Description

Technical Field

[0001] The present invention relates to an oil-in-water type emulsified cosmetic.

Background Art

[0002] Oil-in-water type emulsified cosmetics are widely used in basic cosmetics such as lotions, milks, essences, creams, sunscreen products, foundations, makeup bases, etc. Since the continuous phase of oil-in-water type emulsified cosmetics is water, they are generally excellent in terms of the fresh feeling derived from aqueous components and spreadability. On the other hand, when containing powders such as metal oxides, oil-in-water type emulsified cosmetics have problems such as no color change during application, color uniformity of the coating film, a feeling without powderiness, and inferior moisturizing feeling.

[0003] Regarding such problems, many techniques have been proposed in the past. For example, by containing specific amounts of trimethylsiloxysilicate, a polyacrylamide compound, a hydrophobically treated colored pigment, and a specific spherical powder respectively, even on rough skin, it does not become powdery and a smooth finish can be obtained, and a technique for obtaining an oil-in-water type emulsified cosmetic with sufficient covering power against color unevenness is disclosed (see, for example, Patent Document 1). In addition, a technique has also been proposed in which a cosmetic containing a specific crosslinked organic silicon resin has good usability, good makeup retention, good elongation and finish, and excellent abrasion resistance. (See, for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the prior art, even if a powdery texture and a smooth finish could be achieved, the color change during application and the color uniformity of the coating film were insufficient.

[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 changed within the scope of the present invention. In this specification, "~" means a range including the numerical values before and after it. Further, the "average particle diameter" in the present invention is the value of the median diameter (D50) obtained by measurement using an image analyzer (Luzex AP, manufactured by Nireco Corporation). In the case of an asymmetric shape, in the present invention, the value of the median diameter (D50) obtained from the distribution of the largest particle diameter is used as the average particle diameter. Further, in the present invention, the component name may be described by the cosmetic display name or the International Nomenclature of Cosmetic Ingredient (INCI). When the cosmetic display name and INCI correspond, the English description may be omitted.

[0010] [Component (A)] Hereinafter, Component (A) in the present invention will be described in detail. Component (A) is a crosslinked organosilicon resin which is an addition reaction product of the following (X) component and (Y) component, and is a crosslinked organosilicon resin in which the amount of hydrogen gas generated per mass from this crosslinked organosilicon resin is 1.5 mL / g or less under standard conditions.

[0011] [(X) Component] The (X) component of the present invention is an alkenyl group-containing organosilicon resin represented by the following average compositional formula (1) and having one or more alkenyl groups in one molecule, and can be used alone or in combination of two or more. [Chemical Formula 5] JPEG2025090556000005.jpg8153[wherein, R 1 are each independently an alkenyl group having 2 to 8 carbon atoms, and R 2 are 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. R 3 are each independently an organopolysiloxane-containing group and a group selected from the above R 2 ; and at least one of R 3 in each R 1 / 2 3SiO 3 unit is an organopolysiloxane-containing group. a1, a2, a3, b, c, and d are numbers such that 0 < a1 ≤ 5, 0 < a2 ≤ 400, 0 ≤ a3 ≤ 400, 0 ≤ b ≤ 320, 0 ≤ c ≤ 320, 0 < d ≤ 1,000, and satisfy 0.5 ≤ (a1 + a2 + a3) / d ≤ 1.5.]

[0012] [(Y) Component] The (Y) component of the present invention is an organohydrogenpolysiloxane represented by the following average compositional formula (2) and having two or more hydrosilyl groups in one molecule, and can be used alone or in combination of two or more. The addition reaction amount is an amount such that the amount of hydrosilyl groups is 0.5 to 1.2 moles with respect to 1 mole of the amount of alkenyl groups in the above (X) component, preferably 0.5 to 1.2 moles, more preferably 0.8 to 1.2, and even more preferably 0.9 to 1.1. [Chemical Formula 6] JPEG2025090556000006.jpg8153[wherein, R 2 is the same as above, and R 4 are each independently a hydrogen atom or a group represented by the above R 2 ; and two or more of all R 4 are hydrogen atoms; e, f, g, and h are 0 or positive numbers, provided that 2 ≤ e + f + g + h < 32 is satisfied.]

[0013] In the above formula, R 1are, independently of each other, alkenyl groups having 2 to 8 carbon atoms. More specifically, vinyl group, allyl group, isopropenyl group, butenyl group, pentenyl group, hexenyl group, cyclohexenyl group, octenyl group and the like can be mentioned. In particular, vinyl group and allyl group are preferable.

