Description

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

This disclosure relates to a coating-type film-forming agent, a kit containing the agent, and a method for using the agent.

　There are known coating agents 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.

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.

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

Patent Document 3, Patent Document 4, and Patent Document 5 disclose a film-forming agent that includes a first agent that contains a cross-linking reactive component and water, and a second agent that contains a cross-linking component for cross-linking the cross-linking reactive component. These documents also disclose that the film-forming agent can contain various powders.

Special table 2019-503396 publication JP 2009-155211 A International Publication No. 2022/215531 International Publication No. 2022/215533 International Publication No. 2022/124079

When the applied 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 warp. For this reason, such agents typically stretch wrinkles and other concave portions in the skin, reducing the size of the concave portions, thereby making defects such as wrinkles less noticeable, but there are cases in which this stretching action alone is insufficient to make the concave defects less noticeable.

　Conventional cosmetics for correcting pores, such as those described in Patent Document 2, were sometimes insufficiently effective or produced an unnatural finish.

Therefore, there was a need for the development of a paint-on film-forming agent that has an excellent effect of correcting pores and other concave defects and also provides a natural finish.

Therefore, according to one aspect of the present disclosure, a paint-type film-forming agent can be provided that has an excellent effect of correcting recess defects such as pores and is capable of forming a film that provides a natural finish.

In addition, when a powder such as a pigment is blended with a coating-type film-forming agent or cosmetic that contains an unsaturated organopolysiloxane such as vinyl dimethicone, the dispersibility of the powder in the film-forming agent or cosmetic may decrease.

Accordingly, according to another aspect of the present disclosure, a paint-type film-forming agent or cosmetic containing an unsaturated organopolysiloxane can be provided that can improve the dispersibility of powders.

The following describes in detail the embodiments of the present disclosure. The present disclosure is not limited to the embodiments below, and can be modified in various ways within the scope of the invention.

The coating-type film-forming agent according to one embodiment of the present disclosure includes a first agent containing a cross-linking reactive component that constitutes a film, and a second agent containing a catalyst that cross-links the cross-linking reactive component, and the first agent and/or the second agent contains 0.01% by mass or more and less than 1.5% by mass of pigment-grade particles having a refractive index of 2.0 or more.

Although not limited by the theory, the principle of action of the applied film-forming agent disclosed herein is believed to be as follows, which has an excellent effect of correcting defects in recesses such as pores and is capable of forming a film that provides a natural finish.

As shown in Figure 1(a), in a concave defect such as a pore, the light incident on the defect (indicated by the arrow in the figure) hits the wall of the concave and shifts direction, creating a shadow, which is thought to make the defect more noticeable.

For example, conventional cosmetics with pore correction capabilities contain a lot of pigment, which hides pores when applied. Therefore, although it is possible to make pores less noticeable, it can sometimes result in an unnatural finish. Also, for example, cosmetics with low pigment content can have a relatively low viscosity. In such cases, as shown in Figure 1(b), it is difficult to apply thickly, and as a result, the recesses cannot be filled sufficiently, so shadows are created as in the case of Figure 1(a), and the defects are likely to be noticeable. Also, even if a thickener or the like is used to increase the viscosity of cosmetics with low pigment content, conventional cosmetics can sometimes cause the makeup to come off after application, resulting in an unnatural finish.

In one embodiment of the present disclosure, at least one of the first and second agents that can constitute the coating agent contains 0.01% by mass or more and less than 1.5% by mass of pigment-class particles having a refractive index of 2.0 or more. The inventors have found that coating agent containing pigment-class particles with such a high refractive index can be applied thicker to fill pores and other defects than general cosmetics, as shown in FIG. 1(c), and therefore can exhibit an excellent correction effect on defects in recesses even when the amount of pigment-class particles is low. It is believed that this effect is exhibited by the high refractive index pigment-class particles being arranged so that they can reflect light approximately specularly in the coating that fills the recesses. In addition, the amount of pigment-class particles in the coating is relatively small, and the coating applied to the skin, etc. is crosslinked, and the coating is less likely to break down like conventional cosmetics, so that the formed coating has a natural finish. In the simulation results of Figures 1(b) and (c), the recessed defect (pore) part is white, but this is to make the position and shadow of the recessed defect easier to see. In an actual film, if the color of the film is adjusted using a coloring material, the white part can be made less noticeable.

In addition, when a typical cosmetic is applied to the skin, the pigment-class particles become fluid due to the effects 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 the depression defect over time. Therefore, even if a cosmetic contains a low concentration of high refractive index pigment-class particles and can be applied thickly, it is thought that such a cosmetic would not be able to fully correct the depression defect or provide a natural finish.

On the other hand, the film produced by the application-type 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 reactive component that constitutes the film, and a second agent containing a catalyst that crosslinks the crosslinkable reactive component. As a result, the pigment-class particles contained in the film are fixed in a uniformly dispersed state within the film, and it is believed that this can more effectively correct recess defects and provide a more natural finish than the conventional cosmetics described above.

Furthermore, for example, conventional cosmetics having pore correction capabilities have also had the problem that the cosmetics applied to the skin tend to peel off due to sweat or rubbing. The applied-type film-forming agent of the present disclosure can be applied to the skin to crosslink and form a film, and the resulting crosslinked film has superior resistance to peeling off due to rubbing, etc., compared to films obtained by applying conventional cosmetics to the skin. Therefore, it is believed that the applied-type film-forming agent according to one embodiment of the present disclosure can also contribute to solving the problem of conventional cosmetics peeling off.

