Description

Title of the invention: COMPOSITIONS CONTAINING BIS-ETHYLHEXYLOXYPHENOL METHOXYPHENYL TRIAZINE AND ANTIOXIDANT SYSTEM 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) and an antioxidant system, as well as processes for the manufacture and use of such compositions. BACKGROUND DISCUSSION

[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 a detrimental change 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 a wavelength 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, leading to 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 product with high protection, it is generally necessary to combine a large number of sunscreens and / or a large quantity of UV filters to obtain high levels of filtration 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] It is advantageous to add antioxidants to products designed for application to keratinous material, particularly skin, because of their ability to neutralize free radicals and reactive oxygen species (ROS) generated under oxidative stress. Oxidative stress can be initiated by many extrinsic factors, including UV light. Consequently, it may be advantageous to add antioxidants in combination with UV filters in sun care compositions to try to reduce the effect of oxidative stress resulting from exposure to UV light.

[0008] UVA light is particularly involved in the ability to generate ROS and oxidative stress, which can be particularly problematic for the skin and can lead to skin damage.

[0009] Some antioxidants are not particularly stable against light, dissociating after exposure to light, which can result in less antioxidant activity available over time in a composition, ultimately resulting in lower quantities of compounds requiring antioxidant protection available in the composition to perform their desired or intended functionality.

[0010] There remains a need in the art for improved consumer skincare compositions that possess good antioxidant stability against light in addition to good UV protection properties.

[0011] Therefore, one aspect of the present disclosure is a composition which has good antioxidant stability against light in addition to having good UV protection properties. Summary of the invention

[0012] This disclosure relates to compositions comprising an antioxidant system and bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT or bemo-trizinol). Preferably, bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is present in the compositions in an amount effective in improving the photostability of the antioxidant system with respect to light.

[0013] The present invention also relates to methods of treating, caring for, protecting, enhancing the appearance and / or making up a keratinous material comprising applying compositions of the present invention to a keratinous material in a sufficient quantity to treat, care for, improve the appearance of the keratinous material and / or make it up.

[0014] This disclosure also relates to methods for improving the stability of the antioxidant system, in particular photostability, in compositions comprising an antioxidant system, 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 stability, in particular photostability, of the antioxidant system.

[0015] This disclosure also relates to manufacturing processes for compositions comprising the combination of bis-ethylhexyloxyphenol methoxyphenyl triazine and an antioxidant system in the compositions during the formation of the compositions. Preferably, bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is added to the compositions in an amount effective for improving the stability, especially the photostability, of the antioxidant system.

[0016] This disclosure also relates to methods for improving the stability of the antioxidant system against light in compositions comprising an antioxidant system, 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 stability of the antioxidant system in the compositions against light.

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

[0028] “Exempt” or “substantially exempt” or “devoid of”, as used herein, means While it is preferable that no quantity of the specific component 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, relative to the total weight of the composition.The same nomenclature applies to all other ingredients identified throughout the application and in this paragraph, such as UV filters and / or specific surfactants (the compositions of the invention "free of oxybenzone and / or octinoxate," "substantially free of oxybenzone and / or octinoxate," and "devoid of oxybenzone and / or octinoxate," as well as "free of surfactants," "substantially free of surfactants," and "devoid of surfactants" have meanings consistent with the description in this paragraph), even if this is not specifically described for each ingredient identified in the application. The examples cited of the use of such language as those in this paragraph are intended to be provided by way of example, and not as a 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] The term "keratinous materials" refers to 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 erythemal dose (MED) measured while wearing the composition and the MED measured on bare skin. The term "SPF" is well-known in the field 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 performed in vivo in accordance with ISO 24444:2019 "Cosmetics — Sun protection test methods — In vivo determination of 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] “UVA protection factor” refers to an index characterizing the UVA protection is ensured by its composition. For example, the FPUVA index. It can be measured in vivo using the "PPD" (Persistent Pigmentation) method of the ISO-24442:2022 protocol, which measures 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 mentioned 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] Broad-spectrum FDA test procedures, particularly "critical wavelength" test procedures, can also be found 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 / 2019-03019 / sunscreen-drug-products-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 from UVA1 (340 to 400 nm) and the protection against total UV radiation (UVB and UVA at 290 to 400 nm) calculated from the absorbance curve. This UVA1 / UV ratio would represent 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] “Long-lasting”, as used herein, refers to compositions where the colour or Other apparent properties remain identical or substantially identical to those at the time of application, to the naked eye, after a prolonged period, or after a particular stress such as immersion in water or rubbing. "Longevity" can be assessed by evaluating 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 skin and evaluating the color of the composition after a prolonged period. 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 compositions.The "long-lasting" can also be assessed using in vitro processes 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 stress such as immersion in water, incubation at high temperatures or the application of an abrasive process.

