Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition, and more particularly to an overcoat cosmetic composition for eye make-up, which is useful for preventing the makeup of the eye make-up cosmetic composition from collapsing.

[0002]

2. Description of the Related Art Eye makeup plays an important role in forming an image of a person's appearance. Among them, the shape of the eyebrows is one of the factors that have a great influence, and for this reason, eyebrow make-ups have been widely performed since ancient times, such as shaving the eyebrows and drawing them artificially. Even in modern times, it is widely practiced to shave the eyebrows or remove the eyebrows and then draw the eyebrows with an eyebrow pencil or the like. The eyebrow pencil used for making up such eyebrows uses an oil gel having a relatively high hardness because the eyebrows must be drawn finely. Thus, in order to increase the hardness, a dosage form containing a high concentration of wax is used, but such a system has a drawback in that the adhesive force to the skin is weak and makeup is easily broken. For this reason, portability was improved, and there was no choice but to regularly make-up. It has been desired to develop a means for improving the makeup lasting effect of such eyebrow. The situation is the same for other eye makeup such as eye color, eyeliner, and mascara, and it has been desired to develop a means for improving makeup lasting throughout the eye makeup.

On the other hand, up until now, a makeup cosmetic is covered with a specific cosmetic from above to improve the makeup lasting,
So-called overcoat cosmetics were developed for lipsticks to prevent color transfer to cups, cigarettes, etc., but overcoat cosmetics for the purpose of preventing makeup loss are also
The overcoat cosmetics for eye makeup were not known at all. Also, I didn't even have such an idea.
Of course, there was no known overcoat cosmetic for eye makeup, which was characterized by containing a water-insoluble polymer and / or a hydrophobic polymer.

[0004]

SUMMARY OF THE INVENTION The present invention has been made under the circumstances as described above, and includes an eye color, an eyeliner,
An object of the present invention is to provide a means for improving the makeup retention of eye makeup cosmetics such as mascara and eyebrow.

[0005]

[Means for Solving the Problems] In view of such a situation, the present inventors have earnestly made research efforts for means for improving the makeup lasting of eye make-up cosmetics such as eye color, eyeliner, mascara, and eyebrow.

BEST MODE FOR CARRYING OUT THE INVENTION The eye make-up overcoat cosmetic of the present invention is characterized by containing a water-insoluble polymer and / or a hydrophobic polymer. Here, the water-insoluble polymer means a polymer which is substantially insoluble in water or is not softened by water, and specifically may have an alkyl acrylate, an alkyl methacrylate, or an alkyl group. Preferable examples are one or more polymers or copolymers selected from styrene and alkylene. These are preferably contained in the form of emulsion by emulsion polymerization or the like. Such a polymer can be obtained by dispersing the above-mentioned monomer in a water-based solvent together with a surfactant, a polymerization initiator and the like and polymerizing. Such a water-insoluble polymer can be used without particular limitation as long as it is usually used in cosmetics, and as a copolymer, even if it is an ordinary random copolymer, the graft copolymer is used. It may be a combination, a block copolymer, or a core / shell type copolymer. Particularly preferred is an alkyl acrylate copolymer emulsion and / or an alkyl acrylate / alkyl methacrylate / methylstyrene copolymer emulsion. Such a polymer may be produced according to the above-mentioned means and used, or a commercially available one may be used. Preferred commercial products include polyjoint JN (alkyl acrylate copolymer emulsion; resin content 50% by weight) manufactured by Taisei Kako Co., Ltd. and EmmaPoly CN sold by Nikko Chemicals Co., Ltd.
(Alkyl acrylate / alkyl methacrylate / methylstyrene copolymer emulsion; resin content 59% by weight). These may contain only one kind, or may contain two or more kinds in combination.
When such a water-insoluble polymer is used in the overcoat of the present invention, the content thereof is preferably 1 to 20% by weight in terms of resin content based on the total amount of the cosmetic, and more preferably, It is 3 to 10% by weight.

