Abstract
Description
[Technical Field]
[0001] The present invention relates to a multi-layered cosmetic composition. [Background technology]
[0002] There are consumer needs to prevent makeup from coming off due to sweat or rubbing against clothes after makeup application.
[0003] For example, Patent Document 1 discloses a skin cosmetic that is particularly in the form of a lotion or cream and is used over a foundation with makeup to moisturize the skin, and that has excellent long-term stability, does not cause the foundation to smudge even when applied over a face with makeup, and provides an excellent feeling of moisture over time.
[0004] Furthermore, Patent Document 2 proposes a water-based or oil-in-water mist cosmetic that contains a specific water-soluble thickener and is filled in a pump-type spray container with a diameter of 0.25 to 0.55 mm.
[0005] For example, Patent Document 3 proposes, as claim 1, a multi-layered makeup protection cosmetic composition that contains an oil-soluble film-forming agent, 40 to 95% by mass of water, and a volatile oil, and that is to be sprayed onto makeup. [Prior art documents] [Patent documents]

[Effects of the Invention]
[0010] According to the present invention, it is possible to provide a multi-layered cosmetic that is excellent in layer separation at low temperatures, transparency at low temperatures, and film formation speed. DETAILED DESCRIPTION OF THE INVENTION
[0011] Preferred embodiments of the present invention will be described in detail. However, the present invention is not limited to the following preferred embodiments and can be freely modified within the scope of the present invention. In this specification, "%" represents mass % unless otherwise specified. In addition, in this specification, when a numerical range is expressed using "to", the range includes both ends of the numerical range.
[0012] <Component (A) Lipophilic resin> The lipophilic resin used in the present invention (hereinafter also referred to as "component (A) lipophilic resin" or "component (A)") is a resin that is soluble in an oily agent or that swells and disperses uniformly in an oily agent, and is not particularly limited as long as it is one that can be commonly used in cosmetics or topical skin preparations, regardless of its origin, such as a natural resin, semi-synthetic resin, or synthetic resin.
[0013] The component (A) lipophilic resin is not particularly limited, and examples thereof include silicone-based resins such as polymethylsilsesquioxane, polypropylsilsesquioxane, trimethylsiloxysilicate, trifluoroalkyldimethyltrimethylsiloxysilicate, (trimethylsiloxysilicate / dimethiconol) crosspolymer, (dimethicone / vinyltrimethylsiloxysilicate) crosspolymer, (dimethicone / vinyldimethicone) crosspolymer, (vinyldimethyl / trimethylsiloxysilicate / dimethicone) crosspolymer, and (vinyldimethyl / stearyldimethiconetrimethylsiloxysilicate) crosspolymer; (meth)acrylic acid-based resins such as (styrene / acrylates) copolymer and (cyclohexyl methacrylate / ethylhexyl methacrylate) copolymer; Examples of suitable components include (meth)acrylic-silicone graft polymers such as (acrylates / dimethicone) copolymer and (acrylates / polytrimethylsiloxy methacrylate) copolymer; dextrin fatty acid esters such as dextrin isostearate; α-olefin / vinylpyrrolidone copolymers such as (VP / eicosene) copolymer; silicone-modified polysaccharide compounds such as tri(trimethylsiloxy)silylpropylcarbamate pullulan; pullulan fatty acid esters such as myristoylated pullulan and palmitoylated pullulan; rosin acid resins such as rosin-modified phenolic resins and rosin esters; candelilla resins; vinyl acetate resins; saturated or unsaturated hydrocarbon resins such as butene resins such as polybutene resins, polyisoprene resins, and hydrogenated resins thereof; and polyurethane resins. Combining these components (A) with the components described below also facilitates favorable phase separation. One or more of these components (A) can be selected, and combining multiple components is preferred. It should be noted that "(meth)acrylic acid" means "acrylic acid" and / or "methacrylic acid", and "(meth)acrylic" means acrylic and / or methacrylic.
[0014] Furthermore, among the component (A) lipophilic resins, film-forming resins are preferred from the viewpoint of film formation speed. Film formation refers to the process of uniformly applying a resin solution prepared by dissolving a lipophilic resin in a volatile oil to a glass plate to a certain thickness (e.g., 400 μm), and then forming a film after the volatile oil has evaporated.
[0015] From the viewpoint of low-temperature transparency and film-forming speed, the component (A) lipophilic resin is preferably one or more selected from the group consisting of silicone-based resins, (meth)acrylic acid-based resins, (meth)acrylic-silicone graft polymers, and dextrin fatty acid esters. One or more selected from the group consisting of silicone-based resins, (meth)acrylic acid-based resins, and (meth)acrylic-silicone graft polymers is more preferred, with silicone-based resins being particularly preferred. In this embodiment, one lipophilic resin selected from the examples may be used alone, but a combination of two or more is more preferred, as this provides better low-temperature phase separation and transparency. Furthermore, to further improve low-temperature phase separation and transparency, two or more selected from the group consisting of silicone-based resins such as trimethylsiloxysilicate may be used in combination. For example, a combination of (dimethicone / vinyltrimethylsiloxysilicate) crosspolymer and trimethylsiloxysilicate may be used.
