Description

Technical Field

[0001] The present invention relates to a dispersion containing fine particle inorganic powder, and a cosmetic containing this dispersion.

Background Art

[0002] Generally, in sunscreen cosmetics, fine particle inorganic powders such as titanium oxide and zinc oxide are widely used in order to improve transparency and enhance the ultraviolet ray shielding effect. However, due to the large surface area of this inorganic powder, the interaction between particles becomes strong, and as a result, it has the property of being easily aggregated.

[0003] These fine particle inorganic powders are made into a dispersion for the convenience of blending into cosmetics, transparency, and improvement of the ultraviolet ray shielding effect. Various techniques for dispersing such highly aggregative powders have been studied so far (Patent Document 1). Among them, polyglycerol-modified silicone is known to have high dispersibility with respect to the above powders (Patent Document 2). Patent Document 3 examines an oil-in-water type cosmetic in which fine particle inorganic powder is dispersed in an oil phase. However, no study has been made on the dispersion of highly aggregative powders in an aqueous medium by polyglycerol-modified silicone.

[0004] On the other hand, Patent Document 4 describes a surface-treated powder in which titanium oxide or zinc oxide is coated with silica and has excellent dispersibility in water. However, when this treated powder is blended into a cosmetic, there are problems in terms of transparency, spread during application, and usability.

[0005] Also, Patent Document 5 examines a dispersion containing a nonionic surfactant, but sufficient dispersibility has not been obtained. From these facts, there has been a demand for a dispersion that further improves dispersibility and gives a good usability when blended into a cosmetic.

[0010] According to the present invention, it is possible to provide a dispersion that exhibits excellent dispersibility in aqueous media and high dispersion stability. When used as a dispersion in cosmetics, it is easy to add and can provide cosmetics with excellent transparency, feel, and water resistance. In particular, it is possible to provide a highly stable dispersion even for titanium dioxide fine particles, which are difficult to disperse. [Modes for carrying out the invention]

[0011] The present invention will be described in detail below. In this invention, ingredient names may be described using cosmetic names or International Nomenclature of Cosmetic Ingredient (INCI). If the cosmetic name and INCI correspond, the English description may be omitted.

[0012] [(a) component] Component (a) of the present invention is a hydrophobized fine inorganic powder. The fine inorganic powder can be any raw material that can be normally incorporated into cosmetics, which is a powder used as an ultraviolet scattering agent that has an ultraviolet shielding effect, and can be used alone or in combination of two or more. Among these, a metal oxide selected from one or more of titanium dioxide, zinc oxide, and cerium oxide is preferred. This metal oxide may be a composite powder of two or more of titanium dioxide, zinc oxide, and cerium oxide, or a composite powder with other powders.

[0013] (a) The number-average primary particle diameter of component (a), determined by image analysis of transmission electron microscope images, is 10 to 200 nm, preferably 150 nm or less. If the particle diameter is larger than 200 nm, the UV protection function decreases, and white residue may remain. If the particle diameter is less than 10 nm, the drying sensation may become strong, resulting in a poor user experience. The average primary particle diameter of component (a) of the present invention can be measured by transmission electron microscope images. If the powder is not spherical, the average value of the shortest diameter of the particles is used as the average primary particle diameter. Examples of shapes for fine inorganic powders include spindle-shaped, needle-shaped, straw-bundle-shaped, strip-shaped, nearly spherical, and rod-shaped.

[0014] The fine particle inorganic powder may be surface-treated with silica, hydrous silica, alumina, aluminum hydroxide, etc. before the hydrophobization treatment for the purpose of reducing the cohesiveness or suppressing the activity of the powder. When there is concern about inhibiting the swelling of the water-soluble polymer used in combination during the formulation of cosmetics or reducing the water resistance, it is preferably a composite powder that has not been surface-treated with alumina or aluminum hydroxide. When there is concern about reducing the water resistance, it is preferably a composite powder that has not been surface-treated with silica or hydrous silica.

