Description

[Technical Field]

[0001] The present invention relates to a transparent multi-layer dispersion composition. [Background technology]

[0002] Along with recent hairstyle trends, oil products have become increasingly popular in the hair care market, revitalizing the market. Oils are also gaining attention in the beauty market, including skin care, with new products being released one after another.

[0003] Oils have a variety of beneficial effects, including providing hair with a treatment effect, reducing damage, adding moisture, hydration, and shine, improving hair's smoothness, and improving manageability. Needless to say, they also have similar effects on the skin of the body and face. For example, there are oils on the market that use silicone oils or low-viscosity hydrocarbons, as well as completely different oils made from natural oils such as camellia oil. Each type is chosen based on the user's taste and preference, damage care effects, etc. However, despite the differences in ingredients, they all share the same oily properties, and the resulting complaints about oily feel and stickiness are also common to all.

[0004] Therefore, there has been a demand for a new formulation that has a treatment effect that utilizes the oily properties of oil formulations while also having water-based properties, that can eliminate complaints such as the oily feel and stickiness that are characteristic of oils, and that has a unique and beautiful appearance that will be chosen by consumers.

[0005] Compositions that address these dissatisfaction include compositions in which fine oil particles are dispersed (e.g., Patent Document 1) and formulations in which spherical oily components are dispersed by adding powder (e.g., Patent Document 2), but these do not satisfy the above-mentioned performance and appearance requirements.

[0007] The present invention has been made in view of the above circumstances, and aims to provide a transparent multilayer dispersion composition that has the effects of an oil preparation, such as a treatment effect, a damage care effect, and a moisturizing and gloss-imparting effect, while at the same time possessing aqueous properties, thereby eliminating problems such as oily feel and stickiness that are characteristic of oils, and further has a unique and beautiful appearance.

[Brief explanation of the drawings]

[0024] [Figure 1] 1 is a diagram illustrating one embodiment of a transparent multilayer dispersion composition of the present invention. [Figure 2] FIG. 1 is a diagram showing a conventional mixture of oily granular material and aqueous liquid material. DETAILED DESCRIPTION OF THE INVENTION

[0025] The transparent multi-layer dispersion composition of the present invention will be described in detail below.

[0026] <Transparent multilayer dispersion composition> The transparent multilayer dispersion composition of the present invention is characterized by comprising two or more layers with different properties. Here, "different properties" refers to the properties of layers that do not easily mix with each other by themselves, such as the relationship between water and oil, water and powder, or oil and powder. Furthermore, a multilayer dispersion refers to a state in which two or more dispersions with different properties exist independently in each layer. Here, the state in which two or more dispersions with different properties exist independently in each layer of the present invention does not include a typical emulsion, but an emulsion-like composition may coexist in another layer. For example, a water-in-oil emulsion-like dispersoid may exist independently suspended in an aqueous dispersion medium.

[0027] As shown in Figure 1, the transparent multi-layer dispersion composition of the present invention is a multi-layer dispersion comprising two or more layers with different properties, wherein at least one of the two or more layers is an outer aqueous layer composed of a water-soluble composition and at least one is an inner oily layer composed of an oil-soluble composition, and the oily inner layer composed of the oil-soluble composition is present in whole or in part in a particulate form. Examples of the composition of the present invention include a composition in which one oil-soluble composition is present independently in a particulate form within one or more layers composed of one or more water-soluble compositions, or a composition in which two or more oil-soluble compositions are present independently in a particulate form within one or more layers composed of one or more water-soluble compositions. By combining an outer aqueous layer and an inner oily layer having the characteristics described in detail below, the transparent multi-layer dispersion composition of the present invention allows the oily granules to stably and independently float without separation from the aqueous layer, even without the addition of a surfactant, as occurs when conventional oily granules are mixed into an aqueous liquid, as shown in Figure 2.

