Description

Title of the invention: EYELASH COATING COMPOSITIONS FOR FALSE EYELASHES FIELD OF THE INVENTION

[0001] The present invention relates to eyelash and / or eyebrow coating compositions comprising water, fibers and at least one latex film-forming agent having a low glass transition temperature (Tg). The eyelash and / or eyebrow coating compositions of the present invention possess sufficient tack and sufficient quick-drying properties such that after application of the compositions to the eyelashes and / or eyebrows, false eyelashes and / or false eyebrows or artificial eyelashes and / or eyebrows can be adhered to the eyelashes and / or eyebrows by means of, through or with the aid of the applied eyelash and / or eyebrow coating compositions of the present invention by placing the false eyelashes and / or false eyebrows or artificial eyelashes and / or eyebrows onto the applied composition and allowing the eyelash and / or eyebrow coating composition to dry.Furthermore, the eyelash and / or eyebrow coating compositions may be applied to false (artificial) eyelashes and / or eyebrows or natural (real) eyelashes and / or eyebrows, as needed, to care for or make up the eyelashes and / or eyebrows and, as such, the eyelash and / or eyebrow coating compositions of the present invention may be versatile. DISCUSSION OF THE CONTEXT

[0002] Mascaras typically contain wax which can provide 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 mitigate the full effect of the properties of these ingredients, if any, in an attempt to achieve specific desired properties of the formulated mascara such as volumizing, lengthening, easy removal, etc.

[0003] And mascaras may also contain fibers, typically in small amounts of about 0.1% by weight or less relative to the total weight of the mascara.

[0004] Mascara compositions tend to be of two types, (1) waterproof, long-lasting mascaras that are anhydrous or (2) removable mascaras (e.g., soap and water removable) that contain water. Generally, waterproof mascaras are not easily removable and removable mascaras are not particularly long-lasting.

[0005] With respect to the application of false eyelashes to eyelashes, a process involving several steps is typically used to achieve an acceptable appearance that blend well with a wearer's natural lashes. The tedious process includes a wearer first finding the appropriate style of false eyelashes from a myriad of choices, trimming the length of the selection to match the size and / or style of their natural lashes, applying adhesive to the lashes, and then finally securing and positioning the false eyelashes on the eyelid or lashes.

[0006] CAI 161330A and US Patent Application Publication 2020 / 0128897 disclose methods that include separately applying liquid adhesive to the eyelashes to moisten them, then applying fiber filaments to the moistened eyelashes, then applying more liquid adhesive to the eyelashes.

[0007] False (artificial) eyelashes can typically be applied to natural (real) eyelashes using adhesives (glue) or magnets.

[0008] For example, US 2016 / 0206031 discloses the use of magnetic materials, and US 2019 / 0261715 discloses magnetic materials in an eyeliner composition.

[0009] As regards 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.

[0010] US 9,320,920 disclose eyelash makeup compositions, including false (artificial) eyelashes.

[0011] There remains a need for improved eyelash and / or eyebrow coating compositions having improved cosmetic properties, which may be useful for attaching false (artificial) eyelashes and / or eyebrows to natural (real) eyelashes and / or eyebrows.

[0012] Accordingly, one aspect of the present invention is a water-containing care and / or makeup and / or treatment composition for eyelashes and / or eyebrows which can be used to adhere or bond false (artificial) eyelashes and / or eyebrows to natural (real) eyelashes and / or eyebrows. Summary of the invention

[0013] The present invention relates to eyelash and / or eyebrow coating compositions comprising water, fibers and at least one latex film-forming agent having a low glass transition temperature (Tg). The eyelash and / or eyebrow coating compositions of the present invention possess sufficient tack and sufficient quick-drying properties such that after application of the compositions to the eyelashes and / or eyebrows, false eyelashes and / or false eyebrows or artificial eyelashes and / or eyebrows can be adhered to the eyelashes and / or eyebrows by means of, through or with the aid of the applied eyelash and / or eyebrow coating compositions of the present invention by placing the false eyelashes and / or false eyebrows or artificial eyelashes and / or eyebrows on the applied composition and allowing the eyelash and / or eyebrow coating composition to dry. Further, the eyelash and / or eyebrow coating compositions may be applied to false (artificial) eyelashes and / or eyebrows or natural (real) eyelashes and / or eyebrows, as needed, to care for or make up the eyelashes and / or eyebrows and, as such, the eyelash and / or eyebrow coating compositions of the present invention may be versatile. Preferably, the composition (1) comprises at least about 0.25% by weight relative to the total weight of the composition of fibers; and / or (2) further comprises at least one coloring agent, at least one wax, and / or at least one surfactant.

