Description

Technical Field

[0001] This disclosure relates to a coating film forming agent, a kit containing the forming agent, and a method of using the forming agent. Background Technology

[0002] Known substances include coating-type film-forming agents that are applied to the skin 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 containing one or more crosslinkable polymers for in-situ forming a layer on the surface of a subject's skin, and an artificial skin containing a layer formed from the composition.

[0004] Patent document 2 discloses a cosmetic material for pore correction, which contains 1) a gel structure made of cross-linked polydimethylsiloxane and cyclomethylsiloxane, 2) 1-10% by mass of water, 3) 15-40% by mass of silica, 4) 1-10% by mass of titanium dioxide-coated spherical powder, and 5) 0.5-5% by mass of sericite that can be coated with other metal oxides.

[0008] Patent Document 1: Japanese Patent Publication No. 2019-503396

[0009] Patent Document 2: Japanese Patent Application Publication No. 2009-155211

[0010] Patent Document 3: International Publication No. 2022 / 215531

[0012] Patent Document 5: International Publication No. 2022 / 124079 Summary of the Invention

[0013] The problem that the invention aims to solve

[0014] If the coating-type film-forming agent described in Patent Document 1 is applied to the skin and cross-linked, a film is formed on the skin surface in a concave, warped manner. Therefore, this forming agent typically reduces the concavity of wrinkles and other defects in the skin by stretching them, but sometimes it is insufficient to make the concavity defects less noticeable solely by stretching.

[0015] Conventional cosmetics for correcting pores, as described in Patent Document 2, are sometimes ineffective or produce unnatural results.

[0016] Therefore, it is desirable to develop a coating-type film-forming agent that has excellent corrective effect on concave defects such as pores and presents a natural makeup effect.

[0017] Therefore, according to one aspect of this disclosure, a coating-type film-forming agent can be provided that can form a film that has an excellent corrective effect on concave defects such as pores and presents a natural makeup effect.

[0018] In addition, if powders such as pigments are mixed with coating film forming agents or cosmetics containing unsaturated organopolysiloxanes such as vinyl polydimethylsiloxane, the dispersibility of the powders in the forming agent or cosmetic may sometimes decrease.

[0019] Therefore, according to another aspect of this disclosure, a coating-type film-forming agent or cosmetic containing unsaturated organopolysiloxane can be provided to improve the dispersibility of powder.

Figure 4 (Right) is a photograph of the coating color containing a silicone surfactant, powder, and unsaturated organopolysiloxane (Agent 2 in Table 5). Detailed Implementation

[0053] The embodiments of this disclosure are described in detail below. This disclosure is not limited to the following embodiments, and various modifications can be made within the scope of the spirit of the invention.

[0054] One aspect of this disclosure relates to a coating-type film-forming agent comprising a first agent and a second agent, wherein the first agent comprises a crosslinking reactive component constituting the film, and the second agent comprises a catalyst for crosslinking the crosslinking reactive component, and the first agent and / or the second agent comprises 0.01% by mass and less than 1.5% by mass of pigment-grade particles having a refractive index of 2.0 or higher.

[0055] While not limited by the principle, it can be considered that the coating-type film-forming agent of this disclosure can form a film that has an excellent corrective effect on pores and other concave defects and presents a natural makeup effect. The working principle is as follows.

[0056] It can be considered as follows Figure 1 As shown in (a), in a concave defect like a pore, the light incident on it (arrow in the figure) is deflected by the wall of the concave part, thus creating a shadow, making the defect more noticeable.

[0057] For example, traditional pore-minimizing cosmetics contain a large amount of pigment, thus concealing pores through application. Therefore, while this can make pores less noticeable, it can sometimes create an unnatural makeup effect. Additionally, cosmetics with less pigment sometimes have lower viscosity. In this case, it can be considered that... Figure 1As shown in (b), it is difficult to apply a thick layer, resulting in insufficient filling of the recesses, and therefore... Figure 1 The same effect as (a) creates a shadow, and its defects are obvious. In addition, even when thickeners are used to increase the viscosity of cosmetics with less pigment, conventional cosmetics sometimes result in makeup that comes off after application, creating an unnatural makeup effect.

[0058] Regarding a coating-type film-forming agent according to one aspect of this disclosure, at least one of the first and second agents constituting the forming agent contains 0.01% by mass and less than 1.5% by mass of pigment-grade particles having a refractive index of 2.0 or higher. The inventors have discovered that coating-type film-forming agents containing such high-refractive-index pigment-grade particles, compared to general cosmetics, such as... Figure 1 As shown in (c), a thick application can be used to fill in pores and other concave defects, thus achieving excellent correction of these defects even with a small amount of pigment particles mixed in. This effect can be attributed to the high refractive index pigment particles being configured to substantially reflect light orthogonally within the film filling the concave areas. Furthermore, the small amount of pigment particles in the film, coupled with cross-linking when applied to the skin, makes it less prone to fading like conventional cosmetics, resulting in a natural makeup finish. It should be noted that... Figure 1 In the simulation results of (b) and (c), the concave defects (pores) are whitened to make the location and shadow of the concave defects easier to see. In actual films, if coloring materials are used to adjust the color of the film, the white part may not be obvious.

[0059] Furthermore, when ordinary cosmetics are applied to the skin, the pigment particles are affected by factors such as body temperature and flow. As a result, they are not fixed in the layer formed by the cosmetic and may migrate over time, moving deeper into areas such as isotropic depressions. Therefore, even if a cosmetic contains high-refractive-index pigment particles at a low concentration and can be applied thickly, it can be considered that such a cosmetic cannot adequately demonstrate the effect of correcting depressions and achieving a natural makeup look.

[0060] On the other hand, the film made by the coating-type film-forming agent according to one aspect of this disclosure is a film with a cross-linked structure formed by a first agent containing a cross-linking reactive component constituting the film and a second agent containing a catalyst for cross-linking the cross-linking reactive component. As a result, the pigment-level particles contained in the film are immobilized in a uniformly dispersed state within the film, and therefore, compared with conventional cosmetics as described above, it is considered suitable for expressing the correction effect of depressions and defects and the performance of a natural makeup effect.

[0061] It should be noted that, for example, conventional cosmetics with pore-minimizing capabilities still suffer from the problem of peeling off when applied to the skin due to sweat or friction. The coating-type film-forming agent of this disclosure allows the formulation to be applied to the skin and cross-linked to form a film. Therefore, the resulting cross-linked film exhibits superior resistance to peeling caused by friction compared to films obtained by applying conventional cosmetics to the skin. Therefore, it can be considered that the coating-type film-forming agent according to one aspect of this disclosure can also contribute to addressing the peeling problem inherent in conventional cosmetics.

[0062] Furthermore, conventional cosmetics require the use of cleansing agents to remove them from the skin. On the other hand, the film formed by the coating-type film-forming agent according to the present disclosure has a cross-linked structure, resulting in superior film strength compared to films without a cross-linked structure. Consequently, unlike films formed by conventional cosmetics, it also has the advantage of being easily peelable from the skin.

[0063] The terms used in this disclosure are defined as follows.

[0064] In this disclosure, "viscosity" refers to a measure of the resistance of a fluid to deformation under either shear or tensile stress. For example, the viscosity of the first and second agents in a coating-type film-forming agent affects the thickness, ductility, and uniformity and / or consistency of the layer formed on a substrate. Viscosity can be expressed as dynamic viscosity (also known as absolute viscosity, typically measured in Pa). s, poise, p, cP.) or kinematic viscosity (representative unit is cm⁻²). 2 The kinematic viscosity is reported by any of the following: (s, Stokes, St, cst). It is obtained by dividing the dynamic viscosity by the density of the fluid being measured. The viscosity ranges of the components disclosed in this specification are generally provided by the suppliers of the components as units of kinematic viscosity (e.g., cst) measured using a rheometer or a Cannon-Fenske tube viscometer. However, the viscosity of the fluid may also be measured, for example, using a rheometer (e.g., a linear shear rheometer or a dynamic shear rheometer) or a viscometer (also known as a viscometer, e.g., a capillary viscometer or a rotational viscometer).

[0065] In this disclosure, "crosslinking" generally also includes the concept of "curing".

[0066] In this disclosure, the term "object part" refers to the part on which the correction of the concave defect is desired.

