Description

[Technical Field]

[0001] The present invention relates to a physical property stabilizer that can stabilize the physical properties of aqueous cosmetics over time without causing any change in the feel when used. [Background technology]

[0002] Aqueous cosmetics, which have an aqueous phase as the continuous phase, are widely used as cosmetics because they blend well with the skin and have an excellent feel when used. However, because the continuous phase is aqueous, they can easily become unstable. In particular, low-viscosity cosmetics such as emulsions and lotions are prone to problems such as emulsion breakdown over time, separation of the oil and water phases, and floating or sedimentation of dispersants and emulsions.

[0003] Therefore, methods of stabilizing the aqueous phase by adding a water-soluble polymer to the aqueous phase to thicken it have been studied. Among these, studies using xanthan gum are listed in Patent Documents 1 to 3.

[0004] Patent Document 1 discloses an emulsion-type topical skin preparation characterized by containing 0.5 to 2.0% by weight of xanthan gum as component A, and one or more selected from polyhydric alcohols or polyhydric alcohol-containing plant extracts extracted with polyhydric alcohols as component B, with the content of component B being three times or more by weight relative to component A. Patent Document 2 discloses a cosmetic preparation characterized by containing xanthan gum that is represented by a specific structural formula and has an apparent weight-average molecular weight of 16 million or more. Patent Document 3 discloses an oil-in-water emulsion cosmetic that contains 0.7 to 1.5 wt % xanthan gum as component A, one or more oily components that are liquid at room temperature as component B, one or more oily components that are semi-solid at room temperature as component C, and one or more oily components that are solid at room temperature as component D, and is characterized in that the total content of oily components B to D relative to component A is 7 times or more by weight. Another example of a study on the use of carrageenan is (Patent Document 4), which discloses a cosmetic additive characterized by having as its active ingredient fine carrageenan powder with a maximum particle size of 40 μm or less and an average particle size of 15 μm or less.

[0005] However, although the methods described in all of the documents are effective to a certain extent in stabilizing the emulsion, the texture when used is different, and there is a problem that the use of xanthan gum in particular causes stickiness. On the other hand, synthetic polymers such as carboxyvinyl polymers are also used, but they can change the feel of the product when used, and in recent years, there has been a growing demand for naturally derived ingredients, so their uses have sometimes been limited. Furthermore, if a cosmetic containing the above-mentioned thickener is stored at high temperatures in a place where temperature control is insufficient, the thickener's effectiveness will be lost. Thus, there is a strong demand for naturally derived ingredients that can stabilize emulsion without changing the feel or texture of the product, but currently there are no suitable options.

[0007] Therefore, an object of the present invention is to provide a naturally derived physical property stabilizer that can stabilize the physical properties of aqueous cosmetics over time without causing any change in the feel when used. [Means for solving the problem]

[0008] The present inventors conducted various studies to solve the above problems and found that the inclusion of a small amount of β-1,3-1,6-glucan can solve the above problems, and in particular stabilize the physical properties even under high temperature conditions such as above 40° C. This is a noteworthy point considering that many thickeners used in cosmetics rapidly lose their effectiveness under high temperature conditions such as above 40° C. That is, the present invention is a property stabilizer for aqueous cosmetics, which contains β-1,3-1,6-glucan as an active ingredient. [Effects of the Invention]

[0009] According to the present invention, the physical properties of an aqueous cosmetic preparation can be stabilized over time without causing any change in the feel during use. DETAILED DESCRIPTION OF THE INVENTION

[0010] The aqueous cosmetic property stabilizer of the present invention contains β-1,3-1,6-glucan as an active ingredient. β-1,3-1,6-glucan refers to β-glucose in which glucose units are linked via β-1,3-glycosidic and β-1,6-glycosidic bonds, and known types include (1) those whose main chain is β-1,3-glycosidic and has branched β-1,6-glycosidic bonds, and (2) those whose main chain is composed of β-1,3-glycosidic and β-1,6-glycosidic bonds. Note that, as the β-1,3-1,6-glucan used in the present invention, those having bonds such as β-1,4-glycosidic bonds in part can also be used, but the content of glucosidic bonds other than β-1,3-glycosidic and β-1,6-glycosidic bonds must be 10 mol % or less of the total of β-1,3-glycosidic and β-1,6-glycosidic bonds.