[0014] The present invention also relates to methods for caring for and / or making up real (natural) eyelashes and / or eyebrows, or false (artificial) eyelashes and / or eyebrows, by applying compositions of the present invention to natural or false eyelashes and / or eyebrows in a quantity sufficient to care for and / or make up the natural or false eyelashes and / or eyebrows.

[0015] The present invention also relates to methods of applying false (artificial) eyelashes and / or eyebrows to real (natural) eyelashes and / or eyebrows comprising applying compositions of the present invention to natural eyelashes and / or eyebrows, applying false eyelashes and / or eyebrows to the natural eyelashes and / or eyebrows to which compositions of the present invention have previously been applied, and allowing the compositions of the present invention to dry such that the false eyelashes and / or eyebrows adhere or bond to the natural eyelashes and / or eyebrows. Preferably, the composition (1) comprises at least about 0.25% by weight relative to the total weight of the composition of fibers; and / or (2) further comprises at least one coloring agent, at least one wax, and / or at least one surfactant.

[0016] It should be understood that both the foregoing general description and the following detailed description are provided by way of example and explanation only, and do not limit the invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] In the following description of the invention 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.

[0018] “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%.

[0019] “A” or “an” as used herein means “at least one”

[0020] “At least one” means one or more and thus includes components in individual as well as mixtures / combinations.

[0021] As used herein, all proposed ranges are intended to include each range specific within the given ranges, and all combinations of subranges in between. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as the subranges 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc.

[0022] “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-forming material has evaporated, been absorbed into, and / or dissipated on the substrate.

[0023] “Wax” as used herein means a lipophilic fatty compound that is solid at tem room temperature (25°C) and changes from the solid state to the liquid state reversibly, having a melting temperature above 30°C and, for example, above 45°C and a hardness above 0.5 MPa at room temperature.

[0024] “True” and “natural” are used interchangeably throughout the present memory.

[0025] “Fake” and “artificial” are used interchangeably throughout the present memory.

[0026] “Surfactant” and “emulsifier” are used interchangeably throughout throughout this memorandum.

[0027] “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. The substituent(s) may be further substituted.

[0028] "Volatile" as used herein means having a flash point less than about 100°C.

[0029] “Non-volatile,” as used herein, means having a flash point greater than about 100°C. “Polymer” as used herein means a compound that consists of at least two monomers.

[0030] “Polymer” as used herein means a compound that is made up of at least two monomers.

[0031] “Exempt” or “substantially free” or “devoid of” as used herein means that although it is preferable that no amount of the specific component is present in the composition, it is possible for there to be 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 advantageous properties of the revitalizing compositions of the invention. Thus, for example, "free from triethanolamine (TEA)” means that an effective amount (i.e., greater than trace amounts) of TEA is omitted from the composition (i.e., about 0% by weight), “substantially free of TEA” means that TEA is present in amounts less than 1% by weight, and “TEA-free” means that TEA is present in amounts less than 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, cyanoacrylates (“cyanoacrylate-free,” “substantially cyanoacrylate-free,” and “cyanoacrylate-free”) and magnets (“magnet-free,” “substantially magnet-free,” and “magnet-free,” even if not specifically discussed for each identified ingredient.As used herein, these expressions are to be understood to have meanings consistent with the discussion within this paragraph. As noted, the examples discussed of the use of such language are intended to be exemplary, not limiting.

[0032] “Tackiness” as used herein refers to the quality demonstrated by the com positions that adhere to an object after application to a substrate. Tackiness may be assessed by any method known in the art for assessing it, such as the use of a texture analyzer. For example, one may apply a sample to a substrate (e.g., a 1 mil swab), allow it to dry (e.g., for 1 minute), and contact it with an object such as a cylindrical acrylic probe (4 cm height, 1.2 cm base diameter), after which the force associated with removing the probe from the object may be measured and reported as tackiness (g). These measurements may be made less than 5 minutes after the drying period, e.g., between 3 and 3 minutes and ^2.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, from about 45 g to about 110 g, from about 50 g to about 110 g, from about 70 g to about 120 g, from about 90 g to about 115 g, etc.