[0014] In the above formula, R 2 are, independently of each other, groups 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 them, an alkyl group, aryl group, aralkyl group, and fluorine-substituted alkyl group having 1 to 10 carbon atoms are preferable. More specifically, methyl group, ethyl group, propyl group, butyl group, pentyl group, cyclopentyl group, cyclohexyl group, phenyl group, tolyl group, etc., trifluoropropyl group and the like can be mentioned. In particular, an alkyl group having 1 to 5 carbon atoms, phenyl group or trifluoropropyl group is preferable. Further, optionally, a part of R 2 may contain one or more groups selected from a hydroxyl group or an alkoxy group having 1 to 8 carbon atoms.

[0015] In the alkenyl group-containing organosilicon resin represented by the above formula (1), a1, a2, a3, b, c, and d satisfy 0 < a1 ≤ 5, preferably 0 < a1 ≤ 4.5, more preferably 1 ≤ a1 ≤ 4, and still more preferably 1 ≤ a1 ≤ 3. When a1 is greater than 5, the possibility of gelation increases and film-forming property is lacking. 0 ≤ a2 ≤ 400, preferably 0 ≤ a2 ≤ 100, more preferably 0 ≤ a2 ≤ 50. 0 ≤ a3 ≤ 400, preferably 0 ≤ a3 ≤ 100, more preferably 0 ≤ a3 ≤ 50. When a3 is greater than 400, the melting point of the resin becomes low and film-forming property is lacking. 0 ≤ b ≤ 320, 0 ≤ c ≤ 320, and b = 0 and c = 0 are preferable. 0 < d ≤ 1,000, and it is a number satisfying 0.5 ≤ (a1 + a2 + a3) / d ≤ 1.5, preferably a number satisfying 0.7 ≤ (a1 + a2 + a3) / d ≤ 1.2. When the value of (a1 + a2 + a3) / d is less than the above lower limit, the crosslinking degree increases and the molecular weight becomes large, resulting in a gel state. When it exceeds the above upper limit, the molecular weight becomes small and film-forming property is lacking.

[0016] The alkenyl group-containing organosilicon resin represented by the above formula (1) has a Q unit (SiO 4 / 2 ), an M unit (R 2 3SiO 1 / 2 and R 1 R 2 2SiO 1 / 2 ) as an essential structure, and a D unit (R 2 2SiO 2 / 2 ), a T unit (R 2 SiO 3 / 2 ) as an optional structure. It may be in a solid state or a liquid state at 25°C, but a solid state is preferred from the viewpoint of film-forming properties. For example, MQ resin, MTQ resin, MDQ resin, MDTQ resin can be mentioned. Its weight average molecular weight 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 viewpoints of performance and workability such as filtration. The weight average molecular weight can be determined as the weight average molecular weight in terms of polystyrene in gel permeation chromatography (GPC) analysis.

[0017] In the organohydrogenpolysiloxane having two or more hydrosilyl groups in one molecule represented by the above formula (2), R 4 are each independently a monovalent hydrocarbon group having no aliphatic unsaturated bond and having 1 to 30 carbon atoms, and two or more of all R 4 are hydrogen atoms.

[0018] In the above formula (2), e, f, g, h are 0 or positive numbers, and may be selected so as to satisfy 2 ≤ e + f + g + h < 32. Preferably g = 0 and h = 0, more preferably e = 2, 0 ≤ f < 30, g = 0, h = 0, and even more preferably e = 2, 0 ≤ f ≤ 20, g = 0, h = 0. If the number of silicon atoms contained in the (Y) component is 32 or more, the crosslinked organosilicon resin is likely to gel due to holding the solvent, and thus is likely to form a sticky film after the solvent volatilizes. If the number of silicon atoms contained in the (Y) component is less than 32, the crosslinked organosilicon resin is likely to dissolve in the solvent and thus is likely to be in a liquid state. Therefore, it is easy to obtain a non-sticky film after the solvent volatilizes.

[0019] Said R 3 is, independently of one another, an organopolysiloxane-containing group, or a group selected from said R 2 . Examples of the organopolysiloxane-containing group include groups represented by the following general formulas (3) to (6). R 3 3SiO 1 / 2 In each of the units, one or more R 3 are organopolysiloxane-containing groups. Optionally, a part of R 3 may be a hydroxyl group. [Chemical Formula 7] JPEG2025090556000007.jpg34153(In the formula, R 2 is the same as above, n and i are integers satisfying 0 ≦ n ≦ 5 and 0 ≦ i ≦ 500, and j1 to j3 are each an integer of 0 or more and 2 or less.)

