Description

Technical Field

[0001] The present invention relates to a slurry dispersion, a cosmetic, and a method for producing the same, which contain trimethylsiloxysilicic acid.

Background Art

[0002] Generally, in cosmetics, trimethylsiloxysilicic acid is used as a film-forming agent and is blended for the purpose of improving the makeup retention of cosmetics. Patent Document 1 discloses trimethylsiloxysilicic acid having a modified group such as a polyether group, a polyglycerin group, or silicone. However, although research has been conducted on the makeup retention effect such as oil resistance, no research has been conducted on the dispersibility of coloring pigments.

[0003] On the other hand, Patent Document 2 discloses a technique for improving the finish after application by blending trimethylsiloxysilicic acid in makeup cosmetics (Patent Document 2). However, the trimethylsiloxysilicic acid used here is for the purpose of improving the finish after application, and no research has been conducted on improving the color separation or dispersibility of coloring pigments. In makeup cosmetics such as foundation, usability, spreadability, and adhesion when applied to the skin are required, while high aesthetic properties such as no color separation or color unevenness are also desired.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention has been made in view of the above circumstances, and by being incorporated into cosmetics, it has a good feel (light touch), good spreadability (elongation), excellent adhesion, and improved pigment dispersibility, thereby suppressing color unevenness. An object of the present invention is to provide a slurry-like dispersion, a cosmetic containing the same, and a method for producing the same.

Means for Solving the Problems

[0006] In cosmetics that are formulated with pigments for coloring, the pigments aggregate, and color separation phenomena such as sedimentation and separation occur, deteriorating the temporal stability of the cosmetics, losing aesthetic properties, and reducing the commercial value, which can be a problem in some cases. Also, if the amount of surfactants or the like is increased to prevent pigment aggregation and improve dispersibility, problems may occur in terms of usability, such as a heavy and sticky feel, and it is difficult to simultaneously satisfy usability and dispersibility. Such phenomena are particularly prominent in emulsion-type cosmetics such as cream foundations and liquid foundations, which are base makeup. In addition, in these base makeup products, compared to point makeup, the application area is wider, so furthermore, spreadability such as good elongation and the adhesion of the cosmetics to the skin are also emphasized.

[0007] As a result of intensive studies to achieve the above object, the present inventors have found that the above problems can be solved by using a slurry-like dispersion containing (A) one or more selected from trimethylsiloxysilicic acid and its derivatives, (B) a hydrophobically treated colored pigment, and (C) an oil agent that is liquid at 25°C, and have thus arrived at the present invention.

Embodiments for Carrying Out the Invention

[0010] The present invention will be described in detail below. In the present invention, the names of ingredients may be described in cosmetic labeling names or International Nomenclature of Cosmetic Ingredients (INCI).

[0011] I. Slurry-like Dispersion The slurry dispersion of the present invention is a slurry dispersion containing (A) one or more members selected from trimethylsiloxysilicate and its derivatives, (B) a hydrophobically treated color pigment, and (C) an oil agent that is liquid at 25°C.

[0012] [Component (A)] Component (A) of the present invention is one or more selected from trimethylsiloxysilicate and its derivatives, and may be used alone or in combination of two or more. Component (A) improves the dispersibility of the hydrophobically treated color pigment of component (B) in the cosmetic preparation and inhibits color separation, thereby preventing deterioration of the stability over time of the cosmetic preparation and loss of aesthetics.

[0013] Trimethylsiloxysilicate (INCI) is not limited to any compound used in ordinary cosmetics. It is a compound with a crosslinked structure with a siloxane structure as the main skeleton, and has the average composition formula [(CH 3 ) 3 SiO 1 / 2 ] a [SiO 2 ] b (wherein a is 1 to 3, and b is 0.5 to 8) is preferable. 3 ) 3 SiO 1 / 2 ] a (CH 3 Derivatives of trimethylsiloxysilicate in which a portion of the silsesquioxane is substituted with polyoxyalkyl ether, glycerin, or dimethylpolysiloxane can be used. When a derivative of trimethylsiloxysilicate is used, the dispersibility may be good, but the feeling of use may be heavy. When a good feeling of use (lightness) is desired, trimethylsiloxysilicate is preferred.