[0011] In the aqueous cosmetic property stabilizer of the present invention, any β-1,3-1,6-glucan can be used as the β-1,3-1,6-glucan. However, due to its good solubility, the β-1,3-1,6-glucan represented by the following general formula (1) is preferred:

[0012] [ka]

[0013] In the general formula (1), a represents a number of at least 20, and b represents a number of at least 1. The sum of a and b is a number that results in the mass-average molecular weight of the β-1,3-1,6-glucan represented by general formula (1) being 3,000 to 5,000,000. If the mass-average molecular weight of the β-1,3-1,6-glucan represented by general formula (1) is less than 3,000 or more than 5,000,000, the effect of stabilizing the physical properties without changing the feel of use of the cosmetic, particularly emulsion stability, may be insufficient. The mass-average molecular weight of the β-1,3-1,6-glucan represented by general formula (1) is preferably 5,000 to 3,000,000, more preferably 7,000 to 1,000,000, and most preferably 10,000 to 500,000. In the present invention, the mass average molecular weight of β-1,3-1,6-glucan refers to the mass average molecular weight converted to pullulan when analyzed by gel permeation chromatography (GPC) using water as a solvent. Note that "mass average molecular weight" is sometimes referred to as "weight average molecular weight."

[0014] Although there are no particular limitations on the method for measuring the mass-average molecular weight, one example is to use several types of pullulan with known molecular weights (at any concentration) to create a calibration curve (retention time on the x-axis, molecular weight on the y-axis) using a differential refractometer. Next, a sample (at any concentration) is measured, and the relative molecular weight (molecular weight in terms of pullulan) is generally calculated from the retention time using the calibration curve. However, because pullulan and β-1,3-1,6-glucan have different molecular sizes even when they have the same molecular weight (same number of glucose units) due to differences in their structures, gel shaking chromatography, which uses molecular sieving, only provides relative values, and correction allows for the calculation of intrinsic molecular weights that approximate absolute values. Correction can be performed by measuring the concentration of the sample and measuring three points: differential pressure viscosity, differential refraction, and light scattering. Specifically, the instrument constant k is first determined using a pullulan standard solution with known concentration, viscosity, and refractive index.

[0015] Next, the concentration of β-1,3-1,6-glucan in the bulk material was measured using the phenol-sulfuric acid method, and an aqueous solution of known concentration was prepared as the sample. The molecular weight was then calculated from the values ​​measured using a differential pressure viscosity detector, differential refractive index detector, and light scattering detector.

[0016] In the above general formula (1), the ratio of b to a is preferably 0.2 to 1, more preferably 0.5 to 0.95, and most preferably 0.6 to 0.9. The unit having a repeating number of a and the unit having a repeating number of b may be bonded randomly or in blocks.

[0017] The β-1,3-1,6-glucan represented by general formula (1) can be obtained by known methods, for example, by extraction from the cell walls or products of yeast, lactic acid bacteria, Bacillus subtilis var. natto, acetic acid bacteria, koji mold, algae such as chlorella and spirulina, and filamentous fungi. Among these, β-1,3-1,6-glucan, which has a high moisturizing effect on skin, can be extracted from black yeast (Aureobasidium pullulans). There are no particular limitations on the method for extracting β-1,3-1,6-glucan, and any known method may be used.

[0018] Furthermore, when concentrating the extracted β-1,3-1,6-glucan, any method can be used to remove water or powder the β-1,3-1,6-glucan, including, for example, spray drying, freeze drying, vacuum drying, heat drying, and precipitation with a solvent, which may be combined as appropriate.

[0019] The aqueous cosmetic physical property stabilizer of the present invention preferably contains the above-mentioned β-1,3-1,6-glucan in an amount of 0.1% by mass or more, preferably 0.5% by mass or more, and more preferably 0.7% by mass or more, based on the total amount of the stabilizer, as solids. If the amount is less than 0.1% by mass, the amount of aqueous cosmetic physical property stabilizer required to achieve effective effects may be too large.

[0020] In the aqueous cosmetic property stabilizer of the present invention, when the β-1,3-1,6-glucan is in the form of an aqueous solution, if the concentration of the β-1,3-1,6-glucan is 2% by mass or more, the β-1,3-1,6-glucan will not be completely dissolved and will tend to precipitate. In this case, by adding 50 to 90% by mass of a polyhydric alcohol having 2 to 6 carbon atoms, the stabilizer can be easily used as a property stabilizer.

