Description

Cosmetic or medical material

This disclosure relates to cosmetics or medical materials.

In the cosmetic field, the pharmaceutical field, and the like, an active ingredient is absorbed from a living body, for example, skin, that is, a cosmetic effect, a disease treatment or a preventive effect is generated by transdermal absorption. For example, ascorbic acid has the function of suppressing the production of wrinkle-related collagen and the production of tannins and sunburns and melanin, as well as reducing melanin, so that ascorbic acid penetrates into the lower layer of the skin epidermis where melanin is produced. If done, it will be effective in preventing and treating sunburn.

However, ascorbic acid is a water-soluble substance and hardly penetrates from the hydrophobic skin surface into the skin. For this reason, it has been proposed to use an accelerator that promotes absorption of ascorbic acid into the skin, such as vitamins B6 and B3 and nicotinamide. For example, Patent Documents 1 to 3 disclose a composition for external use containing a substance having a cosmetic effect such as ascorbic acid and an accelerator that promotes absorption of skin such as ascorbic acid.

Japanese Patent Laid-Open No. 6-107531 JP 2006-45140 A JP 2007-509899 A

(Composition of cosmetics or medical materials)
The cosmetic or medical material of the present disclosure includes a transdermal absorption enhancer, an active ingredient, and a biocompatible film. Hereinafter, each component will be described in detail. When an active ingredient of a cosmetic is provided, it may be called a cosmetic, and when an active ingredient of a pharmaceutical is provided, it may be called a medical material. Further, the cosmetics or medical materials of the present disclosure include quasi-drugs classified between cosmetics and pharmaceuticals.

(1) Transdermal absorption enhancer The transdermal absorption enhancer means an agent that increases the amount of penetration of desired components into the skin. The transdermal absorption enhancer of the present application is a cyclic compound represented by the formula (1). Hereinafter, the cyclic compound that is a transdermal absorption enhancer is referred to as a first cyclic compound. In addition, as will be described later, a compound which is an active ingredient in the cosmetic field, pharmaceutical field and the like targeted by the present application is also a cyclic compound (hereinafter referred to as a second cyclic compound). Therefore, interaction between the first cyclic compound and the second cyclic compound is likely to occur, and both the first cyclic compound and the second cyclic compound can easily penetrate into the skin. It is possible to enhance the percutaneous absorption promoting effect of the second cyclic compound.

Desirably, at least one of the first cyclic compound and the second cyclic compound is an aromatic compound, and more desirably, both the first cyclic compound and the second cyclic compound are aromatic compounds. is there. When at least one of the first cyclic compound and the second cyclic compound is an aromatic compound, an interaction derived from an aromatic ring can be used, and the first cyclic compound and the second cyclic compound can be used. The interaction between the cyclic compound and the second cyclic compound is more likely to occur, and both the first cyclic compound and the second cyclic compound are likely to penetrate into the skin.

In addition, it is desirable that at least one of the first cyclic compound and the second cyclic compound includes a hydroxyl group, a carboxyl group, or both. By including a hydroxyl group and a carboxyl group, it becomes possible to use a hydrogen bond or the like for the interaction between the first cyclic compound and the second cyclic compound, and the two cyclic compounds are more likely to interact with each other. It becomes easy to penetrate into the skin.

Specifically, the first cyclic compound is a cyclic compound represented by the following formula (1) or a salt thereof.

In the formula (1), X is CH, N, CH ₂ or NH, the adjacent atoms of 1 to 6 are a saturated bond or an unsaturated bond, and R ₁ is at least one of a carboxyl group and a hydroxyl group R ₂ is at least one selected from the group consisting of propenoic acid group, isopropyl group, methoxy group, aldehyde group, methyl group, hydroxymethyl group, and hydrogen, m is an integer of 1 or more, n Is an integer of 0 or more, and the sum of m and n is 10 or less.

In the formula (1), m is 2 or more, that is, when the R ₁ there are two or more, R ₁ is each independently a carboxyl group or a hydroxyl group.

Further, in the equation (1), n is 2 or more, that is, when R ₂ is present two or more, R ₂ are each independently propene group, an isopropyl group, a methoxy group, an aldehyde group, a methyl group , A hydroxymethyl group or hydrogen.

The salt of the first cyclic compound is a salt of an anion having a proton removed from the carboxyl group or hydroxyl group of the first cyclic compound and any monovalent or polyvalent cation, or X is NH. Contains the hydrochloride salt in some cases.