[0016] Of the component (A) lipophilic resins, one or more selected from the group consisting of polymethylsilsesquioxane, trimethylsiloxysilicate, (acrylates / dimethicone) copolymer, trifluoroalkyldimethyltrimethylsiloxysilicate, (dimethicone / vinyltrimethylsiloxysilicate) crosspolymer, (trimethylsiloxysilicate / dimethiconol) crosspolymer, (dimethicone / vinyldimethicone) crosspolymer, (styrene / acrylates) copolymer, (cyclohexyl methacrylate / ethylhexyl methacrylate) copolymer, and dextrin isostearate are preferred, and polymethylsilsesquioxane, trimethylsiloxysilicate, (acrylates / dimethicone) copolymer, trifluoroalkyldimethyltrimethylsiloxysilicate, (trimethylsiloxysilicate / dimethiconol) crosspolymer, (dimethicone / vinyldimethicone) crosspolymer, (styrene / acrylates) copolymer, (cyclohexyl methacrylate / ethylhexyl methacrylate) copolymer, and dextrin isostearate are preferred. More preferred are one or more selected from the group consisting of trimethylsiloxysilicate, (dimethicone / vinyltrimethylsiloxysilicate) crosspolymer, (trimethylsiloxysilicate / dimethiconol) crosspolymer, (styrene / acrylates) copolymer, (cyclohexyl methacrylate / ethylhexyl methacrylate) copolymer, and dextrin isostearate, and even more preferred are one or more selected from the group consisting of polymethylsilsesquioxane, trimethylsiloxysilicate, (acrylates / dimethicone) copolymer, trifluoroalkyldimethyltrimethylsiloxysilicate, (dimethicone / vinyltrimethylsiloxysilicate) crosspolymer, and (trimethylsiloxysilicate / dimethiconol) crosspolymer. This results in better layer separation at low temperatures, transparency at low temperatures, and film formation speed. It is more preferable that the component (A) lipophilic resin contains at least trimethylsiloxysilicate, and in this case, trimethylsiloxysilicate may be combined with other lipophilic resins or different silicone resins. Among these, a combination of trimethylsiloxysilicate and polymethylsilsesquioxane, or a combination of trimethylsiloxysilicate and (dimethicone / vinyltrimethylsiloxysilicate) crosspolymer is more preferable, and a combination of trimethylsiloxysilicate, polymethylsilsesquioxane, and (dimethicone / vinyltrimethylsiloxysilicate) crosspolymer is even more preferable. This improves the layer separation properties at low temperatures, transparency at low temperatures, and film formation speed.

The kinematic viscosity of the nonvolatile silicone oil at 25°C is preferably 6 mm from the viewpoint of better mist fineness. 2 / s or more, preferably 6 to 20 mm 2 / s, more preferably 6 to 10 mm 2 / s, and is also preferred from the viewpoint of preventing nozzle clogging after use. The preferred content of non-volatile silicone oils is not particularly limited, but is preferably 1 to 20%, more preferably 3 to 15%, and even more preferably 3 to 10% of the total mass of the multi-layered cosmetic.
[0045] The powder is not particularly limited as long as it is one that is normally used in cosmetics, and examples thereof include inorganic powders such as titanium oxide, zinc oxide, cerium oxide, aluminum oxide, silicic anhydride, calcium carbonate, chromium oxide, chromium hydroxide, konjo, ultramarine, iron oxide, carbon black, mica, synthetic phlogopite, sericite, talc, kaolin, barium sulfate, and boron nitride; nylon, polymethyl methacrylate, polyethylene, polypropylene, polystyrene, silicone resin powder, cellulose and its derivatives, urethane, silk powder, crystalline cellulose, N-acyl lysine; Red No. 201, Red No. 202, and Red No. 22; Examples of suitable pigment powders include organic tar-based pigments such as No. 8, Orange No. 203, Blue No. 404, Yellow No. 401, Red No. 3, Red No. 104, Red No. 106, Orange No. 205, Yellow No. 4, Yellow No. 5, Green No. 3, Blue No. 1, Purple No. 401, and Purple No. 201, as well as their lake pigments; composite powders such as titanium dioxide-coated mica, titanium dioxide-coated mica, zinc oxide-coated mica, titanium dioxide-coated glass powder, and carmine-coated mica; laminated film powders such as polyethylene terephthalate-aluminum-epoxy laminated powder and polyethylene terephthalate-polymethyl methacrylate laminated powder; and aluminum powder, gold powder, silver powder, and other metal powders. These powders may be surface-treated with one or more of fluorine-based compounds, silicone-based compounds, metal soaps, lecithin, hydrogenated lecithin, collagen, amino acids, hydrocarbons, higher fatty acids, higher alcohols, esters, waxes, surfactants, and the like. One or more of these powders may be used. By including this powder, it is possible to make the multi-layered cosmetic composition into three or more layers, as long as the effect of the present technology is not impaired. The content of the powder in the total mass of the multi-layered cosmetic is not particularly limited, but a suitable lower limit is preferably 0.5% or more, more preferably 1% or more, and a suitable upper limit is preferably 10% or less, more preferably 5% or less, and even more preferably 3% or less.
