Description

Technical Field

[0001] The present invention relates to a semi-solid temperature-sensitive cleansing cosmetic.

Background Art

[0002] Cleansing cosmetics for removing makeup stains and sebum stains are roughly classified into aqueous cleansing cosmetics called water cleansing and oily cleansing cosmetics called oil cleansing. Among cleansing cosmetics, oily cleansing cosmetics contain a large amount of oil agents, so they blend well with makeup stains and can exhibit excellent cleansing power. On the other hand, they have the drawback that a sticky feeling peculiar to oil remains on the skin after cleansing, resulting in a poor feeling of use. However, it can be said that oily cleansing cosmetics are attractive products for those who want to thoroughly remove makeup stains.

[0003] In recent years, as a form of oily cleansing cosmetics, semi-solid cleansing cosmetics called cleansing balms have attracted attention. Cleansing balms have the characteristic that they blend very well with makeup stains and can exhibit an extremely excellent cleansing effect. In addition, the solidified oil agent becomes soft on the skin during use and gives a unique feeling of melting. Such functions and feelings of use are the reasons for their popularity. Therefore, in recent years, the development of these semi-solid cleansing cosmetics has been actively carried out.

[0004] ]> Specifically, proposed examples include oily solid cleansing materials containing a solid oil, a liquid oil, and a nonionic surfactant having a specific melting point (see, for example, Patent Document 1); solid oily cleansing cosmetics containing a specific amount of hydrocarbon oil having a specific melting point, a specific amount of ester oil, and a specific amount of nonionic surfactant having a specific HLB value (see, for example, Patent Document 2); and oily solid cleansing cosmetics containing a specific amount of solid oil having a specific melting point, a specific amount of liquid oil, a specific amount of nonionic surfactant having a specific HLB value, a specific amount of powder with a specific particle size, and a specific amount of fuzzy silica (see, for example, Patent Document 3).

[0005] However, even conventional semi-solid cleansing cosmetics, which blend well with makeup and exhibit excellent makeup removal effects, have the drawback of not being able to sufficiently remove sebum and makeup residue clogged in pores. Furthermore, while it is possible to adsorb and remove dirt to some extent by using powders, these attempts have not yet been able to fully achieve the effect of removing dirt clogged deep in pores. In addition, depending on the type and size of the powder used, there are problems such as adverse effects on the stability of the formulation and the melting texture characteristic of balms, so ingenuity was required in formulation.

[0014] The semi-solid, warming cleansing cosmetic composition of the present invention, by satisfying the above constituent requirements, possesses excellent formulation stability. Furthermore, because it provides a unique melting sensation and a thick texture when spread, it blends very well with sebum and makeup residue, resulting in a remarkably superior cleansing effect (dirt removal effect).

[0015] Furthermore, the semi-solid, warming cleansing cosmetic of the present invention provides a sufficient, optimal warming sensation during cleansing, which allows it to open pores and lift and remove (dissolve and / or adsorb) sebum and makeup residue that is clogged deep within the pores. [Modes for carrying out the invention]

[0016] The semi-solid, warming cleansing cosmetic composition of the present invention contains: component A: a wax and / or hydrocarbon oil that is solid at room temperature; component B: one or more ester oils selected from monoester oils, diester oils, and triester oils; component C: a nonionic surfactant; and component D: zeolite.

[0017] In this specification, "semi-solid form" refers to a solid dosage form that is non-fluid and deforms under stress such as pressure from a finger. Furthermore, "non-fluid" means a state in which, when a cosmetic is filled into a wide-mouthed container and the container is tilted at a 45-degree angle for 30 seconds, the cosmetic does not drip out of the wide-mouthed container.

[0018] The following describes the details of each component used in the semi-solid, warming cleansing cosmetic of the present invention.

