When the processing amount is larger than 1 × 10 ^-2 equivalent / cm ² , the non-adhesive treatment of the non-adhesive surface is sufficiently performed,
It does not work any more. Here, the cross-linking equivalent of the cross-linking factor refers to the amount of the cross-linking points of the cross-linking factor expressed in moles.

When a non-adhesive treating agent is applied to one surface of the synthetic polymer gel body for producing the pore tightening pack material, the surface may be treated with a uniform treatment amount on one surface. However, the processing amount may be partially non-uniform. Therefore, the surface may be non-uniformly treated within the above-mentioned preferable treatment amount.

Regarding the thickness of the sheet used in the present invention,
It may be set appropriately according to the use situation, evenly over the whole, may be partially different in thickness, but considering the discomfort and strength when affixed to the skin, 0.1
It is preferably in the range of 〜3 mm. If the thickness of the entire sheet is less than 0.1 mm, the strength of the pore-tightening pack material may be reduced. On the other hand, if it exceeds 3 mm, the self-weight of the sheet becomes too large, and there is a possibility that an uncomfortable feeling may be caused when the sheet is attached to the skin.

The pore-tightening pack material of the present invention has an opening inside the gel body for the purpose of improving the tear strength and handleability of the pore-tightening pack material without impairing the transparency of the pore-tightening pack material. A woven or non-woven fabric having a sufficiently large ratio can be included in the thickness direction.

The above-mentioned woven or nonwoven fabric having a large aperture ratio has a large aperture ratio (maintains transparency) so that a 10-point type can be read through the woven or nonwoven fabric.

[0056] In addition to the above-mentioned various components, various additives other than the above-mentioned various components can be appropriately blended with the pore-tightening pack material of the present invention within a range that does not cause opacity. For example, in addition to medicinal ingredients for the treatment of beauty, beauty and skin, etc., humectants, thickeners, fragrances, coloring agents, stabilizers, antioxidants, ultraviolet absorbers, tackifiers, pH adjusters, chelates And additives such as surfactants, surfactants, preservatives, and antibacterial agents.

Examples of humectants include ethylene glycol, propylene glycol, butylene glycol, diethylene glycol, dipropylene glycol, glycerin, diglycerin, sorbitol, malbitol, trehalose, raffinose, xylitol, mannitol, hyaluronic acid and salts thereof, polyethylene glycol, Glycols such as polyglycerin, polyhydric alcohols, polysaccharides and the like can be mentioned. These are preferably used alone or as a mixture of two or more.

Hereinafter, an example of a method for producing a pore tightening pack material using a synthetic polymer having a network structure will be described. The pore-tightening pack material is a synthetic polymer having a network structure constituting the gel body, and (g) a copolymer of one or more polymerizable unsaturated monomers and a crosslinkable unsaturated monomer. Or (h) a carboxyl group, a sulfonic acid group, a hydroxyl group,
A hydrophilic synthetic polymer obtained by polymerizing one or more polymerizable unsaturated monomers having at least one functional group selected from the group consisting of an amide group and an amino group, and a polyvalent metal It is preferably a crosslinked structure obtained by reacting with at least one type of crosslinking factor selected from the group consisting of ionic compounds, polycarboxylic acids, polyhydric alcohols, polyfunctional epoxides and dialdehydes.

When the copolymer of the polymerizable unsaturated monomer and the crosslinkable unsaturated monomer (g) is used as a synthetic polymer having a network structure, a method for producing a gel is as follows. For example, a method in which a polymerizable unsaturated monomer, a crosslinkable unsaturated monomer, and a polymerization initiator are added to a solvent constituting a gel to carry out polymerization. For the polymerization, a system in which the polymerization is started by heating or light irradiation or by adding a polymerization initiator may be selected.

On the other hand, when the crosslinked structure obtained by reacting the hydrophilic synthetic polymer of (h) with a crosslinkable factor is used as a synthetic polymer having a network structure, a method for producing a gel body includes the following: For example, there is a method in which a hydrophilic synthetic polymer polymerized in advance in the same manner as described above is dissolved, and a crosslinking reaction is performed by adding a crosslinking factor to the solution. The cross-linking reaction may be started by heating or may be started by adding a reaction initiator. Alternatively, a system in which a crosslinking reaction starts immediately upon addition of a crosslinking factor may be selected.

