Description

TECHNICAL FIELD The present invention relates to a skin care cosmetic composition, a skin care cosmetic composition, a skin care cosmetic composition, a skin care cosmetic composition, a skin care cosmetic composition,

The present invention relates to a concealer patch for masking defects of the skin and for whitening the skin. The present invention also relates to a concealer patch which combines an ultraviolet absorber and a cosmetic ingredient to realize whitening of the skin itself.

Concealer is a foundation for covering skin troubles, and is a cosmetic product that fixes spots, freckles, dots, acne marks, and dark circles that give unhealthy impressions. Stick type, cream type and liquid type concealers are frequently used.

The concealer contains a lot of pigments in addition to the adhesion and emollient properties, in order to provide a covering force, as compared with a normal foundation. When using the concealer, it is necessary to paint the skin, lotion, and the base in the same manner as the foundation. After applying the skin, apply it as if putting the paints spontaneously, and tap and lightly with the material which does not cause the fiber residue such as the inside of the finger or cotton swab or swab. The use of this concealer is simple at first glance, but it is difficult to get a natural skin feel when you actually do it, and it is often difficult for beginners to work at home. In addition, the conventional concealer functions only to cover spots and freckles, and there is no product that mixes cosmetic ingredients in products and actively smears spots.

Until now, wax, volatile oil and nonvolatile oil (Patent Document 1), titanium coat pigments, metal soap coat pigments and high cover pigments (Patent Document 2), volatile silicone oils, aqueous components, white (Patent Document 3), talc, hiding powder, titanium mica, liquid paper, and solid paper (Patent Document 4) have been reported. Also, there have been proposed any kinds of peptides (Patent Document 5), polyalkene-based supramolecular polymers (Patent Document 6), and film-forming polyhydroxystyrene polymers (Patent Document 7).

Japanese Patent Application Laid-Open No. 2011-162463 Japanese Patent Publication No. 2010-503725 Japanese Patent Application Laid-Open No. 2005-298482 Japanese Patent Laid-Open No. 2000-327532 Japanese Patent Publication No. 2013-508322 Japanese Patent Application Laid-Open No. 2010-120940 Japanese Patent Application Laid-Open No. 2000-229813

A problem to be solved by the present invention is to solve the inconvenience of currently available stick type, cream type or liquid type concealers and to provide a new patch type which can easily hide spots, freckles, acne marks and dark circles Concealer cosmetics. It is another object of the present invention to provide a cosmetic which realizes whitening of the skin by blending an ultraviolet absorber and a cosmetic ingredient in a support film or adhesive of a patch.

The conceal patch according to the present invention, which has been made in order to solve the above problems, is characterized by having a color of skin color on the surface of a transparent or translucent flexible support film and a pressure-sensitive adhesive layer.

That is, the conceal patch according to the present invention has a transparent or translucent flexible support film and a pressure-sensitive adhesive layer laminated on the support film, and has coloration of skin color on at least one surface of the support film.

In the present invention, a cosmetic adhesive agent having a concealer effect is referred to as a conceal patch, and the skin color includes dark skin color, light skin color, and a skin color ranging from white to white.

A feature of the present invention resides in that coloring is performed on the surface of the support film of the conceal patch using a printing technique.

If the color of the concealer patch is uniform and good, it can be produced by mixing a pigment or a pigment into a support film raw material to form a film. However, when it is desired to partially change the skin color, it can not be produced by this method. For example, a conceal patch having a deep skin color at the central portion and a light skin color at the peripheral portion and a skin color gradually tapering from the central portion toward the peripheral portion, i.e., gradation is colored can not be manufactured by this method. Conceal patches with partially changed skin color can be manufactured only after printing the color on the support film as in the present invention.

Accordingly, the method of manufacturing a concealer patch according to the present invention comprises a step of coloring the surface of a transparent or translucent flexible support film using a printing technique, and a step of forming a pressure-sensitive adhesive layer on the support film.

The conceal patch hides the spots and acne on the face by coloring, but it is preferable not to color uniformly. Because the stain, freckles, acne scars and dark circles in the face are local, they can not be masked unless they are darker in color, while the presence of a uniform dark color and conceal patch itself gives an unnatural impression. Therefore, it is preferable to make the center portion have a slightly dark skin color and the peripheral portion to have a soft and natural feeling.