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

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

In this disclosure, "viscosity" refers to a measure of the resistance of a fluid to being deformed by either shear or tensile stress. For example, the viscosity of the first and second parts of a paint-on film former affects the thickness, spreadability, and uniformity and/or uniformity of the layer formed on a substrate. Viscosity can be reported as either 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, cst), which is the dynamic viscosity divided by the density of the measured fluid. The viscosity ranges of the components disclosed herein are generally provided by the suppliers of each component in units of kinematic viscosity (e.g., cst) measured using a rheometer or a Cannon-Fenske tube viscometer, although the viscosity of a fluid can also be measured using, for example, a rheometer (e.g., a linear shear rheometer or a dynamic shear rheometer) or a viscometer (a viscometric meter, also called a capillary viscometer or a rotational viscometer).

In this disclosure, "crosslinking" also includes the concept commonly referred to as "curing."

In this disclosure, the term "target area" refers to the area in which correction of the recess defect is desired to occur.

In the present disclosure, "correction of concave defects" refers to making concave defects in the skin less noticeable after application of a film made from the applied-type film-forming agent of the present disclosure, or to concealing such concave defects. In the present disclosure, "concave defects" refers to concave defects in the body (e.g., pores, skin grooves, wrinkles, scars, etc.). Here, "concave defects in the body" can mean, for example, concave parts of the body that are of concern to the subject, or concave parts of the body that the subject feels would like to fix, or concave parts of the body of the subject that a person skilled in the art, for example, a dermatologist, esthetician, or plastic surgeon, believes should be fixed. There is no particular limit to the maximum depth of the concave from the skin surface, and it 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 this 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.

In this disclosure, "pigment-grade" is intended to mean a size that can 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 the average particle size 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 if the titanium dioxide particles are the same type, titanium dioxide particles with an average particle size of 300 nm can be treated as pigment-grade particles, and titanium dioxide particles with an average particle size of 80 nm can be treated as ultraviolet scattering particles, etc.

<<Coating-type film-forming agent>>
In one embodiment of the present disclosure, the paint-on film-forming agent (sometimes simply referred to as a "former") includes, for example, a first agent containing a crosslinking reactive component that constitutes a film, and a second agent containing a catalyst that crosslinks the crosslinking reactive component. At least one of the first agent and the second agent contains 0.01% by mass or more and less than 1.5% by mass of pigment-grade particles having a refractive index of 2.0 or more. According to one embodiment of the present disclosure, the paint-on film-forming agent has an excellent correction effect on recess defects such as pores, and therefore can be suitably used for recess defects in the skin, particularly for pore correction.

In some embodiments, the application performance of the paint-on film-forming agent can be evaluated by viscosity using a Brookfield viscometer (Shibaura Systems Co., Ltd., Vismetron). The viscosity of the first and second agents immediately after preparation in the paint-on film-forming agent according to one embodiment of the present disclosure, 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, and can be 1,000,000 mPa·s or less, 750,000 mPa·s or less, 500,000 mPa·s or less, 250,000 mPa·s or less, 200,000 mPa·s or less, 175,000 mPa·s or less, 150,000 mPa·s or less, 125,000 mPa·s or less, 100,000 mPa·s or less, or 80,000 mPa·s or less. In particular, from the viewpoint of smooth application performance and suppression of dripping from the target site, the first and second agents of the application-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., from the viewpoint of obtaining a film having a thickness of, for example, 50 μm or more), at least one of the first and second agents in the application-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. 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.

In some embodiments, the viscosity of the first and second agents in 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.

In another embodiment, the paint-type film-forming agent (sometimes simply referred to as a "forming agent") 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 the first agent and the second agent. The powder may include pigment-grade particles (sometimes simply referred to as "pigment-grade particles") having a refractive index of 2.0 or greater. The powder may include particles different from the pigment-grade particles.

In addition, 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., the first or second agent), the system containing the unsaturated organopolysiloxane and the powder may further contain a silicone-based surfactant. This can improve the dispersibility of the powder.

<First Agent>
In one embodiment of the present disclosure, the paint-type film-forming agent includes a first agent that includes a crosslinking reactive component that forms a film.

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

(Pigment-grade particles with a refractive index of 2.0 or greater)
From the viewpoint of the effect of correcting recess defects and natural finish performance, 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.

When the first agent contains such pigment-class particles, the amount of the pigment-class particles is preferably 0.01% by mass or more, or 0.02% by mass or more, and more preferably 0.03% by mass or more, 0.04% by mass or more, or 0.05% by mass or more, based on 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.

There are no particular limitations on the pigment-grade particles as long as they have a refractive index of 2.0 or more. 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 viewpoint of the effect of correcting recess defects and natural finish performance. The pigment-grade particles can be used alone or in combination of two or more kinds.

Here, in this 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, iron oxide-coated titanium mica, carmine-coated titanium mica, carmine- and malt-coated titanium mica, iron oxide- and carmine-treated titanium mica, malt-coated titanium mica, iron oxide- and malt-coated 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 ocher titanium oxide-coated mica, which is mica coated with iron oxide and titanium oxide, and hollow titanium oxide powder with silica sandwiched between the mica and titanium oxide coating layer.

　Colorless pearlescent pigments can also be used as pearlescent pigments. Such pearlescent pigments can be known as transparent pearlescent pigments (transparent lustrous pigments). For example, pearlescent pigments can be made by forming a coating made of a high refractive index material such as titanium oxide on the surface of glass particles as a base material.