In the case where a gel is obtained by polymerizing the unsaturated monomer of the above (g), when thermal polymerization is carried out using a solution in which the above-mentioned monomer and solvent are mixed, azobiscyanovaleric acid or Azo-based polymerization initiators such as azobisaminopropane dihydrochloride, or reducing agents such as ferrous sulfate, dithionite, pyrosulfite and hydrogen peroxide, t-butyl hydroperoxide, peroxodisulfate The polymerization can be carried out by adding a redox polymerization initiator comprising a peroxide such as These azo-based polymerization initiators and redox-based polymerization initiators may be used alone or in combination as needed. In the case where a redox polymerization initiator is used, a system in which polymerization is initiated only by adding it without heating may be used. In the case of photopolymerization, photoradical polymerization initiators such as acetophenone, benzoin ether, phosphorus, benzophenone, thioxanthone, and azo, and cationic photopolymerization such as diazonium salts, diallyliodonium salts, and triarylsulfonium salts. Polymerization can be carried out by adding an initiator or the like.

The thickness of the pore-tightening pack material is adjusted by, for example, using an extruder or a doctor blade or the like to spread the gel-forming composition before the curing of the gel body, or by adjusting the thickness to a predetermined thickness. This is performed by filling a container having the composition, for example, a blister container.

In the latter method of filling a container having a predetermined thickness, if the shape of the container is formed in accordance with the shape of the pore-tightening packing material at the time of use, the in-line manufacturing process is facilitated, and the manufacturing process is facilitated. It becomes more preferable. Furthermore, compared with the method of forming a long belt-like gel body and punching it into the intended shape at the time of use, the amount of gel to be discarded is reduced, and since there is no contact between the gel body and the punching blade, sanitary It is also preferable from the viewpoint of being appropriate.

The method for treating one surface of the pore-tightening pack material with the above-mentioned non-adhesive treating agent is as follows: (i) After the curing of the gel body is completed, the surface is treated with the non-adhesive treating agent. Before the curing of the gel body (j), the surface thereof may be treated with a non-adhesive treating agent. In addition, "the completion of the curing of the gel body" in the present invention means that the compound before gelation has undergone a gelling reaction and is in a state having shape retention.

The production method in the case of the above (i) is as follows. One surface of the cured gel body is coated with, for example, a coater,
A method of applying a non-adhesive treatment agent by a method such as coating using a printing machine, brush or the like, or spraying using a spray or the like is preferable.

In the case of the above (j), the production method may be such that, for example, a coater, a printing machine,
A method of applying a non-adhesive treatment agent by a method such as coating using a brush or spraying using a spray or the like is preferable.

However, as the manufacturing conditions in the case of the above (j), the gel-forming composition when one of the surfaces of the gel-forming composition before curing is treated with a non-adhesive treating agent is not less than a certain amount. It is desirable to have a viscosity. The viscosity is preferably 1,000 centipoise or more. That is, when the viscosity of the gel-forming composition when treated with the non-adhesive treating agent is smaller than 1,000 centipoise, the gel-forming composition and the non-adhesive treating agent are mixed,
The effect of the non-adhesive treating agent acts on the other surface that has not been treated, and as a result, there is a possibility that there is no difference in the degree of adhesion between both surfaces of the produced pore tightening pack material.

In the production method in the case of the above (j), when the thickness of the gel-forming composition before the completion of curing is adjusted, a non-adhesive treating agent is applied to the gel-forming composition. It is also possible to cause a difference in the degree of adhesion between both surfaces of the pore-tightening pack material. That is,
When adjusting the thickness of the gel-forming compound before the end of curing,
A sheet that can have a non-adhesive treatment agent
Intervening sheet), a non-adhesive treating agent is interposed on one side, the interposed sheet is placed on the gel-forming composition before the completion of curing, and the gel before curing is completed using a doctor blade or a squeegee. Adjust the thickness of the forming composition. As a result, the non-adhesive treating agent held by the interposed sheet can be transferred to the gel-forming composition, and this is allowed to stand until the completion of the curing of the gel body, whereby the desired adhesion of both surfaces is achieved. Pore tightening packs of different degrees can be obtained.

In the case of such a production method, the viscosity of the gel-forming composition immediately before the thickness adjustment is performed is 10,000 to 2.0.
Preferably, it is 0.000 centipoise. That is, if it is smaller than 10,000 centipoise, the gel-forming composition and the non-adhesive treating agent mix, and the effect of the non-adhesive treating agent acts on the other untreated surface. There is a possibility that no difference occurs in the degree of adhesion between the two surfaces of the pack material.
Also, if it is larger than 2,000,000 centipoise,
It becomes difficult to adjust the thickness of the gel-forming composition itself.