[0019] [Component A] Component A above is a wax that is solid at room temperature and / or a hydrocarbon oil that is solid at room temperature. That is, Component A above is one or both of a wax that is solid at room temperature and a hydrocarbon oil that is solid at room temperature. In the present invention, by using Component A above, the cleansing cosmetic of the present invention can be made into a semi-solid form with excellent formulation stability. Further, by combining with Component B described later, it can exhibit a unique feeling of use that melts during spreading and a thick feeling of use, and can improve the compatibility with sebum dirt and makeup dirt.

[0020] In addition, in this specification, "solid at room temperature" refers to a property without fluidity in the temperature range of 1 to 30°C. Further, in this specification, the wax that is solid at room temperature may be referred to as "Component A1", and the hydrocarbon oil that is solid at room temperature may be referred to as "Component A2".

[0021] Specific examples of Component A1 include carnauba wax, candelilla wax, beeswax, rice bran wax, shellac wax, whale wax, lanolin, and the like. These Component A1 may be used alone or in appropriate combination of two or more.

[0022] Specific examples of Component A2 include ceresin, paraffin wax, Fischer-Tropsch wax (synthetic wax), microcrystalline wax, polyethylene wax, polyethylene powder, petrolatum, and the like. These Component A2 may be used alone or in appropriate combination of two or more.

[0023] Among the above Component A, from the viewpoints of being able to be made into a semi-solid form with excellent formulation stability, exhibiting a unique feeling of use during spreading, and improving the compatibility with dirt such as makeup, it is preferable to use at least Component A2. In the present invention, among these Component A2, it is more preferable to use Fischer-Tropsch wax (synthetic wax), polyethylene wax, and polyethylene powder, and it is most preferable to use Fischer-Tropsch wax (synthetic wax).

[0024] In this invention, component A can be a commercially available product. The commercially available component A is not particularly limited, whether it is a single raw material or a mixed raw material with other components, as long as the desired effect is achieved.

[0025] The content of component A in the semi-solid warming cleansing cosmetic of the present invention is not particularly limited as long as the desired effect is sufficiently achieved. However, from the viewpoint of achieving a semi-solid form with excellent formulation stability, as well as from the viewpoint of the feel when applied and compatibility with dirt, it is preferably 2% by mass or more, and more preferably 3% by mass or more, of 100% by mass of the cosmetic. Furthermore, from the viewpoint of suppressing deterioration of the feel due to the formulation becoming too hard, it is preferably 8% by mass or less, and more preferably 7% by mass or less, of 100% by mass of the cosmetic. Note that the above content of component A is the amount converted to pure content.

[0026] [Component B] The above component B is one or more ester oils selected from monoester oils, diester oils, and triester oils. In the present invention, by using the above component B, it is possible to improve compatibility with sebum and makeup dirt and exhibit a remarkably superior cleansing effect (dirt removal effect). In the present invention, it is preferable to use an ester oil that is liquid at room temperature, which allows these effects to be exerted to the fullest extent. In this specification, "liquid at room temperature" means a state in which it is fluid in a temperature range of 1 to 30°C.

[0027] Furthermore, in order to provide a unique melting and thick texture when spread, and to impart a remarkably superior cleansing effect, component B preferably contains any of monoester oil, diester oil, and triester oil, and is composed of these three types of ester oils. In the present invention, among the preferred components B, it is most preferable to use monoester oil, diester oil, and triester oil that are liquid at room temperature.

[0028] In this specification, the monoester oil that is liquid at room temperature may be referred to as "component B1," the diester oil that is liquid at room temperature may be referred to as "component B2," and the triester oil that is liquid at room temperature may be referred to as "component B3."