[0015] The hydrophobization treatment agent for the above fine particle inorganic powder is not particularly limited as long as it is a known treatment agent generally used in cosmetics. For example, silanes or silylating agents such as caprylyl silane (manufactured by Shin-Etsu Chemical Co., Ltd.: AES-3083), silicone oils such as dimethyl silicone (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-96AK series), methyl hydrogen type polysiloxane (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-99P, KF-9901, etc.), silicone-branched silicone treatment agents (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-9908, KF-9909, etc.), waxes, paraffins, organic fluorine compounds such as perfluoroalkyl phosphates, surfactants, amino acids such as N-acylglutamic acid, metal soaps such as aluminum stearate and magnesium myristate, etc. can be mentioned. In particular, a component containing one or more selected from stearic acid, isostearic acid, and triethoxycaprylyl silane will result in good treatment and is preferable in terms of dispersibility with the component (c). The hydrophobization treatment method is not particularly limited and can be treated by known methods. For example, wet treatment methods, dry treatment methods, vapor phase methods, etc. can be mentioned.

[0016] Commercially available products can also be used for these surface-treated fine particle inorganic powders. For example, in the case of fine particle titanium oxide, it is commercially available under trade names such as MT-01, 02, 050OTS, 100Z, 100TV, 100SAS, 150EX, 200ST, 500SAM, 505SAS, 700Z, 700BS (manufactured by Teika), ST-455, 455WS, 457ECS, 457SA, 495M, 455FA (manufactured by Titanium Industry), STR-100A-LP, 100C-LP, 100W-LP, 100C-LF, 40-LP (manufactured by Sakai Chemical Industry), etc. In the case of fine particle zinc oxide, it is commercially available under trade names such as MZ-150, 200, 300, 306X, 500HP, 505T, 506X, MZY-203S, 210M3S, TMZ-HA1, MZX-5080TS (manufactured by Teika), FZO-50 (manufactured by Ishihara Sangyo), etc.

[0017] The content of component (a) is 10 to 70% by mass of the dispersion, and preferably 20 to 70% by mass from the viewpoint of usability. In particular, when (d) water is blended, it is preferably 10 to 55% by mass, and more preferably 30 to 50% by mass. If it is less than 10% by mass, a sufficient ultraviolet shielding effect cannot be obtained, and if it is blended in excess of 70% by mass, the spreadability during use may deteriorate, or the stability of the dispersion over time may decrease and the viscosity may increase.

[0018] [Component (b)] Component (b) of the present invention is an aqueous component having one or more alcoholic hydroxyl groups, that is, a component that dissolves in water at 25°C, and can be used alone or in combination of two or more. Specifically, examples include lower alcohols having preferably 2 to 5 carbon atoms, such as ethanol (indication name (INCI): Alcohol) and isopropanol (indication name (INCI): Isopropyl Alcohol) and sugar alcohols such as sorbitol (INCI), maltose (INCI), xylitol (INCI), glucose (INCI), glyceryl glucoside (INCI), sodium chondroitin sulfate (indication name (INCI): Sodium Chondroitin Sulfate)), methyl gluceth-10 (INCI), methyl gluceth-20 (INCI), hyaluronic acid, phosphatidylglycerol, and phosphatidylinositol. Other examples include polyhydric alcohols such as BG (Indication name (INCI: Butylene Glycol)), PG (Indication name (INCI: Propylene Glycol)), DPG (Indication name (INCI: Dipropylene Glycol)), pentylene glycol (INCI), 1,10-decanediol (INCI), octanediol (INCI), 1,2-hexanediol (INCI), erythritol (INCI), glycerin (INCI), diglycerin (INCI), and polyethylene glycol. Of these, polyhydric alcohols such as BG (butylene glycol), DPG (dipropylene glycol), and glycerin are preferred due to their solubility in water in any proportion and their versatility as cosmetic ingredients. Glycols having two alcoholic hydroxyl groups in the molecule are particularly preferred.

[0019] (b) The content of component (b) is 1.0 to 30% by mass of the dispersion, preferably 1.5 to 25% by mass, more preferably 5 to 25% by mass, and even more preferably 5.0 to 15% by mass. Below 1.0% by mass, the stability of the dispersion deteriorates, and above 30% by mass, the cosmetic becomes sticky, and component (b) inhibits the orientation of component (c) to component (a), which may increase viscosity or impair dispersibility in aqueous media. By incorporating component (b), component (c), described later, can be uniformly oriented on the surface of component (a).

