tin oxide (“ITO”) is a ternary composition of indium, tin and oxygen in varying proportions. It is typically seen as a formulation of about 74% Indium, 18% oxygen, and 8% Sn by weight. Indium tin compositions can be present without oxygen, in which case they are referred to as “oxygen deficient ITO”. ITO is used to coat industrial substrates such as windows, windshields, or other substrates where it is desired to reflect IR light. For example, it is used to assist in defrosting of aircraft windshields upon application of voltage. One advantage of ITO coated substrates is that they are transparent at wavelengths corresponding to visible light, and opaque in the IR and UV ranges. ITO is not known for use in consumer products, and particularly not in topical consumer products for protecting skin against IR radiation, or in compositions that are designed to protect skin from both UV and IR radiation. 
     It is an object of the invention to provide particles coated with ITO that have IR radiation protective effects when formulated into products for topical application to keratin surfaces. In one embodiment of the invention the particles coated with ITO are chemical or physical sunscreens in particulate form. In this case the particles exhibit both UV and IR protective effects. The ITO coated particles protect keratin surfaces from the adverse effects of IR radiation from all sources, but particularly solar IR radiation. 
     It is a further object of the invention to provide a topical composition for protecting keratin surfaces from the adverse effects of IR radiation containing ITO coated particles in an amount sufficient to protect against IR radiation. 
     It is a further object of the invention to provide a topical composition for protecting keratin surfaces from the adverse effects of UV and IR radiation containing chemical or physical sunscreen particles coated with ITO. 
     It is a further object of the invention to provide a method for protecting keratin surfaces from the adverse effects of IR radiation exposure by topically applying a composition containing ITO coated particles. 
     It is a further object of the invention to provide a method for protecting keratin surfaces from the adverse effects of UV and IR radiation by topically applying a composition containing ITO coated chemical or physical sunscreen particles.

     DETAILED DESCRIPTION 
     Definitions 
     All documents referred to herein are incorporated by reference in their entirety unless otherwise stated. 
     All percentages referred to herein are percentages by weight unless otherwise indicated. 
     The term “block” means, with respect to IR or UV radiation, that the radiation is blocked either in whole or in part from causing undesirable effects in the keratin surface either by physically blocking the radiation from reaching the surface, absorbing the radiation when it reaches the surface, or reflecting the radiation when it reaches the keratin surface. 
     The term “keratin surfaces” means skin, hair, or nails. 
     The term “topical” when used to refer to the composition means any composition that is applied to a keratin surface such as skin, hair, or nails. 
     Indium Tin Oxide 
     The ITO used in the invention may be oxygen deficient ITO, or a ternary mixture of indium, tin, and oxygen. The amount of each element may vary from 40-95% Indium, 5-35% oxygen, and 1 to 15% tin. One preferred form of ITO is a ternary mixture of 74% Indium, 18% oxygen, and 8% tin that may be identified by CAS No. 50926-11-9. ITO is most often in the form of a pale yellow to greenish powder depending on the concentration of SnO 2  present. The melting point ranges from 1500-1950° C. It is referred to as a transparent conducting oxide (“TCO”) because of its electrical conductivity and optical transparency in the visible spectrum. Yet ITO is opaque in both the UV and IR wavelength ranges. ITO particles may be found in the nano range (7 to 75 nm) or standard fine grain powder particle sizes ranging from 0.1 to 15 microns, or agglomerated particles usually having a particle size greater than 30 microns, for example from 15 to 50 microns. The particles may be in the form of dispersions in water or organic solvents including mono- or dihydric alcohols such as ethanol, isopropanol, butylene glycol, propylene glycol, and the like. Examples include a dispersion of 30% ITO in isopropanol containing 90% Indium Oxide and 10% tin oxide or dispersions of 20% ITO in water. Other suitable forms include particles of various sizes such as nanoparticles (around 18 nm, or sizes less than 50 nm in diameter), particles of about 40-50 microns or more particularly having 43 microns, also referred to as −325 mesh. Other sources include Indium Corporation of America in Utica, New York where ITO in particle sizes ranging from 0.01 to 50 microns is available. 