[0029] Specific component B1 includes, for example, monoester oils of linear fatty acids and lower alcohols such as isopropyl myristate, butyl myristate, isopropyl palmitate, ethyl oleate, ethyl linoleate, and isopropyl linoleate; monoester oils of linear fatty acids and linear higher alcohols such as cetyl caprylate, hexyl laurate, decyl myristate, decyl oleate, and oleyl oleate; propylheptyl caprylate, isostearyl laurate, isotridecyl myristate, isocetyl myristate, isostearyl myristate, octyldodecyl myristate, 2-ethylhexyl palmitate, isocetyl palmitate, isostearyl palmitate, 2-ethylhexyl stearate, st Examples include monoester oils of straight-chain fatty acids and branched alcohols such as isocetyl oleate, isodecyl oleate, octyldodecyl oleate, and octyldodecyl ricinoleate; monoester oils of branched fatty acids and straight-chain higher alcohols such as cetyl 2-ethylhexanoate, cetostearyl 2-ethylhexanoate, and hexyl isostearate; and monoester oils of branched fatty acids and branched alcohols such as octyldodecyl neopentanoate, isocetyl octanoate, isostearyl octanoate, octyl isononanoate, hexyldecyl neodecanoate, octyldodecyl neodecanoate, 2-ethylhexyl isopalmitate, isocetyl isostearate, isostearyl isostearate, and octyldodecyl isostearate. These components B1 may be used individually or in combination of two or more as appropriate.

[0030] Specific examples of component B2 include diester oils of fatty acids and polyhydric alcohols such as ethylene glycol dioctanoate, ethylene glycol dioleate, propylene glycol dicaprylate, di(caprylic / capric acid)propylene glycol, propylene glycol dicaprate, propylene glycol dioleate, neopentyl glycol dicaprate, and neopentyl glycol dioctanoate; diester oils of dibasic acids such as dioctyl succinate, diisopropyl adipate, diisobutyl adipate, dioctyl adipate, diethyl sebacate, diisopropyl sebacate, and diethylhexyl sebacate; and diester oils of carbonic acid such as dicaprylyl carbonate. These components B2 may be used individually or in combination of two or more as appropriate.

[0031] Specific examples of component B3 include, for example, triester oils of fatty acids and polyhydric alcohols such as glyceryl tricaprylate, glyceryl tri-2-ethylhexanoate, glyceryl tri(caprylic / capric acid), glyceryl triisopalmitate, glyceryl triisostearate, trimethylolpropane tri-2-ethylhexanoate, and trimethylolpropane triisostearate. These components B3 may be used individually or in appropriate combinations of two or more.

[0032] In this invention, component B can be a commercially available product. The commercially available product of component B is not particularly limited, as long as the desired effect is achieved, whether as a single raw material or a mixed raw material with other components.

[0033] The content of component B in the semi-solid warming cleansing cosmetic of the present invention is not particularly limited as long as the desired effect is sufficiently achieved. However, from the viewpoint of improving compatibility with sebum and makeup residue, achieving a remarkably superior cleansing effect, and providing a unique feel when spread, it is preferably 45% by mass or more, and more preferably 50% by mass or more, of 100% by mass of the cosmetic. Furthermore, from the viewpoint of suppressing deterioration of the feel due to the formulation becoming too soft, it is preferably 80% by mass or less, and more preferably 75% by mass or less, of 100% by mass of the cosmetic. Note that the above content of component B is the amount converted to pure content.

[0034] In the present invention, from the viewpoint of further enhancing the cleansing effect, it is preferable that the mass ratio of the amount of monoester oil to the total amount of ester oil (amount of monoester oil / total amount of ester oil) is in the range of 0.5 to 0.85, and more preferably in the range of 0.55 to 0.8.

[0035] Furthermore, from the viewpoint of further enhancing compatibility with sebum and makeup residue, it is preferable that the mass ratio of the amount of diester oil to the total amount of ester oil (amount of diester oil / total amount of ester oil) be within the range of 0.05 to 0.25, and more preferably within the range of 0.08 to 0.2.

[0036] Furthermore, in order to further enhance the unique melting texture and thick feel when spread, it is preferable that the mass ratio of the amount of triester oil to the total amount of ester oil (amount of triester oil / total amount of ester oil) be in the range of 0.1 to 0.3, and more preferably in the range of 0.15 to 0.25.