[0067] In this disclosure, "correction of depression defects" means that, compared to before the application of the film formed by the coating-type film-forming agent of this disclosure, depression defects in the skin become less noticeable or are concealed after the application of the film. In this disclosure, "depression defects" refers to concave areas of the body (e.g., pores, skin grooves, wrinkles, wounds, etc.). Here, "concave areas of the body" can refer to, for example, concave parts of the body that the subject is concerned about, or concave parts of the body that the subject wants to correct, or concave parts of the subject's body that a person skilled in the art, such as a dermatologist, beautician, or plastic surgeon, deems best to correct. 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 are no particular restrictions on the upper limit of this maximum depth; it can be set to, for example, less than 2 mm, less than 1.5 mm, less than 1 mm, less than 800 μm, less than 500 μm, or less than 300 μm.

[0068] In this disclosure, "pigment grade" refers to particles of a size capable of functioning as pigments. Pigment grade particles and other particles can be distinguished, for example, by their size. For instance, the size of pigment grade particles can be defined using the average particle size calculated by static light scattering. This 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; or it 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 with the same type of titanium dioxide particles, titanium dioxide particles with an average particle size of 300 nm can be treated as pigment grade particles, while titanium dioxide particles with an average particle size of 80 nm can be treated as ultraviolet scattering particles, etc.

[0069] Coating-type film-forming agents

[0070] In one embodiment of this disclosure, a coating-type film-forming agent (sometimes simply referred to as a "forming agent") comprises, for example, a first agent and a second agent, wherein the first agent contains a crosslinking reactive component constituting a film, and the second agent contains a catalyst for crosslinking the crosslinking reactive component. At least one of the first and second agents contains 0.01% by mass and less than 1.5% by mass of pigment-grade particles having a refractive index of 2.0 or higher. According to one embodiment of this disclosure, the coating-type film-forming agent is suitable for use on pitted defects in the skin due to its excellent corrective effect on pitted defects such as pores, and is particularly suitable for pore correction.

[0071] In several embodiments, the coating performance of the coating-type film-forming agent can be evaluated using the viscosity obtained using a Type B viscometer (manufactured by Shibaura System Co., Ltd., Vismetron). The viscosity of the first and second agents in the coating-type film-forming agent according to one embodiment of this disclosure, measured at 25°C and 60 rpm (rotor No. 3 or No. 4), immediately after preparation, can be set, for example, to be 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, Above 000 mPa·s can be set to below 1,000,000 mPa·s, below 750,000 mPa·s, below 500,000 mPa·s, below 250,000 mPa·s, below 200,000 mPa·s, below 175,000 mPa·s, below 150,000 mPa·s, below 125,000 mPa·s, below 100,000 mPa·s, or below 80,000 mPa·s. From the viewpoint of smooth coating performance and suppression of dripping from the target area, the first and second agents of the coating-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 coating (i.e., obtaining a film with a thickness of, for example, 50 μm or more), at least one of the first and second agents in the coating-type film-forming agent, preferably the first agent, 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. There is no particular restriction on the upper limit of viscosity at this point; it can be set, for example, below 100,000 mPa·s, below 80,000 mPa·s, below 50,000 mPa·s, or below 30,000 mPa·s.

[0072] In several embodiments, regarding the viscosity of the first and second agents in the coating-type film-forming agent according to one embodiment of this disclosure after 2 weeks, measured at 25°C and 60 rpm (rotor No. 3), from the viewpoint of smooth coating performance and suppression of dripping from the target area, it is preferably 50,000 mPa·s or less, 30,000 mPa·s or less, or 15,000 mPa·s or less, and preferably 5,000 mPa·s or more, 7,000 mPa·s or more, or 10,000 mPa·s or more.

[0073] In another embodiment, the coating-type film-forming agent (sometimes simply referred to as "forming agent") comprises, for example, a powder as described later. In this embodiment, the powder may be contained in the first agent, in the second agent, or in both the first and second agents. The powder may contain pigment-grade particles (sometimes simply referred to as "pigment-grade particles") having a refractive index of 2.0 or higher. The powder may contain particles different from the pigment-grade particles described above.

[0074] Furthermore, in this embodiment, the coating-type film-forming agent may contain an unsaturated organopolysiloxane. When the unsaturated organopolysiloxane and the powder are contained in the same system (e.g., agent 1 or agent 2), the system containing the unsaturated organopolysiloxane and the powder may further contain an organosilicon surfactant. This improves the dispersibility of the powder.

[0075] <Dose 1>

[0076] In one embodiment of this disclosure, the coating-type film-forming agent contains a first agent comprising a crosslinking reactive component constituting the film.

[0077] As described above, in one embodiment, the first agent may contain pigment-grade particles (sometimes simply referred to as "pigment-grade particles") having a refractive index of 2.0 or higher. The first agent contains cross-linking reactive components that constitute the film, enabling the formation of the final film. Therefore, if the first agent contains these pigment-grade particles, the correction effect of depression defects and the natural makeup effect can be further improved.

[0078] (Pigment-grade particles with a refractive index of 2.0 or higher)

[0079] From the viewpoint of correcting concave defects and achieving a natural makeup effect, the refractive index of the pigment-grade particles is preferably 2.0 or higher, 2.1 or higher, 2.2 or higher, 2.3 or higher, or 2.4 or higher; and preferably 3.0 or lower, 2.9 or lower, or 2.8 or lower. Here, the refractive index of the pigment-grade particles can be determined, for example, according to JIS K0062:1992.

[0080] When the first agent contains the pigment-grade particles, from the viewpoint of correcting depression defects and achieving a natural makeup effect, the mixing amount relative to the total amount of the first agent is preferably 0.01% by mass or more or 0.02% by mass, more preferably 0.03% by mass or more, 0.04% by mass or more or 0.05% by mass, and preferably less than 1.5% by mass, less than 1.3% by mass, less than 1.0% by mass, less than 0.8% by mass, less than 0.5% by mass, less than 0.3% by mass, less than 0.1% by mass, less than 0.09% by mass, less than 0.08% by mass, or less than 0.07% by mass.

[0081] There are no particular limitations on pigment-grade particles as long as they have a refractive index of 2.0 or higher. Examples of pigment-grade particles include, for instance, at least one selected from 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 viewpoint of correcting depressions and achieving a natural makeup effect. Pigment-grade particles can be used alone or in combination of two or more types.

[0082] Here, the term "pearlescent pigment" in this disclosure refers to particles that exhibit a luminous quality. Pearlescent pigments typically exhibit a flat, plate-like form, such as flakes or scales. Examples of pearlescent pigments include, for instance, mica titanium. Titanium), iron oxide-coated mica titanium, carmine-coated mica titanium, carmine-Prussian blue-coated mica titanium, iron oxide-carmine-treated mica titanium, Prussian blue-treated mica titanium, iron oxide-Prussian blue-treated mica titanium, chromium oxide-treated mica titanium, black titanium oxide-treated mica titanium, 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 red titanium oxide-coated mica coated with iron oxide and titanium oxide, etc., iron oxide titanium oxide-coated mica, hollow titanium oxide powder with silica sandwiched between mica and titanium oxide coating layers.

[0083] Colorless pearlescent pigments can also be used as pearlescent pigments. As such, known substances as transparent pearlescent pigments (transparent glossy pigments) can be used. For example, a pearlescent pigment in which a film of a high-refractive-index material such as titanium oxide is formed on the surface of glass particles as a substrate can be used.

[0084] Pigment particles can be hydrophobically treated. Hydrophobically treated pigment particles (hydrophobic pigment particles) can be easily and evenly dispersed in the film, thus further improving the correction effect of depressions and the natural makeup effect.

[0085] There are no particular limitations on the hydrophobication treatment of pigment-grade particles. Any treatment that modifies the surface of the particles with organic compounds to achieve hydrophobicity can be cited. Examples include organosilicon-based or silane-based treatments using methylhydropolysiloxane, dimethylpolysiloxane (polydimethylsiloxane), alkylsilanes, etc.; fluorine-based treatments using perfluoroalkyl phosphates, perfluoroalcohols, etc.; titanate-based treatments using alkyl titanates, etc.; amino acid treatments using N-acylglutamic acid, etc. Other examples include lecithin treatment; metal soap treatment; fatty acid treatment; and alkyl phosphate ester treatment. Multiple hydrophobication treatments can be used alone or in combination. Furthermore, hydrophobication treatments can be carried out using hydrophobicating agents.

