  Further, the present invention provides a sheet base material comprising particles of a powder composition in which a liquid or powdery core component effective for skin care is encapsulated in a soft capsule and the capsule surface is coated with a fine powder. The present invention relates to a supported skin care sheet.
  Furthermore, the present invention provides a skin care effect on the skin by the particles of the powder composition carried on the sheet base material being transferred to the skin during use, and the particles being crushed by the pressure of a finger or the like and the core component exuding. The skin care sheet to give.

[Prior art]
  Conventionally, as a sheet-shaped cosmetic, representatively, paper white is known. Paper candy is produced by dissolving the addictive ingredients with water, applying them to paper with a roll and drying by heating. However, the paper drying process is complicated, and it is easy to cause variations in quality. There was a problem that it was easily altered by the heating process. In order to solve this problem, Japanese Patent Application Laid-Open No. 63-132815 discloses that a fluorinated hydrocarbon is mixed with a cosmetic ingredient to improve the drying problem when applied to paper. . However, since the oily ingredients are not blended in the conventional paper-type cosmetics, they have the disadvantage that they do not stick to the skin and cause powder floating, so that products such as paper-like foundations and paper-like eye shadows are used. Productization was difficult. For example, when an oil component is blended, the oil component is absorbed by the paper, and the cosmetic ingredients are changed, which is not practical. In order to solve this problem, Japanese Patent Application Laid-Open No. 1-143811 discloses that an oily component is encapsulated in a compressible and collapsible soft resin capsule so that the resin film of the capsule is destroyed and encapsulated by pressure of a finger or the like. It has also been proposed to encapsulate a microcapsule that releases an oily component in a paper form to obtain a paper-like cosmetic.
[0003]
  As described above, when microcapsules are produced by the conventional method of microencapsulation such as capsule coacervation, there is difficulty in reproducibility of the quality of compression-disintegrated microencapsulated products. However, there are problems that extra components are added or altered due to the chemical treatment of encapsulation, and that the manufacturing cost is high.
  On the other hand, many water-soluble or oil-soluble medicinal ingredients that generally act on the skin are used as skin care ingredients, but there are many chemically unstable ingredients, and the composition may change the composition and ingredients as a quasi drug. Since it is not allowed, powdering by chemical treatment by microencapsulation is difficult, and there is a problem in making a sheet-like skin care product.
[0004]
[Problems to be solved by the invention]
  As active ingredients for skin care, compounds having ultraviolet absorption, anti-skin roughening action, anti-inflammatory action, antibacterial action, anti-allergic action, whitening action, moisturizing action, antioxidant action and anti-aging action on skin are known. However, these compounds have a variety of water-soluble or oil-soluble compounds, and many of them have low stability. Even if these compounds are to be microencapsulated, other components are used during the encapsulation process as described above. There was a problem of adding or changing.
  Therefore, in the present invention, a solid and / or liquid core component effective for skin care is easily and economically powder-encapsulated without chemical treatment with alteration, convenient for carrying and used anytime. Providing a skin care sheet that can be used
  Further, in the present invention, in particular, with the advancement of women into society, cosmetics and skin care materials are not a bottle container storage type, but a sheet type or card type that is convenient to carry, and a disposable sheet type skin care product. The task is to do.
[0005]
[Means for Solving the Problems]
  In the present invention, a solid and / or liquid component effective for skin care is used as a core, and a powder capsule formed by enveloping the periphery of the core with fine powder cells is supported on a sheet base material. When used, the capsules are crushed to provide a dry type skin care product capable of providing a skin care effect.
  The sheet-like skin care product of the present invention is a powder that is transferred to the skin during use even if the skin care core component is in a solid form such as paper-white or in a liquid form such as a milky lotion, a cosmetic liquid or a whitening liquid. The capsule has an advantage that it is easily crushed by a pressing force of a finger or the like, and the active ingredient is separated and penetrates into the skin.
[0006]
  In the present invention, the active ingredient for skin care is used as the core ingredient, and the particles of the powder composition obtained by coating the core ingredient with the fine powder are supported on the sheet base material, and the particles are transferred to the skin during use. It is also possible to obtain a skin care product capable of giving an effective skin care effect to the skin by easily crushing the particles with a pressure such as, and leaching the active ingredient.
  At this time, the evaporation loss of the core component is prevented, the air is well shielded from the air, and the workability is excellent. The particles of the powder composition have an effect that cannot be obtained with a soft capsule alone, and even when the core component is a liquid component, the fine powder that covers the soft capsule has a smooth feeling when used and the stickiness is eliminated.
  The method of encapsulating the core component with a film and encapsulating it softly is known in both cases where the core component is liquid and / or solid. For example, in order to encapsulate the liquid core component, the pore diameter is sequentially increased. A seamless capsule coating solution is extruded from the outermost side of concentric multiple (triple) nozzles, a material solution that is easily oxidized from the innermost nozzle, and a material solution having low oxygen permeability and moisture permeability is simultaneously extruded from the intermediate nozzle into the cooling medium. This can be easily made (Japanese Patent Laid-Open No. 7-53356). As a capsule that is soft and can be easily squeezed with a finger, a spherical capsule of 0.2 to 2 mm is suitable.
[0007]

[0012]
  The core component effective for skin care can be used in a solid state that is easily absorbed by the skin, but it is more effective to use a liquid component. For example, as a solution or slurry, spray and agitate on a fine powder used in a cell. An effective forming means is a powder capsule.
  Examples of the solution include an aqueous solution and a solution using a non-aqueous solvent.
  Examples of the liquid component that can be preferably used for the core component of the present invention include a liquid composed solely of an oil component or a liquid or an emulsion mainly composed of an oil component.

  In the above-mentioned powder capsule of the present invention, a coloring agent and a fragrance can be appropriately added when encapsulating a solid and / or liquid skin care active ingredient.
  The obtained powder capsule is effective in protecting the core from oxidation and evaporation and stabilizing internal components as a capsule. After use on the skin, even if the core is oily, there is an advantage that a smooth feeling can be obtained by the particles of the cells.
[0015]
  In the powder capsule of the present invention, there is an advantage that the core of the active ingredient encapsulated by the pressure of a finger or the like is separated and acts directly on the skin, and the amount of the active ingredient contained is the powder composition Although the range of 1 to 50 wt% is possible on the basis, it is preferably 3 to 30 wt%, and the effect is low at 1 wt% or less, and powdering is impossible at 50 wt%.
