Disclosure of Invention
Problems to be solved by the invention
However, in the conventional cosmetic compositions containing a powder, the powder is precipitated, aggregated and solidified, and there is a problem that so-called "caking" is likely to occur. Since the powder is strongly agglomerated, it is sometimes difficult to disperse (redisperse) the powder even if it is shaken during use. When such a cosmetic is filled in a spray container and sprayed, the aggregate of the powder may block the spray mechanism and cause a spray failure. The problem of the above-mentioned caking tends to occur particularly easily in a cosmetic material having a large ethanol content or a cosmetic material having a low viscosity.
Therefore, an object of the present invention is to provide a cosmetic composition which contains powder but is inhibited from caking.
Means for solving the problems
The present inventors have conducted intensive studies to achieve the above object and, as a result, have found that the following cosmetic composition containing component (a): powder of starch octenylsuccinate metal salt and/or powder of talc, component (B): an oily component having an IOB value of 0 to 0.45, component (C): ethanol, and component (D): water, wherein the content of the component (A) is 0.01-15.0% by mass, the content of the component (C) is 25.0-80.0% by mass, and the mass ratio of the component (B) to the component (A) [ component (B)/component (A) ] is 0.003-3.0. The present invention has been completed based on these technical ideas.
That is, the present invention provides a cosmetic composition comprising the following component (a), the following component (B), the following component (C), and the following component (D), wherein the content of the component (a) is 0.01 to 15.0% by mass, the content of the component (C) is 25.0 to 80.0% by mass, and the mass ratio of the component (B) to the component (a) [ component (B)/component (a) ] is 0.003 to 3.0.
Component (A): powder of starch octenylsuccinate metal salt and/or powder of talc
Component (B): an oily component having an IOB value of 0 to 0.45
Component (C): ethanol
Component (D): water (W)
The cosmetic composition is preferably a pickering emulsion.
The cosmetic composition contains no nonionic surfactant and/or anionic surfactant, and the content of the nonionic surfactant and/or anionic surfactant in the cosmetic composition is preferably 0.1% by mass or less.
The component (B) is preferably an oily component, which is 1 or more selected from the group consisting of silicone oil, hydrocarbon oil, ester oil, and vegetable oil.
The cosmetic composition may further contain the following component (E).
Component (E): polyglyceryl-10decaisostearate
The cosmetic composition may further contain the following component (F).
Component (F): isopropyl methyl phenol
The content ratio of the component (B) in the cosmetic composition is preferably 1.0% by mass or less.
ADVANTAGEOUS EFFECTS OF INVENTION
The cosmetic composition of the present invention is a powder-containing cosmetic composition, but is inhibited from caking. Therefore, for example, even if the powder is in a settled state, the powder is easily redispersed by shaking, and the spray mechanism is not easily clogged when the powder is filled in a spray container and sprayed. Further, the cosmetic composition of the present invention is excellent in appearance because the powder is easily redispersed by shaking.
Detailed Description
The cosmetic composition of the present invention comprises at least a powder of a starch octenylsuccinate metal salt and/or a powder of talc, an oily component having an IOB value of 0 to 0.45, ethanol and water. In the present specification, a powder of the metal salt of starch octenylsuccinate and/or a powder of talc may be referred to as "component (a)", an oily component having an IOB value of 0 to 0.45 as "component (B)", ethanol as "component (C)", and water as "component (D)".
That is, the cosmetic composition of the present invention contains at least the component (a), the component (B), the component (C), and the component (D). The cosmetic composition of the present invention may contain components other than the above components (a) to (D). The cosmetic composition of the present invention may contain only one or two or more of each component, for example, the component (a), the component (B), the component (C), the component (D), and other components.
The cosmetic composition of the present invention is preferably a pickering emulsion, and more preferably a pickering emulsion having an aqueous phase containing the component (D) and an oil phase (oil droplets) containing the component (B) dispersed in the aqueous phase. The pickering emulsion has a structure in which the component (a) is present at the interface between the aqueous phase and the oil phase. When the cosmetic composition of the present invention is a pickering emulsion, an emulsion composition can be formed without substantially containing a nonionic surfactant and an anionic surfactant. Therefore, the cosmetic composition of the present invention can form an emulsified composition containing no nonionic surfactant and/or anionic surfactant or containing a nonionic surfactant and/or anionic surfactant in a proportion of 0.1% by mass or less.
[ component (A) ]
The component (A) is a powder selected from the group consisting of starch octenyl succinate metal salt and talc. That is, the component (a) is one or both of an octenyl succinate starch ester metal salt and talc. The component (a) is a component generally used in a cosmetic composition, and is used for the purpose of imparting a dry feeling to the skin or hair after use, adsorbing sebum, adjusting the skin tone after application, and the like. The cosmetic composition of the present invention is characterized in that the component (a) is used in combination with the components (B) to (D) to form a pickering emulsion, whereby the caking of the component (a) can be suppressed and the redispersibility can be improved even when the powder is precipitated. The component (A) may be used alone or in combination of two or more.
Examples of the metal salts of octenyl succinic starch ester include aluminum salts, calcium salts, barium salts, and iron salts of octenyl succinic starch ester. Among them, aluminum salt (aluminum starch octenyl succinate) is preferable. The aluminum starch octenylsuccinate described above is sometimes referred to as aluminum starch octenylsuccinate or aluminum corn starch octenylsuccinate. Further, the above-mentioned ALUMINUM STARCH OCTENYLSUCCINATE may be referred to as "ALUMINUM STARCH octenylsuccinamate" under the name INCI (international nomenclature for cosmetic raw materials).
