Description

[0001] Cross-references to related applications This application claims priority to U.S. Patent Application No. 18 / 345,554, filed June 30, 2023. This application also claims priority to French Patent Application No. 2311124, filed October 16, 2023. Technical Field

[0002] This invention relates to an oil-in-water (o / w) emulsion (composition) comprising at least one hydrophobically modified polysaccharide compound and at least one aqueous film-forming agent, and to methods and kits for incorporating such emulsion compositions in one or more containers or during application. The compositions possess beneficial cosmetic properties, including, for example, as a primer or setter composition to achieve good or improved makeup retention, water and / or sebum resistance, and / or transfer resistance of the composition applied alone.

[0003] Background Discussion Currently, in the market for care and cosmetic products using keratin materials, many products claim all-day wear, resisting external factors such as water, sebum, and mechanical friction (waterproof mascara, food-resistant lipstick, long-lasting foundation). Long-lasting products for lips, eyelashes, eyebrows, or face that can be used at home are primarily based on synthetic coating polymers in the presence of organic solvents. For makeup lip and face compositions, compositions containing unmodified silicone resins as film-forming agents are known, such as compounds with INCI names: trimethylsiloxysilicate or polypropylsilsesquioxane, or silicone acrylate copolymers, such as products with INCI names: acrylate / polytrimethylsiloxymethacrylate copolymer. Long-lasting cosmetic products for eyelash and / or eyebrow applications (mascaras, eyeliners) typically use waxes or film-forming polymer particles (i.e., styrene / acrylate copolymers) in latex-type aqueous suspensions as film-forming agents.

[0004] Beyond these long-lasting products, the current trend is toward semi-permanent makeup. Specifically, in recent years, regular makeup products have faced competition from the semi-permanent makeup market offered by professional salons. This is evident in cosmetics for the eyes (semi-permanent mascara, permanent eyelash makeup, eyelash extensions, etc.), eyebrows (semi-permanent pigmentation known as micro-blading), skin tones (freckles, beauty marks, or full-face treatments, brightening or healthy-looking skin), and lips (semi-permanent tattoos). This new trend is driving consumers to seek increasingly longer-lasting results for greater practicality (avoiding daily makeup and removal, waking up to a healthy-looking skin tone, etc.).

[0005] The object of this invention is to provide a composition that provides excellent long-lasting cosmetic effect, particularly cosmetic color on keratinous materials (skin, lips, nails, hair, eyelashes, eyebrows), which can prolong the duration of the cosmetic composition on keratinous materials and improve the makeup retention of the cosmetic composition on keratinous materials, as well as its resistance to one or more of external forces such as mechanical friction, water, sweat and perspiration, sebum, oil, etc.

Summary of the Invention

[0008] This invention relates to an oil-in-water (o / w) emulsion (composition) comprising at least one hydrophobically modified polysaccharide compound and at least one aqueous film-forming agent. Preferably, the composition is for application to the skin. Most preferably, the composition is a setting or pre-makeup composition, and / or in gel form. Also preferably, the composition further comprises at least one gelling agent and / or at least one active agent.

[0009] The present invention also relates to a method of fixing a makeup composition (e.g., a composition containing a colorant, such as foundation) and / or priming a makeup composition with keratin material by applying the composition of the present invention to a keratin material (pre-makeup) and / or to a makeup composition previously applied to a keratin material (setting makeup) in an amount sufficient to prime the makeup composition and / or sufficient to fix a previously applied makeup composition to the keratin material.

[0010] The present invention also relates to a kit containing, in one or more containers within the kit, a separate composition comprising: (A) at least one composition of the present invention, particularly a setting or pre-makeup composition for cosmetics, comprising at least one hydrophobically modified polysaccharide compound and at least one aqueous film-forming agent; and (B) at least one cosmetic composition comprising at least one colorant.

[0013] It should be understood that the foregoing general description and the following detailed description are merely exemplary and illustrative, and do not limit the invention. Invention Details In the following detailed description of the invention and the appended claims, it is to be understood that, unless otherwise stated, the terms used have their ordinary and customary meaning in the art.

[0015] As used in this article, “approximately” means within 10% of the indicated figure (for example, “approximately 10%” means 9%-11%, and “approximately 2%” means 1.8%-2.2%).

[0016] As used in this article, "a / species" or "a / kind" means "at least one / kind".

[0017] "At least one" means one or more species, and therefore includes individual components as well as mixtures / combinations.

[0018] As used herein, all ranges provided are intended to include each specific range within a given range as well as combinations of subranges between given ranges. Thus, the range 1-5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.

[0019] As used herein, “film-forming agent,” “film-forming polymer,” or “film-forming reagent” refers to a polymer or resin that leaves a film on the substrate to which it is applied, for example, after the solvent accompanying the film-forming agent has evaporated, been absorbed into the substrate, and / or dissipated on the substrate.

