Description

Aqueous cosmetic composition and cosmetic

[0001] The present invention relates to an aqueous cosmetic composition and a cosmetic containing the aqueous cosmetic composition.

[0002] Various pigments are used in cosmetics for the purposes of coloring, imparting texture, imparting a luxurious feel, etc. Among these, pearlescent pigments are sometimes used to impart gloss and luster (for example, Patent Document 1). Attempts have also been made to impart pearlescent luster without using pearlescent pigments (see Patent Documents 2 to 4).

[0003] On the other hand, sulfated polysaccharides derived from the freshwater cyanobacterium Aphanothece sacrum are known to have excellent moisturizing properties and have been proposed as cosmetic ingredients (see, for example, Patent Documents 5 and 6). It has also been reported that the use of these sulfated polysaccharides may reduce inflammation and restore the skin barrier function (see Non-Patent Document 1).

[0006] Stable dispersion of pigments in aqueous cosmetics is difficult, and conventional methods to ensure dispersibility include increasing the viscosity of the cosmetics, using various dispersants, and pretreating specific pigments. Because pearlescent pigments are particularly difficult to disperse, the invention described in Patent Document 1 ensures dispersibility and stability by using additives such as dispersants. However, when such measures are taken to improve pigment dispersibility and dispersion stability, problems arise, such as an increase in the viscosity of the entire cosmetic, limiting the cosmetic's tactile feel; the use of dispersants reduces the flexibility of the cosmetic composition; and the use of dispersants and pretreatment of the pigment increases production costs. In addition, the additives used in such measures are primarily petroleum-derived compounds, but petroleum-derived materials tend to be avoided in cosmetics intended for skin use due to concerns about safety, environmental friendliness, consumer image, and other factors. Meanwhile, as described in Patent Documents 2 to 4, attempts have been made to achieve a glossy appearance by incorporating various ingredients without using pigments such as pearlescent pigments themselves, but the gloss and color tone remain subject to improvement compared to when pigments are used.

[0007] The present invention has been made in view of the above-mentioned problems, and aims to provide a dispersant and a dispersion method that can stably disperse a dispersoid in an aqueous medium (dispersion medium) and stabilize the dispersed state without using additives such as petroleum-derived dispersants. More specifically, the present invention aims to provide an aqueous cosmetic composition that can stably disperse a dispersoid (specifically, a pigment, particularly a pearlescent pigment) used in a cosmetic composition at a low viscosity, stabilize the dispersed state, and suppress excessive sedimentation.

[0008] As a result of intensive research conducted by the present inventors to solve the above-mentioned problems, they have newly discovered that naturally occurring sulfated polysaccharides derived from Aphanothece sacrum function as dispersants, dispersion stabilizers, and anti-settling agents, thereby allowing dispersoids such as pigments to disperse well in aqueous media (dispersion media) and stabilizing the dispersed state, and that Aphanothece sacrum-derived sulfated polysaccharides exert their dispersing effect even at very low concentrations without excessively increasing the viscosity of cosmetic compositions, thereby completing the present invention.

[0009] The present invention provides the following: (1) A dispersant for aqueous cosmetic compositions, characterized in that it contains a Aphanothece sacrum-derived sulfated polysaccharide as an active ingredient. (2) Use of a Aphanothece sacrum-derived sulfated polysaccharide for stabilizing the dispersed state in an aqueous cosmetic composition containing a dispersoid and an aqueous medium as a dispersant. (3) A dispersion method, characterized in that an aqueous cosmetic composition containing a dispersoid and an aqueous medium as a dispersant further contains a Aphanothece sacrum-derived sulfated polysaccharide, thereby stabilizing the dispersed state. (4) An aqueous cosmetic composition containing a Aphanothece sacrum-derived sulfated polysaccharide, a colored pigment or a pearlescent pigment, and an aqueous medium, wherein the content of the Aphanothece sacrum-derived sulfated polysaccharide in the aqueous cosmetic composition is 0.03% by mass or more, the colored pigment or pearlescent pigment is stably dispersed in the aqueous medium, and the colored pigment or pearlescent pigment has not been surface-treated for hydrophilization. (5) The aqueous cosmetic composition according to (4) above, wherein the color pigment or pearl pigment has an average particle size of 2 μm to 250 μm. (6) The aqueous cosmetic composition according to (4) or (5) above, wherein the content of the Aphanothece sacrum-derived sulfated polysaccharide in the aqueous cosmetic composition is 0.03% by mass to 0.3% by mass. (7) A cosmetic comprising the aqueous cosmetic composition according to any one of (4) to (6) above.

