Description

  The present invention relates to a cosmetic patch, and more particularly, to a cosmetic patch that allows a cosmetic ingredient to efficiently penetrate into the skin.

  Normally, human skin is kept in a certain moist state by moisture and fat supplied from the skin tissue, but due to various factors such as constitution and health, climate and moisture in the atmosphere, Become. When the skin is dry, it becomes easy to cause various skin disorders such as itching and a feeling of tension on the skin, the surface of the skin being crumpled, roughened, and wrinkles becoming deep. Therefore, in order to prevent such dryness of the skin, a cosmetic application agent such as a milky lotion, a cosmetic liquid, a cream or an oil containing a moisturizing component is applied.

  In recent years, in addition to preventing skin dryness, emollient ingredients to make the skin surface smooth and soft, whitening ingredients to improve stains and dullness, skin active ingredients to revitalize skin, rough skin improvement ingredients to improve rough skin Cosmetic coating agents containing a skin tightening component that tightens the skin are also used.

  Since the cosmetic coating agent as described above is usually in a liquid or emulsified state or a paste state, when used as a pack, the sheet is impregnated with the cosmetic coating agent, and the sheet is applied to the skin. After applying the cosmetic coating agent thicker than usual, it took time and effort, such as covering with a sheet.

  Therefore, in recent years, facial masks (also referred to as face masks) and sheet-like cosmetics in which a sheet made of nonwoven fabric or the like is impregnated with a liquid pack cosmetic and individually wrapped in an encapsulating bag are commercially available. .

  As such a face mask, for example, a sheet piece composed of a non-woven fabric is formed into a mask size large enough to cover the face, and this sheet piece is impregnated with a cosmetic solution. In the vicinity of both cheeks, there has been proposed one in which cut lines for folding and overlapping sheet pieces are formed. (For example, refer to Patent Document 1).

  In addition, as a sheet-shaped cosmetic excellent in slimming effect, swelling prevention / improvement effect, skin-squeezing effect, and skin care effect, a sheet-shaped cosmetic containing yellow flower vegetables or an extract thereof has been proposed. (For example, refer to Patent Document 2).

FIG. 5 is an explanatory diagram showing a state in which the cosmetic adhesive material according to the embodiment of the present invention is applied to the user's face.

  Next, a cosmetic patch according to an embodiment of the present invention will be described with reference to the drawings. In addition, embodiment described below is the illustration for demonstrating this invention, and this invention is not limited only to these embodiment. Therefore, the present invention can be implemented in various forms without departing from the gist thereof.

  FIG. 1 is a cross-sectional view of a cosmetic patch according to an embodiment of the present invention. In the drawings, for easy understanding, the thickness, size, enlargement / reduction ratio, etc. of each member are not matched with the actual ones.

  A cosmetic patch 1 shown in FIG. 1 includes a base layer 11, an adhesive layer 12 disposed on one side of the base layer 11, and an adhesive layer 12 of the base layer 11. A carrier layer 13 disposed on a surface opposite to the surface, and a separator layer 14 disposed on a surface opposite to the surface on which the base material layer 11 of the adhesive layer 12 is disposed. It is prepared for. The adhesive layer 12 contains a cosmetic component 15.

  The base material layer 11 has a thickness of 1 to 10 μm and is composed of a layer mainly composed of a polyurethane elastomer having a glass transition temperature of 0 ° C. or lower. This polyurethane elastomer is an elastomer having a urethane group in the molecule, and is produced by a polyaddition reaction of a polyol component and a diisocyanate component. As the polyol component, a long-chain diol is used. In addition, a short-chain diol may be used in combination as a chain extender. In addition, a crosslinking agent such as a monomolecular polyol such as trimethylolpropane, glycerin, or sorbitol may be used. The technology for producing polyurethane elastomers is well known in the art.