In the cosmetic composition of the present invention, the component (a) is a powder. The starch octenylsuccinate metal salt is heated to a relatively high temperature (for example, 60 ℃ or higher) to cause hydrophilization/gelation (so-called "gelatinization") and is not in a powder state, and is sometimes used as a thickener. The cosmetic composition of the present invention is characterized by being contained in a powder state when the starch octenyl succinate metal salt is blended. Therefore, in the manufacturing process of the cosmetic composition of the present invention, the metal salt of starch octenyl succinate is preferably used at less than 60 ℃ (more preferably less than 55 ℃).
The talc is not particularly limited, and talc generally used in cosmetic compositions can be used. The TALC is referred to as TALC under the INCI name.
The oil absorption of the talc is not particularly limited, but is preferably 18ml/100g to 50ml/100 g. The average particle diameter D50 of the talc is not particularly limited, but is preferably 0.5 to 25.0. mu.m, more preferably 1.0 to 20.0. mu.m.
In the present specification, the oil absorption of talc is a value measured according to the measurement method described in JIS K5101. In the present specification, the average particle diameter D50 of talc is a value measured by a laser diffraction method.
Commercially available products may be used as the component (A). As a commercially available product of starch octenylsuccinate metal salt, there may be mentioned, for example, the trade name "DRY-FLO PURE", the trade name "DRY-FLO PC" (manufactured by Nouroyn Co., Ltd.), the trade name "オクティエ" (manufactured by Nikkiso Co., Ltd.), and the like. Commercially available products of Talc include those sold under the trade name "Talc MS" (manufactured by Nippon Talc Co., Ltd.).
The content of the component (a) in the cosmetic composition of the present invention is 0.01 to 15.0% by mass, preferably 0.1 to 10.0% by mass, and more preferably 0.4 to 5.0% by mass, based on 100% by mass of the cosmetic composition of the present invention. When the content ratio is less than 0.01% by mass, the caking inhibition effect of the present invention is not clearly exhibited, since no strong caking occurs first. When the content is 0.4% by mass or more, the frictional resistance against the skin by the component (a) can be reduced, and the effect of imparting a dry feeling to the skin after the cosmetic composition is used is particularly improved. If the content exceeds 15.0 mass%, the amount of the component (a) becomes too large, and dispersion failure may occur. In addition, the remaining component (a) which does not form the pickering emulsion may coagulate and settle, and sometimes cause lumps which are difficult to redisperse. When the content is 10.0% by mass or less, the effect of suppressing so-called "whitening" in which the skin looks whitish after application due to the component (a) is particularly improved, and the feeling of use is particularly improved without excessively increasing the feeling of touch by the powder. The content ratio of the component (a) is the total of the content ratios of all the components (a) in the cosmetic composition of the present invention.
[ component (B) ]
The component (B) is an oily component having an IOB value of 0 to 0.45. The component (B) is a low-polarity or non-polar oily component having a low IOB value, and is hardly dissolved in the component (C) in the presence of the component (C), and exerts an effect of forming a pickering emulsion from the component (A) and the component (D). Further, since the component (a) becomes a constituent component of the emulsion by forming the pickering emulsion, it is possible to suppress the occurrence of strong agglomeration due to the closest packing by only the particles settling. Therefore, it can be easily redispersed by shaking after settling. The component (B) may be used alone or in combination of two or more.
The IOB value of the component (B) is 0 to 0.45, preferably 0 to 0.35, and more preferably 0 to 0.15. When the IOB value is within the above range, the component (a) and the component (D) do not completely dissolve in the component (C) in the presence of the component (C), and thus the effect of forming a pickering emulsion is exerted. The IOB value is a value of each oily component contained in the cosmetic composition of the present invention, and is a value of each oily component when two or more components (B) are contained. The IOB (inorganic organic Balance) value is a value obtained by dividing an inorganic value (inorganic) by an organic value (organic). The IOB value of each component (B) can be determined, for example, based on the japanese good birth, "organic concept map-base and application-", the three publications, and the 1984 release (pages 11 to 17).
Examples of the component (B) include silicone oils, hydrocarbon oils, ester oils, vegetable oils, and the like having an IOB value of 0 to 0.45.
Examples of the silicone oil include dimethyl silicone oils such as dimethylpolysiloxane (polydimethylsiloxane), high-polymer dimethylpolysiloxane, and decamethylcyclopentasiloxane; and methylphenylsilicone oil such as methylphenylpolysiloxane.
Examples of the hydrocarbon oil include isoparaffin, light liquid isoparaffin, squalane, synthetic squalane, vegetable squalane (including sucrose squalane and olive squalane), liquid isoparaffin, liquid paraffin, hydrogenated polyisobutene, isododecane, mineral oil, and the like.
Examples of the ester oil include isopropyl myristate, isopropyl palmitate, myristyl myristate, cetyl palmitate, 2-ethylhexyl palmitate, octyldodecyl myristate, isopropyl isostearate, cetyl 2-ethylhexanoate, glyceryl tri-2-ethylhexanoate, glyceryl tri (octanoate/decanoate), isononyl isononanoate, diisopropyl adipate, pentaerythritol tetraoctanoate, diisostearyl malate, dipentaerythritol hexahydrostearate, and the like.
Examples of the vegetable oil include macadamia nut oil, eucalyptus oil, Shea butter (Shea butter), jojoba oil, castor oil, olive oil, palm oil, sunflower oil, argan oil, coconut oil, avocado oil, safflower oil, palm kernel oil, macadamia nut oil, cocoa butter, almond oil, sunflower oil, rose fruit oil, kiwi seed oil, apricot kernel oil, sesame oil, soybean oil, hazelnut oil, meadowfoam oil, peppermint oil, carrot oil, lavender oil, camellia oil, and hydrogenated products thereof (e.g., hydrogenated castor oil, hydrogenated jojoba oil, hydrogenated palm oil, hydrogenated avocado oil, hydrogenated soybean oil, etc.).
