Description

Application-type film-forming agent, kit containing said agent, and method of using said agent

[0001] The present disclosure relates to a spreadable film-forming agent, a kit including the agent, and a method of using the agent.

[0002] Known examples of applied film-forming agents include those that can be applied to the body surface to form a film that can correct wrinkles, scars, etc., and cosmetics that make pores less noticeable.

[0003] Patent Document 1 discloses a composition for in situ formation of a layer on the skin surface of a subject, the composition comprising one or more crosslinkable polymers, and an artificial skin comprising a layer formed from the composition.

[0004] Patent Document 2 discloses a cosmetic for correcting pores, which contains, in a gel structure formed from 1) crosslinked dimethicone and cyclomethicone, 2) 1 to 10 mass% of water, 3) 15 to 40 mass% of silica, 4) 1 to 10 mass% of titanium dioxide-coated spherical powder, and 5) 0.5 to 5 mass% of sericite, the surface of which may be coated with another metal oxide.

[0005] Patent Documents 3, 4, and 5 disclose a film-forming agent comprising a first agent containing a cross-linking reactive component and water, and a second agent containing a cross-linking component for cross-linking the cross-linking reactive component. These documents also disclose that the film-forming agent may contain various powders.

[0006] Patent Publication No. 2019-503396 Patent Publication No. 2009-155211 International Publication No. 2022 / 215531 International Publication No. 2022 / 215533 International Publication No. 2022 / 124079

[0007] When the topical film-forming agent described in Patent Document 1 is applied to the skin and crosslinked, a film is formed on the skin surface in a concave shape. Therefore, such a film-forming agent typically stretches and reduces wrinkles and other depressions in the skin, thereby making the wrinkles and other defects less noticeable. However, this stretching action alone has sometimes been insufficient to make the depression defects less noticeable.

[0008] Conventional cosmetics for correcting pores, such as those described in Patent Document 2, sometimes have insufficient effects or produce unnatural finishes.

[0009] Therefore, there has been a demand for the development of a paint-on film-forming agent that has an excellent effect of correcting recess defects such as pores and that also provides a natural finish.

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present disclosure is not limited to the following embodiments, and various modifications can be made within the scope of the present invention.

[0016] A paint-type film-forming agent according to one embodiment of the present disclosure comprises a first agent containing a crosslinkable component that constitutes a film, and a second agent containing a catalyst that crosslinks the crosslinkable component, wherein the first agent and / or the second agent contains 0.01% by weight or more and less than 1.5% by weight of pigment-grade particles having a refractive index of 2.0 or more.

[0017] Although not limited by the principle, the principle of action by which the paint-on film-forming agent of the present disclosure has an excellent effect of correcting recess defects such as pores and is capable of forming a film that provides a natural finish is believed to be as follows.

[0018] As shown in Figure 1(a), in a depression defect such as a pore, light incident thereon (indicated by the arrow in the figure) strikes the wall of the depression and shifts direction, creating a shadow, which is thought to make the defect more noticeable.

[0019] For example, conventional cosmetics with pore-correcting properties contain a large amount of pigment, which conceals pores when applied. Therefore, while pores can be made less noticeable, an unnatural finish may result. Furthermore, for example, cosmetics with a low pigment content may have a relatively low viscosity. In such cases, as shown in FIG. 1( b), it is difficult to apply the cosmetic thickly, and as a result, the depressions cannot be filled sufficiently, resulting in shadows similar to those in FIG. 1( a), making the defects more noticeable. Furthermore, even if the viscosity of a cosmetic with a low pigment content is increased using a thickener or the like, conventional cosmetics may cause the makeup to break down after application, resulting in an unnatural finish.

[0020] In one embodiment of the present disclosure, at least one of the first and second components of the apply-type film-forming agent contains 0.01% to 1.5% by weight of pigment-grade particles with a refractive index of 2.0 or greater. The inventors discovered that apply-type film-forming agents containing such high-refractive-index pigment-grade particles can be applied thicker than conventional cosmetics to fill pores and other recessed defects, as shown in Figure 1(c), and therefore can provide excellent correction of recessed defects even when the amount of pigment-grade particles is low. This effect is believed to be due to the high-refractive-index pigment-grade particles being arranged in a manner that allows for nearly specular reflection of light in the film that fills the recesses. Furthermore, because the amount of pigment-grade particles in the film is relatively low and the film applied to the skin is crosslinked, it is unlikely to smudge like conventional cosmetics, and therefore the formed film appears natural. Note that the recessed defects (pores) appear white in the simulation results in Figures 1(b) and 1(c), this is to make the location and shadow of the recessed defects easier to see. In an actual film, if the color of the film is adjusted using a coloring material, this white portion can be made less noticeable.

[0021] Furthermore, when a typical cosmetic is applied to the skin, the pigment-grade particles become fluid due to the influence of body temperature, etc., and as a result, they are not fixed in the layer formed by the cosmetic and may migrate to the depths of depression defects over time, etc. Therefore, even if a cosmetic contains high-refractive-index pigment-grade particles at a low concentration and can be applied thickly, it is thought that such a cosmetic would not be able to fully exhibit the effect of correcting depression defects and the natural finish performance.

[0022] On the other hand, the film produced by the paint-on film-forming agent according to one embodiment of the present disclosure is a film having a crosslinked structure formed by a first agent containing a crosslinkable component that constitutes the film and a second agent containing a catalyst that crosslinks the crosslinkable component. As a result, the pigment-grade particles contained in the film are fixed in a uniformly dispersed state within the film, which is believed to be more effective at correcting recess defects and providing a more natural finish than conventional cosmetics such as those described above.

[0023] For example, conventional cosmetics with pore-correcting properties have also had the problem of peeling off when applied to the skin due to sweat or rubbing. The apply-type film-forming agent of the present disclosure can form a film by applying the agent to the skin and crosslinking it, and the resulting crosslinked film is more resistant to peeling off due to rubbing than films obtained by applying conventional cosmetics to the skin. Therefore, it is believed that the apply-type film-forming agent according to one embodiment of the present disclosure can also contribute to solving the peeling off problem that conventional cosmetics have.

[0024] Furthermore, when conventional cosmetics are to be removed from the skin, it is necessary to wash the skin off using a cleanser or the like. On the other hand, the film formed by the apply-type film-forming agent according to one embodiment of the present disclosure has a crosslinked structure and therefore has superior film strength compared to films that do not have a crosslinked structure. As a result, unlike films formed by conventional cosmetics, this film has the advantage of being easily peelable from the skin.

[0025] The definitions of terms used in this disclosure are as follows:

[0026] In this disclosure, "viscosity" refers to a measure of the resistance of a fluid to being deformed by either shear stress or tensile stress. For example, the viscosity of the first and second parts of a paint-on film-forming agent affects the thickness, spreadability, and uniformity and / or evenness of the layer formed on a substrate. Viscosity can be measured using dynamic viscosity (also known as absolute viscosity, typical units are Pa s, poise, P, cP) or kinematic viscosity (typical units are cm 2 / s, Stokes, St, or cst), where kinematic viscosity is dynamic viscosity divided by the density of the measured fluid. Viscosity ranges for the components disclosed herein are generally provided by each component supplier in units of kinematic viscosity (e.g., cst) measured using a rheometer or a Cannon-Fenske tube viscometer, although fluid viscosity can also be measured using, for example, a rheometer (e.g., a linear shear rheometer or a dynamic shear rheometer) or a viscometer (a viscometer, also called a capillary viscometer or a rotational viscometer).

[0027] In the present disclosure, "crosslinking" also encompasses the concept generally referred to as "curing."

[0028] In the present disclosure, the term "target portion" refers to a portion where correction of a recess defect is desired to occur.

[0029] In the present disclosure, "correction of depression defects" refers to the fact that depression defects in the skin become less noticeable after application of a coating made from the apply-type film-forming agent of the present disclosure compared to before application, or that such depression defects are concealed. In the present disclosure, "depression defects" refer to depression-shaped imperfections on the body (e.g., pores, skin grooves, wrinkles, scars, etc.). Here, "depression defects on the body" can refer, for example, to depressions on the body that bother the subject, depressions on the body that the subject feels they would like to correct, or depressions on the body of the subject that a person skilled in the art, such as a dermatologist, esthetician, or plastic surgeon, believes should be corrected. The maximum depth of the depression from the skin surface is not particularly limited, and can be, for example, 50 μm or more, 80 μm or more, 100 μm or more, 150 μm or more, or 200 μm or more. There is no particular upper limit to the maximum depth, and it can be, for example, 2 mm or less, 1.5 mm or less, 1 mm or less, 800 μm or less, 500 μm or less, or 300 μm or less.

