JP5503888B2 - Gel sheet for cosmetic pack - Google Patents

Description

  The present invention relates to a gel sheet for a cosmetic pack to be affixed to the face, arms, legs and the like. More particularly, the present invention relates to a gel pack sheet for skin care using a hydrogel external preparation.

  The gel sheet for cosmetic packs referred to in the present invention is an external preparation for hydrogel pack material containing a large amount of water. This is because water containing medicinal ingredients contained in the gel is exuded by adding a slightly hydrophobic polyhydric alcohol to the gel surface, and the moisture retention effect is obtained by water permeating into the affixed skin. It is a feature.

  Conventionally, Patent Document 1 relates to a sheet-like pack agent, and contains water-soluble polymer, polyhydric alcohol, moisturizing component, crosslinking agent, skin-beautifying component, and water as essential components. Features. Here, gelatin and polyacrylate are described as the water-soluble polymer. Its effect is moderately sticky and moisturizing on the skin, and it is excellent in the stability of the physical properties of the preparation and the safety to the skin. It is.

  Patent Document 2 relates to a sheet-like pack agent for removing sebum, and a layer of a hydrous gel-like composition containing a crosslinked carboxyl group-containing polymer and / or a salt thereof is provided on at least one surface of a support. The layer of the water-containing gel-like composition further contains a polyhydric alcohol. Here, polyacrylic acid, polymethacrylic acid, polyitaconic acid, alginic acid, carboxymethylcellulose, gelatin, pectin, carboxymethylhydroxyethylcellulose, methoxyethylene maleic anhydride copolymer and the like are described as the carboxyl group-containing polymer.

  Patent Document 3 is a sheet-like hydrogel in which a synthetic polymer having a network structure is impregnated with a solution containing at least water, a surfactant, and an oil component and a solution leaching accelerator, and the solution leaching accelerator is polyethylene glycol. In addition, polymers such as glycols such as polypropylene glycol and polyglycerin, and polyhydric alcohols are described.

Japanese Patent Laid-Open No. 08-188527 JP 2002-020257 A JP 2003-183147 A

  However, the water that oozes from the gel sheet is inherently low in viscosity, that is, has a very low viscosity, that is, a so-called free-flowing tactile sensation. The feeling (feeling of moisturizing) felt after use was not sufficient.

  Since the publication of Patent Document 1 describes that more water is efficiently discharged to the outside during use, the concept of liquid leaching is included, but there is no consideration for the state of the effusion. , Usability and usability are insufficient.

  Patent Document 2 discloses a sheet form for removing sebum that can effectively remove excess sebum and dirt, and can remove only the excess sebum while replenishing moisture without causing pain when peeling from the skin. Although it relates to the pack agent, there is no description of liquid exudation and the moisturizing feeling is particularly insufficient.

  In this respect, Patent Document 3 has a high use effect because a solution containing a medicinal component or the like exudes when a nonionic water-soluble polymer as described above is used as a solution exuding agent. However, these nonionic water-soluble polymers have a lower moisture absorption than glycerin, so that the moisture absorption is higher and the solution acts as a solution leaching agent in order to increase the moisture retention of the leached solution. I needed something to do.

  The object of the present invention is to improve the moisture retention of the exuded solution without reducing the exudation property of the solution from the gel surface, solve the so-called dripping property that hangs on clothes during use, and further The present invention provides a gel sheet for a cosmetic pack that can provide a feeling of adhesion and a sufficient effect (moisturizing feeling) when water or the like permeates into the skin applied after use.

  As a result of diligent study, the present inventor has added a suitable amount of hydroxypropyl guar gum obtained by hydroxypropylating guar gum obtained from the fruit of guar, which is a leguminous plant, and polyoxyethylene methyl glucoside as an exudating agent, and a solution from the gel It has been found that the viscosity of the exuded solution increases without lowering the exudability of the liquid, and a remarkable effect is obtained with respect to the improvement of dripping, the feeling of adhesion during use, and the feeling of feeling felt after use (moisturizing feeling). It was.

Thus, according to the present invention,
Synthetic polymer having a network structure, hydroxypropyl guar gum, wetting agent, polyoxyethylene methyl glucoside as an exudating agent, a gel sheet for cosmetic packs containing at least water,
In 100 parts by weight of the gel sheet, hydroxypropyl guar gum is 0.05 to 3 parts by weight,
It is characterized by containing 3 to 12 parts by weight of polyoxyethylene methyl glucoside.

