Description
Title of the invention: GEL COMPOSITIONS CONTAINING BIS-ETHYLHEXYLOXYPHENOL METHOXYPHENYL TRIAZINE AND AN ESTER-BASED GELLING AGENT SUGAR FATTY ACID FIELD OF THE INVENTION
[0001] The present disclosure relates to gel compositions comprising 2,4-bis-{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine (INCI name: bis-ethylhexyloxyphenol methoxyphenyl triazine), at least one sugar fatty acid ester gelling agent, and at least one solvent for solubilizing the bis-ethylhexyloxyphenol methoxyphenyl triazine and / or thickening the composition when combined with the at least one sugar fatty acid ester gelling agent, as well as methods of making and using such compositions. BACKGROUND DISCUSSION
[0002] Radiation with wavelengths between 290 nm and 400 nm allows tanning of the human epidermis, while radiation with wavelengths between 290 and 320 nm, called UVB rays, hinders the development of a natural tan. Exposure is also likely to cause a detrimental change in the biomechanical properties of the epidermis, resulting in the appearance of wrinkles leading to premature aging of the skin (i.e., photoaging).
[0003] UVA rays with a wavelength between 320 and 400 nm penetrate deeper into the skin than UVB rays. UVA rays cause immediate and persistent browning of the skin. Daily exposure to UVA rays, even for a short time, under normal conditions, can damage collagen fibers and elastin, resulting in a change in the microrelief of the skin, the appearance of wrinkles and uneven pigmentation (spots, uneven skin tone).
[0004] Numerous studies show the need for effective protection against UVA and UVB to prevent sunburn, photoaging, and the like.
[0005] In order to obtain a high protection product, it is generally necessary to combine a large number of sunscreens and / or a large amount of UV filters to achieve high levels of filtration efficiency.
[0006] However, the high levels of UV filters do not lend themselves to easy preparation of compositions having a stabilized and pleasant texture, particularly in the form of a gel. This is particularly true for compositions containing solid UV-filter bis-ethylhexyloxyphenol methoxyphenyl triazine that may be solubilized during formulation. For example, gel compositions containing bis-ethylhexyloxyphenol methoxyphenyl triazine, when broken (e.g., unstable or showing signs of crystallization) during or prior to application, may exhibit a lack of homogeneity upon application, resulting in less sun protection from the composition than expected.
[0007] There remains a need in the art for improved gel compositions containing bis-ethylhexyloxyphenol methoxyphenyl triazine, particularly transparent or translucent gel compositions, which possess good UV protection capabilities in addition to good application and use properties, particularly homogeneous spreading upon application.
[0008] Accordingly, one aspect of the present disclosure is a gel composition containing bis-ethylhexyloxyphenol methoxyphenyl triazine which has good UV protection properties and / or good application and use properties, including homogeneous spreading upon application. Summary of the Invention
[0009] The present disclosure relates to gel compositions comprising bis-ethylhexyloxyphenol methoxyphenyl triazine (bemotrizinol or BEMT), at least one sugar fatty acid ester gelling agent, and at least one solvent for solubilizing the bis-ethylhexyloxyphenol methoxyphenyl triazine and / or thickening the composition when combined with the at least one sugar fatty acid ester gelling agent. Preferably, the bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is added to the compositions in an amount effective to protect the keratinous material from UV radiation. Preferably, the compositions further comprise at least one lipophilic acrylate thickening agent. Preferably, the compositions are transparent or translucent.
[0010] The present disclosure also relates to methods of making gel compositions comprising combining bis-ethylhexyloxyphenol methoxyphenyl triazine, at least one sugar fatty acid ester gelling agent and at least one solvent to solubilize the bis-ethylhexyloxyphenol methoxyphenyl triazine and / or thicken the composition when combined with the at least one sugar fatty acid ester gelling agent in the compositions during formation of the compositions. Preferably, bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is added to the compositions in an amount effective to protect the keratinous material from UV radiation. Preferably, at least one lipophilic acrylate thickening agent is also added during formation compositions. Preferably, the compositions are transparent or translucent.
