Description

Title of the invention: COMPOSITIONS CONTAINING BIS-ETHYLHEXYLOXYPHENOL METHOXYPHENYL TRIAZINE AND AVOBENZONE FIELD OF INVENTION

[0001] This disclosure relates to compositions comprising 2,4-bis-{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine (INCI name: bis-ethylhexyloxyphenol methoxyphenyl triazine), avobenzone and, optionally, octinoxate, as well as processes for manufacturing and using such compositions. DISCUSSION OF THE CONTEXT

[0002] Radiation with wavelengths between 290 nm and 400 nm allows the human epidermis to tan, while radiation with wavelengths between 290 and 320 nm, known as UVB rays, hinders the development of a natural tan. Exposure is also likely to cause detrimental changes in the biomechanical properties of the epidermis, resulting in the appearance of wrinkles and leading to premature skin aging (i.e., photoaging).

[0003] UVA rays with wavelengths between 320 and 400 nm penetrate the skin more deeply than UVB rays. UVA rays cause immediate and persistent tanning of the skin. Daily exposure to UVA rays, even for a short period under normal conditions, can damage collagen and elastin fibers, resulting in changes in the skin's microrelief, 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 quantity of UV filters to achieve high levels of filtering efficiency.

[0006] However, high levels of UV filters do not lend themselves to the easy development of compositions having a stabilized and pleasant texture.

[0007] Octinoxate (octyl methoxycinnamate) and avobenzone (4-tert-butyl-4'-methoxydibenzoylmethane) are UV filters that are not particularly stable in light, degrading after light exposure, which can lead to a decrease in the availability of octinoxate and avobenzone over time. time and a reduction in the amounts of octinoxate and avobenzone available to provide their desired or intended protection against UV radiation. Furthermore, it has been reported that octinoxate negatively affects the stability of avobenzone when present in the same composition, further affecting the amount and functionality of avobenzone present in the composition.

[0008] There remains a need in the art of improved personal care compositions which exhibit good stability of octinoxate and avobenzone to light and have pleasant application properties (e.g., a non-greasy feel).

[0009] Therefore, one aspect of the present disclosure is compositions which have good stability of avobenzone to light and exhibit pleasant application properties (e.g., a non-greasy feel).

[0010] Another aspect of the present disclosure is compositions that possess good light stability of octinoxate and avobenzone and exhibit pleasant application properties (e.g., a non-greasy feel). Summary of the invention

[0011] This disclosure relates to compositions comprising avobenzone and bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT or bemotrizinol). Preferably, the compositions further comprise octinoxate. Preferably, bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is present in the compositions in an amount effective in improving the photostability of avobenzone to light, as well as in improving the photostability of octinoxate to light (if octinoxate is present).

[0012] This disclosure also relates to processes for the treatment, care, protection, enhancement of appearance and / or makeup of keratinous material, including the application of compositions of this disclosure to keratinous material in sufficient quantity to treat the keratinous material, care for it, enhance its appearance and / or make it up.

[0013] This disclosure also relates to methods for improving the photostability of avobenzone and octinoxate (where applicable), in compositions comprising avobenzone and optionally octinoxate, wherein the methods include the addition of bis-ethylhexyloxyphenol methoxyphenyl triazine to the compositions during the formation of the compositions in an amount sufficient to improve the photostability of avobenzone and octinoxate (where applicable).

[0014] This disclosure also relates to processes for manufacturing compositions comprising the combination of bis-ethylhexyloxyphenol methoxyphenyl triazine, avobenzone, and optionally octinoxate in the compositions during the formation of the compositions. Preferably, the bis-ethylhexyloxyphenol me- Thoxyphenyl triazine (BEMT) is added to the compositions in an effective amount to improve the light photostability of avobenzone and octinoxate (where applicable).

[0015] This disclosure also relates to methods for improving avobenzone and, optionally, improving the light stability of octinoxate in compositions comprising avobenzone and, optionally, octinoxate, wherein the methods include the addition of bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) to the compositions during the formation of the compositions in an amount sufficient to improve the light stability in the avobenzone and octinoxate compositions (where applicable).

[0016] This disclosure also relates to methods for improving the stability of avobenzone in compositions that also contain octinoxate, wherein the methods include adding bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) to the compositions during the formation of the compositions in an amount sufficient to improve the stability of avobenzone in the compositions that also contain octinoxate.

[0017] It must be understood that both the preceding general description and the detailed description that follows are merely illustrative and explanatory and do not limit disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0018] In the following description and the claims annexed thereto, it shall be understood that the terms used have their ordinary and usual meanings in the art, unless otherwise specified.

[0026] “Non-volatile”, as used herein, means having a flash point greater than approximately 115 °C.

[0027] “Polymer” as used herein means a compound that is made up of at least two monomers.

