Abstract
Description
Title of the invention: SPRAY COMPOSITIONS CONTAINING BIS-ETHYLHEXYLOXYPHENOL ME-THOXYPHENYL TRIAZINE FIELD OF THE INVENTION
[0001] The present disclosure relates to spray compositions comprising 2,4-bis-{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine (INCI name: bis-ethylhexyloxyphenol methoxyphenyl triazine), as well as methods of making and using such compositions. DISCUSSION OF THE CONTEXT
[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 wavelengths 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 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 filtration efficiency.
[0006] However, high levels of UV filters do not lend themselves to easy preparation of compositions with a stabilized and pleasant texture that can be sprayed. This is particularly true for compositions containing solid UV filters such as bis-ethylhexyloxyphenol methoxyphenyl triazine.
[0007] Consumers like sprayable sunscreen compositions because they are generally easy to apply and spread during application.
[0008] There remains a need in the art for improved spray compositions containing bis-ethylhexyloxyphenol methoxyphenyl triazine which have good UV protection capabilities in addition to good application and spray use properties.
[0009] Accordingly, one aspect of the present disclosure is a spray composition containing bis-ethylhexyloxyphenol methoxyphenyl triazine which has good UV protection properties in addition to good application and use properties. Summary of the invention
[0010] The present disclosure relates to spray compositions comprising bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT). Preferably, bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT or bemotrizinol) is added to the compositions in an amount effective to protect the keratinous material from UV radiation.
[0011] The present disclosure also relates to methods of making spray compositions comprising adding bis-ethylhexyloxyphenol methoxyphenyl triazine 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.
[0012] It is understood that both the foregoing general description and the following detailed description are provided for the purpose of example and explanation only and not as a limitation of 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.
[0017] As used herein, all proposed ranges are intended to include each specific point and range within the given ranges, and combinations of subranges therebetween. Thus, a range of 1 to 5 specifically includes integers in the range 1, 2, 3, 4, and 5, as well as subranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc., as well as all fractional numbers within the range such as 1.2, 2.3, 3.4, etc., and subranges including these fractional numbers such as 1.5 to 3.8, 2 to 4.3, 4.2 to 4.9, etc.
[0018] “Film former”, “film-forming polymer” or “film-forming agent” as used herein means a polymer or resin that is capable of leaving a film on the substrate to which it is applied, for example, after a solvent accompanying the film former has evaporated, been absorbed into, and / or dissipated on the substrate.

Non-limiting examples of substituents include atoms, such as hydrogen atoms or chlorine atoms, as well as functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalkyl groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen-containing groups, ester groups, thiol groups, sulfonate groups, thiosulfate groups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.
[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) are present in amounts not greater than 0.1% by weight, and "oil-free" means that oil(s) 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 for convenience. of example, not of 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 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).
[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”.
[0026] “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 the lips.
[0027] “Physiologically acceptable” means compatible with spraying and having a pleasant color, odor and feel, and which does not cause unacceptable discomfort (tingling or pulling) 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. "SPF" is a term 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 performed, 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. For such an assessment, polymethyl methacrylate (PMMA) plates can be used. An example of an acceptable protocol is currently undergoing ISO accreditation as ISO Committee Draft 23675.
[0031] The assessment of the sun protection factor (SPF) can also be carried out in vivo in accordance with the protocol 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.
[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] UVA protection assessment can also be measured in vitro with the Labsphere® spectrophotometer under conditions such as those discussed above in relation to SPF. The ISO 24443:2021 protocol describes such an in vitro method. Broad spectrum test procedures, in particular “critical wavelength” test procedures, are also available in 21 CFR Part 352 Subpart D § 352.72. In addition,
[0034] The FDA's broad spectrum test procedures include determining 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 / 26 / 02 / 2019 / 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 relates to the visual impact of a composition when applied to a keratinous material such as skin. The makeup result may relate to 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 viewed by 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 assessing long-lasting properties by any method known in the art for assessing 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 following 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] “Natural” as in the expression “natural compound” means any compound derived directly from a natural substance such as a plant without undergoing chemical modification.
[0043] “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.
[0044] “Synthetic compound” means any compound that is neither a natural compound nor a compound of natural origin.
[0045] “Room temperature” means approximately 20 to 25°C.
[0046] “Atmospheric pressure” means approximately 760 mmHg, i.e. approximately 105 pascals.
[0047] “UV filter” and “sunscreen agent” are used interchangeably in this request.
[0048] “UV efficacy” and “UV protection” are used interchangeably interchangeable in this application.
[0049] 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.