[0037] In the present invention, in order to exhibit excellent effects, it is sufficient to prepare the mixture while satisfying any of the mass ratios of the amount of each ester oil to the total amount of ester oils described above. However, from the viewpoint of further enhancing the unique effects of the present invention during spreading, it is more preferable to prepare the mixture while satisfying all of the mass ratios of the amount of each ester oil to the total amount of ester oils.

[0038] In addition, in the present invention, in order to exhibit exceptionally superior formulation stability, fully exhibit a unique feel when spread, significantly improve compatibility with sebum and makeup residue, and fully exhibit excellent cleansing effect, the content of component B relative to component A is quality The ratio (component B / component A) is preferably prepared to satisfy the range of 5 to 25, more preferably to satisfy the range of 8 to 20, and most preferably to satisfy the range of 11 to 18.

[0039] The above content quality If the ratio (component B / component A) is less than 5, the formulation becomes too hard, which is undesirable because it not only makes it difficult to remove from the container but also makes it less compatible with sebum and makeup, resulting in a poor user experience during cleansing. On the other hand, if the above content is quality If the ratio (component B / component A) is greater than 25, the formulation becomes too soft, making it difficult to obtain the unique melting or thick texture when spread, resulting in an inferior user experience, which is undesirable.

[0040] [Component C] The above-mentioned component C is a nonionic surfactant. In this invention, by using the above-mentioned component C, the semi-solid warming cleansing cosmetic of the present invention can be washed off well, and the characteristic sticky feeling that remains on the skin after cleansing can be prevented. In addition, the cleansing effect can be further enhanced. Furthermore, the stability of the formulation can be further enhanced.

[0041] Examples of component C include glycerin fatty acid esters, polyoxyethylene glycerin fatty acid esters, polyglycerin fatty acid esters, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene fatty acids, polyoxyethylene alkyl ethers, polyoxyethylene polyoxypropylene alkyl ethers, and polyoxyethylene hydrogenated castor oil.

[0042] The HLB value of component C is not particularly limited as long as the desired effect is sufficiently achieved, but from the viewpoint of improving washability, it is preferably 2 to 20, and more preferably 2 to 16. These components C may be used individually, or two or more may be used in appropriate combinations.

[0043] Among the above-mentioned components C, it is preferable to use glycerin fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyglycerin fatty acid ester, and polyoxyethylene sorbitan fatty acid ester from the viewpoint of further enhancing the cleansing effect, further improving the ability to wash off after cleansing, and further improving the stability of the formulation, and it is more preferable to use polyoxyethylene glycerin fatty acid ester, polyglycerin fatty acid ester, and polyoxyethylene sorbitan fatty acid ester.

[0044] In this specification, the above polyoxyethylene glycerol fatty acid ester may be referred to as "component C1," the above polyglycerol fatty acid ester as "component C2," and the above polyoxyethylene sorbitan fatty acid ester as "component C3."

[0045] The fatty acids constituting components C1, C2, and C3 described above are not particularly limited, whether saturated fatty acids, unsaturated fatty acids, or condensates (polymers) of these fatty acids, as long as the desired effect is sufficiently achieved. Furthermore, the fatty acids are not particularly limited, whether straight-chain fatty acids or branched fatty acids, as long as the desired effect is sufficiently achieved. In addition, the fatty acids are not particularly limited, whether single-chain or polychain, as long as the desired effect is sufficiently achieved.

[0046] Suitable component C1 includes, for example, polyoxyethylene (caprylic / capric acid) glyceryl, polyoxyethylene glyceryl laurate, polyoxyethylene glyceryl stearate, polyoxyethylene glyceryl oleate, polyoxyethylene glyceryl coconut oil fatty acid, polyoxyethylene glyceryl isostearate, polyoxyethylene glyceryl distearate, polyoxyethylene glyceryl tristearate, polyoxyethylene glyceryl diisostearate, polyoxyethylene glyceryl trioleate, and polyoxyethylene glyceryl triisostearate. These suitable component C1 may be used individually or in combination of two or more as appropriate.

