Abstract
Description
[Technical Field]
[0001] The present invention relates to an oil-based cleansing cosmetic. [Background technology]
[0002] In recent years, makeup cosmetics with excellent water and oil resistance have been developed, significantly improving makeup wear. Therefore, various types of cleansing cosmetics for cleaning makeup cosmetics have been developed, including oil-based cleansing cosmetics with high cleansing power. For example, Patent Documents 1 and 2 disclose oil-based cleansing cosmetics that contain an oil thickener to prevent dripping. However, these cleansing cosmetics often leave a sticky feeling after cleansing, and their viscosity decreases with application and rubbing, leaving the problem of dripping unresolved.
[0003] Therefore, solidified oil-based cleansing cosmetics have been developed to prevent dripping and improve usability (see, for example, Patent Documents 3 and 4). These oil-based cleansing cosmetics are characterized by the encapsulation of liquid oil within solid oil crystals. When such oil-based cleansing cosmetics are applied to the skin, the solid oil crystals break down, causing the encapsulated liquid oil to seep out. The encapsulated liquid oil enables cleansing. However, conventional solid oil-based cleansing cosmetics have the problem that the crystals are difficult to break down, and the rubbing action during use is easily transmitted directly to the skin, causing a strong burden or irritation to the skin.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-136114 [Patent Document 2] Japanese Patent Application Laid-Open No. 2005-194290 [Patent Document 3] Japanese Patent Application Laid-Open No. 2012-206974 [Patent Document 4] Japanese Patent Application Laid-Open No. 2001-213726 Summary of the Invention [Problem to be solved by the invention]
[0005] In view of the above circumstances, an object of the present invention is to provide a solid oil-based cleansing cosmetic that, when used by applying the oil-based cleansing cosmetic directly to the skin, has good hardness in addition to good cleansing power, i.e., good hardness and a good feel on the skin, and also has excellent high-temperature stability. [Means for solving the problem]
[0006] In an embodiment of the present invention, the inventors discovered that an oil-based cleansing cosmetic composition having a specific hardness, which is obtained by combining two types of solid hydrocarbon waxes with different penetration strengths, a specific hydrocarbon oil and ester oil, and a specific nonionic surfactant, has an appropriate hardness when spread on the skin at room temperature, is easy to use, and has excellent high-temperature stability, while also being compatible with makeup cosmetics, has excellent dirt removal properties, and leaves a pleasant feel after cleansing, thereby completing the present invention.
[0007] The present invention relates to an oil-based cleansing cosmetic that contains the following (A), (B), (C), (D), and (E), and has a hardness of 50 to 150 g at 25°C measured with a 3 mmφ pressure-sensitive shaft: (A) 7 to 20 mass% of a solid hydrocarbon wax having a penetration of 6 to 20 at 25°C (B) 1 to 5 mass% of a solid hydrocarbon wax having a penetration of 25 to 50 at 25°C (C) 25% by mass or less of liquid hydrocarbon oil at 25°C (D) Ester oil 50 to 90% by mass (E) 10 to 30% by mass of a nonionic surfactant having an HLB value of 3 to 14
[0008] In the present invention, the mass ratio of component (D) to the total amount of (A) and (B) may be (D) / ((A)+(B))=2.5 to 5, or the mass ratio of (D) to the total amount of (A), (B) and (C) may be (D) / ((A)+(B)+(C))=2.5 to 5.
[0009] In the present invention, the oil-based cleansing cosmetic composition may be in the form of a solid or stick. [Effects of the Invention]
[0010] The oil-based cleansing cosmetic of the present invention has good cleansing power and good hardness, i.e., good hardness and a good feel on the skin, when used by applying the oil-based cleansing cosmetic directly to the skin, and also has excellent high-temperature stability. DETAILED DESCRIPTION OF THE INVENTION
[0011] In this specification, "good cleansing power" means that the product satisfies three criteria: compatibility with makeup, removal of dirt, and rinsability when washed off.
[0012] "Good hardness" means that when an oil-based cleansing cosmetic is spread on the skin under a certain load, it adheres to the skin but does not easily lose its original shape. Specifically, this means that the cosmetic has a hardness of 50 to 150 g measured with a 3 mm diameter pressure-sensitive shaft at 25°C as a physical property, and provides a good feel on the skin as evaluated by a sensory evaluation.
