Description

  The present invention relates to a sheet-like cosmetic containing an alkaligenes-producing polysaccharide.

Conventionally, as a sheet-like cosmetic used by being applied to the skin, a gel-like cosmetic ingredient containing a component having a moisturizing action and a whitening effect is applied or impregnated on a sheet-like support. . These make the sheet-like support have the strength and shape-retaining property as a sheet cosmetic, infiltrate the active ingredient in the cosmetic ingredients to be applied or impregnated into the skin, and further adjust the stratum corneum to enhance the moisture retention power of the skin. It is used with the expectation of the effect of improving.
In general, the sheet-like cosmetic is a method in which components are allowed to permeate the skin for 5 to 30 minutes. As the sheet material, a woven fabric or a nonwoven fabric is generally used, and a gelling component is applied or impregnated in order to prevent the makeup component from sagging. As the material of the gel component to be applied or impregnated on these substrates, natural polymer materials such as collagen, alginic acid and pullulan, and synthetic polymer materials such as crosslinked polyacrylate are used.

  Patent Document 1 includes one or more selected from among carboxyvinyl polymer, acrylic acid methacrylic acid long-chain alkyl (10 to 30 carbon atoms), xanthan gum, and lemon, pearl, prune and carrot. Sheet-like pack cosmetics that are excellent in feeling of use such as adhesion and moisturizing effect by impregnating a non-woven fabric with a gel-like cosmetic composition containing one or more plant extracts. A method for providing a fee is disclosed. In Patent Document 2, by using a gel formed from xanthan gum, locust bean gum, a water-soluble solvent, and water, it is excellent in shape retention at high temperature and has a high absorption effect such as moisture on the skin, that is, moist. A sheet-like pack agent that imparts a feeling is disclosed. Patent Document 3 discloses a method of imparting a moist feeling to the skin by using a specific alkylene oxide derivative, in addition to its moisturizing action, and release from a gel-like base. However, these hydrophilic gelling components have many hydrogen bonding sites and have problems such as stickiness to the touch. In particular, when placed on the skin for a long time, a large amount of the sheet component remains on the skin, resulting in a problem that the feeling of feeling is very poor.

  A method for improving the problem that the sheet component remains on the skin is also disclosed. In Patent Document 4, a copolymer of acrylamide and a crosslinkable monomer as a sticking agent, selected from the group consisting of polyacrylamide crosslinked with an epoxy crosslinking agent, carrageenan, hyaluronic acid and its salt, deoxyribonucleic acid and its salt 1 or 2 or more selected from the group consisting of glycerin, diglycerin, polyethylene glycol, 1,3-butylene glycol, sorbitol, and malbit as a wetting agent. After filling a 0.1 to 3 mm recess with a liquid material consisting of a raw material of a sticky agent, a wetting agent, a physiologically active ingredient, and water, by applying heat and cooling, it is solidified by cooling. A method is disclosed that fits the shape, has excellent adhesion to the skin, and does not leave the sheet component on the skin. In Patent Document 5, an ether-based thermosensitive polymer that undergoes dehydration with increasing temperature and collagen whose conformation changes with increasing temperature or gelatin that is a degradation product thereof are used in combination in the gel. Disclosed is a method that can control the amount of release of an active ingredient such as a medicinal ingredient that is contained, and that can maintain an appropriate shape strength. These methods have the advantage that the shape retention is improved and the moisture and sheet components are not excessively released onto the skin, but there are problems such as inhibiting the permeability of the active ingredients. In addition, it is also known to add adhesive components such as polyvinylpyrrolidone, polyvinyl alcohol, and polyacrylate to prevent it from remaining on the skin, but problems such as inhibiting the penetration of active ingredients was there.

Sheet cosmetics are used with the expectation that the active ingredients in the cosmetic ingredients to be applied or impregnated will penetrate into the skin, and the stratum corneum is prepared to improve the moisture retention of the skin. There is also a problem of reducing the strength of the agent. In particular, when the active ingredient is a salt compound, the gel viscosity is lowered and further a precipitate may be formed.
As a countermeasure, Patent Document 6 discloses a method for preventing a decrease in viscosity by blending sclerotium gum. Patent Document 7 discloses a method of blending one or more selected from hyaluronic acid or a salt thereof, acetylated hyaluronic acid or a salt thereof, and xanthan gum. However, it is insufficient to prevent a decrease in gel viscosity, and has not yet improved the feeling of use such as stickiness and creaking caused by active ingredients and salt compounds.