[0020] m is an integer of 0 ≦ m ≦ 5, preferably 0 ≦ m ≦ 2, i is an integer of 0 ≦ i ≦ 500, preferably 1 ≦ i ≦ 100, and more preferably 1 ≦ i ≦ 50. When i is greater than 500, the melting point of the resin becomes low, resulting in a lack of film-forming properties. j1 to j3 are each an integer of 0 or more and 2 or less.

[0021] 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 a D unit or a T unit, and is composed only of an M unit and a Q unit. By using an alkenyl group-containing organosilicon resin that does not contain a D unit or a T unit as a raw material, the crosslinked organosilicon resin that is an addition reaction product can form a strong film.

[0022] 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 a T unit and a Q unit, and becomes a linear molecule composed only of an M unit and a D unit. By using a linear organohydrogenpolysiloxane as a raw material, the crosslinked organosilicon resin that is an addition reaction product can form a flexible film.

[0023] Also, it may have two or more groups represented by the formula (2). As the chain length of the group represented by the formula (2) increases, it has the effect of imparting flexibility to the organosilicon resin. Therefore, for example, by including two types of groups represented by the formula (2) having different chain lengths, the film physical properties can be controlled.

[0024] [Physical Properties of Crosslinked Organosilicon Resin] The weight average molecular weight of the crosslinked organosilicon resin of the present invention is preferably from 5,000 to 1,000,000, more preferably from 8,000 to 500,000, and even more preferably from 10,000 to 500,000. Being within such a range is more preferable in terms of performance and workability such as filtration. The weight average molecular weight can be determined as the weight average molecular weight in terms of polystyrene in gel permeation chromatography (GPC) analysis (hereinafter the same).

[0025] The crosslinked organosilicon resin may be in a solid state, a gel state, or a liquid state at 25°C. For example, it can be dissolved in a liquid oil agent and volatilized to easily form a film. This film is a brittle and strong film before crosslinking, but after crosslinking, its brittleness is improved, and a non-sticky and flexible film can be obtained. From the viewpoint of film formability, a solid state or a gel state is preferable, and a solid state is more preferable. The 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) and drying it at 105°C for 3 hours to see if a self-supporting film is formed. If a film is not formed, oil will seep out due to cracks in the film and the oil resistance will be significantly reduced, and the followability with the skin will be low, resulting in an unnatural finish.

[0026] The crosslinked organosilicon resin of the present invention can be more preferably used as a film-forming agent. The organosilicon resin before crosslinking forms a brittle and strong film, while the crosslinked organosilicon resin after crosslinking has improved brittleness and forms a non-sticky and flexible film. This is because the organosilicon resin before crosslinking forms a strong film, but by crosslinking with flexible chains, flexibility is imparted to the film. Generally, a hard film has low flexibility, and a film with high flexibility tends to be soft, so the strength and flexibility of the film have been considered to be in an antinomic relationship. However, the crosslinked organosilicon resin of the present invention has the characteristic of excellent followability due to its high flexibility despite forming a strong film.

[0027] In addition, the film formed from the crosslinked organosilicon resin has significantly improved oil resistance against oil agents such as sebum compared to the film formed from the organosilicon resin before crosslinking. Although the oil resistance of the organosilicon resin tends to improve with an increase in molecular weight, since there is a limit to increasing the molecular weight of the organosilicon resin, the oil resistance also has a limit. Crosslinking of the organosilicon resin with a crosslinking agent leads to a pseudo-increase in the molecular weight of the organosilicon resin, so it has the effect of raising that limit point. Therefore, the crosslinked organosilicon resin has oil resistance that cannot be achieved with conventional organosilicon resins.

[0028] The crosslinked organosilicon resin in which f in the above formula (2) is an integer satisfying 0 < f < 30 is in a solid state at 25°C, and a crosslinked organosilicon resin particularly excellent in film-forming properties can be obtained.