[0028] “Exempt” or “substantially exempt” or “devoid of” as used herein This means that although it is preferable for no quantity of the specific component to be present in the composition, it is possible for very small quantities of it to be present in the compositions of the disclosure, provided that these quantities 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 quantity (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 one or more oils are present in quantities not exceeding 0.1% by weight, and "oil-free" means that one or more oils are present in quantities not exceeding 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-free," "substantially oxybenzone-free," and "oxybenzone-free," as well as "surfactant-free," "substantially surfactant-free," and "surfactant-free" have meanings consistent with the discussion in this paragraph), even if they are not specifically mentioned for each identified ingredient. The examples of the use of such language, such as those in this paragraph, are intended to be provided by way of example, not limitation.

[0029] “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 organic UV filters such as avobenzone, octocrylene, benzophenones, benzotriazoles and merocyanines as well as mineral UV filters such as zinc oxide (ZnO) and titanium dioxide (TiO2).

[0030] “Anhydrous” as used here means that the compositions of the disclosure contain less than 3% water, which means that compositions may also contain less than 2% water, and less than 1% water, as well as being "water-free", "substantially water-free" and "water-free", as defined above.

[0031] "Keratinous materials" means nails (fingernails and / or toenails), skin such as the body, face and eye area, scalp, keratinous fibers such as eyelashes, eyebrows and hair, and mucous membranes such as lips.

[0032] “Physiologically acceptable” means compatible with keratinous materials and having a pleasant color, smell and feel, and which does not cause unacceptable discomfort (tingling or pulling) likely to discourage a consumer from using the composition.

[0033] “UV protection efficiency” or “filtering efficiency” in the context of this disclosure, is evaluated from one or more factors FPS, UVAPF, critical wavelength and UVA-l / UV ratio.

[0034] The "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 erythematous 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).

[0035] The evaluation of the SPF (Sun Protection Factor) can be carried out, for example, in vitro with a spectrophotometer from Labsphere (North Sutton, NH, USA). In such an evaluation, the plate is the material onto which the composition under test is applied. For such an evaluation, polymethyl methacrylate (PMMA) plates can be used. An example of an acceptable protocol is currently undergoing ISO accreditation under the name ISO Committee Draft 23675.

[0036] 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 U.S. 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.

[0037] The "UVA protection factor" (UPF) refers to an index characterizing the UVA protection provided by a composition. For example, the UPF index can be measured in vivo according to the "PPD" (Persistent Pigment Darkening) method of the ISO-24442:2022 protocol, measuring the skin color observed 2 to 4 hours after UVA exposure. It can also be determined according to FDA protocols, as described in 21 CFR Part 352 Subpart D § 352.72 as discussed above in relation to SPF.

[0038] UVA protection can also be assessed in vitro using the Labsphere® spectrophotometer under conditions such as those mentioned above in relation to the SPF. ISO 24443:2021 describes such an in vitro procedure.

[0039] FDA broad-spectrum test procedures, particularly "critical wavelength" test procedures, are also available in 21 CFR Part 352 Subpart D § 352.72. In addition, 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-products-for-over-the-counter-human-use. In the test described in the monograph, known as the Boots adaptation of the Diffey / Robson test method, a ratio is generated between the protection offered 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 represents the product's score in the in vitro test.

[0040] According to this disclosure, the compositions in this disclosure preferably have one or more of the following properties:

[0041] The compositions have a critical wavelength as determined by FDA critical wavelength procedures of at least 370 nm;

[0042] The compositions have an FPS value of at least 15, preferably at least 30, preferably at least 50 and preferably at least 70;

[0043] The compositions have an FPUVA / FPS ratio of at least 1 / 3 and, preferably, of at least 2 / 5 and / or

[0044] The compositions have a UVA1 / UV ratio of 0.7 or more, preferably 0.75 or more and preferably 0.8 or more.

[0045] The "makeup result" as used herein refers to the visual impact of a composition when applied to a keratinous material such as the skin. The makeup result may refer to the apparent color of the product after application to a keratinous material or to 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.

[0046] "Longevity," 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 a prolonged period or after a particular stress event such as immersion in water or rubbing. "Longevity" can be assessed by evaluating the longevity properties using any method known in the art for evaluating such properties. For example, longevity can be assessed by a test involving the application of a composition to a keratinous material such as the lips and evaluating the color of the composition after a prolonged period of time. For example, the color of a composition can be evaluated immediately after application to a keratinous material such as skin, and these characteristics can then be re-evaluated and compared after a certain time.Furthermore, these characteristics can be evaluated against other compositions, such as commercially available ones. "Longevity" can also be assessed using in vitro methods on non-keratinous substrates such as polymethyl methacrylate (PMMA), in which properties such as color, transparency, or in vitro FPS can be evaluated before and after a period of time or a stress factor such as immersion in water, incubation at high temperatures, or the application of an abrasive technique.

[0047] “Natural” as in the expression “natural compound” means any compound derived directly from a natural substance such as a plant without having undergone chemical modification.

