Description

Technical Field

[0001] The present invention relates to an oil-in-water type sunscreen cosmetic, and more specifically, to an oil-in-water type sunscreen cosmetic that has an ultraviolet ray protection ability (SPF value) by containing specific components, and has a fresh feeling during application, a moisturizing effect, a smooth feeling, and further a non-reattachment effect.

Background Art

[0002] Generally, protecting the skin from the harm of ultraviolet rays is one of the important issues in skin care. Therefore, various studies have been conducted to minimize the adverse effects of ultraviolet rays on the skin. For example, a method of protecting the skin from the harm of ultraviolet rays by covering the skin with a coating film containing an ultraviolet absorber or an ultraviolet scattering agent has been reported (Non-Patent Document 1).

[0003] However, in order to achieve the ultraviolet ray protection effect, it is necessary to blend a large amount of an ultraviolet absorber or an ultraviolet scattering agent. On the other hand, when a large amount of an ultraviolet absorber or an ultraviolet scattering agent is blended, the usability such as stickiness and heaviness of elongation is likely to deteriorate.

[0004] Furthermore, when aiming for a high ultraviolet ray protection effect in an oil-in-water type emulsified cosmetic, it is necessary to blend a larger amount of an ultraviolet absorber or an ultraviolet scattering agent than in a water-in-oil type emulsified cosmetic. However, when these are highly blended, it may lead to skin irritation or deterioration of the usability, causing problems (Patent Document 1).

[0005] In addition to the demand for the ultraviolet ray protection effect, consumers are seeking a fresh feeling in sunscreen cosmetics. In order to impart a high ultraviolet ray protection effect, it is necessary to blend a large amount of an ultraviolet ray protection agent, but in many cases, these are oil-soluble and may impair the fresh feeling.

[0006] As a water-in-oil sunscreen cosmetic having a fresh feeling of use, for example, Patent Documents 2 and 3 report sunscreen cosmetics with a fresh feeling of use containing an organic ultraviolet absorber. On the other hand, consumers often seek a more comfortable feeling of use, such as a moisturizing feeling and a smooth feeling, in addition to the fresh feeling of use.

[0007] In order to impart a fresh feeling of use and a smooth feeling, Patent Documents 4 and 5 report cosmetics that produce a unique crumbling feeling by blending a water-absorbing polymer, achieving both a fresh feeling of use and a smooth feeling. According to Patent Document 4, it is stated that a non-greasy and refreshing feeling of use can be obtained even when an oil-soluble ultraviolet absorber is blended. However, there is no mention of the moisturizing feeling, and although it is sufficient as a non-greasy and fresh gel-like emulsified cosmetic, it is not satisfactory as a moisturizing cosmetic. Patent Document 5 reports that a highly viscous and fresh gel can be made by blending a water-absorbing polymer, but no technology has been reported to make a non-greasy cosmetic with enhanced moisturizing feeling while maintaining the freshness.

[0008] In order to meet the needs of consumers, it is urgent to develop a sunscreen cosmetic that has a fresh feeling during application, a smooth feeling after application, and an appropriate moisturizing feeling. However, no sunscreen cosmetic that completely meets these needs has been reported in the prior art. Although it is possible to impart an ultraviolet protection effect, a fresh touch, and a smooth feeling after application, when the moisturizing feeling is enhanced, these touches are impaired and a satisfactory feeling of use cannot be obtained.

[0009] In recent years, due to the increasing frequency of mask-wearing and from the perspective of the persistence of sunscreen effects, there has been a demand for a secondary adhesion resistance effect on masks, clothing, etc. (Patent Document 6). Secondary adhesion refers to the re-adhesion of the applied sunscreen cosmetic to clothing, belongings, etc. If secondary adhesion occurs, the UV protection effect and the finish of the cosmetic film may deteriorate, and in recent years, there has also been a demand for a secondary adhesion resistance effect in sunscreen cosmetics. As technologies for enhancing the secondary adhesion resistance effect, there are disclosed technologies such as blending a large amount of components that evaporate at room temperature, such as volatile silicone oils, volatile hydrocarbon oils, volatile hydrofluoroethers, and water, to impart quick-drying properties, and technologies that combine oil-based film-forming agents such as silicone-based resins with no hard transferability (Patent Documents 7 and 8). However, Patent Documents 7 and 8 are technologies related to water-in-oil cosmetics, and if the technologies disclosed for oil-in-water cosmetics are applied, a hard film property is imparted, and the fresh feeling during use, which is the problem in the present application, is greatly impaired. Also, in terms of quality, it is difficult to blend a large amount of oil-based film-forming agents and volatile oils in water-in-oil cosmetics with less oil, and the above problems could not be solved.