  As described above, the gel sheet for a cosmetic pack of the present invention comprises a sheet-like hydrogel in which a synthetic polymer having a network structure containing hydroxypropyl guar gum is impregnated with an aqueous liquid that oozes on the surface of the gel body. Since the composition contains at least polyoxyethylene methyl glucoside and water as an exuding agent that exudes to the body surface, the moisture retention of the exuded solution is improved and the exudation is performed without reducing the exudability of the solution from the gel. The viscosity of the solution increases, and a remarkable effect is obtained with respect to the improvement of dripping, the feeling of adhesion during use, and the feeling of feeling felt after use (moisturizing feeling).

(Synthetic polymer)
The synthetic polymer is not particularly limited as long as it forms a network structure and can form a gel containing at least water. When the hydrogel is used as a transdermal application in the cosmetic field, a synthetic polymer acceptable in this field can be used. In particular, a synthetic polymer having an affinity for water is used, and among them, a synthetic polymer having an anionic functional group is preferably used. Examples of such synthetic polymers include polymers of polymerizable unsaturated monomers such as acrylic acid and methacrylic acid having a carboxyl group as a functional group, and salts thereof (for example, sodium salt, potassium salt, triglyceride). Ethanolamine salts, etc.), polymers of polymerizable unsaturated monomers such as t-butylacrylamide sulfonic acid having a sulfonic acid group as a functional group, and salts thereof (for example, sodium salts, potassium salts, etc.). . Preferably, sodium polyacrylate is used as the hydrophilic polymer. Moreover, it is preferable that 0.5-35 weight part is contained in 100 weight part of gel sheets as preferable content.

  The synthetic polymer before crosslinking may be partially crosslinked as long as it does not interfere with the production of the sheet-like hydrogel. In view of handling at the time of production, it is preferable to use a synthetic polymer before crosslinking having a weight average molecular weight in the range of 100,000 to 5,000,000.

(Crosslinking agent)
The network structure of the synthetic polymer can be obtained by crosslinking the synthetic polymer before crosslinking. That is, a network structure can be obtained by adding a crosslinking agent to the synthetic polymer before crosslinking and heating as necessary.
Examples of the crosslinking agent include aluminum hydroxide, potassium alum, aluminum sulfate, aluminum glycinate, aluminum acetate, aluminum oxide, aluminum metasilicate, magnesium chloride, calcium hydroxide, calcium carbonate, magnesium aluminate metasilicate, polyethyleneimine, Examples include polyethylene glycol diglycidyl ether, glycerin triglycidyl ether, and triglycidyl isocyanurate.
Moreover, it is preferable that 0.1-5 weight part is contained in 100 weight part of gel sheets for cosmetics packs as preferable content.

(PH adjuster)
In addition, in order to adjust the pH to the optimum value for the action of the cross-linking agent and to ensure the cross-linking, α-hydroxy acids such as tartaric acid, lactic acid and glycolic acid as well as various organic acids such as citric acid and inorganics such as hydrochloric acid An acid may be used as a pH adjuster (acid catalyst).
It is preferable that 0.1-10 weight part is contained in 100 weight part of gel sheets for cosmetics packs as preferable content.
The gel sheet for a cosmetic pack of the present invention may be colored with a pigment or the like, but preferably has a transparent to almost transparent appearance. The term “transparency” as used in the present invention means that it is preferable to ensure transparency to the extent that it can be seen that characters are present when the gel sheet is placed on white fine paper on which 20-point characters are printed in black. In the gel sheet for cosmetic packs of the present invention, a woven or non-woven fabric having a sufficiently large opening ratio is provided inside the gel sheet for the purpose of improving the tear strength and handleability of the gel sheet without impairing the transparency of the gel sheet. It is preferable to make it exist in the thickness direction. In the present invention, a woven or non-woven fabric having a large opening ratio is one having a wide opening ratio (with transparency maintained) so that 20-point characters can be read through the woven or non-woven fabric. Say.
The gel sheet for cosmetic packs having a transparent to almost transparent appearance of the present invention has an excellent appearance effect that the effect of improving the skin can be seen through the adhered gel sheet and that it can be accurately applied to a predetermined site.
As the thickness of the gel sheet for cosmetic packs of the present invention, the whole may be uniform or partially different in thickness, but in order to ensure adhesion, transparency and strength, A thickness of 3 mm is preferred. If it is less than 0.1 mm, the strength of the gel sheet is weak, and if it exceeds 3 mm, the gel sheet may be too heavy and lack adhesion. If the entire gel sheet is not thick, it is possible to partially increase the gel sheet to a thickness of up to 6 mm.

