Description

Technical Field

[0001] The present invention relates to cleaning compositions. Background Art

[0002] Oil-based cleansers are widely accepted in the market as cleansers with high cleansing power. Oil-based cleansers are preparations that combine oil agents that exert cleansing power with surfactants that emulsify and rinse the oil agents. Many studies have been conducted to improve the unique feel of oil agents and the reduction in cleansing power caused by mixing with water.

[0003] For example, Patent Document 1 describes an oily cleansing cosmetic containing di-branched fatty acid polyethylene glycol, oil and water, which has excellent refreshing feeling, cleansing effect, ease of makeup removal, ease of application and storage stability.

[0004] Patent Document 2 describes a transparent liquid oily composition containing three nonionic surfactants in a specific range of IOB, which can be used as a cleansing cosmetic in an environment where water is present, such as a bathroom or a washstand.

[0011] Figure 1 This is a diagram showing a vinyl chloride sheet used to evaluate the removability of makeup embedded in deep holes in Examples. DETAILED DESCRIPTION

[0012] In recent years, in the face of global warming and the prevalence of infectious diseases, high-durability makeup that is not easy to fall off has begun to be favored. Among long-lasting makeup cosmetics, for example, oil-soluble silicone resins such as trimethylsiloxysilicate (TMS) are combined to form a harder hydrophobic makeup film on the skin surface, which is not only resistant to sweat and sebum, but also physically prevents makeup from coming off. On the other hand, regarding makeup removers, awareness of not wanting to rub the skin has increased, and user behavior has changed in the direction of short-time, low-friction. In this situation, even with so-called high-cleansing oil-type makeup removers, there are still cases where makeup is not completely removed and remains in the recessed parts of the facial structure such as the eyes or nose, or in the pores, which has become one of the points of dissatisfaction for users.

[0013] Thus, in the conventional compositions, it is difficult to completely remove the dirt that is difficult to remove, such as cosmetics containing a film-forming agent such as a long-lasting foundation, from the facial surface having various sizes of unevenness by a small physical force.

[0014] The reason why makeup in the sunken areas that cannot be reached by human hands is not completely removed is that the makeup removers used so far are based on the premise that makeup and preparations are fully mixed by physical force before washing. Therefore, the current practice of not rubbing the skin will cause disadvantages from the perspective of mixing preparations and makeup, and washing the preparations when the makeup has not yet fully floated will cause so-called functional incompleteness. In other words, the more you want to remove makeup without rubbing the skin, the more you will feel new anxiety or pressure such as makeup residue.

[0015] The present invention provides a composition that can remove makeup from fine depressions such as pores by simply applying to the skin and rinsing off dirt that is difficult to remove, such as foundation containing a film-forming agent, by using a nonionic surfactant containing a specific multi-chain type and adjusted to a specific HLB, a low-viscosity oil, and a specific aqueous component in combination.

[0016] The cleansing composition of the present invention can remove dirt that is difficult to remove, such as foundation containing a film-forming agent, from small depressions such as pores, even without applying physical force, simply by applying the preparation, spreading it, and rinsing it off. According to the present invention, the user no longer needs to blend the cleansing composition with the makeup, and even without rubbing the skin, the foundation in the pores can be completely removed.

[0017] Component (A) contains (a1) a multi-chain nonionic surfactant having at least one of two or more unsaturated chain hydrocarbon groups and saturated branched chain hydrocarbon groups, and the HLB value (mixed HLB value when containing two or more nonionic surfactants) is adjusted to a nonionic surfactant of 9.5 to 12.5.

[0018] Here, the HLB value is an index showing the hydrophilicity-lipophilicity balance (Hydrophile Lipophile Balance), and is obtained by the following formula of Griffin in this specification.

[0019]

[0020] When two or more nonionic surfactants are contained, the HLB value of the mixed surfactant is obtained by arithmetically averaging the HLB values ​​of the respective nonionic surfactants according to their mass ratios.

[0021] Mixed HLB = Σ(HLB X ×W X ) / ΣW X

[0022] HLB X It represents the HLB value of nonionic surfactant X.

[0023] W X Indicates HLB X The mass (g) of the nonionic surfactant X.

[0024] The multi-chain nonionic surfactant of component (a1) having at least two selected from unsaturated chain hydrocarbon groups and saturated branched chain hydrocarbon groups is dissolved in the oily agent, penetrates into the makeup film in the pores and other recesses together with the oily agent, and pulls dirt away from the skin or the base and disperses it in the water during rinsing.

