Description

  The present invention relates to a sheet for body patching that allows carbon dioxide to act on the skin and obtains a preventive and therapeutic effect for skin diseases and a cosmetic effect due to its blood circulation promoting effect.

  Conventionally, as cosmetics using the blood circulation promoting action of carbon dioxide, cosmetics that promote blood flow containing carbon dioxide in a pressure-resistant container (Patent Document 1), so as to promote carbon dioxide penetration into the skin. Known are carbon dioxide-containing cosmetics containing 10 to 99.9% polyhydric alcohol (Patent Document 2), and cosmetics with high viscosity (Patent Document 3) to suppress volatilization of carbon dioxide after jetting. It has been. However, these forms use a high-pressure gas container (aerosol can), or put a liquid (including high-viscosity gel) in a sealed container and squirt on the skin for use. The action time of carbon dioxide sprayed on the skin is extremely short, and there is a problem that a satisfactory blood circulation promoting effect cannot be obtained. In order to extend the action time of carbon dioxide, it was necessary to keep spray gel or the like thickly applied on the skin, and it was necessary to wipe off or wash away after use.

On the other hand, as a method of supplying carbon dioxide to the body without using a high-pressure vessel, etc., there is a technique of generating carbon dioxide gas by reacting carbonate and acid, but when using it for the body, it reacts Moisture and the like are necessary for this, and a complicated mechanism (Patent Document 4) is required as a place of use (tub) or form of use. On the other hand, there is a method (Patent Document 5) in which a cloth wetted with water is used repeatedly when used as a shipping agent, but the skin is inflamed due to the high concentration of salt solution adhering to the skin. There's a problem. Further, Patent Document 6 is known as a method for supplying carbon dioxide transcutaneously for the purpose of promoting wound healing of the skin, etc., and this also provides dry ice, carbonate and acid as a carbon dioxide supply source. In addition, it is complicated in terms of equipment such as supply from a cylinder, and the moisture permeation amount of the gas permeable material is very small, and it is impossible to actually supply the moisture amount necessary for promoting blood circulation in the skin. Further, a carbon dioxide percutaneous absorption composition (Patent Document 7), which is a water-soluble polymer composition containing a high concentration of free carbonic acid and comprising a sol-gel transition composition, is known. It is described that this composition can suppress the volatilization of carbon dioxide gas by gelling, and it is shown that a sol in which a high concentration of carbon dioxide is dissolved is gelled after being applied to a sheet material. . However, there is no specific means to prevent the volatilization of carbon dioxide when it is applied to the sheet and when it is cooled and solidified, and it is difficult to actually supply carbon dioxide to the skin sufficiently. It is done. In addition, when processed on a sheet, there is a problem that the action is delayed (reddening for 5 minutes or more is delayed).

  An object of the present invention is to provide a means for supplying carbon dioxide to the skin which is not irritating to the skin, can be continuously supplied to the skin, can be easily manufactured, and has good usability.

  Then, this inventor devised producing the nonwoven fabric containing the liquid or gel containing a carbon dioxide, and setting it as the form for body sticking. However, in this form, even if it is a gel-like sheet, carbon dioxide will be volatilized, but if this non-woven fabric is laminated with a carbon dioxide poorly permeable film, it has been found that volatilization of carbon dioxide after sticking can be prevented. . In addition, carbon dioxide has a sufficient blood circulation promoting effect if it is filled in a certain amount after sealing a laminated sheet of a nonwoven fabric holding a liquid or gel and a carbon dioxide impermeable film in a carbon dioxide impermeable container. It has been found that carbon dioxide can be dissolved in a liquid or gel. Furthermore, if it is a means to partially join as a means for laminating the nonwoven fabric and the film, the fit to the skin is improved, and even if it is applied to an uneven part such as the entire face, volatilization of carbon dioxide is prevented. The present inventors have found that carbon dioxide can be connected to the skin in a connected manner and the feeling of use is improved.

  That is, the present invention is a body sticking sheet in which a sheet obtained by laminating a carbon dioxide impermeable film and a nonwoven fabric is enclosed in a carbon dioxide impermeable container, and the laminating means is a carbon dioxide impermeable film and A non-woven fabric is partially joined, and a liquid or gel containing carbon dioxide and moisture is held in at least a part of the non-woven fabric. The present invention provides a body sticking sheet characterized by being filled up to 5 times.