     Particles 
     In the preferred embodiment of the invention the ITO is coated onto particles used in cosmetics. Such particles may be pigments, powders, or combinations thereof. These particles may range from 0.001 to 200 microns in diameter. All, or a portion of the particles may be coated with ITO. The particles coated with ITO may include those set forth below: 
     A. Powders 
     The particles may be colored or non-colored (for example white) non-pigmented powders. Suitable non-pigmented powders include zinc oxide or titanium dioxide (which may be micronized, e.g. having a particle size of from about 0.01 to 1 micron and are generally known for having SPF properties, particularly UVA), bismuth oxychloride, titanated mica, fumed silica, spherical silica, polymethylmethacrylate, micronized teflon, boron nitride, acrylate copolymers, aluminum silicate, aluminum starch octenylsuccinate, bentonite, calcium silicate, cellulose, chalk, corn starch, diatomaceous earth, fuller&#39;s earth, glyceryl starch, hectorite, hydrated silica, kaolin, magnesium aluminum silicate, magnesium trisilicate, maltodextrin, montmorillonite, microcrystalline cellulose, rice starch, silica, talc, mica, titanium dioxide, zinc laurate, zinc myristate, zinc rosinate, alumina, attapulgite, calcium carbonate, calcium silicate, dextran, kaolin, nylon, silica silylate, silk powder, sericite, soy flour, tin oxide, titanium hydroxide, trimagnesium phosphate, walnut shell powder, or mixtures thereof. The above mentioned powders may be also be surface treated with lecithin, amino acids, mineral oil, silicone, or various other agents either alone or in combination, which coat the powder surface and render the particles more lipophilic in nature. 
     B. Pigments 
     The particles may comprise various organic and/or inorganic pigments. The organic pigments are generally various aromatic types including azo, indigoid, triphenylmethane, anthroquinone, and xanthine dyes which are designated as D&amp;C and FD&amp;C blues, browns, greens, oranges, reds, yellows, etc. Organic pigments generally consist of insoluble metallic salts of certified color additives, referred to as the Lakes. Inorganic pigments include iron oxides, ultramarines, chromium, chromium hydroxide colors, and mixtures thereof. Iron oxides of red, blue, yellow, brown, black, and mixtures thereof are suitable. 
     Composite particles may be suitable as well. Examples include spherical particles having a gaseous center sold under the trade name Expancel® 551, 820, 920, and DE having INCI names acrylonitrile/vinyl chloride/isobutene copolymer, acrylonitrile/vinylidene chloride/isobutene copolymer, acrylic acid/acrylonitrogens copolymer, isobutene/copolymer of acrylonitrile/methacrylate/acrylate copolymer, isobutene/copolymer of acrylonitrile/methacrylate/acrylate/water, and so on. If desired, these particles may be impregnated with other particles such as chemical or physical sunscreens according to the method set forth in Sojka, et al, U.S. Patent Application No. US2007/0071978. 
     Also suitable are particles referred to as Sunspheres® which are polymeric particles from styrene/acrylates copolymer sold by Dow Chemical Corporation. The styrene/acrylates copolymer particles have a particle size ranging from about 300 to 500 nanometers, more particularly about 400 nanometers. They may be coated with ingredients such as nonionic surfactants or glycols. 
     The Coating Method 
     The ITO may be coated on the particles in a variety of ways. It is preferred that the coating process be one that is operable at temperatures typically used in the preparation of cosmetic ingredients and formulations, which preferably range from room temperature to 350° C. In particular, in one embodiment the temperature at which the ITO coating is applied most desirably does not exceed 300° C. 
     One process for coating ITO onto the particles involves simply mixing ITO power with the particles to form mixtures of ITO and particles. This may be accomplished by physically combining the particles desired for treatment with the ITO. Ratios include from 5 to 80 parts particles to 80 to 5 parts ITO. 
