Depending on the desired texture of use, the oil-based solid cleansing cosmetic of the present invention may additionally include ingredients other than the essential ingredients Ingredients A to F. Each of the above ingredients Ingredients A to F and other ingredients included in the oil-based solid cleansing cosmetic of the present invention may use only one type or two or more types.

[0019] The oily solid cleansing cosmetic of the present invention is characterized by excellent makeup removal performance, as it is solid at room temperature, does not run off during use, and is an oily cleansing cosmetic with solid oil, liquid oil, and nonionic surfactant as main components. In addition, the oily solid cleansing cosmetic of the present invention is characterized by excellent dispersion of charcoal powder without aggregation or sedimentation, as it contains a predetermined amount of charcoal powder, the amounts of component A and component B are within a predetermined range, and a predetermined amount of component C and component F are added.

[0020] Below, ingredients A to F, which are essential components of the oily solid cleansing cosmetic of the present invention, will be described.

[0021] [Ingredient A]

[0022] Component A is a solid oil that is solid at 25°C and has a melting point of 50 to 120°C. In addition, in this specification, "solid at 25°C" means a state that is non-fluid at 25°C. Also, the melting point of Component A can be measured by the second melting point measurement method, which is a general test method of the raw material specifications for quasi-drugs.

[0023] The melting point of component A is 50°C or higher, preferably 55°C or higher, and more preferably 60°C or higher, from the perspective of moldability (the ability to form a uniform solid shape during preparation) and stability over time. In addition, the melting point of component A is 120°C or lower, preferably 115°C or lower, and more preferably 110°C or lower, from the perspective of dispensing with fingers and the feel (usage sensation) when applied.

In addition, if the content is 90 mass% or less, the moldability is excellent. The content of component B is the sum of the contents of all component B in the oily solid cleansing cosmetic of the present invention.

[0040] [Ingredient C]

[0041] Ingredient 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 oily solid cleansing cosmetics, there is a problem in that it is difficult to rinse off with water or lukewarm water after cleansing because of the low affinity with 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 oily solid cleansing cosmetics is generally avoided. However, by using a specific amount of Ingredient C and water in combination with charcoal powder, the above-mentioned problem can be avoided, and the aggregation and sedimentation of the charcoal powder can also be suppressed.

[0042] The HLB value of component C is 2 to 6, preferably 2 to 5, and more preferably 2 to 4. By having the HLB value within the above range, the aggregation and sedimentation of the charcoal powder can be effectively suppressed.

[0043] As for component C, it 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 triisostearisate, hydrogenated castor oil PEG-20 triisostearisate, PEG-5 triisostearisate, glyceryl monostearate, diglyceryl monostearate, decaglyceryl pentastearate, sorbitan sesquistearisate, and sorbitan monooleate. Among these, polyglyceryl-2 triisostearisate is preferred because it can suppress the aggregation and sedimentation of charcoal powder without impairing the user experience, such as a residue feeling when rinsing.

[0044] The content of component C in the oily solid cleansing cosmetic of the present invention is 0.01 to 5.0 mass%, preferably 0.01 to 4.0 mass%. If the content is 0.01 mass% or more, the aggregation and sedimentation of charcoal powder can be suppressed. In addition, if the content is 5.0 mass% or less, the aggregation and sedimentation of charcoal powder can be suppressed without compromising the residue sensation upon rinsing. The content of component C is the sum of the contents of all components C in the oily solid cleansing cosmetic of the present invention.

[0045] [Ingredient D]

[0046] Ingredient D is a nonionic surfactant with an HLB value of 8 to 15. By using Ingredient D, an oily solid cleansing cosmetic can be produced that has excellent makeup affinity during use and leaves a low residue when rinsed off. In addition, the HLB value in this specification can be calculated by the Griffin method.

[0047] The HLB value of ingredient D is 8 to 15, preferably 8 to 14, and more preferably 8 to 13. Since the HLB value is within the above range, the affinity for makeup and washability during use are excellent.

[0048] As for component D, it is not particularly limited to nonionic surfactants having an HLB value of 8 to 15, but may 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 wax derivatives, sugar esters, polyoxyethylene hardened castor oil, polyoxyethylene castor oil, etc.

[0049] Ingredient D preferably contains polyglycerin fatty acid esters from the perspective that it has excellent makeup compatibility during use and provides a firm skin texture after rinsing. Examples of polyglycerin fatty acid esters include polyglyceryl-6 dicapric acid, polyglyceryl-10 dioleic acid, polyglyceryl-6 caprylic acid, and polyglyceryl-2 capric acid.

[0050] The content of component D in the oily solid cleansing cosmetic of the present invention is 8 to 22 mass%, preferably 9 to 21 mass%, and more preferably 10 to 20 mass%. If the content is 8 mass% or more, the affinity for makeup during use is excellent. Also, if the content is 22 mass% or less, the washability is excellent.