[0028] The transparent multi-layer dispersion composition of the present invention has a transparent appearance. A transparent appearance means, for example, that the lightness L value of the transparent multi-layer dispersion composition measured using a color meter is 50 or more. Preferably, the L value of the transparent multi-layer dispersion composition is 70 or more, and more preferably, the L value of the transparent multi-layer dispersion composition is 90 or more. The lightness can be measured using any color meter. For example, the ColorMeter ZE6000 manufactured by Nippon Denshoku Industries Co., Ltd. is one such example.

[0029] The transparent multilayer dispersion composition of the present invention is a multilayer dispersion composition comprising a plurality of independently existing layers, characterized in that the plurality of layers comprises an aqueous outer layer having a viscosity of 100 to 6000 mPa·s and an oily inner layer having a viscosity of 10 to 5000 mPa·s. Preferably, the transparent multilayer dispersion composition of the present invention comprises an aqueous outer layer having a viscosity of 1500 to 3500 mPa·s and an oily inner layer having a viscosity of 100 to 1500 mPa·s. Having the oily inner layer and the aqueous outer layer with viscosities within the above ranges ensures a beautiful appearance. From the perspective of a particularly beautiful appearance, it is preferable that the viscosity of the aqueous outer layer is 1500 to 3500 mPa·s and that of the oily inner layer is 100 to 1500 mPa·s. In the present invention, a beautiful appearance refers to a unique appearance in which the outer and inner layers are transparent and the particles comprising the inner layer are large and independently suspended within the outer layer.

[0030] In this specification, the term "viscosity" refers to the viscosity at 25°C, and is a value measured using a viscometer (DV-1 viscometer manufactured by Brookfield).

[0031] The transparent multilayer dispersion composition of the present invention preferably comprises an oily inner layer composed of particles with an average particle radius of 0.1 mm or more suspended in an aqueous outer layer. In the present invention, the particle radius of the oily layer is the geometric particle radius measured on a two-dimensional screen using a microscope. In this specification, the average particle radius refers to the radius at which the highest frequency is visually recognized on a particle size histogram graph, the so-called modal radius. Here, a histogram is a type of statistical graph with frequency on the vertical axis and class on the horizontal axis, and is a graphical diagram primarily used in statistics, mathematics, image processing, etc. to visually recognize the distribution of data. An average particle diameter of 0.1 mm or more is preferred from the perspective of aesthetic appearance.

[0032] The transparent multi-layer dispersion composition of the present invention preferably has a mass ratio of the outer layer to the inner layer of 99.9:0.01 to 50:50. When the inner layer to outer layer ratio is 50 or less, the dispersion stability of the particles in the transparent multi-layer dispersion composition is good and independent spherical layers can be formed, and when the ratio is 0.01 or more, the effects of the oil formulation, such as treatment effect, damage care effect, moisturizing effect, and gloss-imparting effect, can be satisfactorily exhibited, which is preferable.

[0033] The transparent multilayer dispersion composition of the present invention has an L value, which indicates the brightness of the outer layer, of 50 or more. Preferably, the L value of the outer layer is 70 or more, and more preferably, the L value of the outer layer is 90 or more. The brightness can be measured using any color meter. For example, the ColorMeter ZE6000 manufactured by Nippon Denshoku Industries Co., Ltd. is one example. When the brightness L value is 50 or more, the composition has transparency in appearance, and a transparent multilayer dispersion composition with excellent appearance quality can be provided.

[0034] The transparent multilayer dispersion composition of the present invention is a composition having an outer layer containing a polymer whose lightness L value of a 0.5% by mass aqueous solution is at least 35. Furthermore, the polymer is preferably a (C) water-soluble, poorly ethanol-soluble thickening polymer.

[0035] In the transparent multilayer dispersion composition of the present invention, it is preferred that the specific gravity of the outer aqueous layer and the inner oily layer each be in the range of 0.900 to 1.200, or that the density of the outer aqueous layer and the inner oily layer each be in the range of 0.900 to 1.200.

[0036] Furthermore, in the transparent multi-layer dispersion composition of the present invention, the outer layer contains (A) water and one or more (C) water-soluble, poorly ethanol-soluble thickening polymers. The outer layer of the present invention may also contain (B) ethanol. When the transparent multi-layer dispersion composition of the present invention contains component (B), the ethanol may be ethanol or denatured ethanol not specified by the government, and such ethanol may be obtained by either a fermentation method or a synthetic method.