[0010] The present invention also provides the following inventions: (2-1) An aqueous cosmetic composition containing a Aphanothece sacrum-derived sulfated polysaccharide, a colored pigment or pearlescent pigment, and an aqueous medium, wherein the content of the Aphanothece sacrum-derived sulfated polysaccharide in the aqueous cosmetic composition is 0.03% by mass or more, and the colored pigment or pearlescent pigment has not been surface-treated for hydrophilization. (2-2) The aqueous cosmetic composition of (2-1) above, wherein the average particle size of the colored pigment or pearlescent pigment is 2 μm to 250 μm. (2-3) The aqueous cosmetic composition of (2-1) or (2-2) above, wherein the content of the Aphanothece sacrum-derived sulfated polysaccharide in the aqueous cosmetic composition is 0.03% by mass to 0.3% by mass. (2-4) A cosmetic containing the aqueous cosmetic composition of any one of (2-1) to (2-3) above.

[0011] According to the present invention, it is possible to stably disperse dispersoids in an aqueous medium (dispersion medium) and stabilize the dispersion state. Therefore, it is possible to obtain an aqueous cosmetic in which the pigment is well dispersed and excessive pigment sedimentation is prevented without increasing the viscosity of the entire cosmetic. Furthermore, since the Aphanothece sacrum-derived sulfated polysaccharides used in combination with the pigment are algae-derived components, they can be used safely and securely compared to synthetic components derived from petroleum raw materials. Furthermore, since the Aphanothece sacrum-derived sulfated polysaccharides themselves are expected to have moisturizing effects, skin barrier effects, anti-inflammatory effects, etc., they can be used not only as a dispersant and anti-settling agent but also to improve and enhance various skin functions and conditions.

[0012] The present invention will be described in further detail below. However, the present invention is not limited to the embodiments shown below. In this specification, unless otherwise specified, "parts" and "%" mean "parts by mass" and "% by mass". In this specification, unless otherwise specified, "XX or more and YY or less" or "XX to YY" means a numerical range including the lower and upper limit values, which are the endpoints. When a numerical range is described in stages, the upper and lower limit values ​​of each numerical range can be combined arbitrarily.

[0013] (Dispersant for aqueous cosmetic composition) The dispersant in this embodiment contains a Porphyra sacrum-derived sulfated polysaccharide as an active ingredient, and functions as a dispersant in an aqueous cosmetic composition, i.e., a cosmetic composition having an aqueous medium. The Porphyra sacrum-derived sulfated polysaccharide and the aqueous cosmetic composition are the same as those described below.

[0014] (Use of Aphanothece sacrum-derived sulfated polysaccharides) The use of Aphanothece sacrum-derived sulfated polysaccharides in this embodiment aims to stabilize the dispersion state in an aqueous cosmetic composition containing a dispersoid and an aqueous medium as a dispersion medium. The Aphanothece sacrum-derived sulfated polysaccharides, the aqueous medium, and the aqueous cosmetic composition are the same as those described below. The dispersoid is not particularly limited as long as it is a component used in cosmetics, and may be a solid component or a liquid component. In this embodiment, the Aphanothece sacrum-derived sulfated polysaccharides function as a dispersant in the aqueous medium, thereby enabling good and stable dispersion of even dispersoids that are difficult to disperse in the aqueous medium. Specific examples of dispersoids include solid components such as color pigments and pearl pigments, and liquid components such as oily components that are liquid at room temperature. The color pigments, pearl pigments, and oily components are the same as those described below.

[0015] (Dispersion Method) In the dispersion method of this embodiment, an aqueous cosmetic composition containing a dispersoid and an aqueous medium as a dispersion medium further contains a Amorphophallus sacrum-derived sulfated polysaccharide, thereby stabilizing the dispersion state. The dispersoid is as described above, and the Amorphophallus sacrum-derived sulfated polysaccharides, aqueous medium, and aqueous cosmetic composition are the same as those described below. In the method of this embodiment, the Amorphophallus sacrum-derived sulfated polysaccharides may be added to a composition already containing the dispersoid and dispersion medium, or the dispersoid and Amorphophallus sacrum-derived sulfated polysaccharides may be added simultaneously to a composition containing a dispersion medium, or the dispersoid may be added to a composition containing a dispersion medium after the Amorphophallus sacrum-derived sulfated polysaccharides have been added.

