Description

  The present invention relates to a concealer patch for hiding skin defects and making the skin look white and beautiful. Furthermore, the present invention relates to a concealer patch that combines a UV absorber and a cosmetic ingredient to achieve whitening of the skin itself.

  Concealer is a foundation for covering skin troubles, and is a cosmetic that spot-corrects spots, freckles, moles, acne scars and bears under the eyes that give an unhealthy impression. Stick type, cream type and liquid type concealers are often used.

  Concealer contains a lot of pigment in addition to adhesion and emollient properties than ordinary foundations in order to provide covering power. When using a concealer, it is necessary to prepare a base by plenty of the base and emulsion as well as the foundation. After applying the groundwork, apply the paint as if it is placed on the surface, and tap it gently with a material that does not leave a fiber residue, such as the belly of a finger or a cotton or cotton swab. This concealer usage is simple at first glance, but when you try it, it is difficult to produce a natural skin texture, and it is often difficult for amateurs to do it at home. In addition, conventional concealers function only to hide spots and freckles, and there is no product that also contains beauty ingredients in the product and actively uses whitening such as spots.

  As materials having a concealer effect, wax, volatile oil and non-volatile oil (Patent Document 1), titanium coat pigment, metal soap coat pigment and highly coated pigment (Patent Document 2), volatile silicone oil, aqueous Ingredients, white pigments, glitter powders, etc. (Patent Document 3), talc, concealing powders, titanium mica, liquid fats and solid fats (Patent Document 4) have been reported. In addition, certain types of peptides (Patent Document 5), supramolecular polymers of polyalkene bases (Patent Document 6), film-forming polyhydroxystyrene polymers (Patent Document 7), and the like have been proposed.

  The problem to be solved by the present invention is to eliminate the difficulty of using stick-type, cream-type and liquid-type concealers that are currently on the market, and anyone can easily hide spots, freckles, acne marks, bears, etc. It is to provide a new patch-type concealer cosmetic. Furthermore, it is to provide a cosmetic that achieves whitening of the skin by blending an ultraviolet absorber and a cosmetic ingredient into a support film for the patch and an adhesive.

The concealer patch according to the present invention, which has been made to solve the above-mentioned problems, is characterized by having a skin color coloring on the surface of a transparent or translucent flexible support film and having an adhesive layer.
That is, the concealer patch according to the present invention comprises a transparent or translucent flexible support film, and an adhesive layer laminated on the support film, and the skin color on the surface of at least one side of the support film It is characterized by having the following coloring.

  In the present invention, a cosmetic patch having a concealer effect is referred to as a concealer patch, and the skin color includes a deep skin color to a light skin color, and a skin color close to white to white.

  A feature of the present invention is that the surface of the support film of the concealer patch is colored using a printing technique.

If the color of the concealer patch is uniform, it can be produced by mixing a dye or pigment with the support film raw material to form a film. However, this method cannot be used to partially change the skin color. For example, a concealer patch colored with a dark skin color at the central part and a light skin color at the peripheral part so that the skin color gradually becomes lighter from the central part toward the peripheral part, that is, with a gradation cannot be produced by this method. A concealer patch having a partially changed skin color can be produced only after coloring is printed on a support film as in the present invention.
Therefore, the method for producing a concealer patch according to the present invention includes a step of coloring the surface of a transparent or translucent flexible support film using a printing technique, and forming an adhesive layer on the support film. And a step of performing.

  The concealer patch hides stains and acne on the face by coloring, but it is desirable not to color it uniformly. Face stains, buckwheat, acne scars and bears are local, so they can only be hidden to a certain degree of dark color, but if they are a uniform dark color, the presence of the concealer patch itself gives an unnatural impression. . For this reason, it is desirable that the central portion has a slightly darker skin color and the peripheral portion has a lighter natural texture.

Various printing methods can be conceived in order to make the coloring of the support film surface non-uniform or to give gradation to the coloring. In the present invention, three methods have been tried.
(1) It is colored planarly. Planar skin coloration means that at least one skin color region is provided on the surface of the support film. The structure may have a substantially flat colored surface, and the color density may vary depending on the location.
(2) A straight, curved, wavy or polygonal skin color line is used.
(3) Use a large number of dots and change the size and density of the dots.
Of course, two or three of these three methods may be combined.