[0030] In this disclosure, the term "pigment-grade" refers to a size that allows the particles to function as a pigment. Pigment-grade particles can be distinguished from particles other than pigment-grade particles, for example, by their size. For example, the size of pigment-grade particles can be defined by an average particle diameter calculated by static light scattering, and such a size can be, for example, 100 nm or more, 150 nm or more, 200 nm or more, 250 nm or more, 300 nm or more, 350 nm or more, or 400 nm or more, and can be 800 nm or less, 700 nm or less, 600 nm or less, 500 nm or less, 400 nm or less, or 300 nm or less. Therefore, for example, even among titanium dioxide particles of the same type, titanium dioxide particles with an average particle diameter of 300 nm can be treated as pigment-grade particles, while titanium dioxide particles with an average particle diameter of 80 nm can be treated as ultraviolet scattering particles, for example.

[0031] <<Apply-on Film-Forming Agent>> In one embodiment of the present disclosure, the apply-on film-forming agent (sometimes simply referred to as "former") comprises, for example, a first agent containing a crosslinkable component that forms a film, and a second agent containing a catalyst that crosslinks the crosslinkable component. At least one of the first agent and the second agent contains 0.01% by weight or more and less than 1.5% by weight of pigment-grade particles having a refractive index of 2.0 or more. According to one embodiment of the present disclosure, the apply-on film-forming agent has an excellent correction effect for depression defects such as pores, and therefore can be suitably used for depression defects in the skin, particularly for pore correction.

[0032] In some embodiments, the application performance of the apply-type film-forming agent can be evaluated by viscosity using a Brookfield viscometer (Vismetron, manufactured by Shibaura Systems Co., Ltd.). The viscosity of the first and second parts of the apply-type film-forming agent according to an embodiment of the present disclosure immediately after preparation, measured under conditions of 25°C and 60 rpm (rotor No. 3 or No. 4), is, 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. The viscosity can be 1,000,000 mPa·s or more, 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. In particular, from the viewpoints of smooth application performance and suppression of dripping from the target site, the first and second parts of the apply-type film-forming agent preferably have a viscosity of 20,000 mPa·s or less, 15,000 mPa·s or less, or 10,000 mPa·s or less immediately after preparation, and preferably have a viscosity of 3,000 mPa·s or more, 5,000 mPa·s or more, or 7,000 mPa·s or more. From the viewpoint of thick application (i.e., obtaining a film with a thickness of, for example, 50 μm or more), at least one of the first and second parts of the apply-type film-forming agent, preferably the first part, preferably has a viscosity of 10,000 mPa·s or more, 11,000 mPa·s or more, or 12,000 mPa·s or more immediately after preparation. In this case, there is no particular upper limit to the viscosity, and it can be, for example, 100,000 mPa·s or less, 80,000 mPa·s or less, 50,000 mPa·s or less, or 30,000 mPa·s or less.

[0033] In some embodiments, the viscosity of the first and second parts of the paint-on film-forming agent according to one embodiment of the present disclosure after two weeks, measured at 25°C and 60 rpm (rotor No. 3), is preferably 50,000 mPa·s or less, 30,000 mPa·s or less, or 15,000 mPa·s or less, and is preferably 5,000 mPa·s or more, 7,000 mPa·s or more, or 10,000 mPa·s or more, from the viewpoints of smooth application performance and suppression of dripping from the target area.

[0034] In another embodiment, the paint-on film former (sometimes simply referred to as a "former") includes, for example, a powder as described below. In this embodiment, the powder may be included in the first agent, may be included in the second agent, or may be included in both the first and second agents. The powder may include pigment-grade particles (sometimes simply referred to as "pigment-grade particles") having a refractive index of 2.0 or higher. The powder may include particles different from the pigment-grade particles.

[0035] In this embodiment, the paint-type film-forming agent may also contain an unsaturated organopolysiloxane. When the unsaturated organopolysiloxane and the powder are contained in the same system (e.g., the first or second agent), the system containing the unsaturated organopolysiloxane and the powder may further contain a silicone surfactant. This can improve the dispersibility of the powder.

[0036] <First Agent> In one embodiment of the present disclosure, the paint-on film-forming agent includes a first agent that includes a crosslinkable reactive component that forms a film.

[0037] As described above, in one embodiment, the first agent may contain the above-mentioned pigment-grade particles having a refractive index of 2.0 or greater (sometimes simply referred to as "pigment-grade particles"). The first agent contains a crosslinkable reactive component that forms a film, and can form a final film. Therefore, when the first agent contains such pigment-grade particles, the effect of correcting recess defects and the performance of a natural finish can be further improved.

[0038] (Pigment-grade particles having a refractive index of 2.0 or more) From the viewpoint of correcting recess defects and achieving a natural finish, the refractive index of the pigment-grade particles is preferably 2.0 or more, 2.1 or more, 2.2 or more, 2.3 or more, or 2.4 or more, and is preferably 3.0 or less, 2.9 or less, or 2.8 or less. Here, the refractive index of the pigment-grade particles can be determined, for example, in accordance with JIS K 0062:1992.

[0039] When the first agent contains such pigment-grade particles, the blending amount thereof is preferably 0.01% by mass or more, or 0.02% by mass or more, more preferably 0.03% by mass or more, 0.04% by mass or more, or 0.05% by mass or more, relative to the entire first agent, from the viewpoint of the effect of correcting recess defects and natural finish performance, and is preferably less than 1.5% by mass, 1.3% by mass or less, 1.0% by mass or less, 0.8% by mass or less, 0.5% by mass or less, 0.3% by mass or less, 0.1% by mass or less, 0.09% by mass or less, 0.08% by mass or less, or 0.07% by mass or less.

[0040] The pigment-grade particles are not particularly limited as long as they have a refractive index of 2.0 or higher. Examples of pigment-grade particles include at least one selected from the group consisting of titanium oxide particles, iron oxide particles, magnesium oxide particles, zinc oxide particles, calcium oxide particles, calcium phosphate particles, calcium carbonate particles, aluminum oxide particles, aluminum hydroxide particles, barium sulfate particles, pearlescent pigments, and talc. Among these, titanium oxide particles are preferred from the viewpoints of correcting recess defects and achieving a natural finish. The pigment-grade particles can be used alone or in combination.

[0041] Here, in the present disclosure, the term "pearlescent pigment" refers to particles that exhibit luster. Pearlescent pigments typically have a flat, flake-like or scaly morphology. Examples of pearlescent pigments include titanium mica (titanium mica), iron oxide-coated titanium mica, carmine-coated titanium mica, carmine- and ferric iron oxide-coated titanium mica, iron oxide- and carmine-treated titanium mica, ferric iron oxide-treated titanium mica, iron oxide- and ferric iron oxide-treated titanium mica, chromium oxide-treated titanium mica, black titanium oxide-treated titanium mica, acrylic resin-coated aluminum powder, silica-coated aluminum powder, titanium oxide-coated mica, titanium oxide-coated bismuth oxychloride, titanium oxide-coated talc, colored titanium oxide-coated mica, titanium oxide-coated synthetic mica, titanium oxide-coated silica, titanium oxide-coated alumina, titanium oxide-coated glass powder, polyethylene terephthalate-polymethyl methacrylate laminated film powder, bismuth oxychloride, fish scale foil, iron oxide-coated titanium oxide-coated mica such as red iron oxide-coated titanium oxide-coated mica, and hollow titanium oxide powder having silica sandwiched between the mica and titanium oxide coating layer.

[0042] As the pearlescent pigment, a colorless pearlescent pigment can also be used. As such a pearlescent pigment, a known transparent pearlescent pigment (transparent luster pigment) can be used. For example, a pearlescent pigment can be used in which a coating made of a high refractive index material such as titanium oxide is formed on the surface of glass particles as a base material.

[0043] The pigment-grade particles may be subjected to a hydrophobic treatment. Hydrophobically treated pigment-grade particles (hydrophobic pigment-grade particles) are more likely to be dispersed uniformly in the coating, which can further improve the effect of correcting recess defects and the natural finish performance.

[0044] The hydrophobic treatment of pigment-grade particles is not particularly limited, and may be any treatment that modifies the surface of such particles with an organic compound to make them hydrophobic, such as silicone-based or silane-based treatments using methylhydrogenpolysiloxane, dimethylpolysiloxane (dimethicone), alkylsilane, etc.; fluorine-based treatments using perfluoroalkyl phosphate esters, perfluoroalcohols, etc.; titanate-based treatments using alkyl titanates, etc.; amino acid treatments using N-acylglutamic acid, etc.; and other treatments such as lecithin treatment, metal soap treatment, fatty acid treatment, and alkyl phosphate ester treatment. The hydrophobic treatments may be used alone or in combination. Furthermore, the hydrophobic treatment may be carried out using a hydrophobic treatment agent.