Component (B) is preferably liquid at 25 ℃. The viscosity η of the component (B) measured at 25 ℃ with a Brookfield type rotational viscometer is preferably 30000 mPas or less (for example, 0.1 to 30000 mPas), more preferably 1.0 to 10000 mPas.
As the component (B), among them, liquid paraffin, squalane (including sucrose squalane, olive squalane), jojoba oil, hexadecyl 2-ethylhexanoate, isononyl isononanoate, methylphenylpolysiloxane, glyceryl 2-ethylhexanoate, methylpolysiloxane, castor oil are preferable.
The content of the component (B) in the cosmetic composition of the present invention is not particularly limited, and is preferably 5.0% by mass or less, more preferably 4.0% by mass or less, further preferably 1.0% by mass or less, further preferably 0.5% by mass or less, and particularly preferably 0.3% by mass or less with respect to 100% by mass of the cosmetic composition of the present invention. When the content ratio is 5.0% by mass or less, all the component (B) is easily incorporated into the pickering emulsion, and the appearance can be further improved. When the content ratio exceeds 5.0% by mass, the amount of the component (B) is too large, and the component (B) not contained in the pickering emulsion exists in the form of oil droplets, and thus spots may occur in the cosmetic composition. Further, when the content ratio is 1.0 mass% or less, it is preferable to further suppress the component (B) not contained in the pickering emulsion from becoming oil droplets, floating on the surface layer, or adhering to the wall surface of the container, and to improve the appearance in particular. The content of the component (B) is not particularly limited, and is, for example, 0.002 mass% or more, preferably 0.01 mass% or more, and more preferably 0.03 mass% or more. The content ratio of the component (B) is the total of the content ratios of all the components (B) in the cosmetic composition of the present invention.
In the cosmetic composition of the present invention, the mass ratio of the component (B) to the component (a) [ component (B)/component (a) ] is 0.003 to 3.0, preferably 0.01 to 3.0, more preferably 0.02 to 0.18, and further preferably 0.05 to 0.17. If the mass ratio is less than 0.003, the amount of the component (B) as an oil component becomes insufficient relative to the amount of the component (a), and the component (a) not contained in the pickering emulsion is present in a large amount, so that blocking occurs and redispersibility is lowered. When the mass ratio exceeds 3.0, the amount of the component (B) becomes excessive relative to the amount of the component (a), and spots may occur in the cosmetic composition. Further, the component (B) not contained in the pickering emulsion is in the form of oil droplets, floats on the surface layer, or adheres to the wall surface of the container, and impairs the aesthetic properties. There is a possibility that an oil phase is formed in the cosmetic composition, oil floating occurs, and the beauty is impaired.
[ component (C) ]
The component (C) is ethanol. By using the component (C), the specific gravity of the aqueous phase in the Pickering emulsion is reduced, and the emulsion particles are easily settled. This improves the appearance of the cosmetic composition of the present invention. In addition, the cosmetic composition of the present invention can be provided with quick-drying and refreshing feeling in use. In addition, in the production process of the cosmetic composition of the present invention, the component (C) also functions as a dispersion medium for dispersing the hydrophobic component (a).
The content of the component (C) in the cosmetic composition of the present invention is 25.0 to 80.0% by mass, preferably 30.0 to 70.0% by mass, and more preferably 40.0 to 60.0% by mass, based on 100% by mass of the cosmetic composition of the present invention. When the content is 25.0% by mass or more, part of the emulsion particles in the cosmetic composition is likely to settle, and the cosmetic appearance is improved. If the content exceeds 80.0 mass%, a irritating sensation and a dry sensation tend to occur.
[ component (D): water ]
Component (D) is water, but is not particularly limited, and purified water is preferred. The content of the component (D) in the cosmetic composition of the present invention is preferably 5.0 to 74.98% by mass, more preferably 15.0 to 70.0% by mass, even more preferably 20.0 to 65.0% by mass, and particularly preferably 30.0 to 55.0% by mass, based on 100% by mass of the cosmetic composition of the present invention.
[ component (E) ]
The cosmetic composition of the present invention may further comprise polyglyceryl-10 decaisostearate. Polyglycerol-10 Decaisostearate is known under the INCI name as polyglycyl-10 Decaisostearate. In the present specification, polyglycerol-10 decaisostearate may be referred to as "component (E)". Component (E) is an ester compound synthesized from a decamer of glycerol and 10 equivalents of isostearic acid, having a hydrophilic moiety derived from 2 hydroxyl groups and 10 ester groups and a lipophilic moiety derived from isostearyl group per 1 molecule. Presumably: the component (E) is attached to the component (a) through a hydrophilic portion, and the hydrophobicity of the component (a) is increased through a lipophilic portion. As a result, since the release of the component (a) from the emulsion particles is reduced, it is presumed that the cloudiness of the aqueous phase in the cosmetic composition can be further suppressed, and the cosmetic composition is more excellent in appearance. The component (E) may be used alone or in combination of two or more.
The content of the component (E) in the cosmetic composition of the present invention is not particularly limited, and is preferably 0.0005 to 1.0% by mass, more preferably 0.001 to 0.5% by mass, and still more preferably 0.001 to 0.3% by mass, based on 100% by mass of the cosmetic composition of the present invention. When the content ratio is 0.0005 mass% or more, the effect of suppressing turbidity in the aqueous phase is further improved. When the content ratio is 1.0% by mass or less, the aggregation-inhibiting effect of the component (a) is further improved.
The mass ratio of the component (E) to the component (a) [ component (E)/component (a) ] in the oil-in-water emulsion composition of the present invention is preferably 0.001 to 0.3, more preferably 0.005 to 0.25, and further preferably 0.005 to 0.15. When the mass ratio is 0.001 or more, the effect of suppressing the turbidity of the aqueous phase is further improved. When the content ratio is 0.3 or less, the aggregation-inhibiting effect of the component (a) is further improved.
