Description

[Technical Field]

[0001] This invention relates to an overcoat cosmetic. [Background technology]

[0002] Consumers have a need to prevent makeup from smudging or breaking down due to sweat, sebum, friction with clothing, and facial movements after applying makeup.

[0003] For example, Patent Document 1 discloses a skin cosmetic that can provide moisture to the skin, particularly in the form of a lotion or cream, without causing foundation to crease even when applied over a face with makeup, and that also has excellent moisturizing properties over time and long-term formulation stability.

[0004] Furthermore, Patent Document 2 proposes a water-based or oil-in-water mist cosmetic characterized by (A) containing a specific water-soluble thickener and being filled into a pump-type spray container with a diameter of Φ0.25 to Φ0.55.

[0005] Furthermore, Patent Document 3 proposes, as claim 1, a multi-layered makeup protective cosmetic composition containing components (A) to (C): (A) an oil-soluble film-forming agent, (B) 40 to 95% by mass of water, and (C) a volatile oil, which is used by spraying it onto makeup.

[0007] The inventor of the present invention has noted that in an overcoat cosmetic containing a film-forming agent, for example, when the film-forming agent is blended in a multi-layer type mist, while the makeup durability is enhanced, the volatile components volatilize at the mouth part of the pump and the resin precipitates, which tends to cause clogging. Also, while the conventional overcoat cosmetics have the main function of a makeup durability effect, the inventor has noted that sufficient consideration has not been given to improving the finish and usability, which are important in makeup cosmetics, particularly imparting gloss and a moisturizing feeling.

[0008] Therefore, an object of the present invention is to provide an overcoat cosmetic excellent in makeup durability effect, resistance to clogging, glossiness, and moisturizing feeling.

Means for Solving the Problems

[0009] As a result of intensive studies, the inventor of the present invention has found that by containing a specific polyorganosiloxane and a volatile hydrocarbon oil, it is excellent in the makeup durability effect, which is a basic function of the overcoat cosmetic, while being less likely to clog the injection port or injection nozzle over time, and further, an overcoat cosmetic capable of imparting gloss to the makeup film and excellent in the moisturizing feeling of the makeup film can be obtained, and the present invention has been completed.

[0010] That is, the present invention is 〔1〕 The following components (A) and (B); (A) A polyorganosiloxane having a block structure represented by the following general formula (1), having a weight average molecular weight of 500,000 or more, having a solid property at room temperature in a solvent-free state, and having a softening point of 50°C or more

Chemical formula

[0011] According to the present invention, it is possible to provide an overcoat cosmetic which is excellent in the makeup retention effect which is a basic function of the overcoat cosmetic, is less likely to clog the injection port or injection nozzle over time, can impart gloss to the makeup film, and is excellent in the moisturizing feeling of the makeup film.) [Embodiment for Carrying Out the Invention]

[0012] A preferred embodiment of the present invention will be described in detail. However, the present invention is not limited to the following preferred embodiments and can be freely changed within the scope of the present invention. In the present specification, percentages are expressed by mass unless otherwise specified. In the present specification, "~" means a range including the numerical values before and after it.

[0013] Component (A) used in the present invention is a novel film-forming resin, which is represented by the following formula (1), has a weight average molecular weight of 500,000 or more, and has a block structure characterized in that its property at room temperature in a solvent-free state is solid and its softening point is 50°C or more. It is a polyorganosiloxane (hereinafter also referred to as "polyorganosiloxane having a block structure").

[0014] [Chemical formula]

[0015] In the formula, R 1 , R 2 , R 3 , R 4 , R 5 is a hydrogen atom or a saturated or unsaturated hydrocarbon group having 1 to 20 carbon atoms which may have a substituent, m represents the repeating number of diorganosiloxy units, 50 ≥ m ≥ 0, a, b, c, d, e represent the existing molar ratios of their respective siloxane units, 0.3 ≥ a ≥ 0, 0.3 ≥ b > 0, 0.5 ≥ c ≥ 0, 0.95 ≥ d > 0.5, 0.3 ≥ e ≥ 0, a + b×(2 + m) + c + d + e = 1, x, y are the numbers of hydroxy groups or alkoxy groups bonded to 1 mole of Si atoms of the siloxane units of a to e above, and 0.1 ≥ x > 0, 0.1 ≥ y > 0 are represented.