[0045] Examples of silicones usable as hydrophobic treatment agents include known silicones having a hydrogen-silicon bond, such as methylhydrogenpolysiloxane (dimethicone / methicone) copolymer. Other examples include triethoxysilylethylpolydimethylsiloxyethyldimethicone and triethoxysilylethylpolydimethylsiloxyethylhexyldimethicone, which have an alkoxy group-silicon bond as a reactive group. Dimethylpolysiloxanes can also be used.

[0046] Examples of the silane-based treatment agent include a silylating agent having an organic group introduced therein and a silane coupling agent, such as triethoxycaprylylsilane.

[0047] Examples of titanate-based treatment agents include titanium coupling agents such as alkyl titanates, pyrophosphate-type titanates, phosphorous-type titanates, and amino acid-type titanates.

[0048] In some embodiments, the first agent of the present disclosure contains at least one crosslinkable component selected from the group consisting of a first unsaturated organopolysiloxane and a first hydride-functionalized polysiloxane. From the viewpoint of obtaining a good coating, when the first agent contains only the first unsaturated organopolysiloxane of the first unsaturated organopolysiloxane and the first hydride-functionalized polysiloxane, the second agent in the forming agent of the present disclosure preferably contains the second hydride-functionalized polysiloxane. Also, when the first agent contains only the first hydride-functionalized polysiloxane of the first unsaturated organopolysiloxane and the first hydride-functionalized polysiloxane, the second agent preferably contains the second unsaturated organopolysiloxane. From the viewpoint of obtaining a better coating, it is preferable that the first agent contains both the first unsaturated organopolysiloxane and the first hydride-functionalized polysiloxane.

[0049] The dosage form of the first agent is not particularly limited, and may be, for example, a single-phase system composed of an oil phase, a non-emulsified oil-in-water or water-in-oil two-phase system, or a two-phase system composed of an oil-in-water emulsion composition or a water-in-oil emulsion composition. Here, a single-phase system composed of an oil phase is typically an anhydrous form. In the present disclosure, "anhydrous" not only refers to a composition that does not contain water, but also refers to a low water content, i.e., 10% by mass or less, 5% by mass or less, 2% by mass or less, 1% by mass or less, 0.1% by mass or less, or 0.01% by mass or less. Furthermore, a non-emulsified two-phase system may include a water-in-oil composition in which water droplets are forcibly dispersed in an oil-containing dispersion medium by shaking a liquid in a state where the water and oil have separated, or an oil-in-water composition in which oil droplets are forcibly dispersed in a water-containing dispersion medium.

[0082] <Second Agent> The second agent constituting the apply-type film-forming agent of the present disclosure contains a catalyst that crosslinks the crosslinkable component in the first agent. The second agent of the present disclosure may contain pigment-grade particles having a refractive index of 2.0 or greater, as in the first agent. When both the first and second agents contain such pigment-grade particles in an amount of 0.01% by mass or greater but less than 1.5% by mass, the pigment-grade particles are more likely to be located near the surface of the coating, making it easier for light incident on the coating to be reflected near the surface, thereby further improving the effect of correcting recess defects. Furthermore, when the second agent contains an unsaturated organopolysiloxane (second unsaturated organopolysiloxane), the pigment-grade particles are more likely to be located near the surface of the coating and are more likely to be fixed near the surface, thereby further improving the effect of correcting recess defects.

[0083] (Catalyst) The catalyst is not particularly limited, and may be, for example, any substance capable of causing, promoting, or initiating a physical and / or chemical crosslinking reaction of the unsaturated organopolysiloxane and hydride-functionalized polysiloxane, which are crosslinkable reactive components constituting the coating. The catalyst may or may not undergo permanent physical and / or chemical changes during or at the end of the process.

[0084] Examples of catalysts include, but are not limited to, metal catalysts that can initiate and / or accelerate crosslinking at or below body temperature, such as Group VIII metal catalysts, for example, platinum catalysts, rhodium catalysts, palladium catalysts, cobalt catalysts, nickel catalysts, ruthenium catalysts, osmium catalysts, and iridium catalysts, and Group IVA metal catalysts, for example, germanium catalysts and tin catalysts.

[0088] Among these catalysts, platinum catalysts are more preferred, and platinum divinyltetramethyldisiloxane complexes (sometimes referred to as "platinum divinyldisiloxanes") are particularly preferred.

[0089] The amount of catalyst in the second agent is not particularly limited and may be appropriately adjusted depending on the required coating performance, etc. For example, the amount of catalyst may be 0.001% by mass or more, 0.005% by mass or more, or 0.010% by mass or more, and 5.0% by mass or less, 3.0% by mass or less, 1.0% by mass or less, 0.10% by mass or less, or 0.050% by mass or less, relative to the total amount of the second agent. The catalyst can be used appropriately within such ranges.

[0090] The dosage form of the second agent of the present disclosure is not particularly limited, and may be, for example, a single-phase system constituted of an oil phase in an anhydrous form, a non-emulsified oil-in-water or water-in-oil two-phase system, or a two-phase system constituted in the form of an oil-in-water emulsion composition or a water-in-oil emulsion composition.

[0091] These formulations can be prepared by conventional methods using a catalyst and, optionally, known materials such as oil, emulsifier, and water, as described below.In addition, silicone oil can be used as the oil, and the first unsaturated organopolysiloxane and the first hydride-functionalized polysiloxane that can be used in the first agent described above can also be used as this silicone oil.In this case, in order to distinguish from the first unsaturated organopolysiloxane and the first hydride-functionalized polysiloxane in the first agent, the unsaturated organopolysiloxane and the hydride-functionalized polysiloxane in the second agent can be referred to as the second unsaturated organopolysiloxane and the second hydride-functionalized polysiloxane.

[0092] In one embodiment, the second unsaturated organopolysiloxane can have a viscosity of 50 to 165,000 cst at 25° C.

The lower limit of this viscosity is preferably 70 cst or more, 100 cst or more, 130 cst or more, or 150 cst or more.

[0093] <Optional Components> In the paint-type film-forming agent of the present disclosure, various components can be appropriately blended into the first agent and / or the second agent to the extent that the effects of the present disclosure are not adversely affected.

[0097] In some embodiments, at least one of the first and second parts of the apply-on film-forming agent of the present disclosure, preferably the first part, contains inorganic particles other than the pigment-grade particles described above, such as hydrophobic inorganic oxide particles. The use of hydrophobic inorganic oxide particles can increase the viscosity of the apply-on film-forming agent, thereby contributing to thick application and also to improving the strength of the film.

[0098] From the viewpoint of thickening the coating and obtaining good coating strength, the average particle diameter of inorganic particles (e.g., hydrophobic inorganic oxide particles) is preferably less than 100 nm, 70 nm or less, 50 nm or less, or 30 nm or less, more preferably 20 nm or less, 18 nm or less, or 16 nm or less, and particularly preferably 15 nm or less, 13 nm or less, 12 nm or less, 11 nm or less, 10 nm or less, less than 10 nm, or 9 nm or less. There is no particular restriction on the lower limit of the average particle diameter, and it can be, for example, 1 nm or more, 3 nm or more, or 5 nm or more. Here, the average particle diameter can mean, for example, the particle diameter (area-equivalent circle particle diameter) when converted into a circular particle having the same area as the projected area of ​​the particle observed with a transmission electron microscope. The area-equivalent circle particle diameter can be defined as the average value of 10 or more particles.

[0099] Examples of inorganic oxides constituting the hydrophobic inorganic oxide particles include zinc oxide, titanium oxide, aluminum oxide, and silicon oxide (e.g., fumed silica and anhydrous silica). Among these, at least one selected from the group consisting of silicon oxide, titanium oxide, and zinc oxide is preferred, and silicon oxide is more preferred.

[0100] The hydrophobic inorganic oxide particles can typically be inorganic oxide particles that have been hydrophobized with a surface treatment agent. The hydrophobization treatment is not particularly limited, and for example, from the viewpoint of thickening the coating and obtaining good coating strength, at least one treatment selected from the group consisting of dimethylsilylation and trimethylsilylation is preferred.