(Hydroxypropyl guar gum)
Hydroxypropyl guar gum used in the present invention is a method of reacting sodium hydroxide and propylene oxide using guar gum, which is a natural water-soluble polymer polysaccharide, contained in the seed endosperm part of guar, which is a leguminous plant, as a raw material. Is a nonionic polymer obtained by substituting a hydroxyl group with a hydroxypropyl group.
Other cellulose ethers used as water-soluble thickeners, polysaccharides such as cellulose, guar gum, cationized guar gum, starch, xanthan gum and their derivatives, etc. for improving the dripping property of aqueous solution leached from the gel sheet It seems that it can be solved by increasing the viscosity of water etc. in the hydrogel by adding it, but the water retention of the gel itself will increase, and the exudation of the solution containing chemical components from the gel will be suppressed On the other hand, the viscosity of the exuded solution did not increase, and the tactile sensation remained free, and the above-mentioned improvement effect was not sufficient.

  The hydroxypropyl group substitution degree in hydroxypropyl guar gum is preferably 0.4 to 1.2. More preferably, 0.6 to 1.0 is more effective.

  Hydroxypropyl guar gum is contained in an amount of 0.05 to 3 parts by weight in 100 parts by weight of the gel sheet for cosmetic packs. When the hydroxypropyl guar gum is less than 0.05 parts by weight in 100 parts by weight of the gel sheet for cosmetic packs, the dripping property is not improved and the adhesion feeling in use is not improved as compared with the one not containing hydroxypropyl guar gum. The moisturizing feeling felt after use is also reduced. When hydroxypropyl guar gum is contained in an amount exceeding 3 parts by weight in 100 parts by weight of the gel sheet for cosmetic packs, a sticky feeling appears strongly, which is not preferable because the feeling of use during use deteriorates. More preferably, the hydroxypropyl guar gum is contained in 0.1 to 2 parts by weight, optimally 0.2 to 1 part by weight, in 100 parts by weight of the gel sheet for cosmetic packs.

(Exudate)
The exuding agent is an agent used for effectively exuding the solution in the hydrogel to the hydrogel surface. Also called a solution leaching accelerator. For example, water in the hydrogel can be effectively discharged by blending a substance having a certain degree of hydrophobicity while being hydrophilic.
In the present invention, polyoxyethylene methyl glucoside, which is a nonionic water-soluble polymer, is used.

  As for polyoxyethylene methyl glucoside, 3-12 weight part is preferable in 100 weight part of gel sheets for cosmetics packs. If the amount of polyoxyethylene methyl glucoside is less than 3 parts by weight in 100 parts by weight of the gel sheet for cosmetic packs, the adhesion and effect are not preferred. When polyoxyethylene methyl glucoside exceeds 12 parts by weight in 100 parts by weight of the gel sheet for cosmetic packs, the amount of exudation is too large and the liquid dripping property is not preferable. A more preferred range is 6 to 10 parts by weight.

  Polyoxyethylene methyl glucoside is a nonionic water-soluble polymer having a specific moisture absorption of 70, where the moisture absorption of glycerol is 100. High specific moisture absorption and high water retention ability of nonionic water-soluble polymers, but has the ability to exude the solution in the hydrogel to the hydrogel surface, further improving the moisturizing and moisturizing effect of the exuded solution To do.

(Wetting agent)
Examples of the wetting agent include ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, glycerin, diglycerin, isopropylene glycol, 1,3-butylene glycol, sorbitol, malbitol, trehalose, raffinose, xylitol, mannitol. , Hyaluronic acid and its salts, various derivatives such as trehalose and raffinose, trimethylglycine, cyclodextrin, glycols such as hyaluronic acid and its salts, polyhydric alcohols and polysaccharides. These can be used alone or in admixture of two or more.
It is preferable that 1-30 weight part is contained in 100 weight part of gel sheets for cosmetics packs as preferable content.

  The compounding amount of these components cannot be defined unconditionally because the amount of the active ingredient varies depending on the material, but is generally preferably 0.001 to 80% by mass relative to the mass of the gel sheet for cosmetic packs, 0.05 More preferably, it is -30 mass%.

