Description

Title of the invention: TRANSPARENT BOTTLE WITH UV COATING FOR UV GEL COMPOSITIONS SYSTEMS AND PROCESSES FOR NAILS Summary

[0001] The present invention relates to a transparent bottle with one or more layers of transparent UV coating containing a UV nail polish or gel composition having a photoinitiator that is simultaneously operational to prevent the UV nail gel formula from hardening, from gelling, while giving visibility to the UV nail polish.

[0002] Typical UV nail polish or gel formulations contain methacrylate monomers and a photoinitiator, such as benzoyl peroxide. Upon exposure to UV light, the nail polish hardens, polymerizes, and solidifies. Curing wavelengths typically range from 340 to 380 nanometers (nm). However, with prolonged exposure to light, the nail polish hardens, gels, and forms clumps in its storage container or bottle.

[0003] Consequently, UV nail polish gels cannot typically be stored in transparent bottles, and therefore a color indicator or description must be used to notify the consumer of the color. In order to mitigate or prevent hardening of the UV nail polish composition while in the bottle, conventional bottles must be tinted or opaque to block UV light. There is a need in the art for a system providing a transparent bottle containing UV nail polish or gel formulations, so that the color, tint, and pigment of the nail polish are readily visible to a user.

[0004] The invention provides a two-part system. The first part of the system comprises a transparent UV-blocking coating arranged in layers or applied to a transparent flint glass or a transparent polymer bottle capable of blocking UV wavelengths from 100 nm to 380 nm to prevent the formula from easily gelling in natural light. The second part of the system comprises a UV nail polish or gel formula that includes a lower curing photoinitiator, preferably with a wavelength below 330 nm, to ensure the compatibility of the gel or nail polish formula with the transparent bottle coated with the transparent UV blocker. The combination of the modified UV-curable formulation results in greater stability within the UV-protective transparent glass bottle compared to conventional coatings.

[0005] In one embodiment, a transparent bottle and UV nail gel system is provided for protecting the UV nail gel formulation from hardening or gelling while allowing visibility of the UV nail gel formula. The system comprises one or more layers of a transparent UV-blocking treatment located on an outer surface of the transparent bottle, including one or more UV absorbers having an intramolecular hydrogen bond and absorption wavelengths ranging from 100 nm to 380 nm, associated with a UV nail gel formula comprising a lower curing photoinitiator having an absorption wavelength < 330 nm.One or more layers of the UV-blocking clear treatment and the UV gel nail formula with the lower curing photoinitiator protect the UV gel nail formulation from hardening or gelling while providing visibility of the UV gel nail formula.

[0006] In one embodiment, the UV absorbers are chosen from o-hydroxybenzophenones, 2-(2-hydroxyaryl)-benzotriazoles and 2-(2-hydroxyaryl)-l,3,5-triazines.

[0007] In one embodiment, the photoinitiator is 1-hydroxycyclohexyl phenyl ketone.

[0008] The UV-blocking treatment preferably comprises at least two layers on the outer surface of the transparent bottle. More preferably, the transparent bottle and UV-blocking nail polish system, in which the UV-blocking treatment comprises at least three layers on the outer surface of the transparent bottle.

[0009] In one embodiment, the one or more UV-blocking treatment layers on the outer surface of the transparent bottle have a thickness varying between 0.1 pm and 200 pm.

[0010] In yet another embodiment, the transparent bottle is a glass bottle. In another embodiment, the transparent bottle is a polymer bottle.

[0011] Another embodiment provides that one or more layers of a transparent UV-blocking treatment located on an external surface of the transparent bottle are applied by spraying.

[0012] One or more layers of a transparent UV-blocking treatment located on an external surface of the transparent bottle can be applied by filming.

[0013] In one embodiment, one or more layers of a transparent UV-blocking treatment cover substantially the substantially entire outer surface of the transparent bottle.

[0014] Another embodiment provides that one or more layers of a transparent UV-blocking coating substantially cover a portion of the base, a body, and at least part of a portion of the neck of the transparent bottle. The base and body represent the main cavity containing the UV nail gel.

[0015] A method for constructing a transparent bottle and UV-blocking nail polish system is also provided. The method comprises the steps, in any order, of applying one or more layers of a transparent UV-blocking treatment to an external surface of the transparent bottle comprising one or more UV absorbers having an intramolecular hydrogen bond and absorption wavelengths ranging from 100 nm to 380 nm; and of inserting into the transparent bottle a UV nail polish or gel formula comprising a lower curing photoinitiator having an absorption wavelength of less than 330 nm.In which one or more layers of the UV-blocking transparent treatment and the UV gel nail formula with the lower curing photoinitiator protect the UV gel nail formulation from hardening or gelling while conferring visibility of the UV gel nail formula.

