[0007] Problems to be Solved by the Invention

[0008] If the coating type film forming agent described in Patent Document 1 is applied to the skin and crosslinked, a film is formed on the skin surface.

[0009] Conventional coating type film forming agents sometimes repel the skin, etc., and uneven application occurs. As a result, for example, as Figure 1 shown, there is a case where oiliness protrudes locally at a position where the oil phase component among the second agent components becomes excessive. Such uneven application and oiliness can induce an unnatural appearance, so it is desired to improve such adverse conditions.

[0010] Therefore, the subject of the present disclosure is to provide an oil-in-water type composition for the second agent of a coating type film forming agent that can reduce or prevent adverse conditions such as uneven application and oiliness of the film.

Detailed Description

[0067] Hereinafter, embodiments of the present disclosure will be described in detail. The present disclosure is not limited to the following embodiments, and various modifications can be made within the scope of the gist of the invention.

[0068] The oil-in-water type composition of the present disclosure includes: a dispersion medium containing water and microgel; oil droplets dispersed in the dispersion medium; and a silicone-based surface tension regulator having a surface tension of 30.0 mN / m or less at 25°C in an aqueous solution containing 1% by mass of the surface tension regulator. The oil-in-water type composition is used as the second agent of a coating film-forming agent including a first agent and a second agent. The first agent includes a crosslinking reactive component constituting the film, and the second agent includes a crosslinking component that crosslinks the crosslinking reactive component.

[0069] Although not limited by theory, the principle of action for reducing or preventing uneven coating and oiliness of the resulting film when using the oil-in-water type composition of the present disclosure as the second agent of a coating film-forming agent is as follows.

[0070] The coating film-forming agent of the present disclosure includes a first agent and a second agent. The first agent includes a crosslinking reactive component constituting the film, and the second agent includes a crosslinking component that crosslinks the crosslinking reactive component. Therefore, it is considered that if uneven coating occurs when preparing a film using such a first agent and a second agent, unevenness also occurs in the thickness and the like of the resulting film. As a result, it is considered that, as Figure 1 shown, reflection portions are generated in the resulting film, which causes poor conditions such as oiliness. Here, in Figure 1 , the second agent repels the first agent layer. As a result, it is considered that, for example, the oil phase component containing a catalyst among the second agent components is dispersed, and positions where the crosslinking reaction easily proceeds are locally formed. Therefore, the resulting film is uneven and reflection portions are formed.

[0071] Therefore, the present inventors first studied the effect of various thickeners on the viscoelasticity of the second agent in order to improve uneven coating. As a result, it was found that in the oil-in-water type composition used as the second agent of a coating film-forming agent, a thickener of a type that can exhibit thickening properties through a moderate packing effect (frictional action between microgel particles), such as microgel, is more effective than a general thickener that exhibits a thickening effect through a network structure formed by polymer chains. However, uneven coating cannot be sufficiently improved only by such a thickener.

[0072] Based on this, the present inventors further studied the influence of the surface tension of the second agent. As a result, it was found that when a specified silicone-based surface tension regulator among various surface tension regulators (such as surfactants, etc.) is mixed with a microgel and used in an oil-in-water type composition used as the second agent of a coating type film-forming agent, coating unevenness is improved. As a result, defective conditions such as oiliness of the film can be reduced or prevented. It is considered that this is a specific phenomenon that can be produced by the synergistic effect of the thickening action accompanied by the appropriate filling effect of the microgel and the use of a specific silicone-based surface tension regulator.

[0073] As described above, when the oil-in-water type composition of the present disclosure containing a microgel and a specific silicone-based surface tension regulator is used as the second agent of a coating type film-forming agent, coating unevenness and defective conditions such as oiliness of the film can be reduced or prevented. However, the present inventors further found that Figure 2 when it is desired to improve even slight oiliness as shown in the dashed box, it is effective to further mix non-porous particles into the second agent.

[0074] Generally, it is considered that since porous particles are likely to scatter light due to the multiple pores formed, the mixing of porous particles is effective for the oiliness of the film. However, in the oil-in-water type composition of the present disclosure, unexpectedly, when porous particles are mixed, coating unevenness is likely to occur. As a result, defective conditions such as oiliness of the film are likely to occur. It is considered that this is because if porous particles are mixed in the oil-in-water type composition of the present disclosure, at least one of the microgel and the specific silicone-based surface tension regulator mixed in the composition to improve coating unevenness is absorbed by the porous particles and cannot exhibit the desired function. Therefore, it is considered that it is effective to mix non-porous particles instead of porous particles in the oil-in-water type composition of the present disclosure.

[0075] The definitions of the terms in the present disclosure are as follows.

[0076] In the present disclosure, the so-called "body modifying film" refers to a film that, when formed on the skin of a subject, is intended to have the appearance of natural skin. Here, the so-called "appearance of natural skin" means that when applied to the skin, the body modifying film exhibits properties similar to or the same as at least one selected from the appearance, touch, and texture of actual skin. For example, the skin treated with the film can exhibit the physical properties (such as elasticity and hardness) of actual (e.g., current) skin.