[0020] [(c) component] Component (c) of this invention is a polyglycerin-modified silicone that dissolves in component (b). "Dissolves in component (b)" means that when component (c) is mixed with component (b) at a concentration of 20% by mass and then left to stand at 25°C for 1 hour, a transparent to translucent state without boundaries is considered "dissolved," while cloudiness or separation into two layers is considered "not dissolved." Transparency is determined to be transparent to translucent if the total light transmittance measured in accordance with the method described in JIS K7361-1:1997 when filled into a 1 cm thick cell is 50% or higher.

[0021] Polyglycerin-modified silicones may be chemically structured by using polyglycerin and modifying the main silicone chain in a block-type or branch-type manner. (a) From the viewpoint of maintaining the uniform dispersion of component in cosmetics, it is more preferable to use a branch-type. The silicone main chain may have branched chains such as silicone chains. Specifically, polyglyceryl-3 disiloxane dimethicone (INCI) is an example. An example of a commercially available product is KF-6100 manufactured by Shin-Etsu Chemical Co., Ltd. Furthermore, even if a silicone is polyglycerin-modified, if it does not dissolve in component (b), for example, polyglyceryl-3 polydimethylsiloxyethyl dimethicone (INCI name: Polyglyceryl-3 Polydimethylsiloxyethyl dimethicone) and lauryl polyglyceryl-3 polydimethylsiloxyethyl dimethicone (INCI name: Lauryl Polyglyceryl-3 Polydimethylsiloxyethyl Dimethicone) do not fall under component (c) of the present invention.

[0022] The content of component (c) is 1.0 to 20% by mass of the dispersion, preferably 3 to 20% by mass, more preferably 5 to 15% by mass, and even more preferably 7 to 12% by mass. Below 1.0% by mass, the stability of the dispersion deteriorates, and above 20% by mass, component (c) may become oriented towards component (a), or component (c) that is oriented towards component (a) may become more easily detached by component (c) that is not oriented towards component (a), which may increase the viscosity of the dispersion or affect its dispersibility in aqueous media.

[0023] Furthermore, the ratio of the amount of component (c) to the amount of component (b), expressed as (c) / (b), is preferably 0.35 to 1.0. In particular, 0.4 to 0.9 is preferred in terms of dispersibility and water resistance, and 0.7 to 0.9 is even more preferred. If this ratio is less than 0.35, component (b) will inhibit component (c) from orienting toward component (a), which may result in increased viscosity or impaired stability. If it exceeds 1.0, component (c) will not be sufficiently dispersed in the dispersion medium and will have difficulty orienting toward component (a), which may result in increased viscosity of the dispersion or affect its stability.

[0024] [(d) component] The present invention may also contain water, which is component (d). As water, ion-exchanged water, distilled water, deionized water, purified water as defined in the Japanese Pharmacopoeia, hot spring water, deep-sea water, etc. can be used. According to the present invention, even when component (d) is added, a low-viscosity and stable dispersion can be obtained.

[0025] (d) When component is included, the amount is preferably 8 to 82% by mass of the dispersion, more preferably 28 to 72% by mass, and even more preferably 32 to 59% by mass. A stable dispersion can be obtained even at less than 8% by mass, but it is difficult to achieve the objective of reducing viscosity by including component (d). On the other hand, if it exceeds 82% by mass, problems may arise with stability over time.

[0026] Furthermore, when component (d) is included, an antifoaming agent may be added to improve handling during preparation and filling. Examples of antifoaming agents include salts such as simethicone (INCI), dimethicone (INCI), and sodium chloride (indicated name (INCI: Sodium Chloride)), and polyether-modified silicones. Oil-based agents such as dimethicone may be used in the form of a pre-emulsified emulsion type, and compound-based agents such as simethicone may be used in the form of a self-emulsifying type that has been pre-mixed with a silicone surfactant, etc. Among these, simethicone and sodium chloride are particularly preferred in terms of antifoaming and foam suppression properties, and simethicone is most preferred in terms of affinity with cosmetic ingredients. The amount of antifoaming agent is preferably 0.0001 to 1% by mass of the total dispersion, more preferably 0.0025 to 0.6% by mass, and even more preferably 0.005 to 0.01% by mass.

[0027] (d) If component is not included, the present invention becomes a slurry-like dispersion, which is highly versatile for transportation and formulation as a dispersion at high concentrations. On the other hand, by including component (d), a low-viscosity dispersion is obtained, making it easier to handle.