[0010] Against the above background, there is a demand for the development of a sunscreen cosmetic that has a moisturizing feeling, a fresh feeling during application, a smooth feeling after application, and a secondary adhesion resistance effect.

[0016] Hereinafter, the present invention will be described in more detail. Unless otherwise noted, when the blending amount of a component is expressed as "%" below, it means mass%.

[0017] Specific examples of component (A) in the present invention include, for example, fatty acid salts derived from fatty acids having 12 to 24 carbon atoms such as sodium laurate, potassium palmitate, arginine stearate; alkyl sulfate ester salts such as sodium lauryl sulfate and potassium lauryl sulfate; alkyl ether sulfate ester salts such as triethanolamine polyoxyethylene lauryl sulfate; N-acyl sarcosine salts such as sodium lauroyl sarcosine; fatty acid amide sulfonate salts such as sodium N-stearoyl-N-methyl taurine and sodium N-myristoyl-N-methyl taurine; alkyl phosphate salts such as potassium monocetyl phosphate; polyoxyethylene alkyl ether phosphate salts such as sodium polyoxyethylene oleyl ether phosphate and sodium polyoxyethylene stearyl ether phosphate; long-chain sulfosuccinate salts such as sodium di-2-ethylhexyl sulfosuccinate; long-chain N-acyl glutamate salts such as sodium N-lauroyl glutamate, sodium N-stearoyl-L-glutamate, arginine N-stearoyl-L-glutamate, sodium N-stearoyl glutamate, and sodium N-myristoyl-L-glutamate; gemini-type anionic surfactants such as sodium dimyristoyl glutamate lysine, sodium distearoyl glutamate lysine, and sodium dilauroyl glutamate lysine. Among these, alkyl phosphate salts, long-chain N-acyl glutamate salts, and gemini-type anionic surfactants are preferred, and cetyl phosphate salts, stearoyl glutamate salts, and sodium dilauroyl glutamate lysine are more preferred.

[0018] The blending amount of component (A) in the present invention is 0.01 to 1.0% by mass based on the total amount of the oil-in-water type emulsified cosmetic. More preferably, it is 0.05 to 0.8% by mass. Outside these ranges, not only does it cause deterioration of stability and a decrease in viscosity, but also the fresh feeling during application, the smooth feeling after application, and the secondary adhesion resistance effect tend to deteriorate.

[0019] In the present invention, component (A) can be used alone or in combination of two or more.

[0020] Component (B) Acrylates Crosspolymer-2-Na is the sodium salt of a copolymer composed of one or more monomers of acrylic acid, methacrylic acid, or their simple esters, crosslinked with ethylene glycol diglycidyl ether.

[0021] As the Component (B) Acrylates Crosspolymer-2-Na (INCI name: Sodium Acrylates Crosspolymer-2), commercially available products can be used. For example, "ARON NT-Z (manufactured by Toagosei Co., Ltd.)" and "AQUAKEEP 10SH-NFC (Sumitomo Seika Chemicals Co., Ltd.)" are preferably used.

[0022] The blending amount of Component (B) Acrylates Crosspolymer-2-Na in the present invention is 1.0 to 5.0% by mass based on the total amount of the oil-in-water type emulsified cosmetic. More preferably, it is 2.0 to 4.0% by mass. Within this range, it can give a unique moist and fresh feeling that does not splash during application while having a high moisturizing feeling, and can impart a smooth feeling and an anti-redeposition effect after application.

[0023] Component (C) Hydrophobic UV absorber in the present invention is not particularly limited, and those commonly used in cosmetics can be used.

