Abstract
Description
Technical Field
[0001] The present invention relates to a cosmetic for correcting unevenness, and more particularly to an oily or water-in-oil emulsified cosmetic, which is a low-viscosity cosmetic formulated with polar oils such as ultraviolet absorbers, and can continuously exert an excellent unevenness correcting effect (pore correcting effect). Background Art
[0002] One of the functions required of basic cosmetics (primer, foundation) is a bump correction function that can make the bumps and bumps of the skin such as pores less noticeable. In conventional bump correction cosmetics, oil dispersed with powder enters the pores and other concave parts to correct the bumps and bumps of the skin, and the light reflection or diffusion or interference effect of the powder is used to achieve the effect of blurring the bumps and bumps and making them less noticeable.
[0003] Patent document 1 discloses a cosmetic that combines a pore / texture correction effect with a lustrous makeup by blending a hydrophilic spherical powder in the inner phase (aqueous phase) and a hydrophobic plate-like powder in the outer phase (oil phase) of a water-in-oil emulsion cosmetic.
[0004] Patent document 2 discloses a skin external preparation which is excellent in covering aged pores with enlarged openings on the skin surface by combining and blending a hemispherical or hemi-ellipsoidal powder with a plate-like powder containing a (meth)acrylate polymer as a main component.
[0005] In addition, Patent Document 3 discloses a cosmetic for correcting unevenness, which comprises (a) fumed hydrophobic silica, (b) octamethyltrisiloxane and / or decamethyltetrasiloxane, (c) batyl alcohol, and (d) powders other than (a) in specified amounts. The cosmetic does not contain so-called microplastic beads and has excellent feel during use and stability over time.
[0006] As described above, various improvements have been made to cosmetics that have the effect of correcting unevenness such as pores. However, when ester oils and ultraviolet absorbers are added to improve the usability of low-viscosity base cosmetics and impart ultraviolet protection, there is a problem that the cosmetic film becomes thinner over time, and the powder enters the concave parts such as pores, making the unevenness more conspicuous.

[0012] Problem that the invention aims to solve
[0013] An object of the present invention is to provide a cosmetic product for correcting unevenness (pores) of low viscosity and excellent in correcting unevenness of the skin, particularly pores, and capable of maintaining the excellent correcting effect for a long period of time.
[0014] Solutions for solving problems
[0015] The present inventors have conducted intensive studies to solve the above-mentioned problems and have found that a combination of powder (excluding coloring pigments) and coloring pigments and a prescribed amount of oil gelling agent in a low-viscosity cosmetic containing polar oils can provide a roughness correction effect for a long period of time, thereby completing the present invention.
[0016] That is, the present invention provides an oily or water-in-oil emulsified cosmetic comprising:
[0017] (A) powder (excluding coloring pigments);
[0018] (B) 0.2 to 15% by mass of a coloring pigment;
[0019] (C) polar oils; and
[0020] (D) 2 to 10% by mass of an oil gelling agent.
[0021] Effects of the Invention
[0022] The oily or water-in-oil emulsified cosmetic of the present invention has an excellent effect of correcting unevenness of the skin, especially making pores less noticeable, and this effect can last for a long time. Therefore, there is no need to frequently touch up the makeup. In addition, by adjusting the amount of coloring pigments, it is possible to achieve an extremely natural makeup like a bare face without any makeup. In addition, if an ester oil as a polar oil and an ultraviolet absorber are combined, a basic cosmetic with good usability and excellent ultraviolet protection effect can be prepared. DETAILED DESCRIPTION
[0023] The oily or water-in-oil emulsified cosmetic (hereinafter also referred to as "cosmetics") of the present invention contains (A) powder (excluding coloring pigments); (B) coloring pigments; (C) polar oils; and (D) oil gelling agents as essential ingredients.
[0024] (A)Powder
[0025] The "powder" (also referred to as "component (A)") in the cosmetic of the present invention may be an inorganic powder or an organic powder conventionally used in cosmetics and the like.
