Description

  The present invention relates to a cosmetic sheet, and more particularly to a cosmetic sheet used for removing a square plug or the like.

  2. Description of the Related Art In recent years, a cosmetic sheet suitable for removing skin horn plugs is known in which a skin patch layer is formed using a water-soluble polymer on one side of a base material layer made of a nonwoven fabric or the like. This cosmetic sheet is usually applied after a part to be applied such as a nose is previously wetted with water. The applied cosmetic sheet is left in this state for about 10 minutes, and after the moisture has evaporated, it is slowly peeled off. Through such a series of operations, the skin patch layer dissolved or moistened with water comes into contact with the horn plug present in the pores, and then is dried to be integrated with the horn plug, so the skin patch layer is peeled off. By doing so, the square plug can also be removed.

  By the way, since the cosmetic sheet is already dried and peeled off from the skin while adhering to or sticking to the skin, it causes considerable pain to the skin at the time of peeling. Japanese Patent Application Laid-Open No. 5-221443 discloses a sheet using a polymer compound having a salt-forming group and an oil agent as one component of a pack agent, as it can remove horn plugs and the like without causing pain to the skin. Although the pack is disclosed, since the oil agent is used in combination, the ability to remove horn plugs may be reduced. On the other hand, Japanese Patent Application Laid-Open No. 11-199435 discloses a pack cosmetic that can alleviate the pain when peeling from the skin without reducing the ability of the pack to remove horn plugs. This pack cosmetic was selected from the group consisting of analgesics, antipruritics, nonionic surfactants having a polyoxyalkylene chain, alkylene glycol or salicylic acid ester of polyalkylene glycol, and a condensation product of higher fatty acid and amino alcohol. Contains one or more components.

  However, this pack cosmetic still does not have a sufficient ability to remove horn plugs, and cannot meet the high needs of users.

Japanese Patent Application Laid-Open No. 5-221843 JP-A-11-199435

  The inventors of the present invention have developed a technique for improving the ability to remove a square plug from a cosmetic sheet. In the course of the research, by including polyoxyethylene sorbitan fatty acid ester in the skin patch layer, it is possible to remove horn plugs without causing pain to the skin, and to exhibit excellent horn plug removal ability. I found it.

  However, it has been found that when the skin patch layer contains polyoxyethylene sorbitan fatty acid ester, a layer of polyoxyethylene sorbitan fatty acid ester may be formed on the surface of the skin patch layer. In this way, in the cosmetic sheet in which the layer of the polyoxyethylene sorbitan fatty acid ester is formed on the surface of the skin adhesive layer, even if the surface of the skin adhesive layer is covered with a normal release-treated separator, In some cases, light separation of the separator may occur, and in the cutting process for producing a decorative sheet cut into an arbitrary shape, a product defect may occur due to separation or separation of the separator.

  Therefore, there has been a demand for a cosmetic sheet that does not cause light peeling even when a separator is laminated on a skin patch layer in which a layer of polyoxyethylene sorbitan fatty acid ester is formed on the surface of the skin patch layer.

  The present invention has been made in view of the above problems, and the object of the present invention is superior in the ability to remove horn plugs from conventional products, and a layer of polyoxyethylene sorbitan fatty acid ester on the surface of the skin patch layer. An object of the present invention is to provide a cosmetic sheet in which light peeling does not occur even when a separator is laminated on a skin patch layer on which is formed.

  The cosmetic sheet of the present invention has a skin patch layer formed using a wet adhesive composition containing a water-soluble polymer, a polyoxyethylene sorbitan fatty acid ester, and an inorganic filler on one surface of a substrate. The polyoxyethylene sorbitan fatty acid ester is present in a layered manner on the surface of the skin adhesive layer, and has a sheet not subjected to a release treatment as a separator on the surface of the skin adhesive layer. .

  Here, the sheet that has not been subjected to the peeling treatment may be at least one selected from the group consisting of a plastic film and paper.

  In addition, the plastic film can be formed using at least one selected from the group consisting of polyethylene, polypropylene, and polyester.

