     TECHNICAL FIELD 
     The present invention relates to an oil-in-water emulsion composition providing watery and non-sticky feeling upon use and imparting excellent skin roughness-covering effect and its persistency, firmness/elasticity, smoothness, moist feeling and shiny appearance to the skin. 
     BACKGROUND ART 
     Up to the present, making the skin pretty and helping makeup last longer have been carried out by smoothening irregularities in the skin due to e.g. pores and fine wrinkles. 
     As the skin cosmetics for use in such treatment, for example, aqueous gel cosmetics containing a silica-coated silicone elastomer and an associative thickening agent have been proposed (Patent document 1). The cosmetics have a roughness-covering effect and can be overlaid on a foundation as well as imparting firmness/elasticity to the skin. However, the aqueous gel cosmetics contain no oil contents. Because of this, sense of use including moist feeling and shiny appearance is unsatisfactory and persistency of roughness-covering effect tends to be inferior. Furthermore, since the cosmetics are developed for the purpose of overlaying on a foundation, formulation ingredients and contents are limited, and it is difficult to obtain satisfactory roughness-covering effect and sense of use (firmness/elasticity, smoothness, moist feeling, and shiny appearance).

     DETAILED DESCRIPTION 
     The oil-in-water emulsion composition of the present invention is characterized by comprising (A) a non-emulsifying crosslinked polymethylsiloxane comprising (a1) a dimethicone cross polymer and (a2) a non-emulsifying crosslinked polymethylsiloxane except the dimethicone cross polymer, (B) an associative thickening agent, (C) a polyether-modified silicone, (D) a silicone oil and (E) water in a predetermined ratio. Now, the present invention will be more specifically described below. 
     &lt;(A) Non-Emulsifying Crosslinked Polymethylsiloxane&gt; 
     The non-emulsifying crosslinked polymethylsiloxane (A) to be used in the present invention is a combination of at least two types of components, i.e., (a1) a dimethicone cross polymer and (a2) a non-emulsifying crosslinked polymethylsiloxane except the dimethicone cross polymer. 
     (a1) Dimethicone Cross Polymer 
     The dimethicone cross polymer (a1) to be used in the present invention refers to a dimethicone cross polymer (the INCI nomenclature) obtained by a crosslinking reaction between an organohydrogensiloxane and an alkene. 
     The dimethicone cross polymer (a1) is preferably blended in a swollen state with a low-viscosity oil, particularly, a linear or cyclic silicone oil. Examples of commercially available dimethicone cross polymers in a swollen state include products available from Dow Corning Toray Co., Ltd., such as “DC9040” (trade name) which is a mixture of a dimethicone cross polymer and decamethylcyclopentasiloxane (the actual quantity of the cross polymer: 12%), “DC9041” (trade name) which is a mixture of a dimethicone cross polymer and dimethicone mPa·s (the actual quantity of the cross polymer: 16%), and “DC9045” (trade name) which is a mixture of a dimethicone cross polymer and a decamethylcyclopentasiloxane (the actual quantity of the cross polymer: 12.5%). Of them, “DC9041” (trade name) is particularly preferred since it provides excellent roughness-covering effect immediately after application and provides excellent feeling upon use, i.e., less sticky, smooth and silky feeling. 
     (a2) Non-Emulsifying Crosslinked Polymethylsiloxane Except the Dimethicone Cross Polymer 
     The non-emulsifying crosslinked polymethylsiloxane (a2) except the dimethicone cross polymer to be used in the present invention refers to one or two or more selected from the group consisting of a dimethicone/vinyldimethicone cross polymer (INCI nomenclature), which is obtained by a crosslinking reaction between an organohydrogensiloxane and vinyldimethylsiloxane; a dimethicone/phenylvinyldimethicone cross polymer (INCI nomenclature) (also called “polysilicone-11”), which is obtained by a crosslinking reaction between an organohydrogensiloxane and phenylvinyldimethylsiloxane; and a vinyldimethicone/lauryldimethicone cross polymer (INCI nomenclature), which is obtained by a crosslinking reaction between a laurylorganohydrogensiloxane and vinyldimethylsiloxane. 
