Description

Aqueous dispersion and cosmetic containing same

[0001] The present invention relates to an aqueous dispersion containing hydrophobized titanium dioxide fine particles, and to a cosmetic preparation containing this aqueous dispersion.

[0002] In general, fine inorganic powders such as titanium oxide and zinc oxide are widely used in sunscreen cosmetics to improve transparency and enhance UV-shielding effects (Patent Document 1). However, as the surface area of ​​these inorganic powders increases, the interactions between the particles become stronger, resulting in the powders being prone to aggregation.

[0003] These fine inorganic powders may be subjected to hydrophobic surface treatment for the purpose of blending them into the oil phase of cosmetics or for improving their water resistance. By blending such hydrophobically surface-treated powders, it is expected that the UV-shielding effect can be maintained even when wetted with water (Patent Documents 2 and 3). On the other hand, when blending fine inorganic powders into an aqueous phase, powders that have been hydrophilically surface-treated with silica or the like may be used. However, these hydrophilized powders have issues with water resistance and usability. Furthermore, as a method for dispersing hydrophobized powders in water, aqueous dispersions of hydrophobized titanium oxide fine particles using polyether-modified silicone have been investigated. However, these titanium oxide aqueous dispersions have issues with water resistance and usability (Patent Document 4).

[0004] Furthermore, a technique for obtaining dispersible powders by surface-treating powders with silicone surfactants is known. However, there has been insufficient research into the dispersibility and water resistance of hydrophobically treated inorganic powders (Patent Document 5).

[0005] In addition, dispersions containing nonionic surfactants have been investigated, but sufficient dispersibility has not been achieved (Patent Document 6). For these reasons, there has been a demand for dispersions that have good long-term stability and provide a good feel when incorporated into cosmetics.

[0006] Japanese Patent Application Laid-Open No. 2006-1886 Japanese Patent Application Laid-Open No. 2014-201569 International Publication No. 2016 / 178380 International Publication No. 2015 / 125622 Japanese Patent Application Laid-Open No. 2020-002031 Japanese Patent Application Laid-Open No. 7-247119

[0007] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an aqueous dispersion of a fine inorganic powder that has excellent dispersibility in aqueous media and high dispersion stability, and to provide a cosmetic that incorporates this aqueous dispersion and has high stability, transparency, a feeling of use (non-stickiness), and excellent water resistance.

[0008] As a result of intensive research to achieve the above object, the present inventors have found that even a dispersion of titanium oxide fine particles, which is difficult to disperse, can be used to obtain an aqueous dispersion that is excellent in dispersibility in aqueous media, has high stability (viscosity stability), has long-term stability, and is excellent in feel when used (non-sticky) and water resistance. The present inventors have found that when this dispersion is used in cosmetics, the resulting cosmetics are easy to dispense and have excellent transparency, feel when used, and water resistance, and have completed the present invention.

