Summary of the Invention

[0006] Oil-based solid cleansing cosmetics are prepared by melting and solidifying the aforementioned main component and other components. Therefore, when components that have properties of agglomeration and sedimentation, such as charcoal powder, are incorporated, agglomeration and sedimentation tend to occur before solidification, resulting in a problem of an uneven composition.

[0007] The object of the present invention is to provide an oily solid cleansing cosmetic composition that, despite containing charcoal powder, exhibits excellent dispersibility of charcoal powder without aggregation or sedimentation of the charcoal powder. [Means for solving the problem]

[0008] As a result of diligent research to solve the above problems, the inventors of the present invention have found that by creating an oily solid cleansing cosmetic composition containing solid oil, liquid oil, a nonionic surfactant with an HLB value of 2 to 6, a nonionic surfactant with an HLB value of 8 to 15, a predetermined charcoal powder, and water, an oily solid cleansing cosmetic composition with excellent uniformity can be obtained without the charcoal powder agglomerating or settling, thus completing the present invention.

[0009] In other words, the present invention relates to an oily solid cleansing cosmetic composition containing 4.0 to 20% by mass of component A, 50 to 90% by mass of component B, 0.01 to 5.0% by mass of component C, 8 to 22% by mass of component D, 0.01 to 5.0% by mass of component E, and 0.5 to 6.0% by mass of component F. Component A: Solid oil with a melting point of 50-120°C Ingredient B: Liquid oil Component C: Nonionic surfactant with an HLB value of 2-6 Component D: Nonionic surfactant with an HLB value of 8-15 Component E: Carbon powder with a median diameter of 1-35 μm by volume. Ingredient F: Water [Effects of the Invention]

[0010] The oil-based solid cleansing cosmetic of the present invention, despite containing charcoal powder, exhibits excellent dispersibility of charcoal powder without aggregation or sedimentation. [Modes for carrying out the invention]

[0011] The oil-based solid cleansing cosmetic composition of the present invention is characterized by containing predetermined amounts of a solid oil (component A) having a melting point of 50 to 120°C, a liquid oil (component B), a nonionic surfactant (component C) with an HLB value of 2 or more and less than 6, a nonionic surfactant (component D) with an HLB value of 8 to 15, charcoal powder (component E) with a volume-based median diameter of 1 to 35 μm, and water (component F).

[0012] In other words, the oil-based solid cleansing cosmetic composition of the present invention contains at least component A, component B, component C, component D, component E, and component F. Depending on the desired feel and other factors, the oil-based solid cleansing cosmetic composition of the present invention may further contain components other than the essential components A to F. Each of the components A to F and other components contained in the oil-based solid cleansing cosmetic composition of the present invention may be used individually or in combination of two or more.

[0013] The oil-based solid cleansing cosmetic of the present invention is solid at room temperature, so it does not drip during use, and because it is an oil-based cleansing cosmetic mainly composed of solid oil, liquid oil, and a nonionic surfactant, it has the characteristic of having excellent makeup removal performance. Furthermore, the oil-based solid cleansing cosmetic of the present invention contains a predetermined amount of charcoal powder, the amounts of components A and B are within a predetermined range, and predetermined amounts of components C and F are also included, so despite containing charcoal powder, the charcoal powder does not aggregate or settle, and the charcoal powder has the characteristic of having excellent dispersibility.

[0014] The essential components A to F of the oil-based solid cleansing cosmetic composition of the present invention are described below.

[0015] [Component A] Component A is solid at 25°C and is a solid oil with a melting point of 50 to 120°C. In this specification, "solid at 25°C" means a property without fluidity at 25°C. Also, the melting point of Component A can be measured by the second method of the melting point measurement method, which is a general test method for quasi-drugs raw material specifications.

[0016] From the viewpoints of moldability, which can be molded into a uniform solid shape during preparation, and stability over time, the melting point of Component A is 50°C or higher, preferably 55°C or higher, more preferably 60°C or higher. Also, from the viewpoints of finger pickability during use and the feel during application (usability), the melting point of Component A is 120°C or lower, preferably 115°C or lower, more preferably 110°C or lower.

[0017] Examples of Component A include wax esters such as animal and plant waxes, mineral waxes, and hydrocarbon waxes.

[0018] Examples of the above animal and plant waxes include carnauba wax, sunflower seed wax, candelilla wax, beeswax, shellac wax, rice wax, rice bran wax, shellac wax, and spermaceti wax.

[0019] Examples of the above mineral waxes include montan wax.

[0020] The above hydrocarbon wax may be a petroleum-derived wax or a synthetic wax. Examples of the above hydrocarbon waxes include, for example, ceresin, ozokerite, paraffin wax, microcrystalline wax, polyethylene wax, ethylene-propylene copolymer, and Fischer-Tropsch wax (synthetic wax).

[0021] From the viewpoint of obtaining a uniform oily solid cleansing cosmetic that is less likely to oxidize during heating, hydrocarbon wax is preferred as Component A, and microcrystalline wax and Fischer-Tropsch wax (synthetic wax) are more preferred.