[0033] “Makeup result” as used herein refers to compositions where the 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 evaluated by a test involving the application of a composition to keratinous materials such as eyelashes and / or eyebrows and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately after application to keratinous materials such as eyelashes and / or eyebrows and these characteristics may then be re-evaluated and compared after a period of time. In addition, these characteristics may be evaluated relative to other compositions, such as commercially available compositions.

[0034] “Make up” as used herein means to provide decoration (e.g., color) to the eyelashes and / or eyebrows.

[0035] “Protect” as used herein means inhibit damage to the cilia and / or eyebrows by providing a protective layer on the eyelashes and / or eyebrows such as, for example, by applying the compositions of the present invention and is encompassed within "caring for".

[0036] 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" one or more identified surfactants or types of surfactants discussed below.

[0037] For the purposes of the present invention, the “fundamental and novel property” associated with the compositions, components and methods which “consist essentially of” identified ingredients or actions is “the attachment of false eyelashes and / or false eyebrows to natural eyelashes and / or eyebrows”.

[0038] Reference is made herein to trade names of materials including, but not limited to, polymers and optional components. The inventors do not intend herein to be limited to the materials described and referenced by a certain trade name. 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.

[0039] 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.

[0040] All US patents or patent applications disclosed herein are expressly incorporated by reference in their entirety. Water

[0041] According to the present invention, compositions comprising water are provided. The compositions of the present invention are not anhydrous. Preferably, the compositions of the present invention comprise from about 20% to about 75% water, preferably from about 25% to about 70% water, preferably from about 30% to about 60% water, and most preferably from about 30% to about 55% water by weight based on the total weight of the composition, including all intermediate ranges and sub-ranges, such as, for example, from about 30% to about 70%, from about 25% to about 60%, from about 40% to about 55%, etc. Preferably, the compositions of the present invention are in the form of an emulsion, with a simple emulsion such as an oil-in-water (O / W) or a wax-in-water being the most preferred form. Fibers

[0042] According to the present invention, compositions comprising fibers are provided.

[0043] “Fiber” as used herein means a linear object of length L and diameter D such that L is greater than D, preferably much greater than D, where D is the diameter of the circle in which the cross-section of the fiber is inscribed. Preferably, the L / D ratio (or aspect ratio) is from 3.5 to 2500, preferably from 10 to 1000, and preferably from 20 to 500, including all intermediate ranges and sub-ranges.

[0044] Suitable fibers include fibers that are of synthetic or natural, and mineral or organic origin. They may be solid or hollow, curved or straight. In particular, they may have a circular or polygonal (square, hexagonal or octagonal) section. Their ends may be blunt and / or smoothed.

[0045] Suitable fibers may be those used in the manufacture of textiles, and in particular silk fibers, cotton fibers, wool fibers, flax fibers, cellulose fibers, from vegetables or algae, rayon fibers, polyamide fibers (Nylon®), viscose fibers, acetate fibers, in particular acetate rayon fibers, acrylic polymer fibers, in particular polymethyl methacrylate or poly(2-hydroxyethyl)methacrylate fibers, polyolefin fibers and in particular polyethylene or polypropylene fibers, polyethylene terephthalate (PET) fibers, polyethylene terephthalate (PBT) fibers, glass fibers, silica fibers, carbon fibers, in particular carbon fibers in the form of graphite, polytetrafluoroethylene fibers (such as Teflon®), insoluble collagen fibers, polyester fibers,polyvinyl chloride or polyvinylidene chloride fibers, polyvinyl alcohol fibers, polyacrylonitrile fibers, chitosan fibers, polyurethane fibers, polyethylene phthalate fibers, or fibers formed from a mixture of polymers, such as those mentioned above, e.g. polyamide / polyester fibers. In addition, the fibers can optionally be surface treated.

[0046] Preferably, the fibers are chosen from rayon fibers, silk fibers, and mixtures thereof.

[0047] Rayon is generally produced by dissolving cellulose and then converting the dissolved cellulose into insoluble fibrous cellulose. Various processes have been developed for the production of rayon, such as, for example, the cu-prammonium method, the viscose method, and the lyocell process.