[0077] As used herein, "body correction" refers to improving, visually and / or haptically, a defect of a subject's body or skin by covering, concealing, or masking the defect, but does not include methods of performing surgery, treatment, or diagnosis on a human. Herein, "defect of the body" may refer to, for example, a part of the subject's body that the subject perceives as a spot or a wound, or that a person skilled in the art, such as a dermatologist, cosmetologist, or plastic surgeon, would consider as a spot or a wound. The "defect of the body" includes defects of the skin and laxity of the soft tissues of the body (e.g., laxity or relaxation of the skin, breasts, buttocks, abdomen, palate, neck, etc.). In addition, the "defect of the skin" includes these items of the subject's skin that the subject perceives as a spot or a wound. Examples of defects of the skin include nevus flammeus or port-wine stain (e.g., simple hemangioma or median port-wine stain), chloasma, wrinkles, spots, acne, moles, scars, tattoos, nevi, skin deformations, nevus spilus, sunburn, aging, uneven skin color, lax skin, rough skin, hyperpigmentation, enlarged pores, telangiectasia, redness, shine, cellulite, stretch marks, or reduced skin elasticity.

[0078] As used herein, "oil-in-water type composition" refers to a composition in a state where oil droplets are dispersed in a dispersion medium containing water. As such a composition, for example, a composition obtained by oscillating a liquid separated into a water and an oil state to forcibly disperse the oil droplets in a dispersion medium containing water, and an emulsified composition in which oil droplets are dispersed in a dispersion medium containing water by blending an emulsifier can be included.

[0079] As used herein, "viscosity" refers to a measure of the resistance of a fluid that deforms by either shear stress or tensile stress. For example, the viscosities of the first agent and the second agent in a coating film-forming agent affect the thickness, ductility, and uniformity and / or consistency of the layer formed on a substrate. Viscosity can be reported as either dynamic viscosity (alias, absolute viscosity, representative units are Pa·s, poise, P, cP) or kinematic viscosity (representative units are cm 2 / s, stokes, St, cst). The kinematic viscosity is obtained by dividing the dynamic viscosity by the density of the fluid for which the measurement was made. The viscosity ranges of the components disclosed in this specification are generally provided by the suppliers of the respective components as units of kinematic viscosity (e.g., cst) measured using a rheometer or a Cannon-Fenske viscometer, but the viscosity of a fluid can also be measured using a rheometer (e.g., a linear shear rheometer or a dynamic shear rheometer) or a viscometer (also referred to as a viscosity measuring instrument, e.g., a capillary viscometer or a rotational viscometer).

[0080] In the present disclosure, the so-called "microgel" refers to a water-swellable three-dimensionally crosslinked microgel formed in an aqueous phase, and a thickener of a type thickened by the friction of the swollen microgel particles. The microgel can typically contain a solvent.

[0081] In the "crosslinking" in the present disclosure, the concept called "curing" is generally also included.

[0082] In the present disclosure, the so-called "body surface" refers to the skin surface of the body.

[0083] "Oil-in-water type composition"

[0084] The oil-in-water type composition of the present disclosure (sometimes simply referred to as "composition".) can be used as the second agent of a coating type film-forming agent containing a first agent and a second agent, and can reduce or prevent poor conditions such as oiliness of the obtained film. The first agent contains a crosslinking reactive component constituting the film, and the second agent contains a crosslinking component that crosslinks the crosslinking reactive component.

[0085] The effect of reducing the oiliness of the obtained film can be evaluated by the glossiness test in the examples described later. The film prepared using the oil-in-water type composition of the present disclosure can, for example, achieve a glossiness of 100 or less, 95 or less, 90 or less, 85 or less, 80 or less, 75 or less, or 70 or less at a reflection angle (sometimes also referred to as "light receiving angle".) of 45° or 50°. There is no particular limitation on the lower limit value of such glossiness. For example, it can be 30 or more, 35 or more, 40 or more, 45 or more, or 50 or more.

Here, the projected area equivalent diameter can be, for example, the particle diameter in the case of converting to a circular particle having the same area as the projected area of the microgel particles observed by a transmission electron microscope. Such a projected area equivalent diameter can be defined as the average value of 10 or more particles.

[0148] (Emulsifier)

[0149] In some embodiments, the oil-in-water type composition of the present disclosure may contain an emulsifier. The so-called emulsifier in the present disclosure refers to an agent having an emulsifying function (surface activity), and may also include an agent generally referred to as a surfactant. In addition, the oil-in-water type composition containing an emulsifier may be referred to as an oil-in-water type emulsified composition.

[0150] Regarding the blending amount of the emulsifier, there is no particular limitation. For example, from the viewpoint of emulsion stability and the like, based on the total amount of the composition, it may be 0.01% by mass or more, 0.05% by mass or more, 0.1% by mass or more, or 0.2% by mass or more.

It should be noted that when the surface tension of the silicone-based surfactant in an aqueous solution containing 1% by mass of the surfactant is 30.0 mN / m or less at 25 °C, the silicone-based surfactant can be regarded as the silicone-based surface tension regulator described later.

[0155] Among the emulsifiers, from the viewpoints of the uniform dispersion (emulsifying property) of the catalyst in the composition and the storage stability of the catalyst, etc., a polymer emulsifier is preferred. A polymer emulsifier can refer to an emulsifier (surfactant) that typically has a large molecular weight and low emulsifying ability compared to general emulsifiers (surfactants). The polymer emulsifier can also be used in combination with the above-mentioned emulsifiers.

[0156] From the viewpoints of emulsifying property, etc., the weight-average molecular weight of the polymer emulsifier can be 500 or more, 700 or more, 1,000 or more, 1,500 or more, or 2,000 or more.

Among them, from the viewpoints of emulsion stability, etc., an acrylic acid (ester) / C10-30 alkanol acrylate crosslinked polymer is preferred.