[0047] The average number of moles of ethylene oxide added to component C1 is not particularly limited as long as the desired effect is sufficiently achieved, but it is preferably 2 to 60, and more preferably 2 to 40. When the average number of moles of ethylene oxide added to component C1 is within the above range, the cleansing effect of the semi-solid warming cleansing cosmetic composition of the present invention can be enhanced, and the wash-off after cleansing can be improved.

[0048] Suitable component C2 includes, for example, polyglyceryl caprate, polyglyceryl laurate, polyglyceryl myristate, polyglyceryl palmitate, polyglyceryl stearate, polyglyceryl oleate, polyglyceryl isostearate, polyglyceryl dicaprate, polyglyceryl dimyristate, polyglyceryl distearate, polyglyceryl dioleate, polyglyceryl diisostearate, polyglyceryl trimyristate, polyglyceryl tristearate, polyglyceryl trioleate, polyglyceryl triisostearate, polyglyceryl tetralaurate, and polyglyceryl tetraisostearate. These suitable component C2 may be used individually or in combination of two or more as appropriate.

[0049] The average degree of polymerization of polyglycerin in component C2 is not particularly limited as long as the desired effect is sufficiently achieved, but it is preferably 2 to 12, and more preferably 2 to 10. When the average degree of polymerization of polyglycerin in component C2 is within the above range, it is possible to enhance the cleansing effect of the semi-solid warming cleansing cosmetic composition of the present invention, improve rinsing after cleansing, and also enhance the stability of the formulation.

[0050] Suitable component C3 includes, for example, polyoxyethylene sorbitan laurate, polyoxyethylene sorbitan stearate, polyoxyethylene sorbitan oleate, polyoxyethylene sorbitan isostearate, polyoxyethylene sorbitan coconut oil fatty acid, polyoxyethylene sorbitan tristearate, polyoxyethylene sorbitan triisostearate, and polyoxyethylene sorbitan tetraoleate. These suitable component C3 may be used individually or in combination of two or more as appropriate.

[0051] The average number of moles of ethylene oxide added to component C3 is not particularly limited as long as the desired effect is sufficiently achieved, but it is preferably 2 to 60, and more preferably 2 to 40. When the average number of moles of ethylene oxide added to component C3 is within the above range, the cleansing effect of the semi-solid warming cleansing cosmetic composition of the present invention can be enhanced, and the wash-off after cleansing can be improved.

[0052] In this invention, component C can be a commercially available product. The commercially available product of component C is not particularly limited, as long as the desired effect is achieved, whether as a single raw material or a mixed raw material with other components.

[0053] The content of component C in the semi-solid warming cleansing cosmetic composition of the present invention is not particularly limited as long as the desired effect is sufficiently achieved. However, from the viewpoint of enhancing the cleansing effect, improving the ability to wash off after cleansing, and enhancing formulation stability, it is generally preferable that the content of component C be 5% by mass or more, and more preferably 7% by mass or more, of 100% by mass of the cosmetic composition. Furthermore, from the viewpoint of formulation stability, it is preferable that the content be 20% by mass or less, and more preferably 18% by mass or less, of 100% by mass of the cosmetic composition. Note that the above content of component C is the amount converted to pure content.

[0054] [Component D] The above component D is zeolite. Zeolite is a microporous crystalline aluminosilicate, also known as zeolite. Its chemical composition is given by the general formula: M 2 / n It is represented as O·Al2O3·xSiO2·yH2O (where n is the valence of the Mn cation, x is a number greater than or equal to 2, and y represents the amount of adsorbed water).

[0055] In this invention, by using the above-mentioned component D, it is possible to produce an optimal warming sensation by interacting with the moisture contained in the skin during cleansing. In addition, by using the above-mentioned component D, it is also possible to expect the effect of refining the skin's texture through a massage action due to the moderate scrubbing effect.

