Description

Technical Field

[0001] This invention relates to water-based cleaning agent compositions. Background Technology

[0002] In recent years, the use of oil-soluble silicone resins such as trimethylsiloxysilicate (TMS) in long-lasting makeup products to form a firm, water-repellent film on the skin's surface has become widespread. This technology not only resists sweat and sebum but also physically prevents makeup from fading. However, since the silicone resins used in this method are oil-soluble, makeup products containing a high concentration of these ingredients are difficult to remove with water-based cleansers and require oil-based makeup removers.

[0003] However, oil-based or liquid makeup removers are sticky and take time to remove dirt and grime, or they may leave a sticky feeling during the process. Furthermore, even after removal, a sticky or greasy feeling often remains. Therefore, some people use a facial cleanser afterward for a double cleansing, which results in prolonged friction on the skin during makeup removal.

[0004] On the other hand, awareness of skin care has increased, and more and more people do not want to rub their skin for a long time when removing makeup. As a result, it is difficult to simultaneously achieve "thorough removal of makeup" and "removal without rubbing the skin".

[0005] In addition, water-based makeup removers that can remove makeup and other oily dirt are being researched.

[0006] For example, Patent Document 1 describes a water-based makeup remover containing polyoxyethylene (caprylic / capric acid) glyceryl ester, polyoxyethylene coconut oil fatty acid glyceryl ester, and polyols, which can remove oily dirt such as makeup, inhibit stickiness or rough skin caused by excessive degreasing, and provide a continuous moisturizing feeling.

[0007] (Patent Document 1) Japanese Patent Application Publication No. 2010-70521 Summary of the Invention

[0008] This invention relates to a water-based cleaning agent composition, comprising the following components (A), (B), (C), and (D).

[0017] (C) Polyols;

[0018] (D) Water;

[0019] The mass ratio of component (A) to component (B) is 1 to 25. Detailed Implementation

[0020] It is known that water-based makeup removers are ineffective at removing long-lasting makeup products containing a significant amount of oil-soluble silicone resins.

[0021] This invention relates to a water-based cleansing composition that also has high cleansing power for long-lasting makeup cosmetics formulated with oil-soluble silicone resins such as TMS.

[0022] The inventors have discovered that by combining a specific nonionic surfactant with an HLB of 13 or more, a specific nonionic surfactant with an HLB of 10 or less, and a polyol in a specific ratio, it is possible to obtain a water-based cleansing agent composition that still has high cleansing power even for color cosmetics containing oil-soluble silicone resins and the like, which have been enhanced for long-lasting use.

[0023] The water-based cleansing composition of the present invention still has high removal potential even for makeup cosmetics that form a relatively hard film using oil-soluble silicone resins such as TMS.

[0024] Component (A) is a nonionic surfactant with an HLB value of 13 or higher selected from (a1), (a2), and (a3).

[0025] (a1) Polyoxyethylene lauryl ester,

[0026] (a2) Polyoxyethylene (octanoic acid / decanoic acid) glycerides,

[0027] (a3) Polyoxyethylene coconut oil fatty acid glycerides.

[0028] Here, HLB is an indicator of hydrophilic-lipophilic balance, which is the value obtained in this specification by Griffin's following formula.

[0029]

[0030] Component (A) is a hydrophilic nonionic surfactant with a specific structure, which, together with component (B), removes makeup and cosmetics that have enhanced long-lasting effects. Therefore, component (A) is preferably capable of cleansing and removing makeup on its own, and by combining it with the lipophilic nonionic surfactant of component (B), its removal potential is significantly enhanced.

[0031] Here, "removal potential" refers to, for example, the removal performance of cosmetics applied to a virtual skin model substrate under certain physical conditions when removed by applying a specified physical force. This "removal performance" is determined by calculating the removal rate based on the color difference measurement of the cosmetics before and after cleaning on the model substrate, and then classifying the removal rate accordingly.