[ component (F) ]
The cosmetic composition of the present invention may further comprise isopropyl methylphenol. In the present specification, isopropyl methylphenol may be referred to as "component (F)". Component (F) is a bactericidal component that exerts a bactericidal action when the cosmetic composition of the present invention is applied to the skin. In addition, when a hydrocarbon oil is contained as the component (B) in a system containing the component (F) and the component (C) at a high concentration, it is presumed that the hydrocarbon oil forms an oil film after being applied to the skin, and the loss of the component (F) due to moisture such as sweat can be suppressed, and the component (F) is likely to remain on the skin for a long time. Therefore, the bactericidal action of the component (F) remaining on the skin is sustained for a long period of time, and the deodorizing effect is excellent in the persistence when used as a body fragrance agent.
The content of the component (F) in the cosmetic composition of the present invention is preferably 0.01 to 3.0% by mass, more preferably 0.05 to 2.0% by mass, based on 100% by mass of the cosmetic composition of the present invention. When the content is 0.01% by mass or more, the cosmetic composition has more excellent bactericidal activity. When the content ratio is 3.0% by mass or less, it is preferable in terms of less skin irritation.
The cosmetic composition of the present invention may further comprise polyacrylate crosspolymer-6. POLYACRYLATE CROSSPOLYMER-6 is known under the INCI name POLYACRYLATE CROSSPOLYMER-6. It is presumed that when a certain structure is formed in the composition by compounding the polyacrylate crosslinked polymer-6 and the amount of the component (C) to be mixed is small, the pickering emulsion particles do not settle or float on the surface layer even when compounded at a high concentration, and become a state of floating in the composition, and the blocking can be further suppressed. And, the peculiar beauty that emulsion particles float in the composition is exhibited. In addition, when a colorant such as a pigment is added, the pickering emulsion particles can be colored, and a cosmetic composition having more excellent aesthetic properties can be obtained.
Examples of commercially available products of the polyacrylate crosslinked polymer-6 include a product name "SEPIMAXZEN" (manufactured by SEPPIC CORPORATION).
The content of the polyacrylate crosslinked polymer-6 in the cosmetic composition of the present invention is not particularly limited, but is preferably 0.05 to 3.0% by mass, more preferably 0.1 to 1.5% by mass, based on 100% by mass of the cosmetic composition of the present invention. When the content ratio is 0.05% by mass or more, the pickering emulsion particles are more likely to float in the composition, and the appearance is further improved. When the content is 3.0% by mass or less, the feeling of use is further improved.
[ other ingredients ]
The cosmetic composition of the present invention may contain components (other components) other than the above components (a) to (F). The other components are not particularly limited, and examples thereof include components generally used in cosmetics and quasi drugs. Specifically, examples thereof include: a lower alcohol other than the component (C); surfactants other than the component (E), such as cationic surfactants and amphoteric surfactants; a polyol; glycyrrhizic acid and its salt as anti-inflammatory agent; cooling agents such as menthol; phosphoric acid and its salts, citric acid and its salts, lactic acid and its salts, sodium hydroxide, triethanolamine and other pH regulators; a fragrance; an ultraviolet absorber; an antioxidant; a preservative; a chelating agent; a pigment; a pigment; vitamins; amino acids; an astringent; a whitening agent; an animal or plant extract; a neutralizing agent; a bactericide other than the component (F); an antiperspirant; a deodorant; an acid; alkali, and the like.
The antiperspirant is, for example, an agent for suppressing the generation of sweat by astringing the skin. Examples of the antiperspirant include aluminum chloride, aluminum potassium sulfate, aluminum acetate, chlorohydroxyaluminum, allantoin chlorohydroxyaluminum, zinc p-phenolsulfonate, and the like.
The bactericide is, for example, a drug for inhibiting the growth of skin-resident bacteria that produce a substance causing body odor. Examples of the bactericide other than the component (F) include benzalkonium chloride, benzethonium chloride, chlorhexidine hydrochloride, phenol, triclocarban, chlorhexidine gluconate, triclosan, triclocarban, piroctone olamine, zinc pyrithione, salicylic acid, sorbic acid, lysozyme chloride, and the like.
Examples of the cooling agent include menthol, menthyl ether, menthyl lactate, camphor, and irine.
The cosmetic composition of the present invention preferably does not contain a nonionic surfactant and an anionic surfactant, or the content ratio of the nonionic surfactant and/or the anionic surfactant is 0.1% by mass or less, more preferably 0.01% by mass or less. The cosmetic composition of the present invention can form an emulsion and disperse powder without using a surfactant, and thus does not need to use a surfactant for dispersing powder. When the content is 0.1% by mass or less, irritation and stickiness to the skin due to the nonionic surfactant and the anionic surfactant can be prevented. In addition, since the formation of the pickering emulsion using the component (a) is not inhibited, the caking of the component (a) can be further suppressed.
Examples of the nonionic surfactant include sorbitan fatty acid esters, glycerin fatty acid esters, alkylene oxide adducts thereof, polyoxyalkylene alkyl ethers, polyoxyalkylene fatty acid esters, polyoxyalkylene alkylphenols, polyoxyethylene sorbitol fatty acid esters, polyoxyethylene alkylphenyl formaldehyde condensates, polyoxyethylene sterols and derivatives thereof, polyoxyethylene lanolin and derivatives thereof, polyoxyethylene beeswax derivatives, sugar esters, polyoxyethylene hydrogenated castor oil, and polyoxyethylene castor oil.
Examples of the anionic surfactant include higher fatty acid soaps, alkyl sulfate ester salts, alkyl phosphates, polyoxyethylene alkyl ether sulfates, polyoxyethylene alkylphenyl ether sulfates, alkyl ether phosphate esters, alkyl ether carboxylates, acyl methyl taurates, N-acyl-N-methyl- β -alanates, N-acyl glycinates, N-acyl glutamates, polyoxyethylene alkyl carboxylates, alkylphenyl ether sulfonates, alkylsulfosuccinic acid and its salts, N-acyl sarcosines and its salts, and polyoxyethylene oil coconut fatty acid monoethanolamide sulfates.
