Description

Oil-based cosmetics

[0001] The present invention relates to an oily cosmetic preparation.

[0002] Oil-based cosmetics are widely used in makeup cosmetics such as lipstick, foundation, concealer, eyeliner, eye shadow, and blush. In recent years, diversifying market trends have led to a wide variety of consumer demands for cosmetic film finishes and usability, with a particular preference for a natural finish that reduces the visibility of wrinkles and unevenness on the skin. Various studies have been conducted to achieve a finish that reduces the visibility of wrinkles and unevenness on the skin. While a known technique for reducing the visibility of wrinkles and unevenness on the skin involves incorporating a large amount of powder containing a coloring pigment, this technique can sometimes result in poor makeup wear, a lack of moisturizing sensation, and difficulty in achieving the dispersibility of the coloring pigment. Alternatively, the cosmetic may exhibit a glossy finish due to the oil immediately after application, but after a while the cosmetic film becomes matte, reducing the visibility of wrinkles and unevenness on the skin. Therefore, various techniques have been developed to impart this effect to cosmetics that reduce the visibility of wrinkles and unevenness on the skin. For example, a technology has been proposed for a composition having an excellent soft focus effect, which is an anhydrous composition comprising a specific amount of a lipophilic gelling agent, specific amounts of a filler including a first filler and a second filler different from the first filler, and a fatty phase, wherein the first filler and the second filler are selected from spherical cellulose particles, powder of an N-acylamino acid having a C8 to C22 acyl group, polyamide particles, and spherical porous silica particles (see Patent Document 1). Furthermore, a liquid lip cosmetic has been proposed (see Patent Document 2), which is light and soft to the touch upon application, easily outlines the lips, provides a high level of moisturizing, and reduces the appearance of vertical lip wrinkles, all of which last for a long time, by combining a specific amount of paste oil having a melting point of 30°C or higher but lower than 61°C, an oil component that is liquid at 25°C, specific amounts of plate-like powder and spherical powder, a color pigment, and a pearl pigment. Meanwhile, technologies for improving the long-lasting effect of oil-based cosmetics have been investigated. For example, Patent Document 3 describes that by including a crosslinked organosilicon resin, it is possible to improve the spreadability upon application, stickiness, uneven color finish, and makeup longevity of oil-based cosmetics such as lipstick and oil-based mascara.

[0004] However, while the technology of Patent Document 1 has the effect of making wrinkles and unevenness on the skin less noticeable, the cosmetic that has penetrated into the wrinkles and unevenness of the skin tends to smudge over time, which can result in poor cosmetic film retention. Furthermore, the technology of Patent Document 2 forms a cosmetic film that does not feel dry after application and makes vertical wrinkles on the skin less noticeable, but can sometimes have poor dispersibility of coloring powders, making it difficult to achieve both. Furthermore, while the crosslinked organosilicon resin of Patent Document 3 is excellent in terms of finishing color unevenness and makeup retention, there has been no focus on the effect of making wrinkles and unevenness on the skin less noticeable or the maintenance of the cosmetic film by using a crosslinked organosilicon resin. It has been difficult with conventional technology to develop an oil-based cosmetic that makes wrinkles and unevenness on the skin less noticeable, has excellent dispersibility of coloring pigments, has an excellent moisturizing feel, and also has excellent cosmetic film retention.

[0005] Therefore, the oil-based cosmetic of the present invention relates to an oil-based cosmetic that has an excellent moisturizing feeling, makes wrinkles and unevenness of the skin less noticeable, and has excellent dispersibility of colored powders.The oil-based cosmetic of the present invention also relates to an oil-based cosmetic that has excellent cosmetic film retention.

[0006] In view of the above circumstances, the present inventors have conducted extensive research and have found that the problems associated with oil-based cosmetics that are excellent in cosmetic film retention, moisturizing feel, reducing the visibility of wrinkles and unevenness, and dispersibility of colored powder can be solved by combining one or more oils selected from hydrocarbon oils and ester oils, each having a melting point of 30 to 65°C, with an oil that is liquid at 25°C, an oil-based gelling agent, a colored powder, and a specific crosslinked organosilicon resin, thereby completing the present invention.

[0007] That is, the present invention includes the following: [1] An oil-based cosmetic comprising the following components (A) to (E): (A) one or more oils selected from hydrocarbon oils having a melting point of 30 to 65°C and ester oils having a melting point of 30 to 65°C, (B) an oil that is liquid at 25°C, (C) an oil-based gelling agent, (D) a colored powder, and (E) a crosslinked organosilicon resin which is an addition reaction product of the following component (X) and the following component (Y), wherein the amount of hydrogen gas generated per mass from the crosslinked organosilicon resin is 1.5 mL / g or less under standard conditions, wherein the mass ratio of component (A) to component (E), (A) / (E), is 0.02 to 50.

[0009] Preferred embodiments 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 modified within the scope of the present invention. In this specification, percentages are expressed by mass unless otherwise specified. In this specification, when a numerical range is expressed using "to", the range includes both ends of the range. In addition, the "average particle size" in this specification refers to the number average value (D50) obtained by observing the surface condition using a scanning electron microscope (JEOL, JSM-7800prime) and measuring with an image analyzer (Luzex AP, Nireco Corporation). In the case of asymmetric shapes, the median diameter D50 obtained from the distribution of the largest particle diameter is used as the average particle size in this specification.

[0010] The present invention relates to an oil-based cosmetic composition that uses a combination of components (A) to (E), in which the mass ratio of component (A) to component (E), (A) / (E), is 0.02 to 50. The oil-based cosmetic composition of the present invention provides an excellent moisturizing feel, reduces the visibility of wrinkles and unevenness on the skin, improves the dispersibility of coloring powders (good color development), and has a high cosmetic film retention effect that allows these effects to be maintained for a long period of time. In the oil-based cosmetic composition, component (B), an "oil agent that is liquid at 25°C," serves as the base of the oil-based cosmetic composition. Furthermore, in makeup cosmetics and the like, component (D), a coloring powder, is blended for the purpose of coloring. Since component (B) is generally prone to diffusion over time after application to the skin, it is difficult to maintain an oily cosmetic film on the skin for a long period of time. When the coloring powder of component (D) is dispersed in component (B), component (D) may also diffuse into the cosmetic film. As a result, the color development that should be inherently exhibited by the coloring powder of component (D) in the cosmetic film after application of the cosmetic may be reduced. Furthermore, there are techniques for obscuring wrinkles and unevenness with powder or the like, but these techniques are prone to problems such as sagging due to physical movement. Furthermore, there are techniques for forming a thick and smooth cosmetic film to obscure wrinkles and unevenness, but even when a thick film is formed by blending component (B) together with components (A) and (C), it has been extremely difficult to maintain a soft, non-sticky, thick cosmetic film that follows the movement of the skin. In the present invention, it is believed that in an oil-based cosmetic composition based on the liquid oil of component (B), the combination of component (C) and component (E) improves the dispersibility of the coloring powder (component (D)), and that the further combination with component (A) enables the formation of a thick cosmetic film. Furthermore, component (E) has a network structure, and forms a soft film on the skin while dividing and holding components (A) to (D) at regular intervals, thereby making wrinkles and unevenness less noticeable and providing an excellent moisturizing feel. Furthermore, by adopting this structure, the thickness of the cosmetic film can be maintained without change over a long period of time, and the dispersibility and color development of component (D) can also be maintained, which is thought to result in excellent cosmetic film retention.Incidentally, when a so-called paste oil having a melting point of about 30 to 65°C (component (A)) is blended into an oil-based cosmetic, the dispersibility of the colored powder (component (D)) usually decreases (see Comparative Examples 1 to 3 described below). However, in the present application, it has been surprisingly discovered that by selecting a hydrocarbon oil and / or ester oil (component (A)) as the paste oil and further combining it with components (C) and (E), the dispersibility of the colored powder is improved and maintained even in the presence of the paste oil. Furthermore, in the present application, by combining components (A) to (E), wrinkles and unevenness can be made less noticeable primarily through the oily components, without relying on powder, and therefore the moisturizing feeling is also excellent.