Pigment-grade particles may be subjected to a hydrophobic treatment. Pigment-grade particles that have been hydrophobized (hydrophobic pigment-grade particles) tend to disperse evenly in the coating, which can improve the effect of correcting recess defects and the natural finish performance.

There are no particular limitations on the hydrophobic treatment of pigment-grade particles, and any treatment that modifies the surface of such particles with an organic compound to make them hydrophobic can be used, 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 examples include lecithin treatments; metal soap treatments; fatty acid treatments; and alkyl phosphate ester treatments. The hydrophobic treatments can be used alone or in combination. The hydrophobic treatment can also be carried out using a hydrophobic treatment agent.

Examples of silicones that can be used as hydrophobic treatment agents include known silicones that have hydrogen-silicon bonds, such as methylhydrogenpolysiloxane (dimethicone/methicone) copolymer. Other examples include triethoxysilylethyl polydimethylsiloxyethyl dimethicone and triethoxysilylethyl polydimethylsiloxyethylhexyl dimethicone, which have an alkoxy group-silicon bond as a reactive group. In addition, dimethylpolysiloxane can also be used.

Silane-based treatment agents include, for example, silylating agents with organic groups introduced therein and silane coupling agents, such as triethoxycaprylylsilane.

Titanate-based treatment agents include, for example, titanium coupling agents such as alkyl titanates, pyrophosphate-type titanates, phosphorous-type titanates, and amino acid-type titanates.

In some embodiments, the first agent of the present disclosure contains at least one selected from the group consisting of a first unsaturated organopolysiloxane and a first hydride-functionalized polysiloxane as such a crosslinking reactive component. From the viewpoint of obtaining a good coating, when the first agent contains only the first unsaturated organopolysiloxane among the first unsaturated organopolysiloxane and the first hydride-functionalized polysiloxane, the second agent in the forming agent of the present disclosure contains the second hydride-functionalized polysiloxane, and when the first agent contains only the first hydride-functionalized polysiloxane among the first unsaturated organopolysiloxane and the first hydride-functionalized polysiloxane, it is preferable that the second agent 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.

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 this disclosure, "anhydrous" not only means that the composition does not contain water, but also means that the water content is low, 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. In addition, a non-emulsified two-phase system may include a water-in-oil composition in which water droplets are forcibly dispersed in a dispersion medium containing oil by shaking a liquid in a state in which the water and oil are separated, or an oil-in-water composition in which oil droplets are forcibly dispersed in a dispersion medium containing water.

Each of these formulations can be prepared appropriately by conventional methods using a crosslinking reactive component and, optionally, known materials such as oils, emulsifiers, and water, as described below.

The first agent is applied to the target area (e.g., the face) by painting, etc., and therefore, from the viewpoint of application performance, it preferably has a glass transition temperature below body temperature. For example, the glass transition temperature can be 37°C or lower, 25°C or lower, 10°C or lower, or 0°C or lower. There is no particular restriction on the lower limit of the glass transition temperature, but it can be, for example, -30°C or higher, -20°C or higher, or -10°C or higher. Here, "glass transition temperature" refers to the temperature at which a transition from a solid state to a liquid state occurs, and can be measured, for example, using a differential scanning calorimeter (DSC) in accordance with ASTM D3418-03.

(First Unsaturated Organopolysiloxane)
The first unsaturated organopolysiloxane is not particularly limited, and may be an organopolysiloxane having an unsaturated portion, for example, one or more organopolysiloxanes having at least two carbon-carbon double bonds or at least one carbon-carbon triple bond in the molecule. As such an unsaturated organopolysiloxane, preferably, one or more organopolysiloxanes having at least two alkenyl functional groups (e.g., vinyl functional groups) on average and having a viscosity of 1,000 to 2,000,000 cst at 25°C may be mentioned. Here, the "unsaturated portion" in the present disclosure means a portion having a "carbon-carbon double bond" and a "carbon-carbon triple bond", which may be simply referred to as a "double bond" and a "triple bond". The first unsaturated organopolysiloxane may be used alone or in combination of two or more kinds.

The first hydride-functionalized polysiloxane can be used appropriately within such ranges.

<Second Agent>
The second agent constituting the coating-type film-forming agent of the present disclosure contains a catalyst that crosslinks the crosslinking reactive component in the first agent described above. The second agent of the present disclosure may contain pigment-class particles having a refractive index of 2.0 or more, as in the first agent. If both the first agent and the second agent contain such pigment-class particles in the range of 0.01 mass% or more and less than 1.5 mass%, respectively, the pigment-class particles are more likely to be arranged near the surface of the film, and light incident on the film is more likely to be reflected near the surface of the film, so that the effect of correcting the recess defect can be further improved. In this case, if the second agent further contains an unsaturated organopolysiloxane (second unsaturated organopolysiloxane), the pigment-class particles are more likely to be arranged near the surface of the film, and are more likely to be fixed near the surface, so that the effect of correcting the recess defect can be further improved.

(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 crosslinking 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.

The catalyst may be, but is not limited to, a metal catalyst capable of initiating and/or promoting 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. Of these, platinum catalysts, rhodium catalysts, and tin catalysts are preferred. The catalysts may be used alone or in combination of two or more.