[0086] Examples of organosilicones used as hydrophobic treatment agents include, for instance, known organosilicones having hydrogen-silicon bonds, such as methylhydropolysiloxane (polydimethylsiloxane / polymethylsiloxane) copolymers. Other examples include triethoxysilylethyl polydimethylsiloxane and triethoxysilylethyl polydimethylsiloxane, which have alkoxy-silicon bonds as reactive groups. Dimethylpolysiloxanes can also be used.

[0087] Examples of silane-based processing agents include, for example, silylating agents that incorporate organic groups, and silane coupling agents, such as triethoxyoctylsilane.

[0088] Examples of titanium coupling agents that can be used as titanate-based treatment agents include alkyl titanates, pyrophosphate-type titanates, phosphorous acid-type titanates, and amino acid-type titanates.

[0089] In several embodiments, the first agent of this disclosure comprises at least one selected from a first unsaturated organopolysiloxane and a first hydrogen-functionalized polysiloxane as the crosslinking reactive component. From the viewpoint of obtaining a good film, if the first agent comprises only the first unsaturated organopolysiloxane and the first hydrogen-functionalized polysiloxane, the second agent in the forming agent of this disclosure preferably comprises a second hydrogen-functionalized polysiloxane. Furthermore, if the first agent comprises only the first hydrogen-functionalized polysiloxane and the first hydrogen-functionalized polysiloxane, the second agent preferably comprises a second unsaturated organopolysiloxane. From the viewpoint of obtaining a better film, it is preferable that the first agent comprises both the first unsaturated organopolysiloxane and the first hydrogen-functionalized polysiloxane.

[0090] The dosage form of the first agent is not particularly limited and can be, for example, a single-phase system consisting of an oil phase, a two-phase system consisting of a non-emulsified oil-in-water or water-in-oil emulsion, or a two-phase system consisting of an oil-in-water emulsion or a water-in-oil emulsion. Here, a single-phase system consisting of an oil phase typically refers to an anhydrous form. In this disclosure, "anhydrous" means not only that the composition does not contain water, but also that the water content is small, 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 can include a water-in-oil composition in which water droplets are forcibly dispersed in a dispersion medium containing oil by oscillating a liquid separated into water and oil states, or an oil-in-water composition in which oil droplets are forcibly dispersed in a dispersion medium containing water.

[0091] These dosage forms can be appropriately formulated using conventional methods with cross-linking reactive components and, optionally, known materials such as oils, emulsifiers, and water, as described later.

[0092] Since the first agent is applied to the target area (e.g., the face) by coating or the like, it is preferable to have a glass transition temperature below body temperature from the viewpoint of coating performance. For example, the glass transition temperature can be set to below 37°C, below 25°C, below 10°C, or below 0°C. There is no particular limitation on the lower limit of the glass transition temperature, and it can be set to, for example, above -30°C, above -20°C, or above -10°C.

[0125] <Second dose>

[0126] The second agent constituting the coating-type film-forming agent of this disclosure includes a catalyst that crosslinks the crosslinking reactive component in the first agent. The second agent of this disclosure can contain pigment-grade particles having a refractive index of 2.0 or higher, similar to the first agent. If both the first and second agents contain these pigment-grade particles in an amount ranging from 0.01% to less than 1.5% by mass, the pigment-grade particles are easily disposed near the surface of the film, and light incident on the film is more easily reflected near the surface, thus further improving the correction effect of recessed defects. Furthermore, if the second agent further includes an unsaturated organopolysiloxane (a second unsaturated organopolysiloxane), the pigment-grade particles are more easily disposed near the surface of the film and easily immobilized near the surface, thus further improving the correction effect of recessed defects.

[0127] (catalyst)

[0128] There are no particular limitations on the catalyst; examples include any substance capable of initiating, promoting, or triggering physical and / or chemical cross-linking reactions in unsaturated organopolysiloxanes and hydrogen-functionalized polysiloxanes that are cross-linking reactive components constituting the film. The catalyst may or may not undergo permanent physical and / or chemical changes during or at the end of the process.

[0129] The catalyst is not limited to the following substances, but includes metal catalysts capable of initiating and / or promoting cross-linking below body temperature, such as Group VIII metal catalysts including platinum, rhodium, palladium, cobalt, nickel, ruthenium, osmium, and iridium catalysts, and Group IVA metal catalysts including germanium and tin catalysts.

[0133] Among these catalysts, platinum catalysts are preferred, and platinum-divinyltetramethyldisiloxane coordination compounds (sometimes also referred to as "platinum-divinyldisiloxane") are particularly preferred.

[0134] Regarding the amount of catalyst mixed in the second agent, there are no particular restrictions as long as it can be adjusted appropriately according to the required film performance, etc. For example, the amount of catalyst mixed relative to the total amount of the second agent can be set to 0.001% by mass or more, 0.005% by mass or more, or 0.010% by mass or more, or it can be set to less than 5.0% by mass, less than 3.0% by mass, less than 1.0% by mass, less than 0.10% by mass, or less than 0.050% by mass. The catalyst can be used appropriately within such ranges.

[0135] The dosage form of the second agent disclosed herein is not particularly limited. For example, it may be a single-phase system consisting of an oil phase in an anhydrous form, a two-phase system consisting of a non-emulsified oil-in-water or water-in-oil emulsion, or a two-phase system consisting of an oil-in-water emulsion or a water-in-oil emulsion.

[0136] These formulations can be appropriately prepared using conventional methods with known materials such as catalysts and, optionally, oils, emulsifiers, and water, as described later. It should be noted that silicone oil can be used as the oil, and the first unsaturated organopolysiloxane and the first hydrogen-functionalized polysiloxane that can be used in the first agent described above can also be used as this silicone oil. In this case, to distinguish them from the first unsaturated organopolysiloxane and the first hydrogen-functionalized polysiloxane in the first agent, the unsaturated organopolysiloxane and the hydrogen-functionalized polysiloxane in the second agent can be referred to as the second unsaturated organopolysiloxane and the second hydrogen-functionalized polysiloxane.

[0139] The coating-type film-forming agent of this disclosure can be appropriately mixed with various components of Agent 1 and / or Agent 2 to a extent that it does not adversely affect the effects of this disclosure. Optional components can be used alone or in combination of two or more.

[0142] Here, we will describe in detail some of the main materials among the optional components.

[0143] (Inorganic particles)

[0144] In several embodiments, at least one of the first and second agents of the coating-type film-forming agent of this disclosure, preferably the first agent, comprises inorganic particles other than the pigment-grade particles described above, such as hydrophobic inorganic oxide particles (hydrophobic inorganic oxide particles). The use of hydrophobic inorganic oxide particles can contribute to thick coating by increasing the viscosity of the coating-type film-forming agent, and also contributes to improving the strength of the film.

[0145] From the viewpoint of achieving thicker film thickness and good film strength, the average particle size 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 are no particular limitations on the lower limit of the average particle size; for example, it can be set to 1 nm or more, 3 nm or more, or 5 nm or more. Here, the average particle size can refer, for example, to the particle size converted to the case of spherical particles having the same area as the projected area of ​​the particle observed by a transmission electron microscope (area equivalent circular particle size). The area equivalent circular particle size can be defined as the average value of 10 or more particles.

[0146] Examples of inorganic oxides constituting hydrophobic inorganic oxide particles include zinc oxides, titanium oxides, aluminum oxides, and silicon oxides (e.g., fumed silica and anhydrous silica). Preferably, at least one of silicon oxides, titanium oxides, and zinc oxides is selected, and silicon oxide is more preferred.

[0147] Hydrophobic inorganic oxide particles can typically be inorganic oxide particles that have undergone hydrophobic treatment with a surface treatment agent. There are no particular limitations on the hydrophobic treatment; for example, from the viewpoint of thickening the film and obtaining good film strength, at least one of dimethyl silylation treatment and trimethyl silylation treatment is preferred.

[0148] The amount of inorganic particles (e.g., hydrophobic inorganic oxide particles) mixed with respect to the total amount of the first or second agent can be, for example, set to 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 set to 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. Inorganic particles (e.g., hydrophobic inorganic oxide particles) can be appropriately used within such ranges.