[0051] In addition, when polyglycerin fatty acid ester is contained as component D, the content of polyglycerin fatty acid ester in the oily solid cleansing cosmetic of the present invention is preferably 0.1 to 6.0 mass%, and more preferably 0.5 to 4.0 mass%. If the above content is 0.1 mass% or more, a firm skin sensation after use is obtained on the skin after rinsing. In addition, if the above content is 6.0 mass% or less, the rinsing ability is superior.

[0052] [Ingredient E]

[0053] Ingredient E is charcoal powder having a median diameter based on a predetermined volume (hereinafter also referred to simply as the median diameter). By using Ingredient E, the charcoal powder adsorbs makeup contaminants and sebum contaminants, resulting in an oily solid cleansing cosmetic with superior cleansing power. Although there is a problem in the formulation process of the oily solid cleansing cosmetic where the charcoal powder aggregates and settles, causing the composition to become non-uniform, by using a predetermined amount of Ingredient C and water together, aggregation and settling are suppressed, making it possible to produce an oily solid cleansing cosmetic with excellent dispersibility of the charcoal powder.

[0054] Component E is not particularly limited but is a porous carbon material and may contain hydrogen, oxygen, inorganic components, etc., in addition to carbon. Furthermore, it is preferable that it be activated carbon having fine pores, produced by reacting a carbon material with a gas or chemical at high temperatures.

[0055] The raw material for component E is not particularly limited and can be any material generally used as a raw material for charcoal powder. 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.

[0056] The median diameter of ingredient E is 1 μm or more in terms of cleansing power, and preferably 3 μm or more. In addition, the median diameter of ingredient E is 35 μm or less in terms of inhibition of aggregation and sedimentation and residual feeling after rinsing, and preferably 32 μm or less.

[0057] In the present specification, the median diameter of the charcoal powder based on volume can be measured by a laser analysis / scattering particle diameter distribution measurement method, and can be a value measured, for example, by a “particle size distribution meter LA-950V2” (manufactured by Horiba Seisakusho).

[0058] The content of component E in the oily solid cleansing cosmetic of the present invention is 0.01 to 5.0 mass%, preferably 0.02 to 4.0 mass%, and more preferably 0.03 to 3.5 mass%. If the above content is 0.01 mass% or more, the effect of incorporating charcoal powder is obtained. In addition, if the above content is 5.0 mass% or less, the rinseability is excellent, and the aggregation and sedimentation of component E can be suppressed. The above content of component E is the sum of the contents of all component E in the oily solid cleansing cosmetic of the present invention.

[0059] [Ingredient F]

[0060] Component F is water, and while not specifically limited, purified water is preferred. Oily solid cleansing cosmetics are generally composed of solid oil, liquid oil, and nonionic surfactants as main components, and it is common for them not to contain water due to concerns about separation or precipitation. However, by using a predetermined amount of component C and component E in combination, the aggregation and sedimentation of component E can be suppressed, thereby making it an oily solid cleansing cosmetic with excellent dispersibility of charcoal powder.

[0061] The content of component F in the oily solid cleansing cosmetic of the present invention is 0.5 to 6.0 mass%, preferably 0.6 to 5.5 mass%, and more preferably 0.8 to 4.0 mass%. If the above content is 0.5 mass% or more, the aggregation and sedimentation of component E can be suppressed. In addition, if the above content is 6.0 mass% or less, the affinity for makeup during use is excellent. The content of component F is the sum of the contents of all components F in the oily solid cleansing cosmetic of the present invention.

[0062] [Other ingredients]

[0063] The oily solid cleansing cosmetic of the present invention may contain, in addition to ingredients A to F, other ingredients as optional ingredients within a range that does not impair the effects of the present invention.

[0064] Other ingredients include surfactants other than ingredients C and D, powders other than ingredient E, dyes, oily gelling agents, oil-soluble resins, polyhydric alcohols, lower alcohols, whitening agents, revitalizers, blood circulation promoters, anti-seborrheic agents, anti-inflammatory agents, cooling agents (also known as cooling agents), antibacterial ingredients, antiperspirant ingredients, ultraviolet absorbers, ultraviolet scattering agents, moisturizers, fragrances, antioxidants, preservatives, antifoaming agents, and additives such as various extracts.

[0065] [Oil-based solid cleansing cosmetic]

[0066] The oil-based solid cleansing cosmetic of the present invention is in a solid state at 25°C. The term "solid state" means that it does not have fluidity, and includes paste-like or gel-like forms. Furthermore, the form of the oil-based solid cleansing cosmetic of the present invention is not particularly limited, and examples include those formed by pouring into containers such as sticks, rods, plates, or jars.

[0067] The method for manufacturing the oil-based solid cleansing cosmetic of the present invention is not particularly limited and may employ a known method for manufacturing an oil-based solid cleansing cosmetic.