[0014] The weight average molecular weight of component (A) is preferably from 1,000 to 20,000, more preferably from 1,000 to 10,000, and still more preferably from 1,000 to 3,000, for the purpose of improving the dispersibility of the pigment. In the present invention, the weight average molecular weight is a value determined by GPC (gel permeation chromatography) analysis using polystyrene as a standard substance under the following conditions. [Measurement conditions] Developing solvent: Tetrahydrofuran (THF) Flow rate: 0.6 mL / min Detector: Differential refractive index detector (RI) Column: TSK Guardcolumn SuperH-H TSKgel SuperHM-N (6.0 mm I.D. × 15 cm × 1) TSKgel SuperH2500 (6.0 mm I.D. × 15 cm × 1) (All are manufactured by Tosoh Corporation) Column temperature: 40°C Sample injection volume: 50 μL (THF solution with a concentration of 0.3 mass%)

[0015] The property of component (A) may be liquid, gum-like, paste-like, solid, etc. at 25°C, but liquid is preferred from the viewpoint of the effect of improving color unevenness. Further, component (A) may be used in the form of a solution or dispersion diluted with a solvent from the viewpoint of handling during compounding. As the solvent for dilution, one or more selected from dimethylpolysiloxane, decamethylcyclopentasiloxane, and isododecane are preferred. As commercially available products, KF-7312J (a mixture solution of 50% by mass of decamethylcyclopentasiloxane + 50% by mass of trimethylsiloxysilicic acid), KF-7312K (a mixture solution of 40% by mass of dimethicone (6cs) + 60% by mass of trimethylsiloxysilicic acid), KF-9021 (a mixture solution of 50% by mass of decamethylcyclopentasiloxane + 50% by mass of trimethylsiloxysilicic acid), X-21-5249 (a mixture solution of 50% of decamethylcyclopentasiloxane + 50% of trimethylsiloxysilicic acid), X-21-5595 (a mixture of 40% by mass of isododecane + 60% by mass of trimethylsiloxysilicic acid), etc. (all manufactured by Shin-Etsu Chemical Co., Ltd.) can be used. Specific examples of the liquid include X-21-5250 (a mixture solution of 50% of decamethylcyclopentasiloxane + 50% of trimethylsiloxysilicic acid), X-21-5250L (a mixture solution of 50% by mass of dimethicone (6cs) + 50% by mass of trimethylsiloxysilicic acid), X-21-5616 (a mixture solution of 50% by mass of isododecane + 50% by mass of trimethylsiloxysilicic acid), etc.

[0016] In the present invention, component (A) avoids the aggregation of the hydrophobized coloring pigment and suppresses color separation, but in addition to component (A), when a dispersant or emulsifier generally used in cosmetics, that is, a silicone-modified acrylic polymer, an alkyl polyether-modified silicone, etc. is used alone, the effect may not be exhibited. Since component (A) of the present invention has little influence on emulsification, it is preferably used in both oil-in-water type cosmetics and water-in-oil type cosmetics, but oil-in-water type cosmetics are preferred in terms of adhesion.

[0017] The content of component (A) is preferably 0.1 to 10% by mass, more preferably 0.5 to 5% by mass, and even more preferably 0.8 to 2.5% by mass in the slurry-like dispersion. If it is less than 0.1% by mass, sufficient dispersibility may not be obtained, and if it exceeds 10% by mass, the viscosity of the slurry-like dispersion may increase.

[0018] [Component (B)] Component (B) of the present invention is a hydrophobized coloring pigment and can be used alone or in combination of two or more. The coloring pigment of the hydrophobized coloring pigment according to the present invention is not particularly limited as long as it is a pigment usually used for coloring cosmetics, and includes iron oxide red, iron oxide yellow, titanium oxide white, iron oxide black, red lead, red ocher, yellow ocher, manganese violet, cobalt violet, chromium hydroxide, chromium oxide, cobalt oxide, cobalt titanate, iron oxide-doped titanium oxide, iron titanate, (titanium / titanium oxide) fired product, (Li / cobalt) titanate, cobalt titanate, titanium nitride, iron hydroxide, inorganic brown pigments such as γ-iron oxide, inorganic yellow pigments such as loess, lake pigments obtained by lake-forming tar-based dyes, lake pigments obtained by lake-forming natural pigments, and other colored pigments. Any of them can be used.

[0019] In addition, the shape of the pigment according to the present invention may be any shape such as spherical, substantially spherical, rod-shaped, spindle-shaped, petal-shaped, strip-shaped, irregular-shaped, etc., and there is no particular limitation on its geometric aspect as long as it can impart color to cosmetics. Also, from the viewpoint of hiding power, a pigment having a particle diameter, that is, an average particle diameter in the range of 150 to 600 nm is preferable. The average particle diameter in the present invention refers to a value obtained by analyzing an image taken by TEM (transmission electron microscope) based on the number. If it is less than 150 nm, the hiding power is low, so the coloring efficiency of the cosmetics may be reduced, and if it is larger than 600 nm, the usability may deteriorate.