[0024] Specific examples of component (C) in the present invention include, for example, 2-ethylhexyl p-methoxycinnamate, hexyl diethylaminohydroxybenzoylbenzoate, 2,4-bis -[{4-(2-ethylhexyloxy)-2-hydroxy}-phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine, octocrylene, 2,4,6-tris[4-(2-ethylhexyloxycarbonyl)anilino]-1,3,5-triazine, glyceryl monocaprylate dipalmitate, methyl 2,5-diisopropylcinnamate, isopropyl p-methoxycinnamate·diisopropylcinnamate ester mixture, diethanolamine salt of p-methoxyhydroxycinnamic acid, amyl dimethylaminobenzoate, 2-ethylhexyl dimethylaminobenzoate, p-aminobenzoic acid, ethyl dihydroxypropyl p-aminobenzoate, glyceryl p-aminobenzoate, octyl dimethyl p-aminobenzoic acid, homomenthyl salicylate, 2-ethylhexyl salicylate, triethanolamine salicylate, dihydroxydimethoxybenzophenone, sodium dihydroxydimethoxybenzophenone disulfonate, 2,2',4,4'-tetrahydroxybenzophenone, 4,4'-dihydroxybenzophenone, 4-tert-butyl-4'-methoxydibenzoylmethane, 2-hydroxy-4-methoxybenzophenone, 2-hydroxy-4-methoxybenzophenone-5-sulfuric acid, 2,2'-dihydroxy-4-methoxybenzophenone, 2,4-dihydroxybenzophenone, 2,2'-dihydroxy-4,4'-dimethoxybenzophenone, 2-hydroxy-4-n-octyloxybenzophenone, 2-phenyl-benzimidazole-5-sulfuric acid, 4-isopropyldibenzoylmethane, 2-ethylhexyl dimethoxybenzylidene dioxoimidazolidine propionate, 1-(3,4-dimethoxyphenyl)-4,4-dimethyl-1,3-pentanedione, cinoxate, methyl O-aminobenzoate, 3-(4-methylbenzylidene) camphor, octyltriazine, methylenebisbenzotriazolyltetramethylbutylphenol.

[0025] The blending amount of component (C) in the present invention is 5.0 to 20.0% by mass based on the total amount of the oil-in-water type emulsified cosmetic. More preferably, it is 7.0 to 18.0% by mass. Within this range, a sufficient ultraviolet ray protection effect, a fresh feeling, a moisturizing feeling, and a smooth feeling can be imparted. On the other hand, if there is too much ultraviolet absorber, stickiness will occur, and the smooth feeling and the effect of preventing secondary adhesion tend to be impaired.

[0026] In the present invention, component (C) can be used alone or in combination of two or more.

[0027] The aqueous phase thickener in which the viscosity decreases due to an increase in the electrolyte concentration of component (D) is a thickener having a function of thickening the aqueous phase and whose viscosity decreases due to the presence of the electrolyte. The property that the viscosity decreases due to an increase in the electrolyte concentration in the composition, like component (D), can generally be rephrased as having low salt tolerance. Such a thickener with low salt tolerance is selected from water-soluble thickeners that have conventionally been blended for the purpose of adjusting the viscosity of the aqueous phase in cosmetics and the like.

[0028] Specific examples of component (D) in the present invention include vinyl polymers such as polyvinylpyrrolidone, vinylpyrrolidone-vinyl acetate copolymer, and carboxyvinyl polymer; acrylic polymers such as sodium polyacrylate, polyethyl acrylate, polyacrylic acid alkanolamine, alkyl methacrylate-dimethylaminoethyl methacrylate copolymer, poly-2-acrylamido-2-methylpropanesulfonic acid, polymethacryloyloxytrimethylammonium, (acryloyldimethyltaurine ammonium / VP) copolymer, and dimethylacrylamide / sodium acryloyldimethyltaurine) cross-polymer. These can be blended as appropriate, but particularly carboxyvinyl polymer, acrylic acid-methyl methacrylic acid alkyl copolymer, sodium polyacrylate, (acryloyldimethyltaurine ammonium / VP) copolymer, and (sodium acrylate / sodium acryloyldimethyltaurine) copolymer are preferably used, and in particular, they can achieve a fresh feeling, a smooth feeling, and an anti-redeposition effect while being a highly moisturizing agent.

[0029] The blending amount of component (D) in the present invention is 0.05 to 1.5% by mass based on the total amount of the oil-in-water type emulsified cosmetic. More preferably, it is 0.05 to 1.0% by mass. Within this range, a fresh feeling, a smooth feeling, and an anti-redeposition effect can be imparted.

[0030] In the present invention, component (D) can be used alone or in combination of two or more.

[0031] The carbon number of the higher alcohol as component (E) used in the present invention is not particularly limited, but a monovalent linear saturated alcohol having 16 or more carbon atoms is preferred, and further, a monovalent linear saturated alcohol having 16 to 22 carbon atoms is preferred from the viewpoints of stability and usability. For example, cetyl alcohol, stearyl alcohol, behenyl alcohol, etc. can be mentioned.