When planar skin color coloring is used, it is preferable to change the coloring intensity depending on the location. In particular, it is preferable to darken the central portion, lighten the peripheral portion, and add gradation.
If the peripheral part of the concealer patch is made colorless and can be seen through the background, the presence of the concealer patch can be made even less conspicuous.

When using a flesh-colored line, two flesh-colored lines can intersect at right angles. Alternatively, the three flesh-colored lines may cross each other with a 60 ° shift. The number of skin color line directions may be increased. Thus, a plurality of skin color lines may be provided, and in that case, it is preferable that at least two of the plurality of skin color lines intersect each other.
Here, the shape of the line can be selected from a straight line, a curved line, a wavy line, a broken line, and the like, but is not limited thereto. Note that the term “skin color line” or “skin color line” includes straight lines, curved lines, wavy lines, broken lines, and the like.

  A closed curve such as a circle or an ellipse may be combined. The closed curves may intersect with each other even if they are concentric with the centers.

  The interval and thickness of the flesh color line need not be uniform. In order to add gradation, the skin color line may be darkened at the center and light at the periphery.

  If a combination of lines is used, a colorless portion can be provided, whereby the background can be seen through and the presence of the concealer patch can be made less noticeable.

When a large number of dots are used, a gradation effect can be obtained by changing the size and density of the dots, or changing the darkness of the skin color. For example, the size of at least one dot or the darkness of the flesh color may be different from other dots among the many flesh-colored dots. Further, a large number of flesh-colored dots may be arranged so as to have a relatively high density area and a relatively low density area.
The shape of the dot can be any shape such as a circle, an ellipse, a square, or a triangle. Further, the dot shapes do not necessarily have to be the same, and the dot distribution does not necessarily have to be regular. It should be noted that the term “a large number of dots” includes dots of any shape such as a circle, an ellipse, a square, and a triangle.

  If a large number of dots are used, naturally a colorless portion can be provided.

  In order to add gradation to the skin color of the concealer patch, planar skin color coloring (skin color region) and skin color lines that intersect may be combined. At this time, it is preferable that the flat skin color coloring (skin color region) is dark at the center and thin at the periphery. Further, if the skin color in the planar coloring (skin color region) is a skin color close to white, it can be well balanced with the intersecting skin color lines so as not to stand out as a whole.

  When gradation is applied to the skin color of the concealer patch, planar skin color coloring (skin color region) and a large number of dots may be used.

  The surface on which the skin color of the support film is printed and the surface having the pressure-sensitive adhesive layer may be the same surface or different surfaces of the film. Alternatively, the skin color may be printed on both surfaces of the film.

  As the flexible transparent or translucent support film, a polyolefin film such as polyethylene or polypropylene, or an ethylene vinyl acetate copolymer, polyurethane or nylon film can be used. These may be used alone or in combination.

  A polyurethane film is most preferable from the viewpoints of air permeability and flexibility. The thickness is preferably 3 to 100 μm. If the thickness is smaller than 3 μm, the mechanical strength may be insufficient, which may be inconvenient for manufacturing and sticking to the skin. If the thickness is larger than 100 μm, the thickness may be too thick, and the skin may be uncomfortable. More preferably, the thickness is 5 to 20 μm.

  When the polyurethane film is lined, it becomes even easier to handle during processing and use. The backing film is called process paper, carrier or mount.

  An acrylic adhesive, a rubber adhesive, a urethane adhesive, and a silicon adhesive can be used for the adhesive layer of the concealer patch. If necessary, a plasticizer such as octyl dodecyl lactate or glycerin may be added.

  The thickness of the pressure-sensitive adhesive layer is preferably 5 to 100 μm. If it is thinner than 5 μm, the adhesive strength may be insufficient, and if it is thicker than 100 μm, the air permeability may be lowered and may be inappropriate for sticking for a long time. A more preferable pressure-sensitive adhesive layer thickness is 5 to 30 μm.