[0016] This summary is provided to present a selection of concepts in a simplified form, which are further described below in the detailed description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. Description of the figures

[0017] The foregoing aspects and advantages of the inventive technology will be more readily appreciated by a better understanding with reference to the following detailed description, taken together with the accompanying drawings, in which:

[0018] [Fig-1] [Fig. 1] is a graph showing the wavelength and transmittance of light for flask samples;

[0019] [Fig.2a] [Fig.2a] is a photograph showing comparative non-inventive samples A-0 and Al after 24 hours of testing in sunlight or exposure to light;

[0020] [Fig.2b] [Fig.2b] is a photograph showing a comparison of the non-inventive sample B-0, and the inventive inventive samples Bl to B-3 after 24 hours of exposure to light;

[0021] [Fig.2c] [Fig.2c] is a photograph of the samples from [Fig.2b] after 48 hours of exposure to light. Detailed description

[0022] Conventional UV nail polish bottles are tinted to prevent the UV nail polish formula from gelling (it hardens at 340 nm to 380 nm) since it can easily harden with light over time. Consequently, typical UV-sensitive formulas are stored in a tinted bottle, so the color of the nail polish composition is not visible to consumers.

[0023] The bottle of the invention with a UV coating for nail polish compositions, systems, and methods of use provides a transparent (non-opaque) treatment on the exterior of a transparent bottle. The transparent bottles are treated with a transparent UV-blocking formulation capable of blocking UV wavelengths from 100 nm to 380 nm. The bottle treatment is achieved by transparent coating applied by spraying, rubbing, vacuum chamber application, sand shrink wrapping, or other processes or combinations thereof to obtain at least one coating or layer of sufficient thickness to provide protection to the formula against UV degradation. In combination, the UV nail gel formula is modified to have a curing wavelength of less than 330 nm to ensure that the formula is well protected by the transparent coating.

[0024] Combining the UV-blocking coating with the UV-curing nail formulation of a specific wavelength allows the highly UV-sensitive cosmetic formula to be protected while still allowing the formula's color to be seen. As a result, consumers can perceive the formulation's physical properties, such as color, texture, visual effects, etc., through the transparent film, and the UV-sensitive formula remains protected against gelling and / or degradation due to UV light exposure. Preferably, the UV-blocking transparent film or coating comprises at least one coating and preferably covers 360 degrees around the bottle. Ideally, the UV transparent film covers substantially the entire outer surface of the bottle.

[0025] Figure 1 is a graph showing the wavelength and light transmittance for sample bottles. The inventive sample is a UV-coated bottle of the invention. Sample X is a transparent bottle without a UV coating. Sample Y is an amber bottle. Sample Z is an opaque white bottle. The inventive sample shows blockage or low transmittance below 380 nm compared to Sample X, which is a transparent bottle without a UV coating. Sample Y, an amber bottle, shows low transmittance below 480 nm. Sample Z, the opaque white bottle, exhibits low transmittance across the wavelength spectrum. However, using the opaque white bottle of Sample Z is not advantageous because it does not allow visibility of the gel or UV nail treatment. Sample Y, bottle Amber light does not provide visibility of the UV nail gel, but rather shows a distorted color / distorted indicators of the gel. In comparison, the inventive sample shows an increased percentage of transmittance at higher wavelengths, above approximately 410 nm, demonstrating visibility that allows the UV nail gel formula to be seen in the bottle.

[0026] A conventional UV nail polish formula gels or hardens at approximately 340 nm to 380 nm. Sample X, the uncoated transparent bottle, absorbs wavelengths generally ≥ 300 nm. The inventive sample, the UV-coated transparent bottle, begins transmitting light at wavelengths of approximately 380 nm. The inventive sample is capable of blocking UV wavelengths from 100 nm to 380 nm to prevent the UV nail formula from gelling in natural light. Simultaneous operation with the modified UV gel formula of the invention, using a lower curing photoinitiator of less than 330 nm, ensures the formula's compatibility with the UV-blocking transparent coating on the bottle. The combination of the UV-curable formula exhibits the best stability with transparent glass coated with a UV-protective coating.

[0027] Figure 2a is a photograph showing the comparative non-inventive samples A-0 and A1 after 24 hours of sunlight or light exposure. Figure 2b is a photograph showing a comparison of the non-inventive sample B-0 and the inventive samples B1 to B-3 after 24 hours of light exposure. Figure 2c is a photograph of the samples from Figure 2b after 48 hours of light exposure. The sunlight test methodology consists of exposing the samples in a UV light chamber that is continuously activated.