[0011] Component (A) used in the present invention is one or more oils selected from hydrocarbon oils and ester oils, having a melting point of 30 to 65°C. Component (A) is not particularly limited as long as it is one typically used in cosmetics, and one or more of these can be used. The melting point of component (A) is 30 to 65°C, and from the viewpoints of providing a moisturizing feeling and reducing the visibility of wrinkles and unevenness, it is preferably 35 to 60°C, and more preferably 35 to 55°C. It is preferable that component (A) does not exhibit fluidity when stored at room temperature (20°C) and deforms when stressed. The melting point of component (A) used in the present invention can be measured using Melting Point Determination Methods 2 or 3 listed in the Japanese Pharmacopoeia. Furthermore, component (A) preferably has water-holding properties or water-retentive properties. Water-holding properties refer to an oil that, despite being an oily component, retains water when mixed with water. Specifically, although not particularly limited, 50°C water is gradually added to 10 g of oil solution heated to 50°C, and the maximum mass without draining is measured. A sample that retains 10 g or more of water is preferred. Furthermore, moisture occlusion is measured by placing a piece of filter paper evenly coated with 50 mg of oil solution on the opening of a standard bottle (PS-No. 6) containing 10 g of purified water and leaving it to stand at 30°C. With the filter paper removed, the weight of the bottle is measured before and after 24 hours. As a control, a filter paper without oil solution is used for the same measurement. The transpiration inhibition rate of each test sample is calculated using the following formula to evaluate occlusion (repeated three times): Moisture occlusion (%) = (1 - [water loss with oil solution applied / water loss without oil solution applied]) x 100. A moisture occlusion rate of 85% or more is considered occlusive. Component (A) is a hydrocarbon oil and / or ester oil. Examples of hydrocarbon oils include petrolatum (melting point 38 to 60°C) and paraffin (wax) (melting point 55 to 61°C). These may be used alone or in combination. Examples of ester oils include dimer acid esters, triglycerides of fatty acids, dipentaerythrityl fatty acids, N-acylamino acid esters, hydrogenated castor oils of fatty acids, cholesterol esters of fatty acids having a fatty group with 16 to 22 carbon atoms, and phytosterol esters of fatty acids having a fatty group with 16 to 22 carbon atoms.Specific examples of component (A) include hydrocarbon oils such as petrolatum (melting point 38 to 60°C) and paraffin (wax) (melting point 55 to 61°C); dimer acid esters such as dimer dilinoleic acid (phytosteryl / isostearyl / cetyl / stearyl / behenyl (melting point 40°C); triglycerides of fatty acids such as (caprylic / capric / myristic / stearic acid) triglycerides (melting point 40°C), vegetable oils such as cacao butter, shea butter, jojoba esters, coconut oil, and mango butter; hexa(hydroxystearic acid / stearic acid / rosin acid) ) dipentaerythrityl fatty acid (melting point 37°C) and the like; N-acyl amino acid esters such as di(octyldodecyl / phytosteryl / behenyl) lauroyl glutamate, di(cholesteryl / behenyl / octyldodecyl) lauroyl glutamate, di(cholesteryl / octyldodecyl) lauroyl glutamate and the like; hydrogenated castor oil fatty acid esters such as hydrogenated castor oil stearate; cholesterol esters of fatty acids such as cholesteryl hydroxystearate; phytosteryl fatty acid esters such as macadamia nut oil fatty acid phytosteryl Among these, in terms of the effects of the present invention, it is preferable that component (A) contains at least one selected from the group consisting of hydrocarbon oils, dimer acid esters, fatty acid dipentaerythrityl, fatty acid cholesterol esters, fatty acid phytosterol esters, and N-acylamino acid esters, and in terms of dispersibility of color pigments, it is more preferable that component (A) contains at least one selected from the group consisting of dimer acid esters, fatty acid dipentaerythrityl, and N-acylamino acid esters, and in terms of moisturizing feeling, it is more preferable that component (A) contains at least one selected from the group consisting of dimer acid esters, fatty acid dipentaerythrityl, and N-acylamino acid esters. From the viewpoint of making wrinkles and unevenness less noticeable, it is more preferable that the composition contains at least one selected from the group consisting of dimer acid esters and N-acyl amino acid esters, and it is even more preferable that the composition contains an N-acyl amino acid ester, and it is particularly preferable that the composition contains at least one selected from the group consisting of di(octyldodecyl / phytosteryl / behenyl) lauroyl glutamate, di(cholesteryl / behenyl / octyldodecyl) lauroyl glutamate, and di(cholesteryl / octyldodecyl) lauroyl glutamate.In the present invention, from the viewpoint of moisturizing feeling and making wrinkles and unevenness less noticeable, it is preferable that component (A) contains one or more compounds selected from the group consisting of petrolatum as a compound with high moisture occlusion properties, and dimer acid esters, fatty acid cholesterol esters (preferably esters with fatty acids having 16 to 22 carbon atoms), fatty acid phytosterol esters (preferably esters with fatty acids having 16 to 22 carbon atoms), and N-acylamino acid esters as compounds with water-holding properties.

The upper limit is preferably 50% or less, more preferably 45% or less, even more preferably 40% or less, even more preferably 30% or less, particularly preferably 25% or less, and most preferably 20% or less. The content of component (A) is preferably in the range of 0.1 to 50%, 0.5 to 50%, 1 to 45%, 2 to 45%, 3 to 45%, 5 to 40%, 5 to 30%, 5 to 25%, 10 to 25%, or 15 to 20% relative to the oil-based cosmetic. When the content is equal to or greater than the lower limit, the moisturizing feeling and the inconspicuousness of wrinkles and unevenness are even better, and when the content is equal to or less than the upper limit, the dispersibility of colored powders is even better, so this is more preferred.

The presence or absence of a volatile oil is not particularly limited. In a preferred embodiment, component (B) contains a volatile oil. The inclusion of a volatile oil is preferred because it enhances the cosmetic film retention effect and is more effective in making wrinkles and unevenness on the skin less noticeable. However, when a volatile oil is contained in an oil-based cosmetic, a highly airtight container is also required. Therefore, from the standpoint of moldability, an optimal selection can be made depending on the formulation or container. Oils that are liquid at 25°C and are used as surface treatment agents for powders are not included in component (B).