  In the present invention, the inorganic filler is at least one selected from the group consisting of silica, titanium oxide, titanium black, medicinal charcoal, black iron oxide, alumina, aluminum hydroxide, magnesium hydroxide, and calcium carbonate. It is preferable.

  The water-soluble polymer may be at least one selected from the group consisting of polyvinylpyrrolidone and vinylpyrrolidone-vinyl acetate copolymer.

  The fatty acid forming the polyoxyethylene sorbitan fatty acid ester may be one selected from the group consisting of lauric acid, palmitic acid, stearic acid, and oleic acid.

  The polyoxysorbitan fatty acid ester may have an HLB of 12 or more.

  The water-soluble polymer may contain a water-soluble polymer having a weight average molecular weight of less than 700,000 and a water-soluble polymer having a weight average molecular weight of 700,000 or more.

The wet pressure-sensitive adhesive composition can further contain a moisturizing component.
Here, the moisturizing component may be glycerin and / or a polyhydric alcohol.

  According to the present invention, pain at the time of peeling from the skin can be alleviated, the ability to remove horn plugs from the skin is superior to conventional products, and the surface of the skin patch layer is polyoxyethylene sorbitan fatty acid It is possible to provide a cosmetic sheet in which light peeling does not occur even when a separator is laminated on a skin patch layer in which an ester layer is formed.

BEST MODE FOR CARRYING OUT THE INVENTION

  The cosmetic sheet of the present invention has a skin adhesive layer and a separator on one side of a base material, and the skin adhesive layer contains a water-soluble polymer, polyoxyethylene sorbitan fatty acid ester, and an inorganic filler. It is formed using an adhesive composition, and a polyoxyethylene sorbitan fatty acid ester layer is formed on the surface.

  Here, the polyoxyethylene sorbitan fatty acid ester is preferably blended in the range of 3 to 40 parts by weight with respect to 100 parts by weight of the water-soluble polymer, and preferably 5 to 20 parts by weight. More preferably, it is blended in the range of about 10 parts by mass. If the blending amount of the polyoxyethylene sorbitan fatty acid ester is 3 parts by weight or more, the ability to remove horn plugs can be sufficiently exhibited. Moreover, when the compounding amount of the polyoxyethylene sorbitan fatty acid ester is less than 3 parts by weight, the separator that has not been subjected to the peeling treatment may cause heavy peeling.

  The polyoxyethylene sorbitan fatty acid ester is a nonionic surfactant made of a higher fatty acid ester of sorbit, and is preferably an oil-in-water type (o / w type) in which oil is emulsified in water. Moreover, although there is HLB (Hydrophile Lipophile Balance) as a numerical value showing the correlation between the hydrophilic group and the lipophilic group in the surfactant molecule, the HLB is preferably 12 or more, and the upper limit is 20 or less. It is preferable that it is 14-17, and it is especially preferable that it is 15-17. The polyoxyethylene sorbitan fatty acid ester used in the present invention has high compatibility with sebum components such as cholesterol and waste products attached to the scalp and pores of the human body.

  Preferred examples of the fatty acid in the polyoxyethylene sorbitan fatty acid ester used in the present invention include lauric acid, palmitic acid, stearic acid, and oleic acid. In addition, the polyoxyethylene sorbitan fatty acid ester preferably has an added mole number of ethylene oxide (EO) forming a hydrophilic portion of, for example, 4 mol to 20 mol.

  The water-soluble polymer used in the present invention exhibits adhesiveness due to the presence of water or a hydrophilic medium. Preferred examples of the water-soluble polymer suitable for removing horn plugs include at least one selected from the group consisting of polyvinyl pyrrolidone and vinyl pyrrolidone-vinyl acetate copolymers. If the molecular weight of the water-soluble polymer is too large, the skin adhesive layer formed using the wet adhesive composition may not have sufficient adhesive force due to the presence of water or a hydrophilic medium, and the molecular weight is small. If it passes, the mechanical strength of the skin patch layer may be reduced, and after sticking, a part of the skin patch layer may remain as a residue when peeling and removing the dried cosmetic sheet from the sticking site. These water-soluble polymers preferably have a weight average molecular weight of 5,000 to 5,000,000, and more preferably 20,000 to 1,200,000.

