SOLUTION: This gommage cosmetic composition is constituted with a coating resin-containing, non-sticking aqueous solution that has specific properties that the resin components precipitate as if rubber eraser dust, when the aqueous resin solution is applied to skin and then the coated layer is rubbed repeatedly so that it may be rubbed and extended. Gommage means the deed that a creamy or milky cosmetic is applied to face and the coated cosmetic is rubbed off from the face by massaging. This composition converts itself to eraser dust-like solid, when the face skin is massaged, and the dust-like solid includes skin dirt such as sebaceous matters and old horny substance, and the skin dirt and the old horny substance are thereby efficiently and effectively removed. A thermoplastic resin and the like are preferably used as the coating resin.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a new type of cosmetic, a gomage cosmetic. More specifically, the purpose is to remove the stratum corneum layered due to dirt and aging of the skin without damaging the skin, and to synergistically improve the efficacy, effect, and action of external preparations and cosmetics to be used next. The present invention relates to cosmetics.

[0002]

2. Description of the Related Art It is known that in order to maintain healthy skin, it is necessary to always remove the stratified stratum corneum and skin dirt. Due to rough skin or aging, the stratum corneum is excessively stratified as compared with the epidermis layer, and the balance between the surface layer and the stratum corneum which is maintained during healthy skin is lost, resulting in dullness and wrinkles. In addition, clogging of the skin with dirt such as sebum also causes dullness.

[0003] Conventionally, cosmetics intended for removing dirt such as sebum include cleansing agents and packs.

[0004] For products intended to remove keratin, pumice or a file-like jig is used to physically or forcibly scrape or harden keratin to be chemically softened using urea or the like. Similarly, there were methods such as rubbing, but these methods were used only for feet and elbows, and could hardly be called cosmetics.

In other words, cosmetics that can be used on the face or sensitive skin and are intended to remove both stains on the skin and the stratified old stratum corneum have hardly been studied. . In recent years, cosmetics aimed at removing both stains on the skin and the stratified old stratum corneum have been disclosed as gomage cosmetics in Japanese Patent Application No. 9-10 / 1990.
8150 is just published.

[0006]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention, as described above, is that it can be used on the face or sensitive skin without damaging the skin, which has been hardly studied hitherto. The purpose of this study is to develop a cosmetic that aims to remove both the stratum corneum and the old stratum corneum, and to provide a skin-friendly, simple, effective and effective gomage cosmetic.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail. The gomage cosmetic of the present invention is a completely new type of cosmetic exclusively used for performing gomage.
Accordingly, in preparing the present specification of the present application, Japanese Patent Application No. 9-108150 discloses a method for unifying words, interpretations and the like as much as possible.
For reference, comparison or quotation.

[0009] Gomage means a cosmetic act of applying a cream or milky liquid cosmetic to the face and rubbing off the applied cosmetic by rubbing the applied cosmetic. Similar to -108150, it is a novel cosmetic having a form such as an aerosol spray form such as a cream, an emulsion, a gel, or a foam used when performing a gomage, and is a stain such as sebum on the face and an old keratin. The purpose of this is to scrape off like an eraser with the cosmetic.

[0010] The feature of the gomage cosmetic of the present invention is that, when massaged, the content composition itself becomes an eraser scum and precipitates, and the scum-like solid content includes dirt such as skin sebum and old keratin. While trying to remove it efficiently. That is, as a method of use, after applying the gomage cosmetic composition of the present invention to the skin surface, which is the surface to be coated, so as to spread, so as to apply, massaging repeatedly while rubbing, the tatters and eraser are removed. Become scum-like (originally in the component liquid)
In the state of being taken into the resin, dirt and exfoliated stratum corneum due to aging and the like come off.

This will be described in more detail. A great feature of the gomage cosmetic composition of the present invention is that the composition of the present invention is a non-stick aqueous solution containing at least a film-forming resin. The non-fixing aqueous solution containing a film-forming resin referred to in the present application is a uniform solution obtained by dissolving, mixing, emulsifying, etc., the film-forming resin and water (and other solvents as necessary). Aqueous solution with the property of forming a film that adheres and hardens after the film is stretched on the skin that is the surface,
Alternatively, the solvent (e.g., water) volatilizes almost completely from the aqueous solution due to poor adhesiveness (sticking property), and even after drying on the coated surface (skin), the film-forming resin existing in the solution is not applied. It refers to an aqueous solution that has the property of being easily peeled off from the part where it has fallen.

