Description

Technical Field

[0001] The present invention relates to an aqueous cleaning composition.

Background Art

[0002] In recent years, for sustainable makeup cosmetics, for example, an oil-soluble silicone resin such as trimethylsiloxysilicate (TMS) is blended to form a hard water-repellent makeup coating film on the skin surface, and a technique for preventing makeup collapse not only in terms of sweat and sebum resistance but also physically has been widely used. Since the silicone resin used in this way is oil-soluble, makeup cosmetics containing a large amount of these are difficult to remove with an aqueous cleaning agent, and it was necessary to remove them with makeup remover using an oil agent as a cleaning base. However, in oil-type or liquid-type makeup removers using an oil agent as a cleaning base, they are sticky and take time to remove together with dirt, or become sticky during the removal process. Furthermore, stickiness and greasiness often remain even after removal. For this reason, some people perform double face washing by washing their face with facial wash after that. In that case, as a result, they had to rub their skin for a long time to remove makeup. On the other hand, the awareness of taking care of the skin is increasing, and the number of people who do not want to rub their skin for a long time when removing makeup is increasing. Thus, it has become difficult to achieve both thoroughly removing makeup and removing it without rubbing the skin.

[0003] In addition, aqueous cleansing cosmetics that can remove oil stains such as makeup have been studied. For example, Patent Document 1 describes that an aqueous cleansing cosmetic containing polyoxyethylene (caprylic / capric acid) glyceryl, polyoxyethylene coconut oil fatty acid glyceryl, and a polyhydric alcohol can remove oil stains such as makeup, suppress stickiness and skin roughness due to excessive degreasing, and impart a persistent moist feeling.

[0005] However, with conventional aqueous cleansing cosmetics, it has been difficult to thoroughly remove long-lasting makeup cosmetics containing a large amount of oil-soluble silicone resin. The present invention relates to an aqueous cleaning agent composition having high detergency even against makeup cosmetics with enhanced durability by blending an oil-soluble silicone resin such as TMS. [Means for Solving the Problems]

[0006] The present inventors have found that by combining and using a specific nonionic surfactant having an HLB of 13 or more, a specific nonionic surfactant having an HLB of 10 or less, and a polyol in a specific ratio, an aqueous cleaning agent composition having high detergency can be obtained even against long-lasting makeup cosmetics containing an oil-soluble silicone resin or the like.

Effect of the Invention

[0008] The aqueous cleaning composition of the present invention can have a high removal potential even for makeup cosmetics that form a hard coating film with an oil-soluble silicone resin such as TMS.

Embodiments for Carrying Out the Invention

[0009] Component (A) is a nonionic surfactant having an HLB of 13 or more selected from (a1), (a2), and (a3). (a1) Polyoxyethylene laurate, (a2) Polyoxyethylene (caprylic / capric acid) glyceryl, (a3) Polyoxyethylene coconut oil fatty acid glyceryl. Here, HLB is an index indicating the hydrophilic-lipophilic balance, and in this specification, it is determined by the following formula by Griffin.

[0010]

Equation

[0011] Component (A) is a hydrophilic nonionic surfactant having a specific structure, and together with component (B), it functions to remove makeup cosmetics with enhanced persistence. Therefore, component (A) preferably has a certain degree of cleaning and removal potential even alone, and when combined with the lipophilic nonionic surfactant of component (B), a significant improvement in the removal potential can be observed. Here, the removal potential refers to, for example, the removal performance when makeup cosmetics applied on the model substrate of the pseudo-skin in the examples are removed by applying a predetermined physical force under certain physical conditions. It is ranked and determined by the removal rate calculated from the color difference measurement of the makeup cosmetics on the model substrate before and after washing. Also, a clear improvement in the removal potential means, for example, that the removal potential in the examples is improved by one rank or more compared to when only component (A) is used, and as the absolute level of the removal potential, it reaches rank A or B (removal rate of 50% or more). The nonionic surfactant of component (A) has an HLB of 13 or more, preferably 14 or more, from the viewpoint of ensuring water solubility.