  A method of blending a moisturizer for the purpose of imparting moisture to the skin and preparing the stratum corneum as an active ingredient is also known. Although a method of blending is disclosed, there are problems that salts and hydrophilic polymers have many hydrogen bonding sites, and stickiness after taking a sheet mask becomes strong.

JP 2002-114664 A Japanese Patent No. 2761936 JP 2005-225837 A JP-A-11-269031 Japanese Patent No. 5653573 JP 2002-293714 A Japanese Patent No. 4781464 JP 2010-90059 A

  The present invention has been made in view of the above-described conventional situation, and after the sheet-like cosmetic has been placed on the skin for a long time, there is little stickiness even after the cosmetic is taken, and the cosmetic It aims at providing the sheet-like cosmetic which does not inhibit the penetration | invasion to the skin of the active ingredient contained in the cosmetic ingredient.

  The inventor of the present invention makes long use of a sheet-like cosmetic by blending an alkali-genes-producing polysaccharide characterized in that it contains at least a polysaccharide represented by the repeating unit of the following chemical formula (1) into the sheet-like cosmetic. It has been found that even if it is placed on the skin for a long time, after the cosmetic is taken, there is little stickiness, and it does not inhibit the penetration of the active ingredient into the skin, and the present invention has been completed.

  Examples of the active ingredient include a whitening ingredient, an anti-inflammatory ingredient, a moisturizing ingredient, and the like. In a sheet-form cosmetic blended with the alkali-genes-producing polysaccharide, these active ingredients contained in the sheet-form cosmetic are The present inventor has found that it has good skin permeability, and thus has completed a method for improving the skin quality in which the sheet-like cosmetic is applied to the face and body.

  The alkaline-genes-producing polysaccharide used in the present invention is a hydrophilic polymer compound, and is sold by Hakuto Co., Ltd. under the trade name “Alcacylan”. The sheet-like cosmetic of the present invention is prepared by impregnating or applying a cosmetic ingredient containing an alkaligenes-producing polysaccharide on a sheet-like base material. The content of the alkaligenes-producing polysaccharide is impregnated or applied to the makeup. It is 0.001 to 1 weight% with respect to the total amount of a component, Preferably it is 0.01 to 0.5 weight%. More preferably, it is 0.02 to 0.1% by weight. If the amount is less than 0.001% by weight, the effect of the present invention may not be sufficiently exerted. If the amount exceeds 1% by weight (hereinafter, “% by weight” is referred to as “%”), the cosmetic component thickens, and the sheet-like base It may be difficult to impregnate or apply the material.

Alkaligenes-producing polysaccharides are different from other water-soluble synthetic polymers and polysaccharides in the state of aqueous solutions. When a general water-soluble synthetic polymer or polysaccharide is dissolved in water, it spreads like a string in water. On the other hand, since the alkaligenes-producing polysaccharide does not spread in water and has a spherical shape like a yarn ball, the affinity site with water is small, and the alkaligenes-producing polysaccharide is not dissolved in water. In addition, even in contact with the skin, general hydrophilic polymers are adsorbed as lines and surfaces, but the alkaligenes-producing polysaccharide is adsorbed at points, so there is little contact area, and as a result, sticky Stickiness is reduced. Moreover, since the affinity part with water is small, it is hard to receive the influence of the electrolyte of a salt compound, and a gel viscosity does not fall.
Alkaligenes-producing polysaccharides are spherical, connect in a rosary shape, extend into fibers, and entangle with each other to construct a micro-sized network in water. This is a micro sponge that does not dissolve in water and has free water. When using sheet-like cosmetics on the skin, the alkaline-genes-producing polysaccharide network releases free water and moisturizes and provides the active ingredients to the skin. As described above, the alkali-genes-producing polysaccharide (trade name “Arcasilan”) is not dissolved in water unlike a general hydrophilic polymer, and thus the stickiness is reduced after the sheet-like cosmetic is peeled off.