[0149] (oil content)

[0150] Examples of oils include liquid greases, solid greases, waxes, hydrocarbon oils, ester oils, silicone oils, and polar oils. Oils can be non-volatile or volatile. Oils can be used alone or in combination of two or more. Here, "volatility" refers to a substance that, after being placed at atmospheric pressure and 105°C for 3 hours, exhibits a volatile fraction exceeding 5%. This volatile fraction can be specified 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 can be set to below 250°C, below 240°C, or below 230°C; alternatively, it can be set to above 80°C, above 100°C, above 120°C, above 150°C, or above 160°C. Furthermore, the term "non-volatile" in this disclosure refers to a substance that has less than 5% volatile content when placed at 105°C for 3 hours.

[0151] For example, silicone oils other than the aforementioned unsaturated organopolysiloxanes and hydrogen-functionalized polysiloxanes can be used. Such silicone oils may include, for example, chain polysiloxanes such as dimethylpolysiloxane (polydimethylsiloxane), methylphenylpolysiloxane, and methylhydropolysiloxane; and cyclic polysiloxanes such as diphenylsiloxyphenylpolytrimethylsiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecylcyclohexasiloxane. Because silicone oils are readily compatible with unsaturated organopolysiloxanes containing phenyl and vinyl groups, they are suitable for mixing with first and / or second agents containing unsaturated organopolysiloxanes containing phenyl and vinyl groups.

[0152] There are no particular restrictions on the mixing amount of the oil (e.g., silicone oil). For example, it can be appropriately mixed depending on the type of formulation used, the required film strength, etc. The mixing amount of the oil (e.g., silicone oil), relative to the total amount of the first or second agent, can be set to 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 less. It can also be set to less than 60% by mass, less than 57% by mass, less than 55% by mass, less than 50% by mass, less than 45% by mass, less than 40% by mass, less than 35% by mass, less than 30% by mass, less than 25% by mass, or less than 20% by mass. The oil can be used appropriately within these ranges.

[0153] (Emulsifier)

[0154] As emulsifiers, for example, anionic, cationic, amphoteric, or nonionic emulsifiers can be used. Emulsifiers can be used alone or in combination of two or more. Here, the term "emulsifier" in this disclosure refers to a formulation having emulsifying function (surface activity), and may also include formulations generally referred to as surfactants.

[0155] Specifically, examples of emulsifiers include at least one selected from hydrocarbon surfactants, organosilicon surfactants, and amphiphilic powders.

[0156] Examples of hydrocarbon-based surfactants include, for example, polyoxyethylene alkyl ethers, polyoxyethylene sterol ethers, polyoxyethylene fatty acid esters, polyoxyethylene polyol fatty acid esters, polyoxyethylene hydrogenated castor oil, polyoxyethylene dehydrated sorbitol fatty acid esters, diol fatty acid esters, glycerol fatty acid esters, dehydrated sorbitol fatty acid esters, sucrose fatty acid esters, and polyglycerol fatty acid esters.

[0157] Examples of organosilicon surfactants include, for example, polyether-modified organosilicon and alkyl co-modified polyether-modified organosilicon.

[0158] There are no particular restrictions on the amount of emulsifier mixed in the formula. For example, from the viewpoint of emulsion stability, it can be set to 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 are no particular restrictions on the upper limit of the amount of emulsifier mixed in the formula. For example, it can be set to 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. Emulsifiers can be used appropriately within these ranges.

[0159] (Organosilicon surfactants)

[0160] As described above, the coating-type film-forming agent may comprise a powder. Furthermore, the powder may comprise pigment-grade particles having a refractive index of 2.0 or higher, or it may substantially not contain such pigment-grade particles. When the powder comprises the pigment-grade particles, the mass ratio of these pigment-grade particles to the mass of the coating-type film-forming agent may be set to 0.01% by mass or more and less than 1.5% by mass.

[0161] In several embodiments, when the powder is mixed with an unsaturated organopolysiloxane in the coating film forming agent of this disclosure, the dispersibility of the powder can be improved by further mixing an organosilicon surfactant into the system containing them. It should be noted that, in the view that the dispersibility of the powder is improved by further including an organosilicon surfactant in the mixture of unsaturated organopolysiloxane and powder, the mass ratio of pigment particles to the mass of the coating film forming agent can be less than 0.01% by mass or more than 1.5% by mass.

[0162] When considering the dispersibility of powder, a dispersant that acts on the powder is generally chosen (e.g., a dispersant that exhibits a steric hindrance effect on the powder surface). On the other hand, it can be considered that the organosilicon surfactant used in the forming agent of this disclosure is different from such a general dispersant, as it does not act on the powder, but rather on the unsaturated organopolysiloxane.

[0163] For example, such as Figure 2 As shown in (a), when powder and unsaturated organopolysiloxane are mixed in the oil phase, the powder's dispersibility is likely to decrease because the unsaturated organopolysiloxane acts to cause powder agglomeration. Therefore, it is considered that even when a general dispersant that acts on the powder is mixed into such a system, it is not easy to obtain a sufficient dispersion effect.

[0164] On the other hand, the organosilicon surfactants mixed in the forming agent of this disclosure have excellent affinity with unsaturated organopolysiloxanes that can act as agglomerating agents for powders, therefore it can be considered that... Figure 2 As shown in (b), the hydrophobic group of the organosilicon surfactant interacts with the unsaturated organopolysiloxane and is dispersed in the oil phase in a reverse micelle configuration. As a result, the powder agglomeration effect of the unsaturated organopolysiloxane is considered reduced, thus improving the dispersibility of the powder in the forming agent. Here, Figure 2 In (b), the black rods of the organosilicon surfactants represent hydrophobic groups, and the white spheres represent hydrophilic groups.

[0165] In several embodiments, the amount of the silicone-based surfactant in the first or second agent of the powder-forming agent may, for example, be 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, or may be 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. The silicone-based surfactant can be appropriately used within such ranges.

[0166] In several embodiments, the amount of the silicone surfactant in the first or second agent of the powder-forming agent may also be specified as a ratio relative to 100 parts by mass of the powder, the unsaturated organopolysiloxane, and the silicone surfactant. In this case, the amount of the silicone surfactant relative to 100 parts by mass of the powder, the unsaturated organopolysiloxane, and the silicone surfactant may 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; and may 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.

[0167] Organosilicon surfactants can be used alone or in combination of two or more.

[0168] As a silicone-based surfactant, for example, from the viewpoint of improving powder dispersibility, a silicone-based surfactant having an HLB value of 10.0 or less is preferred. This HLB value can be set to 9.0 or less, 8.0 or less, 7.0 or less, 6.0 or less, or 5.0 or less. There are no particular limitations on the lower limit of the HLB value; for example, it can be set to 0.1 or more, 0.5 or more, 1.0 or more, 1.5 or more, or 2.0 or more. Among these, from the viewpoint of improving powder dispersibility, an HLB value of 0.1 or more and 7.0 or less is preferred. Here, "HLB" generally refers to the value of affinity for water and oil, and is a parameter known as the hydrophilic-lipophilic balance. The HLB value of a silicone-based surfactant can be easily determined using the Griffin method. Here, the HLB value based on the Griffin method can be determined using the following formula a: HLB value = 20 × total formula weight of hydrophilic portion / molecular weight ... Formula a Specific examples of organosilicon surfactants that can improve the dispersibility of powders include, for example, polyglycerol-alkyl co-modified organosilicon, carboxyl-modified organosilicon, and polyether-modified organosilicon.

[0169] (Polyglycerol-alkyl co-modified organosilicon)

[0170] Examples of polyglycerol-alkyl co-modified organosilicones include, for instance, bisbutyl polydimethylsiloxane polyglycerol-3 and cetyl PEG / PPG-10 / 1 polydimethylsiloxane. Here, "PEG" and "PPG" refer to polyethylene glycol and polypropylene glycol, respectively.

[0171] (Carboxyl-modified organosilicon)

[0172] Examples of carboxyl-modified organosilicones include carboxydecyltrisiloxane.

[0173] (Polyether-modified organosilicon)

[0174] Examples of polyether-modified organosilicones include, for example, PEG-9 polydimethylsiloxyethyl polydimethylsiloxane, PEG-10 polydimethylsiloxane, PO / EO modified organosilicones (e.g., PEG / PPG-19 / 19 polydimethylsiloxane), and polydimethylsiloxane / (PEG-10 / 15) crosspolymers. Here, "PO" and "EO" refer to propylene oxide and ethylene oxide, respectively.

[0175] <Powder>

[0176] In several embodiments, the coating-type film-forming agent or cosmetic of this disclosure comprises a powder. The powder may be used alone or in combination of two or more powders.

