Abstract
The invention relates to eyelash and/or eyebrow coating compositions including water, fibers, and at least one latex film-forming agent having a low glass transition temperature (Tg), which can be applied to eyelashes and/or eyebrows (natural or artificial), and which can be used to attach false (artificial) eyelashes and/or eyebrows to natural eyelashes and/or eyebrows, as well as to associated methods.
Description
FIELD OF THE INVENTION

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 the compositions are applied to eyelashes and/or eyebrows, false or artificial eyelashes and/or eyebrows can be adhered to the eyelashes and/or eyebrows by, through or using the applied eyelash and/or eyebrow coating compositions of the present invention by placing the false 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 can be applied to false (artificial) eyelashes and/or eyebrows or natural (real) eyelashes and/or eyebrows, if desired, 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 can be multi-purpose.


DISCUSSION OF THE BACKGROUND

Mascaras typically contain wax which can provide body and volume to the composition. Mascaras can also contain surfactants, particularly when they are in the form of emulsions. However, mascara formulations are typically created to minimize or squelch the full effect of the properties of these ingredients, if present, in an attempt to obtain specific desired properties of the mascara being formulated such as volumization, lengthening, easy removal, etc.


And mascaras can contain fibers as well, typically in low amounts of about 0.1% by weight or less with respect to the total weight of the mascara.


Mascara compositions tend to be of two types, (1) water-resistant, long-wearing mascaras which are anhydrous or (2) removable mascaras (for example, removable with soap and water) which contain water. Generally speaking, water-resistant mascaras are not easily removable, and removable mascaras are not particularly long-wearing.


Regarding application of fake eyelashes to eyelashes, an involved, multistep process is typically used to achieve an acceptable look that blends well with a wearer's natural lashes. The cumbersome process includes a wearer first finding the appropriate style of false eyelashes from myriad of choices, trimming the length of the selection to match their natural eyelash size and/or style, applying adhesive to eyelashes, and then finally attaching and positioning the fake lash onto the eyelid or eyelash.


CA1161330A and U.S. patent application publication 2020/0128897 disclose methods which include separate application of liquid adhesive to eyelashes to moisten them, then application of fiber filaments to the moistened eyelashes, and then applying more liquid adhesive to the eyelashes.


Fake (artificial) eyelashes typically can be applied to natural (real) eyelashes through adhesives (glue) or magnets.


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


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.


U.S. Pat. No. 9,320,920 discloses compositions for making up eyelashes, including false (artificial) eyelashes.


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


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 bind false (artificial) eyelashes and/or eyebrows to natural (real) eyelashes and/or eyebrows.


SUMMARY OF THE INVENTION

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 the compositions are applied to eyelashes and/or eyebrows, false or artificial eyelashes and/or eyebrows can be adhered to the eyelashes and/or eyebrows by, through or using the applied eyelash and/or eyebrow coating compositions of the present invention by placing the false 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 can be applied to false (artificial) eyelashes and/or eyebrows or natural (real) eyelashes and/or eyebrows, if desired, 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 can be multi-purpose. Preferably, the composition (1) comprises at least about 0.25% by weight with respect 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.


The present invention also relates to methods of 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 fake eyelashes and/or eyebrows in an amount sufficient to care for and/or make up the natural or false eyelashes and/or eyebrows.


The present invention also relates to methods of applying fake (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 fake eyelashes and/or eyebrows to the natural eyelashes and/or eyebrows upon which compositions of the present invention have been previously applied, and allowing the compositions of the present invention to dry so that the fake eyelashes and/or eyebrows adhere or bind to the natural eyelashes and/or eyebrows. Preferably, the composition (1) comprises at least about 0.25% by weight with respect 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.


It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the invention.

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


As used herein, all ranges provided are meant to include every specific range within, and combination of subranges between, the given ranges. Thus, a range from 1-5, includes specifically 1, 2, 3, 4 and 5, as well as subranges such as and 2-5, 3-5, 2-3, 2-4, 1-4, etc.


“Film former”, “film-forming polymer” or “film-forming agent” or “co-film former” 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.

“Real” and “natural” are used interchangeably throughout this specification.


“False,” “fake” and “artificial” are used interchangeably throughout this specification.


“Surfactant” and “emulsifier” are used interchangeably throughout this specification.


“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, acyloxyalky groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen containing groups, ester groups, thiol groups, sulphonate groups, thiosulphate groups, siloxane groups, and polysiloxane groups.

“Polymer” as used herein means a compound which is made up of at least two monomers.