[0022] The content of component A in the oil-based solid cleansing cosmetic of the present invention is 4.0 to 20% by mass, preferably 4.2 to 18% by mass, and more preferably 4.4 to 16% by mass. When the above content is 4.0% by mass or more, the moldability is excellent, and the effect of suppressing the aggregation and sedimentation of carbon powder is excellent. Further, when the above content is 20% by mass or less, the usability is excellent, and the disintegration during transportation or the like caused by excessive hardening can be suppressed. The content of the above component A is the total content of all component A in the oil-based solid cleansing cosmetic of the present invention.

[0023] [Component B] Component B is a liquid oil and includes an oil component having a fluid property at 25°C, a semi-solid oil component having a melting point of less than 50°C, and a volatile oil component having a boiling point of less than 260°C.

[0030] Examples of the above-mentioned higher alcohols include lauryl alcohol, oleyl alcohol, isostearyl alcohol, octyldodecanol, and jojoba alcohol.

[0031] The content of component B in the oil-based solid cleansing cosmetic of the present invention is 50 to 90% by mass, preferably 60 to 88% by mass, and more preferably 70 to 86% by mass. When the above content is 50% by mass or more, it is excellent in terms of how easily it comes off with fingers during use and how easily it spreads and blends during application. When the above content is 90% by mass or less, it is excellent in terms of moldability. The above content of component B is the total content of all component B in the oil-based solid cleansing cosmetic of the present invention.

[0032] [Component C] Component C is a nonionic surfactant with an HLB value of 2 to 6. Nonionic surfactants with an HLB value of 6 or less are nonionic surfactants with low hydrophilicity and high lipophilicity. When such nonionic surfactants are incorporated into oil-based solid cleansing cosmetics, even when trying to wash them off with water or lukewarm water after cleansing, they are difficult to rinse off due to their low affinity for water, and it takes time for the slippery feeling of the cleansing cosmetic to disappear. For this reason, the incorporation of nonionic surfactants with low HLB values ​​into oil-based solid cleansing cosmetics is generally avoided. However, by using a specific amount of component C and water in combination with charcoal powder, the above problems can be avoided, and the aggregation and sedimentation of the charcoal powder can be suppressed.

[0033] The HLB value of component C is 2 to 6, preferably 2 to 5, and more preferably 2 to 4. By having the above HLB value within this range, aggregation and sedimentation of the charcoal powder can be effectively suppressed.

[0034] Component C is not particularly limited as long as it is a nonionic surfactant with an HLB value of 2 to 6, but examples include polyglyceryl-2 triisostearate, PEG-20 hydrogenated castor oil triisostearate, PEG-5 glyceryl triisostearate, glyceryl monostearate, diglyceryl monostearate, decaglyceryl pentastearate, sorbitan sesquistearate, and sorbitan monooleate. Among these, polyglyceryl-2 triisostearate is preferred because it can suppress the aggregation and sedimentation of charcoal powder without impairing the user experience, such as the feeling of residue after rinsing.

[0035] The content of component C in the oil-based solid cleansing cosmetic of the present invention is 0.01 to 5.0% by mass, preferably 0.01 to 4.0% by mass. When the above content is 0.01% by mass or more, aggregation and sedimentation of charcoal powder can be suppressed. Furthermore, when the above content is 5.0% by mass or less, aggregation and sedimentation of charcoal powder can be suppressed without impairing the feeling of residue when rinsing. The above content of component C is the total content of all component C in the oil-based solid cleansing cosmetic of the present invention.

[0036] [Component D] Component D is a nonionic surfactant with an HLB value of 8-15. By using component D, it is possible to create an oil-based solid cleansing cosmetic that blends well with makeup during use and leaves little residue after rinsing. The HLB value in this specification can be calculated using the Griffin method.

[0037] The HLB value of component D is 8 to 15, preferably 8 to 14, and more preferably 8 to 13. Having the above HLB value within this range results in excellent makeup blendability and washability during use.

[0038] Component D is not particularly limited as long as it is a nonionic surfactant with an HLB value of 8 to 15, but examples include polyglycerin fatty acid esters, sorbitan fatty acid esters, monoglycerin fatty acid esters and their alkylene oxide adducts, polyoxyalkylene alkyl ethers, polyoxyalkylene fatty acid esters, polyoxyalkylene alkylphenols, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene alkylphenyl formaldehyde condensates, polyoxyethylene sterols and their derivatives, polyoxyethylene lanolin and its derivatives, polyoxyethylene beeswax derivatives, sugar esters, polyoxyethylene hydrogenated castor oil, and polyoxyethylene castor oil.

[0039] Ingredient D preferably contains a polyglycerin fatty acid ester, as it provides excellent makeup blendability during use and leaves the skin feeling supple after rinsing. Examples of polyglycerin fatty acid esters include polyglyceryl-6 dicaprate, polyglyceryl-10 dioleate, polyglyceryl-6 caprylate, and polyglyceryl-2 caprate.

[0040] The content of component D in the oil-based solid cleansing cosmetic of the present invention is 8 to 22% by mass, preferably 9 to 21% by mass, and more preferably 10 to 20% by mass. When the above content is 8% by mass or more, it blends well with makeup during use. When the above content is 22% by mass or less, it rinses off well.