  From the viewpoint of shortening the drying time for evaporating water used for exerting adhesiveness and making it possible to further relieve pain at the time of peeling, a low molecular weight water-soluble polymer, that is, A water-soluble polymer having a weight average molecular weight of less than 700,000, preferably 5,000 to 300,000, and a water-soluble polymer having a high molecular weight, that is, a water-soluble polymer having a weight average molecular weight of 700,000 or more, preferably 1,000,000 to 5,000,000. It is more preferable to use a mixture with a polymer. When a high molecular weight water-soluble polymer and a low molecular weight water-soluble polymer are mixed and used, the blending ratio is preferably appropriately determined according to the molecular weight of the water-soluble polymer used, the purpose of use, etc. For example, the ratio of the high molecular weight water-soluble polymer to the low molecular weight water-soluble polymer is preferably about 5:95 to 95: 5, more preferably 20:80 to 70, by weight. : 30. From the viewpoint of removal efficiency of horn plugs, reduction of pain given to the skin when peeling, etc., for example, polyvinyl pyrrolidone having a weight average molecular weight of 1,200,000 and polyvinyl pyrrolidone having a weight average molecular weight of 450,000 in a weight ratio of 30:70 to It is preferable to use together within the range of 60:40, and it is still more preferable to use together at 40: 60-50: 50.

  Examples of the inorganic filler constituting the wet adhesive composition according to the present invention include silica (particularly anhydrous silicic acid), titanium oxide, titanium black, medicinal charcoal, black iron oxide, alumina, aluminum hydroxide, magnesium hydroxide, Examples thereof include calcium carbonate. These inorganic fillers may be used alone or in combination of two or more. In general, the filler used in the present invention is preferably in a powder state, and its shape is not particularly limited, but it is preferably spherical in view of obtaining uniform dispersibility. Moreover, it is preferable that the average particle diameter is 0.01-50 micrometers, and it is especially preferable that it is 0.1-10 micrometers.

  By including an inorganic filler in the wet pressure-sensitive adhesive composition, the mechanical strength after the formed skin patch layer is wetted and dried can be improved. Moreover, the time required for drying required for drying after sticking can be shortened by containing an inorganic filler. Therefore, if an inorganic filler is contained, even if the thickness of the adhesive layer is thick, it does not take a long time like a conventional product. The reason why the time required for drying is shortened is presumed that the interface between the inorganic filler, the water-soluble polymer and the liquid plasticizer functions as a passage for moisture dissipation.

  The inorganic filler is preferably used within a range of 10 to 200 parts by weight and more preferably within a range of 25 to 100 parts by weight with respect to 100 parts by weight of the water-soluble polymer. If the amount of the filler used is in the range of 10 to 200 parts by weight, the formed skin patch layer will not be flexible enough to fit well at the patch site, and will need to be dried. The time is not prolonged, and the effect of improving the mechanical strength after the skin patch layer is pasted and dried can be obtained.

  In the present invention, two or more kinds of inorganic fillers such as silica, alumina, aluminum hydroxide, titanium oxide, titanium black and medicinal charcoal can be selected, and a part thereof can be blended as a pigment. The amount of the inorganic filler compounded as a pigment is preferably 1 to 20 parts by weight, preferably 3 to 10 parts by weight, based on 100 parts by weight of the water-soluble polymer. Is more preferable. If the usage-amount of the inorganic filler as a pigment exists in the range of 1-20 weight part, the skin sticking layer which shows favorable white or black can be formed.

  A moisturizing component can be blended in the wet pressure-sensitive adhesive composition according to the present invention. As the moisturizing component used in the present invention, a material which is compatible with a water-soluble polymer and dissolves to exhibit a plasticizing effect is used. For example, ethylene glycol, diethylene glycol, triethylene glycol, hexamethylene glycol, other polyethylene glycols, propylene glycol, dipropylene glycol, other polypropylene glycols, glycerol, diglycerol, other polyglycerols, 1,3-butylene Examples include butylene glycols such as glycol and 1,4-butylene glycol, sugar alcohols such as sorbitol and mannitol, glycerides such as lanolin, lecithin, and olive oil. These may use only 1 type or may use 2 or more types together.