[0011] The present disclosure also relates to methods of improving homogeneity of gel compositions comprising bis-ethylhexyloxyphenol methoxyphenyl triazine during application, the method comprising adding bis-ethylhexyloxyphenol methoxyphenyl triazine, at least one sugar fatty acid ester gelling agent and at least one solvent to solubilize the bis-ethylhexyloxyphenol methoxyphenyl triazine and / or thicken the composition when combined with the at least one sugar fatty acid ester gelling agent in the compositions during formation of the compositions in amounts sufficient to improve the homogeneity of the gel composition during application. Preferably, the compositions further comprise at least one lipophilic acrylate thickening agent. Preferably, the compositions are transparent or translucent.
[0012] It should be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and do not limit the disclosure. DETAILED DESCRIPTION OF THE INVENTION
[0013] In the following description and the claims appended thereto, it is to be understood that the terms used have their ordinary and customary meanings in the art, unless otherwise specified.
[0014] “Approximately” as used herein means within 10% of the number indicated (e.g. “about 10%” means 9% to 11% and “about 2%” means 1.8% to 2.2%.
[0015] “A” or “an” as used herein means “at least one”
[0016] “At least one” means one or more and thus includes components in individual as well as mixtures / combinations.

[0020] “Volatile,” as used herein, means having a flash point less than about 115 C.
[0021] “Non-volatile,” as used herein, means having a flash point greater than about 115°C.
[0022] “Polymer” as used herein means a compound that is made up of at least two monomers.
[0023] “Exempt” or “substantially free” or “devoid of” as used herein means that although it is preferred that no amount of the specific component be present in the composition, it is possible for there to be very small amounts thereof in the compositions of the disclosure, provided that such amounts do not materially affect at least one, preferably most, of the advantageous properties of the compositions of the disclosure. Thus, for example, "oil-free" means that an effective amount (i.e., greater than trace amounts) of oil(s) is omitted from the composition (i.e., about 0% by weight), "substantially oil-free" means that oil(s) is / are present in amounts not greater than 0.1% by weight, and "oil-free" means that oil(s) is / are present in amounts not greater than 0.25% by weight, based on the total weight of the composition.The same nomenclature applies to all other ingredients identified throughout the application and in this paragraph such as, for example, specific UV filters and / or surfactants (the compositions in the disclosure that are “oxybenzone and / or octinoxate-free,” “substantially oxybenzone and / or octinoxate-free,” and “oxybenzone and / or octinoxate-free,” as well as “surfactant-free,” “substantially surfactant-free,” and “surfactant-free” have meanings consistent with the discussion in this paragraph), even if not specifically discussed for each identified ingredient. The discussed examples of the use of such language as those in this paragraph are intended to be provided by way of example, not limitation.
[0024] “UV filters” as used herein means approved sunscreen active agents by a government regulatory agency such as the Food and Drug Administration (FDA) in the United States or the European Commission in Europe and includes avobenzone, octocrylene, benzophenones, benzotriazoles and merocyanines, as well as mineral UV filters such as zinc oxide (ZnO) and titanium dioxide (TiO2).
[0025] “Anhydrous” as used herein means that the compositions of the disclosure contain less than 3% water, which means that the compositions may also contain less than 2% water, and less than 1% water, as well as be “water-free”, “substantially water-free” and “water-free” as defined above.
[0026] “Keratinous materials” refer to nails (fingernails and / or toenails), skin such as that of the body, face and eye area, scalp, keratinous fibers such as eyelashes, eyebrows and hair, and mucous membranes such as the lips.
[0027] “Physiologically acceptable” means compatible with the gel and having a pleasant color, odor and feel, and which does not cause unacceptable discomfort (tingling or tightness) likely to discourage a consumer from using the composition.
[0028] “UV protection efficiency” or “filtration efficiency” in the context of present disclosure, is evaluated from one or more of SPF, FPUVA, critical wavelength and UVA-I / UV ratio.
[0029] "SPF" (Sun Protection Factor) measures the level of protection against erythema provided by a composition. The SPF value corresponds to the ratio between the minimum erythema dose (MED) measured on skin covered with the composition and the MED measured on bare skin. The term "SPF" is known in the art of sunscreens and is defined, for example, in A new substrate to measure sunscreen protection factors throughout the ultraviolet spectrum, J. Soc. Cosmet. Chem., 40, 127-133 (May / June 1989).