The first cyclic compound represented by the formula (1) or a salt thereof includes, for example, nicotinic acid, sodium nicotinate, vanillic acid, sodium vanillate, gallic acid, ferulic acid, sodium ferulate, pyridoxal, pyridoxal hydrochloride, Menthol, pyromellitic acid, mellitic acid, trimellitic acid, hydroxybenzoic acid, dihydroxybenzoic acid, hydroxyisophthalic acid, isovanillic acid, syringic acid, anisic acid, methoxysalicylic acid, trimethoxybenzoic acid, phloroglucinol, methoxycatechol, resorcinol, It is at least one selected from the group consisting of pyrogallol, methoxyhydroquinone, syringic acid, methyl pyrogallol, and vanillin.

Cosmetics or medical materials may contain only one kind of the aforementioned first cyclic compound as a transdermal absorption enhancer, or may contain two or more kinds.

The molecular weight of the first cyclic compound or a salt thereof is desirably 94 or more and 500 or less. When the molecular weight is 500 or less, the size of the molecule or ion of the first cyclic compound becomes small, and the first cyclic compound easily penetrates into the skin. The first cyclic compound or a salt thereof desirably has higher hydrophobicity than the second cyclic compound described later. As described above, the first cyclic compound is more hydrophobic than the second cyclic compound, which is the active ingredient, so that the complex due to the interaction between the first cyclic compound and the second cyclic compound. The body has a higher hydrophobicity than the second cyclic compound and the permeability to the skin is increased.

The hydrophobicity of the first cyclic compound can be evaluated by, for example, a partition coefficient. The partition coefficient is an actually measured value of the equilibrium solubility ratio when the compound is dissolved in two phases of water and n-octanol, and the partition coefficient P = log ₁₀ ((the concentration of the compound in n-octanol) / (in water). Compound concentration)). The higher the partition coefficient P, the higher the hydrophobicity (or fat solubility) of the compound. Further, when the compound is more soluble in water than n-octanol, the partition coefficient takes a negative value.

The partition coefficient of the first cyclic compound is desirably 0 or more. More desirably, it is 0 or more and 4.0 or less. If the partition coefficient is 0 or more, the first cyclic compound can penetrate into the skin, and when it forms a complex with the second cyclic compound, the second cyclic compound as an active ingredient is It can be absorbed into the skin more than when used alone. If the distribution coefficient is greater than 4.0, the hydrophobicity of the first cyclic compound may be too high, making it difficult to penetrate into the skin.

(2) Active ingredient As mentioned above, the active ingredient which this application makes object is the 2nd cyclic compound or its salt. As a result, there is little steric hindrance between the first cyclic compound and the second cyclic compound, and the interaction is likely to occur, and both the first cyclic compound and the second cyclic compound are in the skin. It is thought that it becomes easy to penetrate into.

As described above, it is desirable that the second cyclic compound is also an aromatic compound. The second cyclic compound preferably contains a hydroxyl group, a carboxyl group, or both. The salt of the second cyclic compound includes a salt of an anion in which a proton is eliminated from the carboxyl group or hydroxyl group of the second cyclic compound and any monovalent or polyvalent cation.

As a cosmetic effect by the second cyclic compound, for example, it may have whitening, anti-wrinkle, UV cut, moisturizing effect and the like. Beauty ingredients satisfying such conditions include, for example, vitamin A such as retinol, retinal, retinoic acid, vitamin B such as thiamine, riboflavin, pyridoxine, pyridoxamine, folic acid, vitamin D such as ergocalciferol, cholecalciferol, α -Vitamin E such as tocopherol, vitamins such as phylloquinone, menaquinone vitamin K, vitamin A derivatives such as tretinoin, retinol palmitate, glyceryl ascorbic acid, L-ascorbic acid-2-magnesium phosphate, ascorbic acid glucoside, etc. Vitamin C derivatives, vitamin E derivatives such as α-tocopherol acetate, α-tocopheryl quinone, tocopheryl phosphate, tranexamic acid, arbutin, hydroquinone, kojic acid, potassium 4-methoxysalicylate Lucinol, ellagic acid and gossypetin, myricetin, flavonols of rutin, proline, phenylalanine, there is tryptophan, tyrosine, an amino acid such as histidine. Moreover, as a medical effect by a 2nd cyclic compound, you may have effects, such as analgesia, vasodilation, angina treatment, asthma treatment, etc., for example. Medical components that satisfy such conditions include, for example, acetylsalicylic acid, thiaramide hydrochloride, acetaminophen, hydrocortisone, prednisolone, triamcinolone, dexamethasone, betamethasone, minoxidil, finasteride, cephalanthin, isosorbide mononitrate, isosorbide dinitrate, bisoprolol, estrone, Examples include estradiol and estriol.