The support film and / or the pressure-sensitive adhesive layer of the concealer patch may contain an ultraviolet absorber, an ultraviolet scattering agent, a cosmetic ingredient, or a skin drug, thereby expanding the adaptability of the concealer patch. These may be used alone or in combination.
Examples of ultraviolet absorbers include organic ultraviolet absorbers such as 2-hydroxybenzophenone and benzophenone derivatives such as 2-hydroxy-4-methoxybenzophenone, paraaminobenzoic acid and derivatives thereof, and acid derivatives such as salicylhomonentil, and ultraviolet scattering agents. As such, an ultraviolet scattering agent such as titanium oxide or zinc oxide can be used.
Examples of cosmetic ingredients include vitamin C and derivatives thereof (for example, L-ascorbyl magnesium phosphate, ascorbyl tetrahexyldecanoate, ascorbyl palmitate 3Na), kojic acid, retinoic acid, and derivatives thereof, whitening ingredients such as hydroquinone, Examples thereof include vitamin A and derivatives thereof, and anti-wrinkle components such as α-riboic acid, adenosine, and α-hydroxy acid. Moreover, you may mix | blend anti-inflammatory components, such as acne treatment components, such as a salicylic acid, and glycyrrhetic acid (salt). Further, as a stabilizer, BHT, vitamin E, and derivatives thereof (for example, tocopherol acetate) may be blended.

If the concealer patch is circular, it is easier to use if it is larger than 5 mm in diameter. Since it is mainly applied to the face, legs and arms, it is about 100 cm ² at most. The concealer patch can be formed in various shapes such as a circle, an ellipse, a rectangle with rounded corners, a square, a diamond shape, a face shape, and a ball shape.
The skin whitening care cosmetic method according to the present invention is a skin whitening cosmetic makeup method using a concealer patch constructed according to the present invention, wherein the adhesive layer contains a cosmetic ingredient and / or a skin drug. It is characterized by.
A skin acne care cosmetic method according to the present invention is a skin acne care cosmetic method using a concealer patch constructed according to the present invention, wherein the adhesive layer contains a cosmetic ingredient and / or a skin drug. It is characterized by.

  Since the concealer is a patch type instead of a stick type, cream type or liquid type, it can be easily applied to the skin. Even if you are not an expert, you can easily cover skin defects such as stains and freckles, and feel the natural skin texture.

  As a result of applying the skin color of the concealer patch by printing the skin color on the support film, it became easy to add gradation to the skin color. As a result, using a concealer was difficult to find in appearance.

  As a result of applying the skin color of the concealer patch by printing the skin color on the support film, it was possible to provide a colorless portion, and the degree of freedom of the coloring format increased. As a result, the skin color of the concealer patch can be expressed using intersecting lines and dots instead of uniform coloring. The background is transparent from the uncolored part, and it feels more natural.

FIG. 1 is a diagram of four concealer patches colored by printing skin color on one side of a translucent film. FIG. 2 is a diagram of four types of concealer patches in which planar skin color coloring (skin color region) and linear skin color lines overlap.

Examples of the present invention are shown below, but the present invention is not limited to the examples.
Although all circular concealer patches are used in the embodiments of the present invention, it is obvious that the present invention can be similarly applied to patches of other shapes such as an ellipse and a quadrilateral.
Further, the planar coloring, flesh color lines and flesh color dots in the figure are all printed in flesh color except for the outline (circle), but are represented in gray on the drawing.

Example 1
Four types of concealer patches shown in FIG. Example 1 shown in FIG. 1A is a full surface print patch, and a flesh color is printed on the entire surface. Example 2 shown in FIG. 1B is a partial print patch, in which a dark skin color is printed at the center, but the periphery is colorless. No gradation is provided for printing. Example 3 shown in FIG. 1C is a mesh print patch, and a group of straight lines of flesh colors intersecting each other is printed in a mesh shape. The hue is dark at the center and lighter towards the periphery, with a gradation. Example 4 shown in FIG. 1D is a dot-like print patch, which has an overall gradation by printing circular dots densely in the central part and sparsely in the peripheral part. These concealer patches are circular with a diameter of 15 mm.