There are various printing methods for preventing the coloration of the surface of the support film from becoming uniform, or for giving a gradation to the coloring. In the present invention, three methods have been tried.

(1) Coloring in a plane. The planar skin coloration refers to the formation of at least one colored area on the surface of the support film. It may be a structure having a substantially planarly uniform colored surface, and the density of the color may be changed depending on the place.

(2) Use a skin color line in a straight line, a curved line, a dashed line, or a broken line.

(3) Use a plurality of dots to change the size or density of the dots.

Naturally, two or three of these three methods can be combined.

When a planar skin coloration is used, it is preferable to change the concentration of the coloration depending on the place. Particularly, it is preferable to darken the color of the center portion, soften the coloration of the peripheral portion, and give a gradation.

If the periphery of the conceal patch is colorless and the bare skin is visible, the presence of the conceal patch can be made less conspicuous.

When a line of skin color is used, two skin color lines can be crossed at right angles. Or three skin color lines can be intersected with each other by shifting them by 60 占 from each other. The number of directions of the skin color lines can be further increased. In this way, a plurality of skin color lines may be formed, and in that case, it is preferable that at least two lines of the plurality of skin color lines cross each other.

Here, the shape of the line may be a straight line, a curved line, a broken line, a broken line, and the like, and is not limited thereto. In addition, when a line of skin color or a skin color line is simply referred to, it includes a straight line, a curve, a dashed line, a broken line, and the like.

In addition, a closing curve such as a circle or an ellipse can be combined. Even if they are concentric with the center, the closing curves can intersect with each other.

The interval or thickness of the skin color line need not be uniform. Further, in order to give a gradation, the coloring of the skin color line may be made dark at the center and soft at the peripheral portion.

Using a combination of lines, a colorless portion can be formed, whereby the bare skin can be seen and the presence of the conceal patch can be made less visible.

When a plurality of dots are used, the effect of gradation can be obtained by changing the size or density of the dots or changing the density of the skin color. For example, the size of at least one of the dots of a plurality of skin colors or the density of the skin color may be different from other dots. Further, a plurality of dots of skin color may be arranged so as to have a region having a relatively high density and a region having a relatively low density.

The shape of the dot may be any shape such as a circle, an ellipse, a square, or a triangle. In addition, the shapes of the dots do not necessarily have to be the same, and the distribution of the dots does not necessarily have to be regular. Further, when a plurality of dots are simply referred to as dots, any dot of any shape such as a circle, an ellipse, a square, or a triangle is to be included.

If a plurality of dots are used, a colorless portion can naturally be formed.

In order to impart a gradation to the skin color of the conceal patch, it is possible to combine skin color lines crossing the skin color (skin color area) in a planar manner. At this time, it is preferable that the skin coloration (skin color area) in a planar shape is made so that the central portion is darkened and the peripheral portion is softened. In addition, when the skin color in the planar coloration (skin color region) is made to be a skin color close to white, it can be made to be invisible as a whole in harmony with the crossing skin color line.

When the skin color of the conceal patch is graded, a planar skin coloration (skin color area) and a plurality of dots can be used.

The surface comprising the pressure sensitive adhesive layer and the side printing the skin color of the support film may be the same surface or other surface of the film. Or the skin color can be printed on both surfaces of the film.

As the flexible transparent or semi-transparent support film, a polyolefin film such as polyethylene or polypropylene, or an ethylene acid ratio copolymer, polyurethane or nylon film can be used. These may be used alone or a plurality of them may be used in combination.

Polyurethane films are most preferred in terms of breathability and flexibility. The thickness is preferably 3 to 100 mu m. If it is less than 3 탆, mechanical strength may be insufficient, which may make it difficult to manufacture or adhere to the skin, and if it is larger than 100 탆, the skin may become excessively thick. More preferably, the thickness is 5 to 20 占 퐉.

When the polyurethane film is bonded, the handling of the polyurethane film becomes much easier during processing and use. The contact film is called a ground, a carrier, or a ground.

As the pressure-sensitive adhesive layer of the conceal patch, an acrylic pressure-sensitive adhesive, a rubber pressure-sensitive adhesive, a urethane pressure-sensitive adhesive, and a silicone pressure-sensitive adhesive can be used. If necessary, a plasticizer such as octyldodecyl lactate or glycerin may be added.