  Polyurethane elastomers are classified according to the type of polyol component because the type of polyol component constituting the soft segment greatly affects the properties. Specifically, the polyurethane elastomer includes (1) a caprolactone type polyurethane elastomer synthesized by polyaddition reaction of polylactone ester polyol obtained by ring-opening polymerization of caprolactone and diisocyanate, and (2) adipine of adipic acid and glycol. Adipic acid ester type polyurethane elastomer synthesized by polyaddition reaction of acid ester polyol and diisocyanate, and (3) by polyaddition reaction of polyether polyol such as polytetramethylene glycol obtained by ring-opening polymerization of tetrahydrofuran and diisocyanate. They are roughly classified into synthesized polyether type polyurethane elastomers.

  The polyurethane elastomer is excellent in mechanical properties such as tensile strength and tear strength, abrasion resistance, low temperature properties, flexibility, and the like, and the thin film is excellent in ultraviolet absorption, water absorption, moisture permeability, and the like. The cosmetic patch 1 having a base material layer 11 made of a thin film mainly composed of polyurethane elastomer is well suited to fine irregularities such as wrinkles and skin grooves, and does not feel uncomfortable when applied to the skin. .

  In the cosmetic patch 1 using the polyurethane elastomer thin film as the base material layer 11, the base material layer 11 has water absorption and moisture permeability, and therefore, sweat hardly accumulates on the skin application site or causes stuffiness. Therefore, the cosmetic patch 1 is extremely unlikely to cause blurring or itching at the site of application. In addition, since the polyurethane elastomer thin film is water-absorbing and easily blends with water, it is easy to apply cosmetics. Among these polyurethane elastomers, polyether type polyurethane elastomers are preferable in that they can exhibit an excellent overall function as the base material layer 11 of the cosmetic patch 1.

  Examples of the diisocyanate include aromatic diisocyanates such as tolylene diisocyanate, diphenylmethane diisocyanate, polymethylene polyphenylene polyisocyanate, tolidine diisocyanate, and naphthalene diisocyanate; hexamethylene diisocyanate, isophorone diisocyanate, xylylene diisocyanate, dicyclohexylmethane diisocyanate, hydrogenated xylene diisocyanate, and the like. Of aliphatic diisocyanates; and the like, but is not limited thereto.

  The caprolactone type polyurethane elastomer uses a polylactone ester polyol obtained by ring-opening polymerization of caprolactone as a polyol component. The adipic acid ester type polyurethane elastomer uses an adipic acid ester polyol of adipic acid and glycol as a polyol component. The polyether type polyurethane elastomer uses a bifunctional polyether polyol such as poly (oxypropylene) glycol (PPG) or poly (oxytetramethylene) glycol (PTMG) as a polyol component.

  As a polyether type polyurethane elastomer suitable for the present invention, commercially available Elastollan (registered trademark) (1180A, 1190ATR, 1195ATR, 1198ATR, 1154D, 1164D, ET385, ET880, ET885, ET890, ET858D, available from BASF Japan Ltd. , ET860D, ET864D, NY90A, NY97A, ET370), Milactolan (registered trademark) (E300 series, P300 series) of Nippon Milactolan Co., Ltd., Rezamin (registered trademark) (P-2000 series) of Daiichi Seika Kogyo Co., Ltd. Pandex (registered trademark) of Bayer Polymer Ltd. (T8175, T8180, T8185, T8190, T8195, D) 9370A, 5377A, 588, may be mentioned KU2-8659, DP5094A) or the like.

  The glass transition temperature (Tg) of the polyurethane elastomer is 0 ° C. or lower, preferably −10 ° C. or lower. The lower limit of the glass transition temperature is about -70 ° C. The glass transition temperature can be measured using a differential scanning calorimeter (DSC). When the cosmetic patch 1 is affixed to the skin surface having an average body temperature of 36.5 ° C., the flexibility of the cosmetic patch 1 can be ensured by the low glass transition temperature of the base material layer 11. When the cosmetic patch 1 is affixed to the skin, if the base material layer 11 is excellent in flexibility, it is easy to apply cosmetics (good makeup is applied). If water is applied to the surface of the base material layer 11 of the cosmetic patch 1 that is being applied before applying the cosmetic, the base material layer 11 made of polyurethane elastomer becomes soft and becomes more familiar with the skin surface. The ride will be good. Since the polyurethane elastomer has a low glass transition temperature, it has excellent flexibility at a temperature near body temperature, and is excellent in adaptability to the skin surface, applicability of cosmetics, and the like.