[0009] Accordingly, the present invention provides the following aqueous dispersions and cosmetics. 1. An aqueous dispersion comprising: (a) 10 to 70 mass% hydrophobic titanium oxide microparticles, the titanium oxide particles having a number-average primary particle diameter of 8 to 200 nm as determined by image analysis of transmission electron micrographs, and hydrophobized with silicone; (b) 1.0 to 30 mass% aqueous component having two or more alcoholic hydroxyl groups; (c) 1.0 to 20 mass% polyglycerin-modified silicone soluble in component (b); and (d) 8 to 82 mass% water. 2. The aqueous dispersion according to 1, wherein component (a) is hydrophobized titanium oxide microparticles obtained by hydrophobizing hydrated silica-coated titanium oxide particles. 3. The aqueous dispersion according to 1 or 2, wherein the silicone in component (a) is hydrogen dimethicone. 4. The aqueous dispersion according to any one of 1 to 3, wherein component (b) is an aqueous component having two alcoholic hydroxyl groups. 5. The aqueous dispersion according to any one of 1 to 4, wherein component (c) is a component that is insoluble in component (d). 6. The aqueous dispersion according to any one of 1 to 5, wherein component (c) is polyglyceryl-3 disiloxane dimethicone. 7. The aqueous dispersion according to any one of 1 to 6, wherein the mass ratio (c) / (b) of the content of component (c) to the content of component (b) is 0.2 to 0.9. 8. The aqueous dispersion according to any one of 1 to 7, wherein the total content of components (a), (b), (c), and (d) is 90 mass% or more relative to the entire aqueous dispersion. 9. 10. An aqueous dispersion comprising: (a) 10 to 70% by mass of hydrophobic titanium oxide fine particles, wherein the titanium oxide particles are selected from hydrous silica-coated titanium oxide particles and hydrous silica- and aluminum hydroxide-coated titanium oxide and are hydrophobized with a silicone selected from triethoxycaprylylsilane, dimethyl silicone, hydrogen dimethicone, triethoxysilylethyl polydimethylsiloxyethyl dimethicone, and triethoxysilylethyl polydimethylsiloxyethylhexyl dimethicone, and have a number-average primary particle diameter of 8 to 200 nm as measured by image analysis of transmission electron micrographs; (b) 1.0 to 30% by mass of one or more selected from BG (display name), DPG (display name), and glycerin; (c) 1.0 to 20% by mass of polyglyceryl-3 disiloxane dimethicone; and (d) 8 to 82% by mass of water. 10. A cosmetic comprising the aqueous dispersion according to any one of 1 to 9.

[0010] According to the present invention, an aqueous dispersion can be obtained that has excellent dispersibility in aqueous media, high stability (viscosity stability), long-term stability, and excellent feel in use (non-sticky) and water resistance. When this aqueous dispersion is used as a dispersion in a cosmetic, it is easy to dispense and can provide a cosmetic that is excellent in transparency, feel in use, and water resistance.

[0011] The present invention will be described in detail below. In the present invention, ingredient names may be written in cosmetic name or International Nomenclature of Cosmetic Ingredients (INCI). When the cosmetic name and INCI correspond to each other, the English name may be omitted.

[0012] [Component (a)] Component (a) of the present invention is hydrophobized titanium oxide fine particles having a number-average primary particle diameter of 8 to 200 nm as determined by image analysis of transmission electron micrographs, in which titanium oxide particles have been hydrophobized with silicone, and can be used alone or in combination of two or more. Titanium oxide fine particles used as an ultraviolet scattering agent that has an ultraviolet blocking effect of titanium oxide are generally any raw material that can be incorporated into cosmetics, and may be a composite powder of two or more types with zinc oxide and / or cerium oxide, or a composite powder with other powders.

[0013] Titanium oxide fine particles may be surface-treated with silica, hydrous silica, alumina, aluminum hydroxide, etc. before hydrophobization treatment in order to reduce cohesion or suppress the activity of the powder. Note that alumina and aluminum hydroxide are not preferred as surface treatment agents when blended into cosmetics, as they may inhibit the swelling of the water-soluble polymer compound used in combination or may reduce water resistance. Hydrous silica-coated titanium oxide particles, which have been surface-treated with hydrous silica, are preferred because they suppress the activity of the powder and are less likely to inhibit the swelling of the water-soluble polymer. Note that "coated" refers to covering part or all of the titanium oxide particles.

[0014] In the present invention, the titanium oxide particles are hydrophobized with silicone. Examples of the silicone used for the hydrophobization treatment include silanes or silylating agents such as triethoxycaprylylsilane (manufactured by Shin-Etsu Chemical Co., Ltd.: AES-3083), dimethyl silicones (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-96AK series), methyl hydrogen polysiloxanes such as hydrogen dimethicone (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-99P, KF-9901, etc.), and branched silicones such as triethoxysilylethyl polydimethylsiloxyethylhexyl dimethicone and triethoxysilylethyl polydimethylsiloxyethylhexyl dimethicone (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-9908, KF-9909, etc.). In particular, a component containing one or more selected from triethoxycaprylylsilane, triethoxysilylethyl polydimethylsiloxyethyl dimethicone, triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone, and hydrogen dimethicone is preferable in terms of the hydrophobic treatment and dispersibility with component (c). The hydrophobic treatment method is not particularly limited, and can be performed by a known method. For example, a wet treatment method, a dry treatment method, a gas phase method, etc. can be mentioned.