[0016] (Aqueous Cosmetic Composition) The aqueous cosmetic composition of the present invention (hereinafter sometimes referred to as "aqueous cosmetic composition," "cosmetic composition," or "composition") contains a sulfated polysaccharide derived from Aphanothece sacrum, a color pigment or pearl pigment, and an aqueous medium. Each component will be described below.

[0017] Aphanothece sacrum-derived sulfated polysaccharides (hereinafter sometimes simply referred to as "sulfated polysaccharides" or "polysaccharides") are derived from the freshwater cyanobacterium Aphanothece sacrum obtained naturally or through aquaculture (culture), and are a type of sulfated polysaccharide generally having an average molecular weight of 2,000,000 or more. Specifically, they are sugar derivatives having a repeating structure of sugar chain units in which sugar structures having hexose structures and sugar structures having pentose structures are linked in a linear or branched chain via α-glycosidic bonds or β-glycosidic bonds, the sugar chain units containing sulfated sugars, and in which 2.7 or more hydroxyl groups per 100 hydroxyl groups in the sugar chain units are sulfated, or in which sulfur accounts for 1.5% by weight or more of the total elements.

[0018] Specific examples of sulfated polysaccharides include sulfated muramic acid and sulfated N-acetylmuramic acid.

[0019] The sulfated polysaccharides contain at least glucose, galactose, mannose, galactosamine, xylose, arabinose, glucuronic acid, galacturonic acid, fucose, and rhamnose, and may have a functional group selected from the group consisting of at least sulfate, lactic acid, and methyl groups attached to any bonding position in these sugar structures. The sulfate group, which is characteristic of the Aphanothece saccharin-derived sulfated polysaccharides, is preferably contained in an amount of 3 to 20% by mass, more preferably 5 to 15% by mass, and even more preferably 8 to 12% by mass.

[0020] A portion of the sugar structure constituting the sulfated polysaccharide may further be bound to a peptide or lipid.

[0021] The molar ratio of the main sugar structures constituting the sulfated polysaccharide may be arabinose 1.1:fucose 3.7:rhamnose 15.4:xylose 17.0:mannose 10.5:galactose 12.3:galacturonic acid 4.6:glucuronic acid 4.7:glucose 28.8:galactosamine 2.03. The types of sugar structures (monosaccharides) constituting the sulfated polysaccharide may be 5 or more, 7 or more, 8 or more, or 10 or more.

[0022] The average molecular weight of the sulfated polysaccharide is, for example, 500,000 or more, 800,000 or more, 1,000,000 or more, 2,000,000 or more, 5,000,000 or more, 10,000,000 or more, 20,000,000 or more, and 30,000,000 or less, 28,000,000 or less, 25,000,000 or less, 22,000,000 or less, etc. Consistent combinations thereof are also acceptable, such as 1,000,000 to 30,000,000, 5,000,000 to 28,000,000, 10,000,000 to 25,000,000, 20,000,000 to 22,000,000, etc.

[0023] The sulfated polysaccharides may be extracted, isolated, and purified from A. sacchariflorus. The method for extracting the sugar derivatives from A. sacchariflorus is not particularly limited, and examples include conventional methods such as those described in Patent Document 5. Specifically, for example, the following method is used: An appropriate amount of A. sacchariflorus is frozen and thawed, then washed with water to remove water-soluble pigments. The fat-soluble pigments are then removed by stirring overnight with an organic solvent such as ethanol. After the organic solvent is separated from the A. sacchariflorus from which the pigments have been removed, the solution is dissolved in, for example, a 0.1-0.6 N aqueous sodium hydroxide solution, heated to, for example, 40-80°C, and stirred for, for example, 5-12 hours. The aqueous solution of the sugar derivative extracted by this procedure is neutralized, for example, with concentrated hydrochloric acid. Desalting may or may not be performed by immersion in, for example, 60-80% isopropyl alcohol. The sugar derivative is then precipitated in a gel form by pouring it into, for example, 100% isopropanol while stirring, followed by drying with hot air. Drying with hot air may be performed at, for example, 85 to 100°C or higher for, for example, 6 to 24 hours. The extracted and precipitated sugar derivatives may be purified by centrifugation, filtration, alcohol washing, etc. Furthermore, before extracting the sugar derivatives from Aphanothece sacrum, the Aphanothece sacrum may be frozen and then thawed, followed by a step of removing the pigments.