[0177] In several embodiments, the amount of powder mixed varies and can be appropriately set according to the intended use of the cosmetic. For example, the amount of powder mixed, relative to the total amount of the coating film-forming agent (e.g., agent 1 or agent 2) or the cosmetic, can be set to 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. Alternatively, it can be set to 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 mixed can be appropriately incorporated into the coating film-forming agent or cosmetic within such a range.

[0178] In several embodiments, the amount of powder mixed in the coating film-forming agent (e.g., agent 1 or agent 2) or cosmetic may also be specified as a ratio relative to 100 parts by mass of the powder, unsaturated organopolysiloxane, and organosilicon surfactant. In this case, the amount of powder mixed relative to 100 parts by mass of the powder, unsaturated organopolysiloxane, and organosilicon surfactant may 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; alternatively, it may 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.

[0179] In several embodiments, there are no particular limitations on the powder used; for example, spherical or non-spherical powders commonly used in the cosmetics field can be used. In coating-type film-forming agents (e.g., agent 1 or agent 2) or cosmetics, the powder may contain only spherical powder or non-spherical powder, or both.

[0180] In several embodiments, the coating-type film-forming agent or cosmetic of this disclosure comprises 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 also be 50 μm or less, 30 μm or less, 20 μm or less, 15 μm or less, or 10 μm or less. Regarding the spherical powder, powders with such an average particle size range can be used alone or in combination of two or more.

[0181] When the powder shape is assumed to be spherical, the average particle size can be defined as the average value of the diameter of the powder (particles) optically measured by dynamic light scattering.

[0182] In several embodiments, the coating-type film-forming agent or cosmetic of this disclosure comprises non-spherical powder. Non-spherical powder refers to powder that is not contained in the aforementioned spherical powder, and can be specified, for example, by its aspect ratio. The aspect ratio of the non-spherical powder can be set to 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 also be set to 200 or less, 170 or less, 150 or less, 120 or less, 100 or less, 70 or less, or 50 or less. Regarding the non-spherical powder, powders with aspect ratios in such ranges can be used alone or in combination of two or more.

[0183] The aspect ratio can be calculated, for example, by observing under a microscope and taking any number of powder samples (e.g., 100). The length of each powder sample along its long side (surface direction) and its short side (thickness direction) is measured, and the aspect ratio is calculated by dividing the length of the long side by the length of the short side (i.e., length of the long side / length of the short side). The longest long side is selected, and the shortest short side is selected. The aspect ratio can be set as the average of the aspect ratios of any number of powder samples (e.g., 100).

[0184] In several embodiments, there are no particular limitations on the type of powder used; for example, inorganic powders and / or organic powders can be used. Inorganic powders and organic powders can be used alone or in combination of two or more.

[0185] Examples of components constituting inorganic powders include, for example, talc, kaolin, mica (e.g., sericite, muscovite, phlogopite, synthetic mica, synthetic phlogopite iron, red mica, biotite), calcined talc, calcined mica (e.g., calcined sericite, calcined muscovite, calcined phlogopite), vermiculite, magnesium carbonate, calcium carbonate, aluminum silicate, barium silicate, calcium silicate, magnesium silicate, strontium silicate, borosilicate Ca / Al, tungstate metal salts, magnesium, silicon dioxide, aluminum oxide, zeolite, aluminum hydroxide, barium sulfate, calcined calcium sulfate (calcined gypsum), calcium phosphate, fluorapatite, hydroxyapatite, ceramic powder, metal soaps (e.g., zinc myristate, calcium palmitate, aluminum stearate, etc.), boron nitride, photochromic titanium oxide (titanium dioxide sintered with iron oxide), and reduced zinc oxide. Such powders are sometimes blended as pigments other than coloring pigments for the purpose of increasing or strengthening coating-type film-forming agents or cosmetics. Powders used for such purposes are sometimes referred to as extender pigments.

[0186] In addition, inorganic pigments (sometimes referred to as "inorganic coloring pigments") can also be used as inorganic powders. Examples of inorganic pigments include, for example, inorganic white pigments (e.g., titanium dioxide, zinc oxide); inorganic red pigments (e.g., iron oxide (iron oxide red), iron titanate); inorganic brown pigments (e.g., γ-iron oxide); inorganic yellow pigments (e.g., iron oxide yellow, loess); inorganic black pigments (e.g., iron oxide black, low-valent titanium oxide); inorganic purple pigments (e.g., manganese violet, cobalt violet); inorganic green pigments (e.g., chromium oxide, chromium hydroxide, cobalt titanate); and inorganic blue pigments (e.g., ultramarine, Prussian blue). Furthermore, glossy powders can also be used. Examples of such luminescent powders include, for example, pearlescent pigments (e.g., bismuth oxychloride, fish scale foil, mica titanium, iron oxide-coated mica titanium, low-valent titanium oxide-coated mica titanium, photochromic mica titanium, substances that use talc, glass, synthetic fluorophlogopite, silica, bismuth oxychloride, etc. as substrates instead of mica, substances coated with titanium oxide as coatings, and substances coated with low-valent titanium oxide, colored titanium oxide, iron oxide, alumina, silica, zirconium oxide, zinc oxide, cobalt oxide, aluminum, etc. as coatings, substances that are functional pearlescent pigments with resin particles coated on the surface of the pearlescent pigment, substances with aluminum hydroxide particles coated on the surface of the pearlescent pigment, substances with zinc oxide particles coated on the surface of the pearlescent pigment, and substances with barium sulfate particles coated on the surface of the pearlescent pigment); and metallic powder pigments (e.g., aluminum powder, copper powder).

[0187] Examples of components constituting organic powders include, for example, silicone elastomers, silicone, silicone resin-coated silicone elastomers, polyamide resins (e.g., nylon), polyolefin resins (e.g., polyethylene), polymethyl methacrylate, polystyrene, copolymers of styrene and acrylic acid, benzoguanamine resins, fluoropolymers (e.g., polytetrafluoroethylene), starch (e.g., octenyl succinate starch A1), (HDI / trimethylolhexyl lactone) crosslinking polymers, (diphenyl polydimethylsiloxane / vinyl diphenyl polydimethylsiloxane / sesquioxane) crosslinking polymers, and (IPDI / poly(1,4-butanediol)-14) crosslinking polymers, as well as cellulose.

[0188] In addition, organic pigments (sometimes also called "organic coloring pigments") and / or dyes can also be used as organic powders. Examples of organic pigments include, for example, zirconium, barium, or aluminum lake pigments. Specifically, examples include, for example, organic pigments such as Red 201, Red 202, Red 204, Red 205, Red 220, Red 226, Red 228, Red 405, Orange 203, Orange 204, Yellow 205, Yellow 401, and Blue 404, as well as Red 3, Red 104, Red 106, Red 227, Red 230, Red 401, Red 505, Orange 205, Yellow 4, Yellow 5, Yellow 202, Yellow 203, Green 3, and Blue 1.

[0189] Examples of pigments include natural pigments, such as chlorophyll and beta-carotene.

[0190] In several embodiments, the coating-type film-forming agent or cosmetic of this disclosure comprises a hydrophobic powder. The hydrophobic powder is suitable when dispersing the powder in an oil phase. Two or more hydrophobic powders can be used alone or in combination.

[0191] In this disclosure, "hydrophobicity" refers to the property of low affinity for water. Hydrophobicity can be evaluated, for example, by visually observing 50g of ion-exchanged water and 0.1g of evaluation powder placed in a transparent, sealed container and stored at 50°C for one day. Specifically, if most of the evaluation powder (e.g., more than 50% of the evaluation powder) is present near the surface of the ion-exchanged water (e.g., in an area approximately 1cm below the water surface), the powder can be evaluated as "hydrophobic." Furthermore, when the powder to be evaluated has a high specific gravity (e.g., exceeding 3.0 g / cm³), the hydrophobicity can also be assessed. 3 Or 5.0 g / cm 3In the above situations, the following method can be used instead of the above evaluation method to evaluate "hydrophobicity". For example, when ion-exchanged water is added to a container filled with powder at 25°C, the condition in which the water forms droplets that roll on the surface is evaluated as "hydrophobicity".

[0192] Hydrophobic powders can be obtained by treating the powders with, for example, a surface treatment agent that can exhibit hydrophobic properties.