[0056] As described above, the semi-solid, warming cleansing cosmetic composition of the present invention can generate an optimal warming sensation during cleansing. This warming effect opens pores, allowing sebum and makeup residues lodged deep within the pores to be lifted. These lifted impurities can be dissolved and removed by components A and B as described above, but because component D itself is porous, it can also adsorb and remove these impurities.

[0057] The component D used is not particularly limited, whether it is a naturally occurring zeolite or an artificially synthesized zeolite, as long as the desired effect is sufficiently achieved. Examples of zeolite crystal structures include type A, type X, type L, type Y, beta, ZSM-5, ferrienite, and mordenite, but are not particularly limited in this invention. Furthermore, zeolites have cations in their crystal structure. Specific cations include potassium, sodium, and calcium, but are not particularly limited in this invention.

[0058] The above-mentioned component D is not particularly limited as long as the desired effect is sufficiently achieved, whether it is a hydrophilic zeolite or a hydrophobic zeolite. However, in this invention, it is preferable to use a hydrophilic zeolite, which has an extremely high water adsorption capacity, because it interacts with the moisture contained in the skin to produce an optimal warming sensation.

[0059] Furthermore, the average particle size of component D is not particularly limited as long as the desired effect is sufficiently achieved, but it is preferable to use a zeolite having a particle size in the range of 0.001 to 200 μm, and more preferably a zeolite having a particle size in the range of 0.01 to 160 μm. By using a zeolite that satisfies the above range, it is possible to fully achieve both an excellent warming effect and a dirt adsorption and removal effect.

[0060] In this invention, component D can be a commercially available product. The commercially available component D is not particularly limited as long as the desired effect is achieved, whether as a single raw material or a mixed raw material with other components. In addition, in this invention, a commercially available product that satisfies the above particle size range may be used as is, or a prepared product obtained by further grinding the commercially available product using a pulverizer may be used.

[0061] The content of component D in the semi-solid warming cleansing cosmetic of the present invention is not particularly limited as long as the desired effect is sufficiently achieved. However, from the viewpoint of achieving an optimal warming effect and adsorbing and removing dirt, it is generally preferable that the content be 10% by mass or more, and more preferably 15% by mass or more, of 100% by mass of the cosmetic. Furthermore, from the viewpoint of suppressing deterioration of the feel when spread, it is preferable that the content be 30% by mass or less, and more preferably 25% by mass or less, of 100% by mass of the cosmetic. Note that the content of component D above is the amount converted to pure content.

[0062] [Component E] The semi-solid, warming cleansing cosmetic of the present invention preferably further contains a plant oil as component E. By using component E, it is possible to enhance the thick, substantial feel when spread and to impart an emollient effect to the skin after cleansing. Since the semi-solid, warming cleansing cosmetic of the present invention exhibits a remarkably superior cleansing effect, post-cleansing skin care is important.

[0063] Specific examples of component E include, for instance, Astrocaryum tucuma seed butter, Astrocaryum murumuru seed butter, African mango kernel butter, avocado butter, rice butter, cocoa butter, Garcinia indica seed butter, sesame seed butter, Sarasa berry seed butter, shea butter, Shorea stenoplate seed butter, Theobroma grandiflorum seed butter, Camellia japonica seed butter, Tritilla roca seed butter, Tritilla roca seed butter, palm butter, Bascia alatifolia seed butter, Bascia butiracea seed butter, Vilorosa linamensis seed butter, Platonia insignis seed butter, Pentadesma butiracea seed butter, Pouteria sapota seed butter, jojoba butter, and mango seed butter. These components E may be used individually or in combination of two or more as appropriate.

[0064] In this invention, component E can be a commercially available product. The commercially available product of component E is not particularly limited, as long as the desired effect is achieved, whether it is a single raw material or a mixed raw material with other components.

