Description

Technical Field

[0001] The present invention relates to a nail cosmetic.

Background Art

[0002] Functions required for nail cosmetics include ease of application, quick drying property, gloss of the coating film, and makeup retention. Recently, there has been a tendency to enjoy nail art by applying a nail cosmetic using an ultraviolet curable resin called gel nail, which is popular for its excellent gloss and makeup retention. However, the ultraviolet curable resin used in gel nail is difficult for individual consumers to use casually due to concerns about safety and difficulty of handling, and removal is also difficult with only a general-purpose remover and requires a visit to a specialty store. On the other hand, conventional general-purpose solvent-based nail cosmetics can be easily purchased by consumers at the store and removed easily, so they are favored by consumers for their high degree of freedom to change their nails according to their mood on the day, and still have the highest share in the nail market. However, there is a problem that the gloss and makeup retention are inferior compared to gel nail, and even in solvent-based nail cosmetics, better gloss and makeup retention are desired. In order to obtain excellent gloss and makeup retention, it is necessary to form a coating film with a uniform and uniform film thickness by applying evenly and in multiple layers on the nail, and it must be a nail cosmetic having appropriate usability that enables this.

[0003] Therefore, various studies have been conducted to improve the usability of nail cosmetics. For example, in a cosmetic containing an acrylic silicone copolymer having a specific structure, a technique for obtaining a cosmetic excellent in usability, adhesion, flexibility, and having a good color transfer prevention effect such as secondary adhesion (see, for example, Patent Document 1), or a polymer having a specific molecular weight composed of a silicone macromonomer having a specific structure as an essential component is dissolved or dispersed in a liquid component such as silicone oil and contained in a cosmetic to impart water resistance, adhesion, gloss, and persistence (see, for example, Patent Document 2), or a technique for improving the adhesion and durability to nails by containing diacetylated lysine or a salt thereof (see, for example, Patent Document 3) and the like have been proposed.

Prior Art Documents

[0004] [Patent Document 1] Japanese Patent Publication No. 2018-177673 [Patent Document 2] Japanese Patent Publication No. 2019-89715 [Patent Document 3] Japanese Patent Publication No. 2002-87936 [Disclosure of the Invention] [Problems that the invention aims to solve]

[0005] However, while the technology described in Patent Document 1 for nail beautifying agents prevents cracking and chipping of the coating film and provides good makeup retention, it still has issues with gloss, gloss retention, and stability over time, which are obtained from the uniformity of the coating film. Furthermore, while the technology described in Patent Document 2 provides the good spreadability and makeup retention characteristic of silicone oil, its effect on the stability of the formulation over time due to interaction with the gelling agent was insufficient. The technology described in Patent Document 3 is a technology that obtains durability by improving the adhesion between the nail beautifying agent and the nail, but its effect on gloss, gloss retention, and stability over time was insufficient. Therefore, there was a need to develop a nail beautifying agent that excels in gloss and gloss retention due to the uniformity of the coating film caused by smooth spreadability, as well as excellent stability of the formulation over time.

[0006] Therefore, the present invention aims to develop a nail polish that offers smooth spreadability, a uniform coating film resulting in excellent gloss and gloss retention, long-lasting wear, and long-term stability of the formulation. [Means for solving the problem]

[0007] In view of the above circumstances, the inventors conducted diligent studies and, as a result, discovered that by including the organically modified clay mineral in a specific ratio relative to the silicone oil in a nail care product containing a film-forming agent, an organically modified clay mineral, silicone oil, and an organic solvent, a nail care product with excellent smooth spreadability, uniform coating film, gloss and gloss retention, makeup longevity, and long-term stability of the formulation can be obtained, thus completing the present invention.

[0008] In other words, the present invention includes the following: [1] The following components (A) to (D); (A) Film-forming agent (B) Organically modified clay minerals (C) Silicone oil (D) Organic solvents A nail care product containing the following, wherein the mass ratio of component (B) to component (C) (B) / (C) is 0.1 or more and less than 10. [2] The nail beautifying agent according to [1], wherein the kinematic viscosity of component (C) at 25°C is 100 CS or less.

However, the present invention is not limited to the following preferred embodiments and can be freely modified within the scope of the invention. In this specification, percentages are expressed in mass unless otherwise specified. Also, in this specification, when a numerical range is expressed using "~", the range includes the values ​​at both ends.

[0011] Component (A), the film-forming agent, is a substance that forms a film after the volatile component evaporates in this invention. Film formation refers to the formation of a film after a solution in which the component corresponding to component (A) is dissolved at 40% in a solvent that is soluble in (e.g., ethyl acetate) is applied to a glass plate with a 400 μm thick applicator and dried at room temperature for 24 hours. Component (A) forms a film with appropriate strength and thickness on the nail surface, providing protection for the nail against physical stimuli and improving the longevity of the makeup. The film-forming agent of component (A) is not particularly limited, but an oil-soluble film-forming agent is preferred from the viewpoint of compatibility with component (D). The film-forming agent in the present invention is not particularly limited as long as it is commonly used in cosmetics, and examples include phthalic acid-based alkyd resins such as nitrocellulose, (phthalic anhydride / benzoic acid / glycerin) copolymer, (phthalic anhydride / trimellitic anhydride / glycols) copolymer, toluenesulfonamide resins such as (tosylamide / formaldehyde) resin, alkyl acrylate / styrene copolymer, (acrylates / dimethicone) copolymer, trimethylsiloxysilicate, polymethylsilsesquioxane, silicone resins such as (dimethicone / vinyltrimethylsiloxysilicate) crosspolymer, toluenesulfonamide epoxy resins such as sucrose benzoate ester (sucrose benzoate) and (tosylamide / epoxy) resin, polyvinyl alcohol, polyvinylpyrrolidone, vinylpyrrolidone / vinyl acetate copolymer, and dextrin isostearate.

"(H) Duration of Shine" evaluated the shine of the coating film after it had been applied to the nails and dried, assessing whether the shine had decreased after 24 hours of daily life compared to the initial state. "(ii) Smooth spreadability" was evaluated by assessing whether the sample spread evenly on the nail with light pressure without snagging when applied to the nail after shaking each sample well. <Absolute evaluation criteria> (Rating): (Evaluation) 4: Very good 3: Fairly good 2: Slightly bad 1: Very bad <Judgment criteria> (Judgment): (Average score of the ratings) AA: 3.8 points or higher A: 3.5 points or higher, less than 3.8 points B: 3.0 points or higher, less than 3.5 points C: 2.0 points or higher, less than 3.0 points D: Less than 2.0 points (Evaluation Method 2) "(e) Stability over time" was determined by filling each sample into a cylindrical glass bottle with a diameter of 4 cm and a height of 8 cm, storing it in a sealed state in a constant temperature bath at 50°C for one week, and visually observing the appearance of the sample according to the following criteria. <Judgment criteria> (Judgment) :(Judgment result) AA: There is no change in appearance and stability is good.