[0193] Examples of such surface treatment agents include, for example, higher fatty acids, metallic soaps, oils, waxes, organosilicon compounds (e.g., carboxydecyltrisiloxane, polydimethylsiloxane, acrylic-organosilicon graft copolymers), fluorinated compounds, hydrocarbons, surfactants other than organosilicon surfactants described later, dextrin fatty acid esters (e.g., palmitic dextrin), polyglycerol fatty acid esters (e.g., tetraisostearate polyglycerol-2), amino acids (lauroyl lysine), distearate dimethyl ammonium chloride, and distearate dimethyl ammonium chloride. Here, higher fatty acids can refer to saturated or unsaturated fatty acids with 6 or more carbon atoms, specifically myristic acid, stearic acid, etc. Surface treatment agents can be used alone or in combination of two or more.

[0194] In several embodiments, where the cosmetic material of this disclosure comprises powder, unsaturated organopolysiloxane, and organosilicon surfactant, the powder, unsaturated organopolysiloxane, and organosilicon surfactant may be the same substances used in the above-described coating-type film-forming agents.

[0195] (water)

[0196] As for water, there are no particular restrictions; water used in cosmetics or pharmaceuticals can be used, for example. Examples of suitable water types include ion-exchanged water, distilled water, ultrapure water, and tap water.

[0197] There are no particular restrictions on the amount of water used in the mixing process; for example, it can be adjusted appropriately depending on the type of dosage form used.

[0198] Instructions for use of coating-type film-forming agents

[0199] The method of using the coating-type film-forming agent disclosed herein is not particularly limited, and may include any of the following steps. It should be noted that, since this method allows for the application of makeup to surfaces such as the face, it can also be referred to as a makeup method. Furthermore, the method of using the coating-type film-forming agent disclosed herein does not include methods for performing surgery, treatment, or diagnosis on a person. After applying the first agent to the target site (e.g., the body surface) to form a first agent layer, the second agent is applied on top of this first agent layer to form a film with a thickness of 50 μm or more. After applying the second agent to the target site (e.g., the body surface) to form a second agent layer, the first agent is applied on top of this second agent layer to form a film with a thickness of 50 μm or more. After mixing the first agent and the second agent to prepare a mixture, the mixture is applied to the target area (e.g., the body surface) to form a film with a thickness of 50 μm or more.

[0200] From the viewpoint of correcting depressions and achieving a natural makeup effect, the preferred method of application is to apply the first agent to the target area to form a first agent layer, and then apply the second agent on the first agent layer to cross-link and form a film. Here, the materials described above can be used for both the first and second agents.

[0201] This method can be performed in one step, or the formed film can be applied multiple times (e.g., two or more times). In the case of multiple applications, the method may include any of the following operations. According to this method, even when the viscosity of the coating-type film-forming agent is low, a film with a thickness of 50 μm or more can be formed: After applying the first agent to form a first agent layer, a second agent is applied to this first agent layer to further form a film, or... After applying the second agent to the formed film to form a second agent layer, the first agent is applied to this second agent layer to further form a film, or... After mixing the first agent and the second agent to prepare a mixture, the mixture is applied to the formed film to further form a film.

[0202] According to the coating-type film-forming agent of this disclosure, a film with a thickness of 50 μm or more can be formed. Therefore, the coating-type film-forming agent of this disclosure can also be referred to as a coating-type film-forming agent for forming a film with a thickness of 50 μm or more.

[0203] From the perspective of correcting concave defects and achieving a natural makeup effect, the thickness of the film can be set to 50μm or more, 70μm or more, 90μm or more, 100μm or more, 110μm or more, 120μm or more, 130μm or more, 140μm or more, or 150μm or more. There is no particular limit to this upper limit; it can be set to, for example, 300μm or less, 270μm or less, 250μm or less, 230μm or less, 200μm or less, 170μm or less, or 150μm or less. The thickness of the film can be appropriately adopted within this range. Here, the thickness can be defined as the average value calculated by measuring the thickness of any part of the film peeled from the target area five times using a high-precision digital micrometer (MDH-25MB, manufactured by Mitsutoyo Co., Ltd.). Although the surface of the film peeled off from the target area has tiny bumps and depressions that follow the concave defects such as pores, if the film thickness is obtained by this measurement method, the film can penetrate the concave defects such as pores and can play a role in correcting the area.

[0204] In several embodiments, the cosmetic material can be applied to the target area before applying the first agent, the second agent, or a mixture comprising the first agent and the second agent to the target area; the first agent layer can be formed by applying the first agent to the target area, and the second agent can be applied to the first agent layer to cover the cosmetic material; the second agent layer can be formed by applying the second agent to the target area, and the first agent can be applied to the second agent layer to cover the cosmetic material; or the cosmetic material can be applied to the film after it has been formed. In several embodiments, the coating-type film-forming agent of this disclosure can be used as a primer or a primer cosmetic material.

[0205] As a cosmetic ingredient, there are no particular restrictions. It can be used as a skin care cosmetic ingredient such as beauty serum, toner, lotion, sunscreen cosmetic ingredient, base cosmetic ingredient, or color cosmetic ingredient such as foundation, lip gloss, lipstick, eyeshadow, nail polish, or a cosmetic ingredient that combines the functions of two or more of these cosmetic ingredients.

[0206] The cosmetic material can be a powder cosmetic material. In this case, the ratio of water mass to the total mass of the cosmetic material (sometimes called moisture content) can be less than 50% by mass, less than 40% by mass, less than 30% by mass, less than 20% by mass, less than 15% by mass, less than 10% by mass, less than 5% by mass, less than 3% by mass, less than 2% by mass, less than 1% by mass, or less than 1% by mass. There is no particular restriction on the lower limit of this ratio; for example, it can be set to more than 0% by mass, more than 0% by mass, or more than 1% by mass.

[0207] The moisture content described above was determined by the weight loss under heating method. This moisture content was measured, for example, using a heated drying moisture meter (Aard Day MS-70, Co., Ltd.). More specifically, when the powder cosmetic does not substantially contain substances with a boiling point lower than water (for example, when the mass of substances with a boiling point lower than water is less than 5% by mass relative to the mass of the powder cosmetic), the moisture content described above was determined by the weight loss under heating method. On the other hand, when the powder cosmetic contains a specified amount or more of substances with a boiling point lower than water, the moisture content described above could be determined by near-infrared spectroscopy. As an example of the specified amount, 5% by mass is provided.

[0208] Furthermore, in several embodiments, the method of using the coating-type film-forming agent disclosed herein can also be used as a cosmetic procedure. For example, skin exposed to dryness sometimes loses moisture unknowingly, resulting in a lack of moisture retention in the stratum corneum. If the skin is not sufficiently moisturized, the skin's own moisturizing components (natural moisturizing factor (NMF)) cannot be produced effectively. As a result, the skin's barrier function and moisturizing function are reduced, making the skin more susceptible to damage, thus leading to loss of moisture and roughness.

[0209] On the other hand, for example, if a film formed by the coating-type film-forming agent of this disclosure is applied to the skin, the skin can be well moisturized through the occlusive effect (preventing moisture loss from the skin) produced by the film. As a result, for example, the skin's own ability to produce moisturizing components is improved, and the disorder of turnover in the stratum corneum is also improved, so problems such as rough skin are less likely to occur, thus improving the cosmetic effect. It should be noted that the so-called "cosmetic method" refers to applying the coating-type film-forming agent of this disclosure to a target area to form a film, and adjusting the condition of the target area (e.g., the face) to beautify it, which is different from methods of performing surgery, treatment, or diagnosis on a person.

[0210] There are no particular limitations on the method of applying the first or second agent to the target area, the cosmetic application layer, or the first or second agent layer. For example, it can be applied by spreading with fingers, spraying, or transferring.

[0211] Additionally, for example, when the first agent and / or the second agent are separated into water and oil, from the viewpoint of the cross-linking reactivity of the first agent and the second agent and the dispersibility of pigment-level particles in the film, it is preferable to shake these formulations to force them into a two-phase system (water-in-oil or oil-in-water).

[0212] <Target area>

[0213] The coating-type film-forming agent disclosed herein can be applied to all parts of the body, such as the surface of the skin (body surface). For example, the coating-type film-forming agent disclosed herein can be appropriately applied to the head, face (lips, eyes, nose, cheeks, forehead, etc.), neck, ears, hands, arms, legs, feet, chest, abdomen, back, buttocks, nails, etc. Here, the skin also includes hardened nails due to changes in the keratinization of the epidermis.