[0037] When the composition contains the component (B) of the present invention, the ethanol content is 50.0% by mass or less, preferably 35.0% by mass or less. The lower limit of the content of the component (B) is preferably 0.1% by mass or more, more preferably 1% by mass or more, and even more preferably 5% by mass or more. A content of the component (B) of 50.0% by mass or less is desirable because the thickening polymer (C) swells sufficiently, thereby adjusting the viscosity, specific gravity, and density, and maintaining the qualities of the composition, such as texture, stability, and transparency. Here, the ethanol content is based on the total mass of the transparent multilayer dispersion composition of the present invention.

[0038] The thickening polymer, component (C) of the present invention, is a polymer that exhibits thickening properties in an aqueous solution. It may be a natural polymer derived from a plant, animal, or microorganism, a natural polymer derivative, a synthetic polymer, or an inorganic thickener. Examples of the thickening polymer include, but are not limited to, plant-based polymers such as alginic acid, carrageenan, agar, furcella, guar gum, quince seed, konjac mannan, tamarind gum, tara gum, starch, dextrin, locust bean gum, gum arabic, ghatti gum, karaya gum, tragacanth gum, arabinogalactan, pectin, quince, wheat protein, and soy protein; animal-based polymers such as albumin, casein, gelatin, chitosan, and hyaluronic acid; and curdlan, xanthan gum, gellan gum, cyclodextrin, dextrin, protease, and the like. Microbial-based materials such as lulan and hyaluronic acid; cellulose-based materials such as microcrystalline cellulose, methylcellulose, ethylcellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethylcellulose, carboxymethylcellulose, cationic cellulose, and stearoxyhydroxypropylmethylcellulose; starch-based materials such as starch phosphate esters and sodium starch glycolate; guar gum-based materials such as cationic guar gum, carboxymethyl-hydroxypropylated guar gum, and hydroxypropylated guar gum;Synthetic polymers with a basic backbone such as acrylic, methacrylic, vinyl, ether, maleic anhydride, polypiperidine, polyalkylenepolyamine, polyethyleneimine, polyamide, and polycation, for example, carboxyvinyl polymer, polyacrylic acid amide, sodium polyacrylate, polyethyleneimine, highly polymerized polyethylene glycol, starch-sodium acrylate graft polymer, polyvinyl alcohol, polyvinylpyrrolidone, polyacrylate, polyacrylate-1, polyacrylate crosspolymer-11, vinyl acetate-vinylpyrrolidone copolymer, (ammonium acryloyldimethyltaurate / carboxyethylammonium acrylate) crosspolymer, (ammonium acryloyldimethyltaurate / beheneth-25 methacrylate) crosspolymer, alkyl acrylate-alkyl methacrylate-methacrylic acid Examples of the thickener include polyoxyethylene stearyl ether copolymer emulsion, (sodium acrylate / sodium acryloyldimethyltaurate) copolymer, (hydroxyethyl acrylate / sodium acryloyldimethyltaurate) copolymer, (acrylamide / ammonium acrylate) copolymer, (acrylates / C10-30 alkyl acrylate) crosspolymer, (acrylates / steareth-20 itaconate) copolymer, (VP / hexadecene) copolymer, (ammonium acryloyldimethyltaurate / VP) copolymer, (VP / methacrylamide / vinylimidazole) copolymer, (acrylic acid / vinylpyrrolidone) copolymer, and (methyl vinyl ether / maleic acid) crosspolymer. Other examples include inorganic thickeners such as hectorite, dimethyl distearyl ammonium hectorite, bentonite, and saponite. From the viewpoints of beautiful appearance, stability, and good feel, it is preferable to use a polymer that is particularly soluble in water and slightly soluble in ethanol, and more preferably a polymer that is soluble in water, slightly soluble in ethanol, and is nonionic. Note that "soluble in water" means that when a 0.5% by mass aqueous solution (25°C) is prepared, the polymer is completely dissolved, leaving no solid matter. Furthermore, "slightly soluble in ethanol" means that when a 0.5% by mass ethanol solution (25°C) is prepared, solid matter remains.