[0046] Examples of antioxidants include α-tocopherol and ascorbic acid; examples of cosmetic ingredients include vitamins, anti-inflammatory agents, and herbal medicines; and examples of preservatives include parahydroxybenzoic acid esters, phenoxyethanol, alkanediols, and chlorphenesin, but are not limited to these, and one or more of these may be used.
[0047] Examples of pH adjusters include lactic acid, citric acid, glycolic acid, succinic acid, tartaric acid, malic acid, or salts thereof (excluding metal salts), potassium carbonate, sodium bicarbonate, ammonium bicarbonate, etc.; examples of cooling agents include L-menthol, camphor, etc., but are not limited to these, and one or more of these can be appropriately selected and used.
[0048] The method for producing the multi-layered cosmetic of the present technology is not particularly limited, and can be produced by a commonly known method. For example, the multi-layered cosmetic of the present technology can be obtained by filling components (A) to (D) and other components into a container (e.g., a container with a dispenser, a container with a spray nozzle, a spray container, a finger spray container, a pressure-accumulating spray container, a mist spray container, etc.). The components used in the present technology may be mixed and then filled. Alternatively, the components used in the present technology may be filled into multiple containers, such as a container for the aqueous layer, a container for the oil layer, and a container for the powder, to form a multi-component product (kit), such as a two-component or three-component product. In the case of a multi-component product, the user can mix the aqueous layer component, oil layer component, powder component, etc. in the desired ratio before spraying. Furthermore, it is preferable to use a transparent or translucent container as the container for filling the multi-layered cosmetic of the present technology. In the present technology, "transparent or translucent" means that the interface of the multi-layered cosmetic inside can be seen. However, the entire container does not need to be transparent or translucent, and a container that allows the contents to be partially visible is also included in the "transparent or translucent" container of this technology.
[0049] The multi-layered cosmetic composition of the present technology is not particularly limited in its application, but is preferably used to protect makeup by spraying it onto the face after applying base makeup such as foundation, or makeup such as eye shadow or blush. It can be used in a container with a spray nozzle or in aerosol form. A spray container with a spray nozzle diameter of approximately 0.1 to 0.6 mm (preferably 0.2 to 0.5 mm) may be used, and a diameter of 0.3 mm can be used for spray evaluation. Since it is used by spraying, it is preferably a liquid cosmetic composition.
[0050] As shown in the Examples below, the multi-layered cosmetic composition of the present technology is a multi-layered composition with at least two layers, including an upper oil layer and a lower water layer, and can also be made into a multi-layered composition with three or more layers by including powder or the like or by using oil layers with different specific gravities. The multi-layered cosmetic composition of the present technology can be well dispersed by mixing immediately before use by spraying, and can maintain this dispersed state for a certain period of time, but will return to a multi-layered structure if left for a certain period of time.
[0051] Furthermore, the viscosity (mPa·s) of the multi-layered cosmetic preparation of the present technology is preferably 1500 mPa·s or less at 25°C when measured as an average value over one minute using a Brookfield viscometer with a No. 2 rotor at 6 rpm, and more preferably 1000 mPa·s or less, as this results in excellent mist fineness.
[0052] The present invention can also employ the following configurations. [1] The following components (A) to (D); (A) Lipophilic resin (B) Volatile oil (C) A polar oil that is liquid at 25°C and has a molecular weight of 370 or less (D)Water The multi-layered cosmetic composition contains the following: [2] The multi-layered cosmetic according to [1], wherein the component (C) is one or more selected from fatty acids and higher alcohols.

[0057] The compounds used in Tables 1 to 3 are shown below. <Lipophilic resin> The lipophilic resin contents listed in Tables 1 to 3 are the amount of solids. Each composition contained the following commercially available products, and the solid content at that time is the amount. Commercially available products that were dissolved or swollen in an oil solution and uniformly dispersed were considered lipophilic resins. When a volatile oil solution or other commercially available resin solution (temperature: 10 to 20°C) was added to a solid content of 10% to 100 mL and stirred, the resulting solution was considered a lipophilic resin. For example, a compound that can be dissolved using any of the oil solutions (e.g., dimethylpolysiloxane) used as a solvent for the commercially available component (A) can be considered a lipophilic resin. The following compounds were considered lipophilic resins. The film-forming ability of resin solutions dissolved in the same oil solution or commercially available resin solutions was evaluated as described above in <Component (A) Lipophilic Resin>. Film formation was observed for all of the following compounds, confirming that they are lipophilic resins with film-forming ability. The following compounds can be used as lipophilic resins in Examples 1 to 30, and the content of the lipophilic resin in Examples 1 to 30 is the amount of solid content.