[0024] Commercially available sulfated polysaccharides may be used, such as "SACRAN" (registered trademark) manufactured by Green Science Materials (GSM) and "SACRANEX" (registered trademark) manufactured by DIC Group.

[0025] Furthermore, as long as the effects of the present invention are achieved, the sulfated polysaccharides may be contained in a crushed dried product of A. sacchariflorus (hereinafter referred to as "crushed dried A. sacchariflorus"). Accordingly, the present invention can also provide a cosmetic composition containing, as an active ingredient, a crushed dried product of A. sacchariflorus containing sulfated polysaccharides. The crushed dried product of A. sacchariflorus containing the sugar derivatives may be, for example, a crushed freeze-dried product of A. sacchariflorus containing the sugar derivatives, a crushed sun-dried product of A. sacchariflorus containing the sugar derivatives, or a crushed hot-air-dried product of A. sacchariflorus containing the sugar derivatives. Any one of these may be used alone, or a combination of two or more may be used. Crushed dried products of A. sacchariflorus containing sulfated polysaccharides can all be prepared by conventional methods. For example, a freeze-dried crushed product of A. saccharinum containing the sugar derivative can be prepared by freezing A. saccharinum while it still contains water in a low-temperature freezer, removing the water contained within the algae by vacuum freeze-drying to obtain freeze-dried A. saccharinum, and then crushing it (e.g., by grinding it with a mortar and pestle, or by powdering it with a grinding device), which can then be suspended in an appropriate solvent or solution.

[0026] Furthermore, as long as the effects of the present invention are achieved, the sulfated polysaccharides may be contained in an extract of Aphanothece sacrum (hereinafter referred to as "Aphanothece sacrum extract"). Thus, the present invention can also provide a cosmetic composition containing, as an active ingredient, an Aphanothece sacrum extract containing sulfated polysaccharides. The Aphanothece sacrum extract containing sulfated polysaccharides can be prepared, for example, by the method described above.

[0027] In the cosmetic composition of the present invention, the content of the sulfated polysaccharide is 0.030% by mass or more, preferably 0.035% by mass to 0.300% by mass, more preferably 0.040% by mass to 0.250% by mass, even more preferably 0.050% by mass to 0.200% by mass, and particularly preferably 0.055% by mass to 0.100% by mass. Furthermore, the content of the sulfated polysaccharide relative to the color pigment or pearl pigment described below is not particularly limited and can be determined appropriately depending on the type of cosmetic product desired. In the case of cosmetics that are not intended to significantly color target areas such as the skin, for example, skin care items such as lotions, the content of the sulfated polysaccharide relative to 1 part by mass of the pigment is preferably 3 to 200 parts by mass, more preferably 4 to 150 parts by mass, and particularly preferably 5 to 100 parts by mass. On the other hand, in the case of cosmetics intended to color a target area and develop a strong color, for example, point makeup items such as liquid rouge, and base makeup items such as liquid foundation, BB cream, and makeup base, the sulfated polysaccharide is preferably contained in an amount of 0.0005 to 20 parts by mass, more preferably 0.001 to 10 parts by mass, and particularly preferably 0.003 to 5 parts by mass, per part by mass of the pigment. This preferred ratio of pigment to sulfated polysaccharide is the same for both cosmetic compositions and the cosmetics described below.

