Description

  The present invention relates to an aqueous beauty nail composition and a beauty nail applicator using the same, and more specifically, an aqueous beauty nail composition that is excellent in pigment dispersion stability and easily multicolored, and The present invention relates to a beauty nail applicator using the same.

  Conventionally, various nail polish compositions have been widely used for beautifully decorating fingertips, and in particular, organic solvent-based beauty nail composition having excellent coating properties and quick drying properties have been widely used. Since there is a problem that nails and skin become rough when an organic solvent-based beauty nail composition is used, in recent years, development of an aqueous beauty nail composition that has little influence on the human body has been widely promoted.

  An example of such an aqueous beauty nail composition is a skin coloring cosmetic containing at least water, a pigment, and a resin in Patent Document 1 (Japanese Patent Laid-Open No. 8-157329). At least one resin selected from the group consisting of acid copolymers, styrene-maleic acid copolymers, styrene-alkyl acrylate copolymers, styrene-alkyl maleate copolymers, and a base such as ammonia or amines. In addition, a skin coloring cosmetic composition has been proposed which further comprises at least one thickener selected from clay-based inorganic thickeners, inorganic fine particle thickeners, and polysaccharide thickeners.

  However, the dispersion stability of the pigment is generally a problem in the aqueous beauty nail composition, and even in the skin coloring cosmetic described in Patent Document 1, the pigment is not allowed to stand after standing for a long time. A hard cake is formed by sedimentation, and redispersion of the pigment by stirring or the like is extremely difficult.

  On the other hand, for example, Patent Document 2 (Japanese Patent Laid-Open No. 2013-124227) is characterized by containing at least 3 to 20% by mass of a plate-like pigment having a surface coated with a water-insoluble substance and water. An aqueous beauty nail composition has been proposed, and the aqueous beauty nail composition has excellent stability over time and does not easily form a hard cake even when the plate pigment settles. Redistribution is possible.

  However, in the aqueous nail polish composition described in Patent Document 2, it is necessary to use a plate-like pigment whose surface is coated with a water-insoluble substance. Etc. become difficult. In addition, it is difficult to say that the dispersion stability of the pigment is still sufficient.

JP-A-8-157329 JP 2013-124227 A

  In view of the circumstances as described above, an object of the present invention is to provide an aqueous nail care composition that is excellent in pigment dispersion stability and that can be easily multicolored, and a beauty nail applicator using the same. is there.

  As a result of intensive studies on the composition of the beauty nail composition and the structure of the beauty nail applicator to achieve the above object, the present inventor has stably dispersed mica in water using an appropriate dispersant. It was found that adjusting the beauty nail composition and constructing a beauty nail applicator using the beauty nail composition as a paint is extremely effective in achieving the above object, and the present invention has been achieved.

  That is, the present invention provides a beauty nail composition characterized by containing mica, water, and calcium carbonate. In the beauty nail composition of the present invention having such a configuration, since only mica is used as a pigment, it is easy to make multiple colors, and calcium carbonate particles are preferably used between mica particles and between layers. Since it can intervene, it is excellent in dispersion stability.

  In the beauty nail composition of this invention, it is preferable that content of the said mica, the said water, and the said calcium carbonate is 1-20 mass%, 35-75 mass%, and 4-25 mass%, respectively. .

  Moreover, in the beauty nail composition of this invention, it is preferable to contain carboxymethylcellulose sodium further, and it is preferable that content of the said carboxymethylcellulose sodium is 0.3 to 3 weight%, 0.4 More preferably, it is -1.3 mass%.

  In the nail material applicator of the present invention, the nail material composition is provided with a valve provided between the liquid storage part and the application part, and the valve is opened when the application part is pressed. Is preferably supplied to the application section (a mechanism used in a so-called direct liquid type valve-type pen).

  ADVANTAGE OF THE INVENTION According to this invention, the aqueous | water-based beautiful nail material composition which is excellent in the dispersion stability of a pigment, and can be easily multicolored, and the beautiful nail material applicator using the same can be provided.

It is an exploded view showing an example of composition concerning one embodiment of a beauty nail applicator of the present invention. It is an exploded view which shows the structural example of the valve mechanism 14 in FIG.

  Hereinafter, a preferred embodiment of the beauty nail composition and the beauty nail applicator of the present invention will be described in detail. In addition, the following description shows only one embodiment of the present invention, and the present invention is not limited by these, and redundant description may be omitted.

(1) Beautiful nail composition The beautiful nail composition of the present invention is characterized by containing mica, water, and calcium carbonate. Furthermore, it is preferable to contain sodium carboxymethylcellulose. Hereinafter, more specific embodiments of the beauty nail composition of the present invention having such a configuration will be described in detail.

  The mica (mica) used in the present invention is not particularly limited, and various conventionally known mica can be used as long as the effects of the present invention are not impaired. Since the beauty nail composition of the present invention is excellent in dispersion stability of mica in combination with calcium carbonate, it is not necessary to perform special surface treatment or surface coating on mica.

