Description

Composition

The present invention relates to a composition.

In recent years, due to global warming and the need to wear masks amid the current epidemic, people have come to prefer makeup that is long-lasting and does not easily come off. On the other hand, when it comes to makeup removers, there is an increasing awareness that people do not want to rub their skin to avoid damaging it. Users who do not want to rub their skin are shifting their makeup removal behavior to short-time, low-friction methods. Under such circumstances, even oil-type makeup removers, which are said to have high cleansing power, may not completely remove makeup from the recesses of the face, such as around the eyes and nose, or in the pores, and this is one of the complaints of users. On the other hand, if you try to solve the problem of makeup not coming off completely, you need to take the time to massage every corner of your face to blend the makeup remover with the makeup, which is not only time-consuming but also causes friction on the skin, which is one of the complaints of users. In other words, it is thought that many people are dissatisfied with the dilemma between skin rubbing and makeup removal, and the effort required to remove makeup.

In this situation, several new compositions have been investigated with a view to reducing the number of times the composition needs to be blended.
For example, Patent Document 1 describes an emulsion-type cleansing cosmetic that contains a liquid hydrocarbon oil, two specific nonionic surfactants, an acylated amino acid surfactant, and water, and that quickly blends into makeup, has high cleansing power, and is stable over time.
Patent Document 2 describes a cleansing agent that contains a paraffin mixture having a specific boiling point range, a specific nonionic surfactant, and a dihydric alcohol, and that quickly blends with makeup stains, is easy to rinse off, leaves a refreshing feeling after rinsing, has an emollient feel after rinsing, and leaves the skin moisturized after rinsing.

Furthermore, new compositions have been proposed with a view to reducing friction on the skin during massage.
For example, Patent Document 3 describes an oil-based cleansing agent that contains a specific nonionic surfactant and oil, does not become low in viscosity, does not drip from the hands when used, has excellent usability as it is easy to apply to the desired area, spreads well during cleansing, has a good feel when used with a moderate thickness, can be used in environments where the hands and face are wet, such as in a bathroom or at a washstand, has high cleansing power, and does not leave a feeling of oil remaining after rinsing with water.

Detailed Description of the Invention

The cleansing cosmetics described in Patent Documents 1 and 2 quickly absorb makeup and can remove the makeup even with a small amount of massage as the agent and makeup mix together. However, they are based on the premise that a so-called blending step is necessary, and are unable to remove makeup from inside hard-to-reach pores or areas that the user has failed to massage, and so have not yet resolved users' dissatisfaction.
In addition, while the cleansing agent described in Patent Document 3 feels thick during cleansing and can reduce irritation to the skin and discomfort during use, it is premised on the premise that it will not come off unless the user massages it in, which is time-consuming, does not eliminate friction on the skin, and similarly cannot remove makeup from areas that the user fails to massage.
Therefore, there is a need for a composition that can thoroughly remove makeup without applying a physical force to blend the makeup remover with the skin makeup. This need to thoroughly remove dirt without applying a physical force is not limited to makeup removers, but is also applicable to other cleansing agents.

The inventors have discovered that a composition that combines a specific nonionic surfactant with a low-viscosity oil phase in a specific ratio can thoroughly remove oily stains such as cosmetics simply by coming into contact with the stains.

The composition of the present invention can thoroughly remove oily stains such as those from foundations that are difficult to remove, without applying unnecessary physical force.

The component (A) used in the present invention is at least one of the components (a1) to (a5) described above.
The polyoxyethylene alkyl ether of component (a1) has an alkyl group having 12 to 18 carbon atoms and an oxyethylene group having an added mole number of 3 to 12, and preferably has an alkyl group selected from a linear alkyl group having 12 to 16 carbon atoms, an unsaturated alkyl group having 18 carbon atoms, and a branched alkyl group having 12 to 18 carbon atoms.

The polyoxyethylene fatty acid ester of component (a2) has one alkyl group having 14 to 18 carbon atoms and an oxyethylene group having an added mole number of 3 to 5 or 7 to 9, or has one alkyl group having 12 to 16 carbon atoms and an oxyethylene group having an added mole number of 10 to 12, or has two alkyl groups having 12 to 18 carbon atoms and an oxyethylene group having an added mole number of 3 to 12. Of those having two alkyl groups having 12 to 18 carbon atoms, those having an oxyethylene group having an added mole number of 5 to 12 are more preferred, and those having an oxyethylene group having an added mole number of 5 to 10 are even more preferred. Also, those having one or more linear alkyl groups having 12 carbon atoms or branched alkyl groups having 18 carbon atoms are preferred.