[0013] Furthermore, "high temperature stability" means that the contents will not separate, shrink, crack, become oily (sweating), or undergo other changes in appearance when temperatures are high, such as in summer.
[0014] <Component (A)> The component (A) used in the present invention is a solid hydrocarbon wax having a needle penetration at 25°C of 6 to 20, preferably 7 to 15, and more preferably 7 to 12. Component (A) is used for the purpose of solidifying liquid oil to an appropriate hardness and maintaining the solid form; if the needle penetration is 6 or more, the liquid oil will have good solidification properties, and if it is 20 or less, the solidified liquid oil will ooze out, resulting in a good cleansing effect.
[0015] In the present invention, the penetration rate is determined by measuring the length of time it takes a specified needle (needle mass 2.5±0.02 g, needle holder mass 47.5±0.02 g, weight mass 50±0.05 g) to penetrate a wax sample maintained at 25±0.1°C in 5 seconds, and multiplying this penetration distance (mm) by 10 to obtain the penetration rate, a value measured in accordance with JIS K-2235-5.4 (1991).
[0016] Furthermore, a solid refers to a substance that is in a solid state at 25° C. and has a melting point of 65° C. or higher, preferably 70° C. or higher. Component (A) preferably has a melting point of 65 to 95° C., more preferably 70 to 85° C. If the melting point is 65° C. or higher, the hardness is well maintained, and if the melting point is 95° C. or lower, the compatibility with makeup stains is good.
[0017] In the present invention, the melting point is measured according to Method 3 of the General Testing Methods in the Standards for Cosmetic Ingredients. Specifically, the sample is gradually heated to 90-92°C while stirring until melted, then the heating is stopped and the sample is allowed to cool to a temperature 8-10°C higher than the melting point. Next, after cooling a thermometer (a petrolatum melting point thermometer specified in Japanese Industrial Standards B7410) to 5°C, the water is wiped off with filter paper, and half of the mercury bulb is inserted into the sample, immediately removed, and allowed to cool vertically. When the attached sample becomes cloudy, the sample is immersed in water at a temperature of 16°C or less for 5 minutes. A thermometer is inserted into the test tube and secured with a cork so that there is a 15 mm gap between the bottom of the thermometer and the bottom of the test tube. This test tube is then placed in a 500 mL beaker containing water at approximately 16°C, with the bottom of the test tube secured at a distance of 15 mm from the bottom of the beaker, and heated at a rate of 2°C per minute until the bath temperature reaches 30°C. Heating is then continued at a rate of 1°C per minute, and the temperature is measured when a drop of sample leaves the thermometer. This test is carried out three times, and if the difference in the measurements is less than 1°C, the average is taken; if the difference is 1°C or more, five measurements are taken and the average is used to determine the melting point.
[0018] Examples of solid hydrocarbon waxes having a penetration of 6 to 20 at 25°C as component (A) include mineral waxes such as ozokerite and ceresin, petroleum waxes such as paraffin and petrolatum, and synthetic hydrocarbons such as Fischer-Tropsch wax and polyethylene wax. Of these, ceresin, paraffin, and polyethylene wax are preferred, with paraffin being more preferred.
[0019] These waxes can be commercially available products, and examples thereof include ceresin, such as Ceresin #810 and Ceresin B (both manufactured by Nikko Rica Corporation); paraffin, such as Paraffin Wax 125, 130, 135, 140, 150, 155, HNP-3, 9, SP-0145, 0160, 0165, 1039, 3035, and 3040 (manufactured by Nippon Seiro Co., Ltd.); Fischer-Tropsch wax, such as FT-0070 and 0165 (manufactured by Nippon Seiro Co., Ltd.); and polyethylene wax, such as PERFORMALENE PL POLYETHYLENE, PERFORMALENE 400, and 500 (manufactured by New Phase Technologies).
[0020] The component (A) can be used alone or in combination of two or more. From the viewpoint of good hardness and high-temperature stability, the content is 7 to 20 mass% of the total composition, preferably 8 to 18 mass%, and more preferably 10 to 16 mass%. If the blending amount is 7 mass% or more, the liquid oil in the solid oil crystals does not bleed out and high-temperature stability is good. Furthermore, if the blending amount is 20 mass% or less, the solid oil crystals are easily crumbled, the skin does not feel hard when touched, and uniform application is possible.
