An embodiment of the present invention relates to a nail polish, and more particularly, to an aqueous nail polish composition capable of reversibly changing a color, pattern, or transmittance, a method of manufacturing the same, and a nail art method using the same.

Oil-based manicure, which is widely used in nail cosmetics, uses nitrocellulose as a film-forming agent, and uses plasticizers and diluents to give flexibility. In addition, the conventional oily nail polish uses an organic solvent added to control the drying time, and an organic solvent is also used as a remover for removing the nail polish. These oily manicures contain plasticizers that release environmental hormones and organic solvents, which are environmentally hazardous substances (VOCs), and are harmful to the human body, and problems such as fire hazard and hygienic environment of the remover are continuously raised. In addition, oil-based nail polish has the inconvenience of having to use a nail polish and a remover separately.

Since the conventional manicure or nail polish is composed of a specific color, there is a limit to creating an aesthetic effect on the nails with only one manicure or one nail polish. In order to produce a variety of colors, it is necessary to purchase a variety of colors of nail polish, resulting in an economic burden. Also, if you want to change the nail polish applied to your nails to a different color, you need to remove the existing nail polish or apply a new nail polish over it.

The technical problem to be achieved by an embodiment of the present invention is to provide an aqueous nail polish composition capable of reversibly changing a color, pattern, transmittance, etc. after being applied to a nail or toenail, and a nail art method using the same.

In order to achieve the above technical problem, an example of an aqueous nail polish composition according to an embodiment of the present invention includes a water dispersion base; And microcapsules including magnetic particles.

An example of a method of manufacturing an aqueous nail polish composition according to an embodiment of the present invention to achieve the above technical problem is a solvent in which magnetic particles are dispersed and a solvent in which a polymer constituting the capsule wall is melted is ultrasonically stirred and stirred. , Generating microcapsules by mixing by using at least one of vibration and high voltage application; Creating an aqueous dispersion base comprising a polymer; And mixing the aqueous dispersion base and the microcapsules.

In order to achieve the above technical problem, an example of a nail art method according to an embodiment of the present invention includes the steps of applying an aqueous nail polish composition to the nails; Drying the aqueous nail polish composition applied to the nails; And applying an electric or magnetic field to the nail to form a color or pattern.

According to an embodiment of the present invention, even after applying the aqueous nail polish composition to a nail or toenail and drying it, the color, pattern, or transmittance may be reversibly changed. In addition, since it is a water-based nail polish formulated based on water, it is not only harmless to the human body, it dries easily, does not need a remover when removed, and can be easily removed like a sticker.

The magnetic particles 140 may be formed in a plate shape, a sphere shape, a cluster shape, a core-shell shape, or other shapes similar thereto. The magnetic particles 140 may have a diameter or length of 10 nm to 150 μm. Preferably, the diameter or length of the magnetic particles 140 may be 0.5 ~ 150㎛. This embodiment shows the microcapsule 110 including one magnetic particle 140 in a plate shape for convenience of description.

The magnetic particles 140 are particles having a magnetic or electric charge so as to be able to move or rotate according to a magnetic or electric field applied from the outside, and may be dispersed in the solvent 150 in the myslow capsule 110.

Magnetic particles 140 are iron (Fe), nickel (Ni), cobalt (Co), titanium (Ti), carbon (C), zinc (Zn), sulfur (S), gold (Au), silver (Ag) , Barium (Ba), strontium (Sr), lead (Pb), aluminum (Al), tungsten (W), molybdenum (Mo), and other elements, or a material including oxides thereof.

It can be made using one or more of the methods of application. An example of a photograph taken by enlarging an aqueous nail polish composition of various colors including the encapsulated magnetic particles 140 is shown in FIGS. 6A to 6C.

2 is a diagram schematically showing a principle in which the color of an aqueous nail polish according to an embodiment of the present invention changes reversibly. For convenience of explanation, FIG. 2 shows a microcapsule including one magnetic particle in a plate shape.

Referring to FIG. 2, a nail polish composition applied to a nail exhibits a first color when a magnetic field or the like is not applied from the outside (200). The first color may be an achromatic color or a chromatic color according to an embodiment. For example, the first color may be determined according to the color of the pigment or microcapsules added to the water dispersion base of the nail polish composition.

When a magnetic field is applied to the nail polish composition applied to the nail (210, 220), the magnetic particles in the microcapsules move or rotate according to the direction of the magnetic field, and accordingly, the nail polish composition 210, 220 produces a second color different from the first color. Show. Since the solvent in the microcapsule is not cured, a magnetic field is applied even after the nail polish composition is applied to the nails and dried, so that the color, pattern, or transmittance of the nail polish composition can be reversibly changed.