[0029] In addition, when f in the above formula (2) satisfies 0 ≤ f < 30 and two of R 4 are hydrogen atoms, the crosslinked organosilicon resin is in a solid state at 25°C, and a crosslinked organosilicon resin particularly excellent in film-forming properties can be obtained. When f is 30 or more, or when three or more of R 4 are hydrogen atoms, there is a high possibility of becoming gel-like when the diluting solvent is removed. In this case, although it has film-forming properties, it has a feeling derived from the gel.

[0030] In the above formula (1), a1 satisfies 0 < a1 ≤ 3, f in the above formula (2) satisfies 0 ≤ f < 20, and R 4 Among them, the crosslinked organosilicon resin in which two of them are hydrogen atoms is in a solid state at 25°C, and a crosslinked organosilicon resin with particularly excellent film-forming properties can be obtained. The obtained film exhibits particularly excellent flexural resistance and oil resistance.

[0031] The amount of hydrogen gas generated per mass of the above crosslinked organosilicon resin is 1.5 mL / g or less under standard conditions. If it exceeds 1.5 mL / g, the generation of hydrogen gas over time, or the reaction of remaining hydroxy groups, alkoxy groups with hydrosilyl groups, may increase the possibility of thickening over time and deteriorate the stability over time. The generation amount of hydrogen gas is preferably 0.01 - 1.2 mL / g, more preferably 0.02 - 1.0 mL / g.

[0032] The amount of hydrogen gas per mass can be calculated from the volume of hydrogen gas generated by the reaction of hydrosilyl groups and bases. For example, the following method can be mentioned, but the calculation method is not limited to this. <Measurement method of hydrogen gas amount> 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, 10 g of a 20% by mass aqueous sodium hydroxide solution is added dropwise. The volume of the generated hydrogen gas is divided by the pure content of the crosslinked organosilicon resin to obtain the amount of hydrogen gas per mass.

[0033] [Manufacturing method] The crosslinked organosilicon resin can be synthesized by various formulations known in the art. For example, crosslinking can be achieved by reacting an organopolysiloxane having hydroxyl groups at both ends with the surface silanol groups of the organosilicon resin. However, since it is difficult to completely control the amount of silanol groups on the surface of the organosilicon resin, there is a problem that it is difficult to accurately control the amount of the organopolysiloxane to be crosslinked. In addition, it can be synthesized by an addition reaction between an organosilicon resin having a hydrosilyl group and an organopolysiloxane having alkenyl groups at both ends. However, the hydrosilyl groups in the organosilicon resin have low reactivity, and there is a problem that the remaining hydrosilyl groups react over time, resulting in an increase in viscosity and the generation of hydrogen gas. Therefore, as a method for producing a crosslinked organosilicon resin crosslinked with silicone, a synthesis method by an addition reaction between an organosilicon resin having an alkenyl group and an organopolysiloxane having hydrosilyl groups at both ends is preferred.

[0034] The method for producing the crosslinked organosilicon resin by the above hydrosilylation reaction will be described in more detail below. In the hydrosilylation reaction step of the alkenyl group-containing organosilicon resin represented by the above average composition formula (1) and the organohydrogenpolysiloxane represented by the above formula (2), the molar ratio of the terminal hydrosilyl group / unsaturated group can be selected from the range of 0.5 to 2.0, preferably 0.5 to 1.2 moles, more preferably 0.8 to 1.2, and even more preferably 0.9 to 1.1. If the above ratio is too large, the remaining amount of hydrosilyl groups will increase, and the stability over time may deteriorate.

[0035] This hydrosilylation reaction is preferably carried out in the presence of a platinum catalyst or a rhodium catalyst. For example, chloroplatinic acid, alcohol-modified chloroplatinic acid, chloroplatinic acid-vinylsiloxane complex, etc. are preferred. In addition, if the amount of the catalyst used is excessive, the sample will be colored, so the amount of platinum or rhodium is preferably 50 ppm or less, and more preferably 20 ppm or less.

[0036] Furthermore, the 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 methyltrimethicone 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. Ethanol, 1-propanol, and 2-propanol are particularly preferred from the viewpoint of reactivity.

[0037] 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). When within the above range, the reaction system is uniformly maintained and the reaction proceeds efficiently.

[0038] The crosslinked organic silicon resin of component (A) 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 it is, or may be replaced after the addition reaction, and an organic solvent for replacement can be selected according to the application. The replacement solvent is not particularly limited and can be selected from the aforementioned organic solvents.

[0039] The addition reaction conditions are not particularly limited, but it is preferable to heat at a temperature of 50 to 150°C, more preferably 80 to 120°C, for about 1 to 10 hours under reflux.