The upper limit is preferably 90% or less, more preferably 80% or less, and even more preferably 70% or less. The range is preferably 30 to 90%, more preferably 40 to 80%, and even more preferably 50 to 70%. This range is more preferred because it provides excellent cosmetic film retention and makes wrinkles and unevenness less noticeable. Note that, when a volatile oil is contained in component (B), the content of the volatile oil is not particularly limited, but the lower limit is preferably 0.5% or more, more preferably 5% or more, and even more preferably 10% or more, and the upper limit is preferably 70% or less, more preferably 60% or less, more preferably 50% or less, and even more preferably 40% or less.

These may be used alone or in combination. The use of these oil-based gelling agents as component (C) is preferred because it provides improved usability, such as moisturizing feel, reduced visibility of wrinkles and unevenness, and non-stickiness. From the perspective of achieving the effects of the present invention, component (C) is preferably at least one selected from the group consisting of wax, dextrin fatty acid ester, fumed silicic anhydride, and organically modified clay minerals.

When the oil-based cosmetic is solid, using a wax as component (C) is preferred in terms of maintaining the cosmetic film, moisturizing feel, making wrinkles and unevenness less noticeable, and shape retention of the cosmetic, and it is more preferred if the melting point of the wax is 80°C or higher. Examples of dextrin fatty acid esters include dextrin palmitate, dextrin stearate, dextrin palmitate / stearate, dextrin myristate, dextrin laurate, dextrin (palmitate / 2-ethylhexanoate), dextrin palmitate / hexyldecanoate, dextrin behenate, and coconut oil fatty acid dextrin.

Examples of fatty acids or salts thereof include stearic acid, zinc stearate, magnesium stearate, aluminum stearate, zinc myristate, and zinc laurate. Among these, higher fatty acids having 12 or more carbon atoms or salts thereof are preferred, and metal soaps are preferred.The organically modified clay mineral is obtained, for example, by ion-exchanging a water-swelling clay mineral with a cationic surfactant such as an alkyl quaternary ammonium salt, and in the present invention, those exchanged with benzyldimethylstearylammonium ions or dimethyldistearylammonium ions are particularly preferred. The water-swelling clay mineral is a type of colloidal hydrated aluminum silicate having a three-layer structure, and is generally represented by the following general formula (1) (X, Y): ２３ (Si, Al) ４ O １０ (OH) ２ Z.nH ２ O... (1) where X = Al, Fe, Mn, Cr, Y = Mg, Fe, Ni, Zn, Li, and Z = K, Na, Ca. Specific examples include natural or synthetic montmorillonites such as montmorillonite, laponite, and hectorite (wherein (OH) in the above general formula is replaced with fluorine), as well as synthetic micas known as sodium silicic mica and sodium or lithium taeniolite. Montmorillonite and hectorite are particularly preferred as water-swellable clay minerals. Commercially available organically modified clay minerals include Benton 27V and Benton 38V BC (manufactured by ELEMENTIS). Examples of oil-soluble polyurethanes include OILKEMIA 5S CC POLYMER (manufactured by Lubrizol Corporation, oil-soluble polyurethane polymer solids content 30%, tri(caprylic / capric acid)glyceryl mixture), (hydrogenated polybutadiene / glycol / HDI) copolymer (solids content 20%, cetyl ethylhexanoate mixture), etc. Component (C) can be used alone or in combination of two or more of the above.

[0016] The content of component (C) used in the present invention is not particularly limited, and the lower limit in the oil-based cosmetic is preferably 0.5% or more, more preferably 2% or more, even more preferably 5% or more, and even more preferably 7% or more. The upper limit is preferably 25%, more preferably 20% or less, and even more preferably 15% or less. The range is preferably 0.5 to 25%, more preferably 2 to 20%, even more preferably 5 to 15%, and even more preferably 7 to 15%. This range is more preferable because it provides better cosmetic film retention, moisturizing feel, and less noticeable wrinkles and unevenness.

[0017] The colored powder of component (D) used in the present invention is blended for the purpose of controlling the color tone and finished color tone of oil-based cosmetics. There are no particular limitations on the colored powder as long as it is generally suitable for use in cosmetics, and any particle shape, particle diameter, particle surface condition, etc. can be used. There are no particular limitations on the shape (plate-like, spindle-like, needle-like, etc.), particle diameter (aerosol-like, fine particles, pigment-grade, etc.), particle structure (porous, non-porous, etc.), etc., and examples thereof include inorganic powders, glitter powders, organic powders, composite powders, etc. Examples of the colored powder of component (D) include inorganic powders such as inorganic pigments such as titanium oxide, red iron oxide, yellow iron oxide, black iron oxide, ultramarine, Prussian blue titanium oxide, black titanium oxide, ferric iron oxide, ultramarine, chromium oxide, titanium-titanium oxide sintered product, zinc oxide, aluminum oxide, cerium oxide, zirconium oxide, carbon black, and chromium hydroxide; organic pigment powders such as Red No. 201, Red No. 202, Red No. 205, Red No. 226, Red No. 228, Orange No. 203, Orange No. 204, Blue No. 404, and Yellow No. 401; and organic powders such as organic pigments such as zirconium, barium, or aluminum lake, such as Red No. 3, Red No. 104, Red No. 106, Orange No. 205, Yellow No. 4, Yellow No. 5, Green No. 3, and Blue No. 1. In addition, powders obtained by combining these coloring powders may also be used, and examples thereof include luster powders such as titanium mica, iron oxide-treated mica (titanium oxide-coated mica), iron oxide-treated titanium mica, organic pigment-treated mica, titanium oxide-treated glass powder, and iron oxide titanium oxide-treated glass powder; pigment powders such as organic dye lake pigments; and composite powders such as fine particle titanium oxide-coated mica titanium, fine particle zinc oxide-coated mica titanium, barium sulfate-coated mica titanium, titanium oxide-containing silicon dioxide, and zinc oxide-containing silicon dioxide. One or more of these powders may be used. Furthermore, one or more of these powders may be combined. Component (D) may be surface-treated with one or more of a fluorine compound, a silicone compound, a fatty acid or a salt thereof, an acylated amino acid or a salt thereof, lecithin, hydrogenated lecithin, collagen, a hydrocarbon, a higher alcohol, an ester, a wax, a surfactant, and the like.From the viewpoint of forming a uniform cosmetic film with components (A) and (E) and improving the retention of the cosmetic film, the moisturizing feeling, and the dispersibility of the colored powder, it is more preferable to use a colored powder that has been surface-treated with one or more of a fatty acid or its salt, an acylated amino acid or its salt. Even more preferable is the use of a colored powder that has been surface-treated with an acylated amino acid or its salt (a colored powder that has been surface-treated with a surface treatment agent containing an acylated amino acid or its salt). One or more of the fatty acids or their salts, and the acylated amino acids or their salts may be used in combination.

[0018] Specifically, the term "acylated amino acid or its salt" refers to a compound in which an acyl group, preferably a saturated fatty acid having 12 to 20 carbon atoms, is condensed with the amino group of an amino acid, or a salt thereof. Examples of the "acyl group" include a stearoyl group, a lauroyl group, a palmitoyl group, and a cocoyl group. The "salt" can be selected from alkali metal salts such as sodium and potassium, and alkaline earth metal salts. Specific examples of acylamino acid salts include, but are not limited to, N-lauroyl lysine, sodium N-stearoyl glutamate, disodium N-stearoyl glutamate, sodium N-lauroyl glutamate, sodium N-lauroylaspartate, sodium palmitoyl sarcosine, magnesium palmitoyl glutamate, and sodium dilauramidoglutamide lysine.