[0012] From the viewpoint of an HLB of 13 or more, the average number of added moles of the polyoxyethylene (POE) group of component (A) is preferably 9 moles or more in (a1), 6 moles or more in (a2), and 7 moles or more in (a3). From the viewpoint of the makeup removal potential exhibited by component (A) alone, it is preferably 30 moles or less in (a1), 20 moles or less in (a2), and 40 moles or less in (a3), more preferably 20 moles or less in (a1), 10 moles or less in (a2), and 20 moles or less in (a3). Specifically, in (a1), POE(12) monolaurate, in (a2), POE(6)(caprylic / capric acid) glyceryl, POE(7)(caprylic / capric acid) glyceryl, and in (a3), POE(7) coconut oil fatty acid glyceryl, POE(8) coconut oil fatty acid glyceryl are preferred.

[0013] Component (A) can be used alone or in combination of two or more. When two or more nonionic surfactants are used, the HLB can be calculated by adding and averaging the HLB values of each nonionic surfactant species based on their content ratios, and this is taken as the mixed HLB. Even if the HLB of any of (a1), (a2), and (a3) is less than 13, if their mixed HLB is 13 or more, it corresponds to component (A) in the present invention. The content of component (A) is preferably 3% by mass or more, more preferably 5% by mass or more, still more preferably 10% by mass or more, preferably 30% by mass or less, more preferably 25% by mass or less, and still more preferably 20% by mass or less in the total composition from the viewpoints of detergency (removal potential), ease of removal from the skin, and the feeling of natural skin after removal. Further, the content of component (A) is preferably 3 to 30% by mass, more preferably 5 to 25% by mass, and still more preferably 10 to 20% by mass in the total composition.

[0014] Component (B) is a nonionic surfactant with an HLB of 10 or less selected from (b1), (b2), and (b3). (b1) Mono-fatty acid ester or ether of glycerin or diglycerin (b2) POE mono-fatty acid ester or POE glycerin mono-fatty acid ester having a POE group with an average addition mole number of 1 to 5 (b3) Sorbitan mono-fatty acid ester Component (B) is a lipophilic nonionic surfactant with a specific structure, which acts on a cosmetic coating film (such as a foundation film) formed by an oil-soluble silicone resin such as TMS to soften its hard surface. When combined with component (A), it dissolves in water and exhibits high detergency.

[0015] From the viewpoint of actively adsorbing onto the coating film surface from the aqueous solution to soften the coating film components in the combination with component (A), the nonionic surfactant of component (B) has an HLB of 10 or less, preferably 8 or less. As component (B), from the viewpoint that an appropriate amount can be stably solubilized by component (A), an HLB of 2 or more is preferred, and 4 or more is more preferred. Component (B), from the viewpoint of having an HLB of 10 or less, examples of (b1) include monoesters of oleic acid, stearic acid or isostearic acid with glycerin or diglycerin, or monoethers of oleyl alcohol, stearyl alcohol or isostearyl alcohol with glycerin or diglycerin. Examples of (b2) include POE monomyristate, POE monolaurate, POE glycerin monooleate, POE glycerin monostearate, POE glycerin monoisostearate, etc. which have a POE group with an average added mole number of 1 to 5. Further, examples of (b3) include sorbitan monostearate, sorbitan monooleate, sorbitan monoisostearate, etc. Among them, from the viewpoint of ensuring low-temperature stability, examples of (b1) include monoesters of oleic acid or isostearic acid with glycerin or diglycerin, or monoethers of oleyl alcohol or isostearyl alcohol with glycerin or diglycerin. Examples of (b2) include POE monolaurate, or POE glycerin monooleate or POE glycerin monoisostearate which have a POE group with an average added mole number of 1 to 5. Further, examples of (b3) include sorbitan monooleate, sorbitan monoisostearate, which are preferably used.

[0016] Component (B) can be used alone or in combination of two or more. Even if the HLB of any one of (b1), (b2) and (b3) exceeds 10, as long as their mixed HLB is 10 or less, it corresponds to component (B) in the present invention. From the viewpoint of being solubilized by component (A) and softening the coating film surface, the content of component (B) is preferably 0.3% by mass or more, more preferably 0.5% by mass or more, further preferably 1% by mass or more, 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. Also, the content of component (B) is preferably 0.3 to 10% by mass, more preferably 0.5 to 8% by mass, and further preferably 1 to 5% by mass in the total composition.