[0028] In particular, when component (d) is included, the absolute viscosity of the dispersion at 25°C is preferably 1 to less than 6,000 mPa·s, more preferably 1 to less than 1,000 mPa·s, and even more preferably 1 to less than 500 mPa·s. The absolute viscosity is measured using a B-type viscometer according to the method described in JIS K 7117-1:1999.

[0029] [Dispersion] The dispersion of the present invention is easy to blend into aqueous media, and in the dispersibility test of the examples described later, although temporary sedimentation is observed, it disperses uniformly when stirring is continued, exhibiting the effect of an aqueous dispersion.

[0030] [Method for manufacturing dispersions] When preparing the dispersion of the present invention, there are no particular limitations on the method or apparatus, and it can be carried out by known methods. For example, any agitator, grinder, mixer, media agitator, rotational agitator, disperser, etc., such as a Henschel mixer, ball mill, kneader, planetary mixer, ribbon blender, disperser, jet mill, roll mill, bead mill, etc., can be used. In particular, from the viewpoint of mixing efficiency, dispersion using a bead mill is preferred.

[0031] [Cosmetics] The dispersion of the present invention can be used for various purposes, but is particularly applicable as a raw material for all cosmetic products applied topically to the skin and hair.

[0032] This invention dispersion The cosmetic composition containing this ingredient may take any form, such as a water-in-oil emulsion, a polyhydric alcohol-in-oil emulsion, an oil-in-water emulsion, an aqueous cosmetic, a W / O / W type, an O / W / O type multi-emulsion, etc. In particular, when used as a dispersion of an oil-in-water emulsion, it is easy to add and a stable cosmetic composition with excellent transparency, feel, and water resistance can be obtained.

[0033] The cosmetic composition of the present invention can be expressed in various forms, including liquid, emulsion, cream, solid, paste, gel, powder, pressed, multilayer, mousse, spray, stick, and pencil. A multilayer composition is a cosmetic composition that separates into two or more layers when left standing, and is filled into a container with stainless steel balls or the like, and used after shaking. Because the dispersion of the present invention has good dispersibility, it is easy to redisperse even in such a dosage form. This is called a shaking type, and because it is easily stabilized, it is a cosmetic composition with a good feel to use, but it requires the effort of shaking. Because the cosmetic composition of the present invention has good stability, it can be used without separating into multiple layers. A spray type is a spray-type cosmetic composition that is filled into a dispenser container, aerosol container, etc., and used by spraying it from a nozzle. The cosmetic composition filled into a dispenser container is sprayed in a mist from the dispenser nozzle. The cosmetic composition and propellant are filled into an aerosol container together. The propellant is not particularly limited, and for example, various liquefied petroleum gases (LPG), dimethyl ether, nitrogen gas, carbon dioxide, etc. can be used. These can be used individually or in appropriate combinations of two or more. Since the dispersion of the present invention has high dispersibility, it can be used in such dosage forms.

[0034] The present invention is applicable to various types of cosmetics, but is particularly preferred for cosmetics applied externally to the skin, such as skincare cosmetics, makeup cosmetics, antiperspirant cosmetics, and UV protection cosmetics, and for cosmetics applied externally to the hair, such as hair cosmetics. Examples of skincare cosmetics include lotions, emulsions, creams, cleansers, masks, oil liquids, massage products, serums, beauty oils, cleansing agents, deodorants, hand creams, lip balms, and wrinkle concealers. Examples of makeup cosmetics include makeup bases, concealers, face powders, powder foundations, eye colors, eyeshadows, mascaras, eyeliners, eyebrow products, and lipsticks. Examples of antiperspirant cosmetics include roll-on type, cream type, solution type, and stick type antiperspirant cosmetics. Examples of UV protection cosmetics include sunscreen oils, sunscreen emulsions, and sunscreen creams. Examples of hair cosmetics include shampoos, conditioners, treatments, and styling agents. Among these, UV protection cosmetics are the most preferred.

[0035] The cosmetic composition of the present invention may contain various components commonly used in ordinary cosmetics, to the extent that they do not impair the effects of the present invention. For example, it 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 consisting of a cross-linked organopolysiloxane and an oil that is liquid at room temperature, (6) a film-forming agent, and (7) other additives. These can be used individually or in appropriate combinations of two or more.
