Description

[Technical field]

[0001] The present invention relates to an oil-in-water emulsion cosmetic preparation. More specifically, the present invention relates to an oil-in-water emulsion cosmetic preparation that does not contain ethylhexyl methoxycinnamate and octocrylene, which are liquid ultraviolet absorbents that have been widely used in the past, and that has excellent emulsion stability and high ultraviolet protection effect even with a small oil content. [Background technology]

[0002] In oil-in-water emulsion cosmetics exhibiting ultraviolet protection effects, such as sunscreen cosmetics, oil-based ultraviolet absorbers and powdery ultraviolet scattering agents have conventionally been blended in appropriate combinations to effectively block ultraviolet rays from the UVA region to the UVB region. However, blending a large amount of oil-based ultraviolet absorbers results in a sticky feel, while blending a large amount of ultraviolet scattering agents results in a powdery feel when used and makes the skin look unnaturally white.

[0003] Patent Document 1 describes that by incorporating four specific types of ultraviolet absorbing agents, a high SPF (Sun Protection Factor) can be achieved even without incorporating an ultraviolet scattering agent or with a reduced amount of ultraviolet scattering agent.

[0004] On the other hand, it has been pointed out that octyl methoxycinnamate (ethylhexyl methoxycinnamate) and octocrylene, which are commonly used as UV absorbers, are irritating, and instead, sunscreen cosmetics have been proposed that incorporate specific UV scattering agents (such as rutile-type crystalline titanium dioxide) to ensure UV protection effects (Patent Document 2).

[0005] However, the above-mentioned liquid ultraviolet absorbents not only have ultraviolet absorbing ability themselves, but also act as good solvents for solid or poorly soluble ultraviolet absorbents that are co-blended (for example, see Patent Document 3). Therefore, when these liquid ultraviolet absorbents are not blended, the amount of polar oil that serves as a solvent must be increased in order to prevent the precipitation or destabilization of the other ultraviolet absorbents, resulting in a problem of stickiness.

[0007] Therefore, an object of the present invention is to provide an oil-in-water emulsion cosmetic that not only exhibits high UV protection ability but also has excellent emulsion stability and usability, even without blending the liquid UV absorbers ethylhexyl methoxycinnamate and octocrylene and with a reduced amount of polar oil. [Means for solving the problem]

[0008] As a result of intensive research aimed at solving the above problems, the present inventors discovered that by combining and blending a specific water-soluble absorbent and an oily solid absorbent as an ultraviolet absorbent, and further introducing an α-gel structure into the emulsion system, it is possible to obtain an oil-in-water emulsion cosmetic that exhibits high ultraviolet protection capabilities while also being excellent in stability and usability, and thus completed the present invention.

[0009] That is, the present invention provides (A) (a1) a sulfonic acid group-containing water-soluble ultraviolet absorber, (a2) bisethylhexyloxyphenol methoxyphenyl triazine, (a3) diethylaminohydroxybenzoylhexyl benzoate, and (a4) ultraviolet absorbers including ethylhexyl triazone; (B) polar oil, (C) a higher alcohol, and (D) a nonionic surfactant; The present invention provides an oil-in-water emulsion cosmetic, characterized in that the total blend amount of the (a2) bisethylhexyloxyphenol methoxyphenyl triazine, (a3) ​​diethylamino hydroxybenzoyl hexyl benzoate, (a4) ethylhexyl triazone, and (B) polar oil is 45 mass% or less. Effect of the Invention

[0010] The oil-in-water emulsion cosmetic of the present invention does not contain the liquid ultraviolet absorbents ethylhexyl methoxycinnamate and octocrylene, and even when the amount of polar oil contained is reduced, it has excellent emulsion stability, exhibits high ultraviolet protection effect, and is non-irritating and has a good feel when used. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Specific examples of polar oils (B component) include, but are not limited to, diisopropyl sebacate, pentaerythrityl tetraethylhexanoate, cetyl ethylhexanoate, jojoba oil, di(phytosteryl / octyldodecyl) lauroyl glutamate, triisostearin, glyceryl diisostearate, triethylhexanoin, dimer dilinoleate (phytosteryl / behenyl), dimer dilinoleate (phytosteryl / isostearyl / cetyl / stearyl / isostearyl / cetyl / stearyl / behenyl), isopropyl palmitate, phytosteryl macadamia nut fatty acid, pentaerythrityl tetra(behenic acid / benzoic acid / ethylhexanoic acid), ethylhexyl palmitate, myristyl myristate, isopropyl myristate, tripropylene glycol dipivalate, isodecyl neopentanoate, etc. Furthermore, liquid ultraviolet absorbers may also be included in the polar oil (B component). Therefore, in the present invention, when calculating the total blending amount of each of the A component and the B component, the oil-soluble polar liquid ultraviolet absorber is included in the polar oil (B component).