[0016] R 1 , R 2 , R 3 , R 4 , R 5Each of these is a saturated or unsaturated hydrocarbon group having 1 to 20 carbon atoms, which may independently have a hydrogen atom or a substituent, and preferably a saturated or unsaturated hydrocarbon group having 1 to 10 carbon atoms. Specific examples include methyl group, chloromethyl group, methoxymethyl group, ethyl group, ethoxyethyl group, vinyl group, propyl group, (meth)acryloxypropyl group, mercaptopropyl group, chloropropyl group, glycidyloxypropyl group, epoxycyclohexylethyl group, allyl group, butyl group, pentyl group, cyclopentyl group, hexyl group, hexenyl group, cyclohexyl group, phenyl group, heptyl group, octyl group, octylenyl group, (meth)acryloxyoctyl group, mercaptooctyl group, chloroctyl group, glycidyloxyoctyl group, decyl group, etc., but among these, R 1 , R 2 , R 3 , R 4 For this, methyl groups, ethyl groups, propyl groups, and phenyl groups are preferred, methyl groups and ethyl groups are more preferred, and methyl groups are even more preferred. 5 For this group, saturated hydrocarbon groups having 1 to 4 carbon atoms are preferred, with examples including methyl, ethyl, n-propyl, i-propyl, n-butyl, s-butyl, i-butyl, and t-butyl groups, and more preferably n-butyl, s-butyl, and i-butyl groups.

[0017] a, b, c, d, and e represent the molar ratios of each siloxane unit, with 0.3≧a≧0, 0.3≧b>0, 0.5≧c≧0, 0.95≧d>0.5, 0.3≧e≧0, and a+b×(2+m)+c+d+e=1. x and y represent the number of hydroxyl groups or alkoxy groups bonded to 1 mole of Si atoms in the siloxane units a-e, with 0.1≧x>0 and 0.1≧y>0.

[0018] Regarding the hydroxyl or alkoxy groups bonded to the Si atoms of a polydiorganosiloxane having a block structure, it is preferable from the viewpoint of polymer stability that x and y are 0.05≧x>0 and 0.05≧y>0, respectively. When x=y=0, it means that there are no structural groups that undergo dehydration, dealcoholization, condensation, and crosslinking. Although the polymer stability is excellent, it becomes a component that does not cure, which is undesirable as it reduces the durability of the coating film. On the other hand, when x or y is greater than 0.1, while the aforementioned curability is excellent, there is a high possibility that the polymer stability will decrease, and in particular when x>0.1, the stability will be low, which is undesirable.

[0019] Regarding the ratio of siloxane units in the polydiorganosiloxane having the block structure of the present invention, from the viewpoint of polymer stability, high degree of polymerization, and film flexibility, it is preferable that 40>m>10, 0.1≧a>0, 0.3≧b>0, 0.3≧c>0, and 0.05≧e≧0. Furthermore, in addition to the above, it is even more preferable that 0.9≧d>0.7.

[0020] The polydiorganosiloxane having a block structure has a weight-average molecular weight of 500,000 or more, preferably 1,000,000 or more, and more preferably 2,000,000 or more, from the viewpoint of film-forming properties, film continuity, and lack of stickiness of the coating film. There is no particular upper limit to the weight-average molecular weight, but from the viewpoint of suppressing gelation, for example, a weight-average molecular weight of 16,000,000 or less is preferred, more preferably 10,000,000 or less, and still preferred to be 8,000,000 or less. As a range that balances the performance of the coating film and the stability of the siloxane polymer, 500,000 to 16,000,000 is preferred, 1,000,000 to 10,000,000 is more preferred, and still preferred to be 2,000,000 to 8,000,000.

[0021] The weight-average molecular weight in this invention is a value obtained by converting a polystyrene with a known molecular weight into a standard substance using gel permeation chromatography (GPC) measured under the conditions shown below. [Measurement conditions] Flow rate: 0.5mL / min Detector: Differential refractive index detector (RI) Columns: Use two of the following columns directly connected together. TSKgel GMHHR-H(30) (7.8mm I.D. × 30cm × 1) (Manufactured by Tosoh Corporation) Column temperature: 40℃ Sample injection volume: 200 μL (THF solution with a concentration of 20 g / L)