The cosmetic composition of the present invention preferably contains no thickener or a thickener content of 1.0% by mass or less, more preferably 0.5% by mass or less. In the case of compounding a powder in a cosmetic composition, the sedimentation of the powder can be generally prevented by increasing the viscosity by compounding a thickener. However, the cosmetic composition of the present invention is excellent in redispersibility without depending on a thickener, and thus there is no need to add a thickener to increase the viscosity of the cosmetic composition. In addition, the thickening agent can prevent the stickiness after coating. The components corresponding to the component (A), the component (B) and the polyacrylate crosslinked polymer-6 are not included in the thickener.
Examples of the thickener include water-soluble polymers. Examples of the water-soluble polymer include carboxyvinyl polymers, acrylic acid/alkyl methacrylate copolymers, hydroxymethylcellulose, hydroxypropylmethylcellulose, xanthan gum, and the like.
The cosmetic composition of the present invention is not particularly limited, and can be produced by a known or customary method. For example, the following methods can be mentioned: the components are mixed and homogenized by a method of stirring using a known stirring apparatus such as a dispersion mixer or a paddle mixer. In particular, from the viewpoint that more component (a) can be blended and that large-particle-size pickering emulsion particles that are visually observable can be more easily formed, the following method is preferred: the component (a), the component (B), and, if necessary, other oil-soluble components are blended, first a nonaqueous mixed solution substantially not containing water is prepared, and then the component (C) and the component (D), and further the other components such as the component (E) and the component (F) are added to the nonaqueous mixed solution, followed by emulsification.
The cosmetic composition of the present invention is obtained by blending a powder of an octenyl succinate starch ester metal salt and/or a powder of talc [ component (a) ] in a specific ratio in water [ component (D) ] and blending an oil component [ component (B) ] having an IOB value of 0 to 0.45 so that the mass ratio of the components falls within a specific range, thereby forming a pickering emulsion in which the component (a) is oriented around the component (B). Thus, since the component (a) precipitates in the state of emulsion particles (fluffy state), unlike the case of precipitation only from particles, it is not packed densely and hardly agglomerated. Therefore, when the particles are settled, the component (a) can be easily redispersed by shaking at the time of use. Further, the agglomerated powder does not remain on the bottom of the container and detracts from the beauty, and therefore the cosmetic composition of the present invention is also excellent in beauty.
If the ratio of the component (B) to the component (a) is too high, the remaining component (B) becomes oil droplets, floats on the liquid surface, or adheres to the wall surface, and the appearance is degraded. If the ratio of the component (B) to the component (a) is too low, the component (a) does not form a pickering emulsion, and agglomeration may occur.
Further, by blending ethanol [ component (C) ] at a specific ratio, the specific gravity of the aqueous phase in the pickering emulsion can be reduced, and thereby the emulsion particles can be settled, and the appearance can be improved. In addition, quick drying properties can be imparted.
Thus, the cosmetic composition of the present invention is excellent in powder blocking inhibition/redispersibility and also excellent in appearance.
The formulation of the cosmetic composition of the present invention is not particularly limited, and examples thereof include emulsion (deposition), spray, sheet, and roll. The cosmetic composition of the present invention has good redispersibility and is less likely to clog a spray mechanism during use, and therefore, is preferably used as a spray formulation. When the cosmetic composition of the present invention is in the form of a spray, it is filled in a container (spray container) capable of being discharged in the form of a mist and used as a spray product. The spray product includes a container capable of discharging the content in the form of mist and the cosmetic composition of the present invention filled in the container. Examples of the container include a container having a pump dispenser or a trigger dispenser.
Examples of the cosmetic composition of the present invention include a body odor inhibitor (body fragrance agent), a refreshing cosmetic, a toner, a hair cosmetic, a shaving cosmetic, a wiping cosmetic (sheet cosmetic), and the like. The cosmetic composition of the present invention can be used for a cosmetic composition containing a powder and highly blended with ethanol, and is therefore preferably a body fragrance agent (an odor inhibitor used for the purpose of suppressing body odor), a refreshing cosmetic, or a sheet cosmetic.
Examples of the application part when applying the cosmetic composition of the present invention to the body include, for example, armpits, arms, feet, soles, necks, chests, trunks, buttocks, faces, and hair.
The sheet cosmetic pack contains a sheet base material and the cosmetic composition of the present invention impregnated in the sheet base material. The sheet cosmetic may contain the sheet base and other components than the cosmetic composition of the present invention impregnated in the sheet base.
The cosmetic composition of the present invention can uniformly disperse the ingredient (B) by forming a pickering emulsion. Thus, in the sheet cosmetic, the sheet base material can be uniformly impregnated with the cosmetic composition of the present invention. Further, by blending the component (a) and the component (B), a feeling (smooth feeling) with low friction and no powdery feeling (dry feeling or stuck feeling by powder) can be imparted to the skin after the sheet cosmetic is used. By blending the component (C) at a specific ratio, the component (a) which has high hydrophobicity and is not normally blended as powder in an aqueous medium can be dispersed in the component (D). In addition, quick drying properties can be imparted. In addition, the sheet cosmetic can be used for wiping the skin. Thus, the cosmetic composition of the present invention can be applied to the skin in a small amount and uniformly, and can be applied while wiping off sweat and sebum on the skin, so that the skin after use is less sticky.
The sheet base is a sheet-like support that can be impregnated with the cosmetic composition of the present invention.