[0040] It is also possible to include a step of removing the rhodium catalyst or platinum catalyst used after the addition reaction with activated carbon. The amount of activated carbon used is preferably 0.001 to 5.0% by mass, more preferably 0.01 to 1.0% by mass, based on the whole system. When within the above range, coloring of the sample can be more suppressed.

[0041] After the addition reaction, it is possible to include a step of removing the remaining hydrosilyl groups as necessary. Especially when used in applications such as cosmetics, the hydrosilyl groups may be deactivated by dehydrogenation reaction over time. Since hydrogen gas is generated, there is no problem from the viewpoint of safety, so it is preferable to include a step of removing the hydrosilyl groups.

[0042] Examples of the step of removing the hydrosilyl groups include a formulation in which a basic catalyst is added to hydrolyze the unreacted hydrosilyl groups, and then an acidic catalyst equivalent to the molar equivalent of the basic catalyst is added for neutralization. Examples of the basic catalyst include strong basic catalysts and weak basic catalysts. Examples of the strong basic catalyst include alkali metal hydroxides such as lithium hydroxide, sodium hydroxide, potassium hydroxide, calcium hydroxide, and barium hydroxide. Examples of the weak basic catalyst include alkali metal carbonates such as sodium carbonate and calcium carbonate, and alkali metal hydrogencarbonates such as sodium hydrogencarbonate and potassium hydrogencarbonate. In terms of promoting the dehydrogenation reaction, it is particularly preferable to use a strong basic catalyst, specifically sodium hydroxide. Examples of the acidic catalyst include inorganic acids such as hydrochloric acid, sulfuric acid, sulfurous acid, fuming sulfuric acid, and phosphoric acid, sulfonic acids such as p-toluenesulfonic acid, methanesulfonic acid, and trifluoromethanesulfonic acid, and carboxylic acids such as oxalic acid, formic acid, acetic acid, propionic acid, benzoic acid, citric acid, and trifluoroacetic acid.

[0043] In general, it is preferable to use an acid or a base in combination with water and heat at a temperature below the boiling point of water rather than using the acid or the base alone. By this step, a hydrosilyl group (SiH group) is converted into a hydroxysilyl group (SiOH group). However, when a crosslinked organosilicon resin is treated with a base catalyst, the physical properties change due to the reaction of silanol groups and alkoxy groups in the organosilicon resin. Therefore, it is not preferable to remove the hydrosilyl group by this method.

[0044] The content of component (A) in the present invention is not particularly limited, and is preferably 0.1% or more, more preferably 0.3% or more, and even more preferably 0.5% or more, based on the total amount of the oil-in-water type emulsified cosmetic. Also, it is preferably 10% or less, more preferably 8% or less, and even more preferably 6% or less. Further, 0.1 to 10% is preferable, 0.3 to 8% is more preferable, and 0.5 to 6% is even more preferable. Within this range, it is more preferable because the color change during application, the color uniformity of the coating film, and the moisturizing feeling are more excellent.

[0045] [Component (B)] Component (B) in the present invention is a pigment-grade metal oxide. In the present invention, "pigment-grade" means that the average particle diameter is 0.1 to 3 μm.

[0048] Among these, from the viewpoints of no color change during application and color uniformity of the coating film, one or more selected from the group consisting of polyglycerol fatty acid esters, glycerol fatty acid esters, phospholipids, acyl amino acids, ceramides, and dextrin fatty acid esters are preferred, and one or more selected from the group consisting of polyglyceryl tetraisostearate, polyglyceryl triisostearate, polyglyceryl diisostearate, polyglyceryl monoisostearate, glyceryl tri(caprylate / caprate), lecithin, hydrogenated lecithin, lauroyl lysine, lysine dilauroyl glutamate Na, stearoyl glutamate 2Na, lauroyl aspartic acid Na, cocooyl glutamate 2Na, dextrin palmitate, (palmitic acid / ethylhexanoic acid) dextrin, and dextrin isostearate are more preferred, and one or more selected from the group consisting of polyglyceryl tetraisostearate, lecithin, lysine dilauroyl glutamate Na, stearoyl glutamate 2Na, and lauroyl aspartic acid Na are even more preferred, and polyglyceryl tetraisostearate and lecithin are most preferred.