Platinum catalysts include, for example, platinum carbonylcyclovinylmethylsiloxane complexes, platinum divinyltetramethyldisiloxane complexes, platinum cyclovinylmethylsiloxane complexes, platinum octanaldehyde/octanol complexes, and other Pt(0) catalysts, such as Karstedt's catalyst, platinum-alcohol complexes, platinum-alkoxide complexes, platinum-ether complexes, platinum-aldehyde complexes, platinum-ketone complexes, platinum-halogen complexes, platinum-sulfur complexes, platinum-nitrogen complexes, platinum-phosphorus complexes, platinum-carbon double bond complexes, platinum-carbon triple bond complexes, platinum-imido complexes, platinum-amide complexes, platinum-ester complexes, platinum-phosphate ester complexes, platinum-thiol ester complexes, platinum lone pair complexes, platinum-aromatic complexes, platinum π-electron complexes, and combinations thereof. Among these, at least one selected from the group consisting of platinum carbonylcyclovinylmethylsiloxane complex, platinum divinyltetramethyldisiloxane complex, platinum cyclovinylmethylsiloxane complex, and platinum octanaldehyde/octanol complex is preferred.

Rhodium catalysts include, for example, tris(dibutylsulfide)rhodium trichloride and rhodium trichloride hydrate.

Examples of tin catalysts include tin(II) octanoate, tin(II) neodecanoate, dibutyltin diisooctylmaleate, di-n-butyl bis(2,4-pentanedionate)tin, di-n-butylbutoxychlorotin, dibutyltin dilaurate, dimethyltin dineodecanoate, dimethylhydroxy(oleate)tin, and tin(II) oleate.

Among these catalysts, platinum catalysts are more preferred, with platinum divinyltetramethyldisiloxane complex (sometimes called "platinum divinyldisiloxane") being particularly preferred.

The amount of catalyst in the second agent can be adjusted appropriately according to the required film performance, etc., and there are no particular restrictions. For example, the amount of catalyst can be 0.001 mass% or more, 0.005 mass% or more, or 0.010 mass% or more, and 5.0 mass% or less, 3.0 mass% or less, 1.0 mass% or less, 0.10 mass% or less, or 0.050 mass% or less, relative to the total amount of the second agent. The catalyst can be used appropriately within such ranges.

The formulation of the second agent of the present disclosure is not particularly limited, and may be, for example, a single-phase system composed 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 composed of an oil-in-water emulsion composition or a water-in-oil emulsion composition.

Each of these formulations can be prepared appropriately by conventional methods using a catalyst and, optionally, known materials such as oil, emulsifier, and water, as described below. 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 may be used as this silicone oil. In this case, the unsaturated organopolysiloxane and the hydride-functionalized polysiloxane in the second agent can be called the second unsaturated organopolysiloxane and the second hydride-functionalized polysiloxane to distinguish them from the first unsaturated organopolysiloxane and the first hydride-functionalized polysiloxane in the first agent.

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

Here, some of the main optional ingredients are described in detail below.

(Inorganic particles)
In some embodiments, at least one of the first and second agents, preferably the first agent, of the paint-on film-forming agent of the present disclosure contains inorganic particles other than the pigment-grade particles described above, such as hydrophobized inorganic oxide particles. The use of hydrophobized inorganic oxide particles can increase the viscosity of the paint-on film-forming agent, which can contribute to thick coating and can also contribute to improving the strength of the film.

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, from the viewpoint of thickening the film and obtaining good film strength. There is no particular limit to 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.

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.

The hydrophobized inorganic oxide particles can typically be inorganic oxide particles that have been hydrophobized with a surface treatment agent. There are no particular limitations on the hydrophobization treatment, and from the standpoint of thickening the film and obtaining good film strength, for example, at least one treatment selected from the group consisting of dimethylsilylation and trimethylsilylation is preferred.

The amount of inorganic particles (e.g., hydrophobized inorganic oxide particles) 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 relative to the entire first or second agent, 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. Inorganic particles (e.g., hydrophobized inorganic oxide particles) can be used appropriately within such ranges.

(Oil content)
Examples of oils include liquid oils, solid oils, waxes, hydrocarbon oils, ester oils, silicone oils, and polar oils. The oils may be non-volatile or volatile oils. The oils may be used alone or in combination. Here, "volatile" refers to oils that exhibit a volatile content of more than 5% when left at atmospheric pressure and 105°C for 3 hours. Such volatile content can also 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 250°C or less, 240°C or less, or 230°C or less, and can be 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.

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 that can be used 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 and vinyl groups, and can therefore be suitably blended with the first agent and/or the second agent that contains unsaturated organopolysiloxanes having phenyl and vinyl groups.

The amount of oil (e.g., silicone oil) to be blended is not particularly limited, and can be blended appropriately depending on, for example, the type of formulation used and the required film strength. 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 entire 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.

(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 called surfactants.

Specific examples of the emulsifier include at least one selected from the group consisting of hydrocarbon surfactants, silicone surfactants, and amphiphilic powders.

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.

Examples of silicone surfactants include polyether-modified silicone and alkyl-co-modified polyether-modified silicone.

There are no particular restrictions on the amount of emulsifier used, and from the standpoint of emulsion stability, for example, 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 agent or the second agent. There are no particular restrictions on the upper limit of the amount of emulsifier used, 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 these ranges.

(Silicone surfactant)
As described above, the apply-type film-forming agent may include a powder. The powder may include the pigment-grade particles having a refractive index of 2.0 or more as described above, or may be substantially free of the pigment-grade particles. When the powder includes the pigment-grade particles as described above, 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 weight or more and less than 1.5% by weight.

In some embodiments, when a powder is blended together 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-based surfactant into the system containing them. In view of the fact that the mixture of an unsaturated organopolysiloxane and a powder further contains a silicone-based surfactant, the ratio of the mass of the pigment-grade particles to the mass of the paint-on film-forming agent may be less than 0.01% by mass or more than 1.5% by mass.