[0164] From the viewpoints such as the uniform dispersion (emulsification) of the catalyst in the composition, the blending amount of the polymer emulsifier relative to the total amount of the composition may be 0.01% by mass or more, 0.05% by mass or more, 0.1% by mass or more, or 0.2% by mass or more.

[0166] The HLB of a general emulsifier (surfactant) other than the polymer emulsifier may be 2.0 or more, 3.0 or more, or 4.0 or more. In addition, it may be 10.0 or less, 9.0 or less, or 8.0 or less.

[0167] 〈Silicone-based surface tension regulator〉

[0168] The oil-in-water composition of the present disclosure contains a silicone-based surface tension regulator (sometimes simply referred to as "surface tension regulator"). Furthermore, the surface tension of such a surface tension regulator in an aqueous solution containing 1% by mass of the surface tension regulator at 25°C is 30.0 mN / m or less. The surface tension regulator can be used alone or in combination of two or more. It should be noted that the surface tension is the average value of the values obtained by measuring 3 times at 25°C using a Wilhelmy plate.

[0169] From the viewpoints such as the improvement effect of uneven application, the surface tension of the surface tension regulator is preferably 29.0 mN / m or less, 28.5 mN / m or less, 28.0 mN / m or less, 27.5 mN / m or less, or 27.0 mN / m or less. As the lower limit value of such a surface tension, for example, it may be 20.0 mN / m or more, 21.0 mN / m or more, 22.0 mN / m or more, 23.0 mN / m or more, 24.0 mN / m or more, or 25.0 mN / m or more.

[0170] From the viewpoints such as the improvement effect of uneven application, the blending amount of the surface tension regulator relative to the total amount of the composition is preferably 0.01% by mass or more, 0.03% by mass or more, 0.05% by mass or more, 0.07% by mass or more, or 0.1% by mass or more. As the upper limit value of such a blending amount, for example, it may be 10% by mass or less, 7.0% by mass or less, 5.0% by mass or less, 3.0% by mass or less, or 1.0% by mass or less.

[0171] As the surface tension regulator, as long as it is a silicone-based agent having a specified surface tension (an agent containing silicone components such as silicone chains), there is no particular limitation. For example, it may also be a silicone-based surfactant having the above-described emulsifying ability (surface activity), or it may also be an agent without emulsifying ability. When the surface tension regulator is a silicone-based surfactant having emulsifying ability, the surface tension regulator can be included at the interface between the oil droplets and the dispersion medium, etc. When it is an agent without emulsifying ability, the surface tension regulator can be included in the dispersion medium. Thus, the surface tension regulator can be included in the above-described dispersion medium and / or oil droplets.

[0172] As a specific example of the surface tension regulator, from the viewpoint of the effect of improving coating unevenness, it is preferably at least one selected from polyoxyethylene / methylpolysiloxane copolymer, dimethylpolysiloxane / methyl(polyoxyethylene)siloxane copolymer, and bis-PEG-18 methyl ether dimethylsilane. Among them, more preferably, they are polyoxyethylene / methylpolysiloxane copolymer and dimethylpolysiloxane / methyl(polyoxyethylene)siloxane copolymer as silicone-based surfactants, and further preferably polyoxyethylene / methylpolysiloxane copolymer, and particularly preferably PEG-10 methyl ether polydimethylsiloxane and PEG-11 methyl ether polydimethylsiloxane.

[0173] 〈Non-porous particles〉

[0174] In some embodiments, the oil-in-water type composition of the present disclosure contains non-porous particles. If a composition containing non-porous particles is used as the second agent, the oiliness of the resulting film can be further reduced or prevented. In particular, after applying the first agent of the coating film-forming agent to the body surface to form the first agent layer and then applying the second agent, it is preferable to use an oil-in-water type composition containing non-porous particles as the second agent. In this case, since the non-porous particles contained in the second agent are easily arranged near the surface of the film, the oiliness of the film can be further reduced or prevented. The non-porous particles can be used alone or in combination of two or more. Here, the so-called "non-porous" means substantially non-porous, and is not limited to the case where there are completely no pores. The so-called non-porous particles of the present disclosure may refer to, for example, particles having a BET specific surface area of 100 m 2 / g or less, 80 m 2 / g or less, 50 m 2 / g or less, 30 m 2 / g or less, or 25 m 2 / g or less as measured by the BET method (gas adsorption method). As the lower limit value of such a BET specific surface area, there is no particular limitation. For example, it may be 0 m 2 / g or more, more than 0 m 2 / g, 1 m 22 m or more per g 2 per g or more.

[0175] From the viewpoint of suppressing oiliness, the blending amount of the non-porous particles is preferably 1.0% by mass or more, 2.0% by mass or more, 3.0% by mass or more, 4.0% by mass or more, 5.0% by mass or more, 6.0% by mass or more, 7.0% by mass or more, 8.0% by mass or more, or 9.0% by mass or more, relative to the total amount of the composition. As the upper limit value of such a blending amount, for example, from the viewpoint of preventing poor conditions such as uneven application, it is preferably 20% by mass or less, 15% by mass or less, 13% by mass or less, 12% by mass or less, 11% by mass or less, or 10% by mass or less.