  The thickness of the base material layer 11 is in the range of 1 to 10 μm, preferably 1 to 8 μm, more preferably 1 to 6 μm, and still more preferably 1 to 5 μm. When the thickness of the base material layer 11 is in the range of 1 to 10 μm, the cosmetic patch 1 conforms to the minute unevenness of the skin, easily follows the movement of the skin, and the applied portion becomes inconspicuous. When the thickness of the base material layer 11 is less than 1 μm, the strength of the base material layer 11 is not sufficient, and the base material layer 11 may be cut during application or when the cosmetic patch 1 is peeled off from the skin. is there. On the other hand, when the thickness of the base material layer 11 exceeds 10 μm, in addition to making the sticking part conspicuous, compatibility with the surface of the skin and followability to the movement of the skin are reduced.

  When the thickness of the base material layer 11 is extremely thin, moisture permeability can be improved. The extremely thin polyurethane elastomer layer is excellent in water absorption and moisture permeability, so that sweat or moisture accumulates at the application site of the cosmetic patch 1, causing blurring and itching, and inhibiting the protection of damaged parts. Very few.

  Since the cosmetic patch 1 of the present invention has a thin base material layer 11 made of polyurethane elastomer and is excellent in flexibility, it adheres to the skin when it is applied by pulling a part of the skin with wrinkles or sagging skin. When the tension is released, the skin enters into the skin groove, wrinkles and the like. Therefore, the cosmetic patch 1 is in a state of being folded on the surface of the skin with wrinkles and the like, and the applied site looks flat, and as a result, the effect of appearing to reduce wrinkles or sagging can be achieved.

  The back surface of the base material layer 11 (the surface of the base material layer 11 on the side where the adhesive layer 12 is not provided) is desirably embossed. Embossing can be performed by passing a polyurethane elastomer film through an embossing roll. When the polyurethane elastomer layer is formed by a solution casting method, embossing can be performed by a method of casting on a carrier layer (support to which the solution is applied) having fine irregularities on the surface. Fine irregularities on the surface of the carrier layer are transferred to the polyurethane elastomer layer. Therefore, in the present invention, the embossing includes not only mechanical treatment using an embossing roll but also other methods that can form fine irregularities on the surface of the polyurethane elastomer layer.

  The degree of the embossing treatment can be quantitatively evaluated by the glossiness of the back surface of the base material layer measured at an angle of 60 degrees. In the Japanese Industrial Standard (JIS Standard), as a glossiness standard, a reflectance of 10% measured at an incident angle of 60 degrees on a glass surface having a refractive index of 1.567 is used as a glossiness of 100%. In the present invention, micro-TRI-gross (manufactured by Toyo Seiki Co., Ltd.) is used as a gloss meter, and the gloss is measured at an angle of 60 degrees.

  The glossiness of the back surface of the base material layer 11 is in the range of 0.5 to 7.5, preferably 1 to 6. By embossing the base material layer 11 so that the glossiness of the base material layer 11 made of polyurethane elastomer is within the above range, the appearance of the cosmetic patch 1 is not felt unnaturally from the appearance. In addition to being able to be made, the application of cosmetics becomes even easier.

  The cosmetic patch 1 of the present invention has a touch feeling similar to that of healthy skin because the base material layer 11 is made of polyurethane elastomer. Skin such as scars and keloids are often slippery like the surface of a plastic film because the texture of healthy skin is lost. Depending on the type of skin disease, excessive unevenness, texture irregularity, dryness, etc. may occur on the skin, resulting in a rough and rough feel. When the cosmetic patch 1 of the present invention is affixed to the above-mentioned damaged skin site, the touch feeling similar to that of surrounding healthy skin can be obtained. By embossing the back surface of the base material layer 11, the touch feeling similar to that of surrounding healthy skin can be further improved during application. By improving the touch feeling, the psychological rehabilitation effect of improving the satisfaction of the subject's heart can be further enhanced.

