Description
Title of the invention: EYELASH COATING COMPOSITIONS FOR FALSE EYELASHES FIELD OF THE INVENTION
[0001] The present invention relates to eyelash coating compositions comprising water, at least one film-forming agent, at least 8% structuring agent(s), and at least one surfactant. The eyelash coating compositions of the present invention possess sufficient adhesiveness and rapid drying properties (e.g., 1 minute or less) such that, after application of the compositions to the eyelashes, false eyelashes or artificial eyelashes may be adhered to the eyelashes by, via, or using the applied eyelash coating compositions of the present invention by placing the false eyelashes or artificial eyelashes on the applied composition and allowing the eyelash coating composition to dry.Further, the eyelash coating compositions may be applied to false (artificial) eyelashes or natural (real) eyelashes, if desired, to condition or make up the eyelashes and, as such, the eyelash coating compositions of the present invention may be versatile. discussion of the context
[0002] Mascaras typically contain wax that can add body and volume to the composition. Mascaras may also contain surfactants, particularly when in the form of emulsions. However, mascara formulations are typically created to minimize or smother the full effect of the properties of these ingredients, if present, in order to achieve the specific desired properties of the formulated mascara, such as volume, lengthening, ease of removal, etc.
[0003] Furthermore, mascara compositions are generally of two types: (1) long-lasting, waterproof mascaras that are anhydrous or (2) washable mascaras (e.g., washable with soap and water) that contain water. In general, waterproof mascaras are not easy to remove, and washable mascaras are not particularly durable.
[0004] False (artificial) eyelashes are typically applied to natural (real) eyelashes using adhesives (glue) or magnets.
[0005] For example, document US 2016 / 0206031 discloses the use of magnetic materials, and document US 2019 / 0261715 discloses magnetic materials in an eyeliner-type composition.
[0006] With respect to adhesives or glue, US 2017 / 0027844, WO 2020 / 172746, and WO 2019 / 003454 are examples of references disclosing the use of such compounds for false (artificial) eyelashes.
[0007] Document US 9,320,920 discloses compositions for making up eyelashes, including false (artificial) eyelashes.
[0008] There remains a need for improved cosmetic compositions having improved cosmetic properties, in particular mascaras and in particular water-containing mascaras, which may be useful for attaching false (artificial) eyelashes to natural (real) eyelashes, in particular such compositions which do not contain traditional glues or adhesives or magnets such as those previously used in attaching such false (artificial) products to eyelashes.
[0009] Therefore, one aspect of the present invention is a water-containing eyelash care and / or makeup and / or treatment composition which can be used to adhere or bond false (artificial) eyelashes to natural (real) eyelashes. Summary of the invention

[0014] It is understood that the foregoing general description and the following detailed description are only exemplary and explanatory, and are not restrictive of the invention. DETAILED DESCRIPTION OF THE INVENTION
[0015] In the following description of the invention and the appended claims, it is understood that the terms used have their ordinary and customary meanings in the art, unless otherwise indicated.
[0016] “Approximately,” as used herein, means within 10% of the stated number (e.g., “about 10%” means 9% to 11% and “about 2%” means 1.8% to 2.2%.
[0017] “A” or “an” as used herein means “at least one”.
[0018] “At least one” means one or more and therefore includes the individual components as well as mixtures / combinations.
[0019] In this document, all ranges provided are intended to include each specific range within the given ranges, as well as combinations of sub-ranges therein. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as sub-ranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc.
[0020] “Film-forming”, “film-forming polymer” or “film-forming agent” or “co-film-forming” as used herein means a polymer or resin that leaves a film on the substrate to which it is applied, for example, after a solvent accompanying the film former has evaporated, absorbed into, and / or dissipated on the substrate.
[0021] “Structuring agent” means any wax or fatty acid or fatty alcohol which is solid at room temperature (25°C), having a melting temperature above 30°C and, for example, above 45°C, and a hardness above 0.5 MPa at room temperature.
