DESCRIPTION

[0010] Embodiments of the present invention are discussed in detail below. In describing embodiments, specific terminology is employed for the sake of clarity. However, the invention is not Intended to be limited to the specific terminology so selected. While specific exemplary embodiments are discussed, It should be understood that this is done for illustration purposes only, A person skilled in the relevant art will recognize that other components and configurations can be used without parting from the spirit and scope of the invention. While a number of embodiments and features are described herein, it is to be understood that the various features of the Invention and aspects of embodiments, even if described separately, may be combined unless mutually exclusive or contrary to the specific description. All references cited herein are incorporated by reference as if each had been individually incorporated.

[0011] As used In the present disclosure the compositions may be applied to a natural nail or a synthetic nail. The natural nail is the natural keratinous material known as fingernails and toenails. Synthetic nails are comprised of chemically reactive monomers, and/or oligomers, in combination with reactive or non-reactive polymers to create systems which are typically 100% solids and do not require non-reactive solvents, Upon pre-mixlng and subsequent application to the natural nail, or application and exposure to UV radiation, a chemical reaction ensues resulting in the formation of a long lasting, highly durable cross-linked nail coating that Is difficult to remove. Artificial nails may possess greatly enhanced adhesion, durability, as well as scratch and solvent resistance when compared to nail polishes.

[0012] Nail coatings have traditionally boon be classified into two categories; nail polishes; also known as lacquers, varnish or enamels and artificial nails; also known as gels or acrylics. Nail polishes typically comprise various solid components which are dissolved and/of suspended in non- reactive solvents. Upon application and drying, the solids deposit on the nail surface as a clear, translucent or colored film.

[0013] Contemporary nail coatings are enhanced nail coatings contain higher performance polymers, higher levels of pigments, alternative pigments (e.g. blues and blacks}., glitters, and photo-reactive nail coatings to provide a durable scratch resistant nail coating with improved adhesion.

[0014] As used herein, the expression "at least one" means one or more and thus includes Individual components as well as mixtures and combinations.

[0015] AS' used herein, the expression "about" shall generally mean 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 andfor reaction conditions are to be understood as being modified in all instances by the term "about".

10016] The cosmetic compositions and methods of the present disclosure consist of, or consist essentially of the elements and limitations described herein, as well as any additional or optional ingredients, components, or limitations otherwise useful as found in persona! care compositions intended for application to naif coatings. 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 skitled 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 :99¾ (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). Non-llmitlng examples of additives include colors and fragrances.

[0017] Suitable colors are created by including in the composition, but are not limited to, pigments and dyes.

[0018] According to the present disclosure .layers of composition describe the application of nail coatings. A composition is painted on the nail to provide a cosmetic coloring or a healing or strengthening of the nail. Application is done by painting a composition on the nail, According to an aspect, the nail coating composition fs applied, and at least partially dried as three, distinct layers. According to an aspect, application of any one Of the layers may be omitted. According to an aspect, application of any two of the layers may be omitted. According to an aspect, only a formulation for a color layer comprises colorant agents. According to an aspect, a formulation for any of the layers may comprise colorant

[0019] The organic solvent is readily volatile at room temperature. Upon application, the solvent readily volatilizes leaving regions of Increased porosity throughout the nail coating, These porous regions later facilitate' the entry of a remover solvent which may be acetone,

[0020] Non limiting examples of suitable Solvents include ethyl acetate, methyl acetate, and acetone.

EXAMPLE

[0021] Table 1 compares combinations of a volatile organic solvent with an atmospheric boiling point of about 55 - 80ºC, at least one of a volatile organic solvent with atmospheric boiling point > 240ºC, and at least one of a di-basic ester. Each experimental sample was prepared and evaluated as follows:

Note: Three (3) commercial nail coating remover products were used as controls in this study;

• Cutex Quick & Gentle Nail Enamel Remover-Regular: 23 rubs

• Cutex Nail Enamel Remover-Humactante: 23 rubs

• Cutex Non-Aceione Nail Enamel Remover. 27 rubs

Table 3: High Efficiency Nail Coating Remover Formulations (Ethyl Acetate-Based)

Note: Three (3) commercial nail coating remover products were used as controis in this study:

Cutex Quick & Gentle Nail Enamel Remover-Regular. 23 rubs

• Cutex Nail Enamel Remover-Humectante: 23 rubs

• Cutex Non-Acetone Nail Enamel Remover. 27 rubs

[0022] Raw ingredients were weighed Into clean 100-ml. sealable glass jars and were mixed thoroughly using a Red Devil Model 1400 Paint Conditioner for 5 minutes.

[00023]To demonstrate enhanced removal efficacy as a result of multiple raw ingredient synergies in the 18 experimental formulas tested herefn, the removal efficacy of each "neat" solvent (i.e.100% acetone, 100% ethyl acetate, 100% methyl acetate and 100% 100% propylene carbonate) also was behchmarked in this study.

[0024] TESTING METHODOLOGY:

[0025] To create a suitable test substrate for quantitative evaluation of removal efficacy, a series of drawdowns were cast onto clean glass panels using a Bird Film Applicator of 6 mil wet film thickness (Model # AP-3xOQ6SS; Paul N, Gardner & Co.) The test laoquer formula used in this study was Sinful Colors Nail Enamel Bahgin' Blue. This is a medium blue "glitter" shade containing 4.98% polyethylene terephthalate effects' pigments. This particular shade, is representative of a contemporary nail coating formu!ation that would be highty tenacious to users' nails and therefore would be quite difficult to remove completely after many days of wear. All drawdowns' were allowed to dry at ambient temperature (approximately 25 deg. C.) for at least 15 days before testing.

[0026) To provide a quantitative measurement of the relative removal efficacy of each experimental formula or control product evaluated herein, a clean cotton bait was saturated with the disclosed compositions then pressed gently onto the surface of the dried nail coating described above. The wet cotton ball then was rubbed in a clockwise motion within a circular test area approximately in diameter. The number of rubs needed to completely dissolve the

nail coating to bare glass was recorded for each test sample.
