Description

The present invention relates to a method for removing sebum present in human nose pores.

  In recent years, when performing point makeup, it is more common to use a hand mirror than to use a dresser. Performing point makeup using a hand mirror often performs makeup at close range, and thus often notices pores more conspicuous than when using a dresser. Therefore, there is a demand for products that make pores inconspicuous. It is generally considered that the main cause of pore conspicuity is a horn plug. In connection with this, the present applicant has previously proposed a peel-off type sheet-shaped pack for removing the square plugs present in the pores (see Patent Document 1). This sheet pack is composed of a film-forming cosmetic and a moisture-permeable substrate. When the surface of the film-forming cosmetic material in this sheet pack is applied to, for example, the nose and peeled off after a lapse of a predetermined time, the square plugs in the pores are removed from the pores accompanying the film-forming cosmetic material and removed. Is done.

  The horn plug is generally considered that sebum present in the pores is solidified by mixing with the fallen horny layer or dust. Therefore, even if only the horn plugs are removed, sebum (hereinafter referred to as “reservoir sebum”) still remains in the pores. A plug will be produced. In order to prevent the occurrence of horn plugs, it is important to remove the stored sebum that is the causative substance.

  As a means for effectively removing the accumulated sebum present in the pores, a suction method performed in an esthetic salon is known. However, even if the stored sebum is removed by this method, the sebum is stored again in about one week. Therefore, it is necessary to remove the stored sebum by this method every about one week. Therefore, this method is extremely complicated and expensive. Further, when performing vacuum suction to increase suction efficiency when performing the suction method, internal bleeding may occur, which may cause purpura. Household aspirators are also on the market, but this has a weaker suction than that of esthetic salons, and therefore cannot effectively aspirate sebum.

  By the way, although it is different from the removal of stored sebum, a non-woven fabric and a net-like sheet laminated and integrated are known as interpersonal wipers (see Patent Document 2). There is also known a personal cleansing article including cellulose fibers including an upper layer and a base layer, and the base layer is latex-coated (see Patent Document 3). According to the document, this article is supposed to function as a keratin removal tool. However, in these documents, no consideration is given to the removal of accumulated sebum present in the pores.

Fig.3 (a) is a top view of another embodiment of the sebum removal sheet | seat in the pore of this invention, FIG.3 (b) is an expanded sectional view.

  The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 shows an embodiment of a sebum removing sheet (hereinafter simply referred to as “sebum removing sheet”) in the pores of the present invention. The sebum removing sheet 10 shown in the figure is for sticking to a human nose. The sebum removing sheet 10 has a two-layer structure. Specifically, the sebum removing sheet 10 is composed of a laminate of a base sheet 20 and a mesh sheet 30. The base material sheet 20 defines the outline of the sebum removing sheet 10. The mesh sheet 30 is laminated on the base sheet 20 so as to cover the entire area of one surface of the base sheet 20. The base material sheet 20 and the mesh sheet 30 are integrally joined by a predetermined joining means. At the position of the mesh in the mesh sheet 30, the surface of the base material sheet 10 is exposed.

  The sebum removing sheet 10 has a generally trapezoidal shape in plan view. The hypotenuse of the trapezoid has a smooth curve. In the upper side of the trapezoid, the central area is depressed in an arc shape downward. On the other hand, at the lower side of the trapezoid, the central region protrudes downward in an arc shape. As shown in FIG. 2, the sebum removing sheet 10 is used by being attached to a human nose. In this case, with the vertical center line of the sebum removing sheet 10 aligned with the back of the nose, the upper side is located on the nasal root side, the lower side is located on the nose tip side, and the left and right side parts are located on each nostril, The sebum removing sheet 10 is pasted. The affixing means will be described later.