The polyoxyethylene glycerin fatty acid ester of component (a3) has one alkyl group with 12 to 18 carbon atoms and an added mole number of 6 or 10 to 30 oxyethylene groups, or has two to three alkyl groups with 12 to 18 carbon atoms and an added mole number of 6 to 30 oxyethylene groups, preferably a branched alkyl group with 18 carbon atoms.

The polyglycerol fatty acid ester of component (a4) has a linear alkyl group with 10 to 14 carbon atoms, and the ratio of the degree of polymerization of polyglycerol to the number of fatty acid bonds (= degree of polymerization of polyglycerol / number of fatty acid bonds) is 2 to 5.

The polyoxyethylene sorbitan fatty acid ester or polyoxyethylene sorbitol fatty acid ester of component (a5) is a polyoxyethylene sorbitan fatty acid ester or polyoxyethylene sorbitol fatty acid ester having three unsaturated chain alkyl groups and an added mole number of 20 to 40 oxyethylene groups, or having four unsaturated chain alkyl groups and an added mole number of 35 to 40 oxyethylene groups, or having three to four saturated branched chain alkyl groups and an added mole number of 20 to 40 oxyethylene groups, and preferably having an alkyl group with 18 carbon atoms.

The above nonionic surfactants have moderate solubility in water and oil, and do not dissolve too much in the rinse water or oil when rinsing with water (including hot water; the same applies below), so they act on the skin (target surface) and draw water between the dirt and the skin (target surface), separating the dirt from the skin and dispersing it in water. This is thought to be due to the fact that surface modification, which makes the target solid surface hydrophilic, promotes the water wettability of the target surface.

From the above viewpoint, the components (a1) to (a5) preferably have an HLB value of 7 to 14, and more preferably an HLB value of 7 to 12.9.
Here, the HLB value is an index showing the hydrophilic-lipophilic balance, and in this specification, is calculated by the following formula proposed by Griffin.

Component (A) may be one or a combination of two or more selected from (a1) to (a5), and the content in the composition is 5 to 50% by mass, preferably 9 to 40% by mass, and more preferably 10 to 30% by mass, from the viewpoint of obtaining good makeup dispersibility and cleaning power.

Component (B) is an oil phase having a viscosity of 15 mPa·s or less at 25°C.
Component (B) quickly dissolves the oil-soluble polymer that forms a hard film on the surface of the foundation coating, penetrating into the coating and softening the coating itself to impart fluidity, and also plays a role in delivering component (A) to the surface of the skin (base).

The oil that constitutes the oil phase of component (B) may be any liquid oil that is normally used in cosmetics, such as hydrocarbon oils such as isododecane, isohexadecane, light liquid isoparaffin, liquid isoparaffin, and liquid paraffin; ether oils such as dicaprylyl ether and alkyl-1,3-dimethylbutyl ether; cetyl 2-ethylhexanoate, cetyl octanoate, isononyl isononanoate, isotridecyl isononanoate, hexyl laurate, isopropyl myristate, octyldodecyl myristate, and myristyl ether. These include monoester oils such as myristyl phosphate, 2-hexyldecyl myristate, isopropyl palmitate, and octyl palmitate; diester oils such as propylene glycol dicaprylate and neopentyl glycol dicaprate; triester oils such as tri(caprylic/capric acid)glycerin, trioleate glycerin, and tri-2-ethylhexanoate glycerin; ether oils such as dicaprylyl ether and cetyl-1,3-dimethylbutyl ether; and vegetable oils such as olive oil and jojoba oil.

Component (B) can be used in combination of one or more oils. From the viewpoint of achieving both uniformity of the solution (transparency of the composition) and cleaning power, it is preferable to use two or more. When two or more oils are used in combination, the viscosity of the oil can be obtained by measuring the viscosity of the mixed oils.
The viscosity is measured, for example, using a Brookfield viscometer (Vismetron viscometer: Model VS-A1 (manufactured by Shibaura Systems Co., Ltd.) at spindle number 1, 60 rpm (revolutions per minute), and 60 seconds, or at spindle number 1, 30 rpm (revolutions per minute), and 60 seconds.
The content of component (B) in the composition is from 50 to 95% by mass, and preferably from 70 to 90% by mass, from the viewpoint of obtaining good detergency and dispersibility.

