Each composition for constituting the above-described effervescent solid formulation is powdered for freeze drying or spray drying, and these may be mixed to prepare a mixed powder formulation or granule formulation, or may be prepared in a tablet formulation through tableting.

Freeze-drying or spray-drying processes may have different conditions depending on each composition, and a known method is used. At this time, each powder has an average particle diameter of 0.1 to 1000 μm in order to increase the ease of mixing and solubility in water.

In the case of a mixed powder formulation or a granular formulation, carbonates, organic acids, cosmetically active ingredients, and additives may be prepared in powder form, respectively, and then mixed to form a single granule, or simply mixed to form a mixed powder.

In the case of tablets, each powder may be added to a tablet press and then tableted to be prepared, and at this time, an excipient may be further included for molding. Excipients such as mannitol and lactose may be used as the excipient. In the case of a tablet, the shape may be a hexahedron, a coin type, a spherical shape, an elliptical sphere, or a cylindrical shape.

In the case of a tablet formulation according to another embodiment of the present invention, 15 to 150 parts by weight of a carbonate powder, 50 to 200 parts by weight of an organic acid, 0.1 to 5 parts by weight of an additive, and 1 to 20 parts by weight of an excipient are included based on 1 part by weight of the cosmetically active ingredient. do.

In the mask pack kit of the present invention, the effervescent solid formulation is designed to contain the amount of cosmetic active ingredients required for skin care once, so that it is easy to carry and when used (massage), only the effervescent solid formulation (in the case of a tablet) is taken out and used conveniently. I can. As a result, problems or uneconomical problems caused by use of less than an appropriate amount or use of an excessive amount can be solved.

A single use amount of the effervescent solid formulation may be about 3g to 30g or 7 to 20g in the case of a mixed powder and granule formulation. In the case of tablets, it may be about 5 to 50 g or 8 to 30 g in consideration of the content of the excipient.

The foamable solid preparation is foamed by the reaction of carbonate and organic acid with water (i.e., purified water), and cosmetically active ingredients and additives exist inside the aqueous phase, and the cosmetically active ingredients and additives are on the surface and inside of the sheet-shaped support. Penetrates the pores.

The sheet-shaped support may include a material selected from the group consisting of nonwoven fabric, cotton, hydrogel, biocellulose, and combinations thereof. These can be used alone or in combination of two or more, and can be produced as single-layer or multi-layered sheets. According to one embodiment of the present invention, the sheet-like support may be 100% biocellulose.

The sheet-like support is manufactured in a dry state for storage and distribution, and as shown in FIG. 1, biocellulose can be manufactured and used in a compressed shape. The compressed shape may be a hexahedral, spherical, elliptical, or irregular shape having a diameter of 2.5 to 4 cm. In the case of non-woven fabric, cotton, or hydrogel, it is not easy to press, so it can be used in a folded form.

Such a sheet-like support should be converted into a wet sheet after swelling by the addition of a foamable solid preparation and water, adhere well to the skin, and should not cause damage such as tearing during use.To this end, the sheet-like support must be at least 1.5 mm to 2.7 mm thick and 1 g It should have a weight of to 3g. If the thickness is too thin below the above range, there is a problem that the sheet is too sticky after swelling and it is difficult to unfold when used.If the thickness is too thick, the sheet becomes too thick and there is a problem that the adhesion decreases when attached to the skin, so it is appropriately adjusted within the above range.

The sheet-like support must be easily restored to its original state when a certain amount of water is added in the dry state, and must be convertible into a wet sheet that can be used and attached directly to the skin. This can be achieved when the sheet has the thickness and weight of the sheet and the size of the diameter after compression, and should have a moisture content represented by Equation 1 below.

The moisture content refers to the content of moisture remaining in the sheet. As the moisture content is lower, there is no occurrence of bacteria or viruses, and thus, a moisture content rate of less than a predetermined range may be regarded as a value indicating a dried state at a level in which no preservative is required. On the other hand, as the moisture content in the sheet-like support decreases, the volume of the sheet decreases. With this concept, in the present invention, it is possible to manufacture and maintain a compressed form by adjusting the moisture content of the sheet-like support. In addition, the moisture content is adjusted for quick conversion when converting to a wet sheet after adding water later.