[0020] The “wax” used in this article is a lipophilic aliphatic compound that is solid at ambient temperature (25°C) and reversibly changes from solid to liquid, has a melting temperature of over 30°C and, for example, over 45°C, and a hardness of over 0.5 MPa at ambient temperature.

[0021] The terms "surfactant" and "emulsifier" are used interchangeably throughout this instruction manual.

[0022] As used herein, “substituted” means containing at least one substituent. Non-limiting examples of substituents include atoms such as oxygen and nitrogen atoms, and functional groups such as hydroxyl, ether, alkoxy, acyloxyalkyl, alkenyl, polyoxyalkyl, carboxylic acid, amino, acylamino, amide, halogen-containing groups, ester, thiol, sulfonate, thiosulfate, siloxane, and polysiloxane. One or more substituents may be further substituted.

[0023] As used in this article, “volatility” refers to having a flash point of less than approximately 115°C.

[0024] As used in this article, “non-volatile” means having a flash point greater than approximately 115°C.

[0025] As used in this article, "polymer" refers to a compound consisting of at least two monomers.

[0026] As used herein, “matte” in the context of a composition refers to a composition that has little to no light reflection. For example, a matte composition may have an average gloss property measured at 60° of less than or equal to 10, such as 9, preferably less than or equal to 8, 6, 5, 4, or 1, including all ranges and subranges in between, such as 1-10, 1-5, 2-10, 3-8, less than 1, less than 3, less than 5, etc. The film to be tested can be deposited onto a substrate (e.g., a black coated panel P121-10N or an opaque card BYK No. 2810) using a doctor blade (e.g., with a thickness of 1 mil, 3 mil, or 6 mil) and an automated doctor blade coater. The film is then dried at room temperature and analyzed using a micro-TRI-gloss meter (BYK: micro-TRI-gloss) at a 60° angle.

[0027] As used herein, “free from,” “substantially free from,” or “lacking” means that although a certain amount of a particular component is preferably absent in the composition, it may be present in very small amounts in the compositions of the present invention, provided that these amounts do not substantially affect at least one, preferably most, advantageous properties of the conditioning compositions of the present invention. Thus, for example, based on the total weight of the composition, “free from colorant” means that an effective amount (i.e., more than a trace amount) of colorant is omitted from the composition (i.e., approximately 0% by weight), “substantially free from colorant” means that the colorant is present in an amount not greater than 0.1% by weight, and “lacking colorant” means that the colorant is present in an amount not greater than 0.25% by weight. The same nomenclature applies to all other components identified throughout this application and in this paragraph, such as silicone oil (the compositions of the present invention that are “free from silicone oil,” “substantially free from silicone oil,” and “lacking silicone oil” have the same meaning as discussed in this paragraph), even if each identified component is not specifically discussed. Therefore, for example, based on the total weight of the composition, "free of phenyl silicone oil" means phenyl silicone oil (i.e., approximately 0% by weight) with an effective amount (i.e., effective amount for inhibiting matting) omitted from the composition, "substantially free of phenyl silicone oil" means that phenyl silicone oil is present in an amount not greater than 0.25% by weight, and "lacking phenyl silicone oil" means that phenyl silicone oil is present in an amount not greater than 0.5% by weight. The same nomenclature applies to all other components identified throughout this application and in this paragraph, such as (1) matting filler ("free of matting filler", "substantially free of matting filler", and "lacking matting filler" of the composition of the invention) and (2) additional film-forming agents other than the hydrophobically modified polysaccharide compound and the aqueous film-forming agent ("free of additional film-forming agent", "substantially free of additional film-forming agent", and "lacking additional film-forming agent" of the composition of the invention), having the same meaning as discussed in this paragraph, even if each identified component is not specifically discussed. Examples of the use of such language discussed (such as those in this paragraph) are intended to be exemplary and not limiting.

[0028] As used herein, "makeup result" means that, after an extended period of time, the color of the composition remains the same or substantially the same as when it was applied, as observed by the naked eye. "Makeup result" can be assessed by evaluating long-term makeup retention properties using any method known in the art for assessing this property. For example, long-term makeup retention can be assessed by a test involving applying the composition to a keratinous material (such as lips) and evaluating the color of the composition after an extended period of time. For example, the color of the composition can be assessed immediately after application to a keratinous material such as lips, and these properties can subsequently be reassessed and compared after a certain amount of time. Furthermore, these properties can be evaluated relative to other compositions (such as commercially available compositions).

[0029] "Keratin material" refers to natural nails, lips, skin such as the face, body, hands and the area around the eyes, as well as keratin fibers such as human hair, eyelashes, eyebrows and body hair, and synthetic additives such as false eyelashes, false eyebrows and false nails.

[0030] "Physiologically acceptable" means compatible with keratin materials and having a pleasant color, smell, and feel, without causing any unacceptable discomfort (tingling or tightness) that would discourage consumers from using the composition. The compositions of this invention may be in the form of a gel composition.