The basis weight of the sheet base is not particularly limited, but is preferably 20g/m2～100g/m2More preferably 25g/m2～80g/m2. When the basis weight is within the above range, the sheet base material does not curl when rubbed on the skin, and the feeling of use is excellent. In addition, the amount of the cosmetic composition impregnated per unit area of the sheet cosmetic increases. This makes it possible to obtain a sufficient effect even when the skin is used over a wide range, and is preferable because the usability of the cosmetic is further improved when the cosmetic is used as a sheet cosmetic for the body.
The sheet base may be produced by a known or conventional production method depending on the type of woven fabric, nonwoven fabric or the like. Further, commercially available products may be used as the sheet base.

The number of the cosmetic sheets stored in 1 container is not particularly limited, but is preferably 2 or more, more preferably 5 or more, more preferably 10 or more, and still more preferably 20 or more. According to this configuration, there are advantages that portability is excellent regardless of location when moving, and multiple takeouts and uses are possible. The upper limit of the number of cosmetic sheets contained in 1 container is preferably 50 sheets or less because of excellent portability.
Among the above sheet cosmetic products, the sheet cosmetic is preferably folded into two, three, four, or the like and stored in a packaging container.

The container is preferably capable of suppressing volatilization of the cosmetic composition of the present invention. The material of the container is not particularly limited, and examples thereof include resins such as polyethylene terephthalate (PET), Polyethylene (PE), and polypropylene (PP); metals such as aluminum, and the like. As the container, a packaging container (particularly, a packaging bag) made of a material in which a metal (particularly, aluminum) layer and a resin layer are laminated (for example, laminated or vapor-deposited) is preferable because the container is lightweight and has an excellent volatilization prevention effect.
Examples
The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples. The compounding amounts shown in the tables are the amounts of the respective components mixed (i.e., the amounts of the effective components mixed in the respective raw materials, so-called pure components), and are expressed as "% by mass" unless otherwise specified.
Examples A1 to A45 and comparative examples A1 to A7
Cosmetic compositions of examples A1 to A45 and comparative examples A1 to A7 were prepared by a conventional method using the components (A) to (D), etc.) described in tables 1 to 5. In regard to the IOB value of the oily component, liquid paraffin was 0, squalane was 0, jojoba oil was 0.07, hexadecyl 2-ethylhexanoate was 0.13, isononyl isononanoate was 0.2, methylphenylpolysiloxane was 0.28, glycerol 2-ethylhexanoate was 0.35, methylpolysiloxane was 0.4, castor oil was 0.43, and diisopropyl adipate was 0.55.
(evaluation)
The respective cosmetic compositions obtained in examples A1 to A45 and comparative examples A1 to A7 were evaluated as follows. The evaluation results are shown in tables 1 to 5. In the table, "-" indicates that no evaluation was performed.
(1) Sedimentation state of emulsion particles
About 40ml of each of the cosmetic compositions obtained in examples a1 to a45 and comparative examples a1 to a7 was filled in a screw tube (transparent, 50ml capacity), and left to stand at normal temperature for 10 minutes, and then the cosmetic compositions were visually observed to determine the sedimentation state of emulsion particles according to the following evaluation criteria. The results are set forth in the table.
[ sedimentation of emulsion particles ]
O (good): the emulsion particles settle.
X (bad): at least a part of the emulsion particles float on the surface layer without settling, or adhere to the wall surface of the screw pipe, and the appearance is poor.
(2) Redispersibility
About 40ml of each of the cosmetic compositions obtained in examples a1 to a45 and comparative examples a1 to a7 was filled in a screw tube (transparent, 50ml in capacity), left to stand at 5 ℃ for 24 hours, and then the screw tube was inverted upside down and restored (i.e., inverted and restored to an upright state) 3 times slowly, and then the screw tube was inverted, and the presence or absence of the remaining powder sedimentation layer on the bottom surface of the screw tube and the dispersion state of the cosmetic composition were visually confirmed, and the redispersibility of the powder was evaluated according to the following evaluation criteria. The results are set forth in the table.
[ redispersibility ]
O (good): the bottom surface has no powder sedimentation layer, and the powder is uniformly dispersed.
X (bad): a powder sedimented layer remains on the bottom surface, or the powder is not uniformly dispersed and aggregates are present.
[ Table 5]
(Table 5)
As shown in tables 1 to 5, the cosmetic composition of the present invention formed a pickering emulsion, and was excellent in redispersibility and appearance, and inhibited from caking. On the other hand, when the component (B) was not blended (comparative example a1) and when the mass ratio [ component (B)/component (a) ] was small (comparative example a2), pickering emulsion was not formed or insufficiently formed, so that redispersibility was poor and blocking occurred. In addition, when the content of the component (C) is small (comparative example a3), the specific gravity of the aqueous phase is high, and some emulsion particles are present on the surface layer, resulting in poor appearance. In addition, when a substance having a high IOB value was used as the oily component (comparative example a4), the oily component dissolved in the aqueous phase, no pickering emulsion was formed, and the redispersibility was poor. In addition, when silicic anhydride was used as the powder (comparative example a5), a pickering emulsion could not be formed. Therefore, blocking occurs and redispersibility is poor. When crosslinked polystyrene was used as the powder (comparative example a6), the powder was aggregated and the redispersibility was poor. When N ∈ -lauroyl-L-lysine was used as the powder (comparative example a7), the powder coagulated and floated on the surface layer, and the appearance and redispersibility were poor.
(3) Presence or absence of oil droplets
About 40ml of each of the cosmetic compositions obtained in examples A1 to A45 and comparative examples A1 to A7 was filled in a screw tube (transparent, 50ml capacity), and the cosmetic compositions were visually observed after standing at 50 ℃ for 7 days. As a result, in examples a1 to a12 and a16 to a45, no oil droplets were present, and the appearance was evaluated to be particularly excellent. In examples a13 to a15, although a slight oil phase was observed in the top layer of the cosmetic composition, there was no problem in practical use.
