Description

[Technical Field]

[0001] The present invention relates to an oil-in-water emulsion cosmetic suitable as a base cosmetic or a sunscreen cosmetic, and more particularly to an oil-in-water emulsion cosmetic that has excellent smoothness and storage stability. [Background technology]

[0002] Oil-in-water emulsion cosmetics formed by dispersing an oil in an aqueous phase provide a fresher feel when used compared to water-in-oil emulsion cosmetics formed by dispersing an aqueous phase in an oil phase, and are therefore widely used as makeup cosmetics such as foundations. Conventionally, powder components such as silica powder and silicone elastomers have been blended into such oil-in-water emulsion cosmetics to improve their performance.

[0003] For example, Patent Document 1 describes a décolleté cosmetic containing silicic anhydride, titanium mica and / or titanium dioxide-coated borosilicate glass flakes, and crosslinked methylpolysiloxane (see claim 1), and describes its formulation as an oil-in-water emulsion cosmetic (see Example 1 in paragraph 0023). This cosmetic was developed primarily to achieve visual harmony between the décolleté and face (see paragraph 0009), and describes that the preferred blend amount of silicic anhydride is 10 to 30% by mass, more preferably 15 to 25% by mass, and the preferred blend amount of crosslinked methylpolysiloxane is 0.1 to 20% by mass, more preferably 1 to 10% by mass (see paragraphs 0012 and 0014).

[0004] Patent Document 2 describes an oil-in-water emulsion cosmetic containing crosslinked methylpolysiloxane and spherical powder (see claim 1). This cosmetic was developed with the objective of making pores less noticeable with a natural finish (see paragraph 0007), and describes that the preferred blend amount of spherical powder such as silica is 0.005 to 10% by mass, more preferably 0.01 to 1% by mass (see paragraph 0011), and that the preferred blend amount of crosslinked methylpolysiloxane is 0.1 to 20% by mass, more preferably 0.1 to 20% by mass (see paragraph 0010).

[0005] Oil-in-water emulsion cosmetics containing spherical powders such as silicic anhydride (silica) have been well known for some time. However, while the greater the content of spherical powder, the smoother the feel after application, the more the powder tends to become localized during film formation, making wrinkles more noticeable and resulting in an unnatural finish. Therefore, there is a natural limit to the amount of spherical powder that can be used when the cosmetic is used as a makeup cosmetic, which places importance on the appearance of the applied surface.

[0006] Meanwhile, cosmetics containing spherical silica and a water-soluble thickener, a carboxyvinyl polymer or its salt, are also known, and for example, Patent Document 3 describes a skin topical preparation containing a dibasic acid ester, a spherical powder, and a carboxyvinyl polymer and / or its salt (see claim 1). This topical preparation was developed with the objective of suppressing the loss of aesthetic appearance caused by excessive lipid secretion (see paragraph 0005), and describes that the preferred blend amount of the spherical powder is 0.01 to 20% by mass, more preferably 0.1 to 15% by mass (see paragraph 0009), and that the preferred blend amount of the carboxyvinyl polymer and / or its salt is 0.05 to 2% by mass, more preferably 0.1 to 1% by mass (see paragraph 0010).

[0007] However, when preparing oil-in-water cosmetics containing spherical silica, the incorporation of a water-soluble thickener tends to impair the stability over time (storage stability) of the formulation, and this tendency is particularly pronounced when a large amount of spherical powder is included. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-238459 [Patent Document 2] Japanese Patent Application Laid-Open No. 2007-039371 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0009] The present invention was completed against this background, and an object of the present invention is to provide an oil-in-water emulsion cosmetic that has excellent smoothness and storage stability while retaining the characteristic fresh feel of oil-in-water cosmetics. [Means for solving the problem]

[0010] As a result of intensive research conducted by the present inventors to solve the above-mentioned problems, they discovered that when a silicone elastomer is blended into an oil-in-water emulsion cosmetic containing spherical silica powder and a specific water-soluble thickener is used, storage stability is not impaired even when a large amount of spherical silica powder is contained, and they have completed the present invention.

[0011] Thus, according to the present invention, there is provided an oil-in-water emulsion cosmetic comprising (A) water, (B) a hydrophilic surfactant, (C) silica powder, (D) a silicone elastomer, and (E) an acrylamide-based thickener. [Effects of the Invention]

[0012] The oil-in-water emulsion cosmetic of the present invention has excellent smoothness and storage stability while retaining the characteristic fresh feel of oil-in-water cosmetics. BEST MODE FOR CARRYING OUT THE INVENTION

[0013] The oil-in-water emulsion cosmetic of the present invention contains, as essential components, (A) water, (B) a hydrophilic surfactant, (C) silica powder, (D) a silicone elastomer, and (E) an acrylamide thickener. Each component will be described in detail below.