  The polyurethane elastomer can be molded into the thin base material layer 11 by employing a general film or sheet molding method such as an extrusion molding method, a solution casting method, or a calendar method. A solution casting method in which an organic solvent solution of a polyurethane elastomer is cast on a support to volatilize the organic solvent is a preferable film forming method in that a thin polyurethane elastomer layer having a uniform thickness can be easily formed. When fine irregularities are provided on the surface of the support, the fine irregularities can be transferred to the surface of the formed polyurethane elastomer layer. When a carrier material is used as a support, a cosmetic patch 1 having a carrier layer on the back surface of a support layer made of polyurethane elastomer can be obtained.

  It is preferable that the base material layer 11 has almost no difference (anisotropy) due to the direction of physical properties from the viewpoint of uncomfortable feeling during application (resistance feeling of the cosmetic patch 1 when the skin is stretched). From this viewpoint, as a film forming method, a solution casting method or a calender method in which a difference depending on the direction of physical properties does not appear is preferable, and a solution casting method is more preferable.

  The polyurethane elastomer may contain various additives such as colorants such as pigments and dyes, antioxidants, ultraviolet absorbers, lubricants, fillers, and softeners as desired. The colorant can be used to match the color tone of the cosmetic patch 1 to the skin color, but in order to make the appearance of the damaged skin application site inconspicuous, the colorant is yellow, An orange type or the like is preferable.

  Further, the base material layer 11 made of polyurethane elastomer is excellent in ultraviolet absorptivity, and exhibits an ultraviolet transmittance of 20% or less, preferably 15% or less within the wavelength range when measured in the wavelength range of 280 to 400 nm. . In the wavelength region of 280 to 360 nm, the ultraviolet transmittance is 14% or less. In particular, in the region where the wavelength is 300 nm or less, the ultraviolet transmittance is rapidly reduced to 10% or less. The ultraviolet transmittance was measured using an ultraviolet-visible spectrophotometer (Ubest-V530) manufactured by JASCO Corporation.

  The pressure-sensitive adhesive layer 12 has a thickness of 1 to 15 μm and contains 70 wt.% Of at least one monomer unit selected from the group consisting of an alkyl acrylate ester having a C 8-12 alkyl group and an alkyl methacrylate ester. % Of an acrylic pressure-sensitive adhesive composed of a copolymer contained in a proportion of at least%, and a layer containing cosmetic ingredients.

  The acrylic pressure-sensitive adhesive, which is the main component constituting the pressure-sensitive adhesive layer 12, has the characteristics that, when applied to the skin, it does not easily cause fogging, has a clear feeling, and can easily adjust the pressure-sensitive adhesive properties. Among the monomers, acrylic acid alkyl ester is preferable, and more specifically, for example, 2-ethylhexyl acrylate, isooctyl acrylate, n-octyl acrylate, and isononyl acrylate are more preferable. Moreover, it is more preferable that the acrylic ester copolymer contains the monomer unit in a proportion of 80% by weight or more. In addition, the acrylate copolymer may be a copolymer of one or more monomers, but more preferably a copolymer with another comonomer.

  Examples of other comonomers include monomers having a functional group such as monomers having a carboxyl group such as acrylic acid and methacrylic acid; monomers having a hydroxyl group such as hydroxyethyl acrylate and hydroxypropyl acrylate; As other comonomers, various monomers such as vinyl acetate, styrene, vinyl pyrrolidone, and acrylamide can also be used. Furthermore, an acrylic acid alkyl ester or a methacrylic acid alkyl ester having an alkyl group other than an alkyl group having 8 to 12 carbon atoms, such as ethyl acrylate and butyl acrylate, can also be used as a comonomer.

  As a preferable acrylate ester copolymer, at least one monomer selected from the group consisting of an alkyl acrylate ester having 8 to 12 carbon atoms and an alkyl methacrylate ester, 70 to 95% by weight, and a functional group. A copolymer obtained by copolymerizing 1 to 10% by weight of the comonomer having 0 to 25% by weight of the other comonomer can be exemplified.