(4) Dry and comfortable feeling
Further, each of the cosmetic compositions obtained in examples A1, A2, A4 to A12, and A19 to A42 was filled in a pump dispenser, and about 0.15ml was spray-applied to the outside of one forearm and fused with the hand. Then, the skin after application was evaluated for dry feeling (feeling of reduced friction with the palm due to powder present on the skin). The above evaluation was carried out under conditions of constant temperature and constant humidity at 25 ℃ and a humidity of 50% RH. As a result, all the examples evaluated were evaluated to feel particularly dry and cool.
(5) Whitening of the skin
Each of the cosmetic compositions obtained in examples A1 to A12 and A16 to A33 was filled in a pump dispenser and spray-coated on the outside of one forearm to about 0.15 ml. The fusion operation was not performed after the spray coating. Then, the skin after application was evaluated for the presence or absence of the occurrence of whitening (a phenomenon in which the applied portion appeared to be whitish). As a result, in examples A1 to A26 and A29 to A32, no whitening was observed in the coated portion. On the other hand, in examples a27, a28, a slight whitening was observed in the coated portion, and in example a29, a clear whitening was observed in the coated portion. However, the whitening in examples a27 to a29 did not occur when the fusing operation was performed after the application.
Examples B1 to B13
The cosmetic compositions of examples B1 to B13 were prepared by a conventional method using the components (A) to (D), etc.) described in tables 6 and 7. In addition, regarding the IOB value of the oily component, the triglyceride 2-ethylhexanoate was 0.36.
(evaluation)
The cosmetic compositions obtained in examples B1 to B13 were evaluated for the "sedimentation state of emulsion particles" and the "(2) redispersibility". The evaluation results are set forth in tables 6 and 7.
[ watch 6] (watch 6)
[ watch 7] (watch 7)
(6) Presence or absence of white turbidity
About 40ml of each of the cosmetic compositions obtained in examples B1 to B16 was filled in a screw tube (transparent, 50ml capacity), and after standing at room temperature for 30 minutes, the cosmetic compositions were visually observed to determine the presence or absence of white turbidity. As a result, in examples B1 to B13, the upper layer was evaluated as transparent or clear. On the other hand, in examples B14 to B16, the upper portion was evaluated as white turbidity.
(7) Oil float
About 40ml of each of the cosmetic compositions obtained in examples B1 to B16 was filled in a screw tube (transparent, 50ml capacity), and after standing at room temperature for 30 minutes, the cosmetic compositions were visually observed, and oil floating was evaluated according to the following evaluation criteria. As a result, in all the examples evaluated, it was evaluated that the oil did not float.
As shown in tables 6 and 7, the cosmetic compositions of the present invention formed pickering emulsions, were excellent in redispersibility and aesthetics, and suppressed in caking (examples B1 to B16). Further, when the component (E) was blended, no oil floating occurred and the white turbidity was excellent (examples B1 to B13). In the case where the component (E) was not compounded (example B14), and in the case where polyglyceryl monolaurate or polyglyceryl monostearate was used without using the component (E) (examples B15 and B16), oil floating did not occur, but the degree of white turbidity was slightly poor.
Reference examples C1 to C8 and comparative examples C1 to C2
Cosmetic compositions of reference examples C1 to C8 and comparative examples C1 to C2 were prepared by a conventional method using the components (A) to (D), etc.) described in Table 8. The IOB value of the oily component was 0 for the hydrogenated polyisobutene.
(evaluation)
Each of the cosmetic compositions obtained in reference examples C1 to C8 and comparative examples C1 to C2 was evaluated as follows. A part of the evaluation results are set forth in table 8.
(8) Observation of Pickering emulsion formation
Each of the cosmetic compositions obtained in reference examples C1 to C8 and comparative examples C1 to C2 was left to stand at 25 ℃ for 24 hours and then observed with an optical microscope.
As a result, it was confirmed that pickering emulsions, which were in the form of powders on the surfaces of oil droplets dispersed in an aqueous phase, were formed in the cosmetic compositions of reference examples C1 to C8. On the other hand, comparative examples C1 and C2 did not contain an oil phase and thus did not form pickering emulsions.
(9) Residual property of isopropyl methyl phenol
0.5mL of each of the cosmetic compositions obtained in reference examples C1 to C8 and comparative examples C1 to C2 was dropped on the inner side of the forearm, and the surface of the dropping part was rubbed 5 times with a cotton swab to collect initial measurement samples. Then, after 15 minutes had elapsed, the surface of the dropping part was rubbed again with a cotton swab, and a measurement sample was collected over time. Each of the collected measurement samples was dissolved in 5mL of ethanol by immersion, and the concentration of isopropylmethylphenol in each of the ethanol was measured by High Performance Liquid Chromatography (HPLC). The ratio of "the isopropyl methylphenol concentration of the measurement sample after the lapse of time" to "the isopropyl methylphenol concentration of the initial measurement sample" was defined as "the isopropyl methylphenol remaining property", and was determined according to the following criteria. Note that significant differences were determined by Wilcoxon test.
[ criterion for determining survivability ]
O (good): the isopropyl methylphenol survivability was significantly higher compared to comparative example C2.
X (bad): it was not confirmed that the isopropyl methylphenol residue was significantly higher than that in comparative example C2.
As shown in Table 8, the cosmetic compositions of the present invention formed pickering emulsions (reference examples C1 to C8). The cosmetic composition of the present invention containing the component (F) was evaluated as having isopropyl methylphenol as a bactericide remained on the skin for a long time (reference examples C1 to C8). On the other hand, the compositions without the component (B) (comparative examples C1 to C2) did not form Pickering emulsions, and the isopropyl methylphenol residue was inferior to the compositions of the reference examples.