[0176] The size of the non-porous particles is not particularly limited. For example, from the viewpoint of suppressing oiliness, it preferably exhibits a circle equivalent diameter in terms of area of 1.0 μm or more, 1.5 μm or more, 2.0 μm or more, 2.5 μm or more, 3.0 μm or more, or 3.5 μm or more, and 10 μm or less, 9.0 μm or less, 8.0 μm or less, 7.0 μm or less, 6.0 μm or less, or 5.0 μm or less. Here, the so-called circle equivalent diameter in terms of area can be, for example, the particle diameter in the case of converting to a circular shape having the same area as the projected area of the non-porous particles observed with a transmission electron microscope. Such a circle equivalent diameter in terms of area can be defined as the average value of 10 or more particles.

[0177] As the non-porous particles, for example, they can be solid non-porous particles or can be hollow non-porous particles. From the viewpoint of suppressing oiliness, solid non-porous particles are preferred. From the viewpoint of suppressing oiliness, the non-porous particles are preferably spherical particles, and preferably particles having a refractive index of 1.4 to 1.6. Here, the so-called "spherical" in the non-porous particles includes a sphere, a substantially spherical shape, and a rotational ellipsoid. Even if there are irregularities on the surface, as long as the overall shape of the particle can be judged as spherical, it corresponds to the so-called "spherical" in the present disclosure. Specifically, the so-called "spherical particles" in the non-porous particles are not limited to spheres, and can include particles having a minor axis / major axis ratio (ellipticity) of 1.5 or less, 1.2 or less, or 1.1 or less. As the lower limit value of such a ratio, for example, it can be 1.0 or more, more than 1.0, or 1.2 or more.

[0178] As the material of the non-porous particles, there is no particular limitation, and it may be an inorganic material or a resin material. Specific examples of such materials include inorganic oxides (e.g., zinc oxide, titanium dioxide, alumina, and silica), boron nitride, magnesium carbonate, magnesium hydroxide, barium sulfate, kaolin, perlite, talc, mica, silicone resin, polyamide resin, and (meth)acrylic resin, etc. Among them, from the viewpoint of suppressing oiliness, an inorganic material is preferred, an inorganic oxide is more preferred, and silica (silicon dioxide) is particularly preferred.

[0179] The non-porous particles may be particles hydrophobically treated with a surface treatment agent or particles not hydrophobically treated. In the case of hydrophobically treating, there is no particular limitation on such treatment, and examples thereof include dimethylsilylation treatment and trimethylsilylation treatment, etc.

[0180] If porous particles are mixed in the oil-in-water type composition of the present disclosure, it is easy to cause uneven spreading, and as a result, poor conditions such as oiliness of the film may sometimes occur. Therefore, when porous particles are mixed in the oil-in-water type composition, from the viewpoint of suppressing uneven spreading and poor conditions such as oiliness, the porous particles are preferably mixed in a proportion of 10% by mass or less, 8.0% by mass or less, 5.0% by mass or less, 3.0% by mass or less, 1.0% by mass or less, 0.5% by mass or less, or 0.1% by mass or less with respect to the total amount of the composition. More preferably, the porous particles are not mixed in the oil-in-water type composition. It should be noted that the so-called porous particles refer to particles having a large number of pores on the surface compared with the non-porous particles of the present disclosure, and may refer to, for example, particles having a BET specific surface area of 300 m 2 / g or more, 500 m 2 / g or more, or 700 m 2 / g or more as measured by the BET method (gas adsorption method).

[0181] Smearing-type film-forming agent

[0182] The above-mentioned oil-in-water type composition of the present disclosure can be suitably used as the second agent of a smearing-type film-forming agent (sometimes simply referred to as "forming agent") containing a first agent and a second agent. Such a forming agent can form a film, for example, by applying the second agent to the first agent layer after applying the first agent to the body surface to form the first agent layer, thereby crosslinking the first agent layer. The film obtained by the smearing-type film-forming agent of the present disclosure can be a body-modifying film having a body-modifying function or a film not having a body-modifying function.

[0183] In several embodiments, the spreading property of the first agent of the spreadable film-forming agent can be evaluated by the viscosity measured using a B-type viscometer (manufactured by Shibaura Systems Co., Ltd., Visometron (trademark)). The viscosity of the first agent in the spreadable film-forming agent of the present disclosure measured under the conditions of 25°C and 60 revolutions per minute (rotor No. 3 or No. 4) (for example, the viscosity immediately after production) can be, for example, 100 mPa·s or more, 500 mPa·s or more, 1,000 mPa·s or more, 2,000 mPa·s or more, 5,000 mPa·s or more, 7,500 mPa·s or more, 10,000 mPa·s or more, or 15,000 mPa·s or more, and can be 1,000,000 mPa·s or less, 750,000 mPa·s or less, 500,000 mPa·s or less, 250,000 mPa·s or less, 200,000 mPa·s or less, 175,000 mPa·s or less, 150,000 mPa·s or less, 125,000 mPa·s or less, 100,000 mPa·s or less, or 80,000 mPa·s or less. Among them, from the viewpoints of smooth spreading property and suppression of liquid dripping from the skin, etc., the first agent of the spreadable film-forming agent preferably has a viscosity of 20,000 mPa·s or less, 15,000 mPa·s or less, or 10,000 mPa·s or less immediately after production, and preferably has a viscosity of 3,000 mPa·s or more, 5,000 mPa·s or more, or 7,000 mPa·s or more.