[0026] Examples of the inorganic powder include talc, kaolin, mica (mica, sericite, muscovite, phlogopite, synthetic mica, red mica, biotite, etc.), vermiculite, magnesium carbonate, calcium carbonate, aluminum silicate, barium silicate, calcium silicate, magnesium silicate, strontium silicate, metal tungstate, magnesium, silica (silicic acid anhydride), zeolite, barium sulfate, calcined calcium sulfate (plaster of Paris), calcium phosphate, fluoroapatite, hydroxyapatite, ceramic powder, metal soaps (for example, zinc myristate, calcium palmitate, aluminum stearate, etc.), boron nitride, and particulate titanium dioxide and particulate zinc oxide.
[0027] Examples of the organic powder include polyamide resin powder (nylon powder), polyethylene powder, polymethyl methacrylate powder, polystyrene powder, styrene and acrylic acid copolymer resin powder, benzoguanamine resin powder, polytetrafluoroethylene powder, and cellulose powder.
[0028] The powder (component (A)) formulated in the cosmetic of the present invention is preferably a powder with a hydrophobic surface and dispersed in oil. Therefore, in the case of a powder of a hydrophilic material, it is preferably formulated in the form of a powder with a hydrophobic surface. The treating agent used for the surface hydrophobization is not particularly limited, and for example, hydrophobic treating agents such as organosilicon compounds, fluorine-modified organosilicon compounds, fluorine compounds, higher fatty acids, higher alcohols, fatty acid esters, metal soaps, amino acids or alkyl phosphates can be used.
[0029] The particle shape of the powder is not particularly limited, and powders in shapes such as spheres, plates, needles, etc. can be used. The average particle size of the powder is also not particularly limited, but from the viewpoint of ultraviolet protection effect, it is preferred to contain microparticles of titanium dioxide or microparticles of zinc oxide, and from the viewpoint of usability, it is preferred to contain spherical powders such as spherical silica.
[0030] The amount of powder (component (A)) in the cosmetics of the present invention is not particularly limited as long as it is an amount that exerts a concavoconvex correction effect. Generally, it is preferably mixed in a range of 1 to 50% by mass relative to the total amount of the cosmetics. The amount of powder (component (A)) can be appropriately set within the aforementioned preferred range. For example, the lower limit of the amount range relative to the total amount of the cosmetics can be set to 5% by mass or more, 8% by mass or more, 10% by mass or more, or 12% by mass or more. The upper limit of the amount range relative to the total amount of the cosmetics can be set to 40% by mass or less, 35% by mass or less, 30% by mass or less, or 20% by mass or less.
[0031] (3) Coloring Pigments
[0032] The "coloring pigment" (also referred to as "component (B)") in the cosmetic of the present invention is a pigment powder that is added as a colorant in the cosmetic. The "coloring pigment" (component (B)) includes: colored pigments such as iron oxides, white pigments such as pigment-grade titanium dioxide and pigment-grade zinc oxide, pearlescent pigments, organic pigments, etc.
[0033] Examples of the coloring pigment (component (B)) include white pigments such as titanium dioxide and zinc oxide, inorganic red pigments such as iron oxides (iron oxide red) and iron titanate, inorganic brown pigments such as γ-iron oxide, inorganic yellow pigments such as iron oxide yellow and yellow ochre, inorganic black pigments such as iron oxide black, carbon and low-valent titanium oxide, inorganic purple pigments such as manganese violet and cobalt violet, inorganic green pigments such as chromium oxide green, chromium hydroxide and cobalt titanate, inorganic blue pigments such as ultramarine and Prussian blue, titanium dioxide-coated mica, titanium dioxide-coated bismuth oxychloride, titanium dioxide-coated talc, Pearlescent pigments such as colored titanium dioxide coated mica, bismuth oxychloride, and fish scale foil; metal powder pigments such as aluminum powder and copper powder; organic pigments such as Red No. 202, Red No. 205, Red No. 220, Red No. 228, Red No. 405, Orange No. 203, Orange No. 204, Yellow No. 205, Yellow No. 401, and Blue No. 404; organic pigments such as zirconium, barium, and aluminum lakes including 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.