[0032] In addition, the term "significant improvement in removal potential" means, for example, that the removal potential in the embodiment is improved by more than one level compared to the use of component (A) alone, and the absolute level of removal potential reaches level A or B (removal rate of more than 50%).

[0033] Regarding the nonionic surfactant of component (A), from the viewpoint of ensuring water solubility, the HLB content is 13 or higher, preferably 14 or higher.

[0034] Regarding the average number of moles of polyoxyethylene (POE) groups added to component (A), from the viewpoint that the HLB is 13 or more, it is preferred that (a1) has 9 or more moles, (a2) has 6 or more moles, and (a3) ​​has 7 or more moles. From the viewpoint that the makeup removal potential exerted by component (A) alone is preferred, it is preferred that (a1) has 30 or less moles, (a2) has 20 or less moles, and (a3) ​​has 40 or less moles. It is more preferred that (a1) has 20 or less moles, (a2) has 10 or less moles, and (a3) ​​has 20 or less moles. Specifically, (a1) is preferably POE (12) monolaurate, (a2) is preferably POE (6) (caprylic / capric acid) glyceride or POE (7) (caprylic / capric acid) glyceride, and (a3) ​​is preferably POE (7) coconut oil fatty acid glyceride or POE (8) coconut oil fatty acid glyceride.

[0035] Regarding component (A), one type or two or more types can be used. When two or more nonionic surfactants are used, their HLB is calculated by taking the arithmetic mean of the HLB values ​​of each nonionic surfactant type according to their content ratio, and then defining it as the "mixed HLB". Even if the HLB of any one of (a1), (a2), and (a3) ​​is less than 13, as long as the mixed HLB of these is 13 or more, it still corresponds to component (A) in this invention.

[0036] Regarding the content of ingredient (A), from the viewpoints of cleansing power (removal potential), ease of removal from the skin, and the feeling of bare skin after removal, it is preferably 3% by mass or more, more preferably 5% by mass or more, and even more preferably 10% by mass or more in the total composition, and preferably 30% by mass or less, more preferably 25% by mass or less, and even more preferably 20% by mass or less in the total composition. Furthermore, the content of ingredient (A) in the total composition is preferably 3 to 30% by mass, more preferably 5 to 25% by mass, and even more preferably 10 to 20% by mass.

[0037] Component (B) is a nonionic surfactant with an HLB value of less than 10 selected from (b1), (b2) and (b3):

[0038] (b1) Mono-fatty acid esters or ethers of glycerol or diglycerol,

[0039] (b2) POE monofatty acid esters having an average addition molar number of POE groups of 1 to 5, or POE glycerol monofatty acid esters having an average addition molar number of POE groups of 1 to 5.

[0040] (b3) Sorbitan monofatty acid ester.

[0041] Component (B) is a lipophilic nonionic surfactant with a specific structure. It acts on cosmetic films (such as foundation films) formed by oil-soluble silicone resins such as TMS, and has the effect of softening their hard surfaces. Furthermore, by combining it with component (A), it dissolves in water to provide high cleaning power.

[0042] Regarding the nonionic surfactant of component (B), from the viewpoint that it actively adsorbs onto the coating surface in aqueous solution and softens the coating components when combined with component (A), the HLB is preferably 10 or less, more preferably 8 or less. From the viewpoint that an appropriate amount of component (B) can be stably dissolved by component (A), the HLB of component (B) is preferably 2 or more, more preferably 4 or more.

[0043] Regarding component (B), from the viewpoint of having an HLB of 10 or less, examples of component (b1) could be: monoesters formed from oleic acid, stearic acid, or isostearic acid with glycerol or diglycerol; or monoethers formed from oleyl alcohol, stearyl alcohol, or isostearyl alcohol with glycerol or diglycerol. Examples of component (b2) could be: POE monomyristate with an average addition molar number of POE groups of 1 to 5, POE monolaurate with an average addition molar number of POE groups of 1 to 5, POE glyceryl monooleate with an average addition molar number of POE groups of 1 to 5, POE glyceryl monostearate with an average addition molar number of POE groups of 1 to 5, POE glyceryl monoisostearate with an average addition molar number of POE groups of 1 to 5, etc. In addition, examples of component (b3) could be: sorbitan monostearate, sorbitan monooleate, sorbitan monoisostearate, etc.