[0025] The unsaturated chain hydrocarbon group is preferably a hydrocarbon group having 8 to 22 carbon atoms, more preferably a straight-chain hydrocarbon group having 12 to 18 carbon atoms, and still more preferably an oleyl group. The saturated branched chain hydrocarbon group is preferably a hydrocarbon group having 8 to 22 carbon atoms, more preferably a hydrocarbon group having 12 to 18 carbon atoms, and still more preferably an isostearyl group.

[0026] From the viewpoint of being soluble in oily agents and spontaneously penetrating into oily dirt such as makeup, it is important that component (a1) has lipophilic properties. On the other hand, from the viewpoint of being able to be spontaneously dispersed and washed away simply by contact with water without rubbing, it is also necessary to have moderate hydrophilicity. In order to exhibit the former property, a structure having a plurality of long-chain alkyl groups is more advantageous. From the viewpoint of the latter, in order to exhibit affinity when in contact with water, it is preferably selected from those with a high HLB value.

[0027] Therefore, the HLB value of the multi-chain nonionic surfactant of the component (a1) is preferably 7-13, more preferably 8-12.

[0028] In addition, component (a1) is preferably selected from POE sorbitan fatty acid esters, POE sorbitol fatty acid esters, POE glyceryl ether fatty acid esters, and POE fatty acid esters having 2 to 4 oleyl groups or isostearyl groups in view of high versatility and easy availability.

[0029] The nonionic surfactant of the component (A) may be combined with a nonionic surfactant other than the component (a1).

[0030] The nonionic surfactant combined with component (a1) is not limited. For example, one or a combination of two or more of glycerol fatty acid esters, diglycerol fatty acid esters, polyglycerol fatty acid esters, sorbitan fatty acid esters, alkyl glyceryl ethers, POE alkyl ethers, POE sorbitan fatty acid esters, POE glycerol ether fatty acid esters, POE fatty acid esters, alkyl glucoside, etc. can be used.

[0031] When these are used, the HLB value (mixed HLB value) is adjusted to 9.5 to 12.5 in combination with component (a1). If it is less than 9.5, the dispersibility in water is poor and the makeup is likely to remain, while if it exceeds 12.5, the permeability of the makeup is poor, so the makeup is likely to remain in the depressions.

[0032] As component (A), in addition to component (a1), a single-chain nonionic surfactant having one chain hydrocarbon group is preferably used. Multi-chain nonionic surfactants such as component (a1) are generally not easily soluble in water, and they temporarily increase viscosity due to mixing with a small amount of water. Therefore, a certain degree of time is required to be completely removed when contacting a water flow. Here, if a single-chain nonionic surfactant is used in combination, the aggregation of nonionic surfactants is suppressed, and the dispersibility of makeup can be improved. The so-called improvement of the dispersibility of makeup refers to improving the removability of makeup that has sunk into deep pores, removing it in a short time during washing, or both.

[0033] As the single-chain nonionic surfactant, one or a combination of two or more selected from the following (a2) and (a3) ​​is preferred, and a combination of (a2) and (a3) ​​is more preferred.

[0034] (a2) a single-chain nonionic surfactant having an HLB value of 11 to 18 and having one chain hydrocarbon group;

[0035] (a3) A single-chain nonionic surfactant having an HLB value of 3 to 10 and having one chain hydrocarbon group.

[0036] As component (a2), for example, POE fatty acid ester, POE alkyl ether, POE sorbitan fatty acid ester, POE glyceryl ether fatty acid ester, polyglycerol fatty acid ester, alkyl glucoside, etc. The single-chain nonionic surfactant of component (a2) is preferably a short-chain one having a hydrocarbon group with 8 to 14 carbon atoms from the viewpoint of suppressing temporary viscosity increase of component (a1) caused by mixing with water during rinsing and promoting dispersion in water.

[0037] Moreover, as a component (a3), a single-chain type glyceryl fatty acid ester, a diglyceryl fatty acid ester, an alkyl glyceryl ether, a sorbitan fatty acid ester etc. are mentioned, for example.

[0038] The single-chain nonionic surfactant of component (a3) ​​is preferably selected from oleic acid, isostearic acid, glycerol fatty acid esters, diglycerol fatty acid esters, glycerol ethers, sorbitan fatty acid esters, etc., from the viewpoint of stably dissolving component (a2) in the oil phase.

[0039] From the viewpoint of improving dispersibility during rinsing, component (A) preferably contains component (a1) and one or more selected from components (a2) and (a3), and more preferably uses components (a1), (a2) and (a3) ​​in combination.