     The non-emulsifying crosslinked polymethylsiloxane (a2) except the dimethicone cross polymer is preferably blended in a swollen state with a low viscosity oil, particularly, a linear or cyclic silicone oil. Examples of such a swollen product include commercially available products from Shin-Etsu Chemical Co., Ltd., such as “KSG-15” (trade name), which is a mixture of a dimethicone/vinyldimethicone cross polymer and a cyclopentasiloxane (actual quantity: about 5%), “KSG-16” (trade name), which is a mixture of a dimethicone/vinyldimethicone cross polymer and dimethicone 6 mPa·s (actual quantity: about 25%), “KSG-18” (trade name), which is a mixture of a dimethicone/phenylvinyldimethicone cross polymer and phenyltrimethicone (actual quantity: about 15%), “KSG-41” (trade name), which is a mixture of a vinyldimethicone/lauryldimethicone cross polymer and liquid paraffin (actual quantity: about 30%), “KSG-42” (trade name), which is a mixture of a vinyldimethicone/lauryldimethicone cross polymer and light isoparaffin (actual quantity: about 25%), “KSG-43” (trade name), which is a mixture of a vinyldimethicone/lauryldimethicone cross polymer and glyceryl tri(2-ethylhexanoate) (actual quantity: about 30%), and “KSG-44” (trade name), which is a mixture of a vinyldimethicone/lauryldimethicone cross polymer and squalane (actual quantity: about 5%); and commercially available products from GRANT such as “GRANSIL GCM” (trade name), which is a mixture of polysilicone-11 and octamethylcyclotetrasiloxane (actual quantity: about 6%), “GRANSIL GCM-5” (trade name), which is a mixture of polysilicone-11 and decamethylcyclopentasiloxane (actual quantity: about 6%), “GRANSIL IDS” (trade name), which is a mixture of polysilicone-11 and isodecane (actual quantity: about 7%), “GRANSIL DMG-6” (trade name), which is a mixture of polysilicone-11 and dimethicone 6 mPa·s (actual quantity: about 18%), “GRANSIL DMG-20” (trade name), which is a mixture of polysilicone-11 and dimethicone 20 mPa·s (actual quantity: about 25%), “GRANSIL DMG-50” (trade name), which is a mixture of polysilicone-11 and dimethicone 50 mPa·s (actual quantity: about 26%), “GRANSIL PM” (trade name), which is a mixture of polysilicone-11 and phenyltrimethicone (actual quantity: about 20%), and “GRANSIL ININ” (trade name), which is a mixture of polysilicone-11 and isononyl isononanoate (actual quantity: about 15%). Of them “KSG-18” (trade name) is particularly preferred since it has excellent persistency of a roughness-covering effect and provides excellent moist feeling and shiny appearance. 
     Mass Ratio of (a1) and (a2) 
     The mass ratio ((a2)/(a1)), which is a mass ratio of the non-emulsifying crosslinked polymethylsiloxane (a2) except the dimethicone cross polymer relative to the dimethicone cross polymer (a1), falls within the range of 0.1 to 2.5, preferably 0.1 to 1.5 and further preferably 0.2 to 1.0. The mass ratio herein refers to the mass ratio of actual contents of crosslinked polymers. If the mass ratio is less than 0.1, persistency of a roughness-covering effect, moist feeling and shiny appearance after application cannot be sufficiently obtained. In contrast, if the mass ratio exceeds 2.5, the roughness-covering effect and smoothness immediately after application cannot be sufficiently obtained. 
     Content of (A) Non-Emulsifying Crosslinked Polymethylsiloxane 
     The content of non-emulsifying crosslinked polymethylsiloxane (A) (total of actual contents of (a1) and (a2)) is 0.5 to 5.0 mass %, preferably 1.0 to 3.0 mass % and further preferably 1.5 to 2.5 mass % relative to the total amount of the oil-in-water emulsion composition. If the content is less than 0.5 mass %, the roughness-covering effect is not sufficiently obtained and smoothness, moist feeling and shiny appearance after application are not sufficiently obtained, either. In contrast, if the content exceeds 5.0 mass %, the roughness-covering effect is not enhanced and the resultant composition becomes sticky. Because of this, sense of use tends to be damaged. 
     &lt;(B) Associative Thickening Agent&gt; 
     The associative thickening agent (B) to be used in the present invention is a hydrophobically modified polyether urethane represented by the following general formula:
 
R 1 —{(O—R 2 ) k —OCONH—R 3 [—NHCOO—(R 4 —O) n —R 5 ] h } m  
 
wherein R 1 , R 2  and R 4  may be the same or different and represent a hydrocarbon group; R 3  represents a hydrocarbon group that may have a urethane bond; R 5  represents a linear or branched divalent hydrocarbon group; m is an integer of 2 or more; h is an integer of 1 or more; and k and n are each independently an integer of 0 to 1000.
 