  The acrylic pressure-sensitive adhesive uses the monomer component as an initiator in an organic solvent such as toluene, hexane, or ethyl acetate, a peroxide such as benzoyl peroxide, or an azo compound such as AIBN (azobisisobutyronitrile). It can be prepared by solution polymerization in a nitrogen atmosphere. The acrylic pressure-sensitive adhesive can also be prepared by emulsifying and dispersing the monomer component in water with an emulsifier and then emulsion polymerization. A crosslinking agent such as an epoxy resin may be added to the acrylic pressure-sensitive adhesive and crosslinked in the pressure-sensitive adhesive layer forming step.

  The thickness of the pressure-sensitive adhesive layer 12 is 1 to 15 μm, preferably 1 to 12 μm, more preferably 1 to 8 μm, and particularly preferably 1 to 6 μm. The pressure-sensitive adhesive layer 12 has a smaller tensile resistance than the base material layer 11 and high stretchability, and therefore can be set in a wider range than the thickness range of the base material layer 11. However, if the thickness of the pressure-sensitive adhesive layer 12 becomes too large, it tends to be difficult to conform to wrinkles and fine irregularities on the skin, and the attached state is easily noticeable. If the thickness of the pressure-sensitive adhesive layer 12 is too thin, in addition to the tendency that the formation of the uniform pressure-sensitive adhesive layer 12 tends to be difficult, the adhesiveness to the skin tends to be insufficient.

  When the pressure-sensitive adhesive layer 12 is extremely thin, although it is excellent in adaptability to fine unevenness of the skin such as a skin groove which is a minimal groove seen on the skin, the adhesive force to the skin may be reduced. In this invention, the thickness of the base material layer 11 is 1-10 micrometers, the thickness of an adhesive layer is 1-15 micrometers, and the total thickness of the base material layer 11 and the adhesive layer 12 exists in the range of 2-20 micrometers. In the patch 1, the adhesive layer 12 has a 90 ° peeling force of 0.1 N / 10 mm or more against the bakelite plate measured at a speed of 300 ± 30 mm per minute according to JIS Z 0237. As shown, it is preferable to adjust the adhesiveness of the adhesive. This peeling force is a characteristic corresponding to the adhesive force of the pressure-sensitive adhesive layer 12.

  The lower limit of the peeling force (adhesive strength) of 0.1 N / 10 mm described above is not necessarily a large value, but since the base material layer 11 is thin and flexible, the thickness and the peeling force of the base material layer 11 are in an appropriate range. If it satisfies, it is preferable because a sufficient function as the cosmetic patch 1 can be exhibited. The peeling force of the pressure-sensitive adhesive layer 12 is preferably 0.1 to 3 N / 10 mm, more preferably 0.2 to 3 N / 10 mm. If the peeling force (adhesive strength) is too high, it becomes easy for the application portion to be fogged, and it becomes difficult to peel the cosmetic patch 1 from the skin after use.

  Various additives such as colorants such as pigments and dyes can be added to the pressure-sensitive adhesive layer 12 as necessary. The colorant can be used to match the color tone of the cosmetic patch 1 to the skin color, but in order to make the appearance of the damaged skin application site inconspicuous, the colorant is yellow, An orange type or the like is preferable. In addition, for example, an antibacterial agent, a moisturizer, a whitening agent, an anti-wrinkle agent, an anti-sagging agent, an anti-dulling agent, a hair-restoring agent, a beauty nail agent, vitamins, a fragrance, etc. You can also.

  The carrier layer 13 can prevent wrinkles from entering the base material layer 11 and can strengthen the waist of the cosmetic adhesive material 1 to facilitate the application work to the application site. The carrier layer 13 is peeled from the base material layer 11 when the cosmetic patch 1 is applied to the skin. The cosmetic patch 1 provided with the carrier layer 13 can be formed on the base material layer 11 made of polyurethane elastomer by a solution casting method using the carrier layer 13 as a support layer.

  The carrier layer 13 is made of, for example, a film made of various thermoplastic resins such as polyurethane, polyethylene, polypropylene, ionomer, polyamide, polyvinyl chloride, polyvinylidene chloride, ethylene vinyl acetate copolymer, thermoplastic polyester, and polytetrafluoroethylene. It is preferable to form by using. For the purpose of environmental conservation, the carrier layer 13 is made of polyhydroxybutyrate, polyhydroxybutyrate resin, polyhydroxyalkanoate, maltotriose, polylactic acid, polylactic acid resin, polyethylene succinate, polyethylene succinate resin, polybutylene.