[0034] The amount of the coloring pigment (component (B)) in the cosmetic of the present invention is in the range of 0.2 to 15% by mass relative to the total amount of the cosmetic. When the amount is less than 0.2% by mass, a sufficient unevenness correction effect cannot be obtained. When the amount exceeds 15% by mass, although an unevenness correction effect can be obtained, a thick coating feeling will be generated, which is not preferred.
[0035] It should be noted that, in order to achieve a natural look like bare skin without any makeup when applying the cosmetics of the present invention, it is effective to reduce the amount of coloring pigments incorporated. For example, by making it 5% by mass or less, preferably 3% by mass or less, and more preferably 2% by mass or less relative to the total amount of the cosmetics, an extremely natural look can be achieved.
[0036] (C) Polar oil
[0037] The "polar oil" (also referred to as "component (C)") of the present invention refers to an oil component (excluding silicone oil) that is liquid at room temperature (25°C) and can be incorporated into cosmetics, and has a high polarity, for example, preferably an oil component having an IOB value of 0.10 or more, 0.11 or more, 0.12 or more, or 0.13 or more. The upper limit of the IOB value of the polar oil (component (C)) is not particularly limited, and may be, for example, 0.50 or less, 0.45 or less, or 0.40 or less.
[0038] Here, "IOB value" is an abbreviation of "Inorganic / Organic Balance", which is a value indicating the ratio of the inorganic value to the organic value, and is one of the indicators indicating the degree of polarity of an organic compound. Specifically, the IOB value is expressed as IOB value = inorganic value / organic value. For each of the "inorganic value" and the "organic value", for example, the "organic value" of a carbon atom in a molecule is 20, and the "inorganic value" of a hydroxyl group is 100. In this way, corresponding "inorganic values" and "organic values" are set according to various atoms or functional groups. By accumulating the "inorganic values" and "organic values" of all atoms and functional groups in the organic compound, the IOB value of the organic compound can be calculated (for example, see Yoshio Koda, "Organic Concept Map - Fundamentals and Applications -", p. 11-17, Sankyo Publishing, published in 1984).

In addition, when a UV absorber is added, a cosmetic having UV protection can be prepared. The ester oil and the UV absorber can be used alone or in the form of a mixture of two or more. From the viewpoint of obtaining an excellent UV protection effect (high SPF), it is preferred to include a UV absorber.
[0055] The amount of the polar oil (component (C)) in the cosmetic of the present invention is not particularly limited. In order to obtain smooth usability, it is preferably 5% by mass or more, more preferably 8% by mass or more, and even more preferably 10% by mass or more relative to the total amount of the cosmetic. The upper limit of the amount of the polar oil is not particularly limited. For example, it can be 98% by mass or less or 97% by mass or less relative to the total amount of the cosmetic.
[0056] (D) Oil gel
[0057] "Oil gel" (also referred to as "component (D)") is a component having the function of thickening (gelling) the oil by dissolving in the oil or swelling in the oil. The "oil gel" (component (D)) in the cosmetic of the present invention has the aforementioned thickening (gelling) function particularly for polar oil (component (C)), and can be appropriately selected from substances that can be used in cosmetics, etc. For example, cross-linked silicone powder that is swollen by silicone oil and has the effect of increasing the apparent viscosity of the silicone oil is considered to have no or only a weak thickening (gelling) function for polar oil, and therefore is not included in the oil gel (component (D)) of the present invention.
[0058] Specific examples of the oleogel (component (D)) preferably used in the present invention include amino acid-based gelling agents, sugar fatty acid esters, waxes, fatty acids or salts thereof that are solid at room temperature (25° C.), glycerol fatty acid esters, and organically modified clay minerals. These oleogels may be used alone or in combination of two or more.
[0059] Examples of the amino acid-based gelling agent include dibutyl lauroyl glutamide, dibutyl ethylhexanoyl glutamide, polyamide-8, and polyamide-3.
[0060] Sugar fatty acid esters include dextrin fatty acid esters and sucrose fatty acid esters.