  According to the present invention, carbon dioxide can be supplied quickly and continuously over a wide range such as an uneven face with a simple operation without skin irritation. An effect is obtained. Therefore, the body patch sheet of the present invention can be used for cosmetics that can be expected to be effective in improving blood flow in the skin, prevention and treatment of pressure ulcers, prevention and treatment of swelling and edema, anti-inflammatory analgesia for stiffness and pain, etc. It can also be applied to.

  As shown in FIG. 1, for example, the sheet for body sticking of the present invention is a sheet in which (A) a carbon dioxide-impermeable film and (B) a non-woven fabric are laminated, and (C) a carbon dioxide-impermeable container is enclosed. A body sticking sheet, wherein a liquid or gel containing carbon dioxide and moisture is held on at least a part of the nonwoven fabric.

(B) By laminating the non-permeable carbon dioxide film on the nonwoven fabric, the carbon dioxide volatilization from the non-sticking surface can be suppressed when the nonwoven fabric side is affixed. Can supply. In addition, in the present invention in which carbon dioxide is filled in a nonwoven fabric liquid or gel by filling the laminated sheet in a container and then filled with carbon dioxide, this hardly permeable film requires a certain degree of carbon dioxide permeability. Therefore, carbon dioxide permeability is 100,000cc / m ² · day · atm (25 ° C) or less (ASTM D-1434) or less, especially 10,000 cc / m ² · day · atm (25 ° C) or less. Those having the following are preferred. Such a film having carbon dioxide permeability of 100,000 cc / m ² · day · atm or less is preferably on the side opposite to the surface of the laminated sheet that adheres to the skin. In addition, here, the film which has such a carbon dioxide permeability should just have the property itself, and may have a hole. Further, where the carbon dioxide permeability ^{100,000cc / m 2 · day · atm} (25 ℃) corresponds to ^{10,130mL / m 2 · (24hr)} · MPa.

As this film (A), for example, a film of polyethylene, polypropylene, soft vinyl chloride, polyester, nylon, polyurethane, ethylene / vinyl acetate copolymer or the like can be used. Moreover, the film which vapor-deposited aluminum on these, the film which vapor-deposited glass, and the film which laminated these further can also be used. About the thickness of a film, about 1-100 micrometers in the case of a normal film, Preferably it is about 20-40 micrometers, and the thing of 0.3-1 mm can be used in the case of a foam film. In the case of a film having a lower carbon dioxide permeability of 7,000 cc / m ² · day · atm (25 ° C.) or less (for example, vinyl chloride, polyethylene terephthalate, various deposited films, multilayer films, etc.) The use of a film of about ˜20 μm is preferred.
In addition, in order to suppress the carbon dioxide permeability in an environment where a large amount of moisture exists, or to obtain heat resistance when bonded to a nonwoven fabric by heat sealing, polyethylene and nylon, or polyethylene and ethylene / vinyl acetate copolymer It is also preferable to use a multilayer film such as

Examples of the nonwoven fabric (B) include synthetic fibers such as nylon, polypropylene, polyester, polyethylene, polystyrene, polyurethane, and polyolefin, and natural fibers made of pulp, silk, cotton, hemp, rayon, collagen, and the like. A mixture of the above may also be used. The basis weight of these is about ²⁰ to 100 g / m ² , more preferably about ²⁰ to 70 g / m ² , and the heat of hot melt mixed with heat-fusible fibers for bonding with the film (A). An adhesive may be attached.

The lamination means of the non-woven fabric (B) and the film (A) is partially joined, such as fit to the skin (particularly fit when applied to uneven parts such as the face), texture, etc. This is preferable. When there are few joint points in the partial joining, the degree of freedom of the nonwoven fabric is maintained, the fitting property is good, and the liquid permeability is also good. On the other hand, when there are too few joint points, there is a difficulty in use such as peeling off the film and the nonwoven fabric when opening the sheet at the time of use, and difficulty in opening only with the film. Therefore, as a partial joining method, the shortest distance between the joining points is preferably 3 to 30 mm, more preferably 3 to 20 mm, and particularly preferably 5 to 15 mm.
In addition, when using dot bonding (heat sealing) or an adhesive, the portion with the shortest distance of 3 mm or less is required for manufacturing to obtain hardness for a part of the sheet or to suppress peeling between the film and the nonwoven fabric. May be part of it.