  If the amount of the moisturizing component used is excessive, the mechanical strength of the formed skin patch layer after wetting and drying tends to be poor, and if it is too small, the flexibility is poor and the adhesive site is good. It tends to be difficult to fit. Therefore, the moisturizing component is preferably used in the range of 1 to 75 parts by weight, more preferably in the range of 5 to 50 parts by weight with respect to 100 parts by weight of the water-soluble polymer.

  The wet pressure-sensitive adhesive composition according to the present invention is a cosmetic, a fragrance, a preservative, a colorant, an alcohol, a drug, an ultraviolet absorber, or other drugs or additives usually used in cosmetic sheets, if necessary. An agent may be included within a range that does not inhibit the effects of the present invention.

  A wet adhesive composition containing a water-soluble polymer, a polyoxyethylene sorbitan fatty acid ester, an inorganic filler, and a moisturizing component, if necessary, is a hydrophilic medium such as ethyl alcohol or methyl alcohol, water, etc. In addition, after the coating liquid is prepared, it is applied and dried on a release sheet that has been subjected to a release treatment, or on a substrate to form a sheet-like skin patch layer.

  In the present invention, the thickness of the skin patch layer is preferably 10 μm or more and 500 μm or less, and more preferably 50 μm or more and 250 μm or less.

  The cosmetic sheet of the present invention has a layer of polyoxyethylene sorbitan fatty acid ester on the surface of the skin patch layer. The type and amount of water-soluble polymer constituting the wet adhesive composition, polyoxyethylene A polyoxyethylene sorbitan fatty acid ester layer can be formed on the surface of the skin patch layer by appropriately adjusting the blending amount of the ethylene sorbitan fatty acid ester and the type and blending amount of the inorganic filler.

  The cosmetic sheet of the present invention has a skin patch layer on one side of the substrate. Here, as a base material, it is preferable to use a moisture-permeable base material with moisture permeability from a viewpoint of the drying rate of a skin patch layer. Examples of the structure include aggregates of fibers such as woven fabric, non-woven fabric, knitted fabric, and paper, and films such as a porous film and a gas permeable film. Among these, those having an appropriate stretchability that is easily adapted to the curved surface of the pasting site are particularly preferable. Examples of materials include synthetic or natural organic polymers such as nylon, polyester, polyethylene, polypropylene, polyurethane, and cellulose.

  In the present invention, the thickness of the substrate is preferably 10 μm to 200 μm.

  The cosmetic sheet of the present invention has a separator on the skin patch layer. However, as this separator, it is necessary to use a sheet whose surface is not peeled. That is, the separator used in the present invention needs to be a sheet that has not been surface-treated with a polymer such as silicon. Examples of such a sheet include a plastic film and paper whose surface is not peeled.

  Moreover, as a material which forms this plastic sheet, although polyethylene, a polypropylene, polyester etc. are mentioned, for example, polyethylene is used preferably. In the present invention, two or more kinds of materials may be used in combination to form a plastic sheet, and the plastic sheet may be a laminate of two or more layers, or may be a laminate of paper and a plastic sheet. .

  In the cosmetic sheet of the present invention, for example, a coating liquid in which a wet adhesive composition is dispersed in water or the like is applied to one side of a sheet (separator) that has not been subjected to a release treatment, and a substrate is stacked thereon. It can be formed by drying. This cosmetic sheet has a configuration of base material / skin patch / separator, and is cut into an arbitrary shape. The separator can protect the skin adhesive layer from the hygiene aspect or the sticking force until it is peeled off during use. Moreover, by having a separator, there is also an advantage that the decorative sheets can be stacked and stored in a sheet form.

  The cosmetic sheet of the present invention may be packaged with a packaging material such as a moisture-impermeable base material in order to prevent the evaporation of moisture in the cosmetic sheet. For example, it may be stored and hermetically stored in a bag made of a moisture-impermeable substrate.