[0020] Furthermore, the pigment according to the present invention may be partially or entirely surface-treated with an inorganic compound such as alumina, aluminum hydroxide, silica, or hydrous silica.

[0021] The hydrophobic treatment refers to subjecting the coloring pigment to a surface treatment with a hydrophobic treatment agent. The surface hydrophobic treatment agent for the coloring pigment according to the present invention is not particularly limited as long as it can impart hydrophobicity, and examples thereof include silicone treatment agents, waxes, paraffins, organic fluorine compounds such as perfluoroalkyl and phosphates, surfactants, amino acids such as N-acylglutamic acid, and metal soaps such as aluminum stearate and magnesium myristate. A silicone treatment agent is preferred.

[0022] Examples of the silicone treatment agent include silanes or silylating agents such as caprylyl silane (manufactured by Shin-Etsu Chemical Co., Ltd.: AES-3083) and trimethoxysilyl dimethicone, silicones such as dimethyl silicone (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-96A series), methyl hydrogen type polysiloxane (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-99P, KF-9901, etc.), silicone branched type silicone treatment agents (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-9908, KF-9909, etc.), and silicone compounds such as acrylic silicone (manufactured by Shin-Etsu Chemical Co., Ltd.: KP-574, KP-541). Among them, the silicone powder treatment agent described in Japanese Patent No. 3912961 is preferably used, and triethoxysilyl ethyl polydimethylsiloxyethyl hexyl dimethicone, which is a dimethyl polysiloxane having a triethoxysilyl group, a polydimethylsiloxyethyl group, and a hexyl group in the side chain (manufactured by Shin-Etsu Chemical Co., Ltd.: KF-9909), etc., can be effectively used from the viewpoint of exhibiting high affinity even when the dispersion medium for dispersing the highly hydrophobic treated coloring pigment according to the present invention has a mixed composition such as silicone and hydrocarbon. Further, the above surface hydrophobic treatment agent can be used alone or in combination of two or more.

[0023] In the present invention, the method of surface-treating a coloring pigment with a hydrophobizing agent is not particularly limited and can be carried out by known methods. The surface treatment method can be broadly classified into a dry method and a wet method. As the dry method, for example, any stirrer, grinder, mixer, disperser, etc., such as a Henschel mixer, ball mill, jet mill, kneader, planetary mixer, sand mill, attritor, ribbon blender, disperser mixer, homomixer, etc., can be used to mix / contact the coloring pigment used in the present invention with the hydrophobizing agent for treatment. At this time, treatment may be carried out while applying energy such as heating, mechanochemical mechanical force, and superheated steam. Further, after sufficiently mixing or contacting the coloring pigment and the hydrophobizing agent, energy such as heating, mechanochemical mechanical force, and superheated steam may be separately applied for treatment. Or when mixing or contacting the hydrophobizing agent with the coloring pigment, for the purpose of improving the dispersion efficiency of the hydrophobizing agent, the hydrophobizing agent may be previously dissolved or dispersed in an arbitrary amount of water, solvent or supercritical fluid, and means such as spraying this on the coloring pigment may be used. As the wet method, it is possible to disperse, mix or contact the coloring pigment and the hydrophobizing agent in water, solvent or supercritical fluid, then evaporate the solvent, and further apply energy such as heating, mechanochemical mechanical force or superheated steam for treatment.

[0024] Specific examples of the colored pigment subjected to the hydrophobized surface treatment include the KTP-09 series, particularly KTP-09W, 09R, 09Y, 09B, etc. (manufactured by Shin-Etsu Chemical Co., Ltd.).

[0025] The content of the component (B) is preferably 20 to 89.9% by mass, more preferably 30 to 85% by mass, and even more preferably 70 to 85% by mass in the slurry-like dispersion. If it is less than 20% by mass, the coloring power may be insufficient, and if it exceeds 90% by mass, the aggregation of the coloring pigments may become strong.

[0026] In the slurry-like dispersion, the mass ratio (A) / (B) of component (A) to component (B) is preferably from 0.005 to 0.05, more preferably from 0.01 to 0.03. By setting the above range to 0.005 to 0.05, the dispersion effect of component (A) on component (B) can be obtained more effectively.

[0027] [Component (C)] Component (C) is an oil agent that is liquid at 25°C and can be used alone or in combination of two or more. The oil agent that is liquid at 25°C is not particularly limited as long as it is used in ordinary cosmetics. For example, vegetable oils such as jojoba oil and olive oil, animal oils such as liquid lanolin, linear or branched hydrocarbons such as liquid paraffin, light isoparaffin, fluid isoparaffin, squalane, and squalene, esters such as alcohol fatty acid esters and polyhydric alcohol fatty acid esters, and silicones such as dimethylpolysiloxane, dimethylcyclopolysiloxane, and methylphenylpolysiloxane can be used.

