Abstract
Description
Title of the invention: COMPOSITIONS CONTAINING A UV-ABSORBING SYSTEM INCLUDING BIS- ETHYLHEXYLOXYPHENOL METHOXYPHENYL TRIAZINE AND IRON OXIDE FIELD OF INVENTION
[0001] This disclosure relates to compositions comprising a light-absorbing system comprising 2,4-bis-{ [4-(2-ethylhexyloxy)-2-hydroxy]-phenyl}-6- (4-methoxyphenyl)-1,3,5-triazine (INCI name: bis-ethylhexyloxyphenol methoxyphenyl triazine) and iron oxide, 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, called UVB rays, hinders the development of a natural tan. Exposure is also likely to cause a detrimental alteration of the biomechanical properties of the epidermis, resulting in the appearance of wrinkles 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] Studies have also implicated visible light, in particular high-energy visible (HEV) light, for its propensity to cause oxidative stress on keratinous materials, especially the skin, leading to damage such as skin lesions.
[0006] 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 filtration efficiency.
[0007] However, high levels of UV filters do not lend themselves to easy processing stable compositions with a pleasant texture, and it remains difficult to find a balance between UVA and UVB protection.
[0008] There remains a need in art for improved compositions which have organic UV filters and offer pleasant application properties (e.g., without greasy feeling) as well as protection against UVA, UVB and visible light.
[0009] Accordingly, one aspect of the present disclosure is a composition which has organic UV filters and has pleasant application properties (e.g., non-greasy feel) and UV protection properties. Summary of the invention
[0010] This disclosure relates to compositions comprising a light-absorbing system comprising iron oxide and bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT or bemotrizinol).
[0011] 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.
[0012] This disclosure also relates to methods of manufacturing compositions comprising a light-absorbing system comprising iron oxide and bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) by combining bis-ethylhexyloxyphenol methoxyphenyl triazine and iron oxide in the compositions during the formation of the compositions.
[0013] 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
[0014] 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.

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 oil(s) are present in quantities not exceeding 0.1% by weight, and "oil-free" means that oil(s) 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, for example, specific UV filters and / or surfactants (the compositions in the disclosure that are "free of oxybenzone and / or octinoxate", "substantially". The phrases "free from oxybenzone and / or octinoxate" and "free from oxybenzone and / or octinoxate," as well as "free from surfactants," "substantially free from surfactants," 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 such language used in this paragraph are intended to be illustrative, not limiting.
[0025] “UV Filters” as used herein means approved active sunscreen 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] “Keratinous materials” refers to nails (fingernails and / or nails) toes), skin such as the body, face and eye area, scalp, keratinous fibers such as eyelashes, eyebrows and hair, and mucous membranes such as lips.
[0031] “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.
[0032] “UV protection efficiency” or “filtration efficiency” in the context of the This disclosure is evaluated based on one or more factors including FPS, FPUVA, critical wavelength, and UVA-I / UV ratio.
[0033] 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).
[0034] 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.
[0035] 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 the sun protection factor (SPF).” It can also be determined according to 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.
[0036] “UVA protection factor” refers to a characteristic index assessing the UVA protection provided by a composition. For example, the UVA protection factor (UPF) 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 again in 21 CFR Part 352 Subpart D § 352.72 as mentioned above in relation to FPS.
[0037] 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.
[0038] 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 / 2019-03019 / 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 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 would represent the product's score in the in vitro test."
[0039] Visible light protection can be assessed under clinical conditions by comparing the characteristics of keratinous material, such as skin texture, skin tone, or skin lesions, before and after controlled exposure to visible light. Alternatively, visible light protection can be measured according to other protocols reported in the literature that track the changes in skin biomarkers or similar substrates over controlled exposures to visible light. Alternatively, visible light protection can be measured in vitro using a colorimeter or estimated by comparing the absorbance spectra of compositions in the ranges from approximately 400 nm to approximately 800 nm.
[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 makeup application The position when applied to a keratinous material such as skin. The makeup result can refer to the apparent color of the product after application to a keratinous material or an optical effect such as shine, blurring of fine lines and imperfections, or a concealing effect on pores or blemishes after application of the product to the keratinous material.
[0046] "Longevity," as used here, 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 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 ones. "Longevity" 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 or 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 to 25 °C.
[0051] “Atmospheric pressure” means 760 mmHg, that is about 105 pascals.
[0052] “UV filter” and “sunscreen agent” are used interchangeably in the present request.
[0053] The expressions "UV effectiveness", "UV protection" and "UV effectiveness" are used interchangeably in this application.
[0054] “Light-absorbing” or “light-protecting” as used herein refer to compositions or substances or mixtures of substances that are capable of absorbing or attenuating one or more of the following: UVA, UVB or visible light.
[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 iron oxide.
[0056] For the purposes of this disclosure, the "fundamental novel property" associated with compositions, components and processes that "consist essentially of" identified ingredients or actions is "UVA protection indicated by the FPUVA / FPS and UVA1 / UV ratios".
[0057] 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.