[0065] The content of component E in the semi-solid warming cleansing cosmetic composition of the present invention is not particularly limited as long as the desired effect is sufficiently achieved. However, from the viewpoint of enhancing the thick feel when spread and providing an emollient effect, it is generally preferable that the content be 0.0001% by mass or more, and more preferably 0.001% by mass or more, of 100% by mass of the cosmetic composition. Furthermore, from the viewpoint of suppressing deterioration of the cleansing effect, it is preferable that the content be 2% by mass or less, and more preferably 1% by mass or less, of 100% by mass of the cosmetic composition. Note that the above content of component E is the amount converted to pure content.

[0066] [Other ingredients] In addition to the above-mentioned components, the semi-solid, warming cleansing cosmetic composition of the present invention may appropriately incorporate oils that are solid or liquid at room temperature, as long as they do not impair the effects of the present invention. Examples of oils that can be incorporated other than components A and B include higher fatty acids, higher alcohols, and silicone oils. Furthermore, in addition to these components, surfactants other than component C, such as anionic surfactants, cationic surfactants, and amphoteric surfactants; thickening polymers, clay minerals, film-forming agents, UV absorbers, preservatives, whitening agents, anti-inflammatory agents, cooling agents, vegetable oils, plant extracts, plant fermentation extracts, pH adjusters, neutralizing agents, and fragrances may be appropriately incorporated depending on the purpose and application.

[0067] From the viewpoint of providing an optimal warming sensation during cleansing, the semi-solid warming cleansing cosmetic composition of the present invention preferably contains no water, or contains water, with the water content being 1% by mass or less per 100% by mass of the cosmetic composition. That is, the water content in the semi-solid warming cleansing cosmetic composition of the present invention is preferably 0 to 1% by mass, and more preferably 0 to 0.5% by mass.

[0068] The method for producing the semi-solid, warming cleansing cosmetic composition of the present invention is not particularly limited, but can be produced by known methods, for example. Specifically, examples include mixing the above-mentioned components and stirring them using a disper mixer, homomixer, disper mill, etc., but the present invention is not limited to these production methods.

[0069] Because the semi-solid warming cleansing cosmetic of the present invention is in a semi-solid form, it is preferable to fill it into a container that allows for easy dispensing. Specifically, it is preferable to fill it into a wide-mouthed jar container. Furthermore, the semi-solid warming cleansing cosmetic of the present invention may take the form of cosmetics, quasi-drugs, designated quasi-drugs, general merchandise, etc. [Examples]

[0077] (Sample preparation 1) Cosmetics for Examples 1-8 and Comparative Examples 1-8 were prepared according to conventional methods, based on the compositions listed in Tables 1 and 2, and subjected to the following evaluation. The results are shown in Tables 1 and 2.

[0078] (Test Example 1: Evaluation of Formulation Stability) Each sample obtained in the examples and comparative examples was filled into a 90g wide-mouth container and stored in a 40°C constant temperature bath for one week. The state of the agent after storage was visually observed and evaluated according to the evaluation criteria below. The evaluation was carried out by five expert evaluators, and the final decision was made based on the combined evaluations of each evaluator.

[0079] <Evaluation Criteria for Formulation Stability> ○ (Good): Maintains a uniform condition compared to immediately after manufacturing (no changes observed). △ (Insufficient): Compared to immediately after manufacturing, a uniform state is maintained, but slight separation of liquid is observed. × (Defective): Compared to immediately after manufacturing, it does not maintain a uniform state, obvious liquid separation is observed, or it does not become semi-solid.

[0080] In the evaluation of formulation stability in Test Example 1 above, each sample that received a result of "○ (good)" or "△ (insufficient)" was subjected to the following tests.

[0081] (Test example 2: Evaluation of usability during extended use) Each sample (1g) was applied to the back of a hand stained with lipstick, and then spread in small circular motions with the fingertips. Sensory evaluation was conducted according to the following criteria for "changes in the substance and its feel (usability (1))", "thickness (usability (2))", and "compatibility with makeup stains". The evaluation was carried out by five expert evaluators, and the final result was determined by combining the evaluations of each evaluator.