[0028] Color pigments or pearl pigments: In this specification, a color pigment is a component added for the purpose of coloring a cosmetic product, and is a pigment that absorbs light of a specific wavelength to exhibit a color. On the other hand, a pearl pigment is a component added mainly for the purpose of imparting a luster (and color) similar to that of shellfish such as pearls, and is mainly composed of an inorganic compound, and may be an inorganic compound to which a coloring component is attached or coated. The color pigment is not particularly limited as long as it can be used in cosmetics, and examples thereof include inorganic white pigments such as titanium oxide, titanium dioxide, and zinc oxide; inorganic red pigments such as iron oxide (red iron oxide) and iron titanate; inorganic brown pigments such as γ-iron oxide; inorganic yellow pigments such as yellow iron oxide and ochre; inorganic black pigments such as black iron oxide and low-order titanium oxide; inorganic purple pigments such as manganese violet and cobalt violet; inorganic green pigments such as chromium oxide, chromium hydroxide, and cobalt titanate; inorganic blue pigments such as ultramarine and iron blue; aluminum powder, copper powder, and the like. and synthetic organic pigments such as zirconium, barium, or aluminum lake, such as Red No. 201, Red No. 202, Red No. 204, Red No. 205, Red No. 220, Red No. 226, Red No. 228, Red No. 405, Orange No. 203, Orange No. 204, Yellow No. 205, Yellow No. 401, Blue No. 404, Red No. 3, Red No. 104, Red No. 106, Red No. 227, Red No. 230, Red No. 401, Red No. 505, Orange No. 205, Yellow No. 4, Yellow No. 5, Yellow No. 202, Yellow No. 203, Green No. 3, and Blue No. 1. The pearlescent pigment is not particularly limited as long as it can be used in cosmetics. The surface of inorganic granular powders such as mica, synthetic mica, synthetic phlogopite, glass powder, silica, alumina, etc., can be coated with a colorant such as titanium dioxide, iron oxide, silicon oxide, Prussian blue, chromium oxide, chromium hydroxide, gold, silver, carmine, or the above-mentioned coloring pigments, and specific examples include titanium oxide-coated mica, titanium oxide-coated bismuth oxychloride, titanium oxide-coated talc, colored titanium oxide-coated mica, bismuth oxychloride, etc.

[0029] In the present invention, the use of a Porphyra sacchariflora-derived sulfated polysaccharide in combination with the pigments allows these pigments to disperse well in aqueous media, and therefore the colored pigments or pearlescent pigments do not need to have their surfaces hydrophilized. Applying a pretreatment such as hydrophilization to a pigment in advance complicates the process and increases production and raw material costs, so using a pigment that has not been hydrophilized can reduce the effort and cost.

[0030] The average particle size of the color pigment or pearl pigment is not particularly limited, but is preferably 2 to 250 μm.

[0031] The content of the color pigment or pearl pigment is not particularly limited and can be determined appropriately depending on the desired color and texture, but it is generally used in the range of 0.00001% by mass to 0.1% by mass with respect to the entire composition.

[0032] In the present invention, the aqueous medium may be water, a water-miscible organic solvent, or a combination thereof. The water may be any of tap water, purified water, hard water, soft water, natural water, deep sea water, electrolytic alkaline ionized water, electrolytic acidic ionized water, ionized water, and cluster water. The organic solvent may be any known solvent that can be used in cosmetics, and examples thereof include lower alcohols such as ethanol, 2-propanol (isopropyl alcohol), butanol, and isobutyl alcohol; glycols such as propylene glycol, 1,3-butylene glycol, diethylene glycol, dipropylene glycol, and isopentyl diol; glycol ethers such as diethylene glycol monoethyl ether (ethoxydiglycol), ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, triethylene glycol monoethyl ether, diethylene glycol diethyl ether, diethylene glycol dibutyl ether, propylene glycol monoethyl ether, and dipropylene glycol monoethyl ether; glycol ether esters such as ethylene glycol monoethyl ether acetate, diethylene glycol monoethyl ether acetate, and propylene glycol monoethyl ether acetate; glycol esters such as diethoxyethyl succinate and ethylene glycol disuccinate; benzyl alcohol, benzyloxyethanol, propylene carbonate, dialkyl carbonate, acetone, ethyl acetate, and N-methylpyrrolidone.

[0033] Although the aqueous cosmetic composition of the present invention is an aqueous cosmetic composition containing a color pigment or pearl pigment and an aqueous medium, the viscosity of the composition is not excessively increased by the use of a sulfated polysaccharide derived from Aphanothece sacrum as a dispersant, and the composition can be made to have a low viscosity. The viscosity of the aqueous cosmetic composition of the present invention is not particularly limited and can be determined appropriately depending on the intended use and formulation of the cosmetic, but is preferably 5 to 100 mPa·s, more preferably 10 to 95 mPa·s, and even more preferably 15 to 90 mPa·s. Having the viscosity of the cosmetic composition within the above range allows for a wider range of choice in the use and formulation of the cosmetic, and allows for greater freedom in designing the cosmetic composition.