[0017] In the present invention, in order to enhance the makeup removal potential, the mass ratio (A) / (B) of component (A) to component (B) is important. From the viewpoint of solubilizing component (B) with low solubility in water with component (A) and improving the removal potential, (A) / (B) is 1 or more, preferably 1.5 or more, and more preferably 2 or more. Also, from the viewpoint of relatively increasing the amount of component (B) sufficiently to improve the removal potential, (A) / (B) is 25 or less, preferably 15 or less, and more preferably 10 or less. Also, the mass ratio (A) / (B) of component (A) to component (B) is 1 to 25, preferably 1.5 to 15, and more preferably 2 to 10.

[0018] Since the aqueous cleaning composition of the present invention is an aqueous solution of a nonionic surfactant, a harsh skin feeling like that of a facial cleanser cannot be obtained on the skin after rinsing. However, since it has the property of spontaneously mixing with water without the need to physically promote emulsification like oil, it can be quickly rinsed off. From the viewpoint of reducing stickiness when removing makeup from the skin while maintaining the makeup removal potential and obtaining a bare skin feeling of the skin after removal, the total content ((A)+(B)) of components (A) and (B) is preferably 5% by mass or more, more preferably 7% by mass or more in the total composition. Also, from the viewpoint of reducing the residual feeling on the skin after removal and effectively obtaining a bare skin feeling after removal, 25% by mass or less is preferable, and 20% by mass or less is more preferable. Also, the total content ((A)+(B)) of components (A) and (B) is preferably 5 to 25% by mass, more preferably 7 to 20% by mass in the total composition.

[0019] The polyol of component (C) promotes the dissolution of the nonionic surfactant in water and makes it easier to act on makeup. Such polyols are those used in ordinary detergent compositions, and examples thereof include ethylene glycol, diethylene glycol, hexylene glycol, polyethylene glycol with an average molecular weight of 1000 or less, propylene glycol, dipropylene glycol, polypropylene glycol with an average molecular weight of 1500 or less, 1,2-propanediol isoprene glycol, 1,3-butylene glycol, dibutylene glycol, glycerin, diglycerin, triglycerin, tetraglycerin, hexaglycerin, decaglycerin trimethylpropanol, and the like. Among these, those that generally raise the cloud point of POE-added nonionic surfactants, such as 1,3-butylene glycol, dibutylene glycol, 1,2-propanediol, etc., are preferably used from the viewpoint of increasing solubility and expanding the temperature range for maintaining transparency and uniformity.

[0020] The polyol of component (C) can be used alone or in combination of two or more. From the viewpoint of promoting the dissolution of components (A) and (B) and exerting detergency, the content is preferably 5% by mass or more, more preferably 10% by mass or more, still more preferably 20% by mass or more, preferably 50% by mass or less, more preferably 45% by mass or less, and still more preferably 40% by mass or less in the total composition. Also, the content of component (C) is preferably 5 to 50% by mass, more preferably 10 to 45% by mass, and still more preferably 20 to 40% by mass in the total composition.

[0021] In the present invention, the water of component (D) functions as a solvent. From the viewpoint of controlling the solubility of the surfactant together with component (C) and exerting detergency, the content is preferably 30% by mass or more, more preferably 40% by mass or more, still more preferably 50% by mass or more, preferably 80% by mass or less, more preferably 70% by mass or less, and still more preferably 60% by mass or less in the total composition. Also, the content of the water of component (D) is preferably 30 to 80% by mass, more preferably 40 to 70% by mass, and still more preferably 50 to 60% by mass in the total composition.