[0022] Polydiorganosiloxanes with a block structure are preferably introduced with a linear polydiorganosiloxane structure from the viewpoint of non-stickiness of the coating film and film flexibility. As an indicator of the state in which such a structure is introduced while being maintained 29 One method is signal analysis by Si-NMR, specifically, it is possible to distinguish by detecting signals attributed to polydiorganosiloxanes that fall within a predetermined range of chemical shifts. Generally, they are detected in the range of -10 to -50 ppm, but the polydiorganosiloxanes having a block structure contained in the cosmetic composition of the present invention are 29 The Si-NMR spectrum is characterized by the detection of a chemical shift of the signal attributed to the diorganosiloxane unit in the range of -15 to -25 ppm, and the detection width of the signal peak (the difference between the chemical shift at the detection start point and the chemical shift at the detection end point) being 3 to 7 ppm. The narrower the detection width of the signal peak, the more it indicates that the linear siloxane structure is maintained while being introduced into the polymer. If the detection width is greater than 10 ppm, it means that the linear structure is practically absent from the polymer, making it difficult to obtain the desired coating properties. In the present invention, 29 Si-NMR was performed using a 300MHz-NMR spectrometer manufactured by JEOL Ltd., and a solution sample with a sample concentration of 20 wt% was measured under conditions of 25°C.

[0023] The composition obtained by dissolving the block structure polyorganosiloxane of the present invention in an organic solvent is characterized by the extract water having an acidic pH of 3.5 to 6. Generally, it is known that the pH of the extract water obtained by dissolving polyorganosiloxane in an organic solvent is neutral unless the solvent itself is acidic or basic. By controlling the pH within the aforementioned range, it is possible to obtain a stable solution without causing gelation or other problems over a long period of time, even with high molecular weight polyorganosiloxanes like those of the present invention. Methods for controlling the extract water pH include the use of acids and buffers, but preferably, an acid is used, and more preferably, an organic carboxylic acid is used.

[0024] Examples of acids include inorganic acids such as hydrochloric acid, nitric acid, and sulfuric acid, as well as organic carboxylic acids such as formic acid, acetic acid, propionic acid, citric acid, succinic acid, maleic acid, methanesulfonic acid, and trifluoromethanesulfonic acid, but are not limited to those exemplified here.

[0025] In compositions in which the polyorganosiloxane having the block structure of the present invention is dissolved in an organic solvent, it is preferable that the organic solvent is not an aromatic hydrocarbon. This is because aromatic hydrocarbons, such as benzene, toluene, and xylene, are organic solvents with a high environmental impact.

[0026] The polyorganosiloxane having a block structure contained in the cosmetic composition of the present invention can be produced, for example, by the following steps 1 to 3. Step 1: Silane monomers capable of constituting the siloxane unit of formula (1) above, having a chlorosilyl group or an alkoxysilyl group having 1-2 carbon atoms as a hydrolyzable group, and polydiorgannosiloxanes having hydrolyzable silyl groups at both ends are added dropwise to a mixed medium layer consisting of water, a hydrophilic organic solvent with a water solubility of 50-1000 g / L at 25°C, and a hydrophobic organic solvent with a water solubility of 1 g / L or less at 25°C, and undergo hydrolysis and condensation. Step 2: After removing the generated hydrogen chloride and alcohol, condensation polymerization is carried out under strongly acidic conditions with a pH of 3 or less until the weight-average molecular weight reaches 500,000 or more. Step 3: Neutralize or remove the acid and adjust the pH of the extracted water to 3.5-6.

[0027] Examples of hydrophilic organic solvents with a water solubility of 50 to 1000 g / L at 25°C include alcohols, ketones, esters, and ether compounds. Specifically, examples include n-propanol, isopropanol, n-butanol, secondary butanol, isobutanol, tertiary butanol, propylene glycol monomethyl ether, propylene glycol monomethyl ether acetate, ethyl acetate, butyl acetate, methyl ethyl ketone, and cyclohexanone. Among these, n-propanol, isopropanol, n-butanol, and isobutanol are preferred from the viewpoint of controlling the reaction during hydrolysis condensation and suppressing the formation of insoluble substances.

[0028] Examples of hydrophobic organic solvents with a water solubility of 1 g / L or less at 25°C include aliphatic hydrocarbon solvents such as hexane, heptane, octane, cyclohexane, methylcyclohexane, ethylcyclohexane, decane, isododecane, and isoparaffin compounds derived from olefin gases, as well as aromatic hydrocarbon solvents such as toluene and xylene. Among these, hexane, heptane, octane, cyclohexane, methylcyclohexane, and ethylcyclohexane are preferred from the viewpoint of reaction control during hydrolysis condensation, maintenance of block structure, and solubility of the resulting resin, and hexane, heptane, and ethylcyclohexane are more preferred.