[0061] Dextrin fatty acid ester is an ester of dextrin or reduced dextrin and a higher fatty acid. As long as it is a substance commonly used in cosmetics, it can be used without particular limitation. Dextrin or reduced dextrin preferably uses a substance with an average sugar polymerization degree of 3 to 100. In addition, as the fatty acid constituting the dextrin fatty acid ester, a saturated fatty acid with a carbon number of 8 to 22 is preferably used. Specifically, dextrin palmitate, dextrin oleate, dextrin stearate, dextrin myristate, dextrin palmitate / 2-ethylhexanoate, etc. can be mentioned.
[0062] Sucrose fatty acid esters can preferably be used, wherein the fatty acid is linear or branched, saturated or unsaturated, and has 12 to 22 carbon atoms. Specific examples thereof include sucrose caprylate, sucrose caprate, sucrose laurate, sucrose myristate, sucrose palmitate, sucrose stearate, sucrose oleate, and sucrose erucate.

[0067] The oil gelling agent (component (D)) used in the cosmetic of the present invention preferably contains at least one selected from the group consisting of amino acid gelling agents, sugar fatty acid esters, waxes, fatty acids that are solid at room temperature, and organic modified clay minerals. The cosmetic of the present invention preferably uses an amino acid gelling agent, and among them, polyamide-8 is particularly preferably used.
[0068] The amount of the oil gel (component (D)) in the cosmetic of the present invention is 2 to 10% by mass, preferably 2 to 8% by mass, and more preferably 2 to 5% by mass, relative to the total amount of the cosmetic. If the amount is less than 2% by mass, a sufficient unevenness correction (pore correction) effect cannot be obtained. If the amount exceeds 10% by mass, stickiness may occur.
[0069] The cosmetics of the present invention are "oily or water-in-oil emulsified cosmetics" (hereinafter collectively referred to as "oily cosmetics"). "Oil-based cosmetics" refer to cosmetics in which oil is first felt when applied to the skin, and they may contain a small amount of water or be in a water-free (anhydrous) form.
[0070] The oily cosmetic (in a general sense) of the present invention preferably contains water in an amount of 25% by mass or less, more preferably 20% by mass or less.
[0071] The cosmetics of the present invention are low-viscosity cosmetics with excellent unevenness correction (pore correction) effects. Therefore, the viscosity of the cosmetics of the present invention is preferably set to 10000 mPa·s or less. By adjusting to such a low viscosity, the feel is smooth when used, and a natural makeup can be actually felt.
[0072] In the cosmetics of the present invention, in addition to the above-mentioned components (A) to (D), other optional components that can be conventionally formulated in cosmetics, etc., may be formulated within the range that does not hinder the effects of the present invention. Other optional components include: oils other than polar oils, surfactants, moisturizers, film-forming agents, chelating agents, lower alcohols (ethanol, isopropanol, etc.), pH adjusters (buffers such as lactic acid / sodium lactate, citric acid / sodium citrate, etc.), preservatives, antioxidants, edible flavors (ingredients), and various drugs, etc., but are not limited to these.
[0073] The oil components other than polar oils can be selected from those that are generally used in cosmetics and are liquid, semi-solid or solid at room temperature (25° C.), and specifically include hydrocarbon oils, higher fatty acids, higher alcohols, fats and oils, silicone oils and the like.
[0074] Examples of the hydrocarbon oil include liquid paraffin and squalane.

[0076] Higher alcohols include: straight-chain alcohols such as lauryl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, myristyl alcohol, oleyl alcohol, and cetostearyl alcohol; branched-chain alcohols such as monostearyl glyceryl ether (baty alcohol), 2-decyltetradecyl alcohol, lanolin alcohol, cholesterol, phytosterols, hexyldodecanol, isostearyl alcohol, and octyldodecanol.
[0077] Examples of the silicone oil include chain silicone oils or cyclic silicone oils such as dimethyl polysiloxane (polydimethylsiloxane), phenyl-modified silicone (diphenylsiloxyphenyl trimethicone, etc.), and alkyl-modified silicone (octyl methylsiloxane, etc.).