“Free of” or “substantially free of” or “devoid of” as it is used herein means that while it is preferred that no amount of the specific component be present in the composition, it is possible to have very small amounts of it in the compositions of the invention provided that these amounts do not materially affect at least one, preferably most, of the advantageous properties of the conditioning compositions of the invention. Thus, for example, “free of triethanolamine (TEA)” means that an effective amount (that is, more than trace amounts) of TEA is omitted from the composition (that is, about 0% by weight), “substantially free of TEA” means that TEA is are present in amounts less than 1% by weight, and “devoid of TEA” 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 for all other ingredients identified throughout the application and in this paragraph such as, for example, cyanoacrylates (“free of cyanoacrylates,” “substantially free of cyanoacrylates,” and “devoid of cyanoacrylates”) and magnets (“free of magnets,” “substantially free of magnets,” and “devoid of magnets”), even if not specifically discussed for each identified ingredient.

Preferably, compositions of the present invention possess tack properties, when determined by this method, of 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. So, 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 ranges and subranges therebetween 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.


“Makeup Result” as used herein, refers to compositions where color remains the same or substantially the same as at the time of application, as viewed by the naked eye, after an extended period of time. “Makeup Result” may be evaluated by evaluating long wear properties by any method known in the art for evaluating such properties. For example, long wear may be evaluated by a test involving the application of a composition to keratin 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 following application to keratin materials such as eyelashes and/or eyebrows and these characteristics may then be re-evaluated and compared after a certain amount of time. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions.


“Making up” as used herein means to provide decoration (for example, color) to the eyelashes and/or eyebrows.


“Protecting” as used herein means to inhibit damage to the eyelashes and/or eyebrows by providing a protective layer on the eyelashes and/or eyebrows such as, for example, through application of the compositions of the present invention and is encompassed within “caring for.”


The compositions and methods of the present invention can 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 can “consist essentially of” identified surfactant(s) or types of surfactants discussed below.


For purposes of the present invention, the “basic and novel property” associated with compositions, components and methods which “consist essentially of” identified ingredients or actions is “attaching fake eyelashes and/or eyebrows to natural eyelashes and/or eyebrows.”


Referred to herein are trade names for materials including, but not limited to polymers and optional components. The inventors herein do not intend to be limited by 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 trade name may be substituted and utilized in the methods described and claimed herein.


All percentages and ratios are calculated by weight unless otherwise indicated. All percentages are calculated based on the total weight of a composition unless otherwise indicated. All component or composition levels are in reference to the active level of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources.


All U.S. patents or patent applications disclosed herein are expressly incorporated by reference in their entirety.

Preferably, the ratio L/D (or aspect ratio) is from 3.5 to 2500, preferably from 10 to 1000, and preferably from 20 to 500, including all ranges and subranges therebetween.


Suitable fibers include fibers which are synthetic or natural, and mineral or organic, in origin. They may be solid or hollow, curved or straight. They may especially have a circular or polygonal (square, hexagonal or octagonal) cross section. Their ends may be blunted and/or smoothed.


Suitable fibers may be those used in the manufacture of textiles, and especially silk fibers, cotton fibers, wool fibers, flax fibers, cellulose fibers, from vegetables or from algae, rayon fibers, polyamide (Nylon®) fibers, viscose fibers, acetate fibers, especially rayon acetate fibers, acrylic polymer fibers, especially polymethyl methacrylate fibers or poly(2-hydroxyethyl methacrylate) fibers, polyolefin fibers and especially polyethylene or polypropylene fibers, polyethylene terephthalate (PET) fibers, polybutylene terephthalate (PBT) fibers, glass fibers, silica fibers, carbon fibers, especially fibers of carbon in graphite form, polytetrafluoroethylene (such as Teflon®) fibers, insoluble collagen fibers, polyester fibers, polyvinyl chloride fibers 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, for instance polyamide/polyester fibers. Furthermore, the fibers may be optionally surface-treated.


Preferably, the fibers are selected from rayon fibers, silk fibers, and mixtures thereof.


Rayon is typically produced by dissolving cellulose, then converting the dissolved cellulose to insoluble fibrous cellulose. Various processes have been developed for production of rayon, such as, for example, the cuprammonium method, the viscose method, and the lyocell process.


Rayon fibers of varying sizes can be made and are commercially-available. Length of rayon fibers is typically provided in units of millimeters (“mm”). Weight/density of the fibers is typically provided in decitex (Dtex) or denier, where Dtex is the weight in grams per 10,000 meters of fiber, and denier is the weight in grams per 9000 meters of fiber. For example, a dtex value of 3.3 corresponds to a denier value of 3.0.


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-0.8 MM and Daitosol 5500), Flockit (0.75 mm/3.3dtex) and Claremont Flock.


Generally speaking, 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 ranges and subranges therebetween such as, for example, about 2 μm to about 50 μm, about 3 μm to about 20 μm, about 3 μm to about 10 μm, about 1 mm to about 1.3 mm, about 0.9 mm to about 1.6 mm, about 1 mm to about 1.5 mm, etc.


The cross section of the fibers may be within a circle of diameter ranging preferably from 2 nm to 500 μm, preferably from 100 nm to 100 μm, and preferably from 1 μm to 50 μm, including all ranges and subranges therebetween.


The weight or yarn 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 ranges and subranges therebetween such as, for example, about 1.5 denier to about 3 denier, about 2 denier to about 3.5 denier, about 4 denier to about 7 denier, etc.


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


Preferably, the fibers is/are present in the compositions of the present invention in amounts of active material (e.g., solid 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 preferably from about 0.5% to about 2%, by weight, based on the total weight of the composition, including all ranges and subranges in between, such as, for example about 0.33% to about 2.25%, about 0.3% to about 5%, about 0.25% to about 2.5%, about 0.4% to about 1.75%, about 0.5% to about 4.3%, etc.


Although not 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 can increase adhesion between the eyelashes and/or eyebrows and the false or artificial eyelashes and/or eyebrows which are applied onto them (after application of compositions of the present invention to the eyelashes and/or eyebrows). It is believed that such increase in adhesion occurs at least in part by the interaction of the fibers and matrix formed by latex film-forming agent(s) having a low glass transition temperature (Tg), resulting in expanded surface area and additional points of contact for the false or artificial eyelashes to adhere on the eyelashes and/or eyebrows (referred to herein as “tendril effect.). Accordingly, fibers, in particular rayon and/or silk fibers, can be added to compositions of the present invention in an “adhesion increasing effective amount” as just described.


Latex Film-Forming Agent Having a Low Glass Transition Temperature (Tg)

According to the present invention, compositions


comprising at least one latex film-forming agent having a low glass transition temperature (Tg) are provided.


“Low glass transition temperature” or “Tg” means a glass transition temperature less than −46° C., preferably −47° C. or lower, preferably −50° C. or lower, and preferably −55° C., including all ranges and subranges therebetween 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.


“Latex” is generally obtained by suspension or emulsion polymerization or copolymerization of monomers according to processes that are well known to those of ordinary skill in the art. Such monomers may be chosen in particular from styrene, butadiene, acrylonitrile, chloroprene, vinyl acetate, urethanes, isoprene, isobutylene, and acrylic or methacrylic acid, maleic acid, crotonic acid or itaconic acid or esters or amides thereof.

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


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.


Vinyl film-forming polymers can result from the polymerization of monomers comprising at least one ethylenic unsaturation and at least one acidic group and/or esters of these acidic monomers and/or amides of these acidic monomers. Monomers comprising at least one acid group which may be used include, for example, α,β-ethylenic 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.


The esters of acidic monomers can be chosen, 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 aryl (meth)acrylates that may be mentioned, examples include benzyl acrylate and phenyl acrylate. The (meth)acrylic acid esters that may be used are, for example, alkyl (meth)acrylates.


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


The vinyl film-forming polymers may also result from the homopolymerization or copolymerization of monomers chosen from vinyl esters and styrene monomers. For example, these monomers may be polymerized with acid monomers and/or esters thereof and/or amides thereof, such as those mentioned above. Examples of vinyl esters that may be mentioned include vinyl acetate, ethylene vinyl acetate, vinyl neodecanoate, vinyl pivalate, vinyl benzoate and vinyl t-butylbenzoate.

The polyesters may be obtained, in a known manner, by polycondensation of dicarboxylic acids with polyols, such as diols.


The dicarboxylic acid may be aliphatic, alicyclic or aromatic. Examples of such acids that may be mentioned include: oxalic acid, malonic acid, dimethylmalonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, 2,2-dimethylglutaric acid, azelaic 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 may be used alone or as a combination of at least two dicarboxylic acid monomers. Among these monomers, phthalic acid, isophthalic acid and terephthalic acid may, for example, be used.


The diol may be chosen from aliphatic, alicyclic and aromatic diols. The diol used is, for example, chosen 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.


The polyesteramides may be obtained in a manner analogous to that of the 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.


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


The aromatic nucleus of the difunctional aromatic monomer also comprising an —SO3M group as described above may be chosen, for example, from benzene, naphthalene, anthracene, biphenyl, oxybiphenyl, sulfonylbiphenyl and methylenebiphenyl nuclei. Among the difunctional aromatic monomers also comprising an —SO3M group, mention may be made, for example, of sulfoisophthalic acid, sulfoterephthalic acid, sulfophthalic acid, 4-sulfonaphthalene-2,7-dicarboxylic acid.


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


The polymer for the film forming particles may also be a liposoluble polymer. Examples of the liposoluble polymer that may be mentioned include copolymers of a vinyl ester (wherein the vinyl group is directly linked to the oxygen atom of the ester group and the vinyl ester comprises a radical chosen from saturated, linear or branched hydrocarbon-based radicals of 1 to 19 carbon atoms, linked to the carbonyl of the ester group) and of at least one other monomer, which may be a vinyl ester (different from the vinyl ester already present), an α-olefin (comprising from 8 to 28 carbon atoms), an alkyl vinyl ether (the alkyl group of which comprises from 2 to 18 carbon atoms) or an allylic or methallylic ester (comprising a radical chosen from saturated, linear or branched hydrocarbon-based radicals of 1 to 19 carbon atoms, linked to the carbonyl of the ester group).


These copolymers may be crosslinked using crosslinking agents that may be either of the vinylic type or of the allylic or methallylic type, such as tetraallyloxyethane, divinylbenzene, divinyl octanedioate, divinyl dodecanedioate and divinyl octadecanedioate.


Examples of these copolymers which may be mentioned include the following copolymers: vinyl acetate/allyl stearate, vinyl acetate/vinyl laurate, vinyl acetate/vinyl stearate, vinyl acetate/octadecene, vinyl acetate/octadecyl vinyl ether, vinyl propionate/allyl laurate, vinyl propionate/vinyl laurate, vinyl stearate/1-octadecene, vinyl acetate/1-dodecene, vinyl stearate/ethyl vinyl ether, vinyl propionate/cetyl vinyl ether, vinyl stearate/allyl acetate, vinyl 2,2-dimethyloctanoate/vinyl laurate, allyl 2,2-dimethylpentanoate/vinyl laurate, vinyl dimethylpropionate/vinyl stearate, allyl dimethylpropionate/vinyl stearate, vinyl propionate/vinyl stearate, crosslinked with 0.2% divinylbenzene, vinyl dimethylpropionate/vinyl laurate, crosslinked with 0.2% divinylbenzene, vinyl acetate/octadecyl vinyl ether, crosslinked with 0.2% tetraallyloxyethane, vinyl acetate/allyl stearate, crosslinked with 0.2% divinylbenzene, vinyl acetate/1-octadecene, crosslinked with 0.2% divinylbenzene, and allyl propionate/allyl stearate, crosslinked with 0.2% divinylbenzene.


Further examples of the liposoluble film-forming polymers include liposoluble copolymers, such as those resulting from the copolymerization of vinyl esters comprising from 9 to 22 carbon atoms or of alkyl acrylates or methacrylates, wherein the alkyl radicals comprise from 10 to 20 carbon atoms.

Example II—Composition Preparation

Compositions corresponding to Example 1A can be prepared by combining all ingredients in a known manner, such as by speedmixing using a Hauschild SpeedMixer® at 2000 RPM for 2-5 min.


Example III—Testing Invention Compositions

Each prepared composition below (invention and comparative) was tested by using a 1 mil drawdown bar to form a film, and repeatedly contacting the film in cycles with a P/0.5 HS probe (5.8 cm in length, with the last 0.5 cm beveled to a hemisphere) during drying. The test speed used for all probe motion (downward to the film, and upward away from the film) was 2 mm/s, with instantaneous contact to the film in each cycle, and approximately a 1.4 s lag in between cycles. For each contact, each film was observed to note any characteristic “tendril effect”; that is, the appearance of a thin filament suspended from the tip of the probe. The duration of “tendril effect” for each inventive and comparative example prepared was recorded, with particular focus on tendril effect reappearance after the film was dry, and duration of the effect.

Observations of the compositions above demonstrated the efficacy of the low Tg film forming agent when combined with the fibers disclosed above with respect to producing a tendril effect. This tendril effect, which could be conceptualized as a fiber-latex matrix interaction, unexpectedly helps facilitate attachment of artificial eye lashes and/or eyebrows through increased points of contact.