[0021] <(B) component> Component (B) is a solid hydrocarbon wax having a needle penetration at 25°C of 25 to 50, preferably 28 to 40. Component (B) is used for the purpose of solidifying liquid oil to an appropriate hardness and maintaining the solid form; if the needle penetration is 25 or more, the liquid oil will have good solidification properties, and if it is 60 or less, the solidified liquid oil will ooze out, resulting in a good cleansing effect.
[0022] By combining component (A) with component (B), which have different penetration strengths, a stronger wax crystal structure is formed, achieving a balance between moldability, storage stability, and coatability.
[0023] Examples of such wax include microcrystalline wax and paraffin wax, with microcrystalline wax being preferred.
[0024] These waxes can be commercially available products, and examples of microcrystalline waxes include Multiwax W-445 (SONNEBORN), Hi-Mic-1045, 1070 (all Nippon Seiro Co., Ltd.), and refined microcrystalline wax (Nikko Rica Co., Ltd.).
[0025] Furthermore, the melting point of component (B) is preferably 65 to 95° C., more preferably 70 to 85° C. If it is 65° C. or higher, the hardness is well maintained, and if it is 95° C. or lower, the compatibility with makeup stains is good.
[0026] The component (B) can be used alone or in combination of two or more. From the viewpoint of good hardness and high-temperature stability, the content is 1 to 5 mass% of the total composition, preferably 1.5 to 4.5 mass%, and more preferably 2 to 4 mass%. If the blending amount is 1 mass% or more, the liquid oil in the solid oil crystals does not bleed out and high-temperature stability is good. On the other hand, if the blending amount is 5 mass% or less, the solid oil crystals easily crumble, the product does not feel hard when touched to the skin, and can be applied evenly.
[0027] <(C) component> The hydrocarbon oil of component (C) used in the present invention is liquid at 25°C. Component (C) is used to improve compatibility with makeup and reduce friction. Examples of such hydrocarbon oils include squalane, liquid paraffin, liquid isoparaffin, heavy liquid isoparaffin, polybutene, hydrogenated polyisobutene, and hydrogenated polydecene, with liquid paraffin, polybutene, and hydrogenated polyisobutene being preferred in terms of ease of application to the skin.
[0028] The component (C) can be used alone or in combination of two or more, and from the viewpoint of ease of application to the skin and compatibility with makeup cosmetics, the content is 25% by mass or less of the total composition, preferably 1 to 20% by mass, and more preferably 1.5 to 15% by mass. If the blending amount is 25% by mass or less, rinsability is good and no sticky feeling is felt after washing.
[0029] <(D) component> The ester oil of component (D) used in the present invention is an ester oil having a viscosity of 100 mPa s or less, preferably 1 to 60 mPa s, at 25° C. Component (D) is used for the purpose of improving compatibility with makeup, and a viscosity of 100 mPa s or less ensures good application to the skin and compatibility with makeup cosmetics.
[0030] In the present invention, the viscosity is measured using a Brookfield rotational viscometer (DV-1, manufactured by Eiko Seiki Co., Ltd.) at 25°C with rotor No. 1 at a rotation speed of 60 rpm for a rotation time of 30 seconds.
[0031] Examples of such ester oils include vegetable oils such as jojoba oil, sunflower oil, linseed oil, and soybean oil; and fatty acid esters such as isopropyl myristate, octyldodecyl myristate, isopropyl isostearate, isononyl isononanoate, butyl stearate, isotridecyl isononanoate, ethylhexyl palmitate, cetyl ethylhexanoate, propylene carbonate, propylene glycol dicaprate, propanediol diisostearate, propanediol di(capric / caprylic), glyceryl tri(caprylic / capric), triethylhexanoin, and trimethylolpropane tri-2-ethylhexanoate. Among these, ethylhexyl palmitate, cetyl ethylhexanoate, and glyceryl tri(caprylic / capric).