[0039] The thickening polymer (C) of the present invention may be a single polymer or a combination of two or more polymers. The content of the thickening polymer (C) is 0.01 to 30% by mass, preferably 0.05 to 10.0% by mass, based on the total mass of the transparent multi-layer dispersion composition of the present invention. A content of 0.05% by mass or more is effective in maintaining the oily inner layer in a particulate state and providing excellent dispersion stability, while a content of 30% by mass or less is preferable because it prevents a significant increase in the viscosity of the outer layer and allows the fluidity of the transparent multi-layer dispersion composition to be maintained.

[0040] The component (C) of the present invention may be neutralized with salts or acids as necessary before use, and may be used alone or in combination of two or more.

[0041] The transparent multilayer dispersion composition of the present invention contains the above-mentioned components (A) to (C) in the aqueous outer layer and (D) an oily agent that is liquid at room temperature in the oily inner layer. In the present invention, component (D) can be a combination of (D1) a silicone oil that is liquid at room temperature, which will be described in detail below, and (D2) an oily agent that is liquid at room temperature other than (D1). In this specification, "room temperature" refers to 25°C.

[0042] The liquid oil of component (D) of the present invention is an oil that is liquid at room temperature. Component (D1) may contain a silicone oil that is liquid at room temperature and has a viscosity of 10 mPa s or greater at 25°C. The silicone oil is not particularly limited, and examples thereof include various silicones such as volatile dimethicone, highly polymerized dimethicone, silicone blends, various modified silicones, and silicone resins, such as dimethicone, cyclomethicone, cyclopentasiloxane, phenyl trimethicone, diphenylsiloxyphenyl trimethicone, polysilicone-13, dimethiconol, trimethylpentaphenyltrisiloxane, amodimethicone, (divinyldimethicone / dimethicone) copolymer, cyclohexasiloxane, caprylyl methicone, cetyl dimethicone, bis(hydroxyethoxypropyl)dimethicone, (diphenylmethylsiloxyphenylmethicone / phenylsilsesquioxane) crosspolymer, (dimethicone / vinyldimethicone) crosspolymer, and dimethicone crosspolymer. Among these, dimethicone is preferred because it provides a particularly good feel.

[0043] The component (D) of the present invention may further contain component (D2), which is another liquid oil (excluding the silicone oil (D1) described above). Although not particularly limited, at least one of oils and fats such as ester oils, hydrocarbon oils, natural oils, higher alcohols, and higher fatty acids may be contained. For example, isodecyl neopentanoate, ethylhexyl isononanoate, isopropyl myristate, hexyl laurate, diisobutyl adipate, isononyl isononanoate, isopropyl palmitate, isodecyl isononanoate, ethyl isostearate, isopropyl isostearate, hexyldecyl ethylhexanoate, diethylhexyl succinate, isotridecyl isononanoate, neopentyl glycol diethylhexanoate, isobutyl isostearate, cetyl ethylhexanoate, ethylhexyl palmitate, isostearyl neopentanoate, neopentyl glycol dicaprate, isocetyl myristate, neopentyl glycol diisononanoate, caprylic / capric triglyceride, octyldodecyl myristate, isocetyl stearate, triethylhexanoin, hexyldecyl isostearate, isostearyl isostearate, tricyclodecanemethyl isononanoate ester oils such as ethylhexyl hydroxystearate, trimethylolpropane triethylhexanoate, ethylhexyl hydroxystearate, octyldodecyl stearoyloxystearate, diisopropyl dilinoleate, triisostearin, trimethylolpropane triisostearate, pentaerythrityl tetraisostearate, polyglyceryl-2 triisostearate, polyglyceryl-2 diisostearate, sodium isostearoyl lactylate, dipentaerythrityl hexaisononanoate, polyglyceryl-2 isostearate, diisostearyl malate, and polyglyceryl-3 diisostearate; liquid hydrocarbons such as light isoparaffin (isododecane), light liquid isoparaffin, α-olefin oligomer, synthetic squalane, vegetable squalane, polybutene, hydrogenated polyisobutylene, and liquid paraffin; unsaturated fatty acids such as oleic acid, isostearic acid, undecylenic acid, linoleic acid, and linolenic acid, and branched fatty acids;Examples of suitable oils include liquid higher alcohols such as oleyl alcohol, jojoba alcohol, isostearyl alcohol, octyldodecanol, hexyldecanol, benzyl alcohol, and lauryl alcohol; and natural oils such as rice germ oil, rice bran oil, apricot oil, castor oil, camellia oil, rosehip oil, grapeseed oil, olive oil, jojoba oil, sesame oil, perilla oil, southern oat oil, walnut oil, avocado oil, coconut oil, sunflower oil, and linseed oil. Among these, liquid ester oils and hydrocarbons are particularly preferred.