[0021] Examples of the polyhydric alcohol having 2 to 6 carbon atoms include ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, propylene glycol, dipropylene glycol, 1,3-propanediol, 1,2-butanediol, 1,3-butanediol, 1,4-butanediol, 2,3-butanediol, 2-methyl-1,2-propanediol, 2-methyl-1,3-propanediol, 1,2-pentanediol, 1,3-pentanediol, 1,4-pentanediol, 1,5-pentanediol, 2,3-pentanediol, 2,4-pentanediol, 2-methyl-1,2-butanediol, 2-methyl-2,3-butanediol, 2-methyl-1, dihydric alcohols such as 4-butanediol, 3-methyl-1,2-butanediol, 3-methyl-1,3-butanediol, 2-ethyl-1,3-propanediol, 2,2-dimethyl-1,3-propanediol, 1,5-hexanediol, 1,6-hexanediol, 2,5-hexanediol, 3,3-hexanediol, 2-methyl-1,3-pentanediol, 2-methyl-1,5-pentanediol, 2-methyl-2,4-pentanediol, 3-methyl-1,5-pentanediol, 3-methyl-2,3-pentanediol, 3-methyl-2,4-pentanediol, 2-ethyl-2-methyl-1,3-propanediol, and 2,2-dimethyl-2,4-butanediol, or condensates thereof; Alicyclic dihydric alcohols such as 1,2-cyclopentanediol, 1,3-cyclopentanediol, 1,2-cyclohexanediol, 1,3-cyclohexanediol, and 1,4-cyclohexanediol;

[0022] trihydric alcohols such as glycerin, 1,2,3-butanetriol, 1,2,4-butanetriol, 2-methyl-1,2,3-propanetriol, 1,2,3-pentanetriol, 1,2,4-pentanetriol, 1,3,5-pentanetriol, 2,3,4-pentanetriol, 2-methyl-2,3,4-butanetriol, 2,3,4-hexanetriol, and 2-ethyl-1,2,3-butanetriol; tetrahydric alcohols such as erythritol, 1,2,3,4-pentatetrol, 2,3,4,5-hexatetrol, 1,2,4,5-pentanetetrol, 1,3,4,5-hexanetetrol, diglycerin, and sorbitan; Pentahydric alcohols such as adonitol, arabitol, xylitol, and triglycerin; hexahydric alcohols such as sorbitol, mannitol, iditol, inositol, dulcitol, talose, and allose; Examples thereof include glycerin monoethers such as 1-methyl glyceryl ether, 2-methyl glyceryl ether, 1-ethyl glyceryl ether, 2-ethyl glyceryl ether, 1-propyl glyceryl ether, 2-propyl glyceryl ether, 1-isopropyl glyceryl ether, and 2-isopropyl glyceryl ether.

[0023] Among these polyhydric alcohols, propylene glycol, dipropylene glycol, 1,3-butanediol, and glycerin are preferred, with 1,3-butanediol being more preferred, as they provide excellent dispersion stability for β-1,3-1,6-glucan.

[0024] When the polyhydric alcohol content is 50 to 90% by mass as described above, the water content in the physical property stabilizer of the present invention is preferably 5 to 27% by mass. If the water content is less than 5% by mass, the dispersion stability of β-1,3-1,6-glucan may decrease, while if it is more than 27% by mass, the β-1,3-1,6-glucan content may become relatively low, and even if fluidity is observed immediately after blending, it may become gel-like over time and the fluidity may decrease.

[0025] The physical property stabilizer of the present invention has a significant effect of stabilizing emulsion even in low-viscosity aqueous liquids, and therefore can be particularly suitably used as an "emulsion stabilizer." Furthermore, the physical property stabilizer of the present invention is particularly suitable for use as a "dispersion stabilizer" because it has a significant effect of suppressing sedimentation and stabilizing dispersion even in low-viscosity aqueous liquids containing water-insoluble microparticle components such as titanium oxide and zinc oxide.

[0026] The aqueous cosmetic property stabilizer of the present invention can be used by appropriately combining one or more of various ingredients that can be used in ordinary cosmetics depending on the intended use, such as various surfactants, various enzymes, drugs, preservatives, isotonicity agents, buffers, stabilizers, chelating agents, solubilizing agents, pH adjusters, fragrances, etc., in amounts that are usually used.

[0027] Next, the aqueous cosmetic preparation of the present invention will be described. The aqueous cosmetic preparation of the present invention is a cosmetic preparation in which the continuous phase is an aqueous phase, and includes those having an oil-in-water or water-in-oil-in-water emulsion form, aqueous solutions that are substantially free of oil, or those in which solids are dispersed.