  As the impermeable base material used in the present invention, for example, a metal foil such as aluminum is preferably used. Moreover, the laminated body of a plastic film and metal foil may be sufficient, for example, the laminated body of aluminum and a polyester film etc. are used preferably.

  Since the cosmetic sheet of the present invention contains the polyoxyethylene sorbitan fatty acid ester which is a nonionic surfactant in the skin patch layer, it can relieve pain when peeling from the skin, and a square plug Can be sufficiently removed.

  In addition, since the cosmetic sheet of the present invention has a polyoxyethylene sorbitan fatty acid ester layer on the surface of the skin patch layer, when the cosmetic sheet is stuck to the skin, the interface between the skin patch layer and the skin The polyoxyethylene sorbitan fatty acid ester showing lipophilicity is stored. Therefore, the skin surface exhibiting oiliness can be wetted in a short time, and as a result, the removal performance of the square plug can be improved. Moreover, since the inorganic filler is contained, the cosmetic sheet excellent also in mechanical strength is realizable.

The cosmetic sheet of the present invention is useful for a square plug removal sheet such as a peel-off type pack, an acne sheet, and the like, and can particularly be applied to a complexly curved skin such as a nose. It can be effectively used as a corner plug removal sheet.

  The present invention will be described more specifically with reference to the following examples. However, the present invention is not limited to these examples, and various applications are possible without departing from the technical idea of the present invention.

Example 1
58% by weight of polyvinylpyrrolidone having a weight average molecular weight of 1,200,000 as a water-soluble polymer, 6% by weight of sorbitan oleic acid monoester (ethylene oxide 20 mol adduct, HLB 15.0) as polyoxyethylene sorbitan fatty acid ester, anhydrous Using 34% by weight of silicic acid and 2% by weight of titanium oxide, these were stirred and mixed with an appropriate amount of purified water to prepare a coating solution. This coating solution is applied to one side of a polyethylene film (thickness 50 μm) that has not been subjected to a release treatment so that the coating amount is 110 g / m ² and a uniform thickness is formed to form a skin adhesive layer. A spunlace nonwoven fabric (basis weight: 40 g / m ² ) made of polyester fiber was layered on the layer and dried at 100 ° C. for 1.5 minutes to prepare a three-layer cosmetic sheet. The moisture content of the obtained cosmetic sheet was 15 to 20% by weight. However, the water content was calculated from the change in weight after storage for about 24 hours at room temperature. In addition, the obtained cosmetic sheet was hermetically stored in a storage bag in which aluminum and a polyester film were laminated in order to prevent evaporation of moisture in the sheet.

(Comparative Example 1)
In Example 1, a coating solution was prepared in the same manner as in Example 1 except that polyoxyethylene sorbitan fatty acid ester was not used and 6% by weight of glycerin was used instead. A cosmetic sheet was prepared in the same manner as in Example 1 except that this coating solution was applied to the silicone-treated surface of a polyethylene film (thickness 50 μm) having a silicone treatment on one side. However, the water content was 15 to 20% by weight. The obtained cosmetic sheet was stored in the same manner as in Example 1.

As a reference example, a commercially available cosmetic sheet was used, and for the cosmetic sheets prepared in Example 1 and Comparative Example 1, the square plug removal ratio was determined as shown below.
That is, the cosmetic sheets of Example 1, Comparative Example 1, and Reference Example were cut into appropriate sizes (2.5 cm × 3.0 cm). An appropriate amount of water was applied to one of the nose parts of 60 healthy adult volunteers, and then this cosmetic sheet test piece was attached. It left for about 10 minutes in the state stuck in this way, and peeled, after the cosmetic sheet dried. The number of square plugs adhering to the skin patch layer of the cosmetic sheet peeled for each volunteer was counted.
Next, assuming that the number of square plugs removed using the cosmetic sheet of the reference example was 1, the square plug removal ratio of Example 1 or Comparative Example 1 was determined. That is, based on the following formula, the number of square plugs removed using the cosmetic sheet of Example 1 or Comparative Example 1 is divided by the number of square plugs removed using the cosmetic sheet of Reference Example. The horn plug removal rate was determined. However, the horn plug removal ratio of Example 1 and Comparative Example 1 is shown as an average value of the obtained values.