When the cosmetic or medical material of the present disclosure is mainly used as a cosmetic or medical material having an effect such as whitening, the second cyclic compound is selected from the group consisting of ascorbic acid, sodium ascorbate, arbutin, and ellagic acid. It is preferable to include at least one selected.

The active ingredient used in the present disclosure may contain one of these second cyclic compounds, or may contain two or more of the same uses or two or more of different uses. Moreover, the salt of these 2nd cyclic compounds, hydrochloride, etc. may be sufficient.

The molecular weight of the second cyclic compound or a salt thereof is desirably 4000 or less. When the molecular weight is 4000 or less, the size of the molecule or ion of the second cyclic compound becomes small, and the second cyclic compound easily penetrates into the skin. Furthermore, the molecular weight of the second cyclic compound or a salt thereof is more desirably 500 or less. When the molecular weight is 500 or less, the size of the molecule or ion of the second cyclic compound becomes smaller, and the second cyclic compound is more likely to penetrate into the skin.

Further, as described above, it is desirable that the first cyclic compound has higher hydrophobicity than the second cyclic compound or a salt thereof. Thus, when the first cyclic compound which is a transdermal absorption enhancer is used, the hydrophobicity of the complex of the first cyclic compound and the second cyclic compound is reduced to the second cyclic compound. It increases compared to a simple substance, and the second cyclic compound is easily absorbed percutaneously.

In particular, when the distribution coefficient of the second cyclic compound is less than 0, the second cyclic compound alone is difficult to absorb percutaneously. When such a second cyclic compound having a partition coefficient of less than 0 is used, the percutaneous absorption promoting effect of the first cyclic compound works more effectively, and the absorption to the skin can be enhanced. For example, as the second cyclic compound having a partition coefficient of less than 0, riboflavin, pyridoxine, pyridoxamine, folic acid, glyceryl ascorbic acid, L-ascorbic acid-2-magnesium phosphate, ascorbic acid glucoside, 3-O-methyl-L- Examples include ascorbic acid, tocopheryl phosphate, arbutin, kojic acid, proline, phenylalanine, tryptophan, tyrosine, histidine, rutin, and isosorbide mononitrate.

Ascorbic acid is known to be effective for, for example, spots and wrinkles. The molecular weight of ascorbic acid is 200 or less, but the partition coefficient is said to be -1.85. For this reason, ascorbic acid generally has low skin permeability. When ascorbic acid is used as the second cyclic compound of the cosmetic or medical material of the present disclosure, as will be described in the following examples, when the first cyclic compound is used, absorption into the skin is used alone Increased compared to

(3) Biocompatible membrane The biocompatible membrane can hold at least one of the first cyclic compound or a salt thereof and the second cyclic compound or a salt thereof. Since the biocompatible membrane is brought into contact with or attached to the skin or the like, it is desirable to have biocompatibility. The biocompatibility means that redness, irritation, or the like hardly occurs in a living body such as skin due to its use, or that these hardly occur in many subjects.

As will be described later, the biocompatible membrane includes a first cyclic compound or a salt thereof in a solid state, a state dissolved in an appropriate liquid, or a state dispersed in a gel, and a second cyclic compound or a salt thereof. It is possible to retain at least one of the salt. Thereby, it is possible to stably maintain at least one of the first cyclic compound and the second cyclic compound in contact with a living body, for example, skin.

It is desirable that the biocompatible membrane can be self-supporting. Self-supporting means that the membrane can be maintained without any other support. For example, when a part of the biocompatible membrane is picked up by using fingers, tweezers, etc., the membrane breaks. It means that it is possible to lift the whole without a support.