[0101] The amount of inorganic particles (e.g., hydrophobized inorganic oxide particles) added relative to the entire first or second agent can be, for example, 0.001% by mass or more, 0.01% by mass or more, 0.1% by mass or more, 0.5% by mass or more, 1.0% by mass or more, 3.0% by mass or more, 5.0% by mass or more, or 7.0% by mass or more, and can be 25% by mass or less, 23% by mass or less, 20% by mass or less, 18% by mass or less, 15% by mass or less, 13% by mass or less, or 10% by mass or less.

Oils may be used alone or in combination. Here, "volatile" refers to a volatile content of more than 5% when left at 105°C under atmospheric pressure for 3 hours. Such a volatile content may be defined as 10% or more, 20% or more, 40% or more, 50% or more, 60% or more, 80% or more, or 100%. Alternatively, the boiling point at 1 atmosphere (101.325 kPa) can be used as an indicator of volatility. This boiling point may be 250°C or less, 240°C or less, or 230°C or less, or 80°C or more, 100°C or more, 120°C or more, 150°C or more, or 160°C or more. In addition, in the present disclosure, "non-volatile" refers to a material that exhibits a volatile content of 5% or less when left at 105°C for 3 hours.

[0103] For example, silicone oils other than the above-mentioned unsaturated organopolysiloxanes and hydride-functionalized polysiloxanes can be used as the silicone oil. Examples of such silicone oils include linear silicones such as dimethylpolysiloxane (dimethicone), methylphenylpolysiloxane, and methylhydrogenpolysiloxane; and cyclic silicones such as diphenylsiloxyphenyltrimethicone, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane. Silicone oils are easily compatible with unsaturated organopolysiloxanes having phenyl groups and vinyl groups, and can therefore be suitably incorporated into the first and / or second agents containing unsaturated organopolysiloxanes having phenyl groups and vinyl groups.

[0104] The amount of oil (e.g., silicone oil) to be blended is not particularly limited, and can be appropriately blended depending on, for example, the type of formulation used, the required film strength, etc. The amount of oil (e.g., silicone oil) to be blended can be, for example, 5.0% by mass or more, 7.0% by mass or more, 10% by mass or more, 15% by mass or more, 20% by mass or more, 23% by mass or more, 25% by mass or more, 27% by mass or more, or 30% by mass or more relative to the total of the first or second agent, and can be 60% by mass or less, 57% by mass or less, 55% by mass or less, 50% by mass or less, 45% by mass or less, 40% by mass or less, 35% by mass or less, 30% by mass or less, 25% by mass or less, or 20% by mass or less. The oil can be used appropriately within such ranges.

[0105] (Emulsifier) ​​As the emulsifier, for example, anionic, cationic, amphoteric, or nonionic emulsifiers can be used. The emulsifiers can be used alone or in combination of two or more. Here, the emulsifier in the present disclosure refers to an agent having an emulsifying function (surface activity), and can also include agents generally referred to as surfactants.

[0106] Specifically, the emulsifier may be at least one selected from the group consisting of hydrocarbon surfactants, silicone surfactants, and amphiphilic powders.

[0107] Examples of hydrocarbon surfactants include polyoxyethylene alkyl ethers, polyoxyethylene steryl ethers, polyoxyethylene fatty acid esters, polyoxyethylene polyhydric alcohol fatty acid esters, polyoxyethylene hydrogenated castor oil, polyoxyethylene sorbitan fatty acid esters, glycol fatty acid esters, glycerin fatty acid esters, sorbitan fatty acid esters, sucrose fatty acid esters, and polyglycerin fatty acid esters.

[0108] Examples of silicone surfactants include polyether-modified silicones and alkyl-co-modified polyether-modified silicones.

[0109] The amount of emulsifier to be added is not particularly limited, and for example, from the viewpoint of emulsion stability, it can 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 relative to the total amount of the first or second agent. There is no particular upper limit to the amount of emulsifier to be added, and it can be, for example, 5.0% by mass or less, 4.0% by mass or less, 3.0% by mass or less, 2.0% by mass or less, 1.0% by mass or less, or 0.5% by mass or less. The emulsifier can be used appropriately within this range.

[0110] (Silicone-Based Surfactant) As described above, the apply-type film-forming agent may contain a powder. The powder may contain the pigment-grade particles having a refractive index of 2.0 or greater, as described above, or may be substantially free of such pigment-grade particles. When the powder contains the pigment-grade particles, the ratio of the mass of the pigment-grade particles to the mass of the apply-type film-forming agent may be 0.01% by mass or more but less than 1.5% by mass.

[0111] In some embodiments, when a powder is blended with an unsaturated organopolysiloxane in the paint-on film-forming agent of the present disclosure, the dispersibility of the powder can be improved by further blending a silicone surfactant into the system containing them. Note that, from the viewpoint that the dispersibility of the powder is improved by further including a silicone surfactant in the mixture of the unsaturated organopolysiloxane and the powder, the ratio of the mass of the pigment-grade particles to the mass of the paint-on film-forming agent can be less than 0.01% by weight or more than 1.5% by weight.

[0112] When considering the dispersibility of a powder, it is common to select a dispersant that acts on the powder (for example, a dispersant that exerts a steric hindrance effect on the surface of the powder). However, unlike such common dispersants, the silicone surfactant used in the forming agent of the present disclosure is believed to act not on the powder but on the unsaturated organopolysiloxane.

[0113] For example, as shown in Figure 2(a), when a powder and an unsaturated organopolysiloxane are blended in an oil phase, the unsaturated organopolysiloxane acts to aggregate the powder, which is thought to reduce the dispersibility of the powder. Therefore, even if a general dispersant that acts on powders is blended into such a system, it is thought that a sufficient dispersion effect will not be obtained.

[0114] On the other hand, the silicone surfactant incorporated into the forming agent of the present disclosure has excellent affinity with the unsaturated organopolysiloxane, which can act as a powder flocculating agent. Therefore, as shown in Figure 2(b), it is believed that the hydrophobic groups of this silicone surfactant interact with the unsaturated organopolysiloxane to disperse in the oil phase in a reverse micelle-like form. As a result, the powder flocculating action of the unsaturated organopolysiloxane is reduced, which is believed to improve the dispersibility of the powder in the forming agent. Here, the black bars of the silicone surfactant in Figure 2(b) represent hydrophobic groups, and the white spheres represent hydrophilic groups.

[0115] In some embodiments, the amount of silicone surfactant in the first or second agent of a powder-containing forming agent can be, for example, 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, 9.0% by mass or more, or 10% by mass or more, and 15% by mass or less, 13% by mass or less, 10% by mass or less, 8.0% by mass or less, 6.0% by mass or less, or 5.0% by mass or less, relative to the total amount of the first or second agent. The silicone surfactant can be used appropriately within such a range.

[0116] In some embodiments, the amount of silicone surfactant in the first or second agent of the powder-containing forming agent can be specified as a ratio relative to a total of 100 parts by mass of the powder, unsaturated organopolysiloxane, and silicone surfactant. In this case, the amount of silicone surfactant can be 1.0 parts by mass or more, 3.0 parts by mass or more, 5.0 parts by mass or more, 7.0 parts by mass or more, or 9.0 parts by mass or more, relative to a total of 100 parts by mass of the powder, unsaturated organopolysiloxane, and silicone surfactant, and can be 20 parts by mass or less, 17 parts by mass or less, 15 parts by mass or less, 13 parts by mass or less, or 10 parts by mass or less.

[0117] The silicone surfactants may be used alone or in combination.

[0118] As the silicone surfactant, for example, from the viewpoint of improving the dispersibility of powder, a silicone surfactant having an HLB value of 10.0 or less is preferred. Such an HLB value can be 9.0 or less, 8.0 or less, 7.0 or less, 6.0 or less, or 5.0 or less. There is no particular limitation on the lower limit of the HLB value, and it can be, for example, 0.1 or more, 0.5 or more, 1.0 or more, 1.5 or more, or 2.0 or more. In particular, from the viewpoint of improving the dispersibility of powder, the HLB value is preferably 0.1 or more and 7.0 or less. Here, "HLB" generally refers to a value indicating affinity to water and oil, and is a parameter known as the hydrophilic-lipophilic balance. The HLB value of a silicone surfactant can be easily determined by the Griffin method. Here, the HLB value according to the Griffin method can be determined by the following formula a: HLB value = 20 × sum of formula weights of hydrophilic moieties / molecular weight ... formula a

[0119] Specific examples of silicone surfactants that can improve the dispersibility of powders include polyglycerin-alkyl-co-modified silicones, carboxy-modified silicones, and polyether-modified silicones.