[0044] The liquid oil of component (D) of the present invention may be a single component (D1) or a combination of two or more components, or may be a single component (D1) or a combination of components (D1) and (D2). The content of the liquid oil of component (D) is preferably in the range of 0.1 to 50 mass% relative to the total mass of the transparent multilayer dispersion composition of the present invention, and more preferably in the range of 1 to 30 mass%. A content of 50 mass% or less is preferred because the composition has good stability and can form independent spherical layers.

[0045] The viscosity of component (D) of the present invention is preferably 10 mPa·s or more, more preferably 50 mPa·s or more, and even more preferably 100 mPa·s or more.

[0046] The transparent multilayer dispersion composition of the present invention may further contain an aqueous rheology control agent as component (E). The aqueous rheology control agent is not particularly limited, but is an agent that, when added to an aqueous solution, improves the viscosity of the aqueous solution (excluding component (C)). Specific examples thereof include polyhydric alcohols such as ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, polyoxyethylene polyoxypropylene glycol, glycerin, diglycerin, polyglycerin, isoprene glycol, and 1,3-butylene glycol; polyols such as polyoxyethylene glycerin, polyoxypropylene glyceryl ether, polyoxyethylene polyoxypropylene glyceryl ether, polyoxybutylene polyoxyethylene polyoxypropylene glyceryl ether, polyoxyethylene polyoxypropylene trimethylolpropane, polyoxypropylene diglyceryl ether, and polyoxyethylene polyoxypropylene alkyl ether; sugar alcohols such as sorbitol, mannitol, xylitol, maltitol, and erythritol; sugars such as glucose, sucrose, lactose, maltose, trehalose, and glycosyltrehalose; water-soluble esters such as bisethoxydiglycol succinate, bisethoxydiglycol cyclohexane-1,4-dicarboxylate, and polyglyceryl-10 (eicosandioate / tetradecanedioate); water-soluble silicone compounds such as polyether-modified silicone; amino acids, salts, and acids such as serine, valine, alanine, glycine, leucine, glutamic acid, histidine, aspartic acid, threonine, isoleucine, phenylalanine, proline, arginine, tyrosine, phenylalanine, and trimethylglycine.

[0047] The aqueous rheology modifier (component (E)) of the present invention may be used alone or in combination of two or more. The content of component (E) is preferably in the range of 0.01 to 30% by mass, more preferably 0.1 to 10% by mass, based on the total mass of the transparent multilayer dispersion composition of the present invention. A content of 0.01% by mass or more provides good usability, such as smoothness, and good viscosity and specific gravity adjustment, while a content of 30% by mass or less is preferred because it prevents tactile problems, such as stickiness, and maintains quality without disrupting the boundaries between layers with different properties.

[0048] Furthermore, the component (F) of the present invention may contain the following ingredients. Examples include, but are not limited to, fragrances, essential oils, fruit juices and plant extracts, extracts, natural pigments with a general structure such as flavonoids, carotenoids, quinones, and porphyrins, and prophenol-containing extracts such as caramel and butterfly pea extract.

[0049] The component (F) of the present invention may be used alone or in combination of two or more types, and may be contained in the outer layer, the inner layer, or both.

[0050] The composition of the present invention may be used as any of a skin care composition, a body care composition, and a hair care composition, and may be in either a rinse-in or rinse-off form.