Biocompatible membrane materials include collagen, hyaluronic acid, polyglutamic acid, chondroitin sulfate, dermatan sulfate, keratan sulfate, heparan sulfate, heparin, chitin, chitosan, dextran, dextrin, gluten, lignin, pectin, pullulan, xanthan gum, xylan, poly Materials that are safe for living bodies such as lactic acid, cellulose, and cellulose derivatives such as hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, methyl cellulose, and ethyl cellulose are preferable. A more preferred material is regenerated cellulose. Regenerated cellulose has the characteristic of not having the type I crystal characteristic of natural cellulose, so that it can easily retain moisture moderately and can have an excellent humidity control function. Accordingly, when the regenerated cellulose is attached to a living body, it does not easily cause stuffiness or rash while retaining appropriate moisture. Furthermore, it can be expected that the ability to carry the first and second cyclic compounds is enhanced by controlling the structure of the regenerated cellulose such as the pore and density.

The raw material cellulose used for producing the biocompatible membrane is not particularly limited. For example, natural cellulose derived from plant species, natural cellulose derived from living organisms, or regenerated cellulose such as cellophane or processed cellulose such as cellulose nanofibers can be applied. Further, it is beneficial that the impurity concentration of the raw material cellulose is 10 wt% or less.

It is desirable that the biocompatible membrane has a thickness of 3 μm or less. If the thickness of the biocompatible membrane is 3 μm or less, there is little discomfort when placed on the skin, and wearability can be improved. In particular, the thickness of the biocompatible membrane is more preferably 20 nm or more and 1300 nm or less. When the thickness is 1300 nm or less, the biocompatible film can be attached to the skin without using an adhesive or a pressure-sensitive adhesive, or an adhesive layer or a pressure-sensitive adhesive layer. As a result, stuffiness and the like can be reduced without burdening the living body, and cosmetics or medical materials can be used.

The biocompatible membrane has a size corresponding to the use of the cosmetic or medical material and the site of the skin to be used. For example, the biocompatible membrane can be applied to the skin such as the face and arms. Biocompatible membranes according to embodiments of the present disclosure typically have an area of 7 mm ² or greater. When the area of the biocompatible membrane is 7 mm ² or more, it is possible to obtain a cosmetic effect by covering a local region of the skin such as a stain. Moreover, if a biocompatible membrane having a larger area is used, it is possible to cover the skin over a wide range. The cosmetic or medical material of the present disclosure can be applied to a living body other than the skin. For example, in order to enhance the healing effect of the organ, it can be attached to the surface of the organ.

The ratio of the mass of the first cyclic compound or salt thereof to the total mass of the biocompatible membrane carrying the first cyclic compound or salt thereof is preferably 0.1 to 50 mass ratio. If it is 0.1 mass ratio or more, the effect of promoting percutaneous absorption of the first cyclic compound can be obtained, and the second cyclic compound can effectively penetrate into the skin. When the first cyclic compound is supported on the biocompatible membrane at a mass ratio of 50 or less, the biocompatible membrane maintains high strength and is stably attached to the skin.

The ratio of the mass of the second cyclic compound or salt thereof to the total mass of the biocompatible membrane carrying the second cyclic compound or salt thereof is preferably 0.5 or more and 50 mass ratio or less. If it is 0.5 mass ratio or more, the 2nd cyclic compound can be penetrated into skin effectively. When the second cyclic compound is supported on the biocompatible membrane at a mass ratio of 50 or less, the biocompatible membrane maintains high strength and is stably attached to the skin.

(4) Mounting liquid When at least one of the first cyclic compound and the second cyclic compound is a solid, the first cyclic compound and the second cyclic compound are uniformly supported on the biocompatible membrane. The cosmetic or medical material may further include a mounting liquid in order to adhere to the skin on which the biocompatible membrane is disposed. A liquid that is safe for a living body can be used as the mounting liquid. For example, the mounting liquid includes at least one selected from an aqueous solution such as pure water, physiological saline, lotion, and beauty liquid, and a lotion, an emulsion, a cosmetic liquid, and a cream containing an organic solvent. Desirably, the mounting fluid includes water and a polyhydric alcohol. Examples of the polyhydric alcohol include glycerol and propanediol, and the mounting solution may contain both glycerol and propanediol. Since polyhydric alcohol is slightly more hydrophobic than water, the mounting liquid containing water and polyhydric alcohol can dissolve both the first cyclic compound and the second cyclic compound. Thereby, the first cyclic compound and the second cyclic compound are uniformly disposed in the biocompatible membrane, the first cyclic compound and the second cyclic compound interact, and the complex is removed from the skin. It is possible to permeate into.

The concentration of the mounting liquid desirably includes, for example, 5% by mass to 10% by mass of glycerol, 5% by mass to 15% by mass of propanediol, and the remaining water. Since the mounting liquid of this formulation has little irritation to the skin or the like, it is possible to easily mount the biocompatible membrane containing the mounting liquid for a long time.