[0044] From the viewpoint of ensuring low-temperature stability, (b1) it is preferable to use a monoester formed by oleic acid or isostearic acid and glycerol or diglycerol, or a monoether formed by oleyl alcohol or isostearyl alcohol and glycerol or diglycerol; (b2) it is preferable to use POE monolaurate with an average addition molar number of POE groups of 1 to 5, or POE glycerol monooleate with an average addition molar number of POE groups of 1 to 5, or POE glycerol monoisostearate with an average addition molar number of POE groups of 1 to 5; and (b3) it is preferable to use sorbitan monooleate or sorbitan monoisostearate.

[0045] Regarding component (B), one or more can be used in combination. Even if any one of (b1), (b2), and (b3) has an HLB value exceeding 10, as long as the combined HLB value of these is below 10, it still corresponds to component (B) in this invention.

[0046] Regarding the content of component (B), from the viewpoint of being dissolved by component (A) and softening the coating surface, it is preferably 0.3% by mass or more, more preferably 0.5% by mass or more, further preferably 1% by mass or more, and preferably 10% by mass or less, more preferably 8% by mass or less, and further preferably 5% by mass or less in the total composition. Furthermore, the content of component (B) in the total composition is preferably 0.3 to 10% by mass, more preferably 0.5 to 8% by mass, and further preferably 1 to 5% by mass.

[0047] In this invention, the mass ratio (A) / (B) of component (A) to component (B) is important for improving the removal potential of makeup. From the viewpoint of utilizing component (A) to dissolve component (B), which has low water solubility, and thus improving removal potential, (A) / (B) is preferably 1 or more, more preferably 1.5 or more, and even more preferably 2 or more. Furthermore, from the viewpoint of relatively sufficiently increasing component (B) to improve removal potential, (A) / (B) is preferably 25 or less, more preferably 15 or less, and even more preferably 10 or less.

[0048] In addition, the mass ratio of component (A) to component (B) (A) / (B) is 1 to 25, preferably 1.5 to 15, and more preferably 2 to 10.

[0049] The aqueous cleansing composition of the present invention is an aqueous solution of a nonionic surfactant, thus the skin does not feel tight after rinsing like with a facial cleanser, nor does it require physical emulsification like oils. It has the property of spontaneously mixing with water, allowing for quick rinsing. From the viewpoint of maintaining the makeup removal potential and reducing the stickiness when removing makeup from the skin, resulting in a bare skin feel after removal, the total content of components (A) and (B) in the total composition ((A) + (B)) is preferably 5% by mass or more, more preferably 7% by mass or more. Furthermore, from the viewpoint of reducing residue on the skin after removal and effectively obtaining a bare skin feel, it is preferably 25% by mass or less, more preferably 20% by mass or less.

[0050] Furthermore, the total content ((A)+(B)) of components (A) and (B) in the overall composition is preferably 5 to 25% by mass, more preferably 7 to 20% by mass.

[0051] The polyol in component (C) promotes the solubility of nonionic surfactants in water and enhances their effect on color cosmetics. Examples of such polyols commonly used in cleansing compositions include: ethylene glycol, diethylene glycol, hexanediol, polyethylene glycol with an average molecular weight of less than 1000, propylene glycol, dipropylene glycol, polypropylene glycol with an average molecular weight of less than 1500, 1,2-propanediol, isopentyl glycol, 1,3-butanediol, dibutylene glycol, glycerin, diglycerin, triglycerin, tetraglycerin, hexaglycerin, decaglycerin, trimethylpropanol, etc.