[0032] The component (D) can be used alone or in combination of two or more, and from the viewpoints of ease of application to the skin and compatibility with makeup cosmetics, the content is 50 to 90 mass% of the total composition, preferably 50 to 80 mass%, and more preferably 50 to 70 mass%. If the blending amount is 50 mass% or more, compatibility with makeup cosmetics and removal of makeup stains will be good, and if the blending amount is 90 mass% or less, rinsability will be good and no sticky feeling will be felt after washing.
[0033] <(E) component> The nonionic surfactant (E) used in the present invention is intended to improve compatibility between the makeup cosmetic and the cleansing ingredient, and to facilitate washing. From the viewpoint of achieving both compatibility with cosmetics and solubility in water after rinsing, it is desirable to use one or a combination of two or more nonionic surfactants with HLB values of 3 to 14. By combining multiple nonionic surfactants with different HLB values, it is possible to obtain well-balanced performance.
[0034] The nonionic surfactant is not particularly limited, but examples thereof include glycerin fatty acid esters, polyglycerin fatty acid esters, sorbitan fatty acid esters, polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ethers, fatty acid polyoxyethylene glyceryl, polyether-modified silicones, and polyglycerin-modified silicones.
[0035] The "HLB (hydrophile-lipophile balance) value" referred to here was empirically derived by Griffin of Atlas Powder, Inc. in the United States, through emulsification tests using the company's own nonionic surfactants, and a formula has been proposed to express the relationship between this HLB value and the chemical structure of surfactants (see "New Cosmetics Handbook," Nikko Chemicals Co., Ltd., published October 30, 2006).
[0036] Examples of such nonionic surfactants include PEG-20 glyceryl triisostearate (HLB: 8.0), PEG-5 glyceryl triisostearate (HLB: 3.0), PEG-15 glyceryl oleate (HLB: 14.0), PEG-60 hydrogenated castor oil (HLB: 13.5), sorbeth-30 tetraoleate (HLB: 11.5), PEG-15 glyceryl stearate (HLB: 9.5), polyglycerol caprate (HLB: 9.5), (C12-C14) Pareth-3 (HLB: 8.0), etc. Among these, fatty acid polyoxyethylene glyceryl is more preferred, and more particularly, polyoxyethylene glyceryl triisostearate having an ethylene oxide addition mole number of 10 to 30 moles is more preferred.
[0037] From the viewpoint of ease of rinsing, the content of component (E) in the present invention is 10 to 30% by mass of the total composition, preferably 10 to 25% by mass, and more preferably 10 to 20% by mass. If the blending amount is 10% by mass or more, makeup stains are removed well, and if the blending amount is 30% by mass or less, no burden or irritation is felt on the skin.
[0038] The oil-based cleansing cosmetic of the present invention has a hardness of 50 to 150 g, more preferably 70 to 140 g, measured with a 3 mm diameter pressure-sensitive shaft at 25° C. Within this range, the cosmetic has a good feel on the skin at room temperature, excellent spreadability, little strain on the skin, and good high-temperature stability.
[0039] In the present invention, "hardness" refers to the breaking load, expressed in grams, applied to a pressure-sensitive shaft when the diameter of the pressure-sensitive shaft is 3 mm and the sample stage is raised at a rate of 0.36 cm / sec at 25°C using a Card Meter Max ME-305 manufactured by I-Techno Co., Ltd.
[0040] In the present invention, the mass ratio (D) / ((A)+(B)) of component (D) to the total amount of components (A) and (B) is preferably 2.5 to 5, and more preferably 2.5 to 4.8, from the viewpoints of ease of application to the skin, ease of blending with makeup cosmetics, and ease of rinsing.
[0041] In the present invention, the mass ratio (D) / ((A)+(B)+(C)) of component (D) to the total amount of components (A), (B), and (C) is preferably 2.5 to 5, and more preferably 2.5 to 4.5, from the viewpoints of ease of application to the skin, ease of blending with makeup cosmetics, and ease of rinsing.
[0042] The oil-based cleansing cosmetic of the present invention is a cleansing cosmetic that does not have fluidity at room temperature (25°C) and normal pressure (1 atmosphere), and its shape may be a rod, a plate, or one that is poured into a container. However, from the viewpoint of ease of use, good moldability, and good spreadability, it is preferable that the oil-based cleansing cosmetic be filled into a stick container or the like and used by applying it directly to the skin without staining the hands.