     Another process for coating ITO onto the particles may accomplished by a process referred to as physical vapor deposition (“PVD”) or sputter deposition which is a form of PVD. PVD uses physical forces to apply layers or coatings to the particulates. In PVD the desired particles may be prepared by drying them in an oven at sufficient temperature to remove any residual water. The drying may take place at temperatures ranging from 70 to 300° C., or at about 125° C. for a period of time to evaporate moisture. Depending on how much moisture is in the particles, this time can range from 1 to 24 hours. The dry particles are then put into a vacuum chamber and air is removed. A background pressure ranging from 10 −6  to 10 −4  torr may be used. A sputtering gas is then introduced. One example of a suitable gas may halogens such as argon or carbon tetrafluoride, and the like. The sputtering gas is added in an amount sufficient to obtain the desired background pressure in the system, which may range from 1 to 20 millitorr. The ITO is then introduced into the chamber. Alternatively, the indium and tin can be added and oxygen introduced into the chamber, however in this case the amount of oxygen present in the final product is not always consistent. In one embodiment the vacuum sputtering system may be operated in DC magnetron mode. The particles are tumbled slowly in the sputtering target with time and power chosen to produce coatings that are thick enough to provide particles that have the desired particle size. Sputtering times can range widely, from 2 to 25 hours with power levels also varying from 1 to 10 kilowatts. When the target is ITO it takes place in an oxygen free environment. After sputtering is concluded, if desired, the particles can be heated in air to dry. PVD is an effective and efficient coating process and provides a continuous, uniform, and strongly adherent coating of the ITO on the treated particles. PVD systems suitable for sputter coatings may be purchased from PVD Products, Wilmington, Mass. Examples of such systems include Magnetron Sputter Deposition Systems that may be in rectangular or cylindrical configurations and options for sputtering up or sputtering down. The chambers may be vacuum or cryogenic. 
     Also suitable as a coating method are chemical vapor deposition (“CVD”) which is formation of a thin film on a substrate by chemical reaction of vapor phase precursors. The reaction occurs in the gas phase and on the substrate. CVD deposition of ITO films onto particles may be achieved by reacting indium metal acetate precursors such as indium acetate and tin acetate with the particles desired to be coated according to processes as disclosed in Maruyama and Tabata, Indium-Tin Oxide Thin Films Prepared by Chemical Vapor Deposition from Metal Acetates,  Japanese Journal of Applied Physics , Volume 29, Part 2, No. 2 (1990). 
     It is also possible to coat particles using thermal methods, although in this case the particle to be coated must not be degraded upon exposure to the high temperatures required to deposit the coating. These temperatures may range from 300 to 1,000° C. In this application the ITO is heated with the particle in a high temperature furnace which causes the ITO to deposit on the surface of the particle. The temperature typically ranges from 1000 to 1200° C. 
     Various processes for depositing ITO onto particles may be found in Martin Friz and Friederich Waibel,  Coating Materials , Springer Series in Optical Sciences, 2003, pages 105-130. 
     Pulsed laser deposition in high vacuum chamber which may be accompanied by reactive and ion-assisted sputtering is also a suitable deposition method. 
     Another suitable process is electrospinning sol-gel prepared ITO coatings on substrates followed by thermal processing as set forth in Zhang, et al.,  Optical Materials  26 (2004) pages 47-55. In this process sol-gel ITO is prepared and spin coating is used to apply the coating to the particles followed by heat treatment at temperatures ranging from 175 to 600° C. 
     The ITO may be coated onto the particles with a suitable process that does not degrade the particles and is otherwise compatible with the ITO, the particle and the other ingredients used in the process. The coating may range in thickness from 0.1 to 1000 nanometers, or from 0.5 to 25% of the total particle by weight. 
     The Compositions 
     The ITO coated particles may be incorporated into a variety of compositions that may be in the anhydrous, emulsion, gel, or solution form. The ITO particles may range from 0.1 to 60%, preferably from about 0.5 to 50%, more preferably from about 1 to 40% by weight of the total composition. 
     The topical composition may contain other ingredients including but not limited to those set forth below:
