A person skilled in the art will take care to select the optional additional additives and/or the amount thereof such that the advantageous properties of the composition according to the invention are not, or are not substantially, adversely affected by the envisaged addition.These substances may be selected variously by the person skilled in the art in order to prepare a composition which has the desired properties, for example, consistency or texture. These additives may be present in the composition in a proportion from 0% to 99% (such as from 0.01% to 90%) relative to the total weight of the composition and further such as from 0.1 % to 50% (if present).

[0015] Unless otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to understood as being modified in all instances by the term "about". As used herein, "about" or "approximately" shall generally mean within 20 percent, preferably within 10 percent, and more preferably within 5 percent of a given value or range. Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term "about". [0016] As used herein, the expression "at least one" means one or more and thus includes individual components as well as mixtures/combinations.

[0017] As used herein, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will further be understood that the terms "comprising", "including", and variants thereof, when used in this specification, specify the presence of stated features, elements, components, and/or groups thereof.

[0018] As used herein, "keratinous materials" include, but are not limited to, skin, nail, living keratin fibers such as head hair, eyelashes, and eyebrows, and non-living keratin fibers such as swatches, extensions, and false eyelashes. The living and non-living kerating fibers include any mammalian hair, including human hair.

[0019] As used herein, "mascara" and "mascara composition" mean a composition that is intended to be applied to keratinous materials such as eyelashes and/or eyebrows.

[0020] As used herein, "cosmetically acceptable" or "dermatologically acceptable may be utilized and is intended to mean that a composition is suitable for use in contact with human tissues such as keratinous materials and mucous membranes without undue toxicity, incompatibility, instability, and/or allergic response.

[0021] As used herein, "smudging" or "smudging property" is intended to mean that a composition after application leaves a dark ring of composition under the eye of the wearer.

[0022] As used herein, "volume property" or "volumizing" is intended to mean that a composition after application increases the diameter of the individual lash it is a pplied to giving the wearer an appearance of fuller eyelashes.

[0023] The composition herein includes at least one polyvinyl acetate (PVA) solution. PVA is a water-based film forming polymer system, that is fast drying, water-resistant and crystal clear and smudge proof when dry. A non-limiting example of the PVA solution is available commercially as Ultrapure Polymer 2055 available from Ultra Chemical, Red Bank, NJ. The PVA may be present in a range of about 10% to about 20% by weight, relative to the total weight of the composition, including all ranges and subranges there between.

[0024] The composition herein includes at least one polyolprepolymer (SMDI). Polyolprepolymers are high-molecular weight polyalkylene glycol-based polyurethane polymers. Polyolprepolymers are composed of oligomers with a molecular weight from 1,500-18,000. Non-limiting examples of the polyolprepolymer available commercially are polyolprepolymer-2 (PP-2), polyolpreppolymer-14 (PP-14), and polyolprepolymer-15 (PP-15) all available from Barnet Products Co oration, Englewood Cliffs, NJ. The SMDI may be present in a range of about 2% to about 10% by weight, relative to the total weight of the composition, including all ranges and subranges there between.

[0025] The composition herein may include a rosinate (GR). The GR may be present in a range of about 0.5% to about 2% by weight, relative to the total weight of the composition, including all ranges and subranges there between. Non-limiting examples of rosinates used include penthaerythrityl rosinate, a hydrogenated rosinate, a glyceryl rosinate, or the rosinates alone or in combination

[0026] As used herein, "wax" is intended to mean lipophilic fatty compound that is solid at room temperature and atmospheric pressure, and undergoes a reversible solid/liquid change of state and which has a melting point of greater than 30°C, and in some embodiments, greater than about 55°C up to about 120°C. Any waxes used are cosmetically and dermatologically acceptable. The waxes may be used alone or in combination with different kind(s) of waxes. The wax(es) may be present in a range of about 0% to about 10% by weight, relative to the total weight of the composition, including all ranges and subranges there between.

[0027] As used herein, "wear" is intended to mean the amount of smudging and flaking a mascara leaves on the person wearing mascara. Smudging indicates the transfer of color from the eyelash or eyebrow to the skin of the person leaving a dark ring or shadow on the skin. Flaking indicates the mascara coming off the eyelash or eyebrow and appearing as little flakes on the person's skin.

[0028] According to some embodiments the mascara composition may optionally include a wax. The combination of the polyolprepolymer and polyvinyl acetate solution renders inclusion of waxes optional.

[0029] According to some embodiments the composition may further optionally include a surfactant. Any surfactants, including anionic, nonionic, amphoteric, and cationic, surfactants, may be used, as long as the surfactant is cosmetically or dermatologically acceptable. The surfactant may be used singly or in combinations of two or more. If present the amount of surfactant may be from about 0.5% to about 50% by weight, relative to the total weight of the composition, including all ranges and subranges there between.

[0030] According to some embodiments the composition may optionally include at least one colorant. Suitable colorants include, but are not limited to, pigments, dyes such as liposoluble dyes, nacreous pigments, and pearling agents. Typically, when the composition contains colorants, the composition may be used as a mascara composition. Alternatively, when the composition does not contain colorant, it is a clear or transparent composition which can be used as a basecoat (or topcoat) prior to (or after) application of a mascara composition to keratinous materials, or alone as a clear application on the eyelash or eyebrows. However, it is possible that topcoats or basecoats could contain colorants, and/or that a mascara composition could contain little or no colorant.

[0031] Representative liposoluble dyes which may be used are DC dyes of primary colors, beta-carotene, soybean oil, sudan brown, annatto, and quinolone yellow. The liposoluble dyes, if present, can have a concentration of up to 20% by weight of the total weight of the composition, including all ranges and subranges there between.

[0032] Examples of the nacreous pigments that may be selected include white nacreous pigments such as mica coated with titanium or bismuth oxychloride, colored nacreous pigments such as titanium mica with iron oxides, titanium mica with ferric or chromium oxide, titanium mica with organic pigments. If present, the nacreous pigments in the composition can be in a concentration of up to 50% by weight relative to the total weight of the composition, including all ranges and subranges there between.

[0033] Representative pigments which may be used in the composition include, but are not limited to, white, colored, inorganic, organic, polymeric, nonpolymeric, coated and uncoated pigments. A non-exhaustive list of pigments include as example only, metal oxides, lakes, carbon black, manganese violet, ultramarines, and carmine. If present, the pigments may be in the composition in a concentration of up to 50% by weight of the total weight of the composition, including all ranges and subranges there between.

[0034] The composition herein may further include various additives desirably used in cosmetic or dermatological compositions. For example, water, dispersants, polymers, anti-oxidants, pH adjusters, preservatives, neutralizing agents, fragrances, fillers, film formers, co-solvents, plasticizers, cosmetic and dermatological active agents such as emollients, moisturizers, vitamins, UV filters, sunscreens, and mixtures of any of the above. A non-exhaustive listing of such ingredients can be found in the CFTA International Cosmetic /ingredient /dictionary and Handbook, Fourteenth Edition (2012), the contents of which are incorporated by reference here in its entirety.

[0035] One skilled in the art will take care to select the optional additional additives in the concentration to provide the desired properties and performance of the composition. [0036] The composition herein may be in any form suitable for applying on keratinous materials. For example, a mascara composition may be an emulsion (water-in-oil or oil- in-water, multiple emulsions such as water/oil/water and oil/water/oil, or nano-emulsion), a non-emulsified mixture of a water phase and an oil phase, an oil-free composition, or a water-free composition.

[0037] The composition as applied to eyelashes is usually applied using a brush, wand, comb, paper, or fingers. The amount of the composition applied to eyelashes will depend on the user. The mascara composition is applied so as to coat the eyelashes with the composition. The user can apply a single coat or multiple coats of the composition to the eyelash. A coat can be applied, allowed to dry, and another coat applied. This can be repeated until the user obtains the desired effect. The coats can also be applied without drying between coats to obtain the desired effect. The effect may be an increase in volume, length, and/or curl of the eyelash. After application of the composition the eyelashes may appear longer, thicker, and/or curled when compared to the eyelash without the composition applied. The effect may last for 6 -12 hours depending on the activity level of the user.

[0038] The following examples are intended to illustrate the composition performance without limiting the scope as a result. The percentages are given on a weight basis, unless indicated otherwise.

[0039] Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the performance and composition are approximations, the numerical values set forth in the specific examples are reported as precisely as possible within the inherent error and standard deviation found in the instruments used.

[0040] A non-waterproof mascara with film formers was tested to determine the increase in lash thickness after application of the mascara sample using the following procedure.

[0041] A minimum of 15 strands of virgin (undyed) brown hair per sample was used for analysis.

[0042] The base mascara formula was identical for all the samples. The concentration of PVA, SMDI, and GR varied for each formula tested as shown in Table 1.

[0043] Referencing Table 1 , the best performance is seen with the highest number for volume and the lowest number for smudge. A smudge score of ^5.5 is not a viable composition.

[0044] In Table 1 the numbers for Polyvinyl Acetate (PVA), polyolprepolymer (SMDI), and rosinate (GR) are concentration percent. [0045] TABLE