[0014] <(A) Water> The cosmetic preparation of the present invention is an oil-in-water emulsion and therefore contains water as an essential component. The water is not particularly limited as long as it is water that is commonly used in the preparation of cosmetics, and may be ion-exchanged water, distilled water, or the like. The water content is usually 30 to 60% by mass, preferably 40 to 50% by mass.

[0015] <(B) Surfactant> In the present invention, a hydrophilic surfactant is contained to stabilize the oil-in-water emulsion. The hydrophilic surfactant is not particularly limited as long as it is one that is commonly used in the technical field of oil-in-water emulsion cosmetics, and specific examples thereof include, for example, anionic surfactants such as higher fatty acid salts such as sodium stearate and potassium isostearate, acylated amino acid salts such as sodium stearoyl glutamate and sodium lauroyl glycine, alkyl ether carboxylates, and alkyl sulfates; amphoteric surfactants such as aminoacetic acid betaine-type amphoteric surfactants such as lauryl betaine, aminopropionic acid-type amphoteric surfactants such as lauramidopropyl betaine, and sulfobetaine-type amphoteric surfactants such as lauryl hydroxysultaine; Examples of surfactants include polyglycerin fatty acid esters such as polyglyceryl-10 laurate, polyglyceryl-10 myristate, and polyglyceryl-10 oleate, polyoxyethylene hydrogenated castor oils such as PEG-60 hydrogenated castor oil, polyoxyethylene fatty acid esters such as PEG-10 oleate, and polyoxyethylene fatty acid glyceryl oleate such as PEG-15 glyceryl oleate; polyoxyethylene alkyl ethers, fatty acid polyoxyethylene alkyl ethers; polyoxyethylene sorbitan fatty acid esters, polyoxyethylene polyoxypropylene copolymers, ethers of polyoxyethylene polyoxypropylene copolymers and long-chain alcohols; and nonionic surfactants such as ethers of polybutylene glycol polyglycerin copolymers and long-chain alcohols.

[0016] The HLB value of the hydrophilic surfactant is not particularly limited as long as an oil-in-water emulsion cosmetic can be obtained, but it is preferably 8 or higher, and its content is preferably 0.1 to 3 mass% of the total cosmetic. The inclusion of a hydrophilic surfactant improves the stability of the emulsion, but if the content is too high, the water resistance of the coated film will decrease.

[0017] The use of anionic surfactants such as sodium stearate and potassium isostearate as hydrophilic surfactants can improve the stability of the emulsion without reducing the water resistance of the coating film. Among these, alkali metal salts of isostearic acid (such as sodium salt and potassium salt) are particularly preferred.

[0018] <(C) Silica powder> In the present invention, silica powder is contained to provide long-lasting makeup and a smooth feel when used. The silica is preferably spherical, and its volume-average particle size is usually 3 to 20 μm, preferably 4 to 15 μm. The volume-average particle size can be measured using a laser diffraction / scattering particle size distribution analyzer (e.g., LA-950 manufactured by Horiba, Ltd.).

[0019] The silica powder is preferably porous, and its oil absorption is typically 10 to 400 mL / 100 g, preferably 20 to 200 mL / 100 g, and more preferably 30 to 100 mL / 100 g. When the oil absorption is within this range, a cosmetic product with excellent makeup durability and a smooth feel can be easily obtained. Note that the "oil absorption" in the present invention is a value measured in accordance with JIS K5101-13-2:2004 (boiled linseed oil method).

[0020] Commercially available silica powders can be used, and examples of commercially available products that can be used include SATINIER M5, SATINIER M13, SILICA MICRO BEAD P-1500, SILICA MICRO BEAD L-1500, CHIFFONSIL P-3R, SILICA PEARL 20MB, and SILICA PEARL 20LB (all manufactured by JGC Catalysts and Chemicals Co., Ltd.), and SUNSPHARE H-51, SUNSPHARE L-51, and SUNSPHARE NP-100 (all manufactured by AGC Si-Tech Co., Ltd.).