(5) Other components Components of cosmetics or medical materials other than the first cyclic compound and the second cyclic compound may be included. For example, as ingredients of cosmetics, hyaluronic acid, ceramide, collagen, amino acid, elastin, various extracts, citric acid, lecithin, carbomer, xanthan gum, dextran, palmitic acid, lauric acid, petrolatum, titanium oxide, iron oxide, phenoxyethanol, fullerene , Astaxanthin, coenzyme, human oligopeptide, glycerin, diglycerin, sodium lactate, sorbitol, pyrrolidone carboxylic acid, fatty acid polyglyceryl, polyglycerin, jojoba oil, trimethylglycine, mannitol, trehalose, glycosyl trehalose, pullulan, erythritol, elastin, dipropylene Glycol, butylene glycol, ethyl ethylhexanoate, sodium acrylate, disodium edetate, sucrose fatty acid Ester, squalane, polyethylene glycol, polyoxyethylene hydrogenated castor oil, glyceryl stearate, ethanol, polyvinyl alcohol, hydroxyethyl cellulose, ectoine, and the like. In addition, as components of medical materials, isosorbide nitrate, indomethacin, diflucortron valerate, acyclovir, ketoconazole, ketoprofen, diclofenac sodium, dexamethasone propionate, felbinac, clobetasol propionate, loxoprofen, methyl salicylate, tacrolimus, etc. Can be mentioned.

(Aspects of cosmetics or medical materials)
The cosmetic or medical material can be configured in various ways.

(1) Supporting the first and second cyclic compounds on the biocompatible membrane The first cyclic compound and the second cyclic compound may be supported on the biocompatible membrane in advance. When the first cyclic compound and the second cyclic compound are solid at room temperature, the first cyclic compound and the second cyclic compound can be supported on the biocompatible membrane in a solid state. For example, when the second cyclic compound is ascorbic acid, the reduced form is considered to have cosmetic effects such as suppression of melanin production, hyaluronic acid synthesis, and UV cut. However, ascorbic acid easily changes from a reduced form to an oxidized form in an aqueous solution. Therefore, when the biocompatible membrane is loaded with reduced ascorbic acid as the second cyclic compound in a solid state, it is difficult to be oxidized. Similarly, the first cyclic compound is supported in a solid state. This makes it possible to stably hold the first cyclic compound and the second cyclic compound for a long period of time.

The first and second cyclic compounds may be carried in the biocompatible membrane, or may be carried on the surface of the biocompatible membrane. In order to prevent the first and second cyclic compounds from being removed by friction or the like, it is desirable that the first and second cyclic compounds are supported in the biocompatible membrane.

(2) One of the first and second cyclic compounds carried on the biocompatible membrane One of the first cyclic compound and the second cyclic compound may be carried on the biocompatible membrane in advance. The other of the first cyclic compound and the second cyclic compound can be obtained by, for example, dissolving the other in the mounting liquid and including the mounting liquid in the biocompatible membrane when using cosmetics or medical materials. Cyclic compounds may be placed on the biocompatible membrane. In addition, for example, when there is an adverse effect such as decomposition due to strong interaction between the first cyclic compound and the second cyclic compound, it is supported on the biocompatible membrane for the purpose of separating and holding one. It does not have to be.

(3) Arranging the first and second cyclic compounds later The first and second cyclic compounds may be stored separately from the biocompatible membrane. That is, both the first cyclic compound and the second cyclic compound may be arranged on the biocompatible membrane at the time of use without being supported on the biocompatible membrane. In this case, for example, at the time of use, the first cyclic compound and the second cyclic compound may be dissolved in the mounting solution, and the mounting solution in which the two cyclic compounds are dissolved may be disposed on the biocompatible membrane by dropping or the like. Good. Alternatively, a first mounting liquid and a second mounting liquid in which the first cyclic compound and the second cyclic compound are respectively dissolved are prepared, and the first mounting liquid and the second mounting liquid are used as a living body at the time of use. You may arrange | position by making it drop on a suitable film | membrane. In these forms, the first cyclic compound and the second cyclic compound can be arranged on the skin surface more than the case where they are supported on the biocompatible membrane, and the amount of penetration into the skin can be improved. May be possible.