[0030] The SPF (Sun Protection Factor) assessment can be carried out, for example, in vitro with a Labsphere spectrophotometer (North Sutton, NH, USA). In such an assessment, the plate is the material onto which the composition under test is applied. Polymethyl methacrylate (PMMA) plates can be used for such an assessment. An example of an acceptable protocol is currently undergoing ISO accreditation as ISO Committee Draft 23675.
[0031] The evaluation of the sun protection factor (SPF) can also be carried out in vivo in accordance with the ISO 24444:2019 protocol “Cosmetics-Sun protection test methods-In-vivo determination of the sun protection factor (SPF).” It can also be determined in accordance with FDA protocols, as described in the document “Labeling and Effectiveness Testing; Sunscreen Drug Products for Over-the-Counter Human Use” published in the US Federal Register on 07 / 05 / 2011 (https: / / www.federalregister.gOv / d / 2011-14766); 21 CFR Part 352 Subpart D § 352.72, updated and revised by the 2011 publication in the Federal Register.
[0032] “UVA protection factor” (UVA protection factor) refers to a characteristic index tering the UVA protection provided by a composition. For example, the UVA factor may be measured in vivo in accordance with the "PPD" (Persistent Pigment Darkening) method of the ISO-24442:2022 protocol, measuring skin color observed 2 to 4 hours after UVA exposure. It may also be determined in accordance with FDA protocols, as described again in 21 CFR Part 352 Subpart D § 352.72 as discussed above in relation to SPF.
[0033] The assessment of UVA protection can also be measured in vitro with the Labsphere® spectrophotometer under conditions such as those mentioned above in relation to SPF. The ISO 24443:2021 protocol describes such an in vitro method.
[0034] The FDA's broad spectrum test procedures, specifically the "critical wavelength" test procedures, are also available in 21 CFR Part 352 Subpart D § 352.72. In addition, the broad spectrum test procedures include the determination of the UVA1 / UV ratio as described in "Sunscreen Drug Products for Over-the-Counter-Human-Use" published in the Federal Register https: / / www.federalregister.gov / documents / 2019 / 02 / 26 / 2019-03Q19 / sunscreen-drug-pr oducts-for-over-the-counter-human-use. » In the assay described in the monograph, known as the Boots adaptation of the Diffey / Robson test method, a ratio is generated between the protection provided by the sunscreen product against UVA1 (340-400 nm) and the protection against total UV radiation (UVB and UVA at 290-400 nm) calculated from the absorbance curve. This UVA1 / UV ratio would represent the product's score in the in vitro test.
[0035] According to the present disclosure, the compositions of the present disclosure preferably have one or more of the following properties:
[0036] The compositions have a critical wavelength as determined by FDA critical wavelength procedures of at least 370 nm;
[0037] The compositions have an SPF value of at least 15, preferably at least 30, preferably at least 50 and preferably at least 70;
[0038] The compositions have an FPUVA / SPF ratio of at least 1 / 3, and preferably at least 2 / 5 and / or
[0039] The compositions have a UVA1 / UV ratio of 0.7 or more, preferably 0.75 or more, and preferably 0.8 or more.
[0040] “Makeup result” as used herein refers to the visual impact of a composition when applied to keratinous material such as skin. makeup result may concern the apparent color of the product after application to a keratinous material or an optical effect such as shine, the blurring of fine lines and imperfections, or a concealing effect on pores or defects after application of the product to the keratinous material.
[0041] “Long-lasting” as used herein refers to compositions where the color or other apparent properties remain the same or substantially the same as at the time of application, as seen with the naked eye, after an extended period of time, or after a particular stress event such as immersion in water or rubbing. “Long-lasting” may be evaluated by evaluating long-lasting properties by any method known in the art for evaluating such properties. For example, long-lasting may be evaluated by a test involving the application of a composition to a keratinous material such as skin and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately after application to a keratinous material such as skin, and these characteristics may then be re-evaluated and compared after a period of time.In addition, these characteristics can be evaluated relative to other compositions, such as commercially available compositions. “Long wear” can also be evaluated using in vitro methods on non-keratinous substrates such as polymethyl methacrylate (PMMA), in which properties such as color, transparency, or in vitro SPF can be evaluated before and after a period or stressor such as immersion in water, incubation at elevated temperatures, or application of an abrasive technique.