[0028] The proportion of the aqueous phase is preferably 50 to 100% by mass, more preferably 60 to 100% by mass, and most preferably 80 to 100% by mass, based on the weight of the aqueous cosmetic preparation. If the aqueous phase is less than 50% by mass, the physical property stabilizer of the present invention may not exhibit its full effect.

[0029] The aqueous phase contains not only water but also components derived from the physical property stabilizer of the present invention and water-soluble components among the optional components described below, and the proportion of water in the aqueous phase is preferably 20% by mass or more, more preferably 50% by mass or more, and most preferably 80% by mass or more. If the proportion of water in the aqueous phase is less than 20% by mass, the effects of the physical property stabilizer of the present invention may not be fully exerted. The above moisture content includes not only general blend water, but also moisture derived from the above-mentioned physical property stabilizers and moisture contained in optional components described below.

[0030] Furthermore, the aqueous cosmetic preparation of the present invention preferably has a viscosity at 25°C, as measured with a cone-and-plate rotational viscometer, of 500 mPa·s or less, more preferably 300 mPa·s or less, even more preferably 100 mPa·s or less, and most preferably 50 mPa·s or less, so that the effects of the aqueous cosmetic preparation's physical property stabilizer are more pronounced. The rotation speed when measuring with a rotational viscometer can be set appropriately between 1 and 100 rpm depending on the device and viscosity. For example, when using a TV-20 (cone-and-plate rotational viscometer) manufactured by Toki Sangyo Co., Ltd., a rotation speed of 5 rpm is used for measurements of 20 to 600 mPa·s.

[0031] Aqueous cosmetic preparations with a viscosity of more than 200 mPa·s are relatively less susceptible to unstable physical properties, and alternative solutions other than the stabilizer for aqueous cosmetic preparations of the present invention may also be selected, reducing the advantages of the stabilizer for aqueous cosmetic preparations.

[0032] The aqueous cosmetic of the present invention contains the above-mentioned aqueous cosmetic property stabilizer, and the content of β-1,3-1,6-glucan in the aqueous cosmetic is preferably 0.01 to 1 mass %, more preferably 0.05 to 0.5 mass %, even more preferably 0.12 to 0.35 mass %, and most preferably 0.15 to 0.32 mass %. If the amount is less than 0.01% by mass, the effect of the present invention will be insufficient, and if the amount is more than 1% by mass, the feeling when used may change, which is not preferable.

[0033] The aqueous cosmetic preparation of the present invention may contain any component that can be used in ordinary cosmetics in addition to the above-mentioned aqueous cosmetic property stabilizer, such as a surfactant, a chelating agent, a low-molecular-weight polyol, a plant-derived extract, a zinc compound, a thickener, an oil, a coloring matter, a pigment, an antibacterial agent, a moisturizer, a pH adjuster, an antioxidant, an ultraviolet absorber, a moisturizing component, an enzyme, or a fragrance.

[0093] Next, a method for producing the aqueous cosmetic preparation of the present invention will be described. The aqueous cosmetic preparation of the present invention can be produced according to a conventional method as long as the above-mentioned physical property stabilizer is contained in the aqueous phase. However, because this method can impart stability to physical properties without affecting the feel during use, it is preferable to pre-blend ingredients other than the physical property stabilizer of the present invention, emulsify the ingredients as needed, and then add the physical property stabilizer of the present invention.

[0094] Next, the method for stabilizing the physical properties of the aqueous cosmetic preparation of the present invention will be described. The method for stabilizing the physical properties of aqueous cosmetic preparations of the present invention involves adding a physical property stabilizer for aqueous cosmetic preparations containing β-1,3-1,6-glucan as an active ingredient. The active ingredient (solid content) of the physical property stabilizer is preferably added to the aqueous cosmetic preparation in an amount of 0.01 to 1 mass %, more preferably 0.05 to 0.5 mass %, even more preferably 0.12 to 0.35 mass %, and most preferably 0.15 to 0.32 mass %. In the method for stabilizing physical properties of the present invention, it is preferable to previously blend ingredients other than the above-mentioned stabilizer for aqueous cosmetics, emulsify the mixture as needed, and then add the stabilizer for aqueous cosmetics. By adding the stabilizer for aqueous cosmetics at a later stage, the effect of stabilizing physical properties can be further enhanced.