[0048] “Compound of natural origin” means any compound derived from a natural 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.

[0049] “Synthetic compound” means any compound that is neither a natural compound nor a composed of natural origin.

[0050] “Room temperature” means approximately 20-25 °C.

[0051] “Atmospheric pressure” means approximately 760 mmHg, i.e. approximately 105 pascals.

[0052] “UV filter” and “sunscreen agent” are used interchangeably in the present request.

[0053] “UV efficiency” and “UV protection” are used in a manner interchangeable in this application.

[0054] “Photo stability” and “light stability” are used interchangeably changeable in this application.

[0055] The compositions and processes of this disclosure may include, consist of, or consist essentially of the essential elements and limitations of the disclosure described herein, together with 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 and avobenzone alone, or bis-ethylhexyloxyphenol methoxyphenyl triazine, avobenzone, and octinoxate alone, or bis-ethylhexyloxyphenol methoxyphenyl triazine, avobenzone, and optionally octinoxate in combination with zinc, titanium, and / or cerium oxides, and / or one or more additional organic UV filters.

[0056] Similarly, the protection of avobenzone and octinoxate (if any) against light from the "avobenzone and octinoxate protection system (if any)" of the disclosure compositions may "consist essentially of" bis-ethylhexyloxyphenol methoxyphenyl triazine. If octinoxate is not present in the compositions, it may be referred to as an "avobenzone protection system".

[0057] Similarly, the protection of avobenzone against degradation caused by the octinoxate system (“avobenzone degradation protection system”) of the disclosure compositions may “consist essentially of” bis-ethylhexyloxyphenol methoxyphenyl triazine.

[0058] For the purposes of this disclosure, the "fundamental novel property" associated with avobenzone-related (and optionally octinoxate-related) compositions, components and processes that "consist essentially of" identified ingredients or actions is "light stability" of avobenzone (and, optionally, octinoxate).

[0059] For the purposes of this disclosure, the "fundamental novel property" associated with avobenzone-related compositions, components and processes that "consist essentially of" identified ingredients or actions is "the light stability and octinoxate-induced degradation of avobenzone"

[0060] “Stability of avobenzone in light” and “stability of avobenzone in light and to degradation caused by octinoxate” as used here means that stability against degradation over time after exposure to UV radiation is limited, so the amount of avobenzone (optionally octinoxate) available for application has remained substantially constant over time. The stability of avobenzone The stability of avobenzone (optionally octinoxate) can be assessed by determining the amount of avobenzone (optionally octinoxate) present in a composition at an initial time (time = T0) and comparing this determination to a determination of the amount of avobenzone (optionally octinoxate) present in the composition at a later date after exposure of the composition to a predetermined UV dose. The stability of avobenzone (optionally octinoxate) can also be assessed by comparing the absorption spectra before and after a composition containing avobenzone (optionally octinoxate) is irradiated with a predetermined amount of UV light.Irradiation of any composition containing avobenzone (optionally octinoxate) can be carried out using a single wavelength, preferably the peak absorbance in the UV region for the UV filter (lambda max), or over a range of wavelengths as provided by a solar simulator or other similar irradiation method. When a comparison of absorption spectra is used to assess the stability of avobenzone (optionally octinoxate), it may be convenient to compare the in vitro FPS values ​​measured before and after irradiation under a single wavelength or a range of UV light wavelengths.

[0061] By "remained substantially constant" is meant that at least 70% of the target compound remained in the composition, preferably at least 80%, preferably at least 85%, and preferably at least 90%, over time. When the in vitro FPS or other calculated measurements are used to assess the stability of the target compound, "remained substantially constant" should be understood as meaning that at least 70% of the in vitro FPS is maintained for the composition after irradiation, preferably at least 80%, preferably at least 85%, and preferably at least 90%, compared to the in vitro FPS before irradiation.

[0062] The compositions of this disclosure may be in any form suitable for use as a personal care composition, such as a stick, paste, cream, anhydrous composition, emulsion (oil-in-water, water-in-oil, multiple emulsion such as water-in-oil-in-water), nanoemulsion, gel, liquid, solid, etc. These compositions may be used for all personal care purposes in cosmetic and / or dermatological products such as, for example, sunscreen, foundation, lip balms, lipsticks, concealers, mascaras, leave-in hair products, eyeshadows, powders, etc.

[0063] 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 to those described and referenced herein by a particular trade name. Equivalent materials (for example, those obtained from a different source under a different name or catalogue (reference) number) to those referenced by a trade name may be substituted for and used in the processes described and claimed herein.

[0064] Unless otherwise stated, all percentages and ratios are calculated by weight. Unless otherwise stated, all percentages are calculated on the basis of the total weight of a composition. All component or composition levels refer to the active level of that component or composition and are understood to exclude impurities, for example, residual solvents or by-products, which may be present in commercially available sources.

[0065] All US patents or patent applications disclosed herein are expressly incorporated by reference in their entirety. COMPOSITION