[0032] The blending amount of component (E) in the present invention is not particularly limited, but is preferably 0.1 to 2% by mass based on the total amount of the oil-in-water type emulsified cosmetic. Component (E) is usually used to thicken the cosmetic and adjust it to a texture with richness. Generally, as the amount of component (E) increases, the elongation becomes heavy and the feeling of use is accompanied by an oily feeling, and the fresh feeling and the smooth feeling are impaired. However, within this range, by combining with component (A) an anionic surfactant, while imparting a high moisturizing feeling, thixotropy is exhibited, the fresh feeling of the preparation is not impaired, and both the moisturizing feeling and the smooth feeling can be achieved. Furthermore, component (E) also plays a role in imparting a high ultraviolet ray protection effect, and with the said blending amount, the problems of the present application can be achieved.

[0033] In the present invention, component (E) can be used alone or in combination of two or more.

[0034] The water-retaining paste oil of component (F) used in the present invention may be any oil agent having a water-retaining power equal to or more than its own weight in the following water-retaining test, and is not particularly limited. The paste oil in the present invention is semi-solid at 25°C and has a melting point of 25 to 70°C. (Water-retaining test) Heat 10 g of the oil agent to be tested to 50°C, and gradually add water at 50°C while stirring until water drains from the oil agent. Leave it at room temperature for one day and night. Then, remove the separated water and measure the amount (weight g) of water retained by the oil agent. This value is divided by the oil agent amount of 10 g and multiplied by 100 to obtain the water-retaining power (%). As a result of this water-retaining test, an oil agent having a water-retaining power of 100% or more corresponds to component (F).

[0035] Specific examples of component (F) in the present invention include glyceryl oligoester of (adipic acid / 2-ethylhexanoic acid / stearic acid), N-lauroyl-L-glutamic acid di(phytosteryl / behenyl / 2-octyldodecyl), N-lauroyl-L-glutamic acid di(cholesteryl / behenyl / octyldodecyl), dipentaerythritol fatty acid ester, mixed fatty acid triglyceride, glyceryl tri(caprylic / capric / myristic / stearic acid), hydrogenated castor oil stearate, and in addition, phytosteryl isostearate, phytosteryl oleate, phytosteryl hydroxystearate, phytosteryl macadamia nut fatty acid, phytosteryl branched fatty acid (C12-31), dimer dilinoleic acid (phytosteryl / isostearyl / cetyl / stearyl / behenyl), dimer dilinoleic acid (isostearyl / phytosteryl), dimer dilinoleic acid dimer dilinoleyl bis(behenyl / isostearyl / phytosteryl) and other phytosterol derivatives, lanolin, lanolin alcohol, lanolin fatty acid, lanolin acetate and other lanolin derivatives, and cholesteryl hydroxy fatty acid, cholesteryl branched fatty acid and other cholesterol derivatives. Preferably, glyceryl oligoester of (adipic acid / 2-ethylhexanoic acid / stearic acid), N-lauroyl-L-glutamic acid di(phytosteryl / behenyl / 2-octyldodecyl), N-lauroyl-L-glutamic acid di(cholesteryl / behenyl / octyldodecyl), more preferably, glyceryl oligoester of (adipic acid / 2-ethylhexanoic acid / stearic acid) may be mentioned.

[0036] The blending amount of component (F) in the present invention is not particularly limited, but is preferably 0.1 to 3.0% by mass based on the total amount of the oil-in-water type emulsified cosmetic. Within this range, a moist feeling can be imparted without impairing the fresh feeling, smooth feeling, and secondary adhesion resistance effect.

[0037] In the present invention, component (F) can be used alone or in combination of two or more.

[0038] In the water-in-oil type sunscreen cosmetic of the present invention, in addition to the above essential components, it is also possible to blend components generally used in cosmetics etc. as required. For example, pearl agents, moisturizing agents, water-soluble polymers other than component (B) and (D), fragrances, bactericides, preservatives, antioxidants, pH adjusters, chelating agents, anti-inflammatory agents, antioxidants, cooling agents, additives such as herbal extracts and vitamins can be blended at appropriate times. The blending ratio when these components are contained can be appropriately selected according to their types and purposes, and one type can be used alone, or two or more types can be used in appropriate combinations.

Examples

[0039] The present invention will be further described below with reference to examples. These examples do not limit the present invention in any way. Also, the formulations of water-in-oil type sunscreen cosmetics are shown in the examples and comparative examples in the table.