The composition used in the present invention may further contain, in addition to the above-mentioned components, components that are typically used in detergent compositions, such as surfactants other than component (A), polymeric compounds, powders, water, moisturizing agents, bactericides, alcohols, anti-inflammatory agents, preservatives, chelating agents, salts, pearlizing agents, fragrances, cooling agents, pigments, ultraviolet absorbing agents, antioxidants, plant extracts, etc.

The composition used in the present invention can be produced by mixing and stirring the components in a conventional manner, and can be used as a cleaning composition. The composition of the present invention can be preferably used as a cleaning agent for removing oily stains from solid surfaces (surfaces such as human skin or clothing, or hard surfaces), and is preferably used for skin cleaning, and is particularly preferably used as a whole body cleanser for removing oily stains such as face washes, makeup removers, and sunscreens.

The composition of the present invention can be brought into contact with cosmetics such as make-up and can remove the cosmetics without mixing the composition with the cosmetics.
The composition can be brought into contact with the cosmetic by, for example, filling a container with the composition and dripping it onto the cosmetic; taking an appropriate amount of the composition in the hand and placing it on the cosmetic; filling a mist dispenser or aerosol container with the composition and spraying it onto the cosmetic; or the like.

After contacting the composition with the cosmetics, if necessary, the cosmetics can be removed by leaving it to stand and then rinsing with water or hot water, such as from a shower. The mixture of the composition and cosmetics is transferred into the water with running water, and removed from the skin. The temperature of the water or hot water is, for example, 5 to 45°C. The time for leaving the composition to stand after contacting the cosmetics may be any time, for example, 10 seconds to 20 minutes, and is preferably 20 seconds to 3 minutes.

Conventionally, the mechanism of action of typical oil-type makeup removers for persistent makeup that is difficult to remove among the types of makeup (dirt) that they target consists of a process in which the composition dissolves the tough surface made of oil-soluble polymers (such as trimethylsiloxysilicate) that form a persistent makeup film by physical force, such as by rubbing the composition with a finger, thereby lifting the makeup, and a process in which the surfactant emulsifies the oil that disperses the makeup and removes it from the skin by mixing the composition with water by hand during rinsing. In other words, the involvement of physical force by human hands was required to dissolve and disperse the makeup film.
With this invention, simply by contacting the makeup, the product spontaneously penetrates the coating without the need for physical force, and when exposed to a stream of water, the makeup is dispersed and washed away through small depressions such as pores, without the need for rubbing.

In this way, with conventional oil-type makeup removers, after applying the composition to cosmetics such as makeup, it was necessary to apply physical force such as massaging or blending the composition with the cosmetics to mix them and transfer the cosmetics to the composition. However, with the present invention, it is possible to remove cosmetics without mixing the composition with the cosmetics.

Cleaning refers to removing dirt from a substrate (such as the surface of skin or clothing, or a hard surface) to which the dirt is attached. For example, in many cases, such as washing the body in a bathroom, washing clothes, and washing dishes, a detergent is used to wash the dirt, and then the dirt is finally removed by rinsing with water. Here, oily dirt that is low in water solubility and occurs in daily life, such as sebum and food oil (hereinafter, also simply referred to as dirt), is mainly removed using a composition consisting of a detergent surfactant and water. In this process, it is necessary to apply a detergent composition and apply physical force such as rubbing the skin with a towel, spinning clothes in a washing machine, or rubbing dishes with a sponge. In other words, physical force is required for cleaning.
Looking at the cleaning process in detail, it consists of three steps: (1) applying (contacting) the cleaning agent to the dirt, (2) applying physical force to transfer the dirt attached to the substrate into the cleaning solution, and (3) rinsing with water to remove the mixture of dirt and cleaning solution from the substrate. Since the dirt will not be detached from the substrate simply by the cleaning agent coming into contact with the dirt in step (1), it is necessary to apply physical force in step (2) to emulsify and disperse the dirt in the cleaning solution. This step (2) is known as the cleaning step, and the cleaning power is determined by how much dirt transfers to the cleaning solution.

The situation is the same for makeup removers that are washed off. In makeup removers (cleaning agents), the makeup (dirt) being removed is an artificially created, highly hydrophobic component (extremely low water solubility), so in most cases it cannot be removed with a composition consisting of surfactants and water, and an oil is used as the main base. Regardless of which agent is used to remove makeup, the cleaning step (2) also requires physical force.
In the present invention, by simply performing steps (1) and (3), makeup can be dispersed even from small recesses such as pores and can be thoroughly removed. This is not limited to cosmetics such as makeup, but is also applicable to other oily stains, and is particularly effective for long-lasting foundations, for example.