The moisture content of the sheet-like support according to the present invention is calculated by Equation 1 below.

[Equation 1]

Moisture content (% by weight) = (a-b) / a x 100

(In the above formula, a is the weight of the sheet-shaped support to be packaged, and d is the weight measured after completely removing moisture by leaving the sheet-shaped support to stand at a drying oven temperature of 100° C. for 24 hours, and the moisture content is an average of 50 samples. It's a shame.)

Based on Equation 1, the moisture content of the sheet-like support according to the present invention is 15% by weight or less, and for use after swelling in water, it has a value of at least 1.5% by weight and 2% by weight. If the value exceeds the above range, there may be a concern about bacterial growth due to moisture. Conversely, if it is less than the above range, a lot of water and time are required for swelling, and there is a risk of contamination before use of the wet sheet.

Another sheet-like support according to a preferred embodiment of the present invention may be made of 100% biocellulose, especially pure biocellulose. The production of such a 100% biocellulose sheet-like support is not particularly limited in the present invention, and may be achieved by a known method for producing a sheet.

Biocellulose is obtained by fermenting a natural substance, and can be produced directly or purchased commercially and used. In particular, in order to reduce costs, a residue remaining after manufacturing a mask sheet made of only biocellulose may be used.

The raw material of the bio-cellulose is not particularly limited in the present invention, and any known material that is harmless to the human body, especially used in cosmetics or medical fields without skin irritation, may be used. For example, it may be coconut pulp, watermelon, sugar cane, tropical fruit, or a pulverized product thereof, and preferably coconut pulp may be used.

As an example, the production of bio-cellulose using coconut flesh is as follows.

에서 5~10일간 정치 혼합 배양 또는 교반 혼합 배양하면 불투명한 겔이 얻는다.First, after adding microorganisms to the coconut pulp, 20-40

An opaque gel is obtained by static mixing culture or stirring mixing culture for 5-10 days.

The microorganisms for use either or, the production efficiency is selected from acetonitrile bakteo (Acetobacter), A rayijo Away (Rhizobium) genus Agrobacterium bakteo (Agrobacterium), program also Manas in (Pseudomanas), buy Sina in (Sarcina) It is also possible to mix and cultivate several kinds of microorganisms.

Next, the opaque gel is washed and dried to form a sheet.

After cutting the biocellulose sheet, it is manufactured into a pressed sheet-like support by performing a compression process of pressing at a predetermined pressure using a hand or a mechanical device.

Preferably, the compression process can be performed by inserting a biocellulose sheet into a cylindrical mold and then pushing a compression mechanism, or by inserting a dried biocellulose sheet into a spherical mold and making it through compression of the mold. . At this time, the biocellulose sheet is compressed and lumped by a pressing mechanism, and the moisture remaining after the drying process is further removed, so that it is possible to manufacture in a state where the moisture content is controlled. The pressing process can be performed at room temperature, and the temperature inside the mold is adjusted to 30 to 45° C. in order to more easily control the moisture content. If the temperature inside the cylinder is too high, bio-cellulose sticks together and cannot be used. Conversely, when the temperature is low, a high pressure must be applied to remove moisture, so there is a risk of damage such as tearing of the sheet. At this time, the pressing time is performed briefly for 10 seconds to 2 minutes, preferably 20 seconds to 1 minute 30 seconds .

On the other hand, the sheet-like support in a dried state generates bubbles due to the use of the foamable solid preparation, so that the cosmetic active ingredient penetrates faster, and has a faster swelling rate compared to the use of the same amount of water.

Suitable swelling degrees for adhesion to the skin and use have at least 85%, 85-95%, 86-94%, 89-92% by weight. If the swelling degree is less than the above range, it means that the sheet-like support does not sufficiently swell, and if it exceeds the above range, there is a feeling of foreign body due to weight when attached to the skin, especially the face, and the active ingredient may flow down. Delivery may not be sufficient.