[0048] Rayon fibers of varying sizes can be manufactured and are commercially available. Rayon fiber length is typically stated in millimeters (“mm”). Fiber mass / density is typically provided in decitex (Dtex) or denier, where Dtex is the mass in grams per 10,000 meters of fiber and denier is the mass in grams per 9000 meters of fiber. For example, a dtex value of 3.3 corresponds to a denier value of 3.0.

[0049] Rayon fibers are generally commercially available such as, for example, from Daito Kasei Kogyo, Moley Coating Solutions (1.7 Dtex, 0.3-0.6 mm; 3.3 Dtex, 0.3-1 mm), Kobo Products (e.g., Rayon Fiber 3.3T-0.8MM and Daitosol 5500), Flockit (0.75 mm / 3.3 dtex) and Claremont Flock.

[0050] Generally, the fibers of the present invention preferably have a length ranging from 1 μm to 10 mm, preferably from 0.1 mm to 5 mm, preferably from 0.3 mm to 3 mm, preferably from 0.5 mm to 2.0 mm, preferably from about 0.75 mm to about 1.75 mm, preferably from about 0.8 mm to about 1.6 mm, preferably from about 0.9 mm to about 1.5 mm, and preferably from about 1 mm to about 1.5 mm, including all intermediate ranges and sub-ranges such as, for example, from about 2 μm to about 50 μm, from about 3 μm to about 20 μm, from about 3 μm to about 10 μm, from about 1 mm to about 1.3 mm, from about 0.9 mm to about 1.6 mm, from about 1 mm to about 1.5 mm, etc.

[0051] The cross-section of the fibers may be comprised within a circle with a diameter preferably ranging from 2 nm to 500 pm, preferably from 100 nm to 100 pm, and preferably from 1 pm to 50 pm, including all intermediate ranges and sub-ranges.

[0052] The mass or count of the fibers may preferably range from 0.1 to 10 denier, preferably from 1 to 7 denier, preferably from about 1.5 denier to about 5 denier and preferably from about 2 denier to about 4 denier, including all intermediate ranges and sub-ranges such as, for example, from about 1.5 denier to about 3 denier, from about 2 denier to about 3.5 denier, from about 4 denier to about 7 denier, etc.

[0053] It is to be understood that the present disclosure contemplates fibers having length, cross-sectional area and weight characteristics resulting from the combination of properties discussed above, in particular rayon and / or silk. For example, the disclosure particularly contemplates rayon and / or silk fibers having a length of about 1 mm to about 1.3 mm and a mass of about 2 denier to about 3.5 denier, with a cross-section as discussed above. Similarly, the disclosure particularly contemplates rayon and / or silk fibers having a length of about 0.9 mm to about 1.6 mm and a mass of about 1.5 denier to about 3 denier, with a cross-section as discussed above.

[0054] Preferably, the fibers are present in the compositions of the present invention in amounts of active material (e.g., solids content) generally ranging from about 0.25% to about 5%, preferably from about 0.3% to about 4%, preferably from about 0.4% to about 3%, and most preferably from about 0.5% to about 2%, by weight, based on the total weight of the composition, including all intermediate ranges and sub-ranges, such as, for example, from about 0.33% to about 2.25%, from about 0.3% to about 5%, from about 0.25% to about 2.5%, from about 0.4% to about 1.75%, from about 0.5% to about 4.3%, etc.

[0055] Without wishing to be bound by any particular theory, it is believed that when fibers are added to compositions of the present invention in combination with latex film-forming agent(s) having a low glass transition temperature (Tg) discussed herein, the fibers and latex(es) in a single composition may increase adhesion between eyelashes and / or eyebrows and the false eyelashes and / or eyebrows or artificial false eyelashes and / or eyebrows applied thereto (after application of the compositions of the present invention to the eyelashes and / or eyebrows).This increase in adhesion is believed to occur at least in part through the interaction of the fibers and the matrix formed by the latex film-forming agent(s) having a low glass transition temperature (Tg), resulting in an enlarged surface area and additional contact points for the false or artificial eyelashes to adhere to the eyelashes and / or eyebrows (referred to herein as the "twist effect"). Accordingly, fibers, particularly rayon and / or silk fibers, may be added to the compositions of the present invention in an "effective adhesion-increasing amount" as just described.