(Production method)
For example, to a mixture obtained by mixing at least a synthetic polymer, hydroxypropyl guar gum, a wetting agent, and water, a cross-linking agent and polyoxyethylene methyl glucoside as an exuding agent are added and mixed to react. The method can be adopted. Preferably, a production method characterized by adding a pH adjusting agent (acid catalyst) to adjust the pH of the mixed solution to 4 to 7 and reacting it can be adopted.
What is important here is that hydroxypropyl guar gum is previously added to the synthetic polymer and wetting agent, hydroxypropyl guar gum is dissolved, and then a cross-linking agent and polyoxyethylene methyl glucoside as an exuding agent are added. It is. In other words, since polyoxyethylene methyl glucoside is liquid at room temperature, there is no problem, but it is desirable to add hydroxypropyl guar gum before gel formation. If hydroxypropyl guar gum is added after making a gel, the number of steps increases, so the cost is high and the pack cannot be made homogeneous. That is, when hydroxypropyl guar gum is added after the gel has been prepared, it is difficult to uniformly disperse the hydroxypropyl guar gum that is a solid on the gel surface. For example, when it is added as an aqueous solution, it is highly viscous. It is difficult to disperse uniformly. On the other hand, even if a low-concentration aqueous solution is prepared and added in order to reduce the viscosity, the characteristics (usability and effect) required by excess water cannot be obtained. In addition, when it cannot be uniformly dispersed, the viscosity of the exudate varies, and it is not preferable because the required characteristics cannot be obtained, such as partial peeling or local moisturizing effect.

For example, 0.5 to 35 parts by weight of the synthetic polymer, preferably 1 to 30 parts by weight, more preferably 2 to 25 parts by weight, and 0.05 to 3 parts by weight of hydroxypropyl guar gum, preferably 0.1 to A mixture obtained by mixing at least 2 parts by weight, more preferably 0.2 to 1 part by weight, 1 to 30 parts by weight of a wetting agent, preferably 2 to 20 parts by weight, and water is further added to the crosslinking agent. 0.1 to 5 parts by weight, preferably 0.5 to 2 parts by weight, and 3 to 12 parts by weight, preferably 6 to 12 parts by weight of polyoxyethylene methyl glucoside as an exuding agent, and mixed to react. It is made to make it the manufacturing method of the gel sheet for cosmetics packs characterized by the above-mentioned.
Here, more preferably, a pH adjusting agent (acid catalyst) is added in an amount of 0.1 to 10 parts by weight, preferably 1 to 5 parts by weight, and the pH of the mixed solution is adjusted to 4 to 7 to react. It is made to make it the manufacturing method of the gel sheet for cosmetics packs characterized by the above-mentioned.

  In addition, it is preferable to add 60 to 97 parts by weight of water in total, preferably 70 to 95 parts by weight. A part of the water is preferably added to the mixture of the crosslinking agent and the exuding agent and added as a mixed solution.

  Hereinafter, although an example and a comparative example explain the present invention, the present invention is not limited to this.

(Example)
Using the gel-forming composition shown in the following table, gel sheets of Examples and Comparative Examples used for cosmetic packs were prepared according to the following procedure. A wetting agent was added to the synthetic polymer and hydroxypropyl guar gum (HP guar gum) or other thickening agent, and the medicinal components and water were further added and kneaded until uniform.
To this mixture, polyoxyethylene methyl glucoside as an exuding agent, further adding a cross-linking agent and water to a well-dispersed slurry, and then adding a pH adjusting agent (acid catalyst) to make a total of 100 parts, fully kneaded and stirred did. Next, spacers with a thickness of 1 mm are placed at the four corners of a 38 μm-thick PET film (polyethylene terephthalate film) placed on a smooth glass plate, and an appropriate amount of the above composition is poured into the central portion immediately after mixing, and the basis weight is set. A 17 g / m ² nylon knitted fabric (Tricot half) and another 38 μm-thick PET film were layered, sandwiched between glass plates and allowed to stand for 24 hours to obtain a gel sheet having a thickness of 1 mm. This gel sheet was cut into 5 cm × 5 cm to obtain a sample for evaluation.