[0034] The aqueous cosmetic composition of the present invention can be used in various cosmetic applications, such as skin cosmetics, hair cosmetics, and makeup cosmetics, and its formulation is not limited as long as the effects of the present invention can be obtained. Examples of formulations include ampoules, capsules, pills, tablets, powders, granules, solids, liquids, gels, foams, emulsions, sheets, mists, sprays, and other suitable forms for use, such as 1) pharmaceuticals, 2) quasi-drugs, and 3) topical or whole-body skin cosmetics (for example, basic cosmetics such as lotions, toners, emulsions, creams, ointments, lotions, serums, beauty essences, and packs; facial cleansers and skin cleansers; massage agents, cleansing agents, hair removers, depilatories, shaving treatments, aftershave lotions, pre-shave lotions, shaving creams; sunscreens, makeup bases, concealers, foundations, face powders, lipsticks, blushers, eyeshadows, eyeliners, mascaras, and other cosmetic products). makeup cosmetics such as ebrows; perfumes, nail polish, nail enamel, nail enamel remover, poultices, plasters, tapes, sheets, patches, aerosols, etc.); 4) medicinal and / or cosmetic preparations to be applied to the scalp and hair (for example, shampoos, rinses, hair treatments, pre-hair treatments, permanent solutions, hair dyes, hair styling products, hair tonics, hair growth and care products, poultices, plasters, tapes, sheets, patches, aerosols, etc.); 5) bath additives to be added to bathwater; 6) other products such as underarm odor prevention agents, deodorants, deodorants, antiperspirants, sanitary products, sanitary cotton, wet tissues, toothpastes, mouth fresheners, mouthwashes, dishwashing detergents, etc.

[0056] (Cosmetics) The aqueous cosmetic composition of the present invention can be used as a cosmetic after further incorporating necessary components. Necessary components include the optional components described above in the description of the aqueous cosmetic composition. The viscosity of the cosmetic of the present invention is not particularly limited and can be determined appropriately depending on the intended use and formulation. Meanwhile, since the aqueous cosmetic composition of the present invention is a low-viscosity aqueous composition capable of dispersing pigments well, it is possible to produce a cosmetic product with a relatively low viscosity as a final product. Specifically, the viscosity is preferably 5 to 300 mPa·s, more preferably 10 to 250 mPa·s, and even more preferably 15 to 200 mPa·s. Having the viscosity of the cosmetic composition within the above range allows for a wider range of applications and formulations to be selected, and allows for greater freedom in composition design.

[0057] The present invention will be specifically described below using examples, but the present invention is not limited to these examples.

[0058] Example 1 0.8 g of a 0.5% by mass aqueous solution of Aphanothece sacrum polysaccharides as a dispersant (0.037% by mass in terms of Aphanothece sacrum polysaccharides relative to the total mass of the composition), 4 mg of Chione (registered trademark) Electric Sunset SK90D as a pigment, and 10 g of base B1 as a base having a composition described below were all placed in a glass bottle, and stirred with a magnetic stirrer at room temperature for 2 to 3 hours until a vortex was formed, thereby obtaining the cosmetic composition of Example 1.

[0059] [Examples 2 to 22, Comparative Examples 1 to 39] Aqueous cosmetic compositions of Examples 2 to 22 and Comparative Examples 1 to 39 were obtained in the same manner as in Example 1, except that the dispersant (type, amount added), pigment, or base was changed to those shown in Tables 1 to 12.