[0049] In component (B), the treatment amount of the hydrophobizing surface treatment agent is not particularly limited. For example, 0.01% or more is preferred, 0.05% or more is more preferred, and 0.08% or more is even more preferred. Also, 10% or less is preferred, 8% or less is more preferred, and 5% or less is even more preferred. Further, 0.01 to 10% is preferred, 0.05 to 8% is more preferred, and 0.08 to 5% is even more preferred. Within this range, it is more preferred because there is no color change during application and the color uniformity of the coating film is excellent.

[0050] Component (B) in the present invention may be added to either the external aqueous phase or the internal oil phase of the water-in-oil emulsion cosmetic. In particular, when contained in the external aqueous phase, it is considered that when the cosmetic film is formed upon application, the powder containing component (B) is captured by the network formed by component (A), improving the dispersibility. Therefore, in the present invention, it is more preferable that component (B) is contained in the external aqueous phase because the dispersibility of component (B) is improved, and the color change during application and the color uniformity of the coating film are excellent.

[0051] The content of component (B) in the present invention is not particularly limited. Preferably, it is 0.02% or more, more preferably 0.1% or more, and even more preferably 2% or more, based on the total amount of the water-in-oil emulsion cosmetic.

Further, preferably, it is 0.02 - 15%, more preferably 0.1 - 13%, and even more preferably 2 - 10%. Within this range, it is more preferable because the color change during application, the color uniformity of the coating film, and the moisturizing feeling are excellent.

[0052] The mass ratio (A) / (B) of component (A) to component (B) is not particularly limited. For example, preferably, it is 0.02 or more, more preferably 0.3 or more, and even more preferably 0.8 or more.

Within this range, it is more preferable because the color change during application, the color uniformity of the coating film, the feeling without powdery texture, and the moisturizing feeling are excellent.

[0053] [Component (C)] Component (C) in the present invention is a surfactant. The surfactant has the effect of emulsifying the oil phase and the water phase. The surfactant is not particularly limited as long as it is usually used in cosmetics, and any of non-ionic, ionic surfactants can be used regardless of their type.

In the present invention, it is preferable to use two or more kinds of nonionic surfactants in combination, and it is more preferable to use a combination of nonionic surfactants having different HLB (Hydphile-Lipophile Balance). In particular, it is even more preferable to use a combination of a nonionic surfactant having an HLB of 2 to 8 as component (C1) and a nonionic surfactant having an HLB exceeding 8 as component (C2). Here, HLB is an index indicating the balance between hydrophilicity and lipophilicity, and is calculated by the following (Formula 1) by Oda, Teramura, etc. HLB = “inorganic value (IV) / organic value (OV)” × 10 ··· (Formula 1) (Refer to “Organic Conceptual Diagram - Basics and Applications -” written by Yoshio Koda, pages 11 to 17, published by Sankyo Publishing Co., Ltd., issued in 1984)

[0059] In the present invention, when two or more kinds of nonionic surfactants are used in combination, the weighted average HLB is used. As the calculation method of the weighted average HLB, a value obtained by weighted averaging the individual HLB values of the contained component (C) based on the content mass ratio (the following (Formula 2)) is used. Weighted average HLB of component (C) = [(C1: content (%) × HLB) + (C2: content (%) × HLB) + (C3: content (%) × HLB) + ··· / (C1 + C2 + C3 + ···: content (%))] ··· (Formula 2)

[0060] As the weighted average HLB of component (C), 7 or more is preferable. Also, 16 or less is preferable, 15 or less is more preferable, and 14 or less is even more preferable. Also, 7 to 16 is preferable, 7 to 15 is more preferable, and 7 to 14 is even more preferable. If it is within this range, it is more preferable because there is no color change during coating, the color of the coating film is uniform, and the feel is excellent without a powdery feeling.

Examples of water include purified water, hot spring water, ion-exchanged water, deep water, tap water, or steam-distilled water of plants, etc. One or more of them can be appropriately selected and used as needed. Also, plant extract water such as aloe vera, witch hazel, hamamelis, cucumber, lemon, lavender, and rose water may be used.

[0079] The method for producing the oil-in-water emulsified cosmetic of the present invention is not particularly limited and can be produced by a generally known method. Specifically, a dispersion emulsification method, a phase inversion emulsification method, a phase inversion temperature emulsification method, etc. can be mentioned. As the production equipment, any dispersion and emulsification equipment such as a general dispersion can be used. For example, to an oil phase in which component (A), component (C), and an oil agent if necessary are heated and dissolved at 70 to 80°C, an aqueous phase in which component (B), water, and other components if necessary are heated to 70 to 80°C is added, and after emulsifying and mixing by dispersion, it is cooled to room temperature to obtain an oil-in-water emulsified cosmetic.