[0015] Commercially available titanium dioxide fine particles that have undergone these surface treatments can also be used. For example, they are commercially available under the trade names MT-01, 02, 050OTS, 100Z, 100TV, 100SAS, 150EX, 200ST, 500SAM, 505SAS, 700Z, and 700BS (manufactured by Teika Co., Ltd.), ST-455, 455WS, 457ECS, 457SA, 495M, and 455FA (manufactured by Titanium Kogyo Co., Ltd.), and STR-100A-LP, 100C-LP, 100W-LP, 100C-LF, and 40-LP (manufactured by Sakai Chemical Industry Co., Ltd.). An example of a hydrophobic titanium dioxide fine particle obtained by hydrophobizing hydrous silica-coated titanium dioxide particles is STR-100W-LP. Note that it is preferable that a dispersion in which particles are previously dispersed in an oil agent is not included as component (a).

[0016] The number-average primary particle diameter of component (a) measured by image analysis of a transmission electron microscope photograph is 8 to 200 nm, preferably 10 to 150 nm. If it exceeds 200 nm, the UV protection function will be reduced and white residue will remain. If the particle diameter is less than 8 nm, the product may feel too dry and have a poor feel when used. The average primary particle diameter of component (a) of the present invention is the average diameter of 200 particles measured by image analysis of a transmission electron microscope photograph. If the powder is not spherical, the average primary particle diameter is defined as the average value of the minor axis of the particles. Examples of the shape of the fine particle titanium dioxide include spindle-shaped, needle-shaped, straw-like, rectangular, approximately spherical, and rod-shaped.

[0017] The content of component (a) in the aqueous dispersion is 10 to 70% by mass, and from the viewpoint of usability, it is preferably 10 to 65% by mass, more preferably 15 to 60% by mass, and even more preferably 20 to 55% by mass. If it is less than 10% by mass, a sufficient UV-shielding effect cannot be obtained, and if it is blended in more than 70% by mass, the spreadability during use may be deteriorated, the stability of the dispersion over time may be reduced, and the viscosity may increase.

[0018] [Component (b)] The component (b) of the present invention is an aqueous component having two or more alcoholic hydroxyl groups, i.e., a component that dissolves in water at 25°C, and can be used alone or in combination of two or more. Specifically, sugar alcohols such as sorbitol (INCI), maltose (INCI), xylitol (INCI), glucose (INCI), glyceryl glucoside (INCI), sodium chondroitin sulfate (display name (INCI: Sodium Chondroitin Sulfate)), methyl gluceth-10 (INCI), methyl gluceth-20 (INCI), hyaluronic acid, phosphatidylglycerol, and phosphatidylinositol, BG (display name (INCI: Butylene Glycol)), PG (display name (INCI: Propylene Glycol)), DPG (display name (INCI: Dipropylene Glycol)), and the like. Glycol), pentylene glycol (INCI), 1,10-decanediol (INCI), octanediol (INCI), 1,2-hexanediol (INCI), and other glycols; and polyhydric alcohols such as erythritol (INCI), glycerin (INCI), diglycerin (INCI), and polyethylene glycol. Of these, glycols such as BG (butylene glycol) and DPG (dipropylene glycol), and polyhydric alcohols such as glycerin are preferred because they dissolve in water in any proportion, and furthermore, they offer a good feel when used and are versatile as a cosmetic ingredient. Glycols having two alcoholic hydroxyl groups in the molecule are particularly preferred.