[0029] The preferred weight ratio of a mixed medium consisting of water, a hydrophilic organic solvent with a water solubility of 50 to 1000 g / L at 25°C, and a hydrophobic organic solvent with a water solubility of 1 g / L or less at 25°C is 10 to 30 parts hydrophilic organic solvent and 10 to 30 parts hydrophobic organic solvent, with water being 100 parts. Exceeding this upper limit will reduce productivity because it will require using more organic solvent than necessary. On the other hand, if it falls below this lower limit, it will be difficult to control the reaction during hydrolysis condensation, and solvent-insoluble substances will be generated.

[0030] As the silane and siloxane materials to be hydrolyzed and condensed, it is preferable to use silane monomers that can constitute the siloxane unit of formula (1) having a chlorosilyl group or an alkoxysilyl group having 1 to 2 carbon atoms as a hydrolyzable group, and polydiorganosiloxanes having hydrolyzable silyl groups at both ends. In particular, for polydiorganosiloxanes having hydrolyzable silyl groups at both ends, α,ω-dimethylchlorosiloxypolydimethylsiloxane, shown in formula (2) below, is preferred from the viewpoint of reactivity during hydrolysis. Furthermore, regarding the silane monomer, it is more preferable from the viewpoint of reaction control and production efficiency that the compound has only a chlorosilyl group as a hydrolyzable group.

[0031] [ka] (In the equation, 50 ≥ m ≥ 0.)

[0032] During the hydrolysis condensation reaction, the weight concentration of the reactive silane and siloxane material is preferably 10-30% by weight relative to the total amount of the mixed medium including water and the reactive silane and siloxane material. Exceeding this upper limit makes it difficult to control the reaction during hydrolysis condensation, and solvent-insoluble substances are generated. On the other hand, below this lower limit is undesirable because it requires the use of more organic solvent than necessary, resulting in reduced productivity.

[0033] The temperature during the hydrolysis condensation reaction is preferably between 0 and 40°C. If the temperature is higher than 40°C, it becomes difficult to control the reaction during hydrolysis condensation, and there is a risk of generating solvent-insoluble substances. If the temperature is below 0°C, the aforementioned reaction control effect becomes excessive, and it becomes inefficient in terms of the cooling energy required for temperature control.

[0034] In a method for producing polyorganosiloxanes having a block structure, after removing the generated hydrogen chloride and alcohol, condensation polymerization is carried out under strongly acidic conditions with a pH of 3 or less until the weight-average molecular weight reaches 500,000 or more. From the viewpoint of reaction control, the reaction temperature is preferably in the range of 10 to 80°C. Furthermore, from the viewpoint of reaction control, the pH is preferably in the range of 1 to 3. If the reaction temperature is higher than the upper limit of the range and the pH is lower than the lower limit of the range, the condensation polymerization proceeds excessively quickly and becomes difficult to control. On the other hand, if the reaction temperature is lower than the lower limit of the range and the pH is higher than the upper limit, the polymerization rate decreases significantly, and productivity deteriorates.

[0035] The content of component (A) in the present invention is not particularly limited, but is preferably 0.05% by mass (hereinafter simply abbreviated as %) or more, more preferably 0.1% or more, and even more preferably 0.5% or more, as solid content relative to the total amount of the overcoat cosmetic. Also, 10% or less is preferred, 8% or less is more preferred, and 5% or less is even more preferred. Furthermore, 0.05 to 10% is preferred, 0.1 to 8% is more preferred, and 0.5 to 5% is even more preferred. Within this range, it is more preferable because it provides superior cosmetic durability, resistance to clogging, and glossiness.

[0036] The volatile hydrocarbon oil component (B) used in the present invention is volatile at 1 atmosphere and 25°C and is also used as a solvent for component (A). There are no particular restrictions as long as it can be used in cosmetics, but it is preferable to use a volatile hydrocarbon oil with a boiling point of 240°C or lower. For example, in the case of volatile hydrocarbon oils, examples include side-chain hydrocarbons such as isooctane, isododecane, isohexadecane, and isoeicosaene; straight-chain hydrocarbons such as decane, undecane, dodecane, tridecane, and (C9-12) alkanes; isoparaffins or mixtures thereof; and light liquid isoparaffins obtained by polymerizing or copolymerizing (a degree of polymerization of 4 to 6 is preferable) isobutene, n-butene, etc., and then hydrogenating them.