[0040] When components (a1), (a2) and (a3) ​​are used in combination, the mass ratio (a1) / [(a2)+(a3)] of component (a1) to the total amount of components (a2) and (a3) ​​is preferably 0.2 or more, more preferably 0.5 or more, preferably 5 or less, more preferably 4.5 or less, and even more preferably 4 or less, from the viewpoint of improving the dispersibility of makeup. In addition, the mass ratio (a1) / [(a2)+(a3)] of component (a1) to the total amount of components (a2) and (a3) ​​is preferably 0.2 to 5, more preferably 0.2 to 4.5, and even more preferably 0.5 to 4.

[0041] In addition, when the cleaning composition is filled in a container with a spray dispenser to prepare a spray-type cleaning composition, since the viscosity of the cleaning composition must be controlled to be low, the mass ratio (a1) / [(a2)+(a3)] of the component (a1) to the total amount of the components (a2) and (a3) ​​is preferably 0.3 or more, more preferably 0.4 or more, and preferably 1 or less, more preferably 0.8 or less from the viewpoint of low viscosity. In addition, the mass ratio (a1) / [(a2)+(a3)] of the component (a1) to the total amount of the components (a2) and (a3) ​​is preferably 0.3 to 1, more preferably 0.4 to 0.8.

[0042] The content of component (A) is 7% by mass or more, preferably 10% by mass or more, in the total composition from the viewpoint of exerting good makeup removal performance (performance of washing away makeup from the skin or base); from the viewpoint of the penetration effect into the concave (the effect of deeply penetrating makeup that has entered the concave), it is 35% by mass or less, preferably 25% by mass or less. In addition, the content of component (A) is 7 to 35% by mass, preferably 10 to 25% by mass in the total composition.

[0043] Component (B) is an oil phase having a viscosity at 25°C of 11 mPa·s or less.

[0044] The oil phase of component (B) plays the role of dissolving the oil-soluble polymer that forms a relatively hard film on the surface of the foundation film and infiltrating it into the film to soften the film itself; and of allowing component (A) to quickly penetrate into the structure such as depressions. From this point of view, the viscosity at 25°C is adjusted to be 11 mPa·s or less.

[0045] Here, the viscosity is measured using a B-type viscometer (TVB-10 type viscometer, manufactured by Toki Sangyo Co., Ltd.), and the viscosity of less than 100 mPa·s at 25°C is measured by using a rotor No. 1 (rotation number) of 60 rpm for a measurement time of 1 minute. The viscosity of 100 to 199 mPa·s is measured by using a rotor No. 1 (rotation number) of 30 rpm, and the viscosity of 200 to 499 mPa·s is measured by using a rotor No. 1 (rotation number) of 12 rpm.

[0046] The oily agent constituting the oil phase of component (B) may be any liquid oil generally used in cosmetics, and examples thereof include hydrocarbon oils such as isododecane, isohexadecane, light liquid isoparaffin, liquid isoparaffin, and liquid paraffin; ether oils such as dioctyl ether and alkyl-1,3-dimethylbutyl ether; monoester oils such as cetyl 2-ethylhexanoate, cetyl octanoate, isononyl isononanoate, isotridecyl isononanoate, hexyl laurate, isopropyl myristate, octyldodecyl myristate, myristyl myristate, 2-hexyldecyl myristate, isopropyl palmitate, and octyl palmitate; diester oils such as propylene glycol dicaprylate and neopentyl glycol dicaprylate; triester oils such as tri(caprylic acid / capric acid)glyceryl, trioleic acid glyceryl, and tri-2-ethylhexanoin; and vegetable oils such as olive oil and jojoba oil.

[0047] The lower the viscosity of the oil phase of component (B), the higher the performance is from the viewpoint of solubility and permeability of the coating film. The viscosity of the oil phase is 11 mPa·s or less, preferably 10 mPa·s or less, and more preferably 8 mPa·s or less at 25°C.

[0048] When the detergent composition is filled in a container having a spray dispenser to prepare a spray type, the viscosity of the oil phase of component (B) is preferably 10 mPa·s or less, more preferably 8 mPa·s or less at 25° C. from the viewpoint of reducing the viscosity.

[0049] As component (B), an oily agent may be used alone, but it is preferred to use an oily agent (b1) having a viscosity of 8 mPa·s or less at 25° C. to adjust the viscosity. Such an oily agent has high coating film solubility and permeability. For example, even when combined with an oily agent having a viscosity of 12 mPa·s or more, the foundation that has penetrated deep into the depressions can be removed by adjusting the viscosity with these combinations.