[0056] Latex film-forming agent having a low temperature glass transition (tg)

[0057] According to the present invention, compositions comprising at least one latex film-forming agent having a low glass transition temperature (Tg) are provided.

[0058] “Low glass transition temperature” or “Tg” means a temperature of glass transition below -46°C, preferably -47°C or below, preferably -50°C or below, and preferably -55°C, including all intermediate ranges and sub-ranges such as, for example, -47°C to -100°C, -47°C to -75°C, -47°C to -67°C, -50°C to -100°C, -50°C to -75°C, -50°C to -70°C, etc.

[0059] The “latex” is generally obtained by suspension or emulsion polymerization or copolymerization of monomers according to processes well known to those skilled in the art. Such monomers may be chosen in particular from styrene, butadiene, acrylonitrile, chloroprene, vinyl acetate, methanes, isoprene, isobutylene and acrylic or methacrylic acid, maleic acid, crotonic acid or itaconic acid or their esters or amides.

[0060] Suitable latexes include particles having molecular weights greater than 100,000 Da weight average molecular weight, preferably greater than 120,000 Da, preferably greater than 135,000 Da, and preferably greater than 150,000 Da, including all intermediate ranges and sub-ranges.

[0061] Suitable polymers for film-forming particles that may be used in the compositions of the present invention include, but are not limited to, synthetic, free radical, or polycondensate polymers, naturally occurring polymers, and mixtures thereof.

[0062] Preferably, the polymers for the film-forming particles may be chosen from vinyl (co)polymers, (meth)acrylic (co)polymers, methane (co)polymers, and mixtures thereof. Advantageously, the polymer for the film-forming particles is chosen from a styrene-(meth)acrylic and (meth)acrylic copolymer, a vinyl acetate and (meth)acrylic copolymer, and mixtures thereof.

[0063] The polymers for the film-forming particles of the free radical type may be chosen, for example, from vinyl polymers or copolymers, such as acrylic polymers.

[0064] The vinyl film-forming polymers may result from the polymerization of monomers comprising at least one ethylenic unsaturation and at least one acid group and / or esters of these acid monomers and / or amides of these acid monomers. Monomers comprising at least one acid group that may be used include, for example, α,[3-ethylenically unsaturated carboxylic acids such as acrylic acid, methacrylic acid, crotonic acid, maleic acid or itaconic acid. (Meth)acrylic acid and crotonic acid are, for example, used. Preferably, (meth)acrylic acid is used.

[0065] The acid monomer esters may be selected, for example, from (meth)acrylic acid esters (also known as (meth)acrylates), such as (meth)acrylates of an alkyl, for example, a C1-C30 alkyl, such as a C1-C20 alkyl, (meth)acrylates of an aryl, such as a C6-C10 aryl, and (meth)acrylates of a hydroxyalkyl, such as a C2-C6 hydroxyalkyl. Among the alkyl (meth)acrylates that may be cited, examples include methyl methacrylate, ethyl methacrylate, butyl methacrylate, methacrylate isobutyl methacrylate, 2-ethylhexyl methacrylate, lauryl methacrylate and cyclohexyl methacrylate. Examples of hydroxyalkyl (meth)acrylates that may be cited include hydroxyethyl acrylate, 2-hydroxypropyl acrylate, hydroxyethyl methacrylate and 2-hydroxypropyl methacrylate. Examples of aryl (meth)acrylates that may be cited include benzyl acrylate and phenyl acrylate. Examples of (meth)acrylic acid esters that may be used are, for example, alkyl (meth)acrylates.

[0066] The alkyl group of the esters may be substituted. For example, the alkyl group of the esters may be fluorinated or perfluorinated, i.e., some or all of the hydrogen atoms of the alkyl group are substituted with fluorine atoms. Furthermore, examples of amides of the acid monomers that may be cited include (meth)acrylamides, such as N-alkyl(meth)acrylamides, for example, of C2-C12 alkyl. Among the N-alkyl(meth)acrylamides that may be cited, examples include N-ethylacrylamide, Nt-butylacrylamide, Nt-octylacrylamide and N-undecylacrylamide.

[0067] Vinyl film-forming polymers can also result from homopolymerization or copolymerization of monomers selected from vinyl esters and styrene monomers. For example, these monomers may be polymerized with acid monomers and / or their esters and / or their amides, such as those cited above. Examples of vinyl esters that may be cited include vinyl acetate, ethylene vinyl acetate, vinyl neodecanoate, vinyl pivalate, vinyl benzoate and vinyl t-butylbenzoate. Styrene monomers that may be cited include styrene and α-methylstyrene.