  The base material sheet 20 constituting the sebum removing sheet 10 has an action as a support for the mesh sheet 30 and also has an action as a cleaning agent impregnation holding part to be described later. Moreover, it has an effect | action as a holding | maintenance part which hold | maintains the stored sebum and the horn plug removed from the pore. From the viewpoint of exerting these functions, a fiber sheet is used as the base sheet 20 in the present embodiment. The fiber sheet is not particularly limited as long as it is a sheet material composed of a fiber material. For example, a nonwoven fabric, a woven fabric, a knitted fabric or a composite material thereof, or a composite material of these and other sheet materials can be given. From the viewpoint of ease of processing, economic efficiency, availability, etc., it is preferable to use a nonwoven fabric as the fiber sheet.

  When using a nonwoven fabric as a fiber sheet, there is no restriction | limiting in particular in the kind of this nonwoven fabric, What was manufactured by the well-known method can be selected appropriately according to the specific use of a sebum removal sheet, and can be used. For example, a spunlace nonwoven fabric, a meltblown nonwoven fabric, a spunbond nonwoven fabric, an air-through nonwoven fabric, a resin bond nonwoven fabric, a needle punched nonwoven fabric, or the like can be used. A composite of these nonwoven fabrics can also be used. Examples of such composites include spunlace-meltblown nonwoven fabric, spunbond-meltblown nonwoven fabric, spunbond-meltblown-spunbond nonwoven fabric, and spunlace-meltblown-spunlace nonwoven fabric. In particular, a composite nonwoven fabric formed by laminating hydrophilic fibers on one side of a melt-blown nonwoven fabric and laminating hydrophobic fibers on the other side, and entangled them by hydroentanglement etc. This is preferable in terms of ease of removal.

  The kind of fiber constituting the fiber sheet can be appropriately selected and used according to the specific use of the sebum removing sheet and the liquid property of the cleaning liquid impregnated therein. As such fibers, thermoplastic synthetic fibers and natural or semi-natural fibers can be used. Synthetic fibers include polyolefin fibers such as polyethylene and polypropylene, polyester fibers such as polyethylene terephthalate, polyamide fibers, acrylic fibers, polyvinyl acetate, polyvinyl alcohol, polyvinyl butyral, and polyvinyl acetate such as vinyl acetate / vinyl pyrrolidone copolymer. Fibers, polystyrene fibers, fibers obtained by blending two or more of these resins, and multicomponent composite fibers (for example, core-sheath type composite fibers or side-by-side type composite fibers) made of these resins. it can. On the other hand, as natural or semi-natural fibers, cotton, rayon, pulp, hemp, silk, wool or the like can be used. These various fibers can be used alone or in combination of two or more.

  The fibers can be continuous filaments of staple fibers or staple fibers. When staple fibers are used, those having an appropriate length are used depending on the method for producing the nonwoven fabric. For example, when a web is prepared using a card machine and this is hydroentangled, or when a nonwoven fabric is produced by blowing air-through hot air, a staple fiber having a length of about 30 to 70 mm is used. This is preferable from the viewpoint of obtaining a non-woven fabric having a good finish. The thickness of the fiber is one factor that affects the retention of the cleaning agent. From this viewpoint, it is preferable to use a fineness of 0.11 to 11 dtex, particularly 0.22 to 5.5 dtex.

The basis weight of the fiber sheet is one factor that affects the operability of the sebum removing sheet 10 and the strength of the fiber sheet. From this viewpoint, the basis weight of the fiber sheet is preferably 5 to 150 g / m ² , particularly preferably 10 to 80 g / m ² .

  The mesh sheet 30 which is a sheet constituting the sebum removal sheet 10 together with the base material sheet 20 includes a plurality of linear materials extending in one direction and a plurality of linear materials extending in a direction orthogonal thereto at their intersections. They are combined to form a lattice network. The mesh sheet 30 is a part having an action of removing stored sebum when the sebum removing sheet 10 is used. For this purpose, the mesh sheet 30 is made of an elastic material. By constituting the mesh sheet 30 from such a material, the linear material constituting the mesh sheet 30 can push out the stored sebum and square plugs from the pores and remove it as if to remove dirt with a rubber spatula. it can. Details are as follows.