[0051] Furthermore, as needed, other additional components typically used in cosmetics and the like can be blended within limits that do not impair the effects of the present invention. These additional components include, for example, antibacterial agents, ultraviolet absorbers, antioxidants, physiologically active substances, whitening agents, vitamins and their derivatives, anti-inflammatory agents, anti-inflammatory agents, hair growth agents, blood circulation promoters, stimulants, hormones, anti-wrinkle agents, anti-aging agents, firming agents, cooling agents, warming agents, wound healing promoters, irritation alleviators, analgesics, cell activators, antipruritics, exfoliants, keratolytic agents, antiperspirants, cooling agents, astringents, and the like, as well as chelating agents, electrolytes, alkalis, acids, surfactants, setting resins, solid powders, and the like.

[0052] The method for producing the transparent multilayer dispersion composition of the present invention is not particularly limited as long as it can provide a transparent multilayer dispersion composition that can impart a beautiful appearance (particle morphology, transparency of the outer layer, and transparency of the multilayer dispersion composition), oily properties (shiny and smooth hair), aqueous properties (straightening and manageability), oily properties on the skin (non-sticky), and aqueous properties on the skin (moisturizing and hydrating), thereby eliminating complaints such as stickiness. For example, the composition can be obtained by mixing an aqueous composition that forms the aqueous outer layer with an oily composition that forms the oily inner layer. The aqueous composition can be prepared by dissolving various water-soluble components in water, which is component (A), and the oily composition can be prepared by dissolving various oil-soluble components in oil, which is component (D).

[0053] Furthermore, in the method for producing a transparent multilayer dispersion composition of the present invention, it is preferable to add component (C) to an aqueous composition or an oil-based composition. When component (C) is added to an oil-based composition, component (C) gradually migrates from the oil-based inner layer to the aqueous outer layer after the aqueous composition and the oil-based composition are mixed. Therefore, the aqueous composition is mixed with the oil-based composition in a low viscosity state, thereby forming a good mixed state. Then, after component (C) migrates to the aqueous outer layer, the viscosity of the aqueous outer layer increases, and a transparent multilayer dispersion composition with excellent dispersion stability can be obtained.

[0054] The aqueous composition and the oily composition can be mixed by a conventional mixing means. For example, a dynamic agitation mixer such as a propeller agitator or a homomixer that applies shear force to a liquid to mix it, or a static agitation mixer such as a static mixer can be used. Alternatively, a shaking mixing means that mixes by shaking a container can be used. The aqueous composition and the oily composition may be mixed immediately before use of the transparent multi-layer dispersion composition.

[0055] In the method for producing a transparent multi-layer dispersion composition of the present invention, the oily inner layer is preferably adjusted to have a particle shape with an average particle radius of 0.1 mm or more. By adjusting the average particle radius of the oily inner layer to 0.1 mm or more, a transparent multi-layer dispersion composition with excellent transparency and beautiful appearance can be obtained. The average particle radius of the oily inner layer can be adjusted to a desired size by adjusting the performance (stirring and mixing force) of the mixing means. [Example]

[0056] The present invention will be described in more detail below with reference to examples, but the technical scope of the present invention is not limited to these examples. Regarding the multilayer dispersion compositions described in the examples and comparative examples, test methods for evaluating their appearance (particle morphology, transparency of the outer layer, and transparency of the multilayer dispersion composition), oily properties (gloss and smoothness to hair), aqueous properties (straightening and smoothing), oily properties on the skin (non-sticky feeling), and aqueous properties on the skin (moisture and hydration) are shown below.

[0057] (1) Beautiful appearance (transparency of the outer layer) Each sample (outer layer) was prepared in a room maintained at 25°C, and the lightness L value was measured and evaluated using a color meter "ColorMeterZE6000" manufactured by Nippon Denshoku Industries Co., Ltd. The evaluation criteria were as follows:

[0058] <Outer layer transparency evaluation criteria> ◎: Lightness L value is 70 or more ○: Lightness L value is over 35 and less than 70 ×: Lightness L value 35 or less
