Summary of the Invention

Problems to be Solved by the Invention

[0004] Liquid type double eyelid cosmetics that adhere to or form a film on the eyelids, etc., use a resin that is difficult to fall off for the purpose of maintaining durability, so there is a problem that it cannot be easily removed with a cleansing agent. Also, when containing pearl powder, the pearl powder is likely to aggregate, and there are also problems in the finish.

Means for Solving the Problems

[0005] The present inventors have found that by using a silicone-based film-forming agent in combination with a volatile oil and a metal oxide-coated plate-like powder, it is possible to obtain an external preparation for skin adhesion that is extremely excellent in durability, can be easily removed with a cleansing agent, has a strong pearl feeling, and has a uniform and beautiful finish, and completed the present invention.

[0006] The present invention comprises the following components (A), (B) and (C): (A) Silicone-based film-forming agent: 1 to 20% by mass, (B) Volatile oil, (C) Metal oxide-coated plate-like powder: 0.01 to 20% by mass It relates to a topical skin adhesive containing the same.

[0007] The present invention also relates to a method for attaching a three-dimensional object, which comprises applying the topical skin adhesive to the skin and then placing the three-dimensional object on the skin surface.

Effects of the Invention

[0008] The topical skin adhesive of the present invention is very excellent in persistence and can be easily removed with a cleansing agent. Further, when applied to the skin, the metal oxide-coated plate-like powder is uniformly dispersed on the surface of the coating film, resulting in a stronger pearl feeling and a bright finish. The finish when creating double eyelids or wearing false eyelashes is also bright and beautiful.

[0093] Organically modified clay minerals can also be used as a dispersion diluted with a solvent in terms of improving workability and excellent thickening effect of oil. Specifically, it is preferable to use a premix gel in which the organically modified clay mineral is previously dispersed in a solvent. The solvent is not limited as long as it can be thickened by the organically modified clay mineral, but from the viewpoint of the thickening effect of oil, octyldodecanol, mineral oil, etc. are preferable. Further, from the viewpoint of efficiently dispersing the organically modified clay mineral to exhibit the thickening effect, it is preferable to contain polar additives such as propylene carbonate, ethanol, water, and various surfactants. The content of the organically modified clay mineral in the premix gel is preferably 5 to 25% by mass, more preferably 8 to 20% by mass, and further preferably 10 to 18% by mass from the viewpoints of improving workability, the thickening effect of oil, and suppressing oil separation of the thickened oily gel itself. As the premix gel, commercially available products such as benton gel EUGV containing 10% by mass of cation-modified clay mineral, benton gel MIOV, benton gel ISDV, benton gel VS-5 PCV containing 18% by mass, and benton gel PTM containing 15% by mass (all of the above are manufactured by Elementis Japan Co., Ltd.) can be used.

[0095] In addition to the above components, the external skin adhesive agent of the present invention can optionally use various commonly used components as long as the effects of the present invention are not impaired. These components include, for example, oily components other than the above, surfactants, water, water-soluble polymers, antioxidants, ultraviolet absorbers, vitamin agents, preservatives, pH adjusters, fragrances, plant extracts, moisturizers, colorants, cooling agents, antiperspirants, bactericides, skin activators, and the like.

[0096] The external skin adhesive agent of the present invention can be produced by a conventional method and can be applied to any form such as an oily composition or an emulsified composition. As a preparation, it can be applied in the form of a liquid, emulsion, paste, cream, gel, solid, etc. When the external skin adhesive agent of the present invention is applied to the skin, the metal oxide-coated plate-like powder of component (C) is uniformly dispersed on the surface of the coating film, so that the cleansing agent is easily impregnated and the adhesive coating film is easily broken. Therefore, although the persistence is very excellent, it can be easily removed with a cleansing agent.

[0097] The external skin adhesive agent of the present invention can be an external skin adhesive agent for the eye area for creating double eyelids or an external skin adhesive agent for double eyelid formation. To create double eyelids using the external skin adhesive agent of the present invention, for example, as shown in FIG. 1, after applying it to the whole or a part of the eyelid (coating film type, adhesive type), dry it to form double folds. In addition, the external skin adhesive agent of the present invention can also be used as a makeup cosmetic such as an eyeliner.

[0098] After the external skin adhesive agent of the present invention is applied to the skin, a three-dimensional object can be placed on the skin surface and used for attaching the three-dimensional object. Examples of the skin site to which the external skin adhesive agent of the present invention is applied include the eyelid and its peripheral part, ear, nose, cheek, finger, hand, arm, etc. Examples of the three-dimensional object placed on the skin surface include granular substances, films, fibers, flat objects, etc.

[0099] The term "granular material" refers to solid materials with a particle width of 1 mm or more and 5 mm or less. Specifically, examples include metal particles, resin particles, stones, and shells. For example, resin particles include beads and particles with colored outer surfaces of resin particles. Stones include rhinestones and gemstones. Among these, from the viewpoints of decorativeness, adhesion, followability, safety, etc. when applied to the skin, one or more selected from metal particles, resin particles, and stones are preferred. Here, the particle width means the diameter when the granular material is spherical, the maximum width when it is non-spherical, or the size measured by the sieving method.

[0100] Examples of the film include solid materials other than the aforementioned granular materials, such as paper, metal foil, resin film, films colored or metal-vapor-deposited thereon, and films with granular materials attached thereto. Examples of paper include Japanese paper and kraft paper. Examples of metal foil include gold foil, silver foil, and other metals. Examples of resin film include films such as nylon film and polyethylene film. Examples of colored or metal-vapor-deposited films include hologram films. Among these, from the viewpoints of decorativeness, adhesion, followability, and safety when applied to the skin, paper, metal foil, and resin film are preferred.

[0101] Examples of fibers include plant fibers such as cotton and hemp, animal fibers such as silk and wool, regenerated fibers such as rayon and cupra, semi-synthetic fibers such as acetate, and synthetic fibers such as nylon and polyester, and mixtures thereof are also included. Also, false eyelashes are included. False eyelashes are artificial eyelashes that can be attached to the eyelids or eyelashes, and there is no limitation as long as it is what is used for ordinary false eyelashes. For example, "Quick Extension" manufactured by D.A.UP Co., Ltd., "Dolly Wink Salon Eyelash" manufactured by Cozy Honpo Co., Ltd., etc. can be mentioned.

[0102] The flat objects are flat objects other than the aforementioned granular objects. For example, the thickness is preferably 0.1 mm or more, more preferably 0.5 mm or more, preferably 5 mm or less, more preferably 2 mm or less, and those with a maximum width exceeding 5 mm are included. Examples of the flat objects include metal plates, plastic plates, rubber plates, fabrics such as woven fabrics and non-woven fabrics, pressed flowers, natural objects such as plants, shells, and eggshells.

[0103] In addition, as three-dimensional objects other than the above, solid objects with both width and height exceeding 5 mm are excluded, and solid objects having voids or unevenness such as accordion shapes and flowers are included.

[0104] These three-dimensional objects may be placed on the skin surface after applying the skin-adhesive external preparation of the present invention to the skin, and can be placed quickly and uniformly.