[0050] For the purposes of the present disclosure, the "fundamental and novel property" associated with the compositions, components and methods which "consist essentially of" the identified ingredients or actions is "spray angle, droplet distribution and / or product spray volume".
[0051] “Good application and use properties,” as used herein, refers to to the expected properties of a spray composition when dispensed from a suitable spray package. Desired characteristics in a spray composition which may be referred to herein as "use properties" include suitable spray angle, droplet distribution and product spray volume.
[0052] “Spray angle” or “spray cone angle” as used herein re presents the spray angle created when an actuator on the spray package is engaged to cause dispensing of the product from the packaging component. The spray angle can be measured visually by photographic examination of the droplets as they exit the packaging component. Alternatively, the spray angle can be determined by measuring the diameter of the spray pattern created on a vertical surface when the package is sprayed at a known distance from the vertical surface. The spray angle can be calculated as twice the inverse cosine of half the diameter of the spray pattern divided by the distance of the packaging component from the vertical surface.
[0053] “Droplet distribution” as used herein refers to a property of a spray composition when sprayed from a packaging component. Distribution may be assessed visually in terms of homogeneity or droplet size and distribution by spraying a spray composition at a controlled distance from a vertical surface and examining the droplet pattern created when the actuator is engaged for a predetermined time. Alternatively, droplet distribution may be measured at using laser detection equipment such as a Malvern Spraytec spray particle size analyzer, in which the droplet distribution can be reported as a volume or size distribution.
[0054] “Product spray volume” as used herein for the purpose of describing the Good use properties of a spray composition refers to the amount of product per unit time that is dispensed from a spray package, and is used interchangeably with "Product Spray Quantity". Product spray volume may be determined volumetrically or gravimetrically and is recorded as the amount of product dispensed over a controlled period of time.
[0055] The compositions of the present disclosure may be in any form suitable for use as a personal care composition, such as a stick, a paste, a cream, an anhydrous composition, an aqueous / alcohol-based composition, an emulsion (oil-in-water, water-in-oil, multiple emulsion such as oil-in-water-in-oil), a nanoemulsion, a thixotropic gel, a liquid, etc. These compositions may be used for any personal care purpose in cosmetic and / or dermatological products such as, for example, sunscreen, foundation, lip balms, lipsticks, concealers, mascaras, leave-in hair products, eye shadows, powders, etc.
[0056] 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 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.
[0057] 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.
[0058] All US patents or patent applications disclosed herein are expressly incorporated by reference in their entirety. Spray composition
[0059] According to the present disclosure, spray compositions comprising a UV (ultraviolet) absorbing system comprising 4-bis-{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine (INCI name: Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) are provided. Such spray compositions may be in any suitable form, and may be capable of being sprayed by any spraying means such as a pump spray device or an aerosol spray device. For aerosol spraying, the spray compositions of the present disclosure preferably comprise at least one propellant to facilitate atomization of the composition.
[0060] Suitable examples of acceptable composition forms include, but are not limited to, anhydrous compositions, aqueous / alcohol-based compositions, and emulsions having either an exterior aqueous phase (e.g., oil-in-water (o / w) emulsion) or an exterior oily phase (e.g., water-in-oil (w / o) emulsion). Such exemplary composition forms will be discussed in more detail below in connection with ingredients useful in such composition forms.
[0061] Preferred spray compositions of the present disclosure are fluid. "Fluid" particularly refers to a composition that is not solid at room temperature (25°C) and whose viscosity can be measured. The term "fluid" refers to a liquid composition that flows under its own weight at room temperature (25°C) and atmospheric pressure. Advantageously, a fluid composition according to the present disclosure has a complex rigidity modulus G* of less than 1000 Pa, preferably less than 400 Pa, preferably less than 200 Pa.
[0062] Preferably, the composition has, at 25°C, a viscosity of between 0.1 and 25 Pa.s and preferably between 0.5 and 22 Pa.s. A suitable method for measuring the viscosity is generally carried out at 25°C, using a Rheomat RM 180 viscometer equipped with a No. 3 rod or a No. 4 rod, depending on the working recommendations, the measurement being carried out after 10 minutes of rotation of the rod in the composition (after which a stabilization of the viscosity and the rotation speed of the rod is observed), at a speed of 200 rpm.
[0063] The spray compositions of the present disclosure may also not be fluid at room temperature and atmospheric pressure, but become fluid when a high shear rate is applied. Spray compositions that are fluid under high shear rate conditions are preferably sprayed using spray packages designed to exclude mixing of the spray composition and propellant. Examples of suitable spray packages include "bag-on-valve" packages and may comprise an outer canister and an inner bag, wherein the inner bag contains the spray composition and the space between the inner bag and the outer canister is pressurized using of any gas at a predetermined pressure. In such a "valve-to-bag" package, an actuator is connected so that when the actuator is engaged, the gas pressure between the outer canister and the inner bag is capable of compressing the inner bag and dispensing the spray composition.
