Provided herein are compositions, kits, and methods useful for preparation of artificial nails, such as acrylic nails or dip powder nails, with a photochromic color agent that changes color reversibly upon exposure to light.
Artificial nails have been used for centuries to decorate and enhance the beauty of human hands. Although early artificial nails used natural materials, modern methods of preparing artificial nails use polymers, such as polyacrylate, as the nail material. These new materials allow the incorporation of new color or contrast elements.
Therefore, there is a continuing need for compositions, kits, and methods useful for preparation of artificial nails with novel, attractive features that enhance their esthetic appeal or their other properties.
Provided herein are compositions, kits, and methods useful for preparation of artificial nails (e.g., acrylic nails; dip powder nails) with photochromic color agents. In certain embodiments, the photochromic color agent changes color reversibly upon exposure to light (e.g., ultraviolet light; sunlight).
In certain embodiments, provided herein are artificial nail precursor compositions, the composition including:
In certain embodiments, provided herein is the artificial nail precursor composition as otherwise disclosed, wherein the polyacrylate precursor comprises poly(methyl methacrylate) (PMMA). In certain embodiments, the polyacrylate precursor comprises 2-cyanoacrylate.

When referring to the compounds provided herein, the following terms have the following meanings unless indicated otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. In case of a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.
All publications, patent applications, patents, and other references mentioned herein are incorporated herein by reference in their entirety. In case of conflict, the present application will control.
The articles “a,” “an,” and “the” as used herein not only include certain embodiments with a single member, but also may include embodiments with more than one member. For example, an aspect “comprising a photochromic color agent and a photochromic glitter” should be understood as presenting certain embodiments with at least a second photochromic color agent, at least a second photochromic glitter, or both.
Similarly, the term “or” as used herein is a Boolean “or,” unless the alternatives cannot be combined without logical incompatibility. For example, an aspect “comprising a photochromic agent selected from A, B, or C” should be understood as applying to embodiments comprising A and B; B and C; A and C; or A, B, and C.
The term “about” as used herein to modify a numerical value indicates a defined range around that value. If “X” were the value, “about X” would generally indicate a value from 0.95X to 1.05X. Any reference to “about X” specifically indicates at least the values X, 0.95X, 0.96X, 0.97X, 0.98X, 0.99X, 1.01X, 1.02X, 1.03X, 1.04X, and 1.05X. Thus, “about X” is intended to teach and to provide written description support for a claim limitation of, e.g., “0.98X.” When “about” is applied to the beginning of a numerical range, it applies to both ends of the range. Thus, “from about 5 to 20%” is equivalent to “from about 5% to about 20%.” When “about” is applied to the first value of a set of values, it applies to all values in that set. Thus, “about 7, 9, or 11%” is equivalent to “about 7%, about 9%, or about 11%.”
The term “color agent” as used herein, and unless otherwise specified, refers to a compound or mixture of compounds added to a composition to impart a particular color to the composition. In certain preferred embodiments, one or more color agents is photochromic (i.e., a photochromic agent).
The term “cuticle” as used herein, and unless otherwise specified, refers to the thin layer of dead skin proximate to the eponychium on the nail bed.
The term “eponychium” as used herein, and unless otherwise specified, refers to the living tissue at the base of the nail bed closer to the palm.
The term “nail plate” as used herein, and unless otherwise specified, refers to a hard, exposed portion of the flat, unliving, keratin-rich tissue at the end of the fingers and toes. The nail plate or a portion thereof is the site of attachment for the artificial nail.
The term “photochromic” as used herein, and unless otherwise specified, refers to a property of changing color upon exposure to light (e.g., daylight; ultraviolet light).
The term “polyacrylate” as used herein, and unless otherwise specified, refers to a polymer of an R1(CO)CR2═CR3(R4) monomer (i.e., an acrylate) or (NC)CR2═CR3(R4) monomer (i.e., a cyanoacrylate). In a preferred embodiment, R1 is C1-6alkyl or C1-6alkyoxy, and R2, R3, and R4 independently selected from the group including H and C1-6alkyl (e.g., methyl). In certain embodiments, a polyacrylate is prepared from a monomer or mixture of monomers selected from ethyl acrylate, methyl acrylate, ethyl methacrylate, methyl methacrylate, or 2-cyanoacrylate. In certain embodiments, a polyacrylate is prepared from a derivative of acrylic acid (e.g., an acrylate ester) or mixture of such derivatives.
All percentage compositions are by weight (i.e., w/w) unless otherwise noted.
In certain embodiments, provided herein are artificial nail precursor compositions, the composition including:

As used herein, the symbols and conventions used in these processes, schemes and examples, regardless of whether a particular abbreviation is specifically defined, are consistent with those used in the contemporary technical literature.
For the following examples, standard application methods known to those skilled in the art can be used. All treatments are conducted at room temperature unless otherwise noted.
To a container is added ethyl methacylate powder (1 part) and a photochromic agent (1 part) that turns from white to purple upon exposure to ultraviolet light. The container is closed, and the components are mixed by shaking until they are approximately homogeneous.
A nail is cleaned, trimmed, and gently buffed. If necessary to provide a better surface, the cuticles are removed and the eponychium is gently pushed back. The nail surface is treated with nail primer, which is allowed to dry. A drop of glue is applied to an artificial nail. The artificial nail is then carefully applied to the buffed nail without touching the glue to the epinychium or the tissue around the nail.
The liquid activator and the photochromic nail powder of Example 1 are placed in separate containers and combined (e.g., with a brush) to prepare a small, moist ball of artificial nail precursor material. This artificial nail precursor material is applied onto the nail tip with a brush to form the nail, with care taken not to paint the precursor material onto the flesh around the nail. The new acrylic nail is allowed to dry (i.e., to cure). Optionally, glitter or a coat of polish (e.g., a clear, protective coat) is applied to the acrylic nail after curing.
A clean nail is painted with a thin, even layer of a commercially available base gel. If necessary to provide a better surface, the cuticles are gently pushed back. Before the base gel dries, the nail is treated with the photochromic nail powder of Example 1, either by dipping the nail into the nail powder or by pouring the nail powder onto the nail. Any excess powder on the nail was removed by tapping. The dip or glitter is gently pushed down or off the surrounding surfaces if needed.
A dip powder activator is then painted on the dip-powder-coated nail to cure the artificial nail. At least one coat of the activator is applied, then allowed to cure before application of another coat of activator, glitter, or a coat of polish (e.g., a top or protective coat).