[0019] The content of component (b) in the aqueous dispersion is 1.0 to 30% by mass, preferably 5 to 25% by mass, and more preferably 7 to 15% by mass from the viewpoint of water resistance. From the viewpoint of stability over time, 15 to 25% by mass is even more preferable, and 15 to 20% by mass is particularly preferable. If the content is less than 1.0% by mass, the stability of the dispersion deteriorates. If the content exceeds 30% by mass, the cosmetic product feels sticky when used. Furthermore, component (b) may inhibit the orientation of component (c) (described below) in component (a), resulting in an increase in viscosity or impaired dispersibility in an aqueous medium. By incorporating component (b), component (c) can be uniformly oriented on the surface of component (a).

[0020] [Component (c)] Component (c) of the present invention is a polyglycerin-modified silicone that dissolves in component (b) and can be used alone or in combination of two or more. By using a polyglycerin-modified silicone that dissolves in component (b), the polyglycerin-modified silicone can be incorporated into water and function as a dispersant for hydrophobic titanium oxide microparticles in water. Note that "soluble in component (b)" refers to a transparent to translucent state without a boundary when component (c) is mixed with component (b) at a concentration of 20% by mass and then allowed to stand at 25°C for 1 hour. Alternatively, "insoluble" refers to a state where the mixture becomes cloudy or separates into two layers. Furthermore, "transparent to translucent" refers to a total light transmittance of 50% or greater when the mixture is filled into a 1 cm thick cell and measured according to the method described in JIS K7361-1:1997. Note that polyglycerin-modified silicones that do not dissolve in component (b) do not qualify as component (c) of the present invention.

[0021] In terms of chemical structure, polyglycerin-modified silicones may be block-modified or graft-modified with polyglycerin, with the silicone main chain being the polyglycerin. From the viewpoint of maintaining uniform dispersibility of component (a) in the cosmetic, a branched chain is preferred. The silicone main chain may also have a branched chain such as a silicone chain. Specific examples include polyglyceryl-3 disiloxane dimethicone (INCI). From the viewpoint of water resistance, component (c) is preferably one that dissolves at 25°C when mixed in BG at a concentration of 20% by mass, and is insoluble at 25°C when mixed in water at a concentration of 20% by mass. The polyglycerin-modified silicone of the present invention may be co-modified with hydrophilic groups other than polyglycerin groups, but at least 50% by mass of the hydrophilic groups are polyglycerin groups. From the viewpoint of water resistance, silicones modified only with polyglycerin groups are preferred.

[0022] Furthermore, the polyglycerin-modified silicone used in the present invention preferably has an HLB (Hydrophile-Lipophile Balance) value of 3 or more and less than 17, more preferably 5 or more and less than 15, and even more preferably 8 or more and less than 12. A value of 3 or more further improves dispersibility, and a value less than 17 further improves water resistance. The HLB is calculated by "(sum of formula weights of hydrophilic group moieties / total molecular weight) x 20".

[0023] The content of component (c) in the aqueous dispersion is 1.0 to 20% by mass, preferably 3 to 15% by mass, more preferably 4 to 10% by mass, and even more preferably 5 to 8% by mass. If the content is less than 1.0% by mass, the stability of the dispersion may be impaired. If the content exceeds 20% by mass, the component (c) may be further oriented to the component (a) or the component (c) that is not oriented to the component (a) may be easily peeled off. As a result, the viscosity of the dispersion may increase or the dispersibility in an aqueous medium may be affected.

[0024] Furthermore, the mass ratio (c) / (b) of the content of component (c) to the content of component (b) is preferably 0.2 to 0.9. In particular, from the viewpoints of dispersibility and water resistance, a ratio of 0.3 to 0.8 is more preferable, and a ratio of 0.4 to 0.5 is even more preferable. By setting this ratio to 0.2 or more, component (c) is more likely to be oriented toward component (a), an increase in viscosity is suppressed, and stability is further improved. On the other hand, by setting it to 0.9 or less, component (c) is dispersed by the dispersion medium, is more likely to be oriented toward component (a), an increase in viscosity is suppressed, and stability is further improved.

[0025] [Component (d)] Component (d) of the present invention is water. Examples of water that can be used include ion-exchanged water, distilled water, deionized water, purified water as defined in the Japanese Pharmacopoeia, hot spring water, and deep sea water.