[0019] Commercially available surface treatment agents containing "acylamino acid or a salt thereof" include, for example, LL treatment and LL-VSTAL treatment (manufactured by Daito Chemical Industry Co., Ltd.) as surface treatment agents containing N-lauroyl lysine, ASL treatment (manufactured by Daito Chemical Industry Co., Ltd.) as surface treatment agents containing dilauramidoglutamide lysine sodium, NAI treatment (manufactured by Daito Chemical Industry Co., Ltd.) as surface treatment agents containing N-stearoyl glutamic acid disodium, and ASI treatment (manufactured by Daito Chemical Industry Co., Ltd.) as surface treatment agents containing N-lauroyl aspartic acid sodium. In the present invention, it is particularly preferable to select a colored powder that has been surface-treated with a surface treatment agent containing dilauramidoglutamide lysine sodium, as this improves cosmetic film retention, moisturizing feeling, and dispersibility of the colored powder.

[0020] The average particle size of component (D) is, for example, 0.001 to 1 μm, and may be 0.01 to 0.8 μm. Unless otherwise specified, the average particle size is the number-based value (D50) determined by observing the surface condition using a scanning electron microscope and measuring 1,000 particles using an image analyzer. The content of component (D) used in the present invention is not particularly limited, and is preferably 0.1% or more, more preferably 0.5% or more, even more preferably 1% or more, and even more preferably 2% or more in the oil-based cosmetic. It is also preferably 40% or less, more preferably 30% or less, and even more preferably 20% or less. The range is preferably 0.1 to 40%, more preferably 0.5 to 40%, even more preferably 1 to 30%, and even more preferably 2 to 20%. This range is more preferred because it provides better cosmetic film retention, moisturizing feel, and colored powder dispersibility. In addition, the content of component (D) here refers to the total amount of the surface-treated colored powder, including the surface treatment agent, when component (D) is a surface-treated colored powder. Furthermore, from the viewpoint of the above-mentioned effects, the content of the colored powder that has been subjected to one or more surface treatments consisting of a fatty acid or a salt thereof, an acylated amino acid or a salt thereof, in the oil-based cosmetic is preferably 0.1 to 40%, more preferably 0.5 to 30%, or even 1 to 20%, or may be 1 to 10%.

[0021] Component (E) used in the present invention is described in detail below. Component (E) is a crosslinked organosilicon resin that is the addition reaction product of components (X) and (Y) below, and generates hydrogen gas in an amount per mass of 1.5 mL / g or less under standard conditions.

[0022] [Component (X)] Component (X) is an alkenyl group-containing organosilicon resin represented by the following average composition formula (1) and containing one or more alkenyl groups per molecule. As component (X), the alkenyl group-containing organosilicon resin represented by average composition formula (1) can be used alone or in combination of two or more. [In the formula, R １ are each independently an alkenyl group having 2 to 8 carbon atoms, and R ２are each independently a group selected from an alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, and an aralkyl group having 7 to 30 carbon atoms. ３ are each independently an organopolysiloxane-containing group, and the R ２ and each R ３ ３ SiO １／２ R in units ３ At least one of the groups is an organopolysiloxane-containing group. a1, a2, a3, b, c, and d are numbers that satisfy 0<a1≦5, 0<a2≦400, 0≦a3≦400, 0≦b≦320, 0≦c≦320, and 0<d≦1,000, and 0.5≦(a1+a2+a3) / d≦1.5.

[0023] [Component (Y)] Component (Y) is an organohydrogenpolysiloxane represented by the following average compositional formula (2) and containing two or more hydrosilyl groups (groups having a hydrogen atom directly bonded to a silicon atom) per molecule. As component (Y), the alkenyl group-containing organosilicon resin represented by average compositional formula (2) can be used alone or in combination of two or more. The addition reaction amount is an amount that results in 0.5 to 1.2 moles of hydrosilyl groups per mole of alkenyl groups in component (X), preferably 0.5 to 1.2 moles, more preferably 0.8 to 1.2 moles, and even more preferably 0.9 to 1.1 moles. [In the formula, R ２ is the same as above, and R ４ are each independently a hydrogen atom or the above R ２ and all R ４ Two or more of them are hydrogen atoms, and e, f, g, and h are 0 or positive numbers, provided that 2≦e+f+g+h<32 is satisfied.

[0024] In the above formula, R １ are each independently an alkenyl group having 2 to 8 carbon atoms. More specific examples include a vinyl group, an allyl group, an isopropenyl group, a butenyl group, a pentenyl group, a hexenyl group, a cyclohexenyl group, and an octenyl group. In particular, a vinyl group and an allyl group are preferred, and a vinyl group is more preferred.

[0025] In the above formula, R ２are each independently a group selected from an alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, or an aralkyl group having 7 to 30 carbon atoms. Among these, an alkyl group, an aryl group, an aralkyl group, or a fluorine-substituted alkyl group having 1 to 10 carbon atoms is preferred. More specifically, examples thereof include a methyl group, an ethyl group, a propyl group, a butyl group, a pentyl group, a cyclopentyl group, a cyclohexyl group, a phenyl group, a tolyl group, a trifluoropropyl group, etc. In particular, R ２ is preferably an alkyl group having 1 to 5 carbon atoms (preferably an alkyl group having 1 to 3 carbon atoms), a phenyl group, or a trifluoropropyl group, and more preferably an alkyl group having 1 to 5 carbon atoms (preferably an alkyl group having 1 to 3 carbon atoms). ２ A part of the group may contain one or more groups selected from a hydroxyl group or an alkoxy group having 1 to 8 carbon atoms.

[0026] In the alkenyl group-containing organosilicon resin represented by the above formula (1), a1 is 0<a1≦5, preferably 0<a1≦4.5, more preferably 1≦a1≦4, and even more preferably 1≦a1≦3. If a1 is greater than 5, the possibility of gelation increases and film-forming properties are poor. Furthermore, having a value below the lower limit is preferable because it improves cosmetic film retention. a2 is 0≦a2≦400, preferably 0≦a2≦100, and more preferably 0≦a2≦50. a3 is 0≦a3≦400, preferably 0≦a3≦100, and more preferably 0≦a3≦50. a3 may be 0. If a3 is greater than 400, the melting point of the resin will be low, resulting in poor film-forming properties. b and c are 0≦b≦320 and 0≦c≦320, with b=0 and c=0 being preferred. d is a number satisfying 0<d≦1,000 and 0.5≦(a1+a2+a3) / d≦1.5. If the value of (a1+a2+a3) / d is less than the lower limit, the degree of crosslinking increases and the molecular weight increases, resulting in a gel-like state. If it exceeds the upper limit, the molecular weight decreases and film-forming properties are poor. Preferably, d is a number satisfying 0.7≦(a1+a2+a3) / d≦1.2, more preferably 0.7≦(a1+a2+a3) / d≦1.0. Furthermore, d is 0<d≦1,000, preferably 0<d≦500, more preferably 1≦d≦200, and even more preferably 1≦d≦100. Being within the above range is preferable because it provides a more excellent moisturizing feel.