[0184] In some embodiments, the spreading performance of the second agent of the spreadable film-forming agent can be evaluated by the viscosity measured using a B-type viscometer (manufactured by Shibaura Systems Co., Ltd., Visometron (trademark)). The viscosity of the second agent in the spreadable film-forming agent of the present disclosure measured under the conditions of 25°C and 10 revolutions per minute (rotor No. 7) (for example, the viscosity immediately after production) can be, for example, 10,000 mPa·s or more, 20,000 mPa·s or more, 30,000 mPa·s or more, 40,000 mPa·s or more, or 50,000 mPa·s or more, and can be 1,000,000 mPa·s or less, 750,000 mPa·s or less, 500,000 mPa·s or less, 250,000 mPa·s or less, 200,000 mPa·s or less, 175,000 mPa·s or less, 150,000 mPa·s or less, 125,000 mPa·s or less, 120,000 mPa·s or less, 115,000 mPa·s or less, or 110,000 mPa·s or less. Among them, from the viewpoints of improving uneven spreading and suppressing oiliness, the second agent of the spreadable film-forming agent preferably has a viscosity of 20,000 mPa·s or more, 30,000 mPa·s or more, 40,000 mPa·s or more, or 50,000 mPa·s or more immediately after production, and preferably has a viscosity of 200,000 mPa·s or less, 175,000 mPa·s or less, 150,000 mPa·s or less, 125,000 mPa·s or less, 120,000 mPa·s or less, 115,000 mPa·s or less, or 110,000 mPa·s or less.

[0185] 〈First agent〉

[0186] The first agent constituting the spreadable film-forming agent of the present disclosure contains at least one selected from a second unsaturated organopolysiloxane and a second hydrogenated functionalized polysiloxane. Among them, in the case where the first agent contains only the second unsaturated organopolysiloxane among the second unsaturated organopolysiloxane and the second hydrogenated functionalized polysiloxane, the second agent composed of the above oil-in-water type composition contains the above first hydrogenated functionalized polysiloxane. In addition, in the case where the first agent contains only the second hydrogenated functionalized polysiloxane among the second unsaturated organopolysiloxane and the second hydrogenated functionalized polysiloxane, the second agent contains the first unsaturated organopolysiloxane.

[0187] There is no particular limitation on the dosage form of the first agent. For example, it can be in the form of a single-phase system composed of an oil phase, a non-emulsified water-in-oil or oil-in-water two-phase system, or a two-phase system composed of a water-in-oil emulsion composition or an oil-in-water emulsion composition. Here, the so-called single-phase system composed of an oil phase is typically in an anhydrous form. In the present disclosure, the so-called "anhydrous" not only means that water is not contained in the composition, but also means that the water content is low, that is, 10% by mass or less, 5% by mass or less, 2% by mass or less, 1% by mass or less, or 0.1% by mass or less. In addition, the so-called non-emulsified two-phase system can include an oil-in-water composition in which droplets of water are forcibly dispersed in a dispersion medium containing oil by shaking a liquid separated into a water and oil state, or a water-in-oil composition in which droplets of oil are forcibly dispersed in a dispersion medium containing water.

[0188] These dosage forms can be appropriately prepared by conventional methods using crosslinking-reactive components and known materials such as oil components, emulsifiers, and water as described later, if necessary.

[0189] Since the first agent can be applied by being applied to the body surface or the like, from the viewpoint of application performance, it preferably has a glass transition temperature below body temperature. For example, the glass transition temperature can be 37°C or below, 25°C or below, 10°C or below, or 0°C or below. There is no particular limitation on the lower limit value of the glass transition temperature. For example, it can be -30°C or above, -20°C or above, or -10°C or above. Here, the so-called "glass transition temperature" refers to the temperature at which a transition from a solid state to a liquid state occurs. For example, it can be measured using a differential scanning calorimeter (DSC) based on ASTM D3418-03.

[0192] Regarding the mixing amount of the second unsaturated organopolysiloxane in the first agent, it can be appropriately adjusted according to the required film properties and the like, and there is no particular limitation. For example, as the mixing amount of the second unsaturated organopolysiloxane, relative to the whole of the first agent, it can be 5% by mass or more, 10% by mass or more, 20% by mass or more, 30% by mass or more, 35% by mass or more, or 40% by mass or more, and can be 90% by mass or less, 80% by mass or less, 70% by mass or less, 60% by mass or less, 50% by mass or less, or 45% by mass or less.

Among them, vinyl-terminated polydimethylsiloxane is preferred, and divinyl polydimethylsiloxane and 1,3-divinyltetramethyldisiloxane are more preferred.

[0202] Regarding the blending amount of other polymers in the first agent, it may be appropriately adjusted according to the required film properties, etc., and there is no particular limitation. For example, as the blending amount of other polymers, it may be 0.01% by mass or more, 0.1% by mass or more, 0.3% by mass or more, or 0.5% by mass or more with respect to the whole first agent, and may be 20% by mass or less, 15% by mass or less, or 10% by mass or less.

[0203] 〈Functional group ratios in the second unsaturated organopolysiloxane, the second hydrogenated functionalized polysiloxane, and other polymers〉

[0207] 〈Second agent〉

[0209] In addition, the second agent may similarly blend the above-described other polymers that can be blended in the first agent.

[0210] In the second agent, when using the first unsaturated organopolysiloxane and other polymers, these functional group ratios may adopt the same ratios as the functional group ratios in the second unsaturated organopolysiloxane and other polymers described above.

[0211] 〈Optional components〉

[0212] The coating film-forming agent of the present disclosure may appropriately blend various components in the first agent and / or the second agent within a range that does not adversely affect the effects of the present disclosure.

[0218] "Method of Using a Coating-Type Film-Forming Agent"

[0219] The coating film-forming agent of the present disclosure can be used, for example, for cosmetic or medical purposes. Here, the method of using the coating film-forming agent of the present disclosure does not include methods of performing surgery, treatment, or diagnosis on humans.