[0022] As described above, the polyol of component (C) has the role of extracting the removal potential for makeup while controlling the solubility of components (A) and (B). However, if the amount is too small, there is a risk that the detergency of the surfactant cannot be sufficiently exerted, and if it is too large, conversely, the detergency may be impaired. Therefore, the balance between the polyol of component (C) and the water of component (D) is important. From the viewpoint of sufficiently extracting the removal potential, the mass ratio (C) / (D) of component (C) to component (D) is preferably 0.1 or more, more preferably 0.25 or more. Also, from the viewpoint of avoiding the critical micelle concentration (CMC) becoming infinitely large and suppressing the separation of the lipophilic nonionic surfactant of component (B) due to the interaction with the hydrophilic nonionic surfactant of component (A) being cut off, it is preferably 1.3 or less, more preferably 1.25 or less. Also, the mass ratio (C) / (D) of component (C) to component (D) is preferably from 0.1 to 1.3, more preferably from 0.25 to 1.25.

[0023] In the present invention, from the viewpoints of removability such as rinsability and the feeling of bare skin after removal, 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.

[0024] The aqueous cleaning composition of the present invention can further contain one or more selected from (E) amphoteric surfactants and anionic surfactants. In this case, removability such as rinsability and the feeling of bare skin can be further enhanced. Also, when filled in a foam discharge container for use, the foam quality can be improved. Examples of the amphoteric surfactant include those used in ordinary detergent compositions, such as alkyl sulfobetaine, alkyl hydroxy sulfobetaine, alkyl carbobetaine, alkyl amide hydroxy sulfobetaine, alkyl amide amine type betaine, alkyl imidazoline type betaine, etc. Here, the number of carbon atoms in the alkyl group of the amphoteric surfactant is preferably 8 to 20, more preferably 8 to 14. Among these, from the viewpoints of removability such as ease of rinsing and foam quality, the amphoteric surfactant is more preferably one or more selected from alkyl amide propyl betaine and alkyl hydroxy sulfobetaine having an alkyl group with 8 to 14 carbon atoms, still more preferably alkyl hydroxy sulfobetaine, and even more preferably lauryl hydroxy sulfobetaine.

[0025] One or more amphoteric surfactants can be used in combination. From the viewpoint of maintaining the detergency while improving the feeling of the skin after washing, the content is preferably 0.5% by mass or more, more preferably 1% by mass or more in the total composition, and preferably 4% by mass or less, more preferably 3% by mass or less from the viewpoint of maintaining the detergency.

[0026] Examples of the anionic surfactant include those used in ordinary detergent compositions without limitation, such as carboxylic acid-based surfactants such as fatty acid salts, alkyl ether carboxylates, polyoxyethylene alkyl ether carboxylates; sulfuric acid esters such as alkyl sulfates, alkyl ether sulfates, polyoxyethylene alkyl ether sulfates; sulfonates such as alkyl sulfosuccinate salts, polyoxyalkylene alkyl sulfosuccinate salts, α-olefin sulfonates, hydroxyalkane sulfonates; N-acyl amino acid salts, N-acyl alkyl taurine salts, POE phosphates, etc. Among these, from the viewpoints of foaming and ensuring stability at low temperatures, it is preferable to contain at least one selected from POE lauryl ether carboxylate, POE lauryl ether sulfate, and POE phosphate.

[0027] The anionic surfactant can be used alone or in combination of two or more kinds, and the content is preferably 0.2% by mass or more, more preferably 0.5% by mass or more, in the whole composition from the viewpoint of maintaining detergency while improving the feeling of bare skin, and preferably 2% by mass or less, more preferably 1% by mass or less from the viewpoint of maintaining detergency.

[0028] Component (E) can be used alone or in combination of two or more kinds, and can be used in combination with an amphoteric surfactant and an anionic surfactant. The content of component (E) is preferably 0.2% by mass or more, more preferably 0.5% by mass or more, preferably 4% by mass or less, more preferably 3% by mass or less in the whole composition from the viewpoint of maintaining detergency while improving the feeling of bare skin. Also, the content of component (E) is preferably 0.2 to 4% by mass, more preferably 0.5 to 3% by mass in the whole composition from the viewpoint of maintaining detergency.

[0029] In the present invention, the mass ratio (E) / ((A)+(B)) of component (E) to the total content of components (A) and (B) is preferably 0.03 or more from the viewpoints of removability such as rinsability and enhancing the feeling of bare skin. On the other hand, from the viewpoint of avoiding the addition of a surfactant having a charge from hydrophilically changing the HLB of the system, thereby reducing the action efficiency on makeup which is an oily stain and affecting the makeup removal rate, (E) / ((A)+(B)) is more preferably 0.15 or less. Also, the mass ratio (E) / ((A)+(B)) of component (E) to the total content of components (A) and (B) is preferably 0.03 to 0.15.