The intermediate sheet may be any sheet as long as the non-adhesive treating agent can be interposed on one side, and examples thereof include a plastic sheet, a sponge sheet, paper, woven cloth, and nonwoven cloth. The intervening sheet is
A plastic sheet or the like that is easy to peel off is preferable because it is peeled off from the pore-tightening pack material before use.

In order to make the non-adhesive treating agent easily intervene in the interposed sheet, a thickener can be added to the non-adhesive treating agent.

Until the pore-tightening pack material is used, a plastic film of polyethylene, polypropylene, polyethylene terephthalate or the like is left as it is on at least the adhesive surface side, or a release of silicone resin or the like is performed on the surface of the plastic film. It is necessary to paste it as release paper with the agent applied or baked
Sanitary preferred. In addition, it is preferable to apply the release paper to the non-adhesive surface side in order to prevent drying of the pore-tightening pack material and from the viewpoint of hygiene.

Since the release paper that has been pasted is not flexible enough to follow the movement of the skin surface, it must be peeled off at the time of use. If the release paper is used with the release paper adhered to the non-adhesive surface, the release paper will peel off from the pore-tightening pack material during use, making it difficult to handle. The release paper may be used as an underlay or a surface material during the gel production process of the pore-tightening pack material, or may be attached after the production of the pore-tightening pack material is completed.

The shape of the pore-tightening pack material of the present invention is not particularly limited as long as it is a shape suitable for application to the face centering on the nose. For example, the shape of the nose shown in FIG.
It is preferably cut or molded into a shape that fits the nose, such as a triangle or a trapezoid. In addition, to apply to cheeks, foreheads, chins, etc., further squares, rectangles, ellipses, circles,
A heart shape, a semicircle, a semiellipse, or a combination thereof can be used. It is also preferable to provide a mark on the center line with an uneven portion, printing, slit, notch, etc. to facilitate positioning, and to prevent the sheet from floating in the shape of a nose, It is also possible to provide a slit at the center, and to form a projection at the center of the lower end so as to cover the head of the nose.

Also, the pore packing material of the present invention is
It can be used daily when pores are felt open, but it is preferable to use it after using a plug material (sheet or peel-off type) of a keratotic plug removal type. At this time, it is preferable to wash off the pack material of the horn plug removal type remaining on the skin once before use.

The components other than the crosslinking factor (synthetic aluminum silicate) among the gel-forming compounds shown in Table 2 were mixed,
After kneading at 50 ° C. for about 30 minutes to make it uniform, the above-mentioned crosslinking factor was added and kneading was further made at 60 ° C. for about 10 minutes to make it uniform. The gel-forming composition thus obtained was applied to a thickness of 1
On a polypropylene sheet of 00 μm, spread evenly to a thickness of 0.8 mm using a doctor blade, and use a roller from above to mix a 15-denier nylon tulle woven fabric that satisfies the above conditions with a roller. It was immersed in an object. This was allowed to stand at room temperature for about 2 hours to complete the curing of the gel, thereby forming a transparent synthetic polymer gel.

A non-adhesive treating agent obtained by dissolving a cross-linking factor (potassium alum decahydrate) shown in Table 2 in a solvent (purified water) was uniformly coated on the above synthetic polymer gel using a brush.
It was painted and treated at 3 mg / cm ² (ie, 4 × 10 ⁻⁸ equivalent / cm ^{2 in} crosslinking equivalent). Further, a polypropylene sheet having a thickness of 50 μm is placed on the surface of the transparent gel body treated with the non-adhesive treating agent, and a nose-shaped and two linear center slits (1) shown in FIG.

The evaluation results of the examples and the comparative examples are shown below. For each evaluation, before going to bed (after bathing), use a commercially available plug material for removing plugs, remove the plugs, visually check the state in which the pores are widened, and then use the following standard for the test sample. We asked them to use it in time and asked the results to be answered in a questionnaire. The test site was performed by nose.
As for the time for sticking, etc., Example 1 was 20 minutes, Comparative Example 1

From the results shown in Table 4, it was found that the examples of the present invention were superior to the comparative examples in all of the evaluation results. Comparative Example 1 was a sheet-shaped impregnation type product, but could not sufficiently close pores. Comparative Example 2 was a product in which a tightening component was added to a serum-type product, but the effect was low. In the first embodiment, in the latter half of the application time,
It was found that as a result of the sheet shrinking as the sheet dries, the pores are more effectively closed. On the other hand, the effect of the impregnated type was not recognized because the sheet did not shrink. Further, those of Examples of the present invention were transparent in appearance, and were very popular including ease of use.