Square plug removal ratio = number of square plugs removed in Example 1 or Comparative Example 1 / number of square plugs removed in Reference Example

In the test, 60 volunteers were divided into three groups, and in the first group, the cosmetic sheet of the example was applied to one half of the nose and the cosmetic sheet of the reference example was applied to the other half. In the second group, the cosmetic sheet of the comparative example is applied to one half of the nose, and the cosmetic sheet of the example is applied to the other half. In the third group, the reference example is applied to one half of the nose. The test was conducted with the cosmetic sheet of the comparative example attached to the other half of the decorative sheet.

  As a result of the evaluation, the result of the square plug removal ratio of Example 1 was 1.3, and the result of the square plug removal ratio of Comparative Example 1 was 0.95. That is, Example 1 which is a cosmetic sheet of the present invention shows a corner plug removal rate 1.3 times that of the reference example, while Comparative Example 1 has a corner plug removal rate of 0. It was 95, and it showed only a corner plug removal property substantially equivalent to the reference example.

(Comparative Example 2)
A coating solution was prepared in the same manner as in Example 1. Example except that this coating solution was applied to one surface of a polyethylene film (thickness 50 μm) subjected to silicone treatment so that the coating amount was 110 g / m ² and a uniform thickness to form a skin adhesive layer. A cosmetic sheet was produced in the same manner as in Example 1. The moisture content of the cosmetic sheet was 15 to 20%. The obtained cosmetic sheet was stored in the same manner as in Example 1.

  For the cosmetic sheets obtained in Example 1, Comparative Example 1 and Comparative Example 2, the separator peeling force was measured by the method described below. The result is shown in the graph of FIG.

[Measurement method of peel strength of separator]
As test samples, three test pieces having a width of 20 mm and a length of 10 mm were cut out from the cosmetic sheet. The back side of the test piece on the separator side was pressure-bonded with a roller to the double-sided tape part of the phenolic resin laminate on which the double-sided tape was attached (pressure 2 kg). Next, using a tensile tester, the end of the test piece was pulled under the conditions of a tensile angle of 90 ° and a tensile speed of 300 mm / min, and the peel force of the test piece was measured. In addition, the peeling force took the average value regarding the three test pieces.

  As is clear from FIG. 1, the peel force of Example 1 was 438 mN / 20 mm, and the peel force of Comparative Example 2 was 181 mN / 20 mm. That is, the cosmetic sheet of Example 1 was found to have a separator peel strength 2.4 times that of Comparative Example 2. Moreover, since the layer of polyoxyethylene sorbitan fatty acid ester was not formed in the surface of the skin sticking layer in the cosmetic sheet of the comparative example 1, the peeling force of the separator was 356 mN / 20mm. It was found that the cosmetic sheet of Example 1 of the present invention had a separator peeling force substantially equal to that of Comparative Example 1 or slightly larger than that and did not cause light peeling.

  That is, according to the present invention, a polyoxyethylene sorbitan fatty acid ester is present on the surface of the skin patch layer and is a cosmetic sheet capable of improving the removability of horn plugs, and light peeling occurs during production. A cosmetic sheet that can be cut into an arbitrary shape without being lightly peeled during storage and can protect the skin adhesive layer in terms of hygiene and adhesive strength until use is obtained. be able to. Further, since the skin patch layer contains polyoxyethylene sorbitan fatty acid ester which is a nonionic surfactant, it can relieve pain when peeling from the skin.

  The cosmetic sheet of the present invention is useful as a horn plug removal sheet, an acne sheet, and the like, and can be effectively used as a horn plug removal sheet such as a nose.

FIG. 1 is a graph showing the measurement results of the separator peeling force of the decorative sheets of Example 1, Comparative Example 1, and Comparative Example 2.