[0022] A "wax" as used herein is a lipophilic fatty compound that is solid at room temperature (25°C) and reversibly changes from solid to liquid, having a melting temperature greater than 30°C and, for example, greater than 45°C, and a hardness greater than 0.5 MPa at room temperature.
[0023] “True” and “natural” are used interchangeably in this speci fication.
[0024] “Fake” and “artificial” are used interchangeably in this speci fication.
[0025] “Surfactant” and “emulsifier” are used interchangeably in this specification.
[0026] “Substituted” as used herein means comprising at least one substituent. Non-limiting examples of substituents include atoms, such as oxygen atoms and nitrogen 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.

[0027] “Volatile,” as used herein, means having a flash point that is less than about 100°C.
[0028] “Non-volatile,” as used herein, means having a flash point greater than about 100°C.
[0029] “Polymer” as used herein means a compound that consists of at least two monomers.
[0030] “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 to have very small amounts thereof in the compositions of the invention provided that such amounts do not materially affect at least one, preferably most, of the beneficial properties of the conditioning compositions of the invention. Thus, for example, "triethanolamine (TEA)-free" means that an effective (i.e., greater than trace) amount of TEA is omitted from the composition (i.e., about 0% by weight), "substantially TEA-free" means that TEA is present in amounts not exceeding 1% by weight, and "TEA-free" means that TEA is present in amounts not exceeding 0.5% 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, ingredients in adhesives. pressure-sensitive (PSA) agents (compositions of the invention that are “PSA-free,” “substantially PSA-free,” and “PSA-free” have meanings consistent with the discussion in this paragraph), even if they are not specifically discussed for each identified ingredient. The same is true for glues such as, for example, cyanoacrylate-based ingredients (“glue-free,” “substantially glue-free,” and “glue-free,” and “cyanoacrylate-free,” “substantially cyanoacrylate-free,” and “cyanoacrylate-free”) and magnets (“magnet-free,” “substantially magnet-free,” and “magnet-free”)—these phrases are to be understood to have meanings consistent with the discussion in this paragraph. The discussed examples of the use of this language are intended to be exemplary and not limiting.
[0031] “Adhesiveness” as used herein means the quality exhibited by compositions that adhere to an object after application to a substrate. Adhesiveness may be evaluated by any method known in the art for evaluating it, for example, by using a texture analyzer. For example, a sample may be applied to a substrate (e.g., a 1 mil stretch), allowed to dry (e.g., for 1 minute), and contacted with an object such as a conical rubber probe (18.3 mm at the tip, 29 mm in height, and 25.4 mm at the base), after which the force associated with the removal of the probe from the object may be measured and reported as adhesiveness (in g). These measurements may be made less than 5 minutes after the drying period, for example, between 3 and 3 / 2 minutes.Preferably, the compositions of the present invention have tack properties, when determined by this method, greater than 45 g, preferably greater than 50 g, preferably greater than 70 g, preferably greater than 90 g, and preferably greater than 100 g. Thus, the compositions of the present invention preferably have tack properties ranging from about 30 g to about 200 g, preferably from about 50 g to about 150 g, and preferably from about 70 g to about 130 g, including all intermediate ranges and sub-ranges such as, for example, about 45 g to about 110 g, about 50 g to about 110 g, about 70 g to about 120 g, about 90 g to about 115 g, etc.
[0032] “Makeup result”, as used herein, refers to compositions whose color remains the same or substantially the same as at the time of application, as seen with the naked eye, after an extended period of time. The “makeup result” 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 assessed by a test involving the application of a composition to keratinous materials such as eyelashes and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be assessed immediately immediately after application to keratinous materials such as eyelashes and these characteristics can then be re-evaluated and compared after a certain period of time. In addition, these characteristics can be evaluated against other compositions, such as commercially available compositions.
[0033] “Makeup” as used herein means providing decoration (e.g., a color) to the eyelashes.
[0034] “Protect” as used herein means to prevent damage to the eyelashes by providing a protective layer on the eyelashes such as, for example, by applying the compositions of the present invention as a base and / or topcoat composition, and is encompassed within "care".
[0035] 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, the surfactant component of the emulsion composition may "consist essentially of" the identified surfactant(s) or surfactant types discussed below.