[0031] "Gel composition" refers to a composition that does not flow like a liquid when applied to a substrate, and has a three-dimensional network that inhibits the spread or dripping of the composition onto or off the substrate by gravity after application for a short period of time (e.g., less than 10 seconds). G' (storage modulus) is higher than G" (loss modulus) across the entire strain range up to 300% strain. Preferably, G' (storage modulus) is higher than G" (loss modulus) at low strains, but the gel exhibits a crossover point at >0.1% strain, preferably >1% strain, and preferably less than 200% strain, preferably less than 150% strain.

[0032] The "gel crossover point" (sol / gel point) refers to the point where G (loss modulus) and G' (storage modulus) intersect, reported as a percentage of strain. This is the point where the composition changes from a more solid to a more liquid state. An example of a method for determining the gel crossover point is as follows: G (loss modulus) and G' (storage modulus) are determined using a TA Instruments Discovery HR-3 rheometer with a 40 mm parallel plate geometry on a stainless steel Peltier plate. The test can be performed at 25°C with the following test parameters: angular frequency of 1.0 rad / s, and logarithmic scan: strain % 0.01 to 1000.0%. Five points are taken every ten octaves. Results are reported as a percentage of strain.

[0033] "Natural compound" refers to any compound that is directly derived from natural substances (such as plants) without any chemical modification.

[0034] "Naturally derived compounds" refers to any compound derived from a natural compound that has undergone one or more chemical modifications (e.g., through organic synthesis reactions) without altering the properties of the natural compound.

[0035] "Synthetic compound" refers to any compound that is not a natural compound or a compound of natural origin.

[0036] "Room temperature" refers to 25℃.

[0037] "Atmospheric pressure" refers to 760 mmHg, which is 10 5 Pascal.

[0038] The compositions and methods of the present invention may comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful. For example, an aqueous solvent system may consist “essentially” of water and a C2-C5 monohydric alcohol, and / or a film-forming system of the composition may consist essentially of a hydrophobically modified polysaccharide compound and an aqueous film-forming agent; similarly, an oil-phase film-forming system may consist essentially of a hydrophobically modified polysaccharide compound.

[0039] For the purposes of this invention, the "fundamental and novel property" associated with compositions, components, and methods that are "consistent" with the identified ingredients or effects is resistance to transfer.

The inventors do not intend to be limited by the materials described and referenced under any particular trade name. In the methods described and claimed herein, materials equivalent to those referenced under the trade name may be substituted and used (e.g., those obtained from different sources under different names or catalog (reference) numbers).

[0041] Unless otherwise stated, all percentages and ratios are by weight. Unless otherwise stated, all percentages are based on the total weight of the composition.

[0147] Example 2 – Test Plan The resistance to migration can be determined as follows.

[0148] Makeup compositions (e.g., foundations such as L'Oreal Paris Makeup True Match Liquid Foundation) are applied in controlled amounts (e.g., 0.020 g) to a controlled area (e.g., a 3 cm × 3 cm square) onto a keratin material (e.g., skin). Allow to stand for 5–15 minutes until the composition is dry.

[0149] Apply a controlled amount (e.g., the same amount applied as the makeup composition, such as 0.020 g) of the test composition (setting agent) onto the applied makeup composition and allow it to dry. If the test composition (setting agent) is not applied to the makeup, the transfer resistance of the makeup itself (without the setting composition) can be compared with the transfer resistance when the setting composition and the makeup composition are used together.

[0150] The area was then rubbed a determined number of times (e.g., 5 or more times) with a white cotton ball / pad sample to assess the resistance to transfer of the makeup composition to the ball / pad sample after such rubbing. Resistance to transfer can be assessed by measuring the difference in the amount of makeup composition transferred to the cotton ball / pad sample with and without the applied setting composition. Resistance to transfer is rated on a scale of 1 to 5, where 1 = minimal improvement in resistance to transfer of the makeup composition to the cotton ball / pad sample; 3 = moderate improvement in resistance to transfer of the makeup composition to the cotton ball / pad sample; and 5 = significant improvement in resistance to transfer of the makeup composition to the cotton ball / pad sample, with little or no transfer of the makeup composition to the cotton ball / pad sample.

[0153] Examples 3E-3J represent inventive compositions containing a specified amount and / or ratio of a hydrophobically modified branched starch compound and an aqueous film-forming agent.

[0154] The transfer resistance of the commercial foundation + prepared setting composition was determined according to the scheme in Example 2: As can be seen, compared with comparative setting compositions that contain little or no hydrophobically modified branched starch compounds and / or aqueous film-forming agents, the setting compositions of the present invention exhibit superior transfer resistance when used in combination with commercially available foundation products.

[0155] Example 4 Similar to Example 3, according to the scheme in Example 2, the following inventive setting composition AI was prepared and used as the setting composition for L'Oreal Paris Makeup True Match Liquid Foundation to determine its transfer resistance: .

[0156] Similar to Example 3, the setting composition AI of the present invention exhibits superior transfer resistance when used in conjunction with commercially available foundation products, compared to a comparative setting composition that contains little or no hydrophobically modified branched starch compound and / or aqueous film-forming agent.