[0047] “Photosensitive”, as used herein, means any substance that can decompose or undergo a chemical transformation via a photochemical reaction pathway initiated by irradiation under UV or visible light. A composition containing a photosensitive compound can be expected to contain a lower amount of that compound after the composition has been exposed to UV or visible light.

[0048] The term “photostability,” as used here, refers to the probability of a substance contained in a composition decomposing or undergoing a chemical transformation via photochemical reaction pathways initiated by irradiation under UV or visible light. Photostability can often be used to describe the probability of a photosensitive substance decomposing or undergoing a chemical transformation via a photochemical reaction pathway after a composition has been exposed to UV or visible light.

[0049] The term "chemical stability," as used herein, refers to the probability that a substance contained in a composition will decompose or undergo a chemical transformation over time. In cases where the decomposition or chemical transformation of a substance contained in a composition is initiated or propagated by irradiation under UV or visible light, the term "chemical stability" is used interchangeably with "photostability."

[0050] “Photostabilizer”, as used herein, means a substance which, when it is added to a composition also containing a photosensitive substance, may reduce the likelihood that the photosensitive substance will undergo decomposition or chemical transformation when irradiated under UV or visible light.

[0051] “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.

[0052] “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.

[0053] “Synthetic compound” means any compound that is neither a natural compound nor a composed of natural origin.

[0054] “Room temperature” means approximately 20 to 25 °C.

[0055] The expression "atmospheric pressure" means a pressure of about 760 mmHg, that is about 105 pascals.

[0056] The “UV filter” and “sunscreen agent” are used interchangeably in this application.

[0057] The terms “UV efficiency” and “UV protection” are used interchangeably in this application.

[0058] “Antioxidant system” means at least one antioxidant in the compositions of this disclosure.

[0059] The compositions and processes of the present invention may include, consist of, or essentially consist 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 "essentially consist 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.

[0060] Similarly, the antioxidant protection system against light (“antioxidant system protection system”) of the disclosure compositions may “consist essentially of” bis-ethylhexyloxyphenol methoxyphenyl triazine.

[0061] For the purposes of this disclosure, the “new fundamental property” associated with compositions, components and processes that “consist essentially of” the identified ingredients or actions is “antioxidant system stability”

[0062] The expression "antioxidant system stability," as used here, refers to the chemical stability or photostability of an antioxidant system in a composition. Antioxidant system stability can be assessed by comparing the amount of antioxidant present in a composition before and after the application of a Stress factor. Alternatively, antioxidant system stability can be assessed by comparing the amount of antioxidant capacity to neutralize reactive oxygen species before and after the application of a stress factor, which can be measured following any specific or general reactive oxygen species measurement protocol. Appropriate reactive oxygen species measurement protocols may include, but are not limited to, HORAC, ORAC, and DPPH. Stress factors may include one or more factors such as UV light, visible light, temperature, time, oxygen exposure, exposure to acids or bases, or exposure to other substances. The term "antioxidant system stability" is used interchangeably with "photostable antioxidant system" when a stress factor includes exposure to UV or visible light.

[0063] The term “antioxidant system stability” refers to the level of an antioxidant system or the ability of the antioxidant system in a composition that has remained substantially active in the presence of the predetermined stress factor(s). By “remained substantially active,” it is understood that at least 50% of the target compound remained in the composition, preferably at least 55%, preferably at least 60%, preferably at least 70%, preferably at least 80%, preferably at least 85%, and preferably at least 90%, over the period of time.

[0064] 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.

[0065] Reference is made herein to trade names of materials including, but not limited to, polymers and optional components. The materials are not intended to be limited by the materials 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.

[0066] Unless otherwise stated, all percentages and ratios are calculated by weight. Unless otherwise stated, all percentages are calculated relative to 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 be excluding impurities, for example, excluding residual solvents or derivative products, which may be present in commercially available sources.

[0067] All US patents or patent applications described herein are expressly incorporated in their entirety by way of reference. COMPOSITION Antioxidant system