[0120] (Polyglycerin / Alkyl Co-Modified Silicone) Examples of polyglycerin / alkyl co-modified silicones include bisbutyldimethicone polyglyceryl-3 and cetyl PEG / PPG-10 / 1 dimethicone. Here, "PEG" and "PPG" refer to polyethylene glycol and polypropylene glycol, respectively.

[0121] (Carboxy-Modified Silicone) An example of the carboxy-modified silicone is carboxydecyltrisiloxane.

[0122] (Polyether-modified silicone) Examples of polyether-modified silicones include PEG-9 polydimethylsiloxyethyl dimethicone, PEG-10 dimethicone, PO / EO-modified silicone (e.g., PEG / PPG-19 / 19 dimethicone), and dimethicone / (PEG-10 / 15) crosspolymer. Here, "PO" and "EO" refer to propylene oxide and ethylene oxide.

[0123] Powder In some embodiments, the spreadable film-forming agent or cosmetic of the present disclosure contains a powder. The powder may be used alone or in combination of two or more types.

[0124] In some embodiments, the amount of powder blended varies and can be set appropriately depending on the intended use of the cosmetic. The amount of powder blended can be, for example, 3.0% by mass or more, 5.0% by mass or more, more than 5.0% by mass, 7.0% by mass or more, 8.0% by mass or more, 10% by mass or more, 15% by mass or more, 20% by mass or more, 25% by mass or more, or 30% by mass or more relative to the total amount of the apply-type film-forming agent (e.g., the first or second agent) or the cosmetic, and can be 50% by mass or less, 40% by mass or less, 30% by mass or less, 20% by mass or less, or 15% by mass or less. The amount of powder blended in the apply-type film-forming agent or the cosmetic can be appropriately set within these ranges.

[0125] In some embodiments, the amount of powder in a spread-type film-forming agent (e.g., the first or second agent) or a cosmetic can be specified as a percentage relative to 100 parts by mass of the total of the powder, unsaturated organopolysiloxane, and silicone surfactant. In this case, the amount of powder can be 10 parts by mass or more, 15 parts by mass or more, 20 parts by mass or more, 25 parts by mass or more, or 27 parts by mass or more, and can be 60 parts by mass or less, 55 parts by mass or less, 50 parts by mass or less, or 47 parts by mass or less, relative to 100 parts by mass of the total of the powder, unsaturated organopolysiloxane, and silicone surfactant.

[0126] In some embodiments, the powder is not particularly limited, and for example, spherical or non-spherical powders commonly used in the field of cosmetics can be used. The spreadable film-forming agent (e.g., the first or second agent) or cosmetic may contain only spherical powders, only non-spherical powders, or both spherical and non-spherical powders.

[0127] In some embodiments, the applied film-forming agent or cosmetic of the present disclosure contains a spherical powder. The size of the spherical powder is not particularly limited. For example, the average particle size of the spherical powder can be 0.01 μm or more, 0.05 μm or more, 0.1 μm or more, 0.5 μm or more, 1.0 μm or more, 3.0 μm or more, or 5.0 μm or more, and can be 50 μm or less, 30 μm or less, 20 μm or less, 15 μm or less, or 10 μm or less. The spherical powder can be used alone or in combination of two or more types, each having an average particle size within such range.

[0128] The average particle size can be defined as the average value of the diameter of the powder (particles) optically measured by dynamic light scattering, assuming that the powder has a spherical shape.

[0129] In some embodiments, the spreadable film-forming agent or cosmetic of the present disclosure contains a non-spherical powder. Non-spherical powder refers to powders that are not included in the spherical powders described above, and can be defined, for example, by aspect ratio. The aspect ratio of the non-spherical powder can be 1.2 or more, 1.5 or more, 2.0 or more, 2.5 or more, 3.0 or more, 5.0 or more, 7.0 or more, 10 or more, 15 or more, 20 or more, 25 or more, or 30 or more, and can be 200 or less, 170 or less, 150 or less, 120 or less, 100 or less, 70 or less, or 50 or less. Powders having aspect ratios within these ranges can be used alone or in combination of two or more types of non-spherical powder.

[0130] The aspect ratio can be calculated, for example, by microscopic observation, by extracting any 10 or more (e.g., 100) powder particles, measuring the longitudinal (surface) length of each powder and the transverse (thickness) length of each powder, and dividing the longitudinal length by the transverse length (i.e., longitudinal length / transverse length). The powder with the longest longitudinal length is selected, and the powder with the shortest transverse length is selected. The aspect ratio can be the average value of the aspect ratios of any 10 or more (e.g., 100) powder particles.

[0131] In some embodiments, the type of powder is not particularly limited, and for example, inorganic powders and / or organic powders can be used. The inorganic powders and organic powders can be used alone or in combination of two or more.

[0132] Examples of components constituting the inorganic powder include talc, kaolin, mica (e.g., sericite (sericite), muscovite, phlogopite, synthetic mica, synthetic iron phlogopite, lepidolite, and biotite), calcined talc, calcined mica (e.g., calcined sericite, calcined muscovite, and calcined phlogopite), vermiculite, magnesium carbonate, calcium carbonate, aluminum silicate, barium silicate, calcium silicate, magnesium silicate, strontium silicate, Ca / Al borosilicate, metal tungstate, magnesium, silica, alumina, zeolite, aluminum hydroxide, barium sulfate, calcined calcium sulfate (calcined gypsum), calcium phosphate, fluorapatite, hydroxyapatite, ceramic powder, metal soap (e.g., zinc myristate, calcium palmitate, and aluminum stearate), boron nitride, photochromic titanium oxide (titanium dioxide sintered with iron oxide), and reduced zinc white. Such powders may be blended as pigments other than coloring pigments for the purpose of increasing or reinforcing the volume of applied film-forming agents or cosmetics. Powders used for such purposes are sometimes called extender pigments.

[0133] In addition, inorganic pigments (sometimes referred to as "inorganic colored pigments") can also be used as the inorganic powder. Examples of inorganic pigments include inorganic white pigments (e.g., titanium dioxide, zinc oxide); inorganic red pigments (e.g., iron oxide (red iron oxide), iron titanate); inorganic brown pigments (e.g., γ-iron oxide); inorganic yellow pigments (e.g., yellow iron oxide, ochre); inorganic black pigments (e.g., black iron oxide, low-order titanium oxide); inorganic purple pigments (e.g., mango violet, cobalt violet); inorganic green pigments (e.g., chromium oxide, chromium hydroxide, cobalt titanate); and inorganic blue pigments (e.g., ultramarine, Prussian blue). Other examples include glitter powders. Examples of such glittering powders include pearl pigments (e.g., bismuth oxychloride, fish scale foil, titanium mica, titanium iron oxide-coated titanium mica, titanium low-titanium oxide-coated titanium mica, photochromic titanium mica, substrates using talc, glass, synthetic fluorine-containing phlogopite, silica, bismuth oxychloride, or the like instead of mica, coatings other than titanium oxide such as low-titanium oxide, colored titanium oxide, iron oxide, alumina, silica, zirconia, zinc oxide, cobalt oxide, and aluminum, and functional pearl pigments such as pearl pigments coated with resin particles, pearl pigments coated with aluminum hydroxide particles, pearl pigments coated with zinc oxide particles, and pearl pigments coated with barium sulfate particles); and metal powder pigments (e.g., aluminum powder and copper powder).

[0134] Examples of components constituting the organic powder include silicone elastomer, silicone, silicone resin-coated silicone elastomer, polyamide resin (e.g., nylon), polyolefin resin (e.g., polyethylene), polymethyl methacrylate, polystyrene, styrene-acrylic acid copolymer resin, benzoguanamine resin, fluororesin (e.g., polytetrafluoroethylene), starch (e.g., starch Al octenyl succinate), crosspolymers such as (HDI / trimethylol hexyl lactone) crosspolymer, (diphenyl dimethicone / vinyl diphenyl dimethicone / silsesquioxane) crosspolymer, and (IPDI / poly(1,4-butanediol)-14) crosspolymer, and cellulose.

[0135] Other examples of organic powders that can be used include organic pigments (sometimes referred to as "organic coloring pigments") and / or dyes. Examples of organic pigments include zirconium, barium, and aluminum lakes, specifically, Red No. 201, Red No. 202, Red No. 204, Red No. 205, Red No. 220, Red No. 226, Red No. 228, Red No. 405, Orange No. 203, Orange No. 204, Yellow No. 205, Yellow No. 401, and Blue No. 404, as well as Red No. 3, Red No. 104, Red No. 106, Red No. 227, Red No. 230, Red No. 401, Red No. 505, Orange No. 205, Yellow No. 4, Yellow No. 5, Yellow No. 202, Yellow No. 203, Green No. 3, and Blue No. 1.