  Examples of the method for containing the cosmetic component 15 in the pressure-sensitive adhesive layer 12 include a method of kneading and dispersing the above-described optional cosmetic component 15 in the acrylic pressure-sensitive adhesive that is the main component constituting the pressure-sensitive adhesive layer 12. Can be mentioned. Further, when the cosmetic component 15 is contained in the adhesive layer 12, the surface of the cosmetic component 15 is coated with, for example, a material that dissolves when the cosmetic patch 1 is applied to the skin, and this coating is performed. The cosmetic component 15 may be kneaded or dispersed in the acrylic pressure-sensitive adhesive.

  In addition, as a method for forming minute unevenness on the back surface of the base material layer 11 by embossing, for example, when the method of forming the base material layer 11 on the carrier layer 13 is adopted, the carrier layer 13 is configured. For example, fine irregularities are provided on the surface of the carrier material to be transferred, and the fine irregularities are transferred to the base material layer 11. In order to form fine irregularities on the carrier material, a known embossing method using an embossing roll can be employed. As another method, fine irregularities may be formed by sandblasting the surface of the carrier material or adding a filler to the carrier material.

  On the other hand, in order to form the pressure-sensitive adhesive layer 12 on the separator layer 14, it is preferable to employ a method in which an acrylic pressure-sensitive adhesive solution is applied onto the separator material by a solution casting method and dried.

  Further, the cosmetic patch 1 according to the present invention may contain a cosmetic component 15 in the base material layer 11 as shown in FIG. Also in this case, the cosmetic component 15 can be the same as that contained in the pressure-sensitive adhesive layer 12. In addition, when the cosmetic patch 1 having the constitution in which the cosmetic component 15 is contained in the base material layer 11 is applied to the skin, the cosmetic component 15 passes through the adhesive layer 12 and penetrates into the skin.

  Moreover, the cosmetic patch 1 according to the present invention may contain a cosmetic component 15 in both the base material layer 11 and the pressure-sensitive adhesive layer 12, as shown in FIG. In the case of this configuration, the content ratio of the beauty component with respect to the cosmetic patch 1 can be increased as compared with the case where the beauty component 15 is contained in either the base material layer 11 or the pressure-sensitive adhesive layer 12. Moreover, since the cosmetic ingredient 15 contained in the base material layer 11 penetrates into the skin later than the cosmetic ingredient 15 contained in the adhesive layer 12, the cosmetic ingredient 15 penetrates into the skin further continuously. Can be made.

  Furthermore, in the cosmetic patch 1 according to the present invention, as shown in FIG. 4, a cosmetic component layer 25 containing a cosmetic component 15 is interposed between the base material layer 11 and the adhesive layer 12. May be. In the case of this configuration, the cosmetic component 15 penetrates the skin through the adhesive layer 12 when the cosmetic patch 1 is applied to the skin.

  As shown in FIG. 5, the cosmetic patch 1 having the above-described configuration is applied so as to cover the portion of the skin where the cosmetic component 15 is to be infiltrated, thereby continuing the state where the skin is packed with the cosmetic component 15. Therefore, the cosmetic ingredient 15 can be efficiently penetrated into the skin. In addition to the effect of infiltrating the cosmetic component 15 into the skin, the skin to which the cosmetic patch 1 is applied has, for example, spots, bruises, freckles, pores, scars, acne scars, thermal scars, discoloration due to skin diseases, etc. If you can hide these naturally. Moreover, it can be made the external appearance more similar to the surrounding healthy skin by applying makeup from the applied cosmetic patch 1.