[0041] Furthermore, when polyglycerin fatty acid ester is included as component D, the content of polyglycerin fatty acid ester in the oily solid cleansing cosmetic composition of the present invention is preferably 0.1 to 6.0% by mass, and more preferably 0.5 to 4.0% by mass. When the above content is 0.1% by mass or more, a moist and supple after-skin feeling is obtained after rinsing. When the above content is 6.0% by mass or less, the rinseability is even better.

[0042] [Component E] Component E is charcoal powder having a predetermined volume-based median diameter (hereinafter also simply referred to as median diameter). By using component E, the charcoal powder adsorbs makeup and sebum, resulting in an oil-based solid cleansing cosmetic with superior cleansing power. In the preparation process of oil-based solid cleansing cosmetics, there is a problem that the charcoal powder aggregates and settles, resulting in an uneven composition. However, by using it in combination with a predetermined amount of component C and water, aggregation and settling can be suppressed, and an oil-based solid cleansing cosmetic with excellent dispersibility of charcoal powder can be obtained.

[0043] Component E is not particularly limited, but is a porous carbon material and may contain hydrogen, oxygen, inorganic components, etc., in addition to carbon. Preferably, it is activated carbon with fine pores, produced by reacting a carbon material with gas or chemicals at high temperatures.

[0044] The raw materials for component E are not particularly limited, and those commonly used as raw materials for charcoal powder can be used. Specifically, examples include coconut shells, bamboo, wood, sawdust, coal, phenolic resin, rayon, acrylonitrile, coal pitch, petroleum pitch, etc. Among these, coconut shells, bamboo, and wood are preferred.

[0045] The median diameter of component E is 1 μm or more, preferably 3 μm or more, from the viewpoint of cleansing power. Furthermore, the median diameter of component E is 35 μm or less, preferably 32 μm or less, from the viewpoint of suppressing aggregation and sedimentation and the feeling of residue after rinsing.

[0046] In this specification, the volume-based median diameter of the charcoal powder can be measured by laser analysis / scattering particle size distribution measurement, and can be the value measured by, for example, a "Particle Size Distribution Meter LA-950V2" (manufactured by Horiba, Ltd.).

[0047] The content of component E in the oil-based solid cleansing cosmetic of the present invention is 0.01 to 5.0% by mass, preferably 0.02 to 4.0% by mass, and more preferably 0.03 to 3.5% by mass. When the above content is 0.01% by mass or more, the effects of incorporating charcoal powder can be obtained. Furthermore, when the above content is 5.0% by mass or less, excellent rinseability is achieved, and aggregation and sedimentation of component E can be suppressed. The above content of component E is the total content of all components E in the oil-based solid cleansing cosmetic of the present invention.

[0048] [Component F] Component F is water, and is not particularly limited, but purified water is preferred. Oily solid cleansing cosmetics generally do not contain water because they mainly consist of solid oil, liquid oil, and nonionic surfactants, and there is a risk of separation and precipitation. However, by using it in combination with predetermined amounts of components C and E, it is possible to suppress the aggregation and sedimentation of component E and to produce an oily solid cleansing cosmetic with excellent dispersibility of charcoal powder.

[0049] The content of component F in the oil-based solid cleansing cosmetic of the present invention is 0.5 to 6.0% by mass, preferably 0.6 to 5.5% by mass, and more preferably 0.8 to 4.0% by mass. When the above content is 0.5% by mass or more, aggregation and sedimentation of component E can be suppressed. Furthermore, when the above content is 6.0% by mass or less, excellent makeup blending is achieved during use. The above content of component F is the total content of all component F in the oil-based solid cleansing cosmetic of the present invention.

[0050] [Other ingredients] In addition to components A to F, the oil-based solid cleansing cosmetic composition of the present invention may contain other components as optional components, provided that they do not impair the effects of the present invention.

[0051] Other ingredients include surfactants other than components C and D, powders other than component E, dyes, oily gelling agents, oil-soluble resins, polyhydric alcohols, lower alcohols, whitening agents, activators, blood circulation promoters, anti-seborrheic agents, anti-inflammatory agents, cooling agents (also known as chilling agents), antibacterial agents, antiperspirant agents, UV absorbers, UV scattering agents, moisturizers, fragrances, antioxidants, preservatives, defoaming agents, and various extracts.

[0052] [Oil-based solid cleansing cosmetic] The oil-based solid cleansing cosmetic of the present invention is solid at 25°C. The term "solid" means that it does not have fluidity, and includes paste and gel forms. Furthermore, the shape of the oil-based solid cleansing cosmetic of the present invention is not particularly limited and may include stick, rod, plate, or molded form in containers such as jars.

[0053] The method for producing the oil-based solid cleansing cosmetic of the present invention is not particularly limited, and known methods for producing oil-based solid cleansing cosmetics can be employed. Examples of methods for producing the oil-based solid cleansing cosmetic of the present invention include mixing each component while heating to obtain a mixture, and then cooling and solidifying the obtained mixture.