Examples include decamethylcyclopentasiloxane, octamethylcyclotetrasiloxane, methyl trimethicone, and low molecular weight dimethylpolysiloxane, which can be used individually or in combination of two or more as needed. Commercially available products include TMF-1.5, KF-995, KF-96L-1cs, KF-96L-1.5cs, KF-96L-2cs (manufactured by Shin-Etsu Chemical Co., Ltd.), and BELSIL DM 1PLUS (manufactured by Asahi Kasei Wacker Silicone Co., Ltd.). Furthermore, from the viewpoint of resistance to clogging, decamethylcyclopentasiloxane and low molecular weight dimethylpolysiloxane are preferred, with low molecular weight dimethylpolysiloxane having a viscosity of 3 mm at 25°C. 2 (less than / s) is even more preferable.

[0039] The content of component (C) in the present invention is not particularly limited, but is preferably 0.2% or more, more preferably 0.8% or more, and even more preferably 8% or more, relative to the total amount of the overcoat cosmetic. Also, is preferably 25% or less, more preferably 20% or less, and even more preferably 17% or less. Furthermore, is preferably 0.2 to 25%, more preferably 0.8 to 20%, and even more preferably 8 to 17%. Within this range, it is more preferable because it is less prone to clogging.

[0040] In the present invention, the mass ratio (B) / (A) of component (B) to component (A) is not particularly limited, but its preferred lower limit is preferably 0.002 or more, more preferably 0.04 or more, and even more preferably 0.4 or more, and its preferred upper limit is preferably 500 or less, more preferably 250 or less, and even more preferably 5 or less. This makes it possible to obtain an overcoat cosmetic composition with excellent makeup-lasting effect and resistance to clogging. Furthermore, a preferred numerical range for the mass ratio (B) / (A) of component (B) to component (A) is preferably 0.002 to 500, more preferably 0.04 to 250, and even more preferably 0.4 to 5, based on the total mass of the overcoat cosmetic. By setting the ratio within this range, an overcoat cosmetic with excellent makeup retention and resistance to clogging can be obtained.

This makes it possible to create emulsified cosmetics and multi-layered cosmetics, and to improve the moisturizing effect.

[0042] The content of component (D) in the present invention is not particularly limited, but is preferably 0.01% or more, more preferably 1% or more, and even more preferably 5% or more, relative to the total amount of the overcoat cosmetic. Also, 95% or less is preferred, more preferably 85% or less, and even more preferably 75% or less. Furthermore, 0.01 to 95% is preferred, more preferably 1 to 85%, and even more preferably 5 to 75%.

For example, components (A) to (B) and other components can be filled into a container (e.g., a dispenser container, a spray nozzle container, a spray container, a finger spray container, a pressurized spray container, a mist spray container, etc.) to obtain the product. Alternatively, in the case of an emulsion, components (A) to (B) and other oily components can be mixed, then an aqueous component can be added to emulsify, and then the mixture can be filled into a container to obtain an oil-in-water emulsion type overcoat cosmetic. The components used in the present invention may also be mixed before filling. Furthermore, the components used in the present invention may be filled into multiple containers, such as a water layer container, an oil layer container, and a powder container, to produce a multi-component product (kit), such as a two-component or three-component type. In the case of a multi-component product, the user can mix the water layer component, oil layer component, powder component, etc., in desired proportions before spraying.

[0055] The uses of the overcoat cosmetic of the present invention are not particularly limited, but it is preferable to use it as a protective agent for makeup or to add gloss to makeup by spraying it onto the face after applying base makeup such as foundation, or makeup such as eyeshadow and blush. It can be used in a container with a spray nozzle or in aerosol form. A spray container with a spray nozzle diameter of approximately φ0.1 to 0.6 mm (preferably φ0.2 to 0.5 mm) may be used. Since it is used by spraying, it is preferable that it be a liquid cosmetic.