When light enters the nail polish composition, a specific wavelength (that is, a specific color) is reflected by magnetic particles of the microcapsule and a colorant of a water dispersion base. When the magnetic particles move or rotate in the microcapsule and their arrangement is changed, the wavelength (ie, color) or angle of light reflected from the nail polish composition changes. For example, assuming that the direction of incident light to the nail polish composition is a vertical direction in the figure in Fig. 2, when magnetic particles are arranged horizontally, light of the first wavelength is mainly reflected by magnetic particles, and When the particles are arranged vertically, the incident light is mainly reflected by a water-dispersion-based colorant or the like, so that different colors are expressed. That is, the ratio of various types of wavelengths reflected by the nail polish composition may vary according to the movement or rotation of the magnetic particles, and various colors may be expressed accordingly.

Referring to FIG. 3, when a magnetic field is not applied to a nail polish composition applied to a nail (300), a first color is expressed. When a magnetic field in the first direction (eg, vertical direction) is applied 310, the nail polish composition applied to the nail is changed to a second color. When the direction of the magnetic field is changed to a second direction (eg, a horizontal direction) (320), the nail polish composition applied to the nail is changed to another third color. That is, as shown in FIG. 2, as the magnetic particles in the nail polish composition are arranged horizontally or vertically according to the direction of the magnetic field, the wavelength of the reflected light is changed and the color is changed. An exemplary embodiment in which the color of the nail polish composition applied to the nails is changed is shown in FIG. 4.

A shape or pattern may be formed by partially changing the color of the nail polish composition applied to the nails without changing the color as a whole (330, 340, 350). For example, when a magnetic field of stripes at regular intervals is applied (330), the arrangement of magnetic particles of the microcapsules located in a portion affected by the striped magnetic field is changed to form a striped pattern on the nail. When the pattern of the magnetic field is a wave pattern or an oblique pattern (340, 350), a corresponding pattern is formed in the nail polish composition applied to the nail. An exemplary embodiment of changing the pattern of the nail polish composition applied to the nail is illustrated in FIG. 5.

After that, stevioside and pigment are added and uniformly mixed for 10 minutes using a disper continuously. Finally, after adding ethanol, the mixture is uniformly stirred for 5 minutes to prepare a liquid dispersion base having a white viscosity. A nail polish composition can be obtained by mixing the prepared aqueous dispersion base and the capsule.

In the case of showing a blue manicure as shown in FIGS. 7 and 8, a mica pearl pigment with 0.1% by weight of blue No. 1 and a particle size of 5 to 50 μm on the aqueous dispersion base (70% mica, 2% tinoxite, tati Nium dioxite 28%) 0.9% w weight part may be added. Even if the color is the same blue, nail polish compositions having different feelings can be prepared according to the type of mica pearl pigment. The nail polish composition is applied to the surface of the nail, dried for 3 to 5 minutes, and then a magnet of a specific pattern is placed on the nail for 5 seconds to obtain a pattern as shown in FIG. 7 or 8.

9 and 10, in the case of displaying a green manicure, a mica pearl pigment with a particle size of 5 to 50 μm (maica 70%) with 0.05% by weight of blue No. 1 and 0.2% by weight of yellow No. 4 on the water dispersion base. , Tin oxide 2%, titanium dioxide 28%) 0.75% by weight may be added. Even if the color is the same green, nail polish compositions having different feelings can be prepared according to the type and particle size of the mica pearl pigment. A nail polish composition is applied to the surface of the nail, dried for 3 to 5 minutes, and then placed on the nail for 5 seconds to obtain a pattern as shown in FIGS. 9 and 10.

Even with the same wine color, nail polish compositions having different feelings can be prepared depending on the type and particle size of the miker pearl pigment. The nail polish composition is applied to the surface of the nail, dried for 3 to 5 minutes, and then placed on the nail for 5 seconds to obtain a pattern as shown in FIGS. 11 and 12.

In the case of displaying a violet manicure as shown in FIG. 13, 1% by weight of a mica pearl pigment (70% mica, 2% tin oxide, 28% titanium dioxide) may be added to the aqueous dispersion base. A nail polish composition is applied to the surface of the nail, dried for 3 to 5 minutes, and then placed on the nail for 5 seconds to obtain a pattern as shown in FIG. 13.

That is, as shown in FIG. 14, a nail polish composition of various colors may be prepared by mixing pigments of different colors with the water dispersion base of [Table 1].

An example in which the aqueous nail polish composition produced according to each preparation example in Table 3 was applied and the pattern was changed is shown in FIG. 15.

Referring to FIG. 15, a difference in characteristics according to the microcapsule content of the first preparation example to the third preparation example can be confirmed. As the amount of microcapsules increases, the color characteristics of the pattern generated when a magnetic field is applied are excellent. However, as the amount of microcapsules increases, the viscosity increases, and there is a disadvantage that bubbles are generated when applying the aqueous nail polish composition to nails.

Referring to FIG. 16, when a blue water-based nail polish is applied and a magnet with a wave pattern is placed on it, a blue wave pattern is formed on the nail polish. To remove the wave pattern, simply place a flat magnet on your fingernail. Since the nail polish composition of this embodiment is water-based, not oily, it can be easily removed from the nail without a separate remover.