[0027] The alkenyl group-containing organosilicon resin represented by the above formula (1) is a Q unit (SiO ４／２ ), M units (R ２ ３ SiO １／２ and R １ R ２ ２ SiO １／２ ) is an essential structure, and D unit (R ２ ２ SiO ２／２ ), T unit (R ２ SiO ３／２) in any structure. It may be solid or liquid at 25°C, but solid is preferred from the viewpoint of film-forming properties. Examples include MQ resin, MTQ resin, MDQ resin, and MDTQ resin. The weight-average molecular weight of the alkenyl group-containing organosilicon resin represented by formula (1) is preferably in the range of 1,000 to 30,000, and more preferably in the range of 3,000 to 15,000 from the viewpoint of performance and workability such as filtration. The weight-average molecular weight can be determined as the weight-average molecular weight converted into polystyrene by gel permeation chromatography (GPC) analysis.

[0028] The organohydrogenpolysiloxane represented by the above formula (2) has two or more hydrosilyl groups in one molecule. ４ are preferably each independently a hydrogen atom or a monovalent hydrocarbon group having 1 to 30 carbon atoms and no aliphatic unsaturated bond, and all R ４ At least two of them are hydrogen atoms.

[0029] In the above formula (2), e, f, g, and h are 0 or positive numbers and may be selected to satisfy the relationship 2≦e+f+g+h<32. Preferably, g=0 and h=0 (i.e., 2≦e+f<32), more preferably, e=2, 0≦f<30, g=0, and h=0, and even more preferably, e=2, 10≦f≦30, g=0, and h=0. This range is preferred because it provides better dispersibility of the coloring powder. If the number of silicon atoms contained in the component is 32 or more, the crosslinked organosilicon resin tends to embrace the solvent, resulting in a gel. As a result, a sticky film tends to form after the solvent evaporates. If the number of silicon atoms contained in component (Y) is less than 32, the crosslinked organosilicon resin tends to dissolve in the solvent and become a liquid. As a result, a non-sticky film tends to form after the solvent evaporates.

[0030] The above R ３ are each independently an organopolysiloxane-containing group, or ２ Examples of the organopolysiloxane-containing group include groups represented by the following general formulas (3) to (6): ３ ３SiO １／２ In each of the units, one or more R ３ is an organopolysiloxane-containing group. ３ A part of may be a hydroxyl group. (In the formula, R ２ are the same as above, m and i are integers that satisfy 0≦m≦5 and 0≦i≦500, and j1 to j3 are each an integer of 0 or more and 2 or less.

[0031] m is an integer satisfying 0≦m≦5, preferably 0≦m≦2, and i is an integer satisfying 0≦i≦500, preferably 1≦i≦100, more preferably 1≦i≦50. If i is greater than 500, the melting point of the resin will be low, resulting in poor film-forming properties. j1 to j3 are each integers of 0 or more and 2 or less.

[0032] In the above formula (1), it is preferable that b = 0 and c = 0. When b and c are 0, the alkenyl group-containing organosilicon resin does not contain a flexible skeleton such as D units or T units, and is composed only of M units and Q units. By using an alkenyl group-containing organosilicon resin that does not contain D units or T units as a raw material, the crosslinked organosilicon resin, which is the addition reaction product, can form a strong coating.

[0033] In the above formula (2), it is preferable that g = 0 and h = 0. When g and h are 0, the organohydrogenpolysiloxane does not contain branched components such as T units and Q units, and is a linear molecule composed only of M units and D units. By using a linear organohydrogenpolysiloxane as a raw material, the crosslinked organosilicon resin, which is the addition reaction product, can form a flexible coating.

[0034] Furthermore, the Y component may contain two or more organohydrogenpolysiloxanes represented by formula (2). As the chain length of the organohydrogenpolysiloxane represented by formula (2) increases, it has the effect of imparting flexibility to the organosilicon resin. Therefore, for example, by using two types of organohydrogenpolysiloxanes represented by formula (2) with different chain lengths, the physical properties of the coating can be controlled.

[0035] [Physical Properties of the Crosslinked Organosilicon Resin of Component (E)] The weight-average molecular weight of the crosslinked organosilicon resin of component (E) used in the present invention is preferably 5,000 to 1,000,000, more preferably 8,000 to 500,000, and even more preferably 10,000 to 500,000. Having a molecular weight within this range is more preferable in terms of performance and ease of filtration and other operations. The weight-average molecular weight can be determined as a polystyrene-equivalent weight-average molecular weight by gel permeation chromatography (GPC) analysis (the same applies hereinafter).

[0036] The crosslinked organosilicon resin of component (E) used in the present invention may be solid, gel, or liquid at 25°C. For example, by dissolving it in a liquid oil and volatilizing it, a film can be easily formed. This film is a brittle and strong film before crosslinking, but after crosslinking, its brittleness improves and a soft, non-sticky film is obtained. From the viewpoint of film-forming ability, a solid or gel state is preferred, and a solid state is more preferred. Film-forming ability can be determined by dropping 1.5 g of a solution diluted to 30% by mass with isododecane or decamethylcyclopentasiloxane onto PTFE (fluororesin), drying at 105°C for 3 hours, and determining whether a free-standing film is formed. If a film is not formed, oil will seep out from cracks in the film, significantly reducing oil resistance and resulting in poor skin conformability, resulting in an unnatural finish.

[0037] The crosslinked organosilicon resin of component (E) used in the present invention can be more suitably used as a film-forming agent. While organosilicon resins before crosslinking form brittle, strong films, crosslinked organosilicon resins after crosslinking have improved brittleness and form flexible films without stickiness. This is because organosilicon resins before crosslinking form strong films, but crosslinking with flexible chains imparts flexibility to the film. Generally, hard films tend to have low flexibility, while highly flexible films tend to be soft, so film strength and flexibility have been considered to be in a trade-off relationship. However, despite forming a strong film, this crosslinked organosilicon resin has the characteristic of having excellent followability due to its high flexibility.

[0038] In addition, the coating formed by the crosslinked organosilicon resin of component (E) used in the present invention has significantly improved oil resistance to oil agents such as sebum, compared to the coating formed by the organosilicon resin before crosslinking.Organosilicon resins tend to have improved oil resistance as their molecular weight increases, but since there is a limit to how much the molecular weight of organosilicon resin can be increased, there is also a limit to the oil resistance.Crosslinking of organosilicon resins with crosslinking agents leads to a pseudo-increase in the molecular weight of the organosilicon resin, which has the effect of raising this limit.Therefore, crosslinked organosilicon resins have oil resistance that cannot be achieved by conventional organosilicon resins.

[0039] A crosslinked organosilicon resin in which f in the above formula (2) is an integer that satisfies the condition 0<f<30 is solid at 25°C and has particularly excellent film-forming properties.

[0040] In addition, f in the above formula (2) satisfies 0≦f<30, and R ４ A crosslinked organosilicon resin in which two of the groups are hydrogen atoms is solid at 25°C and has particularly excellent film-forming properties. ４ If three or more of these are hydrogen atoms, there is a high possibility that the composition will become gel-like when the diluting solvent is removed. In this case, the composition will have film-forming properties, but will have a gel-like feel.