     Association network is established by blending an associative thickening agent to enhance the viscosity of an aqueous system. 
     Examples of commercially available products of the hydrophobically modified polyether urethane include products from ADEKA Corporation such as “ADEKA NOL GT-700” (trade name) (PEG-240/decyltetradeceth-20/hexamethyldiisocyanate copolymer). 
     The associative thickening agent (B) is blended in an amount of 0.5 to 5.0 mass %, preferably 1.0 to 3.0 mass % and further preferably 1.2 to 2.0 mass % relative to the total amount of the oil-in-water emulsion composition. If the content is less than 0.5 mass %, a sufficient viscosity cannot be obtained and firmness/elasticity deteriorates. In contrast, if the content exceeds 5.0 mass %, viscosity increases, the resultant composition becomes sticky. Because of this, sense of use tends to be damaged. 
     &lt;(C) Polyether-Modified Silicone&gt; 
     The polyether-modified silicone (C) to be used in the present invention is a compound represented by the following general formula (1): 
                                
wherein A represents an alkyl group having 1 to 6 carbon atoms, a phenyl group or B (described later); B is a polyoxyalkylene group represented by the general formula: —C 3 H 6 O(C 2 H 4 O) a (C 3 H 6 O) b R′ where R′ is a group selected from the group consisting of a hydrogen atom, an acyl group and an alkyl group having 1 to 6 carbon atoms; a is an integer of 0 to 50, b is an integer of 0 to 50, with the proviso that a and b are not simultaneously 0; R is each independently an alkyl group having 1 to 6 carbon atoms or a phenyl group; m is an integer of 50 to 1000, and n is an integer of 0 to 50, with the proviso that at least one polyoxyalkylene group is present in a molecule. In the above, n is preferably at least 1 and R preferably represents a methyl group.
 
     Particularly preferable examples of the polyether-modified silicone (C) to be used in the present invention include commercially available products from Shin-Etsu Chemical Co., Ltd. such as “KF-6017” (trade name) and “KF-6028” (trade name). 
     The polyether-modified silicone (C) is blended in an amount of 0.5 to 5.0 mass %, preferably 0.5 to 3.0 mass % and further preferably 0.5 to 1.5 mass % relative to the total amount of the oil-in-water emulsion composition. If the content is less than 0.5 mass %, dispersibility and aggregation inhibition of the non-emulsifying crosslinked polymethylsiloxane (A) sometimes become insufficient. In contrast, if the content exceeds 5.0 mass %, the resultant composition becomes sticky. Because of this, sense of use tends to be damaged. 
     &lt;(D) Silicone Oil&gt; 
     The silicone oil (D) to be used in the present invention can be selected from a wide range of silicon oils generally used in cosmetics and put in use. Specific examples thereof include, but not limited to, linear or cyclic silicones such as methylpolysiloxane, octamethylsiloxane, decamethyltetrasiloxane, methylhydrogenpolysiloxane, methylphenyl polysiloxane, hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane and decamethyl cyclopentasiloxane. These can be used alone or in combination with two or more. 
     The silicone oil (D) is blended in an amount of 3.0 to 30 mass %, preferably 5.0 to 30 mass % and further preferably 10 to 25 mass % relative to the total amount of the oil-in-water emulsion composition. If the content is less than 3.0 mass %, dispersion of the non-emulsifying crosslinked polymethylsiloxane (A) sometimes becomes insufficient. In contrast, if the content exceeds 30 mass %, sense of use and stability of a preparation tend to be damaged. 
     &lt;(E) Water&gt; 
     The water (E) to be used in the present invention may be distilled water, ion-exchanged water or purified water. The water (E) is blended sufficiently enough to allow the total amount of the oil-in-water emulsion composition to reach 100%. 
     The oil-in-water emulsion composition according to the present invention, if necessary, may appropriately contain various types of components that are usually contained in cosmetics and quasi-drugs, as long as the effect of the present invention is not damaged. Examples of the components include a powder component, a solid fat and oil, a moisturizer, a thickening agent, a sequestering agent, a pigment, a pH moderator, a skin nutritional supplement, vitamins, an antiseptic, an antioxidant, an antioxidation aid and a fragrance. 
     Particularly, as the thickening agent, a water-soluble thickening agent can be blended other than the above associative thickening agent (B). Examples of the water-soluble thickening agent include plant-derived polymers such as Arabian gum, gum tragacanth, galactan, guar gum, carrageenan, pectin, a Quince Seed ( PYRUS CYDONIA  SEED) extract and brown alga powder; microbe-derived polymers such as xanthan gum, dextran, pullulan and succinoglycan; animal-derived polymers such as collagen, casein, albumin and gelatin; starches such as carboxymethyl starch and methylhydroxy starch; celluloses such as methylcellulose, nitrocellulose, ethylcellulose, methylhydroxypropylcellulose, hydroxyethylcellulose, cellulose sulfate, hydroxypropylcellulose, carboxymethylcellulose, crystalline cellulose and cellulose powder; vinyl polymers such as polyvinyl alcohol, polyvinyl methyl ether, polyvinylpyrrolidone and a carboxyvinyl polymer; and acrylic polymers such as a polyacrylic acid and a salt thereof, a polyacrylic imide and a dimethylacrylamide/sodium acryloyldimethyl taurine cross polymer. Other than these, e.g. glycyrrhizinic acid, alginic acid and a salt thereof are included. In addition, inorganic thickening agents such as bentonite, laponite, hectorite, magnesium aluminum silicate and silicic anhydride can be used. 
     The oil-in-water emulsion composition according to the present invention can be produced in accordance with the method traditionally being used in the art for producing an emulsion. More specifically, the oil-in-water emulsion composition can be produced by preparing an oil phase component and a water phase component separately, and mixing and emulsifying the water phase and the oil phase by means of a disperser or a homogenizer.