These concealer patches consist of four layers. (1) Process paper (40 μm thick OPP), (2) Urethane support film (7 μm thick), (3) Adhesive layer (HiPAS10 adhesive, cosmetics) (Manufactured by Dy Seiyaku Co., Ltd.), thickness 15 μm), and (4) release paper (weight per unit area 100 g / m ² , silicone coating). Skin-colored printing is applied to one side of the urethane support film.

  At the time of use, first, the parts (1) to (3) are peeled off from the release paper (4) and applied to the skin, and then the process paper (1) is peeled off.

  Four kinds of concealer patches (FIGS. 1 (a) to 1 (d)) were applied to the skin of the lower arms of five volunteers, and a “not-conspicuousness test” was performed. In the test, four types of concealer patches were affixed to five volunteers and judged by whether they could be recognized visually from a distance of 50 cm.

  The full-surface printed patch (a) was clearly recognizable from a distance of 50 cm for all five people. The partial print patch (b) could only be recognized when the application site was pointed out for all five people. The mesh-like print patch (c) and the dot-like print patch (d) were not recognized until 2 out of 5 people pointed to the application site, but the remaining 3 people could recognize the application site. I couldn't recognize it. From this test, it can be concluded that what is printed in a mesh or dot form is less conspicuous than the other two types and is excellent in “not noticeable”.

(Example 2)
A concealer patch in which planar skin coloration and straight skin color lines overlap was made. The flat skin coloration was dark at the center and gradually faded toward the periphery. As for the straight skin color line, the one with and without the gradation was created and compared.

The following four types were prototyped. Although FIG. 2 is drawn in gray, the actual color is skin color.
Example 5: In the planar skin color coloring, the skin color gradually becomes thinner from the center point toward the periphery. The straight skin color line does not change the color intensity. An example of this is shown in FIG.
Example 6: The planar skin color coloring has a central portion having a uniform thickness of 3 mm in diameter, and the skin color gradually becomes lighter toward the periphery from there. The straight skin color line does not change the color intensity. An example of this is shown in FIG.
Example 7: In the planar skin color coloring, there is no central portion having a uniform darkness, and the skin color gradually becomes lighter from the center toward the periphery. The color of the straight skin color line becomes gradually lighter from the center toward the periphery. An example of this is shown in FIG.
Example 8: The planar white coloring has a central portion with a uniform thickness of 3 mm in diameter, and the color of the white gradually becomes thinner from there toward the periphery. The color of the straight skin color line becomes gradually lighter from the center toward the periphery. An example of this is shown in FIG.

  Comparing the four types of FIG. 2, the example in which the color of the straight skin color line gradually decreases from the center toward the periphery is less noticeable, and it is visually recognized that a concealer patch is attached from a little distance. Hateful.

(Example 3)
Based on the basic configuration of the concealer patch of Example 3 in FIG. 1 (c), functional concealer patches as shown in Table 1 were prepared by including valuable components such as ultraviolet absorbers and cosmetic ingredients.

  A urethane film (manufactured by Kosmedy Pharmaceutical) was used as the support film, and HiPAS10 (manufactured by Kosmedy Pharmaceutical) was used as the adhesive. As shown in the table, the valuable component is contained in the support film or the pressure-sensitive adhesive layer, and the blending amount is indicated by weight%. These valuable ingredients were purchased from Nacalai Tesque (Kyoto).

  The stain evaluation method was applied to the stains of 3 volunteers, and was evaluated by self-report after application for 1 week / day for 4 weeks. Evaluation is the average score of the following scores.

Score 0 No change at all
Score 7 The stain has disappeared completely

Example 4
Using the same skin color coloring as Example 8 of FIG. 2 (d) and the same adhesive as in Example 1, and containing valuable components such as plasticizers and cosmetic ingredients in the adhesive as shown in Table 2, a functional concealer patch is prepared. Created. The support film was a urethane film having a thickness of 10 μm, and 2% by weight of 2-hydroxybenzophenone was blended therein.

The evaluation results of this concealer patch were as follows.
1. Ultraviolet shielding UVA 97.2% shielding UVB 98.6% shielding Inconspicuousness According to the test results of three volunteers, the patch could not be recognized even if the location of the patch was pointed out.