[0028] Referring to Figures 2a and 2b, all samples used a clear glass bottle. Sample A-0, uncoated, formula with a UV curing range of 340 nm to 380 nm. Sample A1, coated with one layer, formula with a UV curing range of 340 nm to 380 nm. Sample B-0 represents an example with no coating, no UV coating, or zero (0) coating on the outside of the bottle, and a UV formula for nails having a UV curing range < 330 nm. The inventive samples B1 to B3 represent examples with one (1) layer, up to three (3) coatings or layers on the outside of the bottle, and a UV formula for nails having a UV curing range < 330 nm. The UV absorbers preferably used in the UV coating of the outer surface of the bottle include a UV blocker having one or more intramolecular hydrogen bonds.Preferably, the UV blocker is chosen from among o-hydroxybenzophenones, 2-(2-hydroxyaryl)-benzotriazoles, 2-(2-hydroxyaryl)-l,3,5-triazines, and their combinations.

[0029] After a 24-hour sun test, both samples A-0 and Al hardened, gelled, or solidified completely. Even with the UV coating layer on the bottle for sample Al, after a 24-hour sun test, the UV nail formula solidified. After 48 hours, the formula of sample B3 exhibited optimal fluidity, 100% fluidity without hardening. Consequently, applying three coats of the UV-blocking coating in combination with the claimed UV gel formulation with the photoinitiator demonstrated optimal performance over time.

[0030] [Tables 1] Sample Bottle: Number of external UV coating(s) UV formula for nails: UV curing range Results: 24 hours Results: 48 hours Sample A 0 coating 340 nm to 380 nm cured; solidified / gelled ___ Sample B0 0 coating < 330 nm slightly solidified hardened; well solidified Sample B1 inventive 1 coating < 330 nm transparent; not cured very slightly cloudy Sample B2 inventive 2 coatings < 330 nm transparent; not cured very, very slightly cloudy Sample B3 inventive 3 coatings < 330 nm transparent; not cured transparent; not cured

[0031] A sunlight test was performed, in which the samples were exposed to sunlight and examined in terms of their curing state, specifically at 1 hour and 24 hours. The examples above illustrate 1) Sample A without UV coating and UV nail gel with a photoinhibitor at 340 nm to 380 nm, which resulted in a cloudy gel at 1 hour and a significantly cloudy gel at 24 hours. Sample B0 with no coating and UV nail gel at < 330 nm performed better than Sample A with UV nail gel at 340 nm to 380 nm; however, comparatively, Samples B1 to B3 with a combination of UV coating plus UV nail gel at < 330 nm all performed better than Sample A and Sample B at 1 hour and 24 hours. Furthermore, for samples B1 and B2, it turned out that 3 coatings were the ideal solution, giving transparent visibility at 1 hour and 24 hours. Example(s)

[0032] A clear glass bottle has been treated with any UV-protective coating. The clear bottles have been treated with a transparent UV blocker by spray application of the transparent coating. The transparent UV blocker can be applied by spraying, rubbing, vacuum chamber, shrink wrapping, sandblasting, etc., to the outside of the bottle to act in concert with the UV nail gel containing a photoinhibitor at < 330 nm for enhanced protection of the formula against UV degradation. As shown above, at least one layer is applied to the outer surface of the bottle, preferably at least two layers, and ideally at least three layers. It should be noted that, while "layers" are mentioned, the thickness of the layer(s) can be modified so that a single layer can have the thickness of two or more layers.Preferably, a coating on the bottle has a thickness ranging from 0.1 pm to 200 pm, including all layers / the sum of the layer thicknesses.

[0033] The ingredients of UV protective coatings are UV absorbers with an intramolecular hydrogen bond (e.g., o-hydroxybenzophenones, 2-(2-hydroxyaryl)-benzotriazoles, and 2-(2-hydroxyaryl)-l,3,5-triazines), a UV-resistant transparent acrylic coating, such as that sold under the trade name Krylon, acetone, n-butyl acetate, propane, butane, xylene, a mixture of isomers, ethyl 3-ethoxypropionate, a solvent, polyester, additives (TiO2, silica, etc.), PTFE, PVDF, FEP, and PEEK™. The only plastics that have proven to have excellent resistance are imides, polyimide (PI), and polyetherimide (PEI).

[0036] It was discovered that the above-mentioned example of the invention with the photoinitiator 1-hydroxycyclohexyl phenyl ketone, in combination with the UV-coated bottle, yielded a clear, unclouded UV nail polish composition after three days of light exposure. In comparison, the above-mentioned example with ethyl trimethylbenzoyl phenylphosphinate solution yielded a cloudy UV nail polish composition after three days. Consequently, the example of the invention with the photoinitiator 1-hydroxycyclohexyl phenyl ketone with a bottle having a transparent UV-blocking film or coating covering wavelengths from 100 nm to 380 nm, particularly 360 nm, on the outside of the bottle provided improved protection against light degradation over a prolonged period.