[0036] For the purposes of the present invention, the "fundamental and novel property" associated with the compositions, components and methods which "consist essentially of" the identified ingredients or actions is "the attachment of false eyelashes to natural eyelashes."
[0037] Trade names of the materials referred to herein include, but are not limited to, polymers and optional components. The inventors do not intend to be limited by the materials described and referenced by a certain trade name. Equivalent materials (e.g., those obtained from a different source under a different name or catalog (reference) number) to those referenced by a trade name may be substituted and used in the methods described and claimed herein.
[0038] All percentages and ratios are calculated by weight unless otherwise stated. All percentages are calculated based on the total weight of a composition unless otherwise stated. All levels of components or compositions refer to the active level of that component or composition, and exclude impurities, e.g., residual solvents or by-products, which may be present in commercially available sources.

[0140] Unless otherwise indicated, all numbers expressing the quantities of ingredients, the reaction conditions, and so on, used in the specification and claims are to be understood as being modified in all cases by the term "about". Therefore, unless otherwise indicated, the numerical parameters set forth in the following specification and appended claims are approximations which may vary depending on the desired properties sought to be achieved by the present invention.
[0141] Notwithstanding that the numerical ranges and parameters within the general scope of the invention are approximations, the numerical values presented in the specific examples are reported as accurately as possible. However, any numerical value inherently contains certain errors necessarily resulting from the standard deviation observed in their respective measurements. The following examples are intended to illustrate the invention without limiting its scope. Percentages are given on a weight basis. Examples Example I - Sample Formulations
[0142] [Tables 1] Ingredient Preferred Range Specific Range Wax / Polymers 8-45% 8-17% Film-Forming Agent 4-20% 8-18% Emulsifier 4-20% 6-12% Pigment 2.5-20% 5-15% Solvent 20-75% 35-60% Other (Preservative, Fiber, etc.) 0-5% 0-2% Example II - Preparation of the composition
[0143] The compositions may be prepared in a manner customary for mascara products. The compositions of Example I may be prepared by combining all of the oil phase ingredients including the structuring agents in a secondary tank, and then combining the oil phase ingredients with the main aqueous phase including the water-soluble material in the main tank to prepare the composition. Example III - Test Protocols
[0144] Compositions falling within the "preferred ranges" for the ingredients of Example I were prepared. These compositions had the following weight ratios: [Tables 2] Composition Wax / surfactant Wax / film-forming Film-forming / Adhesiveness e surfactant (standard deviation Comp. 1 (t) 2.1 10.8 0.2 35 (10.3) Inv. 1 (sm) 1.5 0.9 1.5 108 (24.1) Inv. 2 (cdo) 0.6 0.60 1.0 92 (33.6) Inv. 3 (fil) 0.99 1.2 0.8 70 (10.3) Inv. 4 (sh) 2.75 6 0.45 57 (17.2)
[0145] Adhesiveness was determined by the protocol described above, performed in triplicate. Specifically, a sample was prepared using a 1 mil downward-drawn bar to create a 1 mil thick film on a stainless steel substrate. After drying for 3 minutes, adhesiveness was measured using a rubber probe on the TA XTPlus Texture Analyzer. A force of 2 grams was applied to the film using the rubber probe. When the rubber probe retracted from the film, the amount of force was measured to determine adhesiveness.
[0146] As can be seen from the above tests, all compositions having a weight ratio between the total amount of structuring agent and the total amount of film-forming agent of less than 10:1 showed an adhesiveness greater than 45 g, in particular greater than 57 g, in contrast to the comparative composition having a weight ratio slightly greater than 10. This test demonstrated the effective nature of the weight ratio of structuring agent to film-forming agent in the compositions tested.
[0147] Similarly, all compositions having a weight ratio of total film-forming agent to total surfactant greater than 0.25:1 exhibited an adhesiveness > 45 g, in particular > 57 g, unlike the comparative composition having a weight ratio slightly lower than 0.25:1. This test demonstrated the effectiveness of the film-forming agent to surfactant weight ratio in the tested compositions.