  Examples of mica include white mica, interference mica, colored mica, and silver mica, but it is preferable to use colored mica from the viewpoint of multicoloring. Here, the average particle diameter of the mica used is preferably 1 to 100 μm. This is because if the average particle size is 100 μm or less, good dispersibility can be exhibited, and if it is 1 μm or more, the unique color development and glitter of mica can be used effectively. The average particle diameter of mica can be measured using, for example, direct observation with various electron microscopes, a laser diffraction scattering method, or the like.

  White mica has a feature that its surface is coated with titanium dioxide, is translucent and has low hiding power. There are various kinds of particles. When the particles are large, they give a metallic luster, and when they are small, they give a soft silky luster.

  Interference mica has a feature that the coating layer of titanium dioxide is thicker than white mica, and the color tone changes depending on the thickness. Further, the interference mica has dichroism in which the front and the diagonal are complementary colors (red and green, blue and orange, yellow and purple, etc.) depending on the viewing angle.

  The colored mica is a mica that is coated with iron oxide on the titanium dioxide coating layer on the surface and colored with various colors. Colored mica is characterized by high hiding power.

  Silver-colored mica is a mica pigment that is obtained by further silver-plating a titanium dioxide coating layer and has a silver metallic feeling.

  The contents of mica and water in the beauty nail composition of the present invention are preferably 2 to 13% by mass and 40 to 65% by mass, respectively, and further 7 to 11% by mass and 50 to 60% by mass, respectively. It is more preferable that

  If the mica content is 2% by weight or more, the color development and brightness due to the mica can be fully exhibited, and if the mica content is 13% by weight or less, hard cake is formed due to the sedimentation and aggregation of the mica. This is because it is suppressed. Further, if the water content is 40% by weight or more, it sufficiently works as a dispersion medium for dispersing mica, and if the water content is 65% by weight or less, the mica is excessively diluted and viscous This is because mica sedimentation due to the decrease can be suppressed.

  In addition, although the water to be used is not specifically limited in the range which does not impair the effect of this invention, For example, a tap water, purified water, ion-exchange water, distilled water, a pure water etc. can be used.

  The beauty nail composition of the present invention contains calcium carbonate. The dispersion stability of mica can be improved by adding calcium carbonate. In addition, when only the above mica precipitates, the precipitate becomes very hard (hard cake formation), but by adding calcium carbonate, the precipitate becomes soft and redispersion of the pigment by stirring or the like becomes easy. . The mechanism of softening the precipitate by the addition of calcium carbonate is not necessarily clear, but it is considered that the calcium carbonate particles enter between the mica particles and between the layers.

  The particle diameter of the calcium carbonate to be added is preferably 0.05 to 1 μm, and more preferably 0.08 to 0.15 μm. This is because if the particle size of calcium carbonate is 1 μm or less, dispersion into the system is easy, and if it is 0.05 μm or more, the dispersed calcium carbonate can easily enter between the layers of mica.

  Moreover, in order to adjust the color development and glitter when the nail polish composition is applied to the nail, the hiding power of calcium carbonate, the diluting effect, and the like can be used. In the beauty nail composition of the present invention, the content of calcium carbonate is preferably 4 to 25% by weight. This is because if it is 4% by weight or more, it is sufficiently effective for the dispersion stability of mica and the suppression of hard cake formation, and if it is 25% by weight or less, it is possible to sufficiently exhibit the coloring and glitter caused by mica. Also, within this range, calcium carbonate can appropriately enter between the mica layers and can be easily redispersed, and the concealing effect of calcium carbonate can be exhibited. Note that alumina or the like, which is also an extender, may be used instead of calcium carbonate.

  The beauty nail composition of the present invention can contain sodium carboxymethyl cellulose. By adding carboxymethylcellulose sodium, the dispersion stability of mica can be improved more effectively. The content of sodium carboxymethyl cellulose is preferably 0.4 to 1.3% by weight, and more preferably 0.6 to 1.2% by weight.

  When sodium carboxymethylcellulose is added, carboxymethylcellulose sodium molecules penetrate between the mica particles and between the layers, and also between the mica and calcium carbonate, separating the mica from each other and improving the sliding between the mica and calcium carbonate. And increasing the viscosity of the system improves the dispersion stability of the mica.

  Furthermore, the dispersion stability of mica can be more effectively improved by adding both the calcium carbonate and sodium carboxymethylcellulose.

  In addition, in the beauty nail composition of the present invention, it is preferable to add a resin containing an acrylate ester in the molecule, and an alkyl acrylate copolymer is added, from the viewpoint of sticking property and mica dispersion stability. It is preferable.

The addition amount of the alkyl acrylate copolymer is preferably 10 to 40% by weight, and more preferably 15 to 30% by weight.

  Moreover, in the beauty nail composition of this invention, it is preferable to add sodium polyacrylate from a viewpoint of the dispersion stability of a calcium carbonate. In the beauty nail composition of the present invention, the content of sodium polyacrylate is preferably 0.5 to 10% by weight, and more preferably 2 to 5% by weight.