[0041] In the above formula (1), a1 satisfies 0<a1≦3, and f in the above formula (2) satisfies 0≦f<30, and R ４ Crosslinked organosilicon resins in which two of the radicals are hydrogen atoms are solid at 25°C and can be obtained as crosslinked organosilicon resins with particularly excellent film-forming properties. The resulting films exhibit particularly excellent flex resistance and oil resistance.

[0042] The amount of hydrogen gas generated per mass from the crosslinked organosilicon resin is 1.5 mL / g or less under standard conditions. If the amount exceeds 1.5 mL / g, the resin may generate hydrogen gas over time or react with the remaining hydroxyl or alkoxy groups and hydrosilyl groups, increasing the likelihood of viscosity increase over time and reducing stability over time. The amount of hydrogen gas generated is preferably 0.01 to 1.5 mL / g, more preferably 0.01 to 1.2 mL / g, and even more preferably 0.02 to 1.0 mL / g.

[0043] The amount of hydrogen gas per mass can be calculated from the volume of hydrogen gas generated by the reaction of hydrosilyl groups with a base. Examples of methods include, but are not limited to, the following: <Method for measuring the amount of hydrogen gas> 10 g of a 20% by mass aqueous solution of sodium hydroxide is added dropwise to a mixed solution of 50 g of a crosslinked organosilicon resin diluted to 50% by mass with decamethylcyclopentasiloxane and 10 g of 1-butanol. The amount of hydrogen gas per mass is determined by dividing the volume of the generated hydrogen gas by the pure content of the crosslinked organosilicon resin.

[0044] [Production Method] The crosslinked organosilicon resin of component (E) used in the present invention can be synthesized by various methods known in the art. For example, crosslinking can be achieved by reacting the surface silanol groups of an organosilicon resin with an organopolysiloxane having hydroxyl groups at both ends. However, since it is difficult to completely control the amount of silanol groups on the organosilicon resin surface, it is difficult to accurately control the amount of organopolysiloxane to be crosslinked. Alternatively, it can be synthesized by the addition reaction of an organosilicon resin having hydrosilyl groups with an organopolysiloxane having alkenyl groups at both ends. However, the hydrosilyl groups in the organosilicon resin have low reactivity, and the remaining hydrosilyl groups react over time, resulting in increased viscosity and the generation of hydrogen gas. Therefore, a preferred method for producing a silicone-crosslinked crosslinked organosilicon resin is the addition reaction of an organosilicon resin having alkenyl groups with an organopolysiloxane having hydrosilyl groups at both ends.

[0045] The method for producing a crosslinked organosilicon resin by the hydrosilylation reaction is described in more detail below. In the hydrosilylation reaction step between the alkenyl group-containing organosilicon resin represented by the average composition formula (1) and the organohydrogenpolysiloxane represented by the formula (2), the molar ratio of terminal hydrosilyl groups to unsaturated groups can be selected from the range of 0.5 to 2.0, preferably 0.5 to 1.2, more preferably 0.8 to 1.2, and even more preferably 0.9 to 1.1. If this ratio is too high, the amount of residual hydrosilyl groups will increase, which may result in poor stability over time.

[0046] This hydrosilylation reaction is preferably carried out in the presence of a platinum or rhodium catalyst. Examples of suitable catalysts include chloroplatinic acid, alcohol-modified chloroplatinic acid, and chloroplatinic acid-vinylsiloxane complexes. Furthermore, since an excessive amount of catalyst will cause coloration of the sample, the amount of platinum or rhodium used is preferably 50 ppm or less, and more preferably 20 ppm or less.

[0047] Furthermore, the above addition reaction may be carried out in the presence of an organic solvent, if necessary. Examples of the organic solvent include cyclic organopolysiloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane; short-chain silicone oils such as methyl trimethicone and short-chain dimethicone; aromatic hydrocarbons such as toluene and xylene; ketone-based organic solvents such as acetone, methyl ethyl ketone, diethyl ketone, and methyl isobutyl ketone; aliphatic hydrocarbons such as hexane, heptane, octane, decane, isododecane, and cyclohexane; and aliphatic alcohols such as methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-methyl-1-propanol, 2-butanol, 2-methyl-2-propanol, 1-pentanol, 2-methylbutanol, 2-pentanol, 1-hexanol, 2-methylpentanol, 1-heptanol, 1-octanol, 1-nonanol, 1-decanol, phenol, benzyl alcohol, ethylene glycol, and 1,2-propylene glycol. In particular, ethanol, 1-propanol, and 2-propanol are preferred from the viewpoint of reactivity.

[0048] The amount of the solvent used is preferably 1 to 80% by mass, more preferably 5 to 50% by mass, of the entire reaction solution (system). Within this range, the reaction system is maintained uniformly, and the reaction proceeds efficiently.

[0049] The crosslinked organosilicon resin of component (E) used in the present invention can be dissolved in an organic solvent and used as a pre-dissolved product. The organic solvent used during the addition reaction may be used as is, or may be replaced after the addition reaction. The replacing organic solvent can be selected depending on the intended use. The replacing solvent is not particularly limited and can be selected from the organic solvents described above. When the dissolving solvent is a volatile oil, it is preferable that a film is formed and its effects are exerted soon after application of the cosmetic. From this perspective, it is preferable to incorporate a volatile oil having a boiling point of 240°C or less. Among these, silicone oils such as decamethylpentasiloxane, methyltrimethicone, and dimethicone, volatile hydrocarbon oils such as isododecane, and lower alcohols such as ethanol and isopropanol are particularly preferred, and can be selected and combined appropriately depending on the type of base material used in the cosmetic. One or more types can be used in combination as needed. Non-volatile oils may also be used; there are no limitations.

[0050] The addition reaction conditions are not particularly limited, but it is preferable to heat under reflux at a temperature of 50 to 150°C, more preferably 80 to 120°C, for about 1 to 10 hours.

[0051] It is also possible to include a step of removing the rhodium catalyst or platinum catalyst used with activated carbon after the addition reaction. The amount of activated carbon used is preferably 0.001 to 5.0 mass % of the entire system, and more preferably 0.01 to 1.0 mass %. If the amount is within this range, coloration of the sample can be further suppressed.

[0052] After the addition reaction, a step of removing the remaining hydrosilyl groups can be included as needed. In particular, when used in applications such as cosmetics, the hydrosilyl groups may be deactivated over time by dehydrogenation. Since hydrogen gas is generated, which is a safety issue, it is preferable to include a step of removing the hydrosilyl groups.