The sheet-like support of the present invention can achieve the degree of swelling within 2 minutes due to the use of a foamable solid preparation.

In the mask pack kit according to the present invention, water is used for the swelling of the sheet-like support and dissolution of the foamable solid preparation, and in this case, it is preferable to use purified water.

When the purified water is added in an appropriate amount from the outside, or when the foamable solid preparation is used as the first agent and the sheet-like support is used as the second agent, it can be used as a third agent separated from them.

The amount of purified water is used in an amount capable of sufficiently swelling the sheet-like support and dissolving the effervescent solid preparation sufficiently, and is preferably used in the range of 15 to 40 ml when used once.

The effervescent solid preparation and the cosmetic active ingredient as described above may be packaged in a pouch or the like to prepare a skin care kit.

In the skin care kit, a first pouch including an effervescent solid preparation and a second pouch including a sheet-like support are accommodated in a container.

The first pouch and the second pouch may be separated separately or may be connected to each other so that they can be separated from each other by a perforation line.

Hereinafter, the configuration of the kit will be described in detail.

The container material may be made of plastic, glass, and paper, and paper is used in consideration of being disposable.

The shape of the container is not particularly limited in the present invention, and has a cylindrical, cup-shaped, square, rectangular, trapezoidal, polygonal, or irregular three-dimensional shape.

According to a preferred embodiment, the container may be cup-shaped, and at this time, the upper part of the container is equipped with a lid to allow opening and closing thereof. The lid may be made of plastic or paper, and a plastic material is used for convenience in use. The lid has a locking protrusion so as to be inserted into the opening of the container to be coupled, and has a design similar to the lid of a disposable coffee cup.

According to another preferred embodiment, the container may be cylindrical and may be made of plastic or paper. In this case, the lid may have a structure in which a band formed with a hollow silicone treatment is formed on the locking jaw or inside the lid, or a male and female thread is mounted therein.

A cover in the form of a sticker, film or sheet is additionally formed on the top of the container to protect the first pouch and the second pouch. The cover may be a plastic film in which an aluminum deposition layer is formed on the lower side, and is attached by an adhesive method, a hot melt method, or a thermocompression method.

If necessary, the inside of the container may further include a bar-shaped mixing means made of a plastic material such as polystyrene, polyethylene, or polypropylene to aid in swelling of the sheet-like support and dissolution of the foamable solid preparation. The mixing means may be inserted into the container or attached to one of the inner and outer sides thereof.

The first pouch and the second pouch may be made of a film material such as PSP, EPS (Expanded Polystyrene), PP, etc., respectively, and the foamable solid preparation and the sheet-like support are added and then sealed through heat bonding. If necessary, for sterilization, each pouch is subjected to a gamma treatment process.

The foamable solid preparation and sheet-type support that are respectively injected into the first pouch and the second pouch can be packaged in a variety of ways, and an individual packaging method including only one use amount in one pouch, a plurality of foamable solid preparations, and a sheet-type support are provided. Individually packaged blister packaging methods, or 2 or more, 10 or more, 30 or more bulk packaging methods may be used. In the blister packaging method, the foamed solid preparation and the sheet-shaped support may be divided and packaged in one tray, or each of them may be divided and packaged in a separate tray.

The size and shape of the first pouch and the second pouch are not particularly limited, and any one that can safely accommodate the foamable solid preparation and the sheet-like support may be used. For example, it may be rectangular, square, circular, or stick-shaped.

2 shows a mask pack kit according to an embodiment of the present invention, a container 10 provided with a lid 12 and a lid 14 is prepared, and a foamable solid formulation 22 is inserted therein. The first pouch 20 and the second pouch 30 into which the compressed sheet-like support 32 is inserted may be inserted.

3 is a view showing an example of the individual packaging of the mask pack kit of the present invention, a foamable solid preparation 122 is inserted into the first pouch 50, the sheet-shaped support body compressed inside the second pouch 60 ( 132 is inserted, and at this time, the first pouch and the second pouch 50 and 60 may be manufactured in a shape connected to each other.