     In Table 1, the following products were used as A (a1, a2), B, C components. 
     (5) C component: “KF-6028” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (8) a1 component: “DC9041” (trade name) manufactured by Dow Corning Toray Co., Ltd. 
     (9) a2 component: “KSG-18” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (10) B component: “ADEKA NOL GT-700” (trade name) manufactured by ADEKA Corporation. 
     In the columns of component a1 and a2, the content of the product is shown and the actual quantity of a crosslinked polymer contained in the product is shown within parentheses. 
     As is apparent from Table 1, in the cases (Comparative Examples 1 to 4 and 7) where none or only one of the two types (a1, a2) of (A) non-emulsifying crosslinked polymethylsiloxanes is contained and in the cases (Comparative Examples 5 and 6) where the mass ratio ((a2)/(a1)) is outside the range of 0.1 to 2.5 even if both of these are contained, the roughness-covering effect and/or its persistency were insufficient. In contrast, in the cases (Examples 1 and 2) where these components are contained such that the mass ratio ((a2)/(a1)) falls within the range of 0.1 to 2.5, the roughness-covering effect and its persistency were sufficiently obtained; at the same time, satisfactory results were obtained with respect to sense of use including smoothness, moist feeling, shiny appearance after application and non-stickiness. 
     &lt;Evaluation on Content of (C) Polyether-Modified Silicone&gt; 
     Oil-in-water emulsion compositions (test samples) were prepared in accordance with the formulations shown in the following Table 2 and individual properties were evaluated in accordance with the above evaluation methods. The results are also shown in Table 2.

     In Table 2, the following products were used as A (a1, a2), B, C components. 
     (5) C component: “KF-6028” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (8) a1 component: “DC9041” (trade name) manufactured by Dow Corning Toray Co., Ltd. 
     (9) a2 component: “KSG-18” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (10) B component: “ADEKA NOL GT-700” (trade name) manufactured by ADEKA Corporation. 
     In the columns of component a1 and a2, the content of the product is shown and the actual quantity of a crosslinked polymer contained in the product is shown within parentheses. 
     As is apparent from Table 2, in the cases (Comparative Examples 8 and 9) where the content of (C) a polyether-modified silicone is less than 0.5 mass %, the dispersibility of (A) a non-emulsifying crosslinked polymethylsiloxane at the time of manufacturing was poor and aggregation of (A) the non-emulsifying crosslinked polymethylsiloxane with time was observed. Furthermore, in the case (Comparative Example 10) where the content of (C) a polyether-modified silicone exceeds 5.0 mass %, the composition became sticky. In contrast, in the cases (Examples 1 and 3) where (C) a polyether-modified silicone was contained within the range of 0.5 to 5.0 mass %, dispersibility of (A) a non-emulsifying crosslinked polymethylsiloxane at the time of manufacturing was satisfactory and aggregation with time was suppressed and sense of use was satisfactory without stickiness. 
     &lt;Evaluation on Content of (B) Associative Thickening Agent&gt; 
     Oil-in-water emulsion compositions (test samples) were prepared in accordance with the formulations shown in the following Table 3 and individual properties were evaluated in accordance with the above evaluation methods. The results are also shown in Table 3.