[0136] Examples of pigments include natural pigments, specifically, for example, chlorophyll and β-carotene.

[0137] In some embodiments, the spreadable film-forming agent or cosmetic of the present disclosure contains a hydrophobic powder. The hydrophobic powder is suitable for dispersing the powder in an oil phase. The hydrophobic powder can be used alone or in combination of two or more types.

[0138] In the present disclosure, "hydrophobicity" refers to the ability to have low affinity for water. Hydrophobicity can be evaluated, for example, by placing 50 g of ion-exchanged water and 0.1 g of a powder to be evaluated in a transparent sealed container, storing the powder at 50°C for one day, and then visually observing the container. Specifically, a powder can be evaluated as "hydrophobic" when the majority of the powder to be evaluated (e.g., 50% or more of the powder to be evaluated) is present near the surface of the ion-exchanged water (e.g., within a region approximately 1 cm below the water surface). Furthermore, when the specific gravity of the powder to be evaluated is high (e.g., a specific gravity of 3.0 g / cm 3 More than 5.0 g / cm 3 In the above cases, "hydrophobicity" can be evaluated by the following method instead of the evaluation method. For example, when ion-exchanged water is dropped into a container filled with powder in an atmosphere of 25°C, if the water turns into droplets that roll on the surface, it can be evaluated as "hydrophobicity."

[0139] The hydrophobic powder can be obtained by treating the above-mentioned powder with, for example, a surface treatment agent capable of imparting hydrophobic properties.

[0140] Examples of such surface treatment agents include higher fatty acids, metal soaps, oils and fats, waxes, silicone compounds (e.g., carboxydecyltrisiloxane, dimethicone, acrylic-silicone graft copolymers), fluorine compounds, hydrocarbons, surfactants other than the silicone surfactants described below, dextrin fatty acid esters (e.g., dextrin palmitate), polyglycerin fatty acid esters (e.g., polyglyceryl-2 tetraisostearate), amino acids (lauroyl lysine), distearyldimonium chloride, and distearyldimonium chloride. Here, the higher fatty acid may be a saturated or unsaturated fatty acid having 6 or more carbon atoms, and specific examples include myristic acid and stearic acid. The surface treatment agents can be used alone or in combination of two or more.

[0141] In some embodiments, when the cosmetic preparation of the present disclosure contains a powder, an unsaturated organopolysiloxane, and a silicone surfactant, the powder, the unsaturated organopolysiloxane, and the silicone surfactant can be the same as those used in the above-mentioned paint-on film-forming agent.

[0142] (Water) The water is not particularly limited, and for example, water used in cosmetics or quasi-drugs can be used, such as ion-exchanged water, distilled water, ultrapure water, and tap water.

[0143] The amount of water to be added is not particularly limited, and can be adjusted appropriately depending on, for example, the type of formulation to be used.

[0144] <<Method of Using a Coat-in-Type Film-Forming Agent>> The method of using the coat-in-type film-forming agent of the present disclosure is not particularly limited and may include, for example, any of the following steps. Note that, since such a method can also be used to apply makeup to the face, for example, the method can also be referred to as a cosmetic method. Furthermore, the method of using the coat-in-type film-forming agent of the present disclosure does not include methods of surgery, treatment, or diagnosis on humans: Applying a first agent to a target site (e.g., a body surface) to form a first agent layer, and then applying a second agent on the first agent layer to form a film having a thickness of 50 μm or more; or Applying a second agent to a target site (e.g., a body surface) to form a second agent layer, and then applying the first agent on the second agent layer to form a film having a thickness of 50 μm or more; or Mixing the first agent and the second agent to prepare a mixture, and then applying the mixture to the target site (e.g., a body surface) to form a film having a thickness of 50 μm or more.

[0145] From the viewpoint of the effect of correcting recess defects and the natural finish performance, a preferred method of use is to apply the first agent to the target area to form a first agent layer, and then apply the second agent on this first agent layer and crosslink it to form a film. Here, the materials described above can be used in the same way for the first agent and the second agent.

[0146] This method may be performed in one go, or may be performed multiple times (e.g., two or more times, or three or more times) on the formed film. When performed multiple times, the method may include, for example, any of the following operations. According to this method, even if the viscosity of the paint-on film-forming agent is low, it is possible to form a film with a thickness of 50 μm or more: a procedure of applying a first agent to the formed film to form a first agent layer, and then applying a second agent on the first agent layer to further form a film, or a procedure of applying a second agent to the formed film to form a second agent layer, and then applying the first agent on the second agent layer to further form a film, or a procedure of mixing the first agent and the second agent to prepare a mixture, and then applying the mixture to the formed film to further form a film.

[0147] The paint-on film-forming agent of the present disclosure can form a film having a thickness of 50 μm or more. Therefore, the paint-on film-forming agent of the present disclosure can also be referred to as a paint-on film-forming agent for forming a film having a thickness of 50 μm or more.

[0148] From the viewpoint of the effect of correcting recess defects and natural finish performance, the thickness of the coating can be 50 μm or more, 70 μm or more, 90 μm or more, 100 μm or more, 110 μm or more, 120 μm or more, 130 μm or more, 140 μm or more, or 150 μm or more. There is no particular upper limit to the thickness, and it can be, for example, 300 μm or less, 270 μm or less, 250 μm or less, 230 μm or less, 200 μm or less, 170 μm or less, or 150 μm or less. The thickness of the coating can be appropriately adopted within such a range. Here, the thickness can be defined as the average value calculated by measuring the thickness of any portion of the coating peeled from the target area five times using a high-precision Digimatic Micrometer (MDH-25MB, manufactured by Mitutoyo Corporation). The surface of the film peeled off from the target area has minute irregularities associated with pores and other concave defects, but the film thickness obtained using this measurement method will allow the film to penetrate into the pores and other concave defects and have the effect of correcting those areas.

[0149] In some embodiments, a cosmetic may be applied to a target site before applying the first agent, the second agent, or a mixture comprising the first agent and the second agent to the target site; a first agent may be applied to a target site to form a first agent layer, a cosmetic may be applied on the first agent layer, and then the second agent may be applied to cover the cosmetic; a second agent may be applied to a target site to form a second agent layer, a cosmetic may be applied on the second agent layer, and then the first agent may be applied to cover the cosmetic; or a film may be formed, and then a cosmetic may be applied to the film. In some embodiments, the spread-type film-forming agent of the present disclosure can be used as a base agent or a base cosmetic.

[0150] The cosmetic is not particularly limited, and examples thereof include skin care cosmetics such as serum, lotion, and emulsion, sunscreen cosmetics (sunscreen cosmetics), base cosmetics, or makeup cosmetics such as foundation, gloss, lipstick, eye shadow, and nail polish, or cosmetics that combine two or more of the functions of these cosmetics.

[0151] The cosmetic may be a powder cosmetic. In this case, the ratio of the mass of water to the mass of the entire cosmetic (sometimes referred to as moisture content) may be less than 50% by mass, less than 40% by mass, less than 30% by mass, less than 20% by mass, 15% by mass or less, 10% by mass or less, 5% by mass or less, 3% by mass or less, 2% by mass or less, 1% by mass or less, or less than 1% by mass. There is no particular restriction on the lower limit of this ratio, and it may be, for example, 0% by mass or more, more than 0% by mass, or 1% by mass or more.

[0152] The moisture content is measured by the heat loss method. The moisture content is measured, for example, using a heat-drying moisture meter (MS-70, manufactured by A&D Co., Ltd.). More specifically, when the powder cosmetic does not substantially contain any substance with a boiling point lower than that of water (for example, when the ratio of the mass of substances with a boiling point lower than that of water to the mass of the powder cosmetic is less than 5% by mass), the moisture content is measured by the heat loss method. On the other hand, when the powder cosmetic contains a predetermined amount or more of a substance with a boiling point lower than that of water, the moisture content may be measured by near-infrared spectroscopy. An example of the predetermined amount is 5% by mass.

[0153] In some embodiments, the method of using the topical film-forming agent of the present disclosure can also be used as a cosmetic treatment. For example, when skin is exposed to dryness, moisture is unknowingly lost, and the stratum corneum on the skin surface may not be able to maintain its moisture content. When the skin lacks moisture, it is unable to effectively produce the moisturizing components (natural moisturizing factors (NMFs)) that it produces itself. As a result, the barrier function and moisturizing function of the skin surface are weakened, making the skin more susceptible to damage, which is thought to lead to a loss of moisture and skin roughness.