[0052] Among these, from the viewpoint of improving solubility and expanding the temperature range for maintaining transparency and uniformity, it is preferable to use components such as 1,3-butanediol, dibutanediol, and 1,2-propanediol, which typically increase the cloud point of POE addition-type nonionic surfactants.

[0053] Regarding the polyol of component (C), one type can be used alone or two or more types can be used in combination. Regarding its content, from the viewpoint of promoting the dissolution of components (A) and (B) and exerting cleaning power, it is preferably 5% by mass or more, more preferably 10% by mass or more, further preferably 20% by mass or more, and preferably 50% by mass or less, more preferably 45% by mass or less, and further preferably 40% by mass or less in the total composition. Furthermore, the content of component (C) in the total composition is preferably 5 to 50% by mass, more preferably 10 to 45% by mass, and further preferably 20 to 40% by mass.

[0054] In this invention, water in component (D) acts as a medium. Regarding its content, from the viewpoint of controlling the solubility of the surfactant together with component (C) and exerting cleaning power, it is preferably 30% by mass or more, more preferably 40% by mass or more, further preferably 50% by mass or more, and preferably 80% by mass or less, more preferably 70% by mass or less, and further preferably 60% by mass or less in the total composition. Furthermore, the water content of component (D) in the total composition is preferably 30-80% by mass, more preferably 40-70% by mass, and further preferably 50-60% by mass.

[0055] As described above, the polyol in component (C) plays a role in controlling the solubility of components (A) and (B) while exerting its potential to remove makeup. If there is too little, the cleansing power of the surfactant may not be fully utilized, while if there is too much, it may impair the cleansing power. Therefore, the balance between the polyol in component (C) and the water in component (D) is important. Regarding the mass ratio (C) / (D) of component (C) to component (D), from the viewpoint of fully utilizing the removal potential, it is preferably 0.1 or more, more preferably 0.25 or more. In addition, from the viewpoint of preventing the critical cell bundle concentration (CMC) from increasing indefinitely and inhibiting the separation of the lipophilic nonionic surfactant of component (B) due to the disruption of its interaction with the hydrophilic nonionic surfactant of component (A), it is preferably 1.3 or less, more preferably 1.25 or less.

[0056] Furthermore, the mass ratio of component (C) to component (D) (C) / (D) is preferably 0.1 to 1.3, more preferably 0.25 to 1.25.

[0057] In this invention, the mass ratio ((A)+(B)) / (D) of the total content of components (A) and (B) to component (D) is preferably 0.8 or less, more preferably 0.6 or less, and even more preferably 0.35 or less, from the viewpoint of rinsing properties or the feeling of bare skin after removal.

[0058] The aqueous cleaning composition of the present invention may further contain (E) one or more selected from amphoteric surfactants and anionic surfactants, in which case the rinsing performance and other removal properties or the feeling on the skin can be further improved. In addition, when it is used in a foam dispensing container, the foam quality can also be improved.

[0059] Examples of amphoteric surfactants commonly used in detergent compositions include alkyl sulfonyl betaine, alkyl hydroxy sulfonyl betaine, alkyl carbonyl betaine, alkyl amide hydroxy sulfonyl betaine, alkyl amide amine betaine, and alkyl imidazoline betaine. Preferably, the amphoteric surfactant has 8 to 20 alkyl carbons, more preferably 8 to 14.

[0060] Among these, from the viewpoint of ease of rinsing and other removal properties, as well as foaming, the amphoteric surfactant is more preferably one or more selected from alkylamidopropyl betaine and alkylhydroxysulfonate, which are alkyl groups having 8 to 14 carbon atoms. Alkylhydroxysulfonate is more preferred, and laurylhydroxysulfonate is even more preferred.

[0061] Regarding the amphoteric surfactant, one type or two or more types may be used. Regarding its content, from the viewpoint of improving the bare skin feel after cleansing and maintaining cleansing power, it is preferably 0.5% by mass or more, more preferably 1% by mass or more in the total composition. From the viewpoint of maintaining cleansing power, it is preferably 4% by mass or less, more preferably 3% by mass or less.