(How to use cosmetics or medical materials)
The cosmetic or medical material of the present disclosure is used in such a manner that the first cyclic compound or a salt thereof and the second cyclic compound or a salt thereof are held on the biocompatible film and the biocompatible film is brought into contact with the skin. To do. When the biocompatible membrane is brought into contact with the skin and used, the first cyclic compound or a salt thereof and the second cyclic compound or a salt thereof may be held on the biocompatible membrane, and the makeup of the present disclosure The material or the medical material may be any one of the above embodiments (1) to (3). The method of using the cosmetic or medical material according to the present disclosure is classified into the following three types according to the timing at which the mounting liquid is arranged. When any one of the above-described three usage modes is used, the mounting liquid can be arranged at the following three types of timing.
(1) When dripping onto the skin First, the mounting solution is dropped onto the surface of the skin, and a biocompatible membrane is applied to the skin so as to cover the dropped mounting solution.
(2) When dropping onto the biocompatible membrane First, the mounting solution is included in the biocompatible membrane, and the biocompatible membrane containing the mounting solution is applied to the skin.
(3) When dropping onto the biocompatible membrane placed on the skin First, the biocompatible membrane is placed on the skin, and the mounting solution is dropped over the biocompatible membrane.

The biocompatible membrane can stably maintain the state in which the skin and the mounting liquid are in contact with each other at any timing. For this reason, the first cyclic compound and the second cyclic compound in the wearing solution can be stably percutaneously absorbed into the skin for a long period of time.

(effect)
According to the cosmetic or medical material of the present disclosure, the first cyclic compound represented by formula (1) or a salt thereof and the second cyclic compound or salt thereof as an active ingredient have a ring structure. Therefore, an interaction is likely to occur between the first cyclic compound and the second cyclic compound, and both the first cyclic compound and the second cyclic compound easily penetrate into the skin. Moreover, the cyclic compound represented by the formula (1) is a substance that has a relatively large partition coefficient and is easily absorbed through the skin. Therefore, even if the second cyclic compound is water-soluble, that is, the second cyclic compound has a small partition coefficient and is hardly percutaneously absorbed, it forms a complex with the first cyclic compound. This facilitates percutaneous absorption, and allows the second cyclic compound to effectively penetrate into the skin.

In addition, the cosmetic or medical material of the present disclosure includes a biocompatible film, and the biocompatible film includes, for example, a first cyclic compound or a salt thereof dissolved in a liquid, and a second cyclic compound or a salt thereof. And can be held stably. Since the biocompatible film is hypoallergenic, it is possible to realize a cosmetic or a medical material that can be applied to the skin for a period of time depending on the application.

(Manufacturing method of cosmetics or medical materials)
(1) 1st cyclic compound and 2nd cyclic compound The 1st cyclic compound and the 2nd cyclic compound are commercial items provided with use, purity as required, safety for specimen, etc. Can be used.

(2) Wearing liquid The wearing liquid is pure water, physiological saline, commercially available lotion, aqueous solution such as cosmetic liquid, lotion containing organic solvent, milky lotion, cosmetic liquid, cream, etc. or the first cyclic compound. Or a solution containing beauty and medical ingredients and the above-mentioned polyhydric alcohol in the above-mentioned ratio.

(3) Biocompatible membrane A biocompatible membrane composed mainly of regenerated cellulose can be produced, for example, by the following method.

First, a cellulose solution is prepared by dissolving cellulose in a solvent. The cellulose used preferably has a weight average molecular weight of 30,000 or more. When cellulose having a weight average molecular weight of 150,000 or more is used, a biocompatible membrane having a thickness of 1300 nm (1.3 μm) or less can be obtained stably.

As the cellulose, as long as it has a predetermined weight average molecular weight, cellulose derived from plants such as pulp or cotton, or cellulose produced by organisms such as bacteria can be used. It is useful that the impurity concentration of cellulose as a raw material is 10 wt% or less.

As the solvent, a solvent containing an ionic liquid may be used. By using a solvent containing at least an ionic liquid, cellulose can be dissolved in a relatively short time. An ionic liquid is a salt composed of an anion and a cation, and can exhibit a liquid state at a temperature of 150 ° C. or lower. As the ionic liquid for dissolving cellulose, an ionic liquid containing an amino acid or an alkyl phosphate ester can be used. By using such an ionic liquid as a solvent, cellulose can be dissolved while suppressing a decrease in molecular weight. In particular, since an amino acid is a component present in a living body, it can be said that an ionic liquid containing an amino acid enables the production of a regenerative biocompatible membrane that is safer for the living body.