[0056] The dosage form of the overcoat cosmetic of the present invention is not particularly limited, but examples include oil-based, oil-in-water emulsion, and multilayer types. A multilayer type is a multilayer type with at least two layers, including an oil layer on top and a water layer below, as shown in the [Examples] below, and can be made into three or more layers by including powders or using oil layers with different specific gravities. In the case of a multilayer type, mixing immediately before spraying allows for good dispersion and this dispersed state can be maintained for a certain period, while leaving it for a certain period will cause it to revert to a multilayer type. As the overcoat cosmetic of the present invention, a multilayer type is preferred from the viewpoint of cosmetic longevity, resistance to clogging, and moisturizing effect.

[0057] Furthermore, the viscosity (mPa·s) of the overcoat cosmetic composition of the present invention is preferably 1500 mPa·s or less, measured at 25°C using a B-type viscometer, rotor No. 2, 6 rpm, and an average value over 1 minute. It is even more preferable if the viscosity is 1000 mPa·s or less, as this provides excellent resistance to clogging.

[0058] Furthermore, the present invention can also take the following configuration. [1] The following components (A), (B); (A) A polyorganosiloxane having a block structure, represented by the following general formula (1), having a weight-average molecular weight of 500,000 or more, and being a solid at room temperature in the absence of solvent with a softening point of 50°C or higher.

[0059] The present invention will be described in more detail below with reference to examples and comparative examples, but the present invention is not limited to the following examples. In these examples, unless otherwise specified, "parts" and "%" mean "parts by mass" and "% by mass," respectively. The apparatus used in the examples is as follows.

[0060] (1) GPC measurement conditions Equipment: HLC-8320GPC manufactured by Tosoh Corporation Developing solvent: Tetrahydrofuran (THF) Flow rate: 0.5mL / min Detector: Differential refractive index detector (RI) Columns: Use two of the following columns directly connected together. TSKgel GMHHR-H(30)(7.8mmI.D.×30cm×1) (Manufactured by Tosoh Corporation) Column temperature: 40℃ Sample injection volume: 200 μL (THF solution with a concentration of 20 g / L) Standard: Monodisperse polystyrene (2) Measurement conditions for silicon nuclear magnetic resonance spectroscopy (29Si-NMR) Equipment: 300MHz-NMR manufactured by JEOL Ltd. Solvent: CDCl3 Sample concentration: 20% Internal standard: Tetramethylsilane (TMS)

[0061] In the following, the kinematic viscosity of the product was measured at 25°C using a Cannon-Fenske viscometer according to the method described in JIS Z 8803:2011. The content of silanol hydroxyl groups in the product (mass%), hereinafter referred to as silanol content, was quantified from the amount of methane gas generated when the product was reacted with a Grignard reagent (methylmagnesium iodide).

[0062] Manufacturing Example 1 [Synthesis of polyorganosiloxanes with block structures] 2700 g of deionized water, 400 g of isobutanol, and 300 g of heptane were charged into a 5 L three-necked flask equipped with a stirrer, condenser, dropping funnel, and thermometer, and stirred. A mixture of 650 g (4.3 mol) of methyltrichlorosilane (at 25°C), 70 g (0.9 mol Si equivalent) of α,ω-dimethylchlorosiloxypolydimethylsiloxane (formula 3 below), and 300 g of heptane was added dropwise over 2 hours while controlling the internal temperature to prevent it from exceeding 40°C. After the addition was complete, the aqueous hydrochloric acid phase, in which hydrogen chloride generated by the hydrolysis of the chlorosilyl group dissolved in the deionized water, was separated from the organic phase. This organic phase was washed multiple times with saline solution until the water-wash phase became neutral. The resulting organic phase had a kinematic viscosity of 2.7 mm². 2 The organic solution contained an organosiloxane with a molecular weight of approximately 7600, measured by GPC, and had a non-volatile residue of 33% under drying conditions of 105°C for 3 hours. 20 g of concentrated hydrochloric acid was added to this organic solution, and a condensation polymerization reaction was carried out by heating at 60°C for 3 hours. Subsequently, heptane was added to adjust the concentration to a drying residue of 20%. After washing multiple times with saline solution until the water washing phase was neutral, 0.03% citric acid was added to the organic solution and dissolved to obtain an organic solution in which the polyorganosiloxane with the desired block structure was dissolved in an organic solvent. This organic solution had a kinematic viscosity of 14.4 mm². 2 Under drying conditions of / s at 105°C for 3 hours, the non-volatile residue was 21%, and the molecular weight was approximately 1.43 million according to GPC. 29 Si-NMR measurements revealed signals attributed to diorganosiloxane units (D units) in the range of -16 to -23 ppm, with a detection width of 5 ppm for the main signal peak. Furthermore, it was confirmed that the polyorganosiloxane having the block structure described above is solid at room temperature in the absence of solvent, and that its softening point is 50°C or higher. It was also confirmed that the polyorganosiloxane having the block structure described above satisfies the above general formula (1).