[0062] As an anionic surfactant, any ingredient commonly used in detergent compositions is acceptable, such as: carboxylic acid surfactants like fatty acid salts, alkyl ether carboxylates, and polyoxyethylene alkyl ether carboxylates; sulfates like alkyl sulfates, alkyl ether sulfates, and polyoxyethylene alkyl ether sulfates; sulfonates like alkyl sulfosuccinates, polyoxyalkylene sulfosuccinates, α-olefin sulfonates, and hydroxyalkane sulfonates; and N-acyl amino acid salts, N-acylalkyl taurines, and POE phosphates.

[0063] Of these, from the viewpoint of foaming properties and ensuring stability at low temperatures, it is preferable to contain at least one of POE lauryl ether carboxylate, POE lauryl ether sulfate, and POE phosphate.

[0064] Regarding anionic surfactants, one or more types may be used, and regarding their content, from the viewpoint of improving the feel of bare skin and maintaining cleansing power, it is preferably 0.2% by mass or more, more preferably 0.5% by mass or more in the total composition, and from the viewpoint of maintaining cleansing power, it is preferably 2% by mass or less, more preferably 1% by mass or less.

[0065] Regarding ingredient (E), one type or two or more types can be used, and amphoteric surfactants and anionic surfactants can be used in combination.

[0066] Regarding the content of ingredient (E), from the viewpoint of improving the feel of bare skin and maintaining cleansing power, it is preferably 0.2% by mass or more, more preferably 0.5% by mass or more, and preferably 4% by mass or less, more preferably 3% by mass or less in the total composition. Furthermore, regarding the content of ingredient (E), from the viewpoint of maintaining cleansing power, it is preferably 0.2 to 4% by mass, more preferably 0.5 to 3% by mass in the total composition.

[0067] In this invention, from the viewpoint of improving rinsing performance and skin-feel, the mass ratio of component (E) to the total content of components (A) and (B) (E) / ((A)+(B)) is preferably 0.03 or more. On the other hand, from the viewpoint of avoiding the addition of charged surfactants which would cause the HLB of the system to become hydrophilic, thereby reducing the efficiency of makeup removal on oily dirt and affecting the makeup removal rate, (E) / ((A)+(B)) is preferably 0.15 or less.

[0068] Furthermore, the mass ratio of component (E) to the total content of components (A) and (B) (E) / ((A)+(B)) is preferably 0.03 to 0.15.

[0069] In the aqueous cleansing composition of the present invention, oily components (including fragrances) other than component (B) may be further contained, without impairing cleansing power and transparency. Regarding the content of oily components (including fragrances) other than component (B), from the viewpoint of ease of removal from the skin, it is preferably 0.3% by mass or less, more preferably 0.2% by mass or less in the total composition. From the same viewpoint, the content of components other than fragrances in the oily components other than component (B) in the total composition is preferably 0.1% by mass or less, more preferably 0.01% by mass or less.

[0070] In addition to the above-mentioned ingredients, the aqueous cleaning agent composition of the present invention may further contain ingredients commonly used in cleaning agent compositions. Examples include: surfactants other than those mentioned above; lower alcohols such as ethanol and isopropanol; aromatic alcohols such as benzyl alcohol and benzyloxyethanol; cellolytic agents such as ethyl cellolytic and butyl cellolytic; carbitols such as ethyl carbitol and butyl carbitol; moisturizing ingredients such as sugars (derivatives) or amino acids (derivatives), animal and plant (protein) derivatives, and animal and plant extracts; organosilicon derivatives such as polyoxyalkylene modified organosilicon; polymer compounds; inorganic or organic salts such as sodium sulfate, sodium carbonate, sodium bicarbonate, potassium chloride, sodium chloride, and sodium citrate; pH adjusters such as acids and alkalis; anti-inflammatory agents such as glycyrrhetinic acid, glycyrrhizic acid, and their derivatives; bactericides such as isopropyl cresol; preservatives, metal ion blockers, antioxidants, ultraviolet absorbers, fragrances, vitamins, natural pigments, and colorants such as tarcolorants.