  That is, in the sebum removing sheet 10, the linear material 30 a constituting the mesh sheet 30 disposed on one surface of the base sheet 20 acts as a plurality of convex portions provided on the surface of the base sheet 20. The stored sebum and horn plugs are pushed out from the pores by continuous rubbing or itching of the skin by the plurality of convex portions. Moreover, as will be described later, the base material sheet 20 is impregnated with a sebum-soluble detergent, and the detergent exudes between the convex portions, that is, from the mesh sheet mesh, so as to wet the skin. This facilitates the fluidization of the stored sebum and the softening of the horn plugs and facilitates the extrusion thereof.

  From the viewpoint of efficiently extruding stored sebum and square plugs, the elastic material constituting the mesh sheet preferably has a load at 100% elongation of 0.01 to 1.0 N, preferably 0.05 to 0.6 N. More preferably, it is 0.15-0.3N. This load is measured after immersing the mesh sheet in 5 grams of the cleaning agent for 24 hours or more (left in a room at 30 ° C. and 50% RH) when using a sebum-soluble cleaning agent described later in the present invention. Is done. Hereinafter, this state is referred to as “when the agent is wet”. By using an elastic material exhibiting elasticity in the above-mentioned range, moderate rubber elasticity is exhibited without causing the stickiness peculiar to the elastic material and the resulting resistance. The load during 100% stretching (when a sebum-soluble detergent is used, when the agent is wet) uses a general-purpose tensile tester, the sample length between chucks is 10 mm, and the pulling speed is 100 mm / min. It is measured as a load when stretched (30 ° C., 50% RH). As the test piece, one obtained by cutting one linear material (warp or weft) constituting the mesh sheet into a length of 30 mm is used. At this time, a piece of the linear material that crosses and bonds to the linear material to be measured may remain.

The elastic value of the linear material depends on the elastic modulus and thickness of the linear material. That is, the elastic value increases as the elastic modulus of the linear material increases and the thickness increases. For example, a material having an elastic modulus of 10 ⁵ to 10 ⁷ Pa and having a thickness of about 0.1 to 2 mm is preferably used. In addition, when the affinity with a cleaning agent described later is high, the linear material may swell and the elastic value may decrease, so the type and thickness of the linear material are adjusted as appropriate.

  From the viewpoint of efficiently extruding stored sebum and square plugs, it is preferable to control the height of the linear material 30a constituting the mesh sheet, that is, the convex portion. The height of the convex portion, that is, the thickness of the linear material is preferably 100 to 2000 μm, particularly preferably 200 to 1000 μm. The linear material constituting the mesh sheet may have different warp and weft diameters. In this case, at least one of the warp and weft may be in the range of the elastic value. The thickness of the linear material can be measured by microscopic observation.

  The ratio of the area occupied by the convex portion to the area of the base material sheet 20, that is, the ratio of the area occupied by the linear material 30 a of the mesh sheet 30 (hereinafter, this ratio is referred to as “convex portion area ratio”) is stored sebum. And a factor that affects the efficiency of extrusion of the square plug. If the convex area is too small, the pushing action of the stored sebum and square plug tends to be small. Conversely, if the convex area is too large, the resistance due to the convex part increases and the stored sebum and square plug are still There is a tendency for the extrusion action of to become smaller. Further, the convex part area ratio also contributes to the influence of the cleaning agent that exudes from the base sheet 20 exposed between the convex parts. From these viewpoints, the convex portion area ratio is preferably 10 to 90%, particularly preferably 30 to 75%.

  The entire mesh sheet 30 may be bonded to the base sheet 20 or may be partially bonded to the base sheet 20. The feeling of use of the sebum removing sheet 10 can be controlled by adjusting the degree of joining of the mesh sheet 30 and the base sheet 20. That is, a stronger push feeling can be obtained by increasing the area to be joined. On the other hand, a soft feeling of use can be obtained by reducing the number of joint points. In order to join the entire mesh sheet 30 to the base sheet 20, for example, an adhesive such as hot melt is sprayed on the linear material constituting the mesh sheet 30, and then the mesh sheet 30 and the base sheet 20 are pasted. You just need to match. On the other hand, in order to partially join the mesh sheet 30 to the base sheet 20, for example, in addition to the application of the adhesive such as hot melt described above, means such as thermal bonding, ultrasonic bonding, and mechanical thermal bonding are used. Adopt it. In addition, when the mesh sheet 30 is partially bonded to the base material sheet 20, the bonding site may be random or regular. In the case where the joining sites are formed partially and regularly, the joining can be performed so that the belt-like joining sites and the belt-like non-joining sites are alternately positioned with a predetermined width.