[0063] [ka]

[0064] Manufacturing Example 2 [Synthesis of polyorganosiloxanes with block structures] Polyorganosiloxane 2, having a block structure and a weight-average molecular weight of 3.1 million, was obtained in the same manner as in Production Example 1, except that the condensation polymerization reaction conditions were changed to 60°C for 4 hours. Furthermore, it was confirmed that the polyorganosiloxane having the block structure described above is solid at room temperature in the absence of solvent, and that its softening point is 50°C or higher. It was also confirmed that the polyorganosiloxane having the block structure described above satisfies the above general formula (1).

[0065] Manufacturing Example 3 [Synthesis of polyorganosiloxanes with block structures] Polyorganosiloxane 3, having a block structure and a weight-average molecular weight of 590,000, was obtained in the same manner as in Production Example 1, except that the condensation polymerization reaction conditions were changed to 60°C for 2 hours.

[0066] Manufacturing Example 4 To 500 g of the 20% dried residue polysiloxane solution obtained in Production Example 1, 16 g (0.16 mol) of triethylamine and 13 g (0.12 mol) of trimethylchlorosilane were added, and the mixture was heated at 60°C for 3 hours to carry out the trimethylsiloxylation reaction of the silanol in the polysiloxane. Subsequently, the mixture was washed multiple times with saline solution until the water washing phase became neutral, yielding an organic solution in which a polyorganosiloxane with a weight-average molecular weight of 1.56 million and a trimethylsiloxy-bound and block structure was dissolved in an organic solvent. Furthermore, it was confirmed that the polyorganosiloxane having the block structure described above is solid at room temperature in the absence of solvent, and that its softening point is 50°C or higher. It was also confirmed that the polyorganosiloxane having the block structure described above satisfies the above general formula (1).

[0067] Examples 1-12 and Comparative Examples 1-4: Multilayer overcoat cosmetics Multilayer overcoat cosmetics with the formulations shown in Table 1 below were prepared using the manufacturing method described below, and evaluated for a. makeup longevity, b. resistance to clogging, c. glossiness, and d. moisturizing effect using the evaluation method described below. The results are also shown in Table 1.

[0068] [Table 1]

[0069] *1: SILFORM FLEXIBLE RESIN (manufactured by Momentive Performance Materials Japan) *2: SR1000 (manufactured by Momentive Performance Materials Japan) *3: DOWSIL TM FC 5002 IDD Resin Gum (manufactured by Dow-Toray)

[0070] (Manufacturing method) (A) Oil layer: Mix and dissolve components (1) to (13) uniformly. (B) Aqueous layer: Mix and dissolve components (14) to (16) uniformly. (C) A container with a push-type spray nozzle (spray nozzle diameter φ0.3 mm: non-aerosol container) was filled in the order of (B) aqueous layer and (A) oil layer to obtain a multi-layered overcoat cosmetic. Alternatively, a multi-layered overcoat cosmetic can be obtained by filling a container with a spray nozzle with the mixed and dissolved (1) to (13) and (14) to (16) in any order and shaking it vigorously.

[0071] (Evaluation method) A panel of 10 cosmetic evaluation specialists sprayed each multi-layered overcoat cosmetic product 10 times onto the entire face, which had foundation and eye makeup applied. They then evaluated the following five-point scale according to the evaluation criteria below: (a) makeup longevity, (b) resistance to clogging, (c) shine, and (d) moisturizing effect. For items (c) and (d), the makeup longevity was evaluated immediately after use and 8 hours later. For item (a), the makeup longevity was evaluated 8 hours after use while the user went about their normal daily life. For item (b), the amount sprayed at the start of use and the amount sprayed at the end of use were compared. Subsequently, the average score of all panel members was calculated and judged according to the judgment criteria below.

[0072] (i) Makeup staying power: Check whether the makeup has not smudged or deteriorated after 8 hours of application. (Rating): (Evaluation Result) 4 points: No makeup breakdown was observed 8 hours after application. 3 points: Almost no makeup breakdown was observed 8 hours after application. Points 2: Some makeup breakdown was observed 8 hours after application. 1 point: Makeup breakdown was observed 8 hours after application. 0 points: Makeup breakdown is very noticeable 8 hours after application.