[0064] Preferably, spray compositions suitable for dispensing via a bag valve package should be flowable (less than 0.1 Pa.s) at high shear rates (about 1000 / s). B is-ethylhexyloxyphenol methoxyphenyl triazine

[0161] Clays are silicates containing a cation that may be selected from calcium, magnesium, aluminum, sodium, potassium, and lithium cations, and mixtures thereof. As used herein, the term "hydrophilic clay" refers to a clay capable of swelling in water; this clay swells in water and upon hydration forms a colloidal dispersion.
[0162] Examples of such products include, but are not limited to, smectite family clays such as montmorillonites, hectorites, bentonites, beidellites and saponites, vermiculite family clays, stevensite and chlorites.
[0163] These clays can be of natural or synthetic origin.
[0164] Non-limiting examples of hydrophilic clays include smectites such as saponites, hectorites, montmorillonites, bentonites and beidellites and, in at least one embodiment, synthetic hectorites (also known as laponites), for example, the products sold by Laporte Company under the names Laponite XLG, Laponite RD and Laponite RDS (these products include, for example, sodium magnesium silicates and sodium lithium magnesium silicates); bentonites, for example, the product sold under the name Bentone HC by Rheox Company; magnesium aluminum silicates, which may be hydrated, for example, the products sold by Vanderbilt Company under the names Veegum Ultra, Veegum HS and Veegum DGT, and calcium silicates, such as the product in synthetic form sold by the company under the name Micro-cel C.
[0165] Organophilic clays are clays modified with chemical compounds that make the clay capable of swelling in solvent media.
[0166] The clay may be selected, for example, from montmorillonite, bentonite, hectorite, atapulgite, sepiolite and mixtures thereof. In one embodiment, the clay is selected from bentonite and hectorite.
[0167] The chemical compound used to modify the organophilic clay may be selected, for example, from quaternary amines, tertiary amines, amine acetates, imidazolines, amine soaps, fatty sulfates, alkyl aryl sulfonates, amine oxides, and mixtures thereof.
[0168] Suitable organophilic clays include, but are not limited to, stearalkonium clays such as stearalkonium hectorite and stearalkonium bentonites such as those sold as Bentone 27V by Elementis, Tixogel LG by United Catalyst, and Claytone AF and Claytone APA by Southern Clay; quatemium-18 bentonites such as those sold as Bentone 3, Bentone 38, Bentone 27 V CG, and Bentone 38V by Elementis, Tixogel VP by United Catalyst, and Claytone 34, Claytone 40, and Claytone XL by Southern Clay; and quaternium-18 / benzalkonium bentonites such as those sold under the names Claytone HT and Claytone PS by the Southern Clay company.
[0169] Hydrophilic fumed silicas can be obtained by high-temperature hydrolysis of a volatile silicon compound in an oxyhydrogen flame, producing a finely divided silica. Hydrophilic silicas have a large number of silanol groups on their surface. Such hydrophilic silicas are sold, for example, under the names Aerosil 130®, Aerosil 200®, Aerosil 255®, Aerosil 300® and Aerosil 380® by the company Degussa, and Cab-O-Sil HS-5®, Cab-O-Sil EH-5®, Cab-O-Sil LM-130®, Cab-O-Sil MS-55® and Cab-O-Sil M-5® by the company Cabot.
[0170] Hydrophobic fumed silicas can be obtained by modifying the surface of the silica via a chemical reaction which generates a reduction in the number of silanol groups, these groups being optionally substituted, for example, by hydrophobic groups.
[0171] The hydrophobic groups may be chosen, for example, from:
[0172] - trimethylsiloxyl groups, which can be obtained by treatment of silica sublimed in the presence of hexamethyldisilazane. Silicas treated in this way are known as "silica silylate" according to the CTFA (6th edition, 1995). They are sold, for example, under the references Aerosil R812® by the company Degussa, and Cab-O-Sil TS-530® by the company Cabot,
[0173] - dimethylsilyloxyl or polydimethylsiloxane groups, which can be obtained in particular by treatment of the sublimed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. The silicas thus treated are known under the name of “Silica dimethyl silylate” according to the CTFA (6th edition, 1995). They are sold, for example, under the references Aerosil R972® and Aerosil R974® by the company Degussa, and CAB-O-SIL TS-610® and CAB-O-SIL TS-720® by the company Cabot.