As an elastic material constituting the mesh sheet 30, for example, a thermoplastic elastomer can be used. Examples thereof include styrene elastomers such as SBS, SIS, SEBS, and SEPS, olefin elastomers such as ethylene propylene rubber, polyester elastomers, and polyurethane elastomers. In addition, natural rubber, synthetic rubber (polybutadiene, nitrile type, chloroprene type), acrylic rubber, epichlorohydrin rubber, silicone rubber, styrene butadiene rubber, fluorine rubber, or the like can be used as the elastic material.
In particular, SBS, SIS, SEBS, SEPS, ethylene propylene rubber, and polyurethane elastomer are preferably used.

  The base material sheet 20 in the sebum removing sheet 10 is preferably impregnated with a sebum-soluble detergent. Accordingly, when the sebum removing sheet 10 is used, the skin is wetted by the cleaning agent, and the stored sebum and the square plugs are easily pushed out of the pores. From this viewpoint, the sebum-soluble cleaning agent preferably contains at least one of an oil agent, a surfactant, or polyols. This is because these substances promote easy fluidization of stored sebum and softening of horn plugs.

  The oil agent is preferably liquid at room temperature and has a viscosity of 15 mPa · s or less at 30 ° C., for example, hydrocarbon oil such as liquid paraffin, liquid isoparaffin, squalane, isododecane, isopropyl myristate, isononyl isononanoate, apple Acid diisostearyl, neopentyl glycol dicaprate, diacylglycerol, ester oil such as sunflower oil and olive oil, silicone oil having a molecular weight of 300 or less, and the like can be used. In particular, it is preferable to use a volatile oil as the oil agent has a high familiarity with the square plug clogged in the pores, and the solubility of the dirt becomes high. Examples of such volatile oils include light liquid isoparaffin, decamethylcyclopentasiloxane, polydimethylsiloxane (2CS) and the like.

  The amount of the oil used is preferably 1 to 40% by mass, more preferably 5 to 30% by mass, and still more preferably 10 to 15% by mass in the sebum-soluble detergent.

As the surfactant, any of nonionic, anionic, cationic and amphoteric ones can be used, but nonionic ones are preferred. For example, monolauric acid polyethylene glycol, sucrose fatty acid ester, polyglycerin fatty acid ester, polyoxyethylene hydrogenated castor oil, dipentaerythritol fatty acid ester, alkyl polyglucoside and the like can be used.

  The amount of the surfactant used is preferably 1 to 50% by mass, more preferably 2 to 40% by mass, and still more preferably 3 to 30% by mass in the sebum-soluble detergent.

Examples of polyols that can be used include glycerin, 1,3 butylene glycol, isoprene glycol, propylene glycol, dipropylene glycol, erythritol, sorbitol, and the like.

  The amount of the polyol used is preferably 1 to 70% by mass, more preferably 10 to 60% by mass, and still more preferably 20 to 60% by mass in the sebum-soluble detergent.

  It is preferable that the sebum-soluble cleaning agent has appropriate adhesiveness from the viewpoint of easily attaching the sebum removing sheet 10 to the skin. In order to impart adhesiveness, polysaccharides such as hydroxyethyl cellulose and xanthan gum, carboxyvinyl polymers, synthetic polymers such as alkyl acrylate methacrylate copolymers, liquid crystal structures with nonionic surfactants, synthetic hectorites, etc. Clay minerals are used.

  Sebum-soluble detergents include aqueous solvents such as ethanol and diethylene glycol monoethyl ether; moisturizers such as amino acids and urea; hydroxy acids such as salicylic acid, glycolic acid, lactic acid, citric acid and malic acid; BHT, tocopherol and ascorbine Antioxidants such as acids; components usually used in cosmetics such as anti-inflammatory agents, astringents, antibacterial agents, extracts, and perfumes can be included.