[0073] (b) Resistance to clogging: The test product, stored at 5°C, is dispensed 5 times daily. The average volume dispensed by 5 pushes after 30 days should be the following ratio to the average volume dispensed by 5 pushes at the start of the test (N=3 average). (Rating): (Evaluation Result) 4 points: 95% or higher 3 points: Less than 95% to 80% or more 2 points: Less than 80% to 65% or more 1 point: Less than 65% to 50% or more 0 points: Less than 50%

[0074] Specifically, the composition to be used in the test is filled into three spray nozzle-equipped containers, and three identical spray nozzle-equipped containers are prepared. These are stored at 5°C for 10 to 12 hours. After storage, the amount (mg) sprayed into a beaker after 5 pushes is measured for each container at 5°C. The total amount using the three containers is calculated, and from this total amount, the average amount (mg) sprayed per container at the start of the test (day 1) is calculated. After the start of the test, these three containers are continued to be stored at 5°C, and the spray is dispensed 5 times daily at 5°C. Day 30 is the end day, and the amount (mg) sprayed into a beaker after 5 pushes is measured at the end of day 30. The average amount (mg) sprayed per container at the end of the test (day 30) is calculated in the same way as at the start of the test (N=3 average). Then, the ratio of the average discharge mass from 5 pushes at the end of the test to the average discharge mass from 5 pushes at the start of the test (i.e., [average discharge mass per container at the end of the test / average discharge mass per container at the start of the test] × 100 (%)) is calculated, and the score that falls within the range (percentage) of the evaluation results below becomes the evaluation score for the composition used in the test. The less clogging of the spray nozzle or nozzle caused by the composition used, the smaller the difference between the discharge mass at the end of the test and the discharge mass at the start of the test, and the closer the evaluation result approaches 100%.

[0075] (h) Shine: Whether you feel a shine immediately after application to the skin and 8 hours after application. (Rating): (Evaluation Result) 4 points: Noticeable shine compared to before application, and maintained even after 8 hours. 3 points: It feels shinier than before application, and although it decreases slightly after 8 hours, it maintains a level of shine higher than when untreated. Points 2: While the shine is noticeable compared to before application, the shine decreases to the same level as before application after 8 hours. 1 point: The gloss level is the same as before application, and it maintains the same level of gloss even after 8 hours. 0 points: The gloss level remains unchanged compared to before application, but decreases after 8 hours.

[0076] (ii) Moisturizing sensation: Whether you feel a moisturizing sensation immediately after application to the skin and 8 hours after application. (Rating): (Evaluation Result) 4 points: I felt more moisturized than before application, and the effect lasted for 8 hours. 3 points: It feels more moisturizing than before application, and although it decreases slightly after 8 hours, it maintains a level of moisturizing that is higher than when not applied. Points 2: While it feels more moisturizing than before application, the shine decreases to the same level as before application after 8 hours. 1 point: The moisturizing effect is the same as before application, and the same level of moisturizing effect is maintained even after 8 hours. 0 points: Moisture level remains unchanged compared to before application, and decreases after 8 hours.

[0077] [Judgment criteria] (Average score): (Judgment) 3.5 points or more: A (excellent) 2.5 points or higher but less than 3.5 points: B (Good) 1.5 points or more but less than 2.5 points: C (Somewhat unacceptable) Less than 1.5 points: D (Not acceptable)

[0078] As is clear from the results in Table 1, the multilayer overcoat cosmetics of Examples 1 to 12 of the present invention were superior to Comparative Examples 1 to 4 in terms of makeup retention, resistance to clogging, glossiness, and moisturizing effect. On the other hand, in Comparative Examples 1 to 3, which contained other silicone-based resins instead of component (A), satisfactory results were not obtained in terms of resistance to clogging, glossiness, and moisturizing properties. Furthermore, in Comparative Example 4, which contained a non-volatile silicone oil instead of component (B), the makeup-lasting effect was lacking, and satisfactory results were not obtained.

[0079] The following describes examples of overcoat cosmetics. After drying the solution from Production Example 4 with a spray dryer to obtain a solid, a solution prepared by dissolving 30% of the solid in 70% isododecane is used as DT resin (30% ISD solution).