The thickness of the pressure-sensitive adhesive layer is preferably 5 to 100 mu m. If it is thinner than 5 탆, the adhesive strength may be insufficient. If it is thicker than 100 탆, the air permeability may be lowered, which is sometimes inappropriate for long-time adhesion. A more preferable pressure-sensitive adhesive layer thickness is 5 to 30 占 퐉.

The applicability of the conceal patch can be increased by including an ultraviolet absorber, ultraviolet scattering agent, cosmetic ingredient or skin-care agent in the support film and / or adhesive layer of the conceal patch. These may be used alone, or a plurality of them may be used in combination.

Examples of ultraviolet absorbers include organic ultraviolet absorbers such as benzophenone derivatives such as 2-hydroxybenzophenone and 2-hydroxy-4-methoxybenzophenone, p-aminobenzoic acid and derivatives thereof, and acid derivatives such as salicylhomonenetyl, As the scattering agent, ultraviolet scattering agents such as titanium oxide and zinc oxide can be used.

Examples of cosmetic ingredients include vitamin C and derivatives thereof (for example, magnesium L-ascorbyl phosphate, ascorbyl tetrahexyldecanoate, ascorbyl phosphate 3Na palmitate), kojic acid, retinoic acid and its derivatives, hydroquinone , Vitamin A and derivatives thereof, anti-wrinkle components such as alpha ribose, adenosine, and alpha -hydroxy acid. In addition, an anti-inflammatory component such as an acne treatment component such as salicylic acid and glycyrrhetinic acid (salt) can be compounded. As the stabilizer, BHT, vitamin E and derivatives thereof (for example, tocopherol acetate) and the like can be blended.

If the conceal patch is circular, it is easier to use if the diameter is larger than 5mm. It is mainly attached to the face, feet and arms, so it is about 100cm2 even if it is big. The shape of the conceal patch can be various types such as circle, ellipse, rounded rectangle, square, diamond, face,

The skin whitening care cosmetic method according to the present invention is a skin whitening care cosmetic method using a conceal patch constructed according to the present invention, wherein the pressure sensitive adhesive layer contains a cosmetic ingredient and / or a skin use drug.

The skin acne care make-up method according to the present invention is a skin acne care make-up method using a conceal patch constructed according to the present invention, wherein the adhesive layer contains a cosmetic ingredient and / or a skin-use drug.

Since the concealer is a patch type instead of a stick type, a cream type or a liquid type, attachment to the skin is facilitated. It is possible to easily feel the natural skin texture by covering the defects of the skin such as stain and freckle marks easily.

The skin color of the concealer patch is printed on the support film to be pasted on the support film. As a result, it becomes easy to give a gradation to the skin color. As a result, it is difficult to find out that the concealer is used.

As a result of applying the skin color of the conceal patch to the skin printed on the support film and attaching it, a colorless part can be formed and the degree of freedom of the coloring form is increased. As a result, it is possible to express the skin color of the conceal patch using lines or dots that intersect rather than uniform coloring. From the part of the uncolored, the bare skin was reflected, and it became more natural feeling.

1 is a view showing four types of concealer patches which are colored by printing a skin color on one side of a semitransparent film.
Fig. 2 is a view of four kinds of conceal patches in which a skin coloration (skin color area) in a plane is overlapped with a straight skin color line.

Examples of the present invention will be described below, but the present invention is not limited to the examples.

Although all of the embodiments of the present invention use a circular concealer patch, it is clear that the present invention can be similarly applied to other types of patches such as elliptical or quadrilateral.

In addition, the planar coloration, the skin color line, and the skin color dot in the drawing are all printed by the skin color except for the outline (circle), but are expressed in gray in the drawing.

(Example 1)

Four types of concealer patches shown in Fig. 1 were started. In Example 1 shown in Fig. 1 (a), the entire surface is a printed patch, and skin color is printed on the entire surface. Example 2 shown in Fig. 1 (b) is a partial printed patch, and dark skin color is printed at the center portion, but the peripheral portion is colorless. No printing gradation is formed. In Example 3 shown in Fig. 1 (c), a mesh-printed patch is shown, and a group of straight lines intersecting with each other of the skin color is printed in a mesh form. The hue is centered and gradated depending on its surroundings. The example 4 shown in FIG. 1 (d) is a dot-on-a-print patch, and the overall gradation is obtained by pressing the circular dot at the central portion and printing the outline at the peripheral portion. These conceal patches are circular with a diameter of 15 mm.