[0082] <Evaluation criteria for usability during extended use (1)> ○(Good): The semi-solid material melts and crumbles, providing a pleasant user experience. △ (Insufficient): The semi-solid formulation does not melt or crumble easily, resulting in an inferior user experience. × (Poor): The semi-solid agent does not melt or crumble, resulting in an unpleasant texture.

[0083] <Evaluation criteria for usability during extended use (2)> ○(Good): Provides a thick, substantial feel and spreads smoothly. △ (Insufficient): While it spreads smoothly, it lacks the substantial feel of a thicker product. × (Defective): Does not provide a thick, substantial feel.

[0084] <Evaluation Criteria for How Well It Blends with Makeup> ○(Good): Easily blends with makeup (dirt) without needing to apply much pressure with your fingers. △ (Insufficient): You need to rub it in with your fingers with a little pressure to blend it with the makeup (dirt). × (Poor): It requires considerable force to rub in order to blend with makeup (dirt).

[0085] (Test Example 3: Evaluation during cleansing) Each sample (3g) was applied to the entire face, which was already made up. Then, the participants cleansed the area with small circular motions using their fingertips, focusing on areas where makeup was a concern, for one minute. After that, they rinsed thoroughly with 40°C warm water and patted their faces dry with a towel.

[0086] The usage tests focused on the "warming sensation" during cleansing, "wash-off" during washing, and "cleansing effect (removal of makeup and sebum clogged in pores)" after towel drying. Sensory evaluations were conducted according to the evaluation criteria below. The evaluations were carried out by five expert evaluators, and the final result was determined by combining the evaluations of each evaluator.

[0087] <Evaluation Criteria for Warmth Sensation> ○ (Good): You feel the optimal warmth. △ (Insufficient): You feel warmth, but it's not enough. ×(Poor): No sensation of warmth.

[0088] <Evaluation criteria for washability> ○ (Good): Excellent at washing off △ (Insufficient): Poor washability × (Poorly remembered, poorly washable)

[0089] <Criteria for evaluating cleansing effectiveness> ○ (Good): The cleansing process gives the feeling that not only makeup residue but also sebum buildup in the pores has been removed. △ (Insufficient): While makeup residue is removed through cleansing, there is no feeling that sebum and dirt clogged in the pores have been sufficiently removed. × (Poor): Unable to adequately remove makeup and sebum during cleansing.

[0090] [Table 1]

[0091] [Table 2]

[0092] The results shown in Tables 1 and 2 indicate that the semi-solid, warming cleansing cosmetic formulations of the present invention obtained in each example exhibit significantly superior formulation stability compared to those obtained in each comparative example, with no separation or synelution of the formulation. Furthermore, the semi-solid, warming cleansing cosmetic formulation of the present invention creates a unique, melting sensation upon application and provides a sufficiently thick texture, indicating excellent compatibility with sebum and makeup residue.

[0093] Furthermore, the semi-solid, warming cleansing cosmetic of the present invention not only removes makeup residue, but also generates an optimal warming sensation during cleansing, which allows it to remove even sebum buildup deep within the pores. As a result, it exhibits a significantly superior cleansing effect compared to conventional cleansing cosmetics.

[0094] In contrast, Comparative Examples 1 and 2, which do not contain component A, an essential component of the present invention, and Comparative Examples 3 and 4, which do not contain component B, do not form a semi-solid dosage form. Furthermore, Comparative Examples 5 and 6, which do not contain component C, an essential component of the present invention, exhibit poor formulation stability, resulting in a lack of the characteristic feel upon application of the present invention and poor washability, thus failing to achieve a superior cleansing effect. Moreover, Comparative Examples 7 and 8, which do not contain component D, an essential component of the present invention, do not provide the optimal warming sensation during cleansing, indicating an inferior cleansing effect. These results demonstrate that the unique effects of the present invention can only be maximized by satisfying the essential components of the present invention.