[0154] On the other hand, for example, when a film made from the applied film-forming agent of the present disclosure is applied to the skin, the occlusion effect of the film (the effect of preventing moisture loss from the skin) can effectively moisturize the skin. As a result, for example, the skin's own production function of moisturizing ingredients is improved, and abnormalities in turnover in the stratum corneum are also improved, making skin problems such as roughness less likely to occur and improving the cosmetic effect. Note that the term "cosmetic method" refers to applying the applied film-forming agent of the present disclosure to a target site to form a film and improve the condition of the target site (e.g., the face), and is different from methods of surgery, treatment, or diagnosis of humans.

[0155] There are no particular limitations on the method for applying the first or second agent to the target area, the cosmetic application layer, or the first or second agent layer, and for example, methods such as spreading with fingers, spray application, and transfer can be used.

[0156] Furthermore, for example, when the first agent and / or the second agent are separated into water and oil, it is preferable to shake these agents to forcibly form a two-phase system (oil-in-water type or water-in-oil type) from the viewpoint of the crosslinking reactivity between the first agent and the second agent, the dispersibility of pigment-grade particles in the coating, etc.

[0157] <Target Area> The topical film-forming agent of the present disclosure can be applied to any part of the body, for example, the surface of the skin (body surface). The topical film-forming agent of the present disclosure can be appropriately applied to, for example, the head, face (lips, eyes, nose, cheeks, forehead, etc.), neck, ears, hands, arms, legs, feet, chest, abdomen, back, buttocks, nails, etc. Here, skin also includes nails, which have hardened due to changes in the keratin layer of the skin's epidermis.

[0158] <Kit Including a Coating-Type Film-Forming Agent> The coating-type film-forming agent of the present disclosure can be provided as a kit including the first and second agents that constitute the coating agent. In addition to the first and second agents, the kit may also include optional components such as components that facilitate application of the first agent to the target site, or the various cosmetics described above, or the kit may be used in combination with optional components.

[0159] Examples of optional components include an instruction manual, a spatula-shaped applicator, a brush, a cotton swab, a cutter, scissors, the various cosmetics described above, a remover for removing the formed film from the target site, a mirror, etc. Here, the "instruction manual" can include not only a general instruction manual attached in the form of a document to the kit, but also, for example, an instruction manual printed on a packaging container that contains the kit or a packaging container such as a tube for injecting the first agent, etc.

[0160] In some embodiments, the kit may be configured so that the first and second agents are not in contact with each other, for example, by containing the first and second agents in separate containers or in separate compartments of a container having two or more compartments, and the contained agents may be configured to be applied one at a time or to be mixed together before or at the time of use.

[0161] In one embodiment, the kit can be used in combination with a remover for removing the formed film from the target site. Here, "use in combination" includes using the kit and the remover as an integrated unit, i.e., including the remover in the kit, or using the kit and the remover separately. For example, since it is possible to provide a spreadable film-forming agent and remover that are optimal for each individual, it is preferable to use a kit including a spreadable film-forming agent in combination with a separate remover.

[0162] <Remover> The film formed on the target site by the applied film-forming agent of the present disclosure can be suitably removed from the target site using the specific remover shown below. When the specific remover of the present disclosure is used, the strength of the film is not reduced, so the film can be peeled off from the target site in one go without breaking. For example, when removing conventional sunscreen cosmetics from the skin after application, it is necessary to wash them off with a cleanser or the like. In contrast, the film formed by the applied film-forming agent of the present disclosure does not require such work, and the film exhibiting UV protection performance can be more easily peeled off from the target site (e.g., skin).

[0163] In some embodiments, a remover suitable for use in removing a film formed by the paint-on film-forming agent of the present disclosure contains at least one oil selected from the group consisting of a hydrocarbon oil having a weight-average molecular weight of 300 or more and 800 or less, and a polar oil having a weight-average molecular weight of 260 or more and 400 or less. From the viewpoint of effectively removing the film, it is preferable to use such a hydrocarbon oil and a polar oil in combination.

[0164] (Hydrocarbon Oil) From the viewpoint of suitably removing the film, the weight average molecular weight of the hydrocarbon oil is preferably 320 or more or 350 or more, and more preferably 380 or more, and is preferably 750 or less or 700 or less, and more preferably 690 or less. The hydrocarbon oils may be used alone or in combination of two or more kinds.

[0165] The type of hydrocarbon oil is not particularly limited, and examples thereof include liquid paraffin (mineral oil), olefin oligomers and hydrogenated products thereof (for example, hydrogenated polydecene), and squalane.

[0166] The amount of hydrocarbon oil blended is not particularly limited, and from the viewpoint of effectively removing the film, it can be, for example, 1.0 mass% or more, 5.0 mass% or more, 10 mass% or more, 20 mass% or more, or 30 mass% or more relative to the total amount of the composition constituting the remover. The upper limit of the blended amount is not particularly limited, and can be, for example, 100 mass% or less, less than 100 mass%, 80 mass% or less, 70 mass% or less, 60 mass% or less, or 50 mass% or less.

[0167] (Polar Oil) From the viewpoint of favorable film removal, the weight average molecular weight of the polar oil is preferably 265 or more or 270 or more, and preferably 390 or less, 380 or less, or 370 or less. From the viewpoint of favorable film removal, the IOB value of the polar oil is preferably 0.12 or more or 0.13 or more, and preferably 1.48 or less, 1.47 or less, or 1.46 or less. The polar oils can be used alone or in combination of two or more.

[0168] The type of polar oil is not particularly limited, and examples thereof include ester oils, such as isopropyl myristate (IOB value = 0.18), ethylhexyl ethylhexanoate (IOB value = 0.20), alkyl (C12-15) benzoate (IOB value = 0.18), diethylhexyl succinate (IOB value = 0.32), neopentyl glycol diheptanoate (IOB value = 0.33), caprylic / capric triglyceride (IOB value = 0.28), PPG-3 dipivalate (IOB value = 1.46), and octyl palmitate (IOB value = 0.13).

[0169] The amount of polar oil is not particularly limited, and for example, from the viewpoint of favorable removal of the film, it can be 1.0 mass% or more, 5.0 mass% or more, 10 mass% or more, 15 mass% or more, or 20 mass% or more relative to the total amount of the composition constituting the remover. The upper limit of the amount is not particularly limited, and can be, for example, 100 mass% or less, less than 100 mass%, 80 mass% or less, 70 mass% or less, 60 mass% or less, or 50 mass% or less.

[0170] (Optional Components) The remover of the present disclosure can be appropriately blended with various components as long as they do not adversely affect the film removal effect. Examples of the various components include surfactants (emulsifiers), moisturizers, thickeners, water-soluble polymers, oil-soluble polymers, film-forming agents, higher fatty acids, sequestering agents, lower alcohols, higher alcohols, polyhydric alcohols, denatured alcohols, various extracts, sugars, amino acids, organic amines, polymer emulsions, chelating agents, UV absorbers, pH adjusters, skin nutrients, vitamins, water-soluble agents applicable to pharmaceuticals, quasi-drugs, cosmetics, etc., buffers, anti-fading agents, antioxidants, preservatives, dispersants, propellants, fillers, pigments, dyes, colorants, fragrances, water, and other oils other than those mentioned above. The optional components can be used alone or in combination of two or more.

[0171] The remover of the present disclosure may contain oils other than the above-mentioned hydrocarbon oils and polar oils.However, silicone oils may reduce the strength of the film, and as a result, may reduce the film removal performance.Therefore, from the viewpoint of effectively removing the film, the blending amount of silicone oil is preferably 10 mass% or less, 5.0 mass% or less, 1.0 mass% or less, 0.5 mass% or less, or 0.1 mass% or less relative to the total amount of the composition constituting the remover, and more preferably, silicone oil is not contained in the composition constituting the remover.

[0172] <Method of Using Remover> There are no particular limitations on how the remover can be used. In general, the remover can be applied to part or all of the film formed on the target area and then optionally rubbed. The film can then be removed by pulling it off with the fingers or the like.

[0173] The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these. Hereinafter, unless otherwise specified, the blending amounts are expressed in mass %. Furthermore, the evaluation methods described in the examples are not limited to the forming agents and films formed by the forming agents described in the examples, but can also be used for the above-mentioned forming agents and films formed by the forming agents.

[0174] <Evaluation Test 1> The following tests were carried out using the test samples obtained by the manufacturing methods described below. The results are shown in Table 2.