As the ionic liquid for dissolving cellulose, for example, an ionic liquid represented by the following general formula (s1) can be used. The ionic liquid represented by the general formula (s1) is an example in which the anion is an amino acid. As can be seen from the general formula (s1), in this example, the anion includes a terminal carboxyl group and a terminal amino group. The cation of the ionic liquid represented by the general formula (s1) may be a quaternary ammonium cation.

In general formula (s1), R ₁ to R ₆ independently represent a hydrogen atom or a substituent. The substituent may be an alkyl group, a hydroxyalkyl group or a phenyl group, and may contain a branch in the carbon chain. The substituent may include an amino group, a hydroxyl group, a carboxyl group, and the like. n is an integer of 1 or more and 5 or less.

Or the ionic liquid represented by the following general formula (s2) can also be used as an ionic liquid which melt | dissolves a cellulose. In the following general formula (s2), R ₁ , R ₂ , R ₃ and R ₄ independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms (C ₁ -C ₄ ).

The obtained cellulose solution is applied to an appropriate substrate to obtain a polymer gel sheet (also referred to as a liquid film) supported on the substrate. Thereafter, the polymer gel sheet on the substrate is immersed in a liquid that does not dissolve cellulose (hereinafter sometimes referred to as “rinse solution”). This step may be said to be a step of washing the polymer gel sheet in which the solvent containing the ionic liquid is removed from the polymer gel sheet.

As the liquid (rinsing liquid) in which the polymer gel sheet is immersed, a solvent that can be dissolved in at least an ionic liquid can be used. Examples of such liquids are water, methanol, ethanol, propanol, butanol, octanol, toluene, xylene, acetone, acetonitrile, dimethylacetamide, dimethylformamide, dimethyl sulfoxide.

Thereafter, the solvent and the like are removed from the polymer gel sheet. In other words, the polymer gel sheet is dried. As a drying method, various drying methods such as natural drying, vacuum drying, heat drying, freeze drying, and supercritical drying can be applied. Vacuum heating may be performed. The conditions for drying are not particularly limited, and a time and temperature sufficient to remove a part or all of the solvent and the rinsing liquid used for dissolving the cellulose solution may be applied. A biocompatible membrane can be obtained by removing the solvent from the polymer gel sheet.

When at least one of the first cyclic compound and the second cyclic compound is supported on the biocompatible membrane, for example, before or / and after the removal of the solvent and the rinse liquid from the polymer gel sheet, The obtained biocompatible membrane is immersed in a solution in which at least one of the first cyclic compound and the second cyclic compound is dissolved, and the biocompatible membrane is taken out of the solution and dried. Thereby, a biocompatible membrane carrying at least one of the first cyclic compound and the second cyclic compound is obtained.

Solvents for dissolving the first cyclic compound and the second cyclic compound include water, ethanol, propanol, butanol, acetone, glycerol, propanediol, 1,3-butanediol, 1,4-butanediol, diester Examples include glycerin, polyethylene glycol, and dimethicone. A plurality of these solutions may be used. Further, the sheet may be impregnated and supported by a solution containing components for beauty and medical use, or the components for beauty and medical use may be supported by spraying or vapor deposition.

The active ingredient other than the first cyclic compound and the second cyclic compound can be similarly supported on the biocompatible membrane.

(Example)

As comparative examples, nicotinamide and leucine acid used in place of the first cyclic compound are shown in Table 2. In the following examples, the second cyclic compound may be referred to as a cosmetic agent.

(1) Example 1

In Example 1, ascorbic acid or sodium ascorbate as the second cyclic compound and nicotinic acid or sodium nicotinate or gallic acid or sodium ferulate or pyridoxal hydrochloride or menthol as the first cyclic compound in the membrane A supported biocompatible membrane was used.

<Example 1A>
(Production of biocompatible membrane)
Cellulose derived from bleached pulp made of wood and having a purity of 90% or more was dissolved in an ionic liquid to prepare a cellulose solution. As the ionic liquid, an ionic liquid in which R ₁ is a methyl group and R ₂ to R ₄ are ethyl groups in the formula (s2) was used. A polymer gel sheet was formed by applying a cellulose solution on the substrate. At this time, the coating thickness was adjusted so that the thickness of the biocompatible membrane was 900 nm. Cleaning of the substrate and polymer gel sheet was performed.