[0220] As the method of using the coating film-forming agent of the present disclosure, there is no particular limitation, and examples thereof include a method in which, after applying the first agent to the body surface to form a first agent layer, applying the second agent on the first agent layer to cause crosslinking to form a film; a method in which, after applying the second agent to the body surface to form a second agent layer, applying the first agent on the second agent layer to cause crosslinking to form a film; or a method in which, after mixing the first agent and the second agent to prepare a mixture, applying the mixture to the body surface to cause crosslinking to form a film. From the viewpoint of obtaining a uniform film with few unevennesses, as such a method of use, a method in which, after applying the first agent to the body surface to form a first agent layer, applying the second agent on the first agent layer to cause crosslinking to form a film is preferred. Here, for the first agent and the second agent, the above-mentioned materials and the like can be used in the same manner.

[0221] This method can be completed in one step, or such a method can also be performed multiple times (for example, 2 times or more or 3 times or more) on the formed film. In the case of performing multiple times, this method can include, for example, any of the following operations:

[0222] After applying the first agent to the formed film to form a first agent layer, applying the second agent on the first agent layer to further form a film, or

[0223] After applying the second agent to the formed film to form a second agent layer, applying the first agent on the second agent layer to further form a film, or

[0224] After mixing the first agent and the second agent to prepare a mixture, applying the mixture to the formed film to further form a film.

[0225] In some embodiments, a cosmetic can be applied to the body surface before applying the first agent, the second agent, or a mixture containing the first agent and the second agent to the body surface; a cosmetic can be applied to the body surface after applying the first agent to the body surface to form a first agent layer and then applying the cosmetic on the first agent layer, and then the second agent is applied in a manner covering the cosmetic; a cosmetic can be applied to the body surface after applying the second agent to the body surface to form a second agent layer and then applying the cosmetic on the second agent layer, and then the first agent is applied in a manner covering the cosmetic; or a cosmetic can be applied to the formed film after the film is formed.

[0226] As a cosmetic, there is no particular limitation, and for example, skincare cosmetics such as beauty essences, lotions, and milky lotions, sunscreen cosmetics (sun protection cosmetics), base cosmetics, or color cosmetics such as foundations, lip glosses, lipsticks, eyeshadows, and nail polishes, or cosmetics that combine two or more functions of these cosmetics can be used.

[0227] In addition, in some embodiments, the method of using the coating-type film-forming agent of the present disclosure can also be utilized as a beauty method. For example, the skin exposed to dryness sometimes unconsciously has its moisture taken away, resulting in a state where the moisture content of the stratum corneum on the skin surface is not maintained. If the skin lacks moisture, the moisturizing components (natural moisturizing factor: Natural Moisturizing Factor (NMF)) produced by the skin itself cannot be produced smoothly. As a result, it is considered that the barrier function and moisturizing function on the skin surface are reduced, the skin is easily damaged, and thus it loses moisture and causes skin roughness and the like.

[0228] On the other hand, if a film formed by the coating-type film-forming agent of the present disclosure is applied to the skin, the skin can be well moisturized by the occlusion effect (the effect of preventing moisture from escaping from the skin) brought by the film. As a result, for example, since the production function of the moisturizing components produced by the skin itself is improved, and the smoothness of the renewal in the stratum corneum is also improved, problems such as skin roughness are less likely to occur, and the beauty effect can be enhanced. It should be noted that the so-called "beauty method" refers to a method of applying the coating-type film-forming agent of the present disclosure to the skin to form a film and adjusting the state of the skin to be beautiful or making the state of the skin beautiful, which is different from the methods of performing surgery, treatment, or diagnosis on humans.

[0229] As a method of applying the first agent or the second agent to the skin, the cosmetic application layer, or the first agent layer or the second agent layer, there is no particular limitation, and for example, means such as spreading with fingers, spray application, and transfer can be adopted.

[0230] In addition, for example, when the first agent and / or the second agent are separated into water and oil, from the viewpoint of improving uneven application, it is preferable to shake these agents to forcibly form a two-phase system (water-in-oil type or oil-in-water type).

[0231] 〈Application Site〉

[0232] The coating-type film-forming agent of the present disclosure can be applied to any position as long as it is on the surface of the skin in all parts of the body, that is, on the body surface. For example, it can be appropriately applied to the skin surfaces of the head, face (lips, eyes, nose, cheeks, forehead, etc.), neck, ears, hands, arms, legs, feet, chest, abdomen, back, buttocks, etc. Here, the skin also includes nails and the like that have hardened due to keratinization of the epidermis of the skin.

[0233] "Kit with a Smear-Type Film-Forming Agent"

[0234] The smear-type film-forming agent of the present disclosure can be provided in the form of a kit having a first agent and a second agent that constitute such a film-forming agent. In addition to the first agent and the second agent, the kit may have, for example, members for facilitating the application of the first agent or the like to the body surface, optional members such as the above various cosmetics, or may be used in combination with these members.

[0235] As such optional members, for example, an instruction manual, a spatula-shaped applicator, a brush, a cotton swab, a cutter, scissors, the above various cosmetics, a cleaning solution for removing the film from the body surface, a mirror, etc. can be cited. Here, the so-called "instruction manual" may include, in addition to the general instruction manual attached in the form of a document in the kit, for example, a substance in a state where the instruction manual is printed on the packaging container for housing the kit or a packaging container such as a tube for injecting the first agent or the like.