  A particularly preferable composition of the sebum-soluble cleaning agent is a composition containing 10 to 40% by mass of an oil agent, 3 to 50% by mass of a surfactant, and 10 to 60% by mass of a polyol.

  The sebum-soluble cleaning agent is preferably impregnated and held 1 to 25 times, particularly 2 to 18 times the dry mass of the base sheet 20. If it is in this range, a sufficient amount of the cleaning agent can be applied to the skin, and when the sebum removing sheet 10 is applied to the skin, the hands are not excessively wetted by the cleaning agent.

  The sebum removing sheet and the sebum-soluble cleaning agent can be supplied as a kit comprising separate parts that are impregnated and used at the time of use. By setting it as a kit, the quantity of the cleaning agent made to impregnate a sebum removal sheet can be adjusted suitably. Moreover, since it becomes easy to package each part to a dry state by setting it as a kit, packing can be simplified.

  When the sebum removing sheet 10 is used, first, the surface of the sheet 10 on which the convex portions are provided, that is, the surface of the mesh sheet 30 is brought into contact with the skin to obtain the state shown in FIG. When the base material sheet 20 in the sebum removing sheet 10 is impregnated with a sebum-soluble detergent, the detergent is applied to the skin through the mesh of the mesh sheet 30. The sebum removing sheet 10 sticks to the skin and the skin is moistened by the cleaning agent. When the base material sheet 20 is not impregnated with a sebum-soluble cleaning agent, the cleaning agent is separately prepared and applied to the surface of the mesh sheet 30 in the skin and / or the sebum removing sheet 10. Then, the sebum removing sheet 10 is pasted on the skin.

When the sebum removing sheet 10 is brought into contact with the skin, it is preferable that a part or all of the part is heated. A preferred temperature is 35 to 42 ° C. As a heating method, bathing, a steam type facial device, a steam towel, heat generation due to hydration of inorganic powder or polyols, heat generation due to oxidation of iron powder or the like can be used.

  When the skin is sufficiently moistened by the cleaning agent (for example, after 1 to 10 minutes), as shown in FIG. 2B, the skin is removed by a finger through the sheet 20 from the base material sheet 20 side in the sebum removing sheet 10. A massage operation is performed to push out and remove the accumulated sebum and horn plugs in the pores. This operation includes not only a narrow sense of itch but also a general massage operation that pushes out stored sebum and horn plugs in pores, including a rubbing operation and the like. The extruded sebum is solubilized in the liquid layer. Finally, wipe out or rinse away the extruded sebum. The square plug is entangled with the base material sheet 20 exposed in the mesh of the mesh sheet 30. From the viewpoint of further softening the horn plug and further improving the fluidity of the stored sebum, it is effective to use the sebum removing sheet 10 during bathing. By the above operation, the stored sebum and square plugs are removed from the pores. The stratum corneum of the skin is also removed by the action of the mesh sheet 30. As a result, when the sebum removing sheet 10 is used, pores are less noticeable without damaging the skin. In addition, the skin feels smooth. When the skin becomes smooth, there is also an additional effect that the makeup paste becomes better when makeup is subsequently performed.

  The sebum removing sheet 10 may be applied not only to the nose as shown in FIG. 2 (a) but also to other parts of the human body. For example, the present invention may be applied to the forehead and chin, which are parts of the face where the secretion of sebum is anxious.

  FIG. 3 shows a sebum removal sheet 10 according to another embodiment of the present invention. The sebum removing sheet 10 shown in the figure has a plurality of convex portions 31 arranged by pattern printing over the entire area instead of using the mesh sheet 30 as convex portions formed on one surface of the substrate sheet 20. . The arrangement pattern of the convex portions 31 may be regular or irregular. The height of the convex portion 31 and the area ratio occupied by the convex portion 31 can be the same as those in the above-described embodiment. The area ratio of each convex portion 31 in plan view is preferably 10 to 90%, and particularly preferably 20 to 40% from the viewpoint that the stored sebum and square plugs can be efficiently extruded.