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). On the other hand, the silicone-based surfactant used in the forming agent disclosed herein is different from such general dispersants in that it is believed to act not on the powder but on the unsaturated organopolysiloxane.

For example, as shown in Figure 2(a), when powder and unsaturated organopolysiloxane are mixed in the oil phase, the unsaturated organopolysiloxane acts to aggregate the powder, which is believed to reduce the dispersibility of the powder. Therefore, even if a general dispersant that acts on powders is mixed into such a system, it is believed that a sufficient dispersion effect will be difficult to obtain.

On the other hand, the silicone surfactant blended into the forming agent of the present disclosure has excellent affinity with the unsaturated organopolysiloxane, which can act as an agglomerating agent for the powder, and it is believed that the hydrophobic groups of this silicone surfactant interact with the unsaturated organopolysiloxane and disperse in the oil phase in a form similar to an inverted micelle, as shown in Figure 2(b). As a result, the powder agglomerating action of the unsaturated organopolysiloxane is reduced, and the dispersibility of the powder in the forming agent is improved. Here, the black bars of the silicone surfactant in Figure 2(b) represent hydrophobic groups, and the white spheres represent hydrophilic groups.

In some embodiments, the amount of silicone surfactant in the first or second agent in the 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 entire first or second agent. The silicone surfactant can be used appropriately within such ranges.

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

Silicone surfactants can be used alone or in combination.

As the silicone surfactant, for example, from the viewpoint of improving the dispersibility of the 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 restriction on the lower limit of the HLB, 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. Among them, from the viewpoint of improving the dispersibility of the powder, the HLB value is preferably 0.1 or more and 7.0 or less. Here, "HLB" is a value that generally indicates the affinity to water and oil, and is a parameter known as the hydrophilic-lipophilic balance. The HLB value of the silicone surfactant can be easily determined by the Griffin method. Here, the HLB value by the Griffin method can be determined by the following formula a:
HLB value = 20 x sum of formula weights of hydrophilic parts / molecular weight ... formula a

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

(Polyglycerin/alkyl-modified silicone)
Examples of polyglycerin-alkyl-comodified silicones include bis-butyl dimethicone polyglyceryl-3 and cetyl PEG/PPG-10/1 dimethicone, where "PEG" and "PPG" refer to polyethylene glycol and polypropylene glycol, respectively.

(Carboxy modified silicone)
An example of the carboxy-modified silicone is carboxydecyltrisiloxane.

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

<Powder>
In some embodiments, the paint-on film-forming agent or cosmetic of the present disclosure comprises a powder. The powder may be used alone or in combination.

In some embodiments, the amount of powder varies and can be set appropriately depending on the application of the cosmetic. The amount of powder 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, 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, based on the total amount of the applied-type film-forming agent (e.g., the first agent or the second agent) or the cosmetic. The amount of powder can be appropriately blended in the applied-type film-forming agent or the cosmetic within such ranges.

In some embodiments, the amount of powder in the applied film-forming agent (e.g., the first or second agent) or cosmetic can be specified as a ratio to 100 parts by weight of the total of the powder, the unsaturated organopolysiloxane, and the silicone-based surfactant. In this case, the amount of powder can be 10 parts by weight or more, 15 parts by weight or more, 20 parts by weight or more, 25 parts by weight or more, or 27 parts by weight or more, and can be 60 parts by weight or less, 55 parts by weight or less, 50 parts by weight or less, or 47 parts by weight or less, per 100 parts by weight of the total of the powder, the unsaturated organopolysiloxane, and the silicone-based surfactant.

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 agent or the second agent) or the cosmetic may contain only spherical powders or only non-spherical powders, or may contain both spherical and non-spherical powders.

In some embodiments, the applied film-forming agent or cosmetic of the present disclosure includes a spherical powder. There are no particular limitations on the size of the spherical powder. 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 powders having an average particle size in such ranges can be used alone or in combination of two or more kinds.

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 shape is spherical.

In some embodiments, the applied film-forming agent or cosmetic of the present disclosure includes a non-spherical powder. The non-spherical powder is intended to be a powder that is not included in the spherical powder described above, and can be defined, for example, by the 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. The non-spherical powder can be used alone or in combination of two or more types of powders having aspect ratios in such ranges.

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

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

　Examples of components constituting the inorganic powder include talc, kaolin, mica (e.g., sericite (sericite), muscovite, phlogopite, synthetic mica, synthetic iron phlogopite, red mica, biotite), calcined talc, calcined mica (e.g., calcined sericite, calcined muscovite, calcined phlogopite), permiculite, magnesium carbonate, calcium carbonate, aluminum silicate, barium silicate, calcium silicate, magnesium silicate, strontium silicate, Ca/Aluminum borosilicate, metal salts of 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, aluminum stearate, etc.), boron nitride, photochromic titanium oxide (titanium dioxide sintered with iron oxide), and reduced zinc oxide. 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.

Other inorganic powders that can be used include inorganic pigments (sometimes referred to as "inorganic colored pigments"). Examples of inorganic pigments include inorganic white pigments (e.g., titanium dioxide, zinc oxide); inorganic red pigments (e.g., iron oxide (red oxide), iron titanate); inorganic brown pigments (e.g., gamma-iron oxide); inorganic yellow pigments (e.g., yellow iron oxide, yellow ocher); 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 luster powders. Examples of such glittering powders include pearl pigments (e.g., bismuth oxychloride, fish scale foil, titanium mica, titanium mica coated with iron oxide, titanium mica coated with low-order titanium oxide, titanium mica having photochromic properties, substrates using talc, glass, synthetic fluorine phlogopite, silica, bismuth oxychloride, etc. instead of mica, coatings coated with low-order titanium oxide, colored titanium oxide, iron oxide, alumina, silica, zirconia, zinc oxide, cobalt oxide, aluminum, etc. in addition to titanium oxide, functional pearl pigments coated with resin particles, coated with aluminum hydroxide particles, coated with zinc oxide particles, and coated with barium sulfate particles); and metal powder pigments (e.g., aluminum powder, copper powder).