[0040] <Evaluation of a fresh feeling of use> Regarding the evaluation test of the fresh feeling of use during application, regarding the touch when 0.5 g of the evaluation sample was applied to the face, 10 professional judges scored according to the following evaluation criteria as to whether they particularly felt a unique, bursting fresh touch, and according to the average score, 4.0 or more was rated as ◎, 3.0 or more and less than 4.0 was rated as ○, 2.0 or more and less than 3.0 was rated as △, and less than 2.0 was rated as ×. (Evaluation criteria) 5: Very fresh 4: Fresh 3: Neither can be said 2: Not fresh 1: Do not feel fresh at all

[0041] <Moisturizing feeling> Regarding the evaluation test of the moisturizing feeling, regarding the touch when 0.5 g of the evaluation sample was applied to the face, 10 professional judges scored according to the following evaluation criteria, and according to the average score, 4.0 or more was rated as ◎, 3.0 or more and less than 4.0 was rated as ○, 2.0 or more and less than 3.0 was rated as △, and less than 2.0 was rated as ×. (Evaluation criteria) 5: Feel a very strong moisturizing feeling 4: Feel a moisturizing sensation 3: Can't say either way 2: Don't feel a moisturizing sensation 1: Don't feel any moisturizing sensation at all

[0042] <Smooth feeling> For the evaluation test of the smooth feeling, 10 professional judges scored according to the following evaluation criteria regarding the touch 30 minutes after applying 0.5 g of the evaluation sample to the face. According to the average score, 4.0 or more is ◎, 3.0 or more and less than 4.0 is ○, 2.0 or more and less than 3.0 is △, and less than 2.0 is ×. (Evaluation criteria) 5: Feel a very smooth feeling 4: Feel a smooth feeling 3: Can't say either way 2: Don't feel a smooth feeling 1: Don't feel any smooth feeling at all

[0043] <Evaluation method for secondary adhesion resistance effect> Samples were prepared according to the SPF value measurement method specified in ISO-24444. A composition of 2 mg / cm2 was uniformly applied to a Helioplate HD6 (HELIOPLATE (registered trademark) HD6, manufactured by HerioScreen Lab., plate size: 5 cm × 5 cm, material: PMMA), and the SPF value was measured using an SPF analyzer UV-2000S (manufactured by Sanyo Trading Co., Ltd.). Next, the plate on which the above sample preparation was performed was placed on a tissue paper with the coated surface facing down, and a 500 g load was placed on the plate for 10 minutes to adhere it to the tissue paper, and then the SPF value was measured again. The percentage of the SPF value after adhesion relative to the SPF value before adhesion was calculated, and that value was taken as the residual rate (%). (Evaluation criteria) ◎: Residual rate of 75% or more ○: Residual rate of 50% or more and less than 75% △: Residual rate of 25% or more and less than 50% ×: Residual rate of less than 25%

Table 3

[0047] In Example 1, even though no ultraviolet absorber is blended, a fresh feeling in use and a smooth feeling after application can be achieved simultaneously, and it also has an excellent anti-redeposition effect. In Example 2, by further blending a water-retaining paste oil agent, while maintaining the fresh feeling in use, the smooth feeling after application, and the anti-redeposition effect, the moisturizing feeling can be improved. For Examples 3 to 25, it was also confirmed that the effects of the present invention are excellent. Examples 26 and 27 are examples in which other paste oil agents are blended instead of the water-retaining paste oil agent. Compared with Example 2, although the effects of the invention are not impaired, the balance of the moisturizing feeling, the smooth feeling after application, and the anti-redeposition effect is more favorable with the water-retaining paste oil agent. Looking at Comparative Examples 1 to 3 in which the anionic surfactant is changed to a nonionic surfactant or deleted, it can be seen that the distinct fresh feeling in use disappears, and the smooth feeling after application and the anti-redeposition effect are also reduced. Also, in Comparative Example 5 in which a similar polymer of Component (B) is blended, not only does the fresh feeling in use disappear, but also the smooth feeling after application and the anti-redeposition effect are significantly deteriorated. From this, it can be seen that Component (B) cannot solve the problem unless it is the polymer specified in the present application. In Comparative Examples 7 to 9 in which Component (D) is replaced with another polymer compound, the fresh feeling in use disappears, and the smooth feeling after application and the anti-redeposition effect also tend to deteriorate. In Comparative Examples 11 to 12 in which Component (E) is replaced with another solid oil agent, the fresh feeling in use disappears, and the smooth feeling after application and the anti-redeposition effect also tend to deteriorate. From the above results, it can be seen that the cosmetic of the present application has a fresh feeling in use, and has a smooth feeling, a moisturizing feeling, and an anti-redeposition effect after application. This solves the problems of the water-in-oil type sunscreen cosmetic described at the beginning, and is the result of meeting the needs of consumers.