[0022] The amount of polar oil (B component) in the emulsion cosmetic of the present invention must be such that the total amount of (a2) bisethylhexyloxyphenol methoxyphenyl triazine, (a3) ​​diethylamino hydroxybenzoyl hexyl benzoate, (a4) ethylhexyl triazone, and (B) polar oil is 45% by mass or less. If this total amount exceeds 45% by mass, a stable emulsion cannot be obtained. Needless to say, 45% by mass or less includes all values ​​such as 44% by mass, 43% by mass, 42% by mass, 41% by mass, 40% by mass, 39% by mass or less, 38% by mass or less, 37% by mass or less, 36% by mass or less, and 35% by mass or less.

[0023] The blend amount of the polar oil (component B) is not particularly limited as long as it falls within the range that satisfies the above conditions, but from the viewpoint of imparting luster to the skin after application, it is preferably 6 mass % or more.

[0024] In the emulsion cosmetic of the present invention, it is preferable to set the ratio [(B) / (a2+a3+a4)] of the amount of polar oil (component B) to the total amount of (a2) bisethylhexyloxyphenol methoxyphenyl triazine, (a3) ​​diethylamino hydroxybenzoyl hexyl benzoate, and (a4) ethylhexyl triazone to 0.6 or more, since this further improves stability. The upper limit of this ratio [(B) / (a2+a3+a4)] is not particularly limited, but from the viewpoint of usability of the cosmetic, it is preferable to set it to about 5 or less.

[0025] (C) Higher alcohol The higher alcohol (component C) used in the sunscreen cosmetic of the present invention is not particularly limited as long as it is a higher alcohol having 6 or more carbon atoms that can be used in the fields of cosmetics, medicines, quasi-drugs, etc., and includes saturated linear monohydric alcohols and unsaturated monohydric alcohols. Examples of saturated linear monohydric alcohols include dodecanol (lauryl alcohol), tridodecanol, tetradodecanol (myristyl alcohol), pentadecanol, hexadecanol (cetyl alcohol), heptadecanol, octadecanol (stearyl alcohol), nonadecanol, icosanol (arachyl alcohol), henicosanol, docosanol (behenyl alcohol), tricosanol, tetracosanol (carnaubyl alcohol), pentacosanol, and hexacosanol (ceryl alcohol). Examples of unsaturated monohydric alcohols include elaidyl alcohol. In the present invention, saturated linear monohydric alcohols are preferred from the viewpoint of stability over time.

[0026] The higher alcohol (C) may be one or more of the above. In the present invention, it is preferable to use a mixture of two or more aliphatic alcohols, and a mixture having a melting point of 50° C. or higher is particularly preferable in terms of stability. For example, a combination of stearyl alcohol and behenyl alcohol is particularly preferable.

[0027] The blending amount of (C) higher alcohol is preferably 0.1 to 10 mass% and more preferably 0.1 to 7 mass% based on the total amount of the cosmetic. If the blending amount of (C) higher alcohol is less than 0.1 mass% or more than 10 mass%, sufficient emulsion stability may not be obtained.

Specific examples include polyethylene glycol fatty acid esters, polyoxyethylene fatty acid glyceryl, polyoxyethylene-methylpolysiloxane copolymers, fatty acid polyoxyethylene sorbitan, polyoxyethylene alkyl ethers, maltitol hydroxy fatty alkyl ethers, alkylated polysaccharides, alkyl glucosides, sucrose fatty acid esters, polyoxyethylene hydrogenated castor oil glyceryl, polyoxyethylene sorbitol fatty acid esters, polyoxyethylene-polyoxypropylene block copolymers, tetrapolyoxyethylene-tetrapolyoxypropylene-ethylenediamine condensates, polyoxyethylene-beeswax-lanolin derivatives, alkanolamides, polyoxyethylene-propylene glycol fatty acid esters, polyoxyethylene-alkylamines, polyoxyethylene-fatty acid amides, alkylethoxydimethylamine oxides, and trioleyl phosphates. In the cosmetic composition of the present invention, particularly preferred examples include hydrophilic nonionic surfactants having an HLB of 8 or more, such as beheneth-20, polysorbate 60, PEG-40 stearate, etc. One or more types of nonionic surfactants may be used.