4 is a view showing an example of the bulk packaging of the mask pack kit of the present invention, a foamable solid formulation 150 is filled in the inside of the cylindrical first container 150 provided with a lid 152, and a lid ( The sheet-shaped support 232 compressed into the cylindrical second container 160 provided with 162 may be inserted.

In addition, the disposable skin care kit of the present invention may further include a third pouch containing water for swelling of the sheet-like support and dissolving the effervescent solid preparation.

At this time, the material and shape of the third pouch are as described above, and 15 to 40 ml of purified water may be sealed for one use.

A method of using the mask pack according to the present invention will be described with reference to the drawings. 5 is a view showing a method of using the mask pack kit of FIG. 2.

First, the first pouch and the second pouch are cut, respectively, and the foamable solid preparation 22 and the sheet-like support 32 present therein are put into the container 10.

Water (or purified water) is added thereto to dissolve the foamable solid preparation 22 to generate air bubbles, and to cause swelling of the sheet-like support 32 to produce a mask pack.

Water may be added in an amount calculated for dissolving the foamable solid preparation 22 and swelling the sheet-like support 32, and in the case of making a third pouch, water is added to the container by cutting it.

Due to the dissolution of the effervescent solid formulation 22, the cosmetically active ingredient contained therein penetrates inside the swollen sheet-like support. The penetration may reach the surface and inner pores of the sheet-like support, and in particular, as the sheet-like support is used in a dried form, a greater amount of the cosmetically active ingredient can be penetrated.

The reaction between the carbonate and organic acid present in the effervescent solid formulation occurs due to the water introduced into the container, and bubbles are violently generated by this reaction. The swelling rate of the sheet-like support can be increased by the air bubbles.

The high swelling rate means that the mask sheet can be used immediately with only a small amount of time. If left unattended for a long period of time, it is desirable to have a fast swelling rate because the probability of introducing pollutants such as dust increases.

The fast swelling rate of the sheet-like support alone cannot guarantee the effective effect on the skin when using a mask pack, and it is advantageous to support the cosmetic active ingredient in a high content if possible. Accordingly, the opportunity of contact between the cosmetically active ingredient and the sheet-like support may be increased by the air bubbles, thereby further increasing the penetration power and penetration rate of the cosmetically active ingredient into the sheet-shaped support, and a larger amount of the cosmetically active ingredient may be supported. .

In particular, when biocellulose is used as a sheet-like support, a cosmetically active ingredient can be supported in a larger amount than that of a sheet made of a nonwoven or cotton material, and the amount of support can be further increased as the moisture content in the sheet-like support decreases.

In addition, by repeatedly pressing the sheet-like support using the rod-shaped mixing means 16, swelling occurs evenly, and the penetration force and penetration rate can be further increased.

Next, the prepared mask pack is extracted from the container, attached to the skin, and left for 10 to 30 minutes.

After a certain period of time, the mask pack is removed from the skin, and the cosmetic active ingredients contained in the mask pack can be effectively delivered to the skin. The mask pack according to the present invention can induce freshness, fun, and interest by allowing the user to directly participate in the manufacture of the pack.

[Example]

Hereinafter, examples, etc. will be described in detail to aid understanding of the present invention. However, the embodiments according to the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the following examples.

Example 1

(1) Preparation of effervescent solid formulation

5% by weight of vitamin C, 50% by weight of citric acid, and 20% by weight of mannitol were mixed, and then 25% by weight of sodium bicarbonate was added to prepare a mixed powder.

The mixed powder was tableted with a single tablet press at a temperature of 23° C. and a relative humidity of 25% to prepare a circular foamable solid preparation having a weight of 1000 mg, a diameter of 1.5 cm, and a thickness of 3 mm.

(2) Preparation of dry biocellulose sheet

The biocellulose block made by fermenting coconut was sliced into a thickness of 1.5 mm to 3.5 mm and washed. The washed biocellulose slices were sterilized at 125° C. for 25 minutes, and after injection, they were pressed so that the openings of the face and eyes and the slit of the nose were formed to prepare a 2.0mm, 1.7g sheet.