[0042] “Improving the homogeneity of a gel composition during application” such as as used herein means obtaining or achieving a more uniform distribution of bis-ethylhexyloxyphenol methoxyphenyl triazine when applying a sample gel composition (e.g., a composition containing at least one sugar fatty acid ester gelling agent) than when applying a comparative gel composition (e.g., a composition not comprising at least one sugar fatty acid ester gelling agent).
[0043] Improvement in homogeneity of a gel composition during application may be determined by comparing the distribution of in vitro SPF values on a polymethyl methacrylate (PMMA) plate using a controlled application technique and a Labsphere UV-2000S. Preferably, the number and distribution of measured locations are compared uniformly between multiple samples to determine homogeneity, with the most homogeneous sample exhibiting less variation between locations than a comparatively inhomogeneous sample. The distribution of sample homogeneity may be readily expressed as a function of the coefficient of variation or standard deviation. In another example, improvement in homogeneity of a gel composition during application may be determined by visual or measurable comparison of the distribution of thin films generated using a stretching machine with an appropriately chosen thickness level, manual application to a substrate following a standardized protocol, or comparison of the product applied to the skin. Methods of comparing thin film preparations of gel compositions for the purpose of assessing improvement in homogeneity of a gel composition during application may include visual judgment, colorimetric measurement, image analysis and comparisons, other spectroscopic analyses, or machine learning methods involving visual models.Comparisons can be made using the entire movie or a number of representative locations within each movie.
[0044] “Transparent” or “translucent” as used herein refers to compositions having a turbidity, measured according to the following method, of less than 800 NTU (nephelometric turbidity units). In preferred embodiments, the turbidity is less than 500 NTU. The turbidity can be measured using a Hach Model 2100 P Turbidimeter at room temperature (20 to 25 °C). The tubes used for the measurement are referenced AR 397 A cat 24347-06. The apparatus is calibrated using formazin suspensions of different concentrations. Alternatively, transparency can be measured as a visual comparison between two samples maintained under identical processing conditions, related to a relative comparison of the light transmitted through two samples.Other examples of transparency or translucency measurements may involve applying the composition as a film of controlled thickness to a transparent substrate and visually inspecting the amount of light passing through the sample, or comparing the visibility of a controlled pattern placed on the back of the transparent substrate and the controlled film of the composition under controlled lighting conditions.
[0045] “Natural” as in the expression “natural compound” means any compound derived directly from a natural substance such as a plant without undergoing chemical modification.
[0046] “Naturally occurring compound” means any compound derived from a naturally occurring compound which has undergone one or more chemical modifications, for example by organic synthesis reaction, without the properties of the natural compound having been modified.
[0047] “Synthetic compound” means any compound that is neither a natural compound nor a compound of natural origin.
[0048] “Room temperature” means approximately 20 to 25°C.
[0049] “Atmospheric pressure” means approximately 760 mmHg, i.e. approximately 105 pascals.
[0050] “UV filter” and “sunscreen agent” are used interchangeably in this request.
[0051] The terms “UV efficacy”, “UV protection” and “UV efficacy” are used interchangeably in the present application.
[0052] The compositions and methods of the present disclosure may comprise, consist of, or consist essentially of the essential elements and limitations of the disclosure described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful. For example, the UV (ultraviolet) absorbing system of the compositions of the disclosure may "consist essentially of" bis-ethylhexyloxyphenol methoxyphenyl triazine alone, or bis-ethylhexyloxyphenol methoxyphenyl triazine in combination with zinc, titanium, and / or cerium oxides, and / or one or more organic UV filters. Further, by way of example, the homogeneity-enhancing system of the gel composition may "consist essentially of" sugar fatty acid ester gelling agent(s) and optionally lipophilic acrylate thickening agent(s).
[0053] For the purposes of this disclosure, the "fundamental and novel property" associated with the compositions, components and methods that "consist essentially of" the identified ingredients or actions is "improving the homogeneity of a gel composition during application."
[0054] Reference is made herein to trade names of materials including, but not limited to, materials such as polymers and optional components. The materials are not intended to be limited by the materials described and referenced by a certain trade name herein. Equivalent materials (e.g., those obtained from a different source under a different catalog name or (reference) number) to those referenced by a trade name may be substituted and used in the methods described and claimed herein.