[0029] The blending amount of the nonionic surfactant (D) is preferably 0.1 to 20 mass% and more preferably 0.3 to 5 mass% based on the total amount of the cosmetic. If the blending amount of the nonionic surfactant (D) is less than 0.1 mass% or more than 20 mass%, sufficient emulsion stability may not be obtained.

[0030] (E)Water The sunscreen cosmetic of the present invention is an oil-in-water emulsion, and therefore contains water (component E). In the present invention, the (C) higher alcohol forms an association (also called "α-gel") having a lamellar liquid crystal structure together with the (D) nonionic surfactant and (E) water. The blending ratio of the (C) higher alcohol to the (D) surfactant is preferably within the range of (C):(D)=2:1 to 25:1 (molar ratio).

[0031] The sunscreen cosmetic of the present invention may contain other optional ingredients that can be incorporated into ordinary cosmetics or quasi-drugs having a sunscreen effect, within the range that does not impair the effects of the present invention. Other optional components include, but are not limited to, powder components, colorants, moisturizers, oils (excluding (A) oil-based ultraviolet absorbers and (B) polar oils), thickeners, dispersants, preservatives, fragrances, various chemicals, and the like.

[0032] Representative examples of powder components include fine particle or pigment-grade titanium oxide and zinc oxide. Other examples include metal oxide powders other than titanium oxide and zinc oxide, extender pigments such as talc, mica, and kaolin, and polymer powders such as silica, silicone powder, polyethylene powder, polymethyl methacrylate powder, and nylon powder. The sunscreen cosmetic of the present invention has sufficient ultraviolet protection ability due to the combination of the specific ultraviolet absorbers (a1 to a4) described above, so it is not necessary to incorporate an ultraviolet scattering agent such as titanium oxide or zinc oxide. In other words, the sunscreen cosmetic of the present invention also includes an embodiment that does not contain an ultraviolet scattering agent.

[0033] As coloring materials, pigments, pearl pigments, and other pigments that are usually incorporated in makeup cosmetics can be used.Specifically, inorganic white pigments (titanium dioxide, zinc oxide), inorganic red pigments (iron oxide (red oxide), iron titanate), inorganic brown pigments (γ-iron oxide), inorganic yellow pigments (yellow iron oxide, yellow ocher), inorganic black pigments (black iron oxide, carbon, low-order titanium oxide), inorganic purple pigments (mango violet, cobalt violet), inorganic green pigments (chromium oxide, chromium hydroxide, cobalt titanate), inorganic blue pigments (ultramarine, Prussian blue), pearl pigments (titanium oxide-coated mica, titanium oxide-coated bismuth oxychloride, titanium oxide-coated talc, colored titanium oxide-coated mica, bismuth oxychloride, fish scale foil), metal powder pigments (aluminum powder, copper powder), organic pigments (Red No. 202, Red No. 205, Red No. 220, Red No. 228, Red No. 405, Orange No. 203, Examples of pigments include, but are not limited to, orange No. 204, yellow No. 205, yellow No. 401, and blue No. 404), zirconium, barium, and aluminum lake organic pigments (red No. 3, red No. 104, red No. 227, red No. 401, orange No. 205, yellow No. 4, yellow No. 202, green No. 3, and blue No. 1), natural pigments (chlorophyll, carotenoids (β-carotene), carthamine, cochineal, chalcone, curcumin, betanin, flavonol, flavone, anthocyanidin, anthraquinone, and naphthoquinone), and functional pigments (boron nitride, photochromic pigments, synthetic fluorine-containing phlogopite, iron-containing synthetic fluorine-containing phlogopite, and fine particle composite powder (hybrid fine powder)). One or more of the above pigments may be blended in combination. In the emulsion cosmetic of the present invention, these coloring materials may be blended in a dispersed form in either the internal oil phase or the external aqueous phase.

