It is possible to form a sheet-like hydrogel with reduced remaining problems. Also disclosed is a poultice having a sheet-like hydrous plaster formed from a plaster base obtained by further mixing agar with a gelatin-based base with the intention of further improving the water content and shape retention. (See Patent Document 1).
- Patent Document 1 JP-A-57-42617
- gelatin may not be blended so that the components that can be added are not limited by the pH of the plaster base.
- the plaster In a conventional plaster base not containing gelatin, the plaster has a sufficient water content. It cannot be used, and the feeling of use such as a feeling of moisture is reduced.
- the water content of a conventional paste base containing no gelatin is increased, there is a problem in that the formed paste strength is oozing out of water and the stickiness of the paste is insufficient. On the other hand, if it is attempted to suppress the exudation of water, the plaster becomes too sticky or sticky.
- the present invention has been made in view of the above-mentioned problems of the related art, and it has been found that even a composition containing a desired component and having a desired pH can sufficiently provide a feeling of use such as a moist feeling.
- Another object of the present invention is to provide a patch in which oozing of water from the plaster is sufficiently reduced and which has a sufficient adhesive strength.
- a sheet-like plaster formed from a plaster base containing 70% by mass or more of moisture has a sufficiently excellent moist feeling.
- a plaster having a sufficient water content can be formed into a sheet without containing gelatin, and
- the present inventors have found that the sheet-like plaster has excellent shape-retaining properties and adhesive strength, and has sufficiently reduced the bleeding of water, thereby completing the present invention.

- (a) contains substantially no gelatin
- (b) contains 70% by mass or more of water
- (c) contains 3.0% to 10% by mass of a water-soluble polymer
- (d) ) Xanthan gum and / or polyvinylpyrrolidone are contained in a total amount of 0.01% by mass to 1.4% by mass.
- the patch of the present invention includes a water-containing plaster formed by forming a plaster base having the above characteristics in a sheet shape.
- substantially free of gelatin means that no gelatin is contained, It means that the amount thereof does not affect the jelly strength of the pressure-sensitive adhesive layer formed from the pressure-sensitive adhesive base.
- a force affecting the jelly strength of the pressure-sensitive adhesive layer can be determined by the following method. That is, the jelly strength of the pressure-sensitive adhesive layer formed from a certain amount of gelatin contained in the pressure-sensitive adhesive base is larger or changed with respect to the jelly strength of the pressure-sensitive adhesive layer formed from the certain pressure-sensitive adhesive base. In that case, it is determined that the jelly strength of the pressure-sensitive adhesive layer is not affected, and a certain amount of gelatin can be regarded as “substantially free of gelatin”. When comparing the jelly strength, the difference shall be confirmed taking into account the measurement error.
- Jelly strength refers to a gel prepared by preparing a 1.5% by mass solution of agar, leaving it at 20 ° C for 15 hours, and coagulating the gel for 20 seconds per square centimeter of its surface. Jelly strength (g / cm 2 ) is defined as the maximum weight (g number) that can be withstood.

Further, the problem of sagging of the plaster observed when using a conventional cataplasm containing gelatin is sufficiently reduced. This is because, when the temperature of the outside air becomes high, for example, 30 ° C. or more, the state of gelatin changes and the cohesive force of the plaster decreases, and it can be prevented by substantially not including gelatin.
- a formulation component composition, pH

- purified water For stirring conditions, etc., It may be set appropriately according to the type of the soluble polymer.For example, when easily soluble agar is used, the agar is added to purified water at 65 to 85 ° C and stirred for 5 to 15 minutes to reduce the agar. In minutes to prepare a plaster base.
- the obtained plaster base is applied on a support to form a coating film, and a release sheet is laminated on the coating film.
- This is stored at room temperature for several days, and the water-soluble polymer is sufficiently crosslinked to form a sheet-like hydrogel.
- the thickness of the formed hydrogel sheet is in the range of 0.8 to 1.6 mm. If the film thickness is less than 0.8 mm, the film thickness is too thin, so that sufficient adhesive strength tends not to be obtained. If the film thickness is more than 1.6 mm, the film thickness is too thin, and the film tends to peel off during use. There is a tendency.
- the patch is obtained by cutting it into a predetermined shape.
- the water-soluble polymer in the preparation of the plaster base, as the water-soluble polymer, easily soluble agar, and polyacrylic acid and Z or a salt thereof are contained. preferable.
- the easily soluble agar does not require a high temperature (90 ° C. or higher) for dissolution, the volatile or thermally decomposable component described above can be efficiently incorporated into the patch.
- it is possible to simplify the manufacturing process which requires an apparatus for cooling the solution of agar, energy, time and the like in order to mix volatile or thermally decomposable components.
- the content ratio of each component in the formed sheet-like hydrogel is determined according to the above range. It is easy to put in, and it has a sufficiently excellent usability such as moistness, and has sufficiently reduced oozing of water from the plaster, and has a sufficient adhesive strength to produce a patch. It is possible to get it.
- the patch may have a circular or elliptical shape. Also, holes or cuts may be provided. Further, the shape can be appropriately designed according to the body part where the patch is used. For example, cut it into a facial shape so that it can be attached to the face, , Nose, mouth and chin cut into appropriate shapes.
- a paste base is applied onto a release sheet to form a sheet-like hydrous body, and then the support is laminated to the sheet-like hydrous body.
- the patch of the present invention can be used as a pharmaceutical or a poultice similar thereto, a cooling sheet, a cosmetic or a similar pack, and the like.
- Table 1 shows the components and mixing ratios of the prepared plaster bases. The values in Table 1 are expressed in mass%.
- the pH of the plaster base was 6.4.
- the obtained plaster base was spread on a cloth (25 cm x 25 cm) manufactured by Nippon Vileen Co., Ltd. as a support so as to have a thickness of 1.4 mm. Formed. Further, a product obtained by attaching a release film to the coating film was stored at room temperature to form a sheet-like hydrogel, thereby obtaining a patch which can be shipped as a product.
- the criteria for the patch to be ready for shipment are as follows.
- a plaster base was prepared in the same manner as in Example 1 except that the component compositions shown in Table 1 were used.
- the pH of the plaster base was 6.3 to 6.5.
- Example 1 Using the obtained plaster base, a patch was obtained in the same manner as in Example 1. Table 1 shows the number of days (lead time) from the start of preparation of the plaster base to the point where it can be shipped. Further, the obtained patch was evaluated in the same manner as in Example 1. The results are shown in Table 1.
- a patch was obtained in the same manner as in Example 1 except that gelatin was used in the preparation of the plaster base and the component composition was as shown in Table 2.
- Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Comparative Example 7 Gelatin 1.0 1.2 1 0----Polyacrylic acid------1.5-Polyacrylic acid Na 6.0 3.0 9.0 7.0 1. 0 4.0 10.0 Xanthan gum--0.5-0.5--Polyvinyl 1.1 1.5 1.1 Pyrrolidone
- Example 2 In preparing the plaster base, the same as in Example 1 except that the component compositions shown in Table 2 were used. To give a patch.
- the patches of Examples 1 to 4 had a lead time of 8 to 11 days, whereas the patches of Comparative Examples 4, 6 and 7 had a lead time of 14 to 16 days. From these facts, it was a component that the patches of Examples 1 to 4 were excellent in productivity.
- a composition containing a desired component and having a desired pH is sufficiently excellent in usability such as moist feeling and sufficiently reduces oozing of moisture from the plaster.