  One junction point is preferably small. The shape of the joint is not particularly specified as linear, circular, or quadrangular, but its short width (linear line width, circular diameter / elliptical minor axis, rectangular short side) is 0. 1-5 mm, preferably 0.3-5 mm, more preferably 1.0-2.0 mm. In addition, the area ratio of the joint points in a certain area is 0.1 to 50%, further 1 to 20%, because it increases the degree of freedom and prevents the possibility of adhesion and peeling during use. The range of 2 to 10% is particularly preferable. It is preferable to disperse the junction points in the form of dots, but various shapes such as letters and heart shapes can be used in terms of design and the like. A combination of several shapes may be used. A dotted line shape can also be used. In addition to thermal fusion and ultrasonic fusion, in the case of bonding using an adhesive, in addition to the dot-like method described above, the adhesive is sprayed into a yarn and is irregularly shaped into a line or spider web The partial joining method can also be used from the texture and fit. Further, as a bonding method, polyethylene or the like can be laminated between the film and the nonwoven fabric and bonded at multiple points.

The container (C) for enclosing the laminated sheet is carbon dioxide impermeable. Here, the non-permeability means that the carbon dioxide permeability is 50 cc / m ² · day · atm (ASTM D-1434) or less. Preferable materials are those having heat-sealing properties, specifically, a laminate film laminated with an aluminum foil, a laminate film having an aluminum deposited layer, a polyvinylidene chloride film, a laminate film containing a polyvinylidene chloride layer, and the like. It is done. The form of the container (C) is preferably a flat bag or a gusset.

  A liquid or gel containing carbon dioxide and moisture is held in at least a part of the nonwoven fabric of the laminated sheet. Here, the dissolved carbon dioxide concentration in the liquid or gel is 100 to 3,000 ppm (at 25 ° C.), more preferably 100 to 2,000 ppm, more preferably 500 to 2,000 ppm, particularly 800 to 1,800 ppm in terms of blood circulation promoting effect. Is preferred.

  As a form of the nonwoven fabric which retains the liquid or gel which dissolves carbon dioxide, a nonwoven fabric impregnated with a carbon dioxide-dissolved liquid, a nonwoven fabric coated with a carbon dioxide-dissolved gel, and the like can be given.

In the present invention, from the viewpoint of obtaining a blood circulation promoting effect when applied to the skin, (A) carbon dioxide (CO ₂ ) needs to be dissolved in the liquid or gel of the nonwoven fabric. Since carbon dioxide becomes carbonate (CO ₃ ²⁻ ) under alkaline conditions, the pH of the liquid or gel of (A) non-woven fabric is 3.5 to 6.5, preferably 5. 0 to 6.5. The water content of the liquid or gel is preferably 2% by mass or more. A more preferable water content is 2 to 99.5% by mass, a still more preferable water content is 10 to 99.5% by mass, and a particularly preferable water content is 60 to 99.5% by mass.
Further, the amount of the liquid or gel retained in the nonwoven fabric of the present invention is preferable because the amount of carbon dioxide retained increases as the amount per unit area increases. 0.0 g / cm ² , more preferably 0.05 to 0.5 g / cm ² is preferable.

  In the present invention, the carbon dioxide is introduced into the container after a sheet laminated with a nonwoven fabric and a film impregnated or coated with a liquid or gel containing moisture is put into the container, or a sheet laminated with a nonwoven fabric and a film is placed in the container. After being charged and subsequently filled with a liquid containing moisture, it is filled in an amount of 0.5 to 5 times, preferably 1.0 to 3.0 times the volume of the liquid or gel containing water in the sheet. To dissolve in the liquid or gel. Here, if the carbon dioxide filling amount is less than 0.5 times the amount of the liquid or gel, the dissolved carbon dioxide concentration in the liquid or gel does not become a concentration that provides a sufficient blood circulation promoting effect. Moreover, when the carbon dioxide filling amount exceeds 5 times the amount of the liquid or gel, the container for the contents (sheets) becomes too large, causing problems in terms of handling, transportation, packaging costs, and the like.

  By adopting a means for filling carbon dioxide after previously putting the laminated sheet into the container in this way, the filled carbon dioxide is a sufficient amount to exert the blood circulation promoting effect in the liquid or gel of the nonwoven fabric. Dissolve. Therefore, the manufacturing process of the sheet for body sticking of the present invention is simple.