[0034] Examples of the moisturizing agent include polyhydric alcohols such as glycerin, 1,3-butylene glycol, dipropylene glycol, and propylene glycol, and water-soluble polymers such as hyaluronic acid and chondroitin sulfate.

[0035] Examples of oils (excluding (A) oil-based ultraviolet absorbents and (B) polar oils) include volatile or non-volatile liquid oils, such as hydrocarbon oils, ester oils, silicone oils, liquid fats and oils, and solid oils.

[0036] The emulsified cosmetic of the present invention is not limited to any particular one, but can be produced, for example, by dissolving (C) a higher alcohol, (D) a nonionic surfactant, and an oil at high temperature to prepare a dissolved oil part, adding the dissolved oil part to a heated aqueous phase part containing (E) water and other aqueous components, and emulsifying and cooling the mixture in a conventional manner.

[0037] The emulsion cosmetic of the present invention has a moist feel when used that is characteristic of oil-in-water emulsions, and also exhibits excellent ultraviolet protection effects due to the combination of specific ultraviolet absorbents. Therefore, the emulsion cosmetic of the present invention is suitably used in various formulations such as cream, emulsion, and liquid. The product form can be a skin care cosmetic containing a sunscreen cosmetic, or a makeup cosmetic such as a base or foundation having a sunscreen effect. EXAMPLES

[0038] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples. Unless otherwise specified, the blending amount of each component is expressed as mass % based on the total amount of the composition in which the component is blended.

[0039] Oil-in-water emulsion sunscreen cosmetics were prepared according to the formulations shown in Table 1 (lotion) and Table 2 (cream). Each sunscreen cosmetic (sample) was evaluated for the following items (1) to (4) according to the following criteria.

[0040] (1) Emulsion stability Evaluation criteria: A: No precipitation or separation was observed and it was extremely stable. B: Emulsification is possible, but precipitation was observed over time at low temperatures (0°C). C: Emulsification is possible, but the number of emulsion particles increases over time at high temperatures (37°C). D: Emulsification is possible, but separation occurs over time at room temperature.

[0041] (2) Ultraviolet protection ability (absorbance) The sample of each example was 1.75 mg / cm 2 The solution was applied to a PMMA substrate in a concentration of 1000 ppm, and the absorbance at a wavelength of 310 nm was measured using a spectrophotometer (HITACHI U-4100 Spectrophotometer).

[0042] (3) Feeling of use A practical test was carried out by a panel of experts, and the feel of the product in use was evaluated in terms of freshness and non-stickiness according to the following criteria. +:Excellent -: Inferior

[0043] (4) Shine after application A practical test was conducted by a panel of experts, and the skin luster after application was evaluated according to the following criteria. A:Excellent B: Normal C: Inferior

[0044] [Table 1]

[0045] [Table 2]

[0046] As is clear from the results shown in Tables 1 and 2, Examples 1 to 3 and 5 to 8, which satisfy all the requirements set forth in claims 1 to 6 of the present application, were excellent in stability whether in the form of a milky lotion or cream, exhibited remarkable UV protection, had a good feel when used, and were excellent in the effect of giving a gloss to the skin after application. However, Example 4, in which the ratio of (B) / (a2+a3+a4) was less than 0.6 and the amount of polar oil blended was less than 6 mass%, maintained a stable emulsion state for a short period of time and was practically problem-free, but precipitated over time at low temperatures, and the effect of giving a gloss to the skin was at an ordinary level and was problem-free, but no significant improvement in gloss was observed.

[0047] On the other hand, in Comparative Example 1, where the blending amount of oily components (a2+a3+a4+B) exceeded 45% by mass, emulsification was possible, but the emulsion became unstable over time at high temperatures. In addition, in the examples (Comparative Examples 2 and 3) where emulsification was attempted using a polymer emulsifier ((acrylates / alkyl acrylate (C10-30)) crosspolymer) that does not contain components that form α-gel (higher alcohol and nonionic surfactant) and is widely used in oil-in-water emulsion cosmetics, separation occurred over time at room temperature, and a stable emulsion could not be obtained.