  The sebum removal sheet 10 of the embodiment shown in FIG. 3 is formed by, for example, pattern-printing a thermal adhesive resin (hot melt) such as EVA in a dot shape on one surface of the base material sheet 20 and heat-sealing it. It can be manufactured by forming 31.

The hot melt adhesion pattern is not particularly limited, but can be formed in a dot shape, a stripe shape, a wave shape, or the like. On the arc, the concentric pattern is excellent in extruding stored sebum. By arranging this pattern at a site with a large amount of sebaceous glands such as the right and left nasal wings and nasal tips, the stored sebum can be effectively removed.

  The size of the convex portion when the convex portion is formed by attaching the elastomer to the sheet is 0.1 to 2 mm, preferably 0.2 to 1 mm in both height and width. The cross-sectional shape of the convex portion is preferably an arc shape, a triangular shape, a trapezoidal shape, or a mountain shape having a depression at the center.

  The elasticity of the convex portion when the convex portion is formed by attaching the elastomer to the sheet is preferably about 105 to 107 Pa.

  As mentioned above, although this invention was demonstrated based on the preferable embodiment, this invention is not restrict | limited to the said embodiment. For example, the mesh sheet 30 in the embodiment shown in FIG. 1 has a rectangular mesh, but a mesh sheet having a circular, trapezoidal, rhombus, hexagonal or other mesh can be used instead. Further, an elastic sheet having an irregularly shaped mesh formed by randomly depositing a plurality of linear materials can also be used. Similarly, in the embodiment shown in FIG. 3, the shape of the convex portion 31 in a plan view is circular, but instead of this, the shape of a polygon, an ellipse, a star, or any combination thereof is used. A convex portion made of may be used.

  Further, when the base material sheet 20 is impregnated with a cleaning agent, the outer surface of the base material sheet 20 should be liquid-free to prevent the hands from getting wet with the cleaning agent when the sebum removing sheet 10 is used. A permeable sheet may be laminated.

  Hereinafter, the present invention will be described in more detail with reference to examples. However, the scope of the present invention is not limited to such examples. Unless otherwise specified, “%” means “mass%”.

(5) Evaluation Using the obtained sebum removal sheet 10, the degree of removal of the stored sebum in the pores of the nose was evaluated by the following method. Thirty men were subjects, and 40 ° C. steam was sprayed on the subject's nose for 30 minutes. Steam spray simulates the bathing condition. Next, the sebum removing sheet 10 was attached only to the left nose wing of the subject. The right nose wing was left as a control. After 5 minutes from pasting, the left nose wing was massaged for 30 seconds through the sebum removal sheet 10 and massaged. Next, the sebum removing sheet 10 was peeled off, and the entire face was washed with Biore face washing foam (manufactured by Kao Corporation). Using a professional aspirator for esthetic salons (suction with a glass esthetic suction tube with an outer diameter of 12 mm and an inner diameter of 9.4 mm), the stored sebum in the pores of the left and right nose wings was sucked and the amount of suction was measured. . Two weeks after this measurement, the same measurement was performed on the same subject. However, the sebum removing sheet 10 was applied only to the right nose wing, and the left nose wing was used as a control. In this way, N = 2 data was collected when the sebum removal sheet 10 was used and when it was not used, and these were arithmetically averaged to calculate the suction amount of the stored sebum. As a result, when the sebum removing sheet 10 was not used (control), the suction amount of the stored sebum was 2.9 mg. On the other hand, when the sebum removing sheet 10 was used (the present invention), the amount of stored sebum sucked was only 1.1 mg, and it was found that 1.8 mg of stored sebum was removed by using the sebum removing sheet 10. . Moreover, when the state of the nose wing after use was visually observed, the conspicuous pores in the nose wing on the side where the sebum removing sheet 10 was used were not observed. Moreover, damage such as red spots was not observed. The skin after use of the sebum removing sheet 10 was slippery.