When the gomage cosmetic composition of the present invention is used, since the composition is a non-sticky aqueous solution containing at least a film-forming resin, it is easy to peel off once on the skin after application. By forming a resin film and then massaging it, this film-forming resin is separated from the skin, and is separated from the skin promptly and / or after a while, and then precipitated. The film-forming resin that has been separated and deposited rolls up like an eraser scum and comes out in a small cylindrical shape, so it smoothes over the skin and facilitates massage, and removes dirt on the skin and the old stratum corneum. Since it is rubbed off with the resin, it is possible to perform gomage without burdening the skin.

The film-forming resin itself may be a non-fixing resin, or the film-forming resin may be made non-fixing by adding a plasticizer to the film-forming resin. If the amount of the film-forming resin is too small, it is difficult to form a scum-like film of the eraser, and even if a scum-like film is formed, the removability and the effect are poor. The larger the amount of the film-forming resin, that is, the more the thick film is on the skin, the easier the film is to be peeled off, and the easier it is to produce a scum-like film of an eraser. However, if the amount of the film-forming resin is too large, it depends on the resin to be used. When the amount of the plasticizing agent is slightly excessive with respect to the amount of the film-forming resin, it is easy to form a film that is easily peeled off. When the amount is too small, the effect of the plasticizing agent is small and a film that cannot be peeled off is formed. From this viewpoint, the content of the film-forming resin in the cosmetic composition is preferably from 1.5 to 85% by weight, preferably from 5 to 80% by weight, more preferably from 8 to 70% by weight as a solid content. Taking these factors into consideration, the plasticizer must be at least 1% by weight, preferably 5% by weight, based on the amount of the film-forming resin.
It is better to use above.

The film-forming resin used in the present invention includes polyvinylpyrrolidone, polyvinylpyrrolidone /
Vinyl acetate copolymer, molecular weight 10,000 to 10,000
000 cellulose derivative, methoxyethylene maleic anhydride copolymer, polyvinyl alcohol, polyvinyl acetate, alkyl acrylate copolymer, acrylate / methacrylic ester copolymer, vinyl methyl ether / butyl maleate copolymer Cationized product of vinylpyrrolidone / dimethylaminoethyl methacrylate copolymer, a quaternized derivative of cellulose ether (a cellulose ether such as hydroxyethyl cellulose, methyl cellulose, ethyl cellulose, or hydroxypropyl methyl cellulose; Quaternized by using an agent), hydroxypropyl acrylate / butylaminoethyl methacrylate / octylamide acrylate copolymer, etc. In addition to the synthetic resin polymer compound used in the goods, natural polymers, natural latex can be exemplified synthetic latex. These can be used alone or as a mixture of two or more. As the film-forming resin used in the present invention, it is most preferable to use a thermoplastic resin among these resins in order to improve the releasability during massage (friction).

As the film, a resin that forms a flexible film is preferable. Therefore, it is preferable to use a film-forming resin that is flexible even after the resin itself is cured, to obtain a more preferable gomage cosmetic composition. I can do it. Of course, even if it is a resin that forms a hard film by itself, there is a problem in using a mixture of two or more types or a resin that forms a releasable flexible film with a plasticizer. Does not occur. In practicing the present invention, the selection of what kind of resin (what kind of resin) is appropriate, etc., is determined theoretically and by trial and error, depending on the feeling of use and demand at the time of processing and the relationship with other mixtures. You only have to decide.

Next, the plasticizer used in the present invention will be described. As the plasticizer, in addition to esters such as fatty acid esters and inorganic acid esters, which are generally used as plasticizers for resins, by mixing with the filmable resin to be used, plasticity and flexibility can be obtained. Any component that can provide moisture retention and consequently obtain a plasticizing effect can be used as a plasticizing effect agent.