[0236] In a certain embodiment, in order to prevent the contact of the first agent and the second agent, for example, these agents can be enclosed in separate containers, or can be separately enclosed in each region of a container having two or more regions. In addition, these enclosed agents can be configured to be used one at a time, or can also be configured to be mixed together before or during use.

[0237] "Film"

[0238] 〈Thickness〉

[0239] The thickness of the film prepared using the above smear-type film-forming agent of the present disclosure is not particularly limited. For example, it can be appropriately adjusted in consideration of air permeability, invisibility, compressibility, occlusivity to the skin, etc. As the thickness of the film, for example, it can be 0.5 μm or more, 1 μm or more, 10 μm or more, 30 μm or more, 40 μm or more, 50 μm or more, 70 μm or more, or 100 μm or more. There is no particular limitation on the upper limit value of the thickness. For example, it can be 1 mm or less, 800 μm or less, 500 μm or less, 300 μm or less, 150 μm or less, 100 μm or less, 90 μm or less, 80 μm or less, 70 μm or less, 60 μm or less, or 50 μm or less. Here, the thickness can be defined as the average value calculated by measuring the thickness of any part of the film 5 times using a high-precision digital micrometer (MDH-25MB, manufactured by Mitutoyo Corporation). In addition, the thickness of the film refers to the thickness after the film prepared using the smear-type film-forming agent is sufficiently dried (for example, after being dried for 6 hours or more in a room temperature atmosphere).

[0240] Examples

[0241] Examples are given below to further illustrate the present invention in detail, but the present invention is not limited to these. It should be noted that hereinafter, unless otherwise specified, the blending amount is expressed in mass%. In addition, the evaluation methods described in the examples are not limited to the oil-in-water type compositions or forming agents described in the examples, and the above oil-in-water type compositions or forming agents can also be implemented in the same manner.

[0242] "Evaluation Test"

[0243] The following tests were performed using each test sample obtained by the following manufacturing method, and the results are summarized in Tables 1 to 5 and Figures 3 - 4 in.

[0244] 〈Surface Tension〉

[0245] A test sample for evaluating surface tension was prepared by adding a test material as a surface tension regulator to ion-exchanged water at a mixing ratio of 1% by mass. At 25°C in an atmosphere, using a dynamic contact angle measuring device (DCAT21, manufactured by Data physics), the surface tension of such a test sample was measured 3 times by the Wilhelmy method using a Wilhelmy plate. The surface tension values recorded in the table are the average values obtained from the 3 measurements.

[0246] 〈Viscosity〉

[0247] The viscosity of the test sample was measured at 25°C, rotor No. 7, and 10 rpm using a B-type viscometer (Visometron (trademark), manufactured by Shibaura Semtec Co., Ltd.). The viscosity values recorded in the table are the average values obtained from the 3 measurements.

[0248] 〈Smearing Unevenness Evaluation Test: Repellency Resistance〉

[0249] After forming a first agent layer by applying the first agent of the smear-type film-forming agent to the back of the hands of 20 professional reviewers, each test sample was applied to the first agent layer, and the smearing unevenness at this time was evaluated according to the following criteria:

[0264] 〈Glossiness〉 [[ID=3l]]

[0265] After forming the first-agent layer by applying the first agent of the coating-type film-forming agent to black artificial leather (Supplerレ (trademark), manufactured by Idemitsu Fine Techno Co., Ltd.), the test sample as the second agent was applied to the first-agent layer, and a film with a film thickness of about 100 μm after drying at room temperature for 6 hours was formed to prepare a test sample for glossiness evaluation. The obtained test sample was placed on a goniophotometer (Gonio SPECTROPHOTOMETER GSP-1B, manufactured by Murakami Color Technology Research Institute), and the glossiness in the range of reflection angles from -25° to 75° was measured.

[0266] 《Test Example 1: Influence of Surface Tension Regulator》

[0267] In Test Example 1, the influence of uneven application caused by different surface tension regulators in the second agent mixed in the first-agent layer of the coating-type film-forming agent was studied. The results are shown in Table 1. It should be noted that the test samples of Reference Examples 1 to 8 are described as reference examples because they contain only the surface tension regulator and water and do not contain components such as catalysts.

[0268] <First Agent: Single-Phase System Composed of Oil Phase>

[0269] 30 parts by mass of divinyl polydimethylsiloxane with a viscosity of 165,000 cst as the second unsaturated organic polysiloxane, 7 parts by mass of hydrogenated polydimethylsiloxane with a viscosity of 45 cst as the second hydrogenated functionalized polysiloxane, 6 parts by mass of silylated silica as a filler, and 57 parts by mass of a mixture of polydimethylsiloxane and trisiloxane as an oil component are uniformly mixed to prepare the first agent.

[0270] <Second Agent>

[0271] Using the formulation shown in Table 1, the second agent such as an oil-in-water type composition is manufactured by the following method. Here, the numbers shown below are the same as the numbers of the components on the left side of the formulation showing Table 1.

[0272] (Comparative Example 1)

[0273] After uniformly mixing the materials of No.1 to No.4 and No.9 to No.11 to prepare the aqueous phase portion, the materials of No.5 to No.8 are added to the aqueous phase portion and uniformly mixed to prepare the second agent of the oil-in-water type composition of Comparative Example 1.

[0274] (Reference Examples 1 to 8)

[0275] Test samples of Reference Examples 1 to 8 are prepared by mixing each surface tension regulator in water.