[0060] The abbreviations in Tables 1 to 12 have the following meanings: The dispersants used in the comparative examples instead of the polysaccharides derived from Aphanothece sacrum were all 1.0% aqueous solutions. SK90D: "Chione (registered trademark) Electric Sunset SK90D" (trade name, manufactured by Sun Chemical Co.) Y30D: "Flamenco (registered trademark) Summit Gold Y30D" (trade name, manufactured by Sun Chemical Co.) C37-8073: "SunCROMA (registered trademark) D&C Red 30AL Lake C37-8073" (trade name, manufactured by Sun Chemical Co.) Base B1: ethanol 6%, butylene glycol 5%, trehalose 0.03%, sodium hyaluronate 0.01%, lauroyl glutamate di(phytosteryl / octyldodecyl) 0.02%, PEG-60 hydrogenated castor oil Base B2: A solution consisting of 0.5%, methylparaben, sodium citrate, citric acid, and trace amounts of tocopherol, and the balance being water. Base B2: A solution consisting of 5%, butylene glycol, 0.03%, trehalose, 0.01%, sodium hyaluronate, 0.5%, di(cholesteryl / behenyl / octyldodecyl) lauroyl glutamate, 0.3%, triethylhexanoin, 0.9%, PEG-50 hydrogenated castor oil triisostearate, 0.23%, ceteth-20, 0.88%, methylparaben, propylparaben, phenoxyethanol, sodium malate, malic acid, and trace amounts of tocopherol, and the balance being water. Base B3: A solution consisting of purified water.

[0061] The cosmetic compositions obtained in each example were subjected to the following evaluations and measurements. (Evaluation of Dispersibility) The cosmetic compositions placed in glass bottles were left to stand at room temperature, and the state of dispersion after two weeks was evaluated by visual observation according to the following criteria. A grade of B or higher was considered to be acceptable. The results are also shown in Tables 1 to 12. A: Well dispersed B: Sufficiently dispersed C: Dispersed but with some problems D: Sedimentation

[0062] (Viscosity Measurement) The viscosity (initial viscosity) of each of the compositions obtained in the Examples and Comparative Examples was measured using a digital Brookfield viscometer ("Digital Viscometer DV2T", manufactured by Eiko Seiki Co., Ltd.). An SC4-30 rotor was used, and measurements were performed at a rotation speed of 30 rpm and a measurement temperature of 25°C, with the viscosity measured 3 minutes after the start of measurement. Note that, for Comparative Examples 31 and 32 only, measurements could not be performed at 30 rpm due to over-torque, so the rotation speed was changed to 5 rpm and measurements were performed. The results are also shown in Tables 1 to 12.

[0075] From the above results, it was confirmed that the aqueous cosmetic compositions of Examples 1 to 22 according to the present invention had excellent pigment dispersibility without a significant increase in viscosity. On the other hand, the aqueous cosmetic compositions of Comparative Examples 1 to 39, which did not use Aphanothece sacrum-derived sulfated polysaccharides or contained small amounts of Aphanothece sacrum-derived sulfated polysaccharides, either showed a significant increase in viscosity or were unable to disperse pigments. Therefore, it was confirmed that by using a color pigment or pearl pigment in combination with a certain amount or more of Aphanothece sacrum-derived sulfated polysaccharides, cosmetic compositions with excellent pigment dispersibility in low-viscosity aqueous media can be obtained.

[0076] [Examples 23 to 29, Comparative Example 40] The aqueous cosmetic compositions of Examples 23 to 29 and Comparative Example 40 were obtained in the same manner as in Example 1, except that the dispersant (type, amount added) and base were changed to those shown in Tables 13 and 14.

[0077] In Tables 13-14, "Base B4" is the lotion "Kiehl's DS Clearly Bright Treatment Toner" (product name, manufactured by NLO, purchased in April 2023). Base B4 contains 3-O-ethyl ascorbic acid, dipotassium glycyrrhizinate, salicylic acid, purified water, proxylene, propylene glycol, peony extract, tangerine peel extract, lavender oil, concentrated glycerin, polyoxyethylene methyl glucoside, 1,3-butylene glycol, synthetic phlogopite, titanium oxide, dipropylene glycol, anhydrous ethanol, sodium benzoate, tertiary butanol, polyoxyethylene polyoxypropylene decyl tetraether, xanthan gum, citric acid, sodium citrate, disodium edetate, and phenoxyethanol. The lotion used as the base already contains the pigments synthetic phlogopite and titanium oxide.

[0078] Using the obtained cosmetic compositions of each example, dispersibility and viscosity were evaluated in the same manner as in Example 1. The results are shown in Tables 13 and 14.

[0079]

[0080]

[0081] From the above results, it was confirmed that the aqueous cosmetic compositions of Examples 23 to 29 according to the present invention had excellent pigment dispersibility without a significant increase in viscosity. On the other hand, the aqueous cosmetic composition of Comparative Example 40, which did not use the Aphanothece sacrum-derived sulfated polysaccharide, was unable to maintain the pigment dispersed.