Further, the hydrophobic polymer is required not only to be insoluble in water but also to have a property of repelling water and fats and oils. Examples of the polymer having such characteristics include fat and oil perfluoropolyether, and fluoroalkyl-modified alkylpolysiloxane in which a part of the alkyl group of alkylpolysiloxane is replaced with a fluoroalkyl group. In the latter case, the alkyl group preferably has 1 to 10 carbon atoms.
Such a fluoro-modified alkylpolysiloxane can be produced by reacting an alkylpolysiloxane that leaves a reactive hydrogen atom with a silane coupling agent such as dimethylfluoroalkylmethoxysilane to perform fluoroalkyl modification. Among these, perfluoropolyether can be preferably exemplified. Commercially available products of this kind already exist, and among these commercially available products, the preferred product is Hombrin HC /
04 can be illustrated. When such a hydrophobic polymer is contained in the cosmetic of the present invention, it is preferably 80% by weight or more, more preferably 85% by weight or more because of its limited compatibility. When such a perfluoropolyether is used in the overcoat cosmetic of the present invention, silica, calcium silicate, magnesium silicate, calcium carbonate, crystalline cellulose, bentonite and methylsiloxane are used for the purpose of improving the adhesion. It is preferable to contain 1 type or 2 types or more selected from the network polymer in an amount of 1 to 10% by weight, and more preferably 2 to 7% by weight.

The cosmetic of the present invention is the above-mentioned essential ingredient,
In addition to the water-insoluble polymer and / or the hydrophobic polymer, any component usually used in cosmetics can be contained. Such optional components include, for example, hydrocarbons such as squalane, petrolatum and microcrystalline wax, silicones such as dimethicone and femethicone, cross-linked methyl polysiloxane, jojoba oil, bezel wax, carnauba wax, olein. Esters such as acid octyldodecyl, triglycerides such as olive oil, beef tallow, and coconut oil, fatty acids such as stearic acid, oleic acid, and lithinoleic acid, oleyl alcohol, stearyl alcohol, higher alcohols such as octyldodecanol, polyethylene glycol, glycerin, Polyhydric alcohols such as 1,3-butanediol, sorbitol, maltitol, fatty acid monoglyceride, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene fat Esters, nonionic surfactants such as polyoxyethylene alkyl ethers,
Examples include thickening / gelling agents, antioxidants, ultraviolet absorbers, coloring agents such as organic pigments, preservatives, powders such as titanium dioxide, iron oxide, titanium mica, colored titanium mica, and iris foil. it can. Among these, particularly preferable are polyhydric alcohols when they contain only a water-insoluble polymer, and among them, 1,2-pentanediol, isoprene glycol and 1,3-butanediol are selected. Preferable examples are two or more kinds. This is because such a polyhydric alcohol serves as a preferable plasticizer for a film that does not cause makeup deterioration, and has an action to prevent microbial contamination which is a problem when a polymer emulsion is used in cosmetics. Is. The preferable content of these is 1 to 10% by weight, and more preferably,
It is 2 to 7% by weight. This is because if it is too small, the plasticizing action and antimicrobial action may be impaired, and if it is too large, the formation of the coating film itself may be impaired. When such a polyhydric alcohol is used, it is preferable to use phenoxyethanol together, because the antimicrobial property is further improved. The preferred content of phenoxyethanol is 0.1 to 1.5% by weight based on the total amount of the cosmetic.

The overcoat cosmetic for eye make-up of the present invention can be produced by treating the above-mentioned essential components, optional components and preferred components according to a conventional method. The overcoat cosmetic for eye make-up of the present invention is applied with eyebrow, eye color, eyeliner or mascara, and then is applied thereon, and a film of the overcoat cosmetic for eye make-up of the present invention is applied to the eyebrow,
It has the effect of preventing the makeup of the eye color, eyeliner or mascara from being damaged by sweat or sebum. By using the overcoat cosmetic for eye make-up of the present invention, even a cosmetic having a high wax content and thus having low adhesion to the skin can be adhered and fixed by the overcoat of the cosmetic of the present invention. Can be done. This can prevent makeup breakdown. The eye makeup cosmetic to which the overcoat cosmetic for eye makeup of the present invention is applied is not particularly limited, and for example, is applied to commonly known dosage forms such as emulsion type, oil gel type and solvent dispersion type. it can. As a guideline for the content of the wax component, one containing 10 to 70% by weight of the total amount of the eyebrow is preferable. Among these, it is particularly preferable to use as an overcoat cosmetic for eye makeup of oil gel type cosmetics in which the problem of makeup breakage is particularly remarkable. Thus, by applying the coating film of the overcoat cosmetic for eye makeup of the present invention on the eye makeup cosmetic with a large amount of wax, the eye makeup can be fixed, and makeup is destroyed by sebum or sweat. You can prevent things.