[0068] Among the film-forming polycondensates that may be cited, examples include polyurethanes, polyesters, polyesteramides, polyamides, epoxy ester resins and polyureas, and modifications or derivatives of any of these.

[0069] The polyurethanes may be chosen from anionic, cationic, non-ionic or amphoteric polyurethanes, polyurethane-acrylics, polyurethane-polyvinylpyrrolidones, polyester-polyurethanes, polyether-polyurethanes, polyureas and polyurea-polyurethanes, and mixtures thereof.

[0070] Polyesters can be obtained, in a known manner, by polycondensation of dicarboxylic acids with polyols, such as diols.

[0071] The dicarboxylic acid may be aliphatic, alicyclic or aromatic. Examples of such acids that may be cited include: oxalic acid, malonic acid, dimethylmalonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, 2,2-dimethylglutaric acid, azelaic acid, acid suberic acid, sebacic acid, fumaric acid, maleic acid, itaconic acid, phthalic acid, dodecanedioic acid, 1,3-cyclohexanedicarboxylic acid, 1,4-cyclohexanedicarboxylic acid, isophthalic acid, terephthalic acid, 2,5-norbornanedicarboxylic acid, diglycolic acid, thiodipropionic acid, 2,5-naphthalenedicarboxylic acid and 2,6-naphthalenedicarboxylic acid. These dicarboxylic acid monomers can be used alone or in combination of two or more dicarboxylic acid monomers. Among these monomers, phthalic acid, isophthalic acid and terephthalic acid can, for example, be used.

[0072] The diol may be selected from aliphatic, alicyclic and aromatic diols. The diol used is, for example, selected from ethylene glycol, diethylene glycol, triethylene glycol, 1,3-propanediol, cyclohexanedimethanol and 4-butanediol. Other polyols that may be used include glycerol, pentaerythritol, sorbitol and trimethylolpropane.

[0073] Polyesteramides may be obtained in a manner analogous to that for obtaining polyesters, by polycondensation of diacids with diamines or amino alcohols. Diamines that may be used include, for example, ethylenediamine, hexamethylenediamine and meta- or para-phenylenediamine. An amino alcohol that may be used is, for example, monoethanolamine.

[0074] The polyester may also comprise at least one monomer carrying at least one -SO3M group, in which M is chosen from a hydrogen atom, an ammonium ion NH4+ and a metal ion such as a Na+, Li+, K+, Mg2+, Ca2+, Cu2+, Fe2+ or Fe3+ ion. A difunctional aromatic monomer comprising such a -SO3M group may, for example, be used.

[0075] The aromatic nucleus of the difunctional aromatic monomer also comprising a —SO3M group as described above may be selected, for example, from benzene, naphthalene, anthracene, biphenyl, oxybiphenyl, sulfonyl-biphenyl and methylenebiphenyl nuclei. Among the difunctional aromatic monomers also comprising a —SO3M group, mention may be made, for example, of sulfoi-sophthalic acid, sulfoterephthalic acid, sulfophthalic acid, 4-sulfonaphthalene-2,7-dicarboxylic acid.

[0076] The copolymers used are, for example, those based on isophthalate / sulfoisophthalate, such as the copolymers obtained by condensation of diethylene glycol, cyclohexanedimethanol, isophthalic acid and sulfisophthalic acid.

[0077] The polymer for the film-forming particles may also be a liposoluble polymer.

[0132] A person skilled in the art will take care to choose the optional additional additives and / or their quantity so that the advantageous properties of the composition according to the invention are not, or not substantially, compromised by the envisaged addition.

[0133] These substances can be chosen in various ways by those skilled in the art in order to prepare a composition which has the desired properties, for example, consistency or texture.

[0134] These additives may be present in the composition in a proportion of 0% to 99% (such as 0.01% to 90%) relative to the total weight of the composition and in further such as from 0.1% to 50% by weight (as applicable), including all intermediate ranges and sub-ranges.

[0135] It goes without saying that the composition of the invention must be cosmetically or dermatologically acceptable, namely that it must contain a physiologically acceptable non-toxic medium and must be able to be applied to the eyelashes and / or eyebrows of human beings.