Further, the polymer gel sheet washed in a solution in which sodium ascorbate and sodium nicotinate are dissolved in water is immersed and dried, so that the mass ratio to the membrane is 2.7% sodium ascorbate and sodium nicotinate 0 A biocompatible membrane carrying the first and second cyclic compounds of Example 1A carrying 2% was obtained. The film had a shape of approximately 5 cm square and a transparent appearance.

(Method for quantifying the second cyclic compound and the first cyclic compound in the film)
The mass ratio of sodium ascorbate and sodium nicotinate in the membrane to the membrane was obtained by the following method. In advance, sodium nicotinate was dissolved in ultrapure water, and a calibration curve was drawn for the concentration and absorbance at ₂₆₆ and ₂₂₀ nm measured with an absorptiometer UV-1600 (Shimadzu Corporation) to obtain slopes a ₂₆₆ and a ₂₂₀ , respectively. It was. Similarly, sodium ascorbate was dissolved in ultrapure water, a calibration curve was drawn for the concentration and absorbance at 266 nm, and slope b ₂₆₆ was obtained. The membrane was immersed in ultrapure water, the nicotinic acid concentration C _N in the solution extracted from 220nm absorbance I ₂₂₀ of a solution obtained by extracting the components of 1 hour film ultrasonically was determined using the calibration curve. Further, to obtain the extracted sodium ascorbate in the film by dividing the amount of solution L and multiplied film mass W mass ratio D _N. That is, the following formula is obtained.

On the other hand, for sodium ascorbate, a part of the spectrum of sodium ascorbate and sodium nicotinate is covered, so the concentration of sodium ascorbate cannot be calculated as it is. Therefore, first, the absorbance I ₂₆₆ of the extracted liquid was obtained. Then, sodium resulting nicotinic acid concentration C _N was calculated absorbance I _N266 of 266nm with sodium nicotinate. Using these values and b _266, Formula (III), to give ascorbic acid concentration by using (IV) C _A, and the mass ratio D _N of sodium ascorbate in the film.

(Verification of the cosmetic effect of the biocompatible membrane retaining the second cyclic compound with cultured skin)
As a three-dimensional cultured epidermis model containing melanocytes, MEL-300A (Kurashikibo Co., Ltd., hereinafter referred to as MEL) was used. During the culture test, maintenance and culture were carried out in a CO ₂ incubator (37 degrees, 5% CO ₂ ) using EPI-100LLMM long-term maintenance medium (Kurashikibo Co., Ltd., hereinafter referred to as EPI). After transferring the MEL to the plate, preculture was performed with 2 ml of EPI. Next, the MEL was transferred to a plate supplemented with 5 ml of EPI. The membrane of Example 1A was placed on the horny side of MEL, and the membrane surface was moistened with phosphate buffered saline (PBS). The EPI was changed one day after the membrane was installed and once every two days thereafter, and the biocompatible membrane and PBS were changed once every four days.

Except for using the EPI cultured skin permeation concentration P _A of sodium ascorbate 1 day after the film installation instead of ultra pure water, (quantification method of the second cyclic compound and the first cyclic compounds in the film) Using the formulas (I) to (III) of From the solution amount V _EPI of cultured skin permeation concentration of the resulting sodium ascorbate P _A and EPI with Formula (V), at determined cultured skin permeation amount M _A of sodium ascorbate after 1 day.

After continuous culture for 2 weeks, the cell viability of MEL was determined by the Alamar Blue method. A solution obtained by adding 0.20 g Alamar Blue (Cosmo Bio) to 1.8 g EPI was dropped onto the plate, and MEL was installed. After culturing for 2 hours, the fluorescence intensity (excitation wavelength: 544 nm, measurement wavelength: 590 nm) of the culture supernatant was measured with a spectrofluorometer FP-8500 (JASCO). The cell viability was calculated as a ratio to the fluorescence intensity when a membrane of Comparative Example 1A described later was added.

After washing the MEL with PBS, the cultured skin part was cut out from the MEL and moved to a glass bottle. Then, the solution was washed with an equal mass ratio of ethanol and diethyl ether and then with diethyl ether for more than half a day. The washed cultured skin site was immersed in a 1M aqueous sodium hydroxide solution to dissolve melanin in the cultured skin. The melanin content in the cultured skin was determined by measuring absorbance at 405 nm with an absorptiometer UV-1600 (Shimadzu Corporation) and calculating in advance from a calibration curve based on the dissolved concentration and absorbance of synthetic melanin (Sigma Aldrich Japan Co., Ltd.).