The prepared biocellulose sheet was dried at 100° C. for 10 minutes.

Then, the obtained sheet was put into a cylindrical mold and then a compression process was performed at 40° C. for 30 seconds to prepare a dry biocellulose sheet compressed into a coin shape. At this time, the prepared dry biocellulose sheet had a moisture content of 4.3% by weight according to Equation 1.

(3) manufacturing mask sheet

After the foamable solid preparation and the compressed dry biocellulose sheet were put into a transparent container, 40 ml of distilled water was added. The distilled water was converted into a yellow aqueous solution according to the dissolution of the effervescent solid preparation, and after allowing to stand for 2 minutes, a mask sheet made of biocellulose material having a pale yellow color was recovered.

Example 2

A mask sheet was prepared in the same manner as in Example 1, except that a nonwoven fabric was used instead of a dry biocellulose sheet as a sheet-like support.

Comparative Example 1

A mask sheet was prepared in the same manner as in Example 1, but a mask sheet was prepared by adding 50 mg of vitamin c, not an effervescent solid formulation.

Comparative Example 2

A mask sheet was prepared in the same manner as in Comparative Example 1, except that a nonwoven fabric was used instead of the dry biocellulose sheet as a sheet-like support.

Test Example 1

(1) Appearance: Color comparison

Vitamin c is yellow, so the mask packs prepared in Examples and Comparative Examples are pale yellow as a whole. At this time, the higher the content of vitamin c impregnated (ie, penetrated) in the sheet-like support, the darker the yellow color is.

In the case of the combination of the foamable solid formulation of Example 1 and the biocellulose sheet, the darkest yellow color was shown, and it was confirmed that the mask pack of Example 2, Comparative Example 1, and Comparative Example 2 gradually showed pale yellow color. This result means that the mask pack of Example 1 contains the highest content of vitamin c.

(2) degree of absorption of cosmetics

After using the mask sheets prepared in Examples and Comparative Examples for 30 female subjects in their 20s to 30s, the effect was evaluated according to the following evaluation criteria for feeling of use, moisturizing effect, brightening effect after use, and overall satisfaction. Is shown in Table 1 below.

The feeling of use refers to the feeling that the mask sheet adheres well to the face, the moisturizing effect refers to the moist feeling of the skin after use, and the brightening effect refers to the instantaneous brightening of the complexion. Comprehensive satisfaction was evaluated in consideration of their satisfaction.

<Evaluation criteria>

5 points: very good

4 points: excellent

3: good

2: dissatisfied

1: not available

Example 1 Example 2 Comparative Example 1 Comparative Example 2 Feeling 4.5 3.5 2.1 1.2 Moisturizing effect 4.3 3.0 2.8 1.1 Brightening effect after use 4.0 3.2 2.9 1.0 Overall satisfaction 4.27 3.23 1.93 1.1

Referring to Table 1, as in Example 1, when the foamable solid preparation and the dry biocellulose sheet were used together, the evaluation values were the best. In comparison, it can be seen that the effect is low when purified water rather than foaming is used as in Comparative Example 1.

In addition, comparing Example 1 and Example 2, the effect was higher when using a biocellulose sheet rather than a nonwoven fabric, which is due to the result that more vitamin c is impregnated into the biocellulose.

As in Comparative Example 2, in the case of the combination of purified water and the nonwoven fabric, it can be seen that water flows down into the nonwoven fabric and thus the feeling of use is very reduced.

(3) degree of swelling

As a result of measuring the swelling degree of the mask packs of Example 1 and Comparative Example 1 according to Equation 2, the swelling degree of the mask pack of Example 1 using the effervescent solid formulation was 97% by weight, compared with the non-expanded solid formulation The swelling degree of the mask pack of Example 1 was measured to be 71% by weight.

This low degree of swelling consequently makes it difficult for vitamin c to penetrate into the biocellulose sheet, which means that the efficacy and effect of vitamin c in the mask pack cannot be expected as much.