[0095] In the present invention, the effect of stabilizing emulsion is significant even for aqueous liquids with low viscosity, and therefore the method can be particularly suitably used as a "method for stabilizing emulsion." Furthermore, in the present invention, even if the aqueous liquid has a low viscosity, when it contains fine particles such as titanium oxide or zinc oxide, the effect of suppressing sedimentation and stabilizing dispersion is significant, and therefore the method can be particularly suitably used as a "dispersion stabilization method." Furthermore, in the present invention, even when stored under high temperature conditions exceeding 40°C, the effects are not lost and the physical properties can be maintained stable. [Example]

[0096] The present invention will be described in more detail below with reference to examples. In the following examples, "%" means "by mass" unless otherwise specified.

[0097] Preparation of Sample A Black yeast (accession number FERM BP-8391) was cultured on potato dextrose agar slant medium to obtain a stock strain, which was then inoculated into a 500 ml Erlenmeyer flask containing 100 ml of YM liquid medium (manufactured by Difco) and pre-cultured at 28°C for 3 days. This culture was transferred to a 30-liter fermenter containing 15 liters of Czapeak's medium (manufactured by Difco) and cultured at 28°C for 3 days. The culture was sterilized by heating at 90°C for 30 minutes, and then the cells were removed by centrifugation to obtain a culture supernatant, which was designated Sample A (sample A contained 1% by mass of β-1,3-1,6-glucan).

[0098] The β-1,3-1,6-glucan contained in this culture supernatant was a compound of general formula (1) in which the ratio of b to a was 0.85 and the mass-average molecular weight was 300,000. Subsequently, the obtained culture supernatant was spray-dried to obtain Sample B (Sample B contained 90% by mass of β-1,3-1,6-glucan).

[0099] Preparation of physical property stabilizers Samples A and B, xanthan gum, carbomer, and water were mixed together in the compositions shown in Table 1 below to obtain physical property stabilizers A to F of the present invention and physical property stabilizers G to J as comparative examples.

[0101] Physical property stability test <Emulsification stability> In Table 2 below, an oil phase consisting of component (A) and an aqueous phase consisting of component (B) were each heated to 70°C and mixed. Next, while stirring the aqueous phase with a homomixer, the oil phase was added little by little, and the aqueous phase was further cooled to 40°C while stirring at 3000 rpm for 5 minutes. If component (C) was required, component (C) was then slowly added and the mixture was stirred at 400 rpm for 30 minutes, yielding cosmetics a-v. The resulting cosmetics a-v were stored at 25°C or 50°C, and their emulsion stability was evaluated according to the following evaluation criteria. The results are shown in Table 3.

[0102] The viscosity was measured using a cone-plate type rotational viscometer (TV-20, manufactured by Toki Sangyo Co., Ltd.) at 25°C and a rotation speed of 5 rpm.

[0103] Furthermore, regarding the feel during use, 10 subjects (5 men and 5 women) thoroughly applied 0.1 g of any of the cosmetics a to v after storage to the back of their hands for a comparative evaluation. The comparison subject was an aqueous cosmetic product produced with the composition shown in Comparative Example 4 immediately after production, which was still in a stable emulsion state. The evaluation was quantified according to the following criteria, and the sum of the values ​​of the 10 subjects was taken as the evaluation score, The results are shown in Table 4, with ◎: 20 to 16 points, ○: 15 to 11 points, △: 10 to 6 points, ×: 5 points or less.

[0108] <Dispersion stability> Water, stabilizer A, xanthan gum, and sodium hyaluronate were mixed and stirred until homogeneous, as shown in Table 4. Next, titanium oxide or zinc oxide was added to each sample and stirred until uniformly dispersed, yielding aqueous cosmetics 2a to 2j. The resulting aqueous cosmetics 2a to 2j were stored at 40° C. for one month, and the dispersibility was evaluated according to the following evaluation criteria. The results are shown in Table 5. Furthermore, for the feel after use, 10 subjects (5 men and 5 women) thoroughly applied 0.1 g of any of the aqueous cosmetics 2a to 2j after storage to the back of their hands for a comparative evaluation. The comparison subject was an aqueous cosmetic produced with the composition shown in Comparative Example 8 immediately after production, which still had good dispersibility. The evaluation was quantified according to the following criteria, and the sum of the scores of the 10 subjects was taken as the evaluation score: The results are shown in Table 5, with ◎: 20 to 16 points, ○: 15 to 11 points, △: 10 to 6 points, ×: 5 points or less.