[0021] The silica powder may also be a composite powder containing other metal oxides. The metal oxides to be contained are not particularly limited, but examples include titanium oxide, zinc oxide, cerium oxide, aluminum oxide, and iron oxide. Examples of commercially available composite powders include Sunsil-Tin50 (manufactured by Sunjin Chemical Co., Ltd.), SUNVEIL S70, and HCS Reflle (all manufactured by JGC Catalysts and Chemicals), which are silicas containing titanium oxide, and the PC Ball series (manufactured by Suzuki Oil & Fat Co., Ltd.), which are silicas containing iron oxide.

[0022] The silica content is selected appropriately depending on the performance requirements of the intended cosmetic, but to obtain a sufficient smooth feeling, it is preferably 20% by mass or more, more preferably 25% by mass or more. Furthermore, if the silica content is too high, the advantage of oil-in-water cosmetics, that of a moist feeling, is reduced, the stability of the system over time is reduced, and furthermore, a whitish cast is likely to occur, so the upper limit is preferably 40% by mass. A more preferred upper limit is 35% by mass.

[0023] <(D) Silicone elastomer> The cosmetic of the present invention contains a silicone elastomer. The silicone elastomer may be any silicone elastomer commonly used as a component of cosmetics, and specific examples include, for example, (dimethicone / vinyl dimethicone) crosspolymer, (dimethicone / phenyl vinyl dimethicone) crosspolymer, (vinyl dimethicone / lauryl dimethicone) crosspolymer, dimethicone crosspolymer, polysilicone-11, and (dimethicone / (PEG-10 / 15)) crosspolymer.

[0024] The silicone elastomer can be blended in the form of a silicone elastomer dispersion, which is formed by swelling the silicone elastomer with oil and dispersing it in an oil phase to form a gel. The silicone elastomer dispersion typically contains 5 to 30% by mass of silicone elastomer and 70 to 95% by mass of oil. Preferably, the ratios are 5 to 25% by mass of silicone elastomer and 75 to 95% by mass of oil. If the silicone elastomer content in the dispersion is too low or too high, poor emulsification is likely to occur.

[0025] The oil component that forms the oil phase of the silicone elastomer dispersion is typically a silicone oil such as dimethylpolysiloxane (dimethicone), trimethicone, methyltrimethicone, methylphenylpolysiloxane (diphenyldimethicone), cetyl PEG / PPG-10 / 1 dimethicone, or cyclopentasiloxane, but is not necessarily limited to these, and any oil that can swell the crosslinked silicone elastomer may be used. Examples of such oils include cetyl ethylhexanoate, 1,3-butylene glycol diisononanoate, 1,3-butylene glycol di-2-ethylhexanoate, dipropylene glycol diisononanoate, dipropylene glycol di-2-ethylhexanoate, isononyl isononanoate, isotridecyl isononanoate, tri(caprylic / capric)glyceryl, glyceryl tri-2-ethylhexanoate (triethylhexanoin), glyceryl tricaprate, glyceryl triisostearate, and neopentyl dicaprate. Ester oils such as glycol, ethylhexyl palmitate, isostearyl neopentanoate, myristoylmethyl-β-alanine (phytosteryl / decyltetradecyl), and dipentaerythrityl tri-polyhydroxystearate; liquid oils and fats such as camellia oil, evening primrose oil, macadamia nut oil, olive oil, rapeseed oil, corn oil, sesame oil, jojoba oil, germ oil, and wheat germ oil, and oils and fats such as cocoa butter, coconut oil, palm oil, and palm kernel oil; hydrocarbon oils such as isododecane, liquid paraffin, squalene, and squalane.

[0026] Commercially available silicone elastomer dispersions can be used, and specific examples of commercially available products include KSG-15, KSG-16, and KSG-210 manufactured by Shin-Etsu Chemical Co., Ltd., DOWSIL® 9040 SILICONE ELASTOMER BLEND manufactured by Dow-Toray Industries, Inc., and Gransil DMG-6 manufactured by Grant Industries. KSG-15 is a silicone gel composed of 4 to 10 mass% of a crosslinked silicone polymer (dimethicone / vinyl dimethicone) crosspolymer and 90 to 96 mass% of a silicone oil cyclopentasiloxane. KSG-16 is a silicone gel composed of 20 to 30 mass% of a (dimethicone / vinyl dimethicone) crosspolymer and 70 to 80 mass% of dimethicone. KSG-210 is a silicone gel composed of 20 to 30 mass% of a (dimethicone / (PEG-10 / 15)) crosspolymer and 70 to 80 mass% of simethicone.