The components constituting the organic powder include, for example, silicone elastomer, silicone, silicone resin-coated silicone elastomer, polyamide resin (e.g., nylon), polyolefin resin (e.g., polyethylene), polymethylmethacrylate, polystyrene, copolymer resin of styrene and acrylic acid, benzoguanamine resin, fluororesin (e.g., polytetrafluoroethylene), starch (e.g., starch aluminum octenylsuccinate), crosspolymers such as (HDI/trimethylolhexyllactone) crosspolymer, (diphenyl dimethicone/vinyl diphenyl dimethicone/silsesquioxane) crosspolymer, and (IPDI/poly(1,4-butanediol)-14) crosspolymer, and cellulose.

Other than the above, organic powders may be, for example, organic pigments (sometimes referred to as "organic coloring pigments") and/or dyes. Examples of organic pigments include organic pigments such as zirconium, barium, or aluminum lake, specifically, for example, organic pigments such as 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, 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.

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

In some embodiments, the applied film-forming agent or cosmetic of the present disclosure includes a hydrophobic powder. The hydrophobic powder is suitable when the powder is dispersed in an oil phase. The hydrophobic powder can be used alone or in combination of two or more kinds.

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

Hydrophobic powders can be obtained by treating the above-mentioned powders with, for example, a surface treatment agent that can provide hydrophobic properties.

Such surface treatment agents include, for example, 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 refer to 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 may be used alone or in combination of two or more.

In some embodiments, when the cosmetic composition of the present disclosure contains a powder, an unsaturated organopolysiloxane, and a silicone-based surfactant, the powder, the unsaturated organopolysiloxane, and the silicone-based surfactant may be the same as those used in the above-mentioned applied film-forming agent.

(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.

There are no particular limitations on the amount of water to be added, and it can be adjusted as appropriate depending on, for example, the type of formulation used.

How to use the coating agent
The method of using the applied-type film-forming agent of the present disclosure is not particularly limited, and may include, for example, any of the following steps. Note that, according to this method, for example, makeup can be applied to the face, and therefore the method can also be called a makeup method. In addition, the method of using the applied-type film-forming agent of the present disclosure does not include methods for surgery, treatment, or diagnosis of humans:
Applying the first agent to a target site (e.g., a body surface) to form a first agent layer, and then applying the second agent onto the first agent layer to form a coating having a thickness of 50 μm or more; or
The second agent is applied to the target site (e.g., the body surface) to form a second agent layer, and then the first agent is applied onto the second agent layer to form a film having a thickness of 50 μm or more; or, the first agent and the second agent are mixed to prepare a mixture, and then the mixture is applied to the target site (e.g., the body surface) to form a film having a thickness of 50 μm or more.

From the viewpoint of correcting the recess defects and achieving a natural finish, the preferred method of use is to apply the first agent to the target area to form a layer of the first agent, and then apply the second agent onto the first agent layer and crosslink the layer to form a film. Here, the materials described above can be used for the first and second agents in the same manner.

This method may be performed once, or may be performed multiple times (e.g., two or more times, or three or more times) on the formed coating. 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-type film-forming agent is low, a coating having a thickness of 50 μm or more can be formed:
Applying a first agent to the formed coating to form a first agent layer, and then applying a second agent onto the first agent layer to further form a coating; or
An operation of applying a second agent to the formed coating to form a second agent layer, and then applying a first agent onto the second agent layer to further form a coating; or an operation of mixing the first agent and the second agent to prepare a mixture, and then applying the mixture to the formed coating to further form a coating.

The coat-type film-forming agent of the present disclosure can form a film having a thickness of 50 μm or more. Therefore, the coat-type film-forming agent of the present disclosure can also be called a coat-type film-forming agent for forming a film having a thickness of 50 μm or more.

The thickness of the coating may 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, from the viewpoint of the effect of correcting recess defects and natural finish performance. There is no particular limit to the upper limit of the thickness, and it may 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 may be appropriately adopted within such a range. Here, the thickness may be defined as the average value calculated by measuring the thickness of any part of the coating peeled off from the target part five times using a high-precision digital 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 if the film thickness is measured using this method, the film will penetrate into the pores and other concave defects and have the effect of correcting the area.

In some embodiments, a cosmetic may be applied to the target site before applying the first agent, the second agent, or a mixture containing the first agent and the second agent to the target site; a first agent may be applied to the target site to form a first agent layer, a cosmetic may be applied on the first agent layer, and the second agent may be applied to cover the cosmetic; a second agent may be applied to the target site to form a second agent layer, a cosmetic may be applied on the second agent layer, and 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 base cosmetic.

There are no particular limitations on the cosmetics, and examples of the cosmetics that can be used include skin care cosmetics such as serums, lotions, and emulsions, sunscreen cosmetics (sun protection cosmetics), base cosmetics, or make-up cosmetics such as foundations, glosses, lipsticks, eye shadows, and nail polishes, or cosmetics that combine the functions of two or more of these cosmetics.