[0028] Among these, low-viscosity hydrocarbons, silicones, esters, etc. are preferred. More specifically, as the hydrocarbon, isododecane, dodecane, liquid paraffin, squalane, (C13-15) alkane are preferred, and as the ester, isotridecyl isononanoate, isononyl isononanoate, ethylhexyl palmitate, triethylhexanoin, cetyl ethylhexanoate, hexyl laurate, glyceryl tri(caprylate / caprate) are preferred. As the silicone, dimethylpolysiloxane, decamethylcyclopentasiloxane, diphenylsiloxyphenyltrimethicone, methyltrimethicone, etc. with a viscosity of 50 mm 2 / s or less at 25°C are preferred.

[0029] The content of component (C) is preferably 10 to 40% by mass, more preferably 15 to 35% by mass, and even more preferably 15 to 25% by mass in the slurry-like dispersion. If it is less than 10% by mass, there is a risk that wetting to component (B) may be insufficient, and if it exceeds 40% by mass, there is a risk that the fibrillation force may be insufficient. In particular, when dispersing with a three-roll mill, 15 to 30% by mass is preferable, and 15 to 25% by mass is even more preferable.

[0030] In addition, the oily agent that is liquid at 25 °C and used as component (C), for the purpose of adjusting the feel of use and imparting emolliency, etc. to the cosmetic as long as it satisfies the content of the slurry-like dispersion shown in the present invention for preparing the slurry-like dispersion, can be separately blended into the cosmetic as other optional components described later as a liquid oily component.

[0031] Component (C) of the present invention greatly affects the stability and feel of use of the cosmetic. When the ratio of silicone in component (C) is large, it is preferable in terms of compatibility with component (A), wettability to component (B), swelling property of component (D) described later, and compatibility with other components, but it is difficult to obtain an adhesion feeling. By reducing the ratio of silicone in component (C), an adhesion feeling can be obtained, but the above-mentioned compatibility, wettability, and swelling property decrease, and color unevenness is likely to occur. In addition, good dispersibility can be obtained by the production method of the present invention described later. When an adhesion feeling is desired, the ratio of non-silicone in component (C) is preferably 30% by mass or more, more preferably 50% by mass or more, even more preferably 80% by mass or more, and most preferably 100% by mass. The blending amount of silicone is preferably 15% by mass or less, more preferably 6% by mass or less, even more preferably 1% by mass or less, and most preferably not blended, and it is possible to achieve both an adhesion feeling and suppression of color unevenness.

[0032] [Optional Components] The slurry-like dispersion of the present invention may contain a film-forming agent, powder, ultraviolet scattering agent, ultraviolet absorber, oily agent that is not liquid, and component (D) described later. From the viewpoints of pigment dispersibility and suppression of the decrease in the concentration of component (A), Minute ( A) 、It is preferably composed of only component (B) and component (C).

[0033] [Method for producing a slurry-like dispersion] The method for producing the slurry-like dispersion of the present invention comprises a step (I) of mixing at least one selected from (A) trimethylsiloxysilicic acid and its derivatives, (B) a hydrophobized coloring pigment, and (C) an oily agent that is liquid at 25°C to prepare a slurry-like dispersion.

[0034] When preparing the slurry-like dispersion according to the present invention, there are no particular limitations on the method and apparatus, and it can be carried out by known methods. For example, any stirrer, grinder, mixer, disperser, etc., such as a Henschel mixer, ball mill, kneader, planetary mixer, ribbon blender, disperser mixer, homomixer, roll mill, etc., can be used. In particular, from the viewpoint of mixing efficiency, it is preferable to use a three-roll mill for mixing and stirring. The stirring and mixing temperature is not particularly limited, and 20°C to 105°C is preferable, and room temperature is particularly more preferable.

[0035] II. Cosmetics The cosmetics of the present invention contain 1 to 30% by mass of the above slurry-like dispersion in the cosmetics, more preferably 4 to 25% by mass, and even more preferably 10 to 25% by mass. The cosmetics may be water-in-oil type emulsified cosmetics or oil-in-water type emulsified cosmetics, but water-in-oil type emulsified cosmetics are preferable from the viewpoint of adhesion, and examples include milk-like, cream-like, stick-like, solid-like, etc. Specific cosmetics include makeup bases, concealers, liquid foundations, cream foundations, solid foundations, blushes, eyeshadows, mascaras, eyeliners, eyebrows, lipsticks, etc. made by blending the above cosmetic components, and sunscreen emulsions and sunscreen creams containing hydrophobized coloring pigments, etc. Among these, in particular, foundations, makeup bases, and sunscreens containing multiple types of coloring pigments for the purpose of applying to the skin are preferable.