[0071] The aqueous cleansing composition of the present invention is preferably in a liquid state at 25°C. "Liquid state" means that it spreads immediately upon being released into the palm of the hand without retaining its shape; this state is generally achieved as long as the viscosity at 25°C is below 3000 mPa·s. On the other hand, lower viscosity is advantageous because it spreads easily on the skin and blends with makeup, thereby reducing the time required for skin rubbing. From this viewpoint, the viscosity of the aqueous cleansing composition at 25°C is preferably below 100 mPa·s, more preferably below 50 mPa·s, and even more preferably below 30 mPa·s.

[0072] In this invention, the viscosity of the water-based cleaning agent composition is measured using a Type B viscometer (TVB-10 type viscometer, manufactured by Toki Sangyo Co., Ltd.) at 25°C for 1 minute.

[0073] Viscosities less than 100 mPa·s were measured using rotor No.1 at 60 rpm; viscosities between 100 and 199 mPa·s were measured using rotor No.1 at 30 rpm; viscosities between 200 and 499 mPa·s were measured using rotor No.1 at 12 rpm; and viscosities above 1000 mPa·s were measured using rotor No.2 at 12 rpm.

[0074] The aqueous cleansing composition of the present invention is aqueous, thus it mixes easily with water, is non-sticky, easy to rinse, and leaves the skin feeling clean and bare after rinsing. Furthermore, as mentioned above, these effects are enhanced by its liquid form (low viscosity), and it spreads easily on the skin, quickly demonstrating its cleansing power. Additionally, it can be easily absorbed into sheets or cotton pads and can also be used by wiping.

[0075] In particular, from the viewpoint of easy penetration of the sheet or cotton pad when used by wiping and excellent dispensing properties when used in a foam dispensing container, the viscosity of the water-based cleaning agent composition at 25°C is preferably 30 mPa·s or less.

[0076] The aqueous cleaning composition of the present invention can be manufactured by first mixing (B) an oleophilic nonionic surfactant with (A) a hydrophilic nonionic surfactant, then adding (C) a polyol and (D) water, and mixing uniformly. Component (E) can be added appropriately after preparing the aqueous solution.

[0077] The aqueous cleansing composition of the present invention preferably exists as a transparent single liquid phase at 25°C. Here, "transparent single liquid phase" refers to a transparent appearance that does not separate, with each component uniformly dissolved in the others. In this state, the interaction between the nonionic surfactants of components (A) and (B) enhances the makeup removal potential, resulting in excellent removal from the skin, such as rinsing, and leaving the skin feeling bare after washing. Furthermore, if the surfactants form a higher-order bond structure, the appearance will be translucent; this state is also considered a single liquid phase. When the system separates into two phases, appearing white and cloudy or in a two-layered state, it is difficult to obtain the desired properties described above.

[0078] The aqueous cleansing composition of the present invention is an aqueous solution primarily composed of nonionic surfactants as the cleansing base, making it difficult to directly handle and foam for use. However, for example, by dispensing it into a foam dispensing container, foam can be forcibly formed. This foam formation not only provides the convenience of uniformly applying the product to the skin while maintaining its shape, but also further enhances makeup removal by applying the foam to the skin. In other words, the foam composed of the nonionic surfactant aqueous solution breaks upon contact with dirt; although it initially produces no foam, it is forcibly foamed. At this point, the surface energy of the foam is converted into physical force and acts on the makeup film surface. In particular, the aqueous cleansing composition of the present invention has high removal potential; therefore, even minute amounts of energy acting on the skin surface can be observed as differences in makeup removal performance.

[0079] From the viewpoint of ease of use or cleaning power, the aqueous cleansing composition of the present invention is preferably applied to the skin in a foam state. From this viewpoint, it is preferable to provide it in the form of a cleanser filled in an aerosol or non-aerosol foam dispensing container.