[0027] The content of the silicone elastomer is usually 0.3 to 3% by mass, preferably 0.5 to 2% by mass. When the silicone elastomer is blended as a gel dispersion swollen with an oil, the content of the gel dispersion is usually 3 to 10% by mass, preferably 4 to 8% by mass, although this is not necessarily constant depending on the content of the oil constituting the dispersion. If the content of the silicone elastomer is too low, it is likely to cause pores to be less visible, while if it is too high, it is likely to cause poor spreadability and freshness, and also to have a negative impact on the stability of the formulation.

[0028] <(E) Acrylamide-based thickener> The cosmetic of the present invention contains an acrylamide thickener to stabilize the oil-in-water emulsion. A preferred acrylamide thickener is a copolymer or crosspolymer containing 2-acrylamido-2-methylpropanesulfonic acid or its salt (hereinafter sometimes abbreviated as "AMPS") as a constituent unit. The term "2-acrylamido-2-methylpropanesulfonic acid" is synonymous with "acryloyldimethyltaurine." Specific examples of acrylamide thickeners include (ammonium acryloyldimethyltaurate / vinylpyrrolidone) copolymer, (sodium acryloyldimethyltaurate / vinylpyrrolidone) crosspolymer, (dimethylacrylamide / sodium acryloyldimethyltaurate) crosspolymer, (acrylamide / sodium acryloyldimethyltaurate) copolymer, (sodium acrylate / sodium acryloyldimethyltaurate) copolymer, and (hydroxyethyl acrylate / sodium acryloyldimethyltaurate) copolymer. Among these, (sodium acrylate / sodium acryloyldimethyltaurate) copolymer and (hydroxyethyl acrylate / sodium acryloyldimethyltaurate) copolymer are preferably used.

[0029] Commercially available examples of acrylamide thickeners include FLOCARE PSD-30, a (sodium acrylate / sodium acryloyldimethyltaurate) copolymer manufactured by SNF Corporation, SIMULGEL-EG, a dispersion containing this polymer, and SIMULGEL-NS, a dispersion containing a (hydroxyethyl acrylate / sodium acryloyldimethyltaurate) copolymer, manufactured by SEPPIC Corporation.

[0030] The content of the acrylamide thickener is 0.1 to 3 mass% of the entire cosmetic, preferably 0.2 to 2 mass%, and more preferably 0.3 to 1 mass%. If the content of the acrylamide thickener is too low, it is likely to cause phenomena such as separation of the oil and water phases, oil floating, emulsification destruction, and aggregation, resulting in poor stability, while if the content is too high, it is likely to be difficult to spread on the skin.

[0031] The oil-in-water emulsion cosmetic of the present invention may contain other ingredients that are typically incorporated into cosmetics, such as powders other than component (C), water-soluble polymers other than component (E), ultraviolet absorbers, film-forming agents, alcohols, clay minerals, resins, moisturizers, preservatives, antibacterial agents, fragrances, salts, antioxidants, pH adjusters, chelating agents, cooling agents, anti-inflammatory agents, skin-beautifying ingredients, vitamins, amino acids, nucleic acids, and inclusion compounds.

[0032] Examples of powders other than component (C) include inorganic powders such as pigment-grade titanium oxide, iron oxide, talc, and mica; organic powders such as polymer powders and metal soaps; pigment powders such as tar-based pigments; metal powders; and composite powders.

[0033] Examples of water-soluble polymers other than component (E) include carboxyvinyl polymers, alkyl-modified carboxyvinyl polymers, sodium polyacrylate, hydroxyethyl cellulose, hydroxypropyl methylcellulose, guar gum, carrageenan, xanthan gum, and pullulan. Among these, the use of at least one water-soluble thickener selected from carboxyvinyl polymers and alkyl-modified carboxyvinyl polymers together with component (E) can further improve stability while maintaining freshness and without excessively increasing the viscosity of the formulation. When such a water-soluble thickener is used in combination, its content is preferably 0.01 to 0.5% by mass, more preferably 0.02 to 0.2% by mass.