[0053] The hydrosilyl group removal process involves adding a basic catalyst to hydrolyze unreacted hydrosilyl groups, followed by neutralization by adding an acidic catalyst in an amount equal to the molar equivalent of the basic catalyst. Examples of basic catalysts include strongly basic catalysts and weakly basic catalysts. Examples of strongly basic catalysts include alkali metal hydroxides such as lithium hydroxide, sodium hydroxide, potassium hydroxide, calcium hydroxide, and barium hydroxide. Examples of weakly basic catalysts include alkali metal carbonates such as sodium carbonate and calcium carbonate, and alkali metal bicarbonates such as sodium bicarbonate and potassium bicarbonate. In terms of promoting the dehydrogenation reaction, it is particularly preferable to use a strongly basic catalyst, and specifically, sodium hydroxide is preferred. Examples of acidic catalysts include inorganic acids such as hydrochloric acid, sulfuric acid, sulfurous acid, oleum, and phosphoric acid; sulfonic acid oxalic acid such as p-toluenesulfonic acid, methanesulfonic acid, and trifluoromethanesulfonic acid; and carboxylic acids such as formic acid, acetic acid, propionic acid, benzoic acid, citric acid, and trifluoroacetic acid.

[0054] In general, rather than using an acid or base alone, it is preferable to use them in combination with water and heat them at a temperature below the boiling point of water. This process converts hydrosilyl groups (SiH groups) into hydroxysilyl groups (SiOH groups). However, when a crosslinked organosilicon resin is treated with a base catalyst, the silanol groups and alkoxy groups in the organosilicon resin react, causing changes in physical properties, so it is not preferable to remove hydrosilyl groups using this method.

[0055] The content of component (E) used in the present invention is not particularly limited, and is preferably 0.3% or more, more preferably 1.5% or more, and even more preferably 3% or more, in terms of solids, relative to the total amount of the oil-based cosmetic. It is also preferably 20% or less, more preferably 15% or less, and even more preferably 10% or less. It is also preferably 0.3 to 20%, more preferably 1.5 to 15%, even more preferably 3 to 15%, and particularly preferably 3 to 10%. This range is more preferable because it provides superior cosmetic film retention, less noticeable wrinkles and irregularities, and better dispersibility of colored powders.

[0056] In the present invention, the composition is obtained by appropriately incorporating the above-described components (A) and (E), but the mass ratio (A) / (E) of component (A) to component (E) has a lower limit of 0.02 or more, preferably 0.05 or more, more preferably 0.10 or more, even more preferably 0.40 or more, even more preferably 1.00 or more, and particularly preferably 1.50 or more. The upper limit is 50 or less, preferably 40 or less, more preferably 30 or less, even more preferably 10 or less, and even more preferably 5 or less. The range may be 0.02 to 50, 0.05 to 40, 0.10 to 40, 0.40 to 30, 0.50 to 10, 1.00 to 10, or 1.50 to 5. If the content is equal to or greater than the lower limit, the moisturizing feeling, the inconspicuousness of wrinkles and unevenness, etc. are better, and if the content is equal to or less than the upper limit, the durability of the cosmetic film, the inconspicuousness of wrinkles and unevenness, the dispersibility of colored powder, etc. are better, which is more preferable.

[0057] In the present invention, component (F) may contain a polyhydric alcohol. There are no particular limitations on the polyhydric alcohol, so long as it is one that is commonly used in cosmetics. The inclusion of component (F) further improves the inconspicuousness of wrinkles and unevenness. Specifically, it is preferable to include polyhydric alcohols such as propylene glycol, 1,3-butylene glycol, 1,2-pentanediol, dipropylene glycol, tripropylene glycol, glycerin, diglycerin, polyethylene glycol, sorbitol, maltitol, and ethylhexylglycerin. These polyhydric alcohols can be used alone or in combination with one or more other types. It is particularly preferable for component (F) to contain a glycol ether such as dipropylene glycol, tripropylene glycol, 1,3-butylene glycol, or ethylhexylglycerin. The inclusion of such glycol ethers in oil-based cosmetics is preferable because they do not inhibit the film-forming properties of component (E), improve preservative properties, and provide excellent inconspicuousness of wrinkles and unevenness. The content of component (F) in the present invention is not particularly limited, but the lower limit is preferably 0.05% or more, more preferably 0.1% or more, and even more preferably 0.2% or more, and the upper limit is preferably 2% or less, more preferably 1.5% or less, even more preferably 1% or less, and even more preferably 0.5% or less. This range is preferred because the effects of the polyhydric alcohol are easily exhibited. The range may be 0.05 to 2%, 0.1 to 1.5%, 0.2 to 1%, or 0.2 to 0.5%.

[0058] The oil-based cosmetic of the present invention may further contain a silicone surfactant as component (G) to reduce the visibility of wrinkles and unevenness and to improve the dispersibility of colored powders. Component (G) silicone surfactant is a copolymer having at least an organopolysiloxane group and a hydrophilic group. Examples include, but are not limited to, polyether-modified silicones having polyether chains as hydrophilic groups, and polyglycerin-modified silicones having polyglycerin chains as hydrophilic groups. The silicone surfactant may be a graft copolymer having an organopolysiloxane group as the main chain and hydrophilic groups in the side chains, or a linear block copolymer or crosslinked polymer in which organopolysiloxane groups and hydrophilic groups are alternately bonded. The organopolysiloxane group may be linear or branched, or may be co-modified with an organic group such as an alkyl group or a fluorine-substituted alkyl group.

[0059] Component (G) is not particularly limited, but examples of components having a linear organopolysiloxane group as the main chain and polyoxyalkylene groups in the side chains include polyoxyalkylene-modified organopolysiloxanes and polyoxyalkylene / alkyl-co-modified organopolysiloxanes, and examples of commercially available products include KF-6017 (manufactured by Shin-Etsu Chemical Co., Ltd.), 5200 Formulation Aid (manufactured by Dow Corning Toray Co., Ltd.), and ABILEM97S (manufactured by EVONIC GOLD SCHMIDT). Furthermore, examples of compounds having a branched organopolysiloxane group as the main chain and grafted with polyoxyalkylene groups (silicone branched polyether-modified silicones) include PEG-9 polydimethylsiloxyethyl dimethicone, lauryl PEG-9 polydimethylsiloxyethyl dimethicone, cetyl PEG-9 polydimethylsiloxyethyl dimethicone, cetyl PEG / PPG-10 / 1 dimethicone, and commercially available products thereof include KF-6028 (HLB 4), KF-6038 (HLB 3) (both manufactured by Shin-Etsu Chemical Co., Ltd.), and ABILEM 90 (manufactured by EVONIC GOLD SCHMIDT). Furthermore, examples of compounds in which polyglycerin groups are grafted onto a main chain of an organopolysiloxane group having a branched structure (silicone branched polyglycerin-modified silicone) include lauryl polyglyceryl 3-polydimethylsiloxyethyl dimethicone, and a commercially available product thereof is KF-6105 (manufactured by Shin-Etsu Chemical Co., Ltd.). Specific examples of the block copolymer type include polyoxyethylene-butylene-dimethylpolysiloxane copolymer and polyoxyethylene-polyoxypropylene-butylene-dimethylpolysiloxane copolymer, and commercially available products thereof are FZ-2250 and FZ-2233 (both manufactured by Dow Corning Toray Co., Ltd.) and SILWET 236-L (manufactured by Nippon Unicar Co., Ltd.).

[0060] The HLB of component (G) is preferably 2 to 7, and particularly preferably 3 to 5. Within this range, the cosmetic film formed by components (A) and (E) is excellent in terms of preventing the visibility of wrinkles and unevenness, and the dispersibility of the colored powder of component (D) is excellent, which is preferable. The HLB (hydrophile-lipophile balance) value used in the present invention is a value obtained by the Griffin method. The weight-average molecular weight of component (G) is not particularly limited, but is preferably 500 to 200,000, and more preferably 1,000 to 10,000.