[0136] According to preferred embodiments of the present invention, methods of caring for and / or making up eyelashes and / or eyebrows (artificial or natural) by applying compositions of the present invention to the eyelashes and / or eyebrows in an amount sufficient to care for and / or make up the eyelashes and / or eyebrows are provided. According to some embodiments, "making up" the keratinous material includes applying a composition comprising at least one coloring agent to the eyelashes and / or eyebrows in an amount sufficient to provide color to the eyelashes and / or eyebrows.

[0137] In accordance with the preceding preferred embodiments, the compositions of the present invention are applied topically to the desired area of ​​the eyelashes and / or eyebrows in an amount sufficient to condition and / or condition the eyelashes and / or eyebrows. The compositions may be applied to the desired area as needed, preferably once or twice daily, more preferably once daily, and then preferably allowed to dry before subjecting them to contact such as with clothing or other objects (e.g., a topcoat). Preferably, the composition is allowed to dry for about 1 minute or less, more preferably for about 45 seconds or less. The composition is preferably applied to the desired area that is dry or has been dried prior to application or to which a basecoat has been applied.

[0138] According to preferred embodiments of the present invention, methods for applying (artificial) false eyelashes and / or eyebrows to real (natural) eyelashes and / or eyebrows comprising applying compositions of the present invention to natural eyelashes and / or eyebrows, applying false eyelashes and / or eyebrows to the natural eyelashes and / or eyebrows to which compositions of the present invention have previously been applied, and allowing the compositions of the present invention to dry so that the false eyelashes and / or eyebrows attach to the natural eyelashes and / or eyebrows are provided. Preferably, the composition (1) comprises at least about 0.25% by weight relative to the total weight of the composition of fibers; and / or (2) further comprises at least one coloring agent, at least one wax, and / or at least one surfactant.

[0139] In accordance with the preceding preferred embodiments, the compositions of the present invention are applied topically to the desired area of ​​the eyelashes and / or eyebrows in an amount sufficient to attach false eyelashes and / or false (artificial) eyebrows to the natural eyelashes and / or eyebrows. The compositions may be applied to the desired area as required, preferably once or twice before attaching the artificial eyelashes and / or eyebrows, and then allowed to dry after contact of the applied composition with the artificial eyelashes and / or eyebrows for attachment to the eyelashes and / or eyebrows. Preferably, the artificial eyelashes and / or eyebrows are brought into contact with the applied composition less than 1 minute after application of the composition to the natural eyelashes and / or eyebrows, more preferably less than 45 seconds after application.

[0140] Typical removal methods and solutions may be used to remove the artificial eyelashes and / or eyebrows from the natural eyelashes and / or eyebrows, if desired.

[0141] Unless otherwise indicated, all numbers expressing amounts of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term "about." Accordingly, 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.

[0142] Although the numerical ranges and parameters presenting the broad 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 found in their respective measurements. The following examples are intended to illustrate the invention without limiting its scope accordingly. Percentages are given on a weight basis. EXAMPLES Example IA - Sample Glue Formulations

[0143] [Tables 1] Ingredient Preferred Range Specific Range Low Tg Latex (active ingredient) 40-67% 50-55% Water QS QS Fiber 0.25-5% 0.25-2.5% Other (preservative, filler, etc.) 0-5% 0-2.5% Example IB - Sample Mascara Formulations

[0144] [Tables2] Ingredient Preferred Range Specific Range Low Tg Latex (Active Ingredient) 10-30% 10-20% Coloring Agent 3-20% 5-10% Wax 3-20% 5-15% Surfactant 3-20% 5-15% Water QS QS Fiber 0.25-5% 0.25-2.5% Other (Preservative, Filler, etc.) 0-10% 0-10% Example II - Preparation of the composition

[0145] The compositions corresponding to Example IA may be prepared by combining all the ingredients in a known manner, such as by rapid mixing using a Hauschild SpeedMixer® at 2000 rpm for 2 to 5 min. Example III - Testing of inventive compositions