[0030] The aqueous detergent composition of the present invention can further contain an oily component (including a fragrance) other than component (B) within a range that does not impair detergency and transparency. The content of the oily component (including a fragrance) other than component (B) is preferably 0.3% by mass or less, more preferably 0.2% by mass or less in the whole composition from the viewpoint of ease of removal from the skin. From the same viewpoint, the content of the component other than the fragrance among the oily components other than component (B) is preferably 0.1% by mass or less, more preferably 0.01% by mass or less in the whole composition.

[0031] In addition to the above components, the aqueous cleaning composition of the present invention can further contain components used in ordinary cleaning compositions. For example, surfactants other than the above; lower alcohols such as ethanol and isopropyl alcohol; aromatic alcohols such as benzyl alcohol and benzyloxyethanol; cellosolves such as ethyl cellosolve and butyl cellosolve; carbitols such as ethyl carbitol and butyl carbitol; moisturizing components such as sugars (derivatives), amino acids (derivatives), animal and plant (protein) derivatives, and animal and plant extracts; silicone derivatives such as polyoxyalkylene-modified silicones; high molecular compounds; inorganic or organic salts such as sodium sulfate, sodium carbonate, sodium hydrogen carbonate, 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 isopropylmethylphenol; preservatives, sequestering agents, antioxidants, ultraviolet absorbers, fragrances, vitamins, natural pigments, coloring agents such as tar pigments, and the like can be mentioned.

[0032] The aqueous cleaning composition of the present invention is preferably liquid at 25°C. By "liquid", it means the property that when it is put on the palm, it has no shape-retaining property and spreads immediately, and usually, if the viscosity at 25°C is about 3000 mPa·s or less, it shows such behavior. On the other hand, a lower viscosity is advantageous in terms of spreading on the skin and being compatible with makeup, and shortening the time of rubbing the skin. From that point, the viscosity of the aqueous cleaning composition at 25°C is preferably 100 mPa·s or less, more preferably 50 mPa·s or less, and even more preferably 30 mPa·s or less. In the present invention, the viscosity of the aqueous cleaning composition is measured at 25°C for 1 minute using a B-type viscometer (TVB-10 type viscometer, manufactured by Toki Sangyo Co., Ltd.). Viscosities less than 100 mPa·s are measured at a rotor No. 1 (rotation speed) of 60 rpm, viscosities of 100 to 199 mPa·s are measured at a rotor No. 1 (rotation speed) of 30 rpm, viscosities of 200 to 499 mPa·s are measured at a rotor No. 1 (rotation speed) of 12 rpm, and viscosities of 1000 mPa·s or more are measured at a rotor No. 2 (rotation speed) of 12 rpm.

[0033] Since the aqueous cleaning composition of the present invention is aqueous (water-based), it can be easily mixed with water, is not sticky, and can be easily washed away, and has a high feeling of natural skin after being washed away. Furthermore, if it is liquid (low viscosity) as described above, these effects can be improved, it spreads easily on the skin, and the detergency is quickly exhibited. Also, it can be easily impregnated into sheets and cotton pads for makeup, and can be used by wiping. Particularly, from the viewpoint of being easily impregnated into sheets and cotton pads for makeup when used by wiping and excellent dischargeability when filled in a foam discharge container, the viscosity of the aqueous cleaning composition at 25°C is preferably 30 mPa·s or less.

[0034] The aqueous cleaning composition of the present invention can be produced by first mixing (B) a lipophilic nonionic surfactant with (A) a hydrophilic nonionic surfactant, and then adding (C) a polyol and (D) water and uniformly mixing them. Component (E) can be appropriately added after preparing the aqueous solution. The aqueous cleaning composition of the present invention is preferably a transparent single-phase liquid at 25°C. Here, a transparent single-phase liquid means having a transparent appearance without separation, which means that each component is uniformly mutually dissolved. In such a state, due to the interaction of the nonionic surfactants of components (A) and (B), the potential for removing makeup is increased, the removability from the skin such as washability is excellent, and it can wash the skin to a high natural skin feeling. Also, when the surfactant forms a higher-order association structure, the appearance may become semi-transparent, but in this case, it is also judged as a single phase. When the system separates into two phases, the appearance becomes white and turbid or in a two-layer state, and it becomes difficult to obtain the above various performances as designed.