  Further, the cosmetic patch 1 of the present invention is adapted to fine irregularities (fine grooves) on the skin, the sticking part is not conspicuous, can easily follow the movement of the skin, and causes blurring. It is difficult to protect the skin from cosmetics and ultraviolet rays, and the cosmetics can be applied in an applied state. “Adapting to fine unevenness of the skin” means that the cosmetic patch 1 of the present invention enters the fine unevenness of the skin including the skin groove or the like and exhibits the same appearance as the skin. When the back surface of the base material layer is embossed, the cosmetic patch 1 of the present invention causes a slight difference in thickness between the base materials and exhibits more flexibility, so that it can easily enter into skin grooves and wrinkles.

  The cosmetic patch 1 of the present invention has a thin adhesive layer 12 and a base layer 11 that is excellent in water absorption and moisture permeability. Less likely to cause. When applying cosmetics, if water is applied from the back surface of the base material layer 11, the base material layer 11 made of polyurethane elastomer becomes soft and becomes more familiar with the skin surface, and the riding of the cosmetics becomes better. Since the polyurethane elastomer has a low glass transition temperature, it has excellent flexibility at a temperature near body temperature, and is excellent in adaptability to the skin surface, applicability of cosmetics, and the like.

  Furthermore, the cosmetic patch 1 of the present invention, in addition to the effect of permeating the cosmetic component 15 into the skin, stretches out the wrinkles or sagging of the skin, such as the corners of the eyes, the lower part of the eyes, the mouth, and the cheeks, and makes them less noticeable. Can be used. Such a use is also a part of the makeup method using the cosmetic patch 1 of the present invention. When the cosmetic patch 1 is applied with the cosmetic patch 1 of the present invention in a state where the wrinkles or sagging are stretched by stretching the wrinkle or sagging skin part, and the tension is released, the beauty patch 1 It is estimated that the adhesive patch 1 enters a state such as a skin groove or a wrinkle. As a result, the cosmetic patch 1 exists in a state of being folded on the surface of the skin, and the entire appearance looks flat. By such a mechanism, it is presumed that an appearance that reduces wrinkles or sagging can be formed simply by sticking the cosmetic patch 1 to a site with wrinkles or sagging. If water is applied from above the base material layer 11 after sticking, the base material layer 11 swells due to water absorption, so that the effect of extending wrinkles or sagging becomes greater. Since the base material layer 11 made of a polyurethane elastomer has water absorption, even if water is not applied after sticking, it absorbs the water evaporated from the body over time and swells, so that the effect of extending wrinkles or sagging increases. There is expected. The degree of swelling of the base material layer 11 made of this polyurethane elastomer was determined by immersing a polyurethane elastomer having a thickness of 75 μm and a size of 100 mm × 100 mm in water for 24 hours and measuring the length before and after the immersion (incremental length). ) / (100 mm). The degree of swelling is 1 to 20%, preferably 2 to 10%.

  Moreover, the cosmetic patch 1 of the present invention has a feature that it does not give a sense of incongruity during the application following the movement of the skin. This feature is related to the degree of easiness of extension of the cosmetic patch 1. As an index of the ease of elongation, a 10% tensile load corresponding to the tensile resistance of the cosmetic patch 1 can be used.

  Specifically, the cosmetic patch 1 of the present invention is within the range of 0.01 to 1.2 N / cm in both the vertical and horizontal directions when a 10% tensile load is measured according to Japanese Industrial Standard JIS Z 0237. It is preferable to show a tensile load of This tensile load is preferably 0.01 to 1.2 N / cm, more preferably 0.01 to 1.0 N / cm in both the longitudinal and lateral directions, and 0.01 to 0.5 N / cm. More preferably, it is particularly preferably 0.01 to 0.3 N / cm.

  The thickness of the cosmetic patch 1, the thickness of the base material layer 11, and the ease of elongation of the cosmetic patch 1 have a specific relationship in reducing the conspicuousness and discomfort of the cosmetic patch 1 of the present invention. It has been found that this is preferred. For example, if the thickness of the cosmetic patch 1 or the base material layer 11 is large, the followability to the movement of human skin is not sufficient. On the other hand, if the cosmetic patch 1 is easy to stretch, the followability to the movement of the skin is good. Therefore, the cosmetic patch 1 or the base material layer 11 may be somewhat thick. 1 or the thickness of the base material layer 11 and the ease of elongation have a mutual relationship.