[0078] The surfactant is not particularly limited, and examples thereof include silicone-based surfactants, and among them, examples thereof include silicone-based surfactants having an HLB value of 6 or less, such as PEG-10 polydimethylsiloxane and PEG-9 dimethylsiloxyethyl polydimethylsiloxane.
[0079] The present invention includes silicone compounds having a polyoxyalkylene group and an amide alkyl group in a branched polymer, such as PEG-12 methyl ether lauryl PEG-5 amidopropyl dimethicone.
[0080] Specific examples of moisturizing agents include: diols (ethylene glycol, propylene glycol, 1,3-butylene glycol, 1,3-propanediol, etc.); triols (glycerol, etc.); tetraols (pentaerythritol, such as 1,2,6-hexanetriol); pentaols (xylitol, etc.); polyol polymers (diglycerol, dipropylene glycol, triethylene glycol, polyethylene glycol, etc.); sugar alcohols (sorbitol, mannitol, etc.); hyaluronic acid, etc.
[0081] The cosmetics of the present invention can be produced by a method commonly used in oily or water-in-oil emulsified cosmetics. For example, in the case of oily (anhydrous) cosmetics, the cosmetics can be produced by stirring and mixing the oily components in any manner as needed, and dispersing the powder in the mixture. In the case of water-in-oil emulsified cosmetics, the cosmetics can be produced by stirring and mixing the components (including powder) constituting the oil phase in any manner as needed, and stirring and mixing the components constituting the water phase in any manner as needed, and stirring the water phase in the oil phase to mix and emulsify the components.
[0082] The cosmetic of the present invention is an oily cosmetic with low viscosity, a smooth feel, and excellent unevenness correction (pore correction) effect. Therefore, it is suitable for being provided in the form of a makeup cosmetic such as a primer or foundation. In particular, a primer in which the amount of coloring pigment is adjusted to 5% by mass or less can achieve a natural makeup look as if no makeup is worn at all.
[0083] Example
[0084] 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 is expressed in mass %.
[0085] Water-in-oil emulsified cosmetics were prepared according to conventional methods using the formulations given in Tables 1 to 4. The properties of the cosmetics of each example were measured and evaluated by the following methods.
[0086] "Pore correcting effect", "smooth usability", and "natural finish"
[0087] Ten professional panelists used the cosmetics of each example and evaluated them according to the following criteria.
[0088] <Evaluation Criteria>
[0089] A: 9 or more people rated it as excellent
[0090] B: 6 to 8 people rated it as excellent
[0091] C: Excellent if less than 5 people evaluate
[0092] As shown in Table 1, even when the type of powder was changed, the cosmetics of the present invention containing the essential ingredients (A) to (D) in the prescribed amounts were rated excellent by most of the panelists in terms of pore correction effect, usability, and natural makeup. However, Example 5, in which the amount of polar oil contained was less than 10% by mass, had slightly poor spreadability during application.
[0093] The results shown in Table 2 show that satisfactory evaluations can be obtained in each item even when the type of the oil gel is changed, but when the amount of the oil gel blended is less than 2% by mass, a sufficient pore correcting effect cannot be obtained.
[0094] The results in Table 3 show that in order to obtain an excellent pore correcting effect, powder (component (A)) must be added (Comparative Example 3).
[0095] In addition, in Comparative Example 4 in which the polyamide-8 of Example 5 (Table 1) was replaced with an equal amount of silicone gel (containing cross-linked silicone powder), and in Comparative Example 5 in which the amount of the silicone gel was adjusted so that the actual amount of cross-linked silicone powder was approximately equal to that of the polyamide-8 of Example 5, sufficient pore correction effect was not obtained.
[0096] The results of Table 4 show that the excellent pore correction effect requires the addition of a coloring pigment (Comparative Example 6). On the other hand, when the amount of the coloring pigment exceeds 5% by mass, although the problem of improving the uneven correction effect of the present invention is solved, a natural makeup cannot be achieved (Examples 12 and 13).