[0175] <Test for Correction Effect of Depression Defects> Bioskin (a new age-specific cheek skin model, age group 30s, manufactured by Beaulux Co., Ltd.), a commercially available high-performance artificial skin model, was prepared. The first and second agents of the test sample were applied to this Bioskin in order to form a film of a predetermined thickness. Under fluorescent lighting, the Bioskin was placed on a desk with the film side facing up. The film was observed from a position approximately 30 cm away from the film surface, with the line of sight at an angle of approximately 45 degrees to the film surface, and the correction effect of the depression defects was evaluated according to the following criteria. The results are shown in Tables 2 and 3. Here, ratings A to C are considered acceptable, and ratings D to E are considered unacceptable. Note that for Comparative Examples 1 to 3, no test for correction effect of depression defects was conducted because a film could not be formed: A: No shadow was observed around the depression defects (pores). B: Very slight shadow was observed around the depression defects (pores). C: A slight shadow was observed around the depression defects (pores). D: Shadows were clearly observed around the recessed defects (pores). E: Shadows were more clearly observed around the recessed defects (pores).

[0176] <Natural Finish Test> Bioskin (a new age-specific cheek skin model, age group 30s, manufactured by Beaulux Co., Ltd.), a commercially available high-performance artificial skin model, was prepared. The first and second agents of the test sample were applied to this Bioskin in order to form a film of a predetermined thickness. Under fluorescent lighting, the Bioskin was placed on a desk with the film surface facing up. The film was observed from a position approximately 30 cm away from the film surface, with the line of sight at an angle of approximately 45 degrees to the film surface, and the natural finish was evaluated according to the following criteria. The results are shown in Table 2. Here, ratings A to C are considered acceptable, and ratings D to E are considered unacceptable. Note that a natural finish test was not conducted for Comparative Examples 1 to 3, as no film could be formed, and Comparative Example 4 failed in correcting the recess defects: A: A natural finish was obtained. B: An almost (i.e., approximately 90%) natural finish was obtained. C: A generally (i.e., approximately 70%) natural finish was obtained. D: A somewhat unnatural finish was obtained. E: An unnatural finish was obtained.

[0177] <Film Formation Test> The film formed on the artificial skin in the above correction test was touched with a finger to check whether a film was formed that would not peel off when touched with a finger. In the table, if such a film was formed, it was marked as "passed", and if such a film was not formed, it was marked as "failed".

[0178] <Viscosity Evaluation Test> The viscosity of the first agent in the test sample immediately after preparation was measured using a Brookfield viscometer (Shibaura Systems Co., Ltd., Vismetron) at 25°C and 60 rpm (rotor No. 3 or No. 4). The results are shown in Tables 2 and 3.

[0179] Test Example 1 Each test sample in this test example was prepared according to the following method. In this test example, the effect of pigment-grade particles with a refractive index of 2.0 or higher in a paint-on film-forming agent was investigated. The results are shown in Table 2. In the table, "Mw" refers to the weight-average molecular weight. The thickness of the film in each example and comparative example is the average value calculated by measuring the thickness of any part of the film peeled from the artificial skin five times using a high-precision Digimatic Micrometer (MDH-25MB, manufactured by Mitutoyo Corporation).

[0180] Comparative Example 1 (First Agent) A first agent was prepared by uniformly mixing vinyl dimethicone (30.00 parts by mass) having a viscosity of 165,000 cst as the first unsaturated organopolysiloxane, volatile dimethicone (the remainder) as the oil component, hydrophobized pigment-grade titanium dioxide (0.05 parts by mass) as the pigment-grade particles, and silica silylate (10.00 parts by mass) as the hydrophobized inorganic oxide particles. Note that no hydride-functionalized polysiloxane was blended into this first agent.

[0181] (Second Agent) The ingredients in Table 1 were mixed uniformly to prepare a second agent 2-1.

[0182]

[0183] Comparative Examples 2, 4, and 5, and Examples 1 to 4 All components were mixed together at once and uniformly to prepare the first pack in the same manner as in Comparative Example 1, except that the components and their amounts in the first pack were changed to those shown in Table 2. The second pack used was the same as in Comparative Example 1.

[0184] Comparative Example 3 A first part was prepared by mixing all the components at once and uniformly in the same manner as in Comparative Example 1, except that the components and their amounts in the first part were changed to those shown in Table 2. As the second part, the second part of 2-2 containing no catalyst was used.

[0185] Example 5 A first agent was prepared by uniformly mixing all the components at once in the same manner as in Comparative Example 1, except that the components and their amounts in the first agent were changed to those shown in Table 2. A second agent 2-3 containing pigment-grade particles was used as the second agent.

[0186]

[0187] <Results> As is clear from a comparison of the results of Comparative Examples 4 and 5 and Examples 1 to 4 in Table 2, it was found that when the pigment-grade particles are contained in an amount of 0.01% by mass or more and less than 1.5% by mass, the effect of correcting recess defects and the natural finish performance are improved.

[0188] Furthermore, Example 5, which used a second agent containing pigment-grade particles, showed a more improved effect of correcting recessed defects than Example 1, which used a second agent containing no pigment-grade particles. This indicates that the effect of correcting recessed defects is improved when both the first and second agents contain pigment-grade particles.

[0189] Test Example 2 Test samples in this test example were prepared according to the following method. In this test example, the effect of film thickness was investigated. The results are shown in Table 3.

[0190] Example 6: Coating thickness: 50 μm A first part was prepared by mixing all of the components at once and uniformly mixing them in the same manner as in Comparative Example 1, except that the components and their amounts in the first part were changed to those shown in Table 3. For the second part, 2-1 in Table 1 was used.

[0191] Example 7 Coating Thickness: 100 μm A first part was prepared by mixing all of the components at once and uniformly mixing them in the same manner as in Comparative Example 1, except that the components and their amounts in the first part were changed to those shown in Table 3. For the second part, 2-1 in Table 1 was used.

[0192]

[0193] <Results> As is clear from the results in Table 3, it was found that the thicker the film, the more improved the effect of correcting recess defects.

[0194] <Evaluation Test 2> The following tests were carried out using the test samples obtained by the manufacturing methods described below, and the results are shown in Table 4.

[0195] <Evaluation of Appearance and Coating Color of Second-Part Agent (Evaluation of Powder Dispersibility)> The second-part agent was stirred for 10 minutes using a homomixer at 7,000 rpm, and the appearance color immediately thereafter was visually confirmed. Next, the first-part agent (approximately 3 g) was applied to a black board with a doctor blade to form a first-part agent layer, and the second-part agent (approximately 3 g) was applied to this first-part agent layer with a doctor blade, and the coating color of the resulting second-part agent layer was visually confirmed. If the appearance and coating colors were both substantially uniform and substantially consistent with each other, the test was evaluated as "passed," and if not, as "failed." Note that, since this test focused on the appearance and coating colors of the second-part agent, no catalyst was added to the second-part agent.

[0196] Reference Examples 1 to 6 and Reference Comparative Examples 1 to 11 First Agent A first agent was prepared by uniformly mixing 90 parts by mass of vinyl dimethicone as the first unsaturated organopolysiloxane and 10 parts by mass of hydrogen dimethicone as the first hydride-functionalized polysiloxane.

[0197] <Second Agent> The ingredients in Table 4 were mixed uniformly to prepare the second agents.

[0198]

[0199] <Results> The second agent of Reference Comparative Example 1, which did not contain a silicone surfactant, exhibited poor powder dispersibility, resulting in unevenness in both the appearance and application color. On the other hand, the second agents of Reference Examples 1 to 3, which contained a silicone surfactant, and the second agents of Reference Examples 4 to 6, which had higher powder ratios than the second agents, all exhibited excellent powder dispersibility and did not exhibit unevenness in both the appearance and application color, resulting in evaluation results at a pass level. Note that while Reference Examples 1 to 3 all achieved pass levels, it was confirmed that the performance was best in the following order: PEG / PPG-19 / 19 dimethicone, carboxydecyl trisiloxane, and bis-butyl dimethicone polyglyceryl-3, i.e., bis-butyl dimethicone polyglyceryl-3 was the best in terms of performance.

[0200] From the results of Reference Comparative Examples 2 to 6, it was also confirmed that no effect was obtained with surfactants and dispersants other than silicone surfactants.

[0201] Furthermore, from the results of Reference Comparative Examples 7 to 11, it was also confirmed that even if the proportion of powder was reduced, no effect could be obtained with surfactants and dispersants other than silicone-based surfactants.

[0202] <<Formulation Examples of Second Agents>> Formulation examples of second agents of the paint-on film-forming agent of the present disclosure are given below, but the present invention is not limited to these examples. The second agents described in the following formulation examples also exhibited excellent powder dispersibility and were free of color unevenness in both the appearance color and the applied color, resulting in evaluation results that met the pass level.