[0050] Examples of the oil (b1) include isododecane, isohexadecane, hydrogenated polyisobutene having a viscosity of 8 mPa·s or less, light liquid isoparaffins, isononyl isononanoate, and isopropyl myristate.

[0051] The oil agent (b1) is contained in the oil phase of the component (B) in an amount of preferably 40% by mass or more, more preferably 50% by mass or more, and even more preferably 75% by mass or more.

[0052] Even if the viscosity of the entire oil phase is the same, a large amount of a low-viscosity oil such as (b1) can provide excellent removability from deeper recesses.

[0053] The content of component (B) is 60% by mass or more, preferably 65% ​​by mass or more, and 90% by mass or less, preferably 85% by mass or less, and more preferably 80% by mass or less in the total composition from the viewpoint of excellent dissolution and permeability of the coating film and good rinsing properties of makeup during rinsing. In addition, the content of component (B) is 60 to 90% by mass, preferably 60 to 85% by mass, and more preferably 65 to 80% by mass in the total composition.

[0054] Component (C) is one or more selected from water, alcohols having 2 to 3 carbon atoms, and diols. Component (C) improves the solubility stability of component (A) in the system and activates the surfactant function to promote penetration and dispersion into the foundation coating film.

[0055] Examples of the alcohol having 2 to 3 carbon atoms include ethanol and isopropanol.

[0056] Examples of the diol include dipropylene glycol, butylene glycol, and propylene glycol.

[0057] As the component (C), water, ethanol, 1,3-butylene glycol, and dipropylene glycol are preferred.

[0058] Component (C) can be used alone or in combination of two or more. From the viewpoint of the removal of makeup that has entered the recesses, the content is 0.05% by mass or more, preferably 0.5% by mass or more in the total composition, and from the viewpoint of the cleaning property and uniformity, it is 8% by mass or less, preferably 7% by mass or less. In addition, the content of component (C) is 0.05 to 8% by mass, preferably 0.05 to 7% by mass in the total composition.

[0059] In addition, when the cleaning composition is filled in a container with a spray dispenser to form a spray-type cleaning composition, the content of component (C) is preferably 0.05% by mass or more, more preferably 0.5% by mass or more, in the total composition from the viewpoint of dissolution stability, and is preferably 5% by mass or less, more preferably 4% by mass or less from the viewpoint of maintaining low viscosity at low temperatures. In addition, when the cleaning composition is filled in a container with a spray dispenser to form a spray-type cleaning composition, the content of component (C) is preferably 0.05 to 5% by mass, more preferably 0.5 to 4% by mass in the total composition.

[0060] In the present invention, the mass ratio (C) / (A) of component (C) to component (A) is preferably 0.03 to 0.4, more preferably 0.05 to 0.3, from the viewpoint of the permeability of component (A) to the coating film and the dispersibility during rinsing.

[0061] The cleaning composition of the present invention may further contain, in addition to the above-mentioned components, components commonly used in cleaning compositions, such as surfactants other than component (A), oily components other than component (B), polymer compounds, ultraviolet absorbers, antioxidants, fragrances, bactericides, preservatives, antifouling agents, etc.

[0062] The cleaning composition of the present invention can be produced by mixing and stirring the components by a common method.

[0063] The cleaning composition of the present invention is a liquid oil preparation, preferably a single liquid phase. The so-called liquid state means that it is easy to overflow when placed in the palm of the hand and tilted; the so-called single liquid phase means that it has a transparent to translucent appearance and has no obvious interface in the system.

[0064] The mechanism of action of general makeup remover oil includes: the process in which the composition dissolves the firm surface composed of oil-soluble polymers (such as trimethylsiloxysilicic acid) that form a durable makeup film through physical force such as blending with fingers, so that the makeup floats up; and the process in which the surfactant emulsifies the oil agent in which the makeup is dispersed by mixing with water by hand during washing, so that the oil agent is pulled away from the skin. In other words, the physical force of human hands is required to dissolve and disperse the makeup film or to emulsify and rinse the cleanser.

[0065] The cleansing composition of the present invention is a combination of components (A), (B) and (C). When the cleansing composition is dropped and placed on a foundation coating film or the like, the cleansing composition spontaneously penetrates into the coating film even without physical force, and even when the cleansing composition is merely exposed to a stream of water without being rubbed, the makeup can be dispersed and washed away from small recesses such as pores.

[0066] The cleansing composition of the present invention can be provided in a container with a pump dispenser, similar to a conventional oil-type makeup remover. In this case, since it is difficult to apply to the face without touching the hands, it can be taken from the palm of the hand and appropriately applied and spread, and then directly sprayed with water using a shower or the like to remove the makeup on the skin from the pores and other recesses.