(Test to evaluate the stickiness of sheet-like cosmetics)
The stickiness of the sheet-like cosmetic was evaluated by a sensory test with a total of 5 panelists of 1 male and 4 females. In addition, the moisturizing feeling was also evaluated.
After the face washes, evaluation was performed based on a sticky feeling and a moisturizing feeling after a sheet was attached to the face for 15 minutes. The evaluation points are as follows, and the results are shown in Table 2.
(Stickiness)
3 points: Strongly feels like sliding.
2 points: Feels like sliding.
1 point: I feel a little sticky.
0 points: I feel sticky.
(Moisturizing feeling)
3 points: I feel a moist feeling strongly.
2 points: I feel a moist feeling.
1 point: I feel a little moist.
0 points: Does not feel moist.
In Table 2, “total” is the total of the evaluation points of all panelists, and “average” is the evaluation point per panelist. In any case, the larger the value, the less stickiness and the stronger the moisturizing feeling.

  According to the results in Table 2, in Examples 1 and 2, the stickiness is an average of 2.0 points or more, there is no stickiness, and it feels like a slipping feeling, and also in the moisturizing feeling. The average score was 2.0 or more, and it was evaluated that a moist feeling was felt. On the other hand, in Comparative Example 1, the sticky feeling remained at an average of 1.4 points, and the moisturizing feeling was 1.0 points.

(Test to evaluate the penetration of active ingredients into the skin)
The penetration of the active ingredient in the sheet-form cosmetic was evaluated using Example 1 and Comparative Example 1 by measuring the degree of recovery of the skin that caused a weak sunburn. Evaluation was performed by the amount of melanin, the degree of erythema, and the moisture content of the skin.
The amount of melanin and the degree of erythema were measured by Mexometer MX18 Course + Khazaka (Germany). The measurement principle is that light of a specific wavelength is applied to the skin and the amount of light absorbed by the skin is expressed as a numerical value. The larger the numerical value, the greater the light absorption and the darker the color of melanin and erythema. Is shown. By changing the wavelength of light, absorption by melanin and absorption by erythema are distinguished and measured.
The skin capacitance was used as an index of the skin moisture content. For the measurement of capacitance, Corneometer CM 825, manufactured by Curage + Khazaka (Germany) was used. The measurement principle uses the fact that the capacitance increases when the skin contains a lot of water, and numerical values are displayed as relative values of 0 to 120 according to the measured capacitance. The higher the number, the more moisture in the skin.
That is, the smaller the numerical value of the amount of melanin and the degree of erythema, the better the skin condition, and the larger the numerical value of the amount of water, the better the skin condition.

(Test method)
From the day exposed to sunlight outdoors with UV illuminance of 1400-1800 (uW / cm ² ), Example 1 was applied to the right cheek for 30 minutes once a day before going to bed, and Comparative Example 1 was applied to the left cheek for 30 minutes. The amount of melanin, the degree of erythema, and the moisture content of the skin were measured and compared before the sun, in the evening the day after the bathing, and in the evening after 10 days. The measurement was performed at five locations, the average value was obtained, and the results are shown in Table 3.

  According to the results in Table 3, in both Example 1 and Comparative Example 1, the amount of melanin and the degree of erythema increased and the amount of water decreased on the day after the sunburn, but the tanning occurred due to the application of the sheet-like cosmetic for the subsequent 10 days. As for the degree of recovery of the skin that gave rise to the skin, the degree of recovery of Example 1 was clearly superior to the degree of recovery of Comparative Example 1 in any evaluation of the amount of melanin, the degree of erythema, and the amount of moisture of the skin.

  By applying the sheet-like cosmetic composition of the present invention, all of the amount of melanin that is an effect index of the whitening component, the degree of erythema that is the effect index of the anti-inflammatory component, and the amount of moisture of the skin that is the effect index of the moisturizing component The sheet-like cosmetic composition of the present invention showed that the penetration of these active ingredients into the cosmetic ingredient was not inhibited and the permeability was very high.

As a result of the above evaluation tests, in the sheet-like cosmetic of the present invention, even when the cosmetic is placed on the skin for a long time, after taking the cosmetic, there is little stickiness, and the active ingredient in the cosmetic ingredient The remarkable effect of the present invention that does not inhibit the penetration of the skin into the skin has been demonstrated.