Their concealer patches include four floors. (1) process paper (OPP having a thickness of 40 占 퐉), (2) urethane support film (thickness 7 占 퐉), (3) pressure-sensitive adhesive layer (HiPAS10 adhesive, Cos Medesee (Thickness: 15 mu m), (4) release paper (weight per unit area: 100 g / m2, coated with silicone). The color of the skin is printed on one side of the urethane support film.

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

Each of the 4 type conceal patches (Figs. 1 (a) to 1 (d)) was applied to the forearm skin of five volunteers, and the "inconspicuous test" was carried out. The test was conducted by attaching 4 concealer patches to 5 volunteers and judging from the distance of 50 cm whether they could be visually recognized.

The entire surface printing patch (a) was clearly recognizable from a distance of 50 cm for all five persons. In the partial printed patch (b), all of the five persons could recognize the attachment region pointed out. In the mesh-printed patch (c) and the dot-printed patch (d), two out of five people could recognize the attachment site pointed to, but the remaining three could not recognize even if the attachment site was pointed out. According to this test, it can be concluded that the printed material in the mesh or dot form is less noticeable than the other two types and is excellent in "inconspicuousness".

(Example 2)

A concealer patch with a planar skin coloration and a straight skin color line was started. The planar skin coloration was concentrated at the center, and gradually colored as the area around it grew. Skin color lines of straight lines were created and compared with those given the gradation and not given.

The following four species started. Although FIG. 2 is drawn in gray, the color of the real is skin color.

Example 5: Planar skin coloration is gradually softened from the center point toward the periphery. There is no change in the color density of the straight skin color line. This example is shown in Fig. 2 (a).

Example 6: Planar skin coloring has a central portion with a uniform concentration of 3 mm in diameter, and the color of the skin color gradually rises from there to the periphery. There is no change in the color density of the straight skin color line. This example is shown in Fig. 2 (b).

Example 7: Planar skin coloring has no central portion with uniform density, and skin color gradually becomes soft from the center toward the periphery. The color of the straight skin color line gradually rises from the center toward the periphery. This example is shown in Fig. 2 (c).

Example 8: A flat white coloration has a central portion with a uniform concentration of 3 mm in diameter, and the white color gradually becomes tangible therefrom toward the periphery. The color of the straight skin color line gradually rises from the center toward the periphery. This example is shown in Fig. 2 (d).

Comparing the four types shown in Fig. 2, it is hard to notice that the linear skin color line gradually becomes soft from the center toward the periphery, and it is difficult to recognize that the conceal patch is attached from a slightly distant distance.

(Example 3)

Based on the basic configuration of the concealer patch of Example 3 of Fig. 1 (c), a functional concealer patch as shown in Table 1 was prepared by including a low-cost component such as an ultraviolet absorber and cosmetic ingredients.

Urethane film (Kosemedia pharmaceutical agent) was used for the support film, and HiPAS10 (Kosemedia pharmaceutical agent) was used for the adhesive agent. The oil component is contained in the support film or the pressure-sensitive adhesive layer as shown in the table, and the compounding amount thereof is expressed as% by weight. These oil components were purchased from Nakaraitek (Kyoto).

The stigma evaluation method was applied to the symptom of three applicants and evaluated by self - report after applying for one week / one day for four weeks. The evaluation is the average score of the following scores.

Score 0 No change at all

Score 7 Completely gone

(Example 4)

A functional concealer patch was prepared by incorporating the same skin coloring as in Example 8 of Fig. 2 (d) and the same adhesive as in Example 1, with a pressure-sensitive adhesive containing a valuable ingredient such as a plasticizer and a cosmetic ingredient as shown in Table 2. The support film was a urethane film having a thickness of 10 탆, and 2% by weight of 2-hydroxybenzophenone was blended.

The evaluation results of the conceal patch were as follows.

1. Ultraviolet Shielding UVA 97.2% Shielding UVB 98.6% Shielding

2. Invisibility In the test results of the three applicants, the patch could not be recognized even if the attachment point was pointed out.