The amount of liquid leaching from the gel sheet was measured as follows.
The gel sheet is taken out from the bag immediately before the measurement, the PET film on both sides is peeled off, the weight (a) is measured, and then the PET film is pasted only on one side. Two glass plates (100 × 100 mm, 3 mm thick) and filter paper (5A diameter 150 mm circle made by Advantech) are prepared, and the weight (b) of the filter paper is measured and placed on one glass plate. A gel sheet is attached to the center of the filter paper with the gel surface facing down, and another glass plate is placed on the gel sheet and allowed to stand for 10 minutes. Thereafter, the PET film on the glass plate and the gel sheet is removed, the gel is further removed, and the weight (c) of only the circular filter paper is measured. From the difference from the filter paper weight measured in advance, the weight of the exuded liquid is calculated. calculate. This liquid amount is expressed as a ratio with respect to the original gel weight and is defined as an exudation amount ((c−b) / a). As the measured value, an average value obtained by performing the same test on three gels is used.
If the amount of exudation is small, the adhesion to the skin will be reduced, so it will be easily peeled off during use, and the amount of liquid that penetrates the skin will be small, so the effect of moisturizing will be insufficient. Since it falls or excessive liquid drips (drip) and adheres to clothes etc., the preferable range of the amount of exudation is 20-35 (%).

[Evaluation as a pack agent]
After the gel sheet formed as described above is applied to the cheeks of 10 female subjects with the upper body raised and evaluated for adhesion and liquid dripping when left for 20 minutes, and after peeling off after 20 minutes The moisturizing feeling of the skin condition was expressed in the following five stages 1 to 5, evaluated as the usability and effect as a pack agent, and the evaluation result was obtained with the total score of all subjects. Therefore, these evaluation values indicate the magnitude of performance and effect (full score of 50 points). The results are shown in the table.

Feeling of effect (moisturizing feeling) Evaluation 5: I feel that the skin is remarkably moisturized.
4: I feel that the skin is moisturized.
3: The skin feels slightly moisturized.
2: The skin feels slightly moisturized.
1: The effect is not felt.

Usability (Liquid Drip) Evaluation 5: No dripping at all.
4: There is slight dripping.
3: There is a little dripping.
2: There is much dripping.
1: Too much liquid dripping, so that the exuded liquid adheres to clothes.

Usability (Adhesiveness) Evaluation 5: The skin is completely adhered and there is no deviation.
4: Almost in close contact with the skin, with little deviation.
3: There is a part that is not in close contact with the skin, and there is a slight deviation.
2: It is difficult to adhere to the skin and there are many deviations.
1: The displacement falls greatly.

From Table 1, regardless of whether the medicinal component is aqueous or oily, the gel sheets of Examples 1 to 6 have an appropriate amount of exudation compared to Comparative Example 1 in which no polyoxyethylene methyl glucoside is added, and usability (liquid dripping). Property, adhesion) and effect (moisturizing feeling) are excellent. In the case of Comparative Example 2 in which the polyoxyethylene methyl glucoside is 15 parts by weight with respect to 100 parts by weight of the gel sheet for cosmetic packs, since the polyoxyethylene methyl glucoside is too much, the amount of exudation is excessive and dripping. Inadequate in terms of adhesion.
In the case of Comparative Examples 3 to 6 of guar gum, cationized guar gum, xanthan gum and hydroxyethyl cellulose as other thickeners in place of hydroxypropyl guar gum, the exudation amount is appropriate, but the dripping property and adhesion are insufficient. , Lack of moisturizing feeling. Moreover, in the case of the comparative example 7 of Na hyaluronate as another thickening agent, although the dripping property is good, the amount of exudation is insufficient, the adhesion is lowered, and the moisturizing feeling is insufficient.

  Moreover, in the case of the comparative example 8 which HP guar gum exceeds 3 weight part with respect to 100 weight part of the gel sheet for cosmetics packs, a sticky feeling appeared strongly and the usability at the time of use deteriorated. Moreover, in the case of the comparative example 9 whose HP guar gum is less than 0.05 part by weight with respect to 100 parts by weight of the entire gel sheet for cosmetic packs, the amount of exudation is appropriate because the amount of HP guar gum is too small. Insufficient performance and lack of effectiveness.

INDUSTRIAL APPLICABILITY The present invention is useful as a gel pack sheet for skin care using a hydrogel external preparation, which can be used as a gel sheet for a cosmetic pack that can be affixed to the face, arms, feet, and the like.