[0035] Since the aqueous cleaning composition of the present invention is mainly an aqueous solution containing a nonionic surfactant as a cleaning base, it is difficult to directly pick it up by hand and foam it for use. However, for example, by putting it in a foam discharge container and discharging it, it can be forced to form foam. By forming foam, not only is there the convenience of being able to apply it evenly to the skin while maintaining its shape, but there is also the advantage that the removability of makeup is further improved by applying it on the skin with foam. That is, although it does not naturally form foam, the foam formed from the nonionic surfactant aqueous solution that is forced to foam breaks instantly upon encountering dirt. At that time, the interfacial energy of the foam is converted into physical force and acts on the surface of the makeup coating film. In particular, in the aqueous cleaning composition having a high removal potential of the present invention, even the fine energy acting on the skin surface is observed as a difference in makeup removability.

[0036] From the viewpoints of ease of use and detergency, the aqueous cleaning composition of the present invention is preferably applied to the skin in a foamed state. From that viewpoint, it is preferably provided as a cleaning agent filled in an aerosol-type or non-aerosol-type foam discharge container. As the foam discharge container, any container can be used as long as it can mix the cleaning composition with air and discharge it as foam. However, a non-aerosol-type former container is preferable from the viewpoints of convenience in the environment of use for removing makeup and ease of disposal. For example, a pump former container that discharges by pressing a pump head and a squeeze former container that discharges by pressing the body part can be mentioned. Specifically, former containers manufactured by Yoshino Kogyosho Co., Ltd., Daiwa Can Co., Ltd., etc. can be mentioned. Also, for example, former containers equipped with a foaming mechanism described in JP-A-7-315463, JP-A-8-230961, JP-A-2005-193972, JP-A-2019-107644, etc. can also be used. From the viewpoint of obtaining thick and elastic foam, a pump former container that discharges by pressing a pump head is preferable. Among them, it is preferable to use a pump-former container having a gas-liquid mixing mechanism described in JP-A-2019-107644 because it has higher foaming performance and a wider tolerance for the viscosity and properties of the solution. That is, as described in claim 1 of the same publication, the gas-liquid mixing mechanism has a liquid flow path through which the liquid supplied from the liquid supply unit to the mixing unit passes, and a gas flow path through which the gas supplied from the gas supply unit to the mixing unit passes. The liquid flow path includes an adjacent liquid flow path having a liquid inlet that opens to the mixing unit, and the gas flow path includes a plurality of adjacent gas flow paths each having a gas inlet that opens to the mixing unit. The liquid inlet is preferably arranged at a position corresponding to the confluence of the gases supplied to the mixing unit through the gas inlet from the plurality of adjacent gas flow paths. The pump-former container is likely to be affected by the viscosity of the content in terms of foam quality and pressing pressure during use. In order to ensure that it can be discharged as foam within the daily temperature range and with a reasonable pressing pressure, the viscosity of the aqueous cleaning agent composition of the content is preferably 50 mPa·s or less at 25°C. However, when the foaming property of the solution itself is low as in the present invention, it is more preferably 30 mPa·s or less.

[0037] The aqueous cleaning agent composition of the present invention is preferably filled in a foam discharge container and provided as a foam type. In other words, it is preferably used in a cleaning agent comprising the aqueous cleaning agent composition and a foam discharge container for containing the same. In addition, the aqueous cleaning agent composition of the present invention is also suitable for impregnating a sheet or cotton for makeup, applying it to the skin, and wiping off makeup or the like. After applying the aqueous cleaning agent composition to the skin, it may be wiped off together with makeup or the like using a sheet or cotton for makeup. The aqueous cleaning agent composition of the present invention is preferably used for skin cleaning, and particularly preferably used as a facial cleanser or makeup remover.