[0067] In addition, the cleansing composition of the present invention can be filled in a container with a spray dispenser or an aerosol container, so that the preparation can be sprayed directly onto the skin, and makeup can be completely removed without almost contacting the skin.

[0068] When the detergent composition is filled in a container with a spray dispenser to prepare a spray type, the viscosity of the detergent composition is preferably adjusted to 30 mPa·s or less at 25°C from the viewpoint of expellability; and more preferably adjusted to 30 mPa·s or less at 7°C when it is intended to be used in winter. In addition, in this specification, the so-called "expellability" means that the preparation is expelled in the form of fine particles.

[0069] The cleaning composition of the present invention is preferably used for removing oily dirt from hydrophobic surfaces (surfaces such as human skin and clothes, or hard surfaces), preferably used for skin cleansing, and particularly preferably used as a facial cleanser, makeup remover, or whole body cleanser for removing oily dirt such as sunscreen.

[0098] [Example]

[0099] [Test Example 1]

[0100] The cleansing composition (Example A) and a commercially available cleansing agent (Biore Deep Cleansing Oil, manufactured by Kao Corporation) with the composition shown in Table 1 were evaluated for the removability of makeup embedded in deep pores and the removability of makeup on a dummy sheet. The results are shown in Table 1.

[0101] (Manufacturing method)

[0102] Component (A) was measured and mixed thoroughly when two or more components were used. Then, component (B) was added while stirring, and finally component (C) was added dropwise and stirred until the mixture was homogenized to obtain a cleaning composition (Example A).

[0103] (Evaluation method)

[0104] (1) Removal of makeup stuck in deep pores:

[0105] This method is to fill intentionally created fine depressions with foundation to form a thick foundation coating film, let the preparation act, and then rinse it off. This method can strongly reflect the high penetration of the cleanser composition into the depressions, so the removal performance of the foundation in the depth direction that has entered the depression can be measured.

[0106] right Figure 1 As shown, a sheet-like base made of vinyl chloride (manufactured by Komatsu Ltd.) has 61 holes with a diameter of 0.5 mm and a depth of 0.5 mm evenly arranged within a circular range of 32 mm in diameter. A highly durable foundation (Revlon COLORSTAY Long-Lasting Liquid Foundation) is applied in such a way as to fill the holes, and after the makeup overflowing from the surface is evenly scraped off, it is allowed to dry for more than 3 hours.

[0107] 0.5 mL of each cleaning composition was dropped onto the substrate, left for 1 minute, and then directly rinsed with shower water for 20 seconds. After drying, the substrate was magnified and observed by DSA, and the degree of removal of the foundation in the pores was evaluated according to the following criteria.

[0108] In addition, this evaluation is considered to be acceptable if it is "3" or higher.

[0109] 1: The shape of the foundation in the hole does not change at all.

[0110] 2: The shape of the foundation in the pores is slightly removed compared to before application.

[0111] 3: Compared to before application, the shape of the foundation in the pores is obviously removed.

[0112] 4: The foundation in the hole is removed until the hole shape of the base can be confirmed.

[0113] 5: The foundation in the hole is removed to expose the base.

[0114] (2) Removability of makeup on model sheets:

[0115] A method of making a normal amount of foundation film on a model sheet with fine irregularities similar to the irregularities of actual skin, and comprehensively measuring its removability. This method can evaluate the removability and washability of foundation that is suitable for actual use.

[0116] In a molded piece with fine depressions such as pores (manufactured by OKAMOTO Chemicals, artificial leather, LAFORET white), 10×5 cm 2 Within the range of , apply 0.045g of a long-lasting foundation (Revlon COLORSTAY long-lasting liquid foundation) and dry for more than 1 hour.

[0117] Cut the foundation application area into 2 x 2.5 cm pieces 2 A small piece of was used as a test piece.

[0118] One drop of each cleanser composition was dropped onto the test piece with a dropper and left to stand for 1 minute. After that, the test piece was rinsed with a shower for a predetermined time (described in the table) and dried, and then the removal of the foundation was evaluated visually according to the following criteria.

[0119] In addition, this evaluation is considered to be acceptable if it is "A", "B" or "C".

[0120] E: There is no change in the coating film of the foundation.

[0121] D: The coating film of the foundation was slightly removed, but most of it remained. C: The coating film of the foundation was obviously removed.

[0122] B: The coating film of the foundation is almost removed.

[0123] A: The coating film of the foundation is completely removed.