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 limit to the lower limit of such a ratio, and it may be, for example, 0% by mass or more, more than 0% by mass, or 1% by mass or more.

The moisture content is measured by the heat loss method. The moisture content is measured, for example, using a heat-dry moisture meter (MS-70, 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 the substance with a boiling point lower than that of water to the mass of the powder cosmetic is less than 5 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 mass%.

Furthermore, in some embodiments, the method of using the applied film-forming agent of the present disclosure can also be used as a cosmetic method. 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 does not have enough moisture, it is no longer able 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 reduced, making the skin more susceptible to damage, which is thought to cause a loss of moisture and lead to rough skin, etc.

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 from escaping 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 turnover problems in the stratum corneum are also improved, making skin problems such as roughness less likely to occur, and improving the beauty effect. Note that a "beauty method" refers to applying the applied film-forming agent of the present disclosure to a target area to form a film and beautify the condition of the target area (for example, the face), and is different from a method of surgery, treatment, or diagnosis of a human.

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, transfer, etc. can be used.

Also, 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 make them into 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-class particles in the coating, etc.

<Target area>
The applied 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 applied 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, the skin also includes nails that have hardened due to changes in the keratin of the epidermis of the skin.

<<Kit with a coating-type film-forming agent>>
The paint-type film-forming agent of the present disclosure can be provided as a kit having the above-mentioned first and second agents constituting the agent. In addition to the first and second agents, the kit may have optional components such as a component for facilitating application of the first agent, etc. to a target site, the various cosmetics described above, or the kit may be used in combination with optional components.

Optional components include, for example, an instruction manual, a spatula-shaped applicator, a brush, a cotton swab, a cutter, scissors, the various cosmetics mentioned above, a remover for removing the formed film from the target area, a mirror, etc. Here, "instructions for use" can include not only general instructions for use that are attached in the form of a document within the kit, but also instructions for use printed on, for example, the packaging container that contains the kit, or the packaging container such as a tube for injecting the first agent, etc.

In some embodiments, the kit may include, for example, the first and second agents packaged in separate containers or in separate compartments of a container having two or more compartments to prevent contact between the first and second agents. The packaged agents may be configured to be applied one at a time or to be mixed together before or during use.

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 remover as an integrated unit, i.e., including the remover in the kit, or using the kit and remover separately. For example, it is preferable to use a kit including a coat-type film-forming agent in combination with a separate remover, since it is possible to provide an optimal coat-type film-forming agent and remover for each individual.

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 by 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 a conventional sunscreen cosmetic is applied to the skin and then removed from the skin, it is necessary to wash it off with a detergent or the like. On the other hand, the film formed by the applied film-forming agent of the present disclosure does not require such a procedure, and the film exhibiting ultraviolet protection performance can be peeled off from the target site (e.g., skin) more easily.

In some embodiments, a suitable remover used to remove a film formed by the applied film-forming agent of the present disclosure contains at least one 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.

(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 can be used alone or in combination of two or more kinds.

The type of hydrocarbon oil is not particularly limited, and examples include liquid paraffin (mineral oil), olefin oligomers and their hydrogenated products (e.g., hydrogenated polydecene), and squalane.

The amount of hydrocarbon oil 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. There is no particular upper limit to the amount, and it 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.

(polar oil)
From the viewpoint of suitable removal of the film, 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 suitable removal of the film, 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 may be used alone or in combination of two or more kinds.

There are no particular limitations on the type of polar oil, and examples include ester oils. 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), tri(caprylic acid/capric acid)glyceryl (IOB value = 0.28), PPG-3 dipivalate (IOB value = 1.46), and octyl palmitate (IOB value = 0.13).

There is no particular limit to the amount of polar oil blended, and from the viewpoint of effectively removing the film, for example, 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 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 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 it is more preferable that silicone oil is not included in the composition constituting the remover.

How to use the remover
There is no particular limitation on the method of using the remover. In general, the remover can be applied to a part or the whole of the film formed on the target site, and then optionally rubbed. Then, the film can be removed by pulling the film that has peeled off from the target site with a finger or the like.

The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these. Unless otherwise specified, the blend amounts are shown in mass %. 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 be similarly applied to the above-mentioned forming agents and films formed by the forming agents.

Evaluation Test 1
The following tests were carried out using the test samples obtained by the manufacturing methods described below, and the results are shown in Table 2.

<Testing the effect of correcting concave defects>
Bioskin (a new age-specific cheek skin model, age group 30s, manufactured by Bealux Co., Ltd.), which is commercially available as a 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 where the eyes were about 30 cm away from the film surface and the line of sight was about 45 degrees to the film surface, and the correction effect of the recess defect was evaluated according to the following criteria. The results are shown in Tables 2 to 3. Here, A to C grades can be considered as passing, and D to E grades can be considered as failing. Note that in Comparative Examples 1 to 3, the correction effect of the recess defect was not tested because a film could not be formed:
A: No shadow was observed around the recessed defect (pore).
B: A very slight shadow was observed around the recessed defect (pore).
C: A slight shadow was observed around the recessed defect (pore).
D: Shadows were clearly observed around the recessed defects (pores).
E: Shadows were more clearly observed around the recessed defects (pores).

<Natural finish test>
Bioskin (a new age-specific cheek skin model, age group 30s, manufactured by Bealux Co., Ltd.), which is commercially available as a 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 where the eyes were about 30 cm away from the film surface and the line of sight was about 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, A to C grades can be considered as passing, and D to E grades can be considered as failing. Note that a natural finish test was not performed for Comparative Examples 1 to 3 because a film could not be formed, and Comparative Example 4 failed in the correction effect of the recess defect:
A: The finish was natural.
B: Almost (i.e. about 90%) natural finish.
C: The finish was generally (i.e. about 70%) natural.
D: The result was somewhat unnatural.
E: The result was unnatural.