(10) Emulsion stability
Each of the cosmetic compositions obtained in reference examples C1 to C8 was charged into a screw tube having a capacity of 50mL, and left to stand at 25 ℃ for 24 hours, and then the emulsified state in each cosmetic composition was visually observed.
As a result, no separation of the oil phase was observed in any of the cosmetic compositions of reference examples C1 to C8, and good emulsion stability was observed. When the oil phase was separated, an oil layer was observed in the upper layer of the cosmetic composition.
After the above evaluation (10), the screw tube was gently shaken to fly the powder settled on the bottom of the screw tube, and the amount of the floating free powder was confirmed. As a result, almost no free powder was observed in the cosmetic compositions of reference examples C1 to C8, or the amount of free powder was such that the other side of the screw tube could be seen through the composition. When the amount of free powder is large during oscillation, clouding occurs to the extent that the other side of the screw tube is not visible, and the aesthetic quality may be deteriorated.
Reference examples D1 to D10
Cosmetic compositions of reference examples D1 to D10 were prepared by a conventional method using the components (a) to (D), etc.) described in table 9. The IOB value of the oily component is 0 for light isoparaffins.
(evaluation)
Each of the cosmetic compositions obtained in reference examples D1 to D10 was evaluated as follows. The evaluation results are shown in Table 9.
(11) Dispersibility of emulsion particles (floatability)
About 40ml of each of the cosmetic compositions obtained in reference examples D1 to D10 was charged into a screw tube (transparent, 50ml capacity), and left to stand at 25 ℃ and 40 ℃ for 24 hours, and then the compositions were visually observed to determine the sedimentation state of the emulsion particles according to the following evaluation criteria. As a result, in all the reference examples evaluated, the emulsion particles floated in the composition under either of the conditions of 25 ℃ and 40 ℃, and there were almost no substances floating on the surface layer and substances settled on the bottom.
Thus, the cosmetic composition of the present invention containing polyacrylate crosspolymer-6 was evaluated as excellent in aesthetic appearance by blending ethanol at a high concentration and in a state where emulsion particles were suspended in the composition (reference examples D1 to D10).
After the evaluation in the above evaluation (11), oil droplets (emulsion particles) having a size that can be visually observed were present in the cosmetic compositions of reference examples D1 to D7. In addition, in reference examples D1 to D7, separation of the oil phase was not confirmed, and good emulsion stability was confirmed. When the oil phase was separated, an oil layer was observed in the upper layer of the cosmetic composition.
Examples E1 to E24 and comparative examples E1 to E2
Cosmetic compositions of examples E1 to E24 and comparative examples E1 to E2 were prepared by a conventional method using the components (A) to (D)) described in tables 10 and 11. In addition to this, the present invention is,the cosmetic composition was impregnated at a basis weight of 40g/m in an amount of 290 parts by mass based on 100 parts by mass of the nonwoven fabric2In the spun-laced nonwoven fabrics of (1) examples E1 to E24 and comparative examples E1 to E2, each cosmetic sheet (sheet size: 14 cm. times.20 cm, rectangular shape) was prepared. The IOB value of the oily component was 0 for mineral oil, 0.13 for 2-ethylhexyl palmitate, 0.18 for isopropyl myristate, 0.09 for octyl dodecyl myristate, 0.3 for decamethylcyclopentasiloxane, and in the range of 0 to 0.45 for each vegetable oil.
(evaluation)
The cosmetic compositions and the cosmetic tablets obtained in examples E1 to E24 and comparative examples E1 to E2 were evaluated as follows. The evaluation results are set forth in tables 10 and 11. In the table, "-" indicates that no evaluation was performed.
(12) Smooth feeling
Using 1 piece of each of the cosmetics obtained in examples E1 to E24 and comparative examples E1 to E2, the inside of one forearm was wiped back and forth 3 times, and the wiped portion was evaluated for smoothness immediately after wiping and evaluated according to the following criteria. The above evaluation was carried out under conditions of constant temperature and constant humidity at 25 ℃ and a humidity of 50% RH.
[ judgment Standard for smoothness ]
O (good): the skin after use feels less friction, and the skin after use feels no powdery feeling (seizure by powder or dry feeling by powder) and feels moderate moisture.
X (bad): the skin after use did not feel less friction or the skin after use felt a powdery feel (seizure by powder or dry feel by powder).
(13) No stickiness
In the evaluation of the above smooth feeling, the non-stickiness when the sheet cosmetic was wiped off was evaluated, and the evaluation was performed according to the following criteria.
[ criterion for determining non-tackiness ]
O (good): the skin after use did not feel sticky (oily feeling).
X (bad): the skin after use was strongly sticky (oily feeling).
(14) Whitening of the skin
Whitening was visually evaluated on the wiped portion 10 minutes after wiping of the sheet cosmetic in the evaluation of the above slippery feel. The above evaluation was carried out under conditions of constant temperature and constant humidity at 25 ℃ and a humidity of 50% RH. The judgment was made according to the following evaluation criteria.
[ criterion for whitening ]
O (excellent): the coated portion was not whitened.
X (bad): the coated portion as a whole generates whitening.
(15) Oil float
The cosmetic compositions obtained in examples E1 to E24 and comparative examples E1 to E2 were charged into a glass container, left to stand at 25 ℃ for 10 minutes, and then visually observed to determine the formation of an oil phase according to the following evaluation criteria. The results are set forth in the table.
[ oil flotation ]
O (good): the upper layer had no oil droplets.
X (bad): oil droplets were present in the upper layer.
As shown in tables 10 and 11, according to the sheet cosmetics using the cosmetic composition of the present invention, smooth feeling can be imparted. Further, the grease-free property was excellent, and whitening and oil floating were not observed. On the other hand, when the mass ratio of the component (B) to the component (a) is high (comparative examples E1 and E2), oil floatation occurs.