That is, the plasticizers used in the present invention include inorganic acid esters such as the above-mentioned fatty acid esters such as dimethyl phthalate, diethyl phthalate, dibutyl phthalate, butyl stearate and butyl myristate. In addition to tricresyl acid, tristearyl phosphate, tripalmityl phosphate, etc., higher alcohols such as cetanol, stearyl alcohol, olein alcohol, lauryl alcohol, octyl alcohol, decyl alcohol, ethylene glycol, propylene glycol, dipropylene glycol, butylene glycol, Glycerin, diglycerin, glycols such as polyethylene glycol, and surfactants are preferred.
Among these, surfactants are particularly suitable as plasticizers used in the present invention, since surfactants, such as detergency, penetrability, and foaming property, are effective for gomage cosmetics.

Hyaluronic acids such as sodium hyaluronate; sugar mixtures such as pentavitene; water-soluble collagen; hydrolyzed elastin;
Olive oil, vegetable oil such as grape seed oil, squalene, animal oil such as squalene, methyl polysiloxane,
Examples include mineral oils such as dimethylpolysiloxane, methylphenylpolysiloxane, methylhydrogenpolysiloxane, octamethylcyclotetrasiloxane, and decamethylcyclopentasiloxane such as silicones, and emulsions thereof. Among them, silicone is preferable as the plasticizer used in the present invention because it improves the slipperiness at the time of gomage and reduces the burden of friction on the skin.

As the surfactant which can be used as a plasticizer, various surfactants conventionally used in the field of cosmetics (for example, various surfactants listed on the basis of cosmetic raw materials) can be used. Any of a nonionic surfactant, an anionic surfactant, a cationic surfactant, and an amphoteric surfactant can be used.

As an example of a nonionic surfactant,
Examples thereof include glyceryl monostearate, ethylene glycol monostearate, propylene glycol monostearate, propylene glycol distearate, diethylene glycol monostearate, and monoethanolamide of coconut oil fatty acid. Examples of the anionic surfactant include zinc laurate, magnesium stearate, sodium lauryl sulfate, sodium polyoxyethylene lauryl ether sulfate, and sodium polyoxyethylene lauryl ether phosphate. Examples of the cationic surfactant include stearyltrimethylammonium chloride, distearyldimethylammonium chloride, benzethonium chloride, alkylisoquinolinium bromide, lauryltrimethylammonium chloride, and alkyltrimethylammonium chloride. Examples of the amphoteric surfactant include sodium β-laurylbuminopropionate, betaine lauryldimethylaminoacetate, potassium coconut oil collagen peptide, stearyldimethylamino acid betaine, and glycyrrhetinyl stearate. These surfactants may be used by selecting an optimal surfactant by considering the film-forming resin and other components to be mixed together, or the desired plasticizer effect and foaming state, Use is not required unless the ink is discharged in an effective plasticizer effect or an appropriate foamed state.

As the propellant, conventionally used LPG, dimethyl ether, carbon dioxide, nitrous oxide gas, nitrogen, and HFC such as 134a can be used. The amount of the propellant can be appropriately changed depending on the type of gas used on condition that the propellant is obtained, but is 0.5 to 70% by weight, preferably 1 to 40% by weight in the total amount of the cosmetic composition. % Makes it possible to obtain a product that is easy to use as a gomage.

In order to increase the drying property at the time of use, the frictional property at the time of peeling off, improve the dividing property of the film-forming resin, and improve the feeling of peeling off the fragrance and rags, alcohol is contained in the contents. It is effective to add powder or powder.

As the alcohol used in the present invention, ethyl alcohol or i-propyl alcohol, n-
Lower alcohols having 3 or less carbon atoms, such as propyl alcohol, are preferred. The compounding amount of the alcohol is preferably in the range of 1.0 to 90% by weight in the non-fixing aqueous solution.
With the above, there is a possibility that the skin is damaged.

The powder used in the present invention includes kaolin. Talc, titanium oxide, zinc white, spherical cellulose.
・ Silicon dioxide, magnesium silicate, magnesium aluminum silicate, aluminum silicate, titanium oxide,
Examples thereof include powders of an inorganic mixture composed of a single substance or two or more kinds thereof, and resin powders such as polyethylene powder, spherical acrylic resin, nylon powder, and crystalline cellulose powder. The amount of the powder is preferably in the range of 0.01 to 50% by weight based on the total amount of the gomage cosmetic. If it is less than 0.01% by weight, the effect of adding the powder is not so significant, and if it is more than 50% by weight, the skin may be hurt and the feeling of use is deteriorated.