[0036] [Component (D)] In the case of the cosmetic of the present invention, particularly in the case of an oil-in-water type emulsified cosmetic, it is preferable to blend the component (D) an organically modified clay mineral from the viewpoint of improving the pigment dispersion stability (suppressing color separation). The organically modified clay mineral can be used alone or in combination of two or more. The organically modified clay mineral is not particularly limited as long as it is used in ordinary cosmetics. For example, cationically modified clay minerals substituted with quaternary ammonium ions can be mentioned. Specifically, layered clay minerals such as bentonite, laponite, hectorite, montmorillonite, and magnesium aluminum silicate are treated with a quaternary ammonium salt type cationic surfactant so that the sodium ions between the layers of the layered clay mineral are replaced with quaternary ammonium ions, and cationically modified clay minerals can be used.

[0037] More specifically, dimethyldistearylammonium hectorite, dimethyldistearylammonium bentonite, benzyldimethylstearylammonium hectorite, etc. are preferable, and dimethyldistearylammonium hectorite is more preferable. Also, as commercially available products, Benton 38, Benton 38VCG, Benton 27 (manufactured by Elementis), etc. can be mentioned.

[0038] The content of the component (D) is preferably 1.5% by mass or less as the amount in the whole cosmetic. That is, the component (D) does not necessarily have to be blended within the range where the effects of the present invention are exhibited. However, when it is desired to have excellent adhesion to the skin and form a uniform thin film on the skin, 1.5% by mass or less (0 to 1.5% by mass) in the whole cosmetic is preferable, and 0.1 to 0.8% by mass is more preferable. From the viewpoint of suppressing the influence on the usability due to the component (D), 0.4% by mass or less is preferable. Even when the component (D) is not blended, good dispersibility can be obtained in the case of the slurry-like dispersion of the present invention. When blended in an amount exceeding 1.5% by mass, the film quality formed on the skin may become non-uniform, or the stability of the cosmetic over time in terms of quality may deteriorate.

[0095] (Manufacturing method) Components 1 to 6 were mixed uniformly (preparation of the oil phase component). Separately, components 7 to 13 were roller-treated (preparation of the slurry-like dispersion). This slurry-like dispersion was added to the previous oil phase component and uniformly mixed. Further, components 14 to 17 prepared separately (preparation of the aqueous phase component) were gently added thereto and stirred to form an emulsion. It was added to and mixed with the aforementioned emulsion. This was filled into a predetermined container to obtain a foundation.

[0096] Regarding the obtained water-in-oil (W / O) type foundation, a usage test was conducted by 10 female professional panelists on (1) usability (good feel; light feel), (2) spreadability (good elongation), (3) adhesion, and (4) pigment dispersibility, and evaluated according to the following evaluation criteria. The evaluation results of Examples 1 to 9 and Comparative Examples 1 to 10 are also shown in the table.

[0097] (Evaluation Criteria) 5 points: Very good (1), (2), (3), no color separation (4) 4 points: Good (1), (2), (3), almost no color separation (4) 3 points: Ordinary (1), (2), (3), slightly color separation (4) 2 points: Slightly poor (1), (2), (3), color separation (4) 1 point: Poor (1), (2), (3), very color separation (4) And for the obtained average score, it was judged with ○× according to the following criteria. (Judgment of Average Score) The obtained average score is 4.5 points or more ◎ The obtained average score is 3.5 points or more and less than 4.5 points ○ The obtained average score is 2.5 points or more and less than 3.5 points △ The obtained average score is 1.5 points or more and less than 2.5 points × The obtained average score is less than 1.5 points ×× ◎, ○, △ or above are considered qualified.

[0098] As is clear from the above results, the foundations of Examples 1 to 9 were demonstrated to suppress color separation while maintaining good usability and spreadability compared to Comparative Examples 1 to 10. When trying to obtain adhesion, color separation is likely to occur due to polar oil, but it was confirmed that the present invention suppresses the occurrence of color separation. Furthermore, it was effective when component (B) was a dispersion in which components (A) and (C) were dispersed in advance. In addition, although the blending of component (D) is effective in suppressing the occurrence of color separation, it was found that the blending amount of component (D) can be reduced by the present invention to improve the usability.