[0146] Each composition prepared below (inventive and comparative) was tested using a 1 mil pinch bar to form a film, and repeatedly contacting the film in cycles with a P / 0.5 HS probe (5.8 cm long, the last 0.5 cm beveled into a hemisphere) during drying. The test speed used for all probe movements (down to the film and up away from the film) was 2 mm / s, with instantaneous contact with the film at each cycle and a delay of approximately 1.4 s between cycles. For each contact, each film was observed to note any characteristic "twirl effect," i.e., the appearance of a thin filament suspended from the probe tip.The duration of the "twirl effect" for each inventive and comparative example prepared was recorded, with particular emphasis on the reappearance of the twist effect after the film dried, and the duration of the effect. Essay A - Inventive Compositions

[0147] [Tables3] Ingredients Exl Ex 2 Ex 3 Ex 4 Acrylates / ethylhexyl acrylate copolymer (Tg = -66 °C) 55 55 55 55 Water QS QS QS QS Linear rayon fibers (1 mm) 0.3 Linear rayon fibers (1.3 mm) 0.3 Linear rayon fibers (3 mm) 1 Linear silk fibers 0.3 Twist appearance Yes - appears during drying (60 s) and lasts after the film is completely dry Yes - appears during drying (70 s) and lasts after the film is completely dry Yes - appears during drying (45 s) and lasts after the film is completely dry Yes - appears during drying (70 s) and lasts after the film is completely dry

[0148] The above tests demonstrated that the inventive compositions resulted in persistent twisting using different fibers of different lengths.

[0149] Test B - Test of inventive and comparative compositions

[0150] [Tables4] Ingredients Ext (inventive above) Ex 5 (inventive) Ex 6 (inventive) Cl (comparative) Acrylates / ethylhexyl acrylate copolymer (Tg = -66 °C) 55 55 52 55 Water QS QS QS QS Linear radius (1 mm) 0.3 1 5 0.03 Appearance of curl Yes - appears during drying (60 s) and lasts after the film is completely dry Yes - appears during drying (60 s) and lasts after the film is completely dry Yes - appears during drying (80 s) and lasts after the film is completely dry No - Floating, appears only during the film drying (70 s) and disappears once the film is dry

[0151] The persistence of the spin effect has thus been demonstrated at concentrations ranging from 0.3% to 5%. Test C - Comparative Compositions vs. Example 1

[0152] Table 51

[0153] Table 3. Comparative examples concerning the morphology of the charge and the absence of charge Ingredients Exl (inventive above) C2 (comparative) C3 (comparative) C4 (comparative) Acrylates copolymer / ethylhexyl acrylate (Tg = -66 °C) 55 55 55 55 Water QS QS QS QS Spherical Nylon Fiber 12 0.3 Spherical Cellulose 0.3 Linear Rayon (1 mm) 0.3 Curl Appearance Yes - appears during drying (60 s) and lasts after the film is completely dry No — Floating, appears only during film drying (70 s) and disappears after the film is dry No — Floating, appears only during film drying (70 s) and disappears after the film is dry No — Floating, appears only during film drying (70 s) and disappears after the film is dry

[0154] The persistence of the twist effect has thus been demonstrated for linear fibers.

[0155] Test D - Comparative compositions with polymers before a higher Tg

[0156] [Tableauxô] Ingredients C5 (Test 12) C6 (Test 13) Acrylates copolymer 42.75 47.5 Water QS QS Rayon (1 mm) 5 5 Tg (°C) 13.6 -14 Appearance of twisting No No

[0157] The absence of the twist effect has thus been demonstrated for compositions having a polymer with a higher Tg.

[0158] Test E - Comparative compositions with polymers having a higher Tg

[0159] [Table 7]

[0160] Table 5. Inventive and comparative examples relating to low Tg Acrylate copolymers Ingredients Ex 6 C7 C8 (Test 6) (Test 15) (Test 16) Acrylates / ethylhexyl acrylate copolymer 52.5 Polyurethane-35 39 Acrylates copolymer 48.4 Water QS QS QS Rayon (1 mm) 5 5 5 Tg (°C) -66 -46 -49 Curling Yes - appears during drying (80 s) and lasts after the film has completely dried No Yes - appears only after the film has completely dried (120 s) and lasts thereafter

[0161] The observations of the above compositions demonstrated the effectiveness of the low Tg film-forming agent when combined with the above-disclosed fibers in producing a twisting effect. This twisting effect, which could be conceptualized as a fiber-latex matrix interaction, unexpectedly contributes to facilitating the attachment of artificial eyelashes and / or eyebrows by increasing the contact points.