<Film-forming property test>
The film formed on the artificial skin in the above correction test was touched with a finger to confirm whether a film was formed that would not peel off when touched with a finger. In the table, the case where such a film was formed is indicated as "passed", and the case where such a film was not formed is indicated as "failed".

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.

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-class particles having a refractive index of 2.0 or more in a paint-on film-forming agent was examined. The results are shown in Table 2. In the table, "Mw" refers to the weight average molecular weight. Furthermore, 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 off from the artificial skin five times using a high-precision digital micrometer (MDH-25MB, manufactured by Mitutoyo Corporation).

Comparative Example 1
(First Agent)
The first agent was prepared by uniformly mixing vinyl dimethicone (30.00 parts by mass) with a viscosity of 165,000 cst as the first unsaturated organopolysiloxane, volatile dimethicone (the remainder) as the oil component, hydrophobized pigment grade titanium oxide (0.05 parts by mass) as the pigment grade particles, and silylated silica (10.00 parts by mass) as the hydrophobized inorganic oxide particles. Note that this first agent did not contain any hydride-functionalized polysiloxane.

(Second Agent)
The ingredients in Table 1 were mixed uniformly to prepare the second agent 2-1.

Comparative Examples 2, 4, and 5, and Examples 1 to 4
Except for changing the components and their amounts in the first agent to those shown in Table 2, all the components were mixed at once and uniformly to prepare the first agent in the same manner as in Comparative Example 1. The second agent used was the same as in Comparative Example 1.

Comparative Example 3
Except for changing the components and their blending amounts in the first agent to those shown in Table 2, all the components were mixed at once and uniformly to prepare the first agent in the same manner as in Comparative Example 1. As the second agent, the second agent 2-2 containing no catalyst was used.

Example 5
Except for changing the components and their amounts in the first agent to those shown in Table 2, all the components were mixed at once and uniformly to prepare the first agent in the same manner as in Comparative Example 1. As the second agent, the second agent 2-3 containing pigment-grade particles was used.

<result>
As is clear from a comparison of the results of Comparative Examples 4 and 5 and Examples 1 to 4 in Table 2, when the pigment-class 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.

In addition, it was found that Example 5, which used a second agent containing pigment-class particles, had a better effect of correcting recess defects than Example 1, which used a second agent that did not contain pigment-class particles. This shows that the effect of correcting recess defects is improved when both the first and second agents contain pigment-class particles.

Test Example 2
Each test sample in this test example was prepared according to the following method. In this test example, the effect of the thickness of the coating was examined. The results are shown in Table 3.

Example 6: Coating thickness: 50 μm
Except for changing the components and their amounts in the first agent to those shown in Table 3, all the components were mixed at once and uniformly to prepare the first agent in the same manner as in Comparative Example 1. For the second agent, 2-1 in Table 1 was used.

Example 7: Coating thickness: 100 μm
Except for changing the components and their amounts in the first agent to those shown in Table 3, all the components were mixed at once and uniformly to prepare the first agent in the same manner as in Comparative Example 1. For the second agent, 2-1 in Table 1 was used.

<result>
As is clear from the results in Table 3, it was found that the effect of correcting the recess defects was improved as the thickness of the coating increased.

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.

<Evaluation of Appearance and Coating Color of Second Form (Evaluation of Powder Dispersibility)>
The second agent was stirred for 10 minutes at 7,000 rpm using a homomixer, and the appearance color immediately after stirring was visually confirmed. Next, the first agent (about 3 g) was applied to a black plate with a doctor blade to form a first agent layer, and the second agent (about 3 g) was applied to this first agent layer with a doctor blade, and the coating color of the resulting second agent layer was visually confirmed. If the appearance color and coating color were both approximately uniform and approximately matched to each other, it was evaluated as "passed", and if not, it was evaluated as "failed". In this test, the focus was on the appearance color and coating color of the second agent, so no catalyst was added to the second agent.

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 weight of vinyl dimethicone as the first unsaturated organopolysiloxane and 10 parts by weight of hydrogen dimethicone as the first hydride-functionalized polysiloxane.

<Second Agent>
The ingredients in Table 4 were mixed uniformly to prepare the second formulations.

<result>
The second agent of Reference Comparative Example 1, which does not contain a silicone surfactant, was inferior in powder dispersibility, and both the appearance color and the application color were uneven. On the other hand, the second agents of Reference Examples 1 to 3, which contain a silicone surfactant, and the second agents of Reference Examples 4 to 6, which have a higher powder ratio than the second agents, all have excellent powder dispersibility and do not cause unevenness in both the appearance color and the application color, and were evaluated as passing the test. Note that although Reference Examples 1 to 3 are all passing the test, it was confirmed that the performance is best in the order of PEG/PPG-19/19 dimethicone, carboxydecyl trisiloxane, and bis-butyl dimethicone polyglyceryl-3, that is, bis-butyl dimethicone polyglyceryl-3 is the best in terms of performance.

The results of Reference Comparative Examples 2 to 6 confirmed that no effect was obtained with surfactants and dispersants other than silicone-based surfactants.

Furthermore, the results of Reference Comparative Examples 7 to 11 confirmed that even if the powder ratio was reduced, no effect was obtained with surfactants and dispersants other than silicone-based surfactants.