  The liquid or gel of the nonwoven fabric preferably contains an oil that is liquid at 25 ° C. from the viewpoint of dissolving carbon dioxide at a high concentration. This is preferable because a liquid hydrophobic substance dissolves about 3 to 6 times as much carbon dioxide as water, and a liquid oil that is incompatible with water is dispersed in water as an emulsion to maintain this solubility characteristic. And dispersed in the liquid or gel. Examples of the oil include long chain hydrocarbons, higher fatty acids, higher fatty acid esters, higher alcohols, silicones, and fluorocarbons. As long-chain hydrocarbons, liquid paraffin is preferred, and higher fatty acids, higher fatty acid esters, and higher alcohols include branched fatty acids, unsaturated fatty acids, branched fatty acid esters, unsaturated fatty acid esters, branched fatty alcohols, and unsaturated fatty alcohols. It is preferable because it exhibits a liquid state.

As silicones, alkyl-modified silicone such as dimethylstearyl polysiloxane, highly polymerized methyl polysiloxane, cross-linked methyl polysiloxane, fluorinated fluorosilicone, and the like are preferable. Furthermore, as fluorocarbons, perfluoropolyethers such as 2- (perfluorohexyl) ethyl 1,3-dimethylbutyl ether, hydrofluoroethers, and the like can be used. These oils are preferably contained in the liquid or gel of the nonwoven fabric in an amount of 1 to 35% by mass, further 1 to 20% by mass, and particularly 1 to 15% by mass.

  Various emulsifiers can be added to the liquid or gel of the nonwoven fabric in order to improve the dispersion of various oils and plant extracts and the adhesion to the skin. For example, nonionic surfactants such as glycerin monofatty acid ester, polyglycerin monofatty acid ester, sorbitan monofatty acid ester, polyethylene glycol monofatty acid ester, polyoxyethylene sorbitan monofatty acid ester, polyoxyethylene hydrogenated castor oil; Anionic surfactants such as -18 linear or branched fatty acid salts, alkyl phosphate salts having 12 to 18 carbon atoms, N-acyl amino acid salts; cationic interfaces such as stearyltrimethylammonium chloride and distearyldimethylammonium chloride Mention may be made of activators.

Antibiotics other than plant extracts, antifungal agents, anti-inflammatory agents, blood circulation promoters, vitamins (water-soluble vitamin C, fat-soluble vitamin A, vitamin E, tocopherol derivatives, vitamin C derivatives, etc.), moisturizers Etc. can also be blended. Furthermore, mineral powders such as kaolin, sukumite, zinc oxide, titanium oxide and the like can be blended.

  In forming the gel, a water-soluble polymer, a polyhydric alcohol, or the like can be used. Here, as the water-soluble polymer, for example, a crosslinked hydrous gel comprising polyacrylic acid and a crosslinking agent; polymethacrylic acid, polyacrylamide, polyvinyl alcohol, polyvinylpyrrolidone, carboxymethylcellulose and its salts, alginate, pectin and many others. Examples include gels composed of valent cations; water-containing gels using water-soluble polymers such as carrageenan, xanthan gum, gelatin, gellan gum, pullulan, agar, gum arabic, chitosan and derivatives thereof, and water.

  More preferable carbon dioxide filling means in the present invention is a means for putting a laminated sheet into a container, then putting a liquid containing moisture, and then filling carbon dioxide; or laminating a film after forming a gel on one side of a nonwoven fabric. This is a means for producing a prepared sheet, putting it into a container, and then filling it with carbon dioxide. At this time, the laminated sheet is preferably put into the container as two-fold, four-fold or the like. Usually, the sheet is folded in such a state that the surfaces of the liquid or gel come into contact with each other. However, the sheet may be folded with the non-woven fabric surface outside in order to accelerate the immersion of the internal solution.

  In the laminated sheet used in the present invention, among the laminated nonwoven fabric and film, it is easy to fold that only the film is provided with holes and / or slits, promote penetration of the impregnating solution, and fit when applied to the body. It is preferable from the viewpoint of improving the property and preventing volatilization of dissolved carbon dioxide. Such a form in which a slit is provided only in a film is shown in FIGS. In addition, a notch means here the cutting part which followed the circumference | surroundings, and a slit means the cutting part independent of the circumference | surroundings.

  Further, for example, as shown in FIGS. 5 to 7, it is assumed that slits are provided in both the nonwoven fabric and the film of the laminated sheet in addition to the slits from the surroundings. This is preferable in terms of improving fit, preventing volatilization of carbon dioxide, and ease of folding.

  Moreover, as a shape of the sheet | seat for body sticking of this invention, it can also be set as the shape of a face mask other than the shape of normal skin patches, such as a square and a rectangle.