[0214] Kit with coating-type film-forming agent

[0215] The coating-type film-forming agent disclosed herein can be provided in the form of a kit having the aforementioned first agent and second agent constituting the forming agent. In addition to the first agent and second agent, the kit may also have, for example, a component for easily applying the first agent or the like to the target area, any component such as the aforementioned various cosmetics, or can be used in combination with any component.

[0216] Examples of arbitrary components include, for example, instruction manuals, scraper-shaped applicators, brushes, cotton swabs, knives, scissors, the aforementioned cosmetics, cleaning agents for removing the formed film from the target area, mirrors, etc. Here, "instruction manuals" can include not only general instruction manuals included in the kit in book form, but also substances such as packaging containers for storing the kit or tubes for injecting the first agent, for example, those with instruction text printed on them.

[0217] In one embodiment, regarding the kit, to prevent contact between the first and second agents, for example, these formulations may be encapsulated in different containers, or may be encapsulated separately in each region of a container having two or more regions. Furthermore, these encapsulated formulations may be configured to be applied one at a time, or may be configured to be mixed together before or during use.

[0218] In one embodiment, the kit can be used in combination with a cleaning agent for removing the formed film from the target area. "Combined use" here includes using the kit and cleaning agent as a single unit, i.e., the cleaning agent is contained within the kit, or using the kit and cleaning agent as separate components. For example, since it is possible to provide a coating-type film-forming agent and a cleaning agent best suited to an individual, it is preferable to use a kit containing a coating-type film-forming agent and a cleaning agent as separate components in combination.

[0219] <Cleanser>

[0220] The film formed on the target area by the coating-type film-forming agent of this disclosure can be properly removed from the target area using the specific remover described below. When using the specific remover of this disclosure, the strength of the film is not reduced, and therefore it can be peeled off from the target area in one step without damaging the film. Conventional sunscreen cosmetics, for example, require washing with a cleansing agent when removing cosmetics applied to the skin. On the other hand, the film obtained by the coating-type film-forming agent of this disclosure does not require such a process, and the film exhibiting UV protection properties can be peeled off from the target area (e.g., skin) more easily.

[0221] In several embodiments, a remover suitable for removing films formed by the coating-type film-forming agent of this disclosure comprises at least one selected from hydrocarbon oils with a weight-average molecular weight of 300 or more and 800 or less, and polar oils with a weight-average molecular weight of 260 or more and 400 or less. From the viewpoint of suitable film removal, it is preferable to use the hydrocarbon oil and the polar oil together.

[0222] (hydrocarbon oil)

[0223] From the viewpoint of being suitable for removing the film, the weight-average molecular weight of the hydrocarbon oil is preferably 320 or more or 350 or more, more preferably 380 or more, and preferably 750 or less or 700 or less, more preferably 690 or less. Hydrocarbon oils can be used alone or in combination of two or more.

[0224] There are no particular restrictions on the types of hydrocarbon oils, but examples include liquid paraffin (mineral oil), olefin oligomers and their hydrogenated derivatives (such as hydrogenated polydecene), and squalane.

[0225] There are no particular restrictions on the amount of hydrocarbon oil to be mixed in. For example, from the viewpoint of suitability for removing film, it can be set to 1.0% by mass or more, 5.0% by mass or more, 10% by mass or more, 20% by mass or more, or 30% by mass or more relative to the total amount of the composition constituting the cleaning agent. There are no particular restrictions on the upper limit of the amount to be mixed in. For example, it can be set to 100% by mass or less, less than 100% by mass, 80% by mass or less, 70% by mass or less, 60% by mass or less, or 50% by mass or less.

[0226] (Polar oil)

[0227] From the viewpoint of suitable film removal, the weight-average molecular weight of the polar oil is preferably 265 or higher or 270 or higher, and more preferably 390 or lower, 380 or lower, or 370 or lower. From the viewpoint of suitable film removal, the IOB value of the polar oil is preferably 0.12 or higher or 0.13 or higher, and more preferably 1.48 or lower, 1.47 or lower, or 1.46 or lower. Polar oils can be used alone or in combination of two or more.

[0228] There are no particular limitations on the types of polar oils, and ester oils can be cited as an example. Specific examples include isopropyl myristate (IOB value = 0.18), ethylhexyl ethylhexanoate (IOB value = 0.20), alkyl benzoate (C12-15) (IOB value = 0.18), diethylhexyl succinate (IOB value = 0.32), neopentyl glycol diheptanoate (IOB value = 0.33), triglycerides (caprylic / capric)glycerides (IOB value = 0.28), PPG-3 dinevalerate (IOB value = 1.46), and octyl palmitate (IOB value = 0.13).

[0229] There are no particular restrictions on the amount of polar oils used in the mixture. For example, from the viewpoint of suitability for removing film, it can be set to 1.0% by mass or more, 5.0% by mass or more, 10% by mass or more, 15% by mass or more, or 20% by mass or more relative to the total amount of the composition constituting the cleaning agent. There are no particular restrictions on the upper limit of the amount of polar oils used in the mixture. For example, it can be set to 100% by mass or less, less than 100% by mass, 80% by mass or less, 70% by mass or less, 60% by mass or less, or 50% by mass or less.

[0230] (Optional ingredients)

[0231] The cleaning agent disclosed herein can be appropriately blended with various ingredients within a range that does not adversely affect the removal effect on the skin film. Examples of such ingredients include, for instance, surfactants (emulsifiers), humectants, thickeners, water-soluble polymers, oil-soluble polymers, film-forming agents, higher fatty acids, metal ion blocking agents, lower alcohols, higher alcohols, polyols, modified alcohols, various extracts, sugars, amino acids, organic amines, polymeric emulsions, chelating agents, ultraviolet absorbers, pH adjusters, skin nutrients, vitamins, water-soluble agents applicable in pharmaceuticals, quasi-pharmaceuticals, cosmetics, etc., buffers, anti-fading agents, antioxidants, preservatives, dispersants, aerosols, fillers, pigments, dyes, colorants, fragrances, water, and other oils not mentioned above. Optional ingredients can be used alone or in combination of two or more.

[0232] The cleaning agent disclosed herein may contain oils other than the aforementioned hydrocarbon oils and polar oils. However, silicone oil may reduce the strength of the film, which may result in reduced film removal performance. Therefore, from the viewpoint of suitable film removal, the amount of silicone oil in the mixture is preferably 10% by mass or less, 5.0% by mass or less, 1.0% by mass or less, 0.5% by mass or less, or 0.1% by mass or less relative to the total amount of the composition constituting the cleaning agent. Furthermore, it is more preferable that the silicone oil is not included in the composition constituting the cleaning agent.

[0233] <How to use the cleaning agent>

[0234] There are no particular restrictions on how the cleaning agent is used. Generally, the cleaning agent can be applied to part or all of the film formed on the target area and optionally used by rubbing or the like. Then, the film can be removed by pulling it off the target area with fingers or the like.

[0235] Example

It should be noted that, unless otherwise specified, the mixing amount is expressed as a percentage by mass. Furthermore, the evaluation methods described in the examples are not limited to the forming agent and the film formed by that forming agent described in the examples; the same methods can be applied to the aforementioned forming agent and the film formed by that forming agent.

[0237] Evaluation Experiment 1

[0238] The following tests were conducted on the test samples obtained by the manufacturing method described below, and the results are shown in Table 2.

[0239] <Experiment on the Correction Effect of Concave Defects>

[0240] Biological skin (newly categorized by age group, cheek skin model, 30+ years old, manufactured by Beauty Racks Co., Ltd.) was prepared for commercial use as a high-performance artificial skin model. The first and second agents of the test sample were sequentially applied to this biological skin to form a film of a specified thickness. Under fluorescent light, the biological skin was placed on a table with the film side up. The film was observed with the eyes approximately 30 cm away from the film surface and the line of sight approximately 45 degrees relative to the film surface. The correction effect on the concave defects was evaluated according to the following criteria. The results are shown in Tables 2-3. Here, A-C evaluations are considered acceptable, and D-E evaluations are considered unacceptable. It should be noted that comparative examples 1-3 were not tested for the correction effect on concave defects because a film could not be formed. A: No shadow was observed around the concave defect (pore).

[0241] B: Very little shadow was observed around the concave defects (pores).