[0061] Component (G) can be used alone or in combination with two or more of the above-mentioned examples. From the viewpoint of reducing the visibility of wrinkles and unevenness and improving the dispersibility of colored powders, in order to maintain the cosmetic film of components (A) and (E), and component (D), even when the ambient environment changes in the oil-based cosmetic composition, on the lips immediately after application, and over time when affected by sweat, water, and sebum, it is more preferable to use an organopolysiloxane having a linear or branched structure as the main chain and polyoxyalkylene groups in the side chain, specifically a polyoxyalkylene-modified organopolysiloxane or a polyoxyalkylene / alkyl-co-modified organopolysiloxane. Among these, component (G) is preferably at least one selected from the group consisting of PEG-9 polydimethylsiloxyethyl dimethicone, lauryl PEG-9 polydimethylsiloxyethyl dimethicone, and lauryl polyglyceryl 3-polydimethylsiloxyethyl dimethicone.

[0062] The content of component (G) in the present invention is not particularly limited, but the lower limit is preferably 0.1% or more, more preferably 0.3% or more, and even more preferably 0.5% or more, and the upper limit is preferably 3% or less, more preferably 2% or less, and even more preferably 1% or less. This range is more preferable because it provides better dispersibility of the coloring powder.

[0063] In addition to the above components (A) to (F) and component (G), the oil-based cosmetic of the present invention can contain appropriate ingredients commonly used in cosmetics, provided that the ingredients do not impair the effects of the present invention. Examples of such ingredients include oils other than components (A), (B), and (C), powders other than component (D), film-forming agents other than component (E), preservatives, antioxidants, medicinal ingredients, UV absorbers, fragrances, aqueous ingredients other than component (F), moisturizers, surfactants other than component (G), etc.

These may be surface-treated with a fluorine compound, silicone oil, powder, oil, gelling agent, emulsion polymer, surfactant, etc. These powders may be used alone or in combination, and may also be used in combination. The total amount of the plate-like powder and spherical powder, excluding the pearlescent agent and colored powder, may be less than 10% by mass of the oil-based cosmetic.Examples of ultraviolet absorbers include anthranil-based ones, dibenzoylmethane-based ones such as butyl methoxydibenzoylmethane and isopropyl dibenzoylmethane, cinnamic acid-based ones such as ethylhexyl methoxycinnamate, isopropyl methoxycinnamate and 2-ethoxyethyl 4-methoxycinnamate, salicylic acid-based ones such as ethylhexyl salicylate, camphor-based ones, benzophenone-based ones such as benzophenone-3, triazine-based ones such as bis-ethylhexyloxyphenol methoxyphenyl triazine and ethylhexyl triazone, benzotriazole, benzalmalonate-based ones, benzimidazole-based ones, bis-benzoazolyl-based ones, p-aminobenzoic acid-based ones, diphenyl acrylate-based ones such as octocrellin, and urocanic acid-based ones.

[0065] The oil-based cosmetic of the present invention has oil as a continuous phase and is substantially free of water. In the present invention, "substantially free of water" means that the cosmetic does not contain any water at all, or that even if it does contain water, it does not affect the present invention, and the content is preferably 5% or less, more preferably 1% or less.

[0066] The oily cosmetic of the present invention can be produced using a conventional method, although it is not particularly limited thereto. For example, it can be obtained by dissolving and mixing components (A) to (C) at 70 to 110°C, and then adding components (D) and (E) to the mixture, mixing, and dispersing. Alternatively, components (D) and (E) may be mixed in advance and then added, or component (D) and any of components (A) to (C) may be dispersed in advance.

[0067] The oil-based cosmetic of the present invention is not particularly limited in its form, and may be in any of liquid, semi-solid, gel, cream, and solid forms. Among these, semi-solid and solid forms are preferred from the viewpoint of providing an excellent moisturizing feeling and making wrinkles and unevenness on the skin less noticeable. Note that the semi-solid and solid forms referred to here refer to those that do not have fluidity at 25°C, and more specifically, those that can maintain their shape for 10 minutes or more when tilted at 45°.

[0090] (Evaluation Method 1) A panel of 20 cosmetic evaluation experts used the lipsticks of the Examples and Comparative Examples and conducted a sensory evaluation. Regarding "moisturizing feeling," whether or not the cosmetic film felt moisturizing or dry when the cosmetic was used, regarding "invisibility of wrinkles and unevenness," whether or not the finished film was smooth and wrinkles and unevenness were inconspicuous immediately after application, regarding "dispersibility of color pigment (color powder)," a visual evaluation was conducted regarding the color development on the skin upon application, and regarding "retention of cosmetic film," whether or not a cosmetic film remained on the lips when wiped off with a tissue 3 hours after application. Each panelist made an absolute evaluation according to the following criteria, and the average of the scores of all the panels was then judged according to the following criteria. <Absolute evaluation criteria> (Score): (Evaluation) 5: Very good 4: Fairly good 3: Neither good nor bad 2: Fairly bad 1: Very bad <Judgment criteria> (Judgment): (Average score) AA: Average score is 4.5 or more and 5.0 or less A: Average score is 4.0 or more and less than 4.5 B: Average score is 3.5 or more and less than 4.0 C: Average score is 2.5 or more and less than 3.5 D: Average score is less than 2.5

[0091] As shown in the results in Tables 1 to 3, Examples 1 to 31 and 37 to 43 of the present invention were excellent in all aspects. On the other hand, among Comparative Examples 1 to 9 shown in the results in Table 4, Comparative Example 1, in which component (B) was increased instead of component (A), was unsatisfactory in terms of "moisturizing feeling" and "reduction in the visibility of wrinkles and unevenness." Comparative Examples 2 and 3, in which silicone wax was used instead of component (A), were unsatisfactory in terms of "reduction in the visibility of wrinkles and unevenness" and "dispersibility of color pigment." Comparative Example 4, which did not contain component (E), was unsatisfactory in terms of "maintenance of cosmetic film," "reduction in the visibility of wrinkles and unevenness," and "dispersibility of color pigment." Comparative Examples 5 and 6, which did not contain component (E) but instead contained another silicone resin, were unsatisfactory in terms of "dispersibility of color pigment." Comparative Example 7, which did not contain component (E) but instead contained another rosin acid resin, was unsatisfactory in terms of "reduction in the visibility of wrinkles and unevenness" and "dispersibility of color pigment." Furthermore, Comparative Example 8, which did not contain component (C), was unsatisfactory in terms of "cosmetic film retention" and "color pigment dispersibility." Comparative Example 9, which did not contain component (D), was inferior in terms of "wrinkle and unevenness inconspicuousness." Comparative Example 10, which was outside the lower limit of the component (A) / (E) ratio, was inferior in terms of "moisturizing feel" and "wrinkle and unevenness inconspicuousness," while Comparative Example 11, which was outside the upper limit of the component (A) / (E) ratio, was inferior in terms of "cosmetic film retention," "wrinkle and unevenness inconspicuousness," and "color pigment dispersibility."