[0026] The content of component (d) in the aqueous dispersion is 8 to 82% by mass, preferably 18 to 72% by mass, and more preferably 28 to 40% by mass. Although a stable dispersion can be obtained at a content of less than 8% by mass, it is difficult to achieve the objective of lowering the viscosity by incorporating component (d). On the other hand, if the content exceeds 82% by mass, problems with stability over time may occur.

[0027] The total content of components (a), (b), (c), and (d) relative to the entire aqueous dispersion of the present invention is preferably 90 to 100% by mass, more preferably 95 to 100% by mass, and even more preferably 99 to 100% by mass. By making the total content of components (a), (b), (c), and (d) 90% by mass or more, the influence of components other than components (a), (b), (c), and (d) is reduced, and a dispersion with better stability and usability can be produced.

[0028] An antifoaming agent may be added to the aqueous dispersion for the purpose of improving handleability during preparation, filling, etc. Examples of antifoaming agents include salts such as simethicone (INCI), dimethicone (INCI), sodium chloride (labeled name (INCI: Sodium Chloride)), polyether-modified silicone, etc. Furthermore, oil-based agents such as dimethicone may be used as a pre-emulsified emulsion type, and compound-based agents such as simethicone may be used as a self-emulsifying type pre-mixed with a silicone surfactant, etc. Among these, simethicone and sodium chloride are particularly preferred in terms of foam-breaking and foam-suppressing properties, and simethicone is most preferred in terms of affinity with cosmetic ingredients. When an antifoaming agent is incorporated, the amount thereof is preferably 0.0001 to 1% by mass of the total aqueous dispersion, more preferably 0.0025 to 0.6% by mass, and even more preferably 0.005 to 0.01% by mass.

[0029] [Aqueous Dispersion] The aqueous dispersion of the present invention can be easily blended into an aqueous medium. The "dispersion" in "aqueous dispersion" refers to a composition containing 8 to 82 mass % of water, in which temporary settling is observed in the dispersibility test described in the Examples below, but the dispersion becomes uniform upon continued stirring.

[0030] [Form of aqueous dispersion] The dispersion of the present invention is preferably liquid and has a viscosity of 10 mPa·s or more but less than 200,000 mPa·s, more preferably 10 mPa·s or more but less than 10,000 mPa·s, and even more preferably 10 mPa·s or more but less than 5,000 mPa·s. By making the viscosity 10 mPa·s or more, the stability of the dispersion is further improved. On the other hand, from the viewpoint of handleability, a viscosity of 200,000 mPa·s or less is preferable. The viscosity is measured at 25°C using a B-type viscometer (TVB-10 model, manufactured by Toki Sangyo Co., Ltd.) according to the method described in JIS K 7117-1:1999.

[0031] [Method for producing aqueous dispersion] When preparing the aqueous dispersion of the present invention, the method and apparatus therefor are not particularly limited, and can be carried out by a known method. For example, any stirrer, grinder, mixer, medium stirrer, planetary mixer, ribbon blender, disperser, homomixer, jet mill, roll mill, bead mill, high-pressure disperser, etc. can be used. In particular, from the viewpoint of mixing efficiency, it is preferable to carry out dispersion using a bead mill or high-pressure disperser.

[0032] [Cosmetics] The aqueous dispersion of the present invention can be used for various purposes, but is particularly applicable as a raw material for all cosmetics that are applied externally to the skin or hair.

[0033] When the aqueous dispersion of the present invention is blended in a cosmetic, the amount is preferably 0.5 to 60% by mass, more preferably 1.0 to 50% by mass, and even more preferably 5.0 to 40% by mass, based on the total amount of the cosmetic. By blending it in an amount of 0.5% by mass or more, a sufficient UV protection effect can be expected, and by blending it in an amount of 60% by mass or less, the feeling during use can be further improved.