[0034] Carboxyvinyl polymer (cosmetic name: carbomer) is a cross-linked copolymer of acrylic acid, and alkyl-modified carboxyvinyl polymer is mainly a copolymer of acrylic acid and alkyl methacrylate (e.g., alkyl groups with 10 to 30 carbon atoms (C 10 ~C 30) and a copolymer of alkyl methacrylate ester having the same structure. Commercially available alkyl-modified carboxyvinyl polymers include CARBOPOL 1342, CARBOPOL 1382, CARBOPOL ETD 2020, PEMULEN TR-1, PEMULEN TR-2 (all manufactured by LUBRIZOL), AQUPEC HV-801ERK, AQUPEC HV-803ERK, AQUPEC SW-703ER, AQUPEC SW-705ER (all manufactured by Sumitomo Seika Chemicals), and commercially available carboxyvinyl polymers include CARBOPOL 940, CARBOPOL 941, CARBOPOL 980, CARBOPOL 981, CARBOPOL 934 (all manufactured by LUBRIZOL), AQUPEC HV-801EG, AQUPEC HV-805EG, AQUPEC SW-705E (all manufactured by Sumitomo Seika Chemicals).

[0035] The oil-in-water emulsion cosmetic of the present invention can be prepared according to conventional methods. For example, an oil phase containing components (C) and (D) and an aqueous phase containing components (A) and (E) are separately prepared, and the oil phase is added to the aqueous phase or the aqueous phase is added to the oil phase while stirring. In particular, a method in which a higher fatty acid is contained in the oil phase and an aqueous phase containing a base component is gradually added to the oil phase while stirring to form an oil-in-water emulsion is called the soap emulsification method or reactive emulsification method. This method is said to produce a fine emulsion with little energy because soap, which acts as an emulsifier, is produced at the interface between the oil and aqueous phases, and is therefore particularly suitable as a method for preparing the oil-in-water emulsion cosmetic of the present invention.

[0036] The oil-in-water cosmetic of the present invention may be in any form, such as a cream, gel, emulsion, or liquid (thin emulsion). This cosmetic can be used as makeup cosmetics such as foundations and primers, sunscreen cosmetics, emulsions, creams, serums, BB creams, CC creams, and other skin care cosmetics. [Example]

[0037] The present invention will be described in more detail below with reference to examples and comparative examples, but the present invention is not limited to these examples. In the following description, the blending amounts in the formulations are expressed in mass % of the total amount unless otherwise specified.

[0038] The oil-in-water cosmetic compositions in the following examples and comparative examples were evaluated as follows.

[0039] (Evaluation methods a-c) For the following evaluation items a to c, 10 evaluators applied each sample to their faces and performed a sensory evaluation on a four-level scale based on the following scoring criteria (scores).

[0040] (Evaluation items) a. Smooth feeling b. Freshness c. Less noticeable pores

[0041] (Score) 5 points: Excellent. 4 points: Excellent. 3 points: Average. 2 points: Poor. 1 point: Very poor. (Evaluation criteria) A: Average score of 4.0 or above B: Average score between 3.5 and 4.0 C: Average score between 2.5 and 3.5 D: Average score below 2.5 points

[0042] (Evaluation method: storage stability) After preparing the water-based emulsion cosmetics of the Examples and Comparative Examples, they were stored for one week in a thermostatic chamber in which the temperature changed between -10°C and 10°C in one cycle every 24 hours, and then the state of the system was visually confirmed and evaluated according to the following criteria.

[0043] (Evaluation criteria) A: Almost the same as immediately after preparation B: No significant change in condition was observed C: Significant changes in state were observed (increased viscosity, separation, etc.) D: A uniform oil-in-water emulsion composition was not obtained immediately after preparation.

[0044] Examples 1 to 4 and Comparative Examples 1 to 4 <Sunscreen lotion> The sunscreen emulsions shown in Table 1 were prepared according to the following manufacturing procedure (soap emulsification method) and evaluated using the above evaluation methods. The results are also shown in Table 1. In the following manufacturing procedure (3), a hydrophilic surfactant (Component (B)) is synthesized in situ from Component 11, isostearic acid, and Component 15, potassium hydroxide. (Manufacturing Procedure) (1) Components 1 to 11 are mixed to prepare oil phase (a). (2) Components 12 to 18 are mixed to prepare aqueous phase (b). (3) At room temperature, the oil phase (a) is mixed with the water phase (b) in small amounts to prepare a cosmetic.

[0047] As is clear from the results in Table 1, the oil-in-water emulsion cosmetics of the present invention were excellent in terms of smooth feel, moisture, pore inconspicuousness, and storage stability (Examples 1 to 4). On the other hand, cosmetics in which cellulose, polymethyl methacrylate, and (trimethylpentanediol / adipic acid / glycerin) crosspolymer were used in place of component (C) in the oil phase (Comparative Examples 1 to 3) were inferior in smooth feel, moisture, and storage stability. Furthermore, cosmetics in which xanthan gum was used in place of component (E) (Comparative Example 4) were inferior in storage stability.