[0080] As a foam dispensing container, any container capable of mixing the cleaning agent composition with air and dispensing it in the form of foam can be used. However, from the viewpoint of environmental convenience and ease of disposal when using it as a makeup remover, a non-aerosol foaming container is preferred. Examples include pump-type foaming containers that dispense foam using a pump head and squeeze-type foaming containers that dispense foam by pressing the can body. Specifically, examples include foaming containers manufactured by Yoshino Kogyo Co., Ltd. and Yamato Seikan Co., Ltd. Additionally, foaming containers incorporating foaming components described in Japanese Patent Application Publication Nos. 7-315463, 8-230961, 2005-193972, and 2019-107644 can also be used. From the viewpoint of obtaining dense and elastic foam, a pump-type foaming container that dispenses foam using a pump head is preferred.

[0081] In particular, from the viewpoint of high foaming performance and wide tolerance for the viscosity or properties of the solution, it is preferable to use a pump-type foaming container having the gas-liquid mixing component described in Japanese Patent Application Publication No. 2019-107644. That is, as described in claim 1 of that publication, the gas-liquid mixing component has: a liquid flow path through which liquid supplied from a liquid supply section to a mixing section passes, and a gas flow path through which gas supplied from a gas supply section to the mixing section passes. The liquid flow path includes adjacent liquid flow paths having liquid inlets that are open to the mixing section. The gas flow path includes a plurality of adjacent gas flow paths, each of which has a gas inlet that is open to the mixing section. The liquid inlets are disposed at corresponding positions at the confluence of the gases supplied from the plurality of adjacent gas flow paths to the mixing section via the gas inlets.

[0082] For pump-type foaming containers, the foam quality or the pressing pressure during use is easily affected by the viscosity of the contents. In order to dispense foam in the form of foam within the normal temperature range and to ensure a smooth dispensing pressure, the viscosity of the aqueous detergent composition of the contents is preferably 50 mPa·s or less at 25°C, and more preferably 30 mPa·s or less when the foaming properties of the solution itself are low, as in the present invention.

[0083] The aqueous cleaning composition of the present invention is preferably filled in a foam dispensing container and provided in a foam form; in other words, it is preferably a cleaning agent that contains the aqueous cleaning composition and the foam dispensing container thereon.

[0084] Furthermore, the aqueous cleansing composition of the present invention is also suitable for being absorbed into a sheet or cotton pad before contact with the skin to remove makeup, etc. Alternatively, after applying the aqueous cleansing composition to the skin, a sheet or cotton pad can be used to wipe away makeup and the aqueous cleansing composition together.

[0085] The aqueous cleansing composition of the present invention is preferably used for skin cleansing, and more preferably for use as a facial cleanser or makeup remover.

Here, a method close to actual use was employed: the product was applied to a large area of ​​foundation using finger massage, and its removal rate was measured.

[0208] On a 7cm x 12cm piece of white artificial leather (made by OKAMOTO Chemical Co., Ltd., LAFORET white), apply foundation (REVLON COLORSTAY MAKEUP N, shade 370) evenly with your fingers over a 5cm x 10cm area, using a method where the amount is 0.04 to 0.05g. Let it dry for at least 2 hours.

[0209] Next, apply 0.2g of each water-based cleaning agent composition as a liquid, or form a foam, place it on the foam and then pop it. Gently massage the mixture, applying 70g of pressure with two fingers while making 10 overlapping circles of approximately 3cm in diameter on the entire surface to blend it. Then, rinse the water-based cleaning agent compositions with running water.

[0210] In addition, when foam is formed, the water-based cleaning agent composition is filled into the foam dispensing container (dispensing container B), and then the foam is dispensed from the container.

[0211] Using a colorimeter, the color difference (L, a, b) of a white artificial leather sheet was measured at 10 locations before foundation application, after foundation application, and after cleaning. The cleaning removal rate was calculated, and the average value was obtained. The results were then evaluated according to the following criteria.