[0034] Cosmetics containing the aqueous dispersion of the present invention may be in any form, for example, a water-in-oil emulsion cosmetic, an oil-in-water emulsion cosmetic, an aqueous cosmetic, or a multiple emulsion such as a W / O / W type or an O / W / O type. In particular, when used as a dispersion of an oil-in-water emulsion cosmetic, it is easy to apply, and a stable cosmetic having excellent transparency, usability, and water resistance can be obtained.

[0035] The cosmetic of the present invention can be in a variety of forms, including liquid, emulsion, cream, solid, paste, gel, powder, pressed, multilayered, mousse, spray, stick, and pencil form. Multilayered cosmetic preparations are those that separate into two or more layers upon standing. They are filled into a container containing a stainless steel ball or the like and are used after shaking. Because the dispersion of the present invention has good dispersibility, it is easy to redisperse even in this formulation. These are called shaking types, and because they are easily stabilized, they provide a cosmetic preparation with an excellent feel in use, but require the effort of shaking. Because the cosmetic of the present invention is preferred for its stability, it can be used without separating into multiple layers. Sprayed cosmetic preparations are sprayed into dispenser containers, aerosol containers, etc., and used by spraying from a nozzle. The cosmetic filled into the dispenser container is sprayed in a mist from the dispenser nozzle. The aerosol container is filled with the cosmetic and a propellant. The propellant is not particularly limited, and examples thereof include various liquefied petroleum gases (LPG), dimethyl ether, nitrogen gas, carbon dioxide gas, etc. These may be used alone or in appropriate combinations of two or more. The aqueous dispersion of the present invention has high dispersibility and can be used in such formulations.

[0036] The aqueous dispersion of the present invention can be applied to various cosmetics, but is particularly preferably applied to cosmetics applied to the skin, such as skin care cosmetics, makeup cosmetics, antiperspirant cosmetics, and UV protection cosmetics, and to cosmetics applied to the hair, such as hair cosmetics. Examples of skin care cosmetics include lotions, emulsions, creams, cleansers, packs, oil liquids, massage products, beauty serums, beauty oils, detergents, deodorants, hand creams, lip balms, and wrinkle concealers. Examples of makeup cosmetics include makeup bases, concealers, face powders, powder foundations, eye color, eye shadow, mascara, eyeliner, eyebrow pencils, and lipsticks. Examples of antiperspirant cosmetics include roll-on, cream, solution, and stick-type antiperspirant cosmetics. Examples of UV protection cosmetics include sunscreen oils, sunscreen emulsions, and sunscreen creams. Examples of hair cosmetics include shampoos, rinses, treatments, and setting agents. Among these, UV protection cosmetics are preferred.

[0037] The cosmetic preparation of the present invention may contain various components commonly used in cosmetic preparations to the extent that the effects of the present invention are not impaired. For example, the cosmetic preparation may contain (1) an oil, (2) an aqueous component other than components (b) and (d), (3) a surfactant other than component (c), (4) a powder other than component (a), (5) a composition comprising a crosslinked organopolysiloxane and an oil that is liquid at room temperature, (6) a film-forming agent, and (7) other additives. These may be used alone or in appropriate combinations of two or more. Components contained in the dispersion described above may also be incorporated. However, even if components (a) to (d) of the present invention are incorporated without the dispersion of the present invention, the significant effects intended by the present invention cannot be achieved. The amounts of components (a) to (d) other than the dispersion are not particularly limited as long as they do not impair the effects of the present invention. When the cosmetic preparation is incorporated separately from the dispersion, the amount of component (a), excluding the amount in the dispersion, is preferably 0.0 to 20% by mass, more preferably 0.0 to 10% by mass, of the cosmetic preparation. The amount of component (b) in the cosmetic is preferably 0.0 to 70% by mass, more preferably 0.0 to 50% by mass, and even more preferably 0.0 to 25% by mass. The amount of component (c) in the cosmetic is preferably 0.0 to 3.0% by mass, and more preferably 0.0 to 1.0% by mass. The dispersion of the present invention is highly stable, and when blended into a cosmetic, it does not inhibit the performance of the emulsifier or dispersant in the cosmetic, allowing the amount of component (c) other than the dispersion to be reduced.