     In Table 3, the following products were used as A (a1, a2), B, C components. 
     (5) C component: “KF-6028” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (8) a1 component: “DC9041” (trade name) manufactured by Dow Corning Toray Co., Ltd. 
     (9) a2 component: “KSG-18” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (10) B component: “ADEKA NOL GT-700” (trade name) manufactured by ADEKA Corporation. 
     In the columns of component a1 and a2, the content of the product is shown and the actual quantity of a crosslinked polymer contained in the product is shown within parentheses. 
     As is apparent from Table 3, in the cases (Comparative Examples 11 and 12) where the content of (B) an associative thickening agent was less than 0.5 mass %, viscosity was low, stability over time was poor and no firmness/elasticity was felt. Furthermore, in the case (Comparative Example 13) where the content of (B) an associative thickening agent exceeded 5.0 mass %, the resultant composition became sticky. In contrast, in the cases (Examples 4 and 5) where the content of (B) an associative thickening agent fell within the range of 0.5 to 5.0 mass %, the composition had appropriate viscosity and excellent stability over time and provided firmness/elasticity and satisfactory sense of use without stickiness. 
     &lt;Comparison with Cosmetics Containing Silica-Coated Silicone Elastomer&gt; 
     Oil-in-water emulsion compositions (test samples) were prepared in accordance with the formulations shown in the following Table 4 and individual properties were evaluated in accordance with the above evaluation methods. The results are also shown in Table 4.

     In Table 4, the following products were used as A (a1, a2), B, C components and succinoglycan. 
     (5) C component: “KF-6028” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (6) C component: “KF-6017” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (10) a1 component: “DC9041” (trade name) manufactured by Dow Corning Toray Co., Ltd. 
     (11) a2 component: “KSG-18” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (12) a2 component: “GRANSIL DMG-6” (trade name) manufactured by GRANT. 
     (13) a2 component: “KSG-41” (trade name) manufactured by Shin-Etsu Chemical Co., Ltd. 
     (14) a2 component: “9701 COSMETIC POWDER” (trade name) manufactured by Dow Corning Toray Co., Ltd. 
     (15) B component: “ADEKA NOL GT-700” (trade name) manufactured by ADEKA Corporation. 
     (16) Succinoglycan (water-soluble thickening agent): “Rheozan SH” (trade name) manufactured by RHODIA. 
     Furthermore, in the columns of component a1 and a2, the content of the product is shown and the actual quantity of a crosslinked polymer contained in the product is shown within parentheses. 
     As is apparent from Table 4, in compositions (Comparative Examples 14 to 17) containing a silica-coated silicone elastomer but not containing (a1) a dimethicone cross polymer, (C) a polyether-modified silicone and (D) a silicone oil, and described in Patent document 1, roughness-covering effect and its persistency tended to deteriorate. This type of composition can overlay on a foundation for reapplying makeup due to the absence of an oil content; however sense of use such as smoothness, shiny appearance and moist feeling tended to deteriorate. In contrast, compositions (Examples 1 to 8) containing (A) a non-emulsifying crosslinked polymethylsiloxane, (B) an associative thickening agent, (C) a polyether-modified silicone, (D) a silicone oil and (E) water in a predetermined ratio showed excellent evaluation results with respect to either one of the roughness-covering effect and the sense of use.

[Process]
 
     Components (1) to (4) and (11) to (15) were homogeneously mixed and dissolved/dispersed in an aqueous phase. To the aqueous phase, an oil phase, in which components (5) to (9), (17), and (18) were homogeneously dispersed, was gradually added and emulsified by a disper or a homogenizer. Subsequently, a component (16) was added, and a solution, which is prepared by dissolving a component (10) heated in a small amount of component (3), is added and homogeneously dispersed by a disper or a homogenizer.