[0043] Furthermore, oily means that the cosmetic does not substantially contain water, and the water content relative to the total amount of the cosmetic is preferably less than 3% by mass, more preferably less than 2% by mass, and even more preferably less than 1% by mass.
[0044] The oil-based cleansing cosmetic of the present invention may further contain an oil-based gelling agent, as long as the effect of the present invention is not impaired. Examples of oil-based gelling agents include those used in ordinary cosmetics, such as metal soaps, organically modified clay minerals, and dextrin fatty acid esters.
[0045] In addition to the essential ingredients described above, the oil-based cleansing cosmetic of the present invention may contain, within the scope of the object of the present invention, powders, oil thickeners other than those described above, moisturizers, plant extracts, vitamins, antioxidants, preservatives, disinfectants, UV absorbers, anti-inflammatory agents, insect repellents, physiologically active ingredients, fragrances, essential oils, etc. Note that these agents are not limited to their individual uses, and may be used for other purposes depending on the purpose, for example, vitamins may be used as antioxidants, or may be used in combination with other uses, for example, to exert the effects of both insect repellents and fragrances.
[0046] Examples of the physiologically active ingredient include substances that impart some kind of physiological activity to the skin when applied to the skin. Examples include anti-inflammatory agents, anti-aging agents, UV protection agents, tightening agents, antioxidants, moisturizing agents, blood circulation promoters, antibacterial agents, disinfectants, drying agents, cooling agents, warming agents, vitamins, amino acids, wound healing promoters, irritation alleviators, analgesics, cell activators, enzyme components, etc. Examples of the physiologically active ingredient include natural plant extracts, seaweed extracts, herbal ingredients, and compounds, and among these, natural plant extracts, seaweed extracts, and herbal ingredients are particularly preferred in terms of safety.
[0047] In addition to the above-mentioned natural plant extracts, seaweed extracts, and herbal ingredients, other ingredients include, for example, biopolymers such as deoxyribonucleic acid, mucopolysaccharides, sodium hyaluronate, sodium chondroitin sulfate, collagen, elastin, chitin, chitosan, and hydrolyzed eggshell membrane; moisturizing ingredients such as amino acids, sodium lactate, urea, sodium pyrrolidone carboxylate, betaine, and whey; oily ingredients such as sphingolipids, ceramides, cholesterol, cholesterol derivatives, and phospholipids; anti-inflammatory agents such as ε-aminocaproic acid, glycyrrhizic acid, β-glycyrrhetinic acid, lysozyme chloride, guaiazulene, and hydrocortisone; vitamins (A, B2, B6, C, D, E), vitamins such as calcium pantothenate, biotin, nicotinamide, vitamin C ester, active ingredients such as allantoin, diisopropylamine dichloroacetate, 4-aminomethylcyclohexanecarboxylic acid, antioxidants such as tocopherol, carotenoids, flavonoids, tannins, lignans, saponin, cell activators such as α-hydroxy acids and β-hydroxy acids, blood circulation promoters such as γ-oryzanol and vitamin E derivatives, disinfectants such as isopropylmethylphenol, triclosan, hinokitiol, and benzalkonium chloride, cooling agents such as l-menthol and peppermint oil, and wound healing agents such as retinol and retinol derivatives.
[0048] The oil-based cleansing cosmetic of the present invention can be suitably used as a cleansing cosmetic for the skin, and can be used by applying it to the scalp, face, body, hands, feet, etc., rubbing it in to absorb dirt, and then wiping it off or rinsing with water. [Example]
[0049] Examples 1 to 4 and Comparative Examples 1 to 14 An oil-based cleansing cosmetic was prepared with the composition shown in Table 1, and its hardness was measured, and its high-temperature stability, compatibility with makeup cosmetics, makeup removal, and rinsing properties were evaluated. The results are also shown in Table 1. The present invention will be further explained with reference to examples, but the present invention is not limited to these examples in any way.
[0050] (Manufacturing method) All of the ingredients shown in Table 1 were heated to 100°C to dissolve and mix uniformly to obtain a bulk oil-based cleansing cosmetic.