[0276] [Table 1]

[0277]

[0278] <Results>

[0279] It was confirmed from the results in Table 1 that the second agent of Comparative Example 1 without a surface tension regulator was prone to repel the first agent layer. On the other hand, it was found that when comparing Reference Examples 1 to 8, if a silicone-based surface tension regulator with a surface tension of 30.0 mN / m or less was used, the repulsion was improved.

[0280] <<Test Example 2: Influence of Thickener>>

[0281] In Test Example 2, the influence of uneven application caused by different thickeners in the second agent mixed in the coating-type film-forming agent was studied. The results are shown in Table 2. It should be noted that the composition in the formulation shown in Table 2 does not contain a surface tension regulator.

[0282] <First Agent>

[0283] The first agent of Test Example 1 was used in the same manner.

[0284] <Second dose>

[0285] (Comparative Examples 2 - 10)

[0286] Changed to the formulation in Table 2. Otherwise, the operation was the same as in Comparative Example 1 to prepare the second water - in - oil type compositions of Comparative Examples 2 - 10. It should be noted that the thickener was mixed during the preparation of the aqueous phase part.

[0287] [Table 2]

[0288]

[0289] <Results>

[0290] From the results of Comparative Examples 4 and 6 in Table 2, it can be seen that if a microgel - type thickener is used, there is a tendency to improve the repellency.

[0291] <<Test Example 3: Combined Effect of Specific Surface Tension Regulator and Thickener>>

[0292] In Test Example 3, the effect of the combination of a silicone - based surface tension regulator with a specified surface tension and a microgel - type thickener in the second dose of the coating - type film - forming agent on coating unevenness was studied. The results are shown in Tables 3 and 4.

[0293] <First dose>

[0294] The first dose of Test Example 1 was used in the same way.

[0295] <Second dose>

[0296] (Examples 1 - 9 and Comparative Examples 11 - 13)

[0297] Changed to the formulations in Tables 3 and 4. Otherwise, the operation was the same as in Comparative Example 1 to prepare the second water - in - oil type compositions of Examples 1 - 9 and Comparative Examples 11 - 13. It should be noted that the surface tension regulator and the thickener were mixed during the preparation of the aqueous phase part.

[0298] [Table 3]

[0299]

[0300] [Table 4]

[0301] Table 4

[0302]

[0303] <Results>

[0304] It was clearly confirmed from the results of Table 3 and Table 4 that if a silicone-based surface tension regulator with a surface tension of 30.0 mN / m or less is used in combination with a microgel-type thickener, the stain resistance is significantly improved.

[0305] <<Test Example 4: Combined Effects of Specific Surface Tension Regulators, Thickeners, and Particles>>

[0306] In Test Example 4, the effects of the combination of a silicone-based surface tension regulator having a specified surface tension, a microgel-type thickener, and particles in the second agent of the coating-type film-forming agent on coating unevenness and oiliness were studied. The results are shown in Tables 5 and 6. Note that the so-called reference comparative examples in Table 5 could have been examples in the first place because their compositions also contain specific surface tension regulators and thickeners. However, since they were used to compare the composition containing porous particles with the composition containing non-porous particles, they are referred to as reference comparative examples.

[0307] 〈First Agent〉

[0308] The first agent of Test Example 1 was used in the same manner.

[0309] 〈Second Agent〉

[0310] (Examples 10 to 21 and Reference Comparative Examples 1 to 4)

[0311] The formulations in Tables 5 and 6 were changed, and otherwise, the operation was the same as in Comparative Example 1 to prepare the second oil-in-water type compositions of Examples 10 to 21 and Reference Comparative Examples 1 to 4. Note that the surface tension regulator, thickener, and particles were mixed during the preparation of the aqueous phase portion.

[0312] [Table 5]

[0313]

[0314] [Table 6]

[0315]

[0316] 〈Results〉

[0317] It was clearly confirmed from the results of Tables 5 and 6 that if an oil-in-water type emulsion composition used as the second agent of the coating-type film-forming agent is further mixed with non-porous particles in addition to a silicone-based surface tension regulator with a surface tension of 30.0 mN / m or less and a microgel-type thickener, the oiliness resistance is further improved.

[0318] In addition, from the results of Reference Comparative Examples 1 to 4 in Table 5, it can be seen that if porous particles are mixed into the oil-in-water type emulsion composition, the stain resistance deteriorates.

[0319] In addition, from the results of Examples 17 and 20, it can also be seen that the oil light resistance is further improved when the dispersants are mixed.

[0320] 《Test Example 5: Glossiness of Film》

[0321] In Test Example 5, as the first agent of the coating film forming agent, the first agent of Test Example 1 was used in the same manner. As the second agent of the coating film forming agent, the oil-in-water type compositions of Comparative Example 1 and Example 20 were used, and the above glossiness evaluation was carried out. The results are shown in Figure 3 and Figure 4 .

[0322] 〈Results〉

[0323] From Figure 3 and Figure 4 , it was clearly confirmed that, compared with Comparative Example 1, when the oil-in-water type composition of Example 20 was used as the second agent, the glossiness, that is, the oiliness, decreased. From Figure 3 , it can be seen that Example 20 containing non-porous particles can reduce the glossiness by about 30% compared with Comparative Example 1. It should be noted that the glossiness of Comparative Example 1 and Example 20 at a reflection angle of 45° was 111.6 and 79.5 respectively, and the glossiness of Comparative Example 1 and Example 20 at a reflection angle of 50° was 109.3 and 82.1 respectively.