[0242] C: A slight shadow is observed around the concave defect (pore).

[0243] D: A shadow is clearly observed around the concave defect (pore).

[0244] E: Shadows are more clearly observed around concave defects (pores).

[0245] <Natural Makeup Effect Test>

[0246] Biological skin (new age-classified cheek skin model, 30+ years old, manufactured by Beauty Racks Co., Ltd.) was prepared for commercial use as a high-performance artificial skin model. The first and second agents of the test sample were sequentially applied to the biological skin to form a film of a specified thickness. Under fluorescent light, the biological skin was placed on a table with the film side up. The film was observed with the eyes approximately 30 cm away from the film surface and the line of sight approximately 45 degrees relative to the film surface. The natural makeup effect was evaluated according to the following criteria. The results are shown in Table 2. Here, A-C ratings are considered acceptable, and D-E ratings are considered unacceptable. It should be noted that Comparative Examples 1-3 could not form a film, and the correction effect for the concave defect in Comparative Example 4 was unacceptable; therefore, a natural makeup effect test was not conducted. A: For a natural makeup look.

[0247] B: A basic (around 90%) natural makeup look.

[0248] C: A generally natural makeup look (around 70%).

[0251] <Skin Formation Test>

[0252] Touch the film created on simulated skin in the above-mentioned modified test with your finger to confirm whether a film has formed that will not peel off even when touched with your finger. In the table, cases where such a film has formed are marked as "acceptable," and cases where such a film has not formed are marked as "unacceptable."

[0253] <Viscosity Evaluation Test>

[0254] The viscosity of the first agent in the test sample immediately after preparation was measured using a Type B viscometer (manufactured by Shibaura System Co., Ltd., Vismetron) at 25°C and 60 rpm (rotor No. 3 or No. 4). The results are shown in Tables 2 and 3.

[0255] Experimental Example 1

[0256] The test samples in this experimental example were prepared according to the following method. In this experimental example, the effect of pigment-grade particles with a refractive index of 2.0 or higher in the coating-type film-forming agent was studied. The results are shown in Table 2. It should be noted that "Mw" in the table refers to the weight-average molecular weight. In addition, the film thickness in each example and comparative example was the average value calculated by measuring the thickness of any part of the film peeled from simulated skin five times using a high-precision digital micrometer (MDH-25MB, manufactured by Mitsutoyo Co., Ltd.).

[0257] <Comparative Example 1>

[0258] (Dose 1)

[0259] The first agent was prepared by uniformly mixing vinyl polydimethylsiloxane (30.00 parts by weight) with a viscosity of 165,000 cst as the first unsaturated organopolypolysiloxane, volatile polydimethylsiloxane (balance) as oil, hydrophobically treated pigment-grade titanium oxide (0.05 parts by weight) as pigment-grade particles, and silylated silica (10.00 parts by weight) as hydrophobic inorganic oxide particles. It should be noted that hydrogen-functionalized polysiloxanes were not mixed into this first agent.

[0260] (Second dose)

[0261] The prescription ingredients in Table 1 are mixed evenly to prepare the second dose of 2-1.

[0262] [Table 1]

[0263] <Comparative Examples 2, 4, and 5 and Examples 1-4>

[0264] The components and their mixing amounts in the first preparation were changed to those listed in Table 2. Otherwise, all components were mixed at once in the same manner as in Comparative Example 1, and the first preparation was prepared by uniform mixing. The second preparation used the same substances as in Comparative Example 1.

[0265] <Comparative Example 3>

[0266] The components and their mixing amounts in Agent 1 were changed to those listed in Table 2. Otherwise, all components were mixed at once in the same manner as in Comparative Example 1, and Agent 1 was prepared by uniform mixing. Agent 2-2, which does not contain a catalyst, was used as Agent 2.

[0267] <Example 5>

[0268] The components and their mixing amounts in the first agent were changed to those listed in Table 2. Otherwise, all components were mixed at once in the same manner as in Comparative Example 1, and the first agent was prepared by uniform mixing. As the second agent, a second agent containing pigment-grade particles 2-3 was used.

[0269] [Table 2]

[0270] <Results>

[0271] As can be seen from the results of Comparative Examples 4 and 5 in Comparative Table 2 and Examples 1 to 4, it is evident that if pigment-grade particles are included in the range of 0.01% by mass or more and less than 1.5% by mass, the effect of correcting concave defects and the performance of natural makeup effect are improved.

[0272] Furthermore, it was found that in Example 5, which used a second agent containing pigment-grade particles, the correction effect on the concave defects was further improved compared to Example 1, which used a second agent without pigment-grade particles. Therefore, it can be concluded that if both the first and second agents contain pigment-grade particles, the correction effect on the concave defects is further improved.

[0273] Experimental Example 2

[0274] The test samples in this experimental example were prepared according to the following method. The effect on the thickness of the film was studied in this experimental example. The results are shown in Table 3.

[0275] <Example 6: Film thickness 50μm>

[0276] The ingredients and their mixing amounts in the first preparation were changed to those listed in Table 3. Otherwise, all ingredients were mixed at once in the same manner as in Comparative Example 1, and the first preparation was prepared by uniform mixing. The second preparation used 2-1 of Table 1.

[0277] <Example 7: Film thickness 100μm>

[0278] The ingredients and their mixing amounts in the first preparation were changed to those listed in Table 3. Otherwise, all ingredients were mixed at once in the same manner as in Comparative Example 1, and the first preparation was prepared by uniform mixing. The second preparation used 2-1 of Table 1.

[0279] [Table 3]

[0280] <Results>

[0281] As the results in Table 3 clearly show, the thicker the film, the better the correction effect on the concave defects.

[0282] Evaluation Experiment 2

[0283] The following tests were conducted on the test samples obtained by the manufacturing method described below, and the results are shown in Table 4.

[0284] <Evaluation of the appearance and coating color of the second agent (evaluation of powder dispersibility)>

[0285] The second agent was stirred for 10 minutes at 7,000 rpm using a homogenizer, and the appearance color immediately after stirring was visually confirmed. Next, the first agent (approximately 3g) was applied to a black plate using a spatula to form the first agent layer. The second agent (approximately 3g) was then applied to this first agent layer using the same spatula, and the color of the resulting second agent layer was visually confirmed. A "pass" rating was given if both the appearance color and the coating color were substantially uniform and largely consistent with each other; otherwise, a "fail" rating was given. It should be noted that in this experiment, since the focus was on the appearance color and coating color of the second agent, no catalyst was mixed into it.

[0286] Reference Examples 1-6 and Comparative Examples 1-11

[0287] <Dose 1>

[0288] The first agent was prepared by uniformly mixing 90 parts by weight of vinyl polydimethylsiloxane as the first unsaturated organopolysiloxane and 10 parts by weight of hydrogen polydimethylsiloxane as the first hydrogen-functionalized polysiloxane.

[0289] <Second dose>

[0290] The ingredients in Table 4 were mixed evenly to prepare the second dose.

[0291] [Table 4]

[0292] <Results>

[0293] The powder of the second agent in Reference Example 1, which does not contain a silicone surfactant, exhibited poor dispersibility, resulting in uneven color in both appearance and coating. On the other hand, the second agents in Reference Examples 1-3, which contain a silicone surfactant, and the second agents in Reference Examples 4-6, which have a higher powder ratio than the second agent, all showed excellent powder dispersibility, with no uneven color in appearance or coating, achieving a satisfactory evaluation level. It should be noted that while Reference Examples 1-3 were all satisfactory, the performance improved progressively in the order of PEG / PPG-19 / 19 polydimethylsiloxane, carboxydecyltrisiloxane, and bisbutyl polydimethylsiloxane polyglycerol-3, with bisbutyl polydimethylsiloxane polyglycerol-3 exhibiting the best performance.

[0294] The results from comparative examples 2-6 also confirmed that no effect could be obtained by using surfactants other than silicone surfactants and dispersants.

[0295] Furthermore, the results from comparative examples 7-11 also confirmed that even if the proportion of powder is reduced, no effect can be obtained by using surfactants other than silicone surfactants and dispersants.

[0296] Example of a prescription for the second dose

[0297] The following are examples of formulations for the second agent of the coating-type film-forming agent disclosed herein, but are not limited to these examples. It should be noted that the second agent described in the following formulations also exhibits excellent powder dispersibility, and no color unevenness is observed in the appearance and coating color, achieving a satisfactory evaluation result.