[0055] All percentages and ratios are, unless otherwise indicated, calculated by weight. All percentages are, unless otherwise indicated, calculated based on the total weight of a composition. All levels of component or composition refer to the active level of that component or composition, and are exclusive of impurities, e.g., residual solvents or by-products, which may be present in commercially available sources.
[0056] All US patents or patent applications disclosed herein are expressly incorporated by reference in their entirety. Gel composition
[0057] According to the present disclosure, gel compositions comprising a system UV (ultraviolet) absorbers comprising 4-bis-{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-l,3,5-triazine (INCI name: bis-ethylhexyloxyphenol methoxyphenyl triazine) are provided. The gel compositions according to the present disclosure may be solid (e.g., in the form of a stick) or non-solid.
[0058] The term "gel composition" as used herein refers to any composition that is semi-solid or solid at room temperature and atmospheric pressure. Preferably, the gel compositions are transparent or translucent. In some embodiments, the gel composition may appear cloudy or hazy to milky white. Solid gel compositions
[0059] According to preferred embodiments, the compositions of the present disclosure may be solid (e.g., in stick form). By "solid" is meant in particular a composition whose hardness can be measured according to the "cheese wire" method. These compositions may contain little or no water (e.g., be anhydrous, "free of", "substantially free of", "free of" water), contain little or no oil (e.g., be "free of", "substantially free of", "free of" oil), be in emulsion form (e.g., oil-in-water emulsion or water-in-oil), etc.
[0060] The hardness of a composition may, for example, be expressed in grams-force (gf). The composition of the present disclosure may, for example, have a hardness ranging from 20 gf to 2000 gf, such as from 20 gf to 900 gf, and further such as from 20 gf to 600 gf, including all intermediate ranges and sub-ranges.
[0061] The measurement of hardness may be illustrated by the following two examples. First, the "cheese cutting wire" method noted above, which involves cutting a composition into a 12.4 mm diameter stick and measuring its hardness at 20°C using a DFGHS 2 tensile testing machine from Indelco-Chatillon Co. or a similar machine at a speed of 100 mm / minute. The hardness value obtained by this method is expressed in grams as the shear force required to cut a stick under the above conditions. According to this method, the hardness of the compositions according to the present disclosure which may be in stick form may, for example, range from 120 gf to 270 gf, preferably from 170 gf to 220 gf, for a sample of 12.4 mm diameter.
[0062] If desired, another hardness test is carried out using a method of penetrating a probe into the composition and in particular using a texture analyzer (for example the PLUS-UPGRADE model texture analyzer from Stable Micro Systems equipped with a stainless steel cylinder 28 mm high and 2 mm in diameter). The hardness measurement can be carried out at 20 °C at the center of 5 samples of the composition. The cylinder is introduced into each composition sample at a pre-speed of 2 mm / s, then at a speed of 0.5 mm / s and finally at a post-speed of 10 mm / s, the total displacement being 2 mm. The hardness value recorded is that of the first maximum peak before the observed drops in value.
[0063] The hardness of the composition of such preferred embodiments is preferably such that the compositions are self-supporting and can readily disintegrate to form a satisfactory deposit on the skin. Further, this hardness may impart good impact resistance to the compositions disclosed herein, which may be molded or cast, for example, in stick or capsule form. Non-solid gel compositions
[0064] According to preferred embodiments, the gel compositions can be prepared by incorporating any of the ingredients discussed herein, in an amount sufficient to prepare a non-solid gel composition (e.g., a gel not meeting the hardness properties set forth above).
[0065] In preferred embodiments, the compositions of the present disclosure are in the form of a gel having a gel crossover point ranging from about 2% to about 50% strain, preferably from about 3% to about 40% strain, and most preferably from about 4% to about 30% strain, including all intermediate ranges and sub-ranges. The term "gel crossover point" (Sol / Gel point) means the point at which G" (loss modulus) crosses G' (storage modulus), reported as % strain. This is the point at which a composition changes from a more solid to a more liquid state. An example of a method for determining a gel crossover point is as follows: a Discovery HR-2 rheometer from TA Instruments, with a 40 mm parallel plate geometry on a flat stainless steel Peltier plate, may be used.The test can be performed at 25°C with an angular frequency test parameter of 1.0 rad / s and a logarithmic sweep: % strain from 0.1 to 1000.0%. 5 points per decade.