[0080] The present invention can provide a dispersant for component (B) by component (A) in the oil-in-water emulsified cosmetic containing the above-mentioned component (B) and (C). This is presumably because the powder containing component (B) is captured by the network formed by component (A), preventing component (B) from aggregating.

[0081] As the properties of the oil-in-water emulsified cosmetic of the present invention, it can be implemented in various forms such as liquid, gel, emulsion, cream, semi-solid, solid, etc. Among them, it is preferable to use an emulsion to cream form in order to obtain the effects of the present invention. Here, the emulsion to cream form has a viscosity of 5,000 to 300,000 mPa·s measured using a Brookfield type rotational viscometer at 25°C, preferably 8,000 to 250,000 mPa·s, and more preferably 10,000 to 200,000 mPa·s.

[0082] The water-in-oil type emulsified cosmetic of the present invention can be used as cosmetics for various purposes. For example, skin care cosmetics such as lotion, emulsion, cream, essence, massage cream, pack, hand cream, body lotion, body cream, eye cream, etc., makeup cosmetics such as eyeshadow, mascara, eyebrow, foundation, base, concealer, powder, blusher, lipstick, etc., and cosmetics such as sunscreen. In particular, from the viewpoints of no color change during application, color uniformity of the coating film, a feeling without powdery texture, and moisturizing feeling, makeup cosmetics are preferred, makeup cosmetics presenting skin color are more preferred, and foundation, base, and concealer are even more preferred.

[0083] In addition, the present invention can also have the following constitution.

[0097] (Manufacturing method) A. Components (1) to (6) and components (22) to (23) are uniformly mixed. B. Components (7) to (21) are uniformly mixed. C. B is added to components (24) to (26) and uniformly mixed. D. A is added to C, emulsified, and an oil-in-water type emulsified base is obtained.

[0098] (Evaluation method) Regarding the following items (a) to (d), a usage test was conducted on each sample by 20 professional cosmetic evaluation panelists. The evaluation was carried out in six grades according to the following absolute evaluation, scores were given, and the average value was calculated from the total scores of all panelists for each sample, and the determination was made according to the following four-grade determination criteria.

[0099] (Evaluation Criteria) (a) Whether there is no color difference when comparing the appearance color of each sample with the color of the cosmetic film after application. (b) Whether there is no color unevenness in the cosmetic film applied to the skin for each sample. (c) Whether there is no powdery feeling on the surface of the cosmetic film after applying each sample to the skin and leaving it for 1 minute. (d) Whether a moisturizing effect can be felt when applying each sample to the skin.

[0100] (Absolute Evaluation Criteria) (Evaluation Results): (Score) Very Good: 6 points Good: 5 points Somewhat Good: 4 points Average: 3 points Somewhat Poor: 2 points Poor: 1 point <Four - level Judgment Criteria> (Judgment): (Evaluation Criteria) ◎: Exceeding 5.0 points: (Very Good) 〇: Exceeding 4.0 points and below 5.0 points: (Good) △: Exceeding 2.0 points and below 4.0 points: (Somewhat Poor) ×: 2.0 points and below: (Poor)

[0101] As is clear from the results in Tables 1 and 2, the oil-in-water emulsion base of the examples was excellent in all items: (a) no color change during application, (b) color uniformity of the coating film, (c) a non-powdery feel, and (d) a moisturizing feeling. On the other hand, Comparative Example 1 containing a 50% solution of trimethylsiloxysilicic acid / decamethylcyclopentasiloxane instead of component (A) was insufficient in forming a network for capturing component (B), resulting in a decrease in the dispersibility of component (B). Therefore, it was particularly inferior in terms of no color change during application, color uniformity of the coating film, and a non-powdery feel. Comparative Example 2 not containing component (A) was insufficient in forming a cosmetic film and was significantly inferior particularly in terms of no color change during application and color uniformity of the coating film. Comparative Example 3 containing fine particle titanium dioxide instead of component (B) was significantly inferior particularly in terms of no color change during application and color uniformity of the coating film. Comparative Example 4 not containing component (C) was significantly inferior in terms of no color change during application, color uniformity of the coating film, and a non-powdery feel due to poor emulsification.
