Description

The present invention relates to a new type of cosmetic, a gomage cosmetic. More specifically, the purpose is to remove the stratum corneum layered by 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.

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

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

For products intended to remove keratin, use a pumice stone or file-like jig to physically or forcibly scrape or harden hardened keratin chemically with urea, etc. Although there were methods such as rubbing, these were used only for the feet and elbows, and could hardly be called cosmetics.

In other words, cosmetics that can be used on the face and sensitive skin and are intended to remove both dirt on the skin and the stratified old stratum corneum have hardly been studied. In recent years, Patent Document 1 has been disclosed as a gomage cosmetic as a cosmetic for the purpose of removing both soil stains and an overlying old stratum corneum.
JP-A-10-287542

The object of the present invention, as described above, is to be used on the face and sensitive skin parts, which has not been considered so far, without damaging the skin, and removes both the skin dirt and the stratified old stratum corneum The purpose of this study is to develop and develop a cosmetic product that is gentle on the skin, simple, effective, and effective.

The gomage cosmetic composition of the present invention has the following effects, as can be seen from the description in the above examples. That is, by implementing the present invention, a gomage cosmetic composition having an excellent gomage function and having excellent detergency for removing instantaneous dryness, skin burden, workability, and effectively removing dirt such as sebum and old keratin. Can be obtained. In addition, the use of the gomage cosmetic composition imparts a slippery feeling and a transparent feeling to the skin, and improves cosmetic paste. Further, the gomage cosmetic composition of the present invention, although slightly different depending on the formulation, gives a refreshing skin smooth feeling that does not need to be washed off with water or hot water. Therefore, it can be used as a gomage cosmetic suitable for use in places without water or outdoors. In addition, it can be used as a skin cleanser in places where there is no water or outdoors.

Hereinafter, the present invention will be described in detail. The gomage cosmetic of the present invention is a completely new type of cosmetic exclusively used for performing gomage. Therefore, in preparing the specification of the present invention, Japanese Patent Application No. 9-108150 was referred, compared, or quoted in order to unify the words, interpretation, and the like as much as possible.
Gomage refers to a cosmetic action in which a cream or milky cosmetic is applied to the face, and the applied cosmetic is rubbed off by massaging the applied cosmetic. A new cosmetic having a form such as an aerosol spray form such as a cream, an emulsion, a gel, or a foam used when performing the treatment, together with the cosmetic such as dirt such as sebum on the face and old keratin. The purpose is to scrape off like a piece of eraser.

The feature of the gomage cosmetics of the present invention is that, when massaging, the content composition itself becomes an eraser scum, and precipitates out, while entrapping dirt such as sebum of skin and old keratin into the scum-like solid. It tries to remove it efficiently. That is, as a method of use, the gomage cosmetic composition of the present invention is applied to the skin surface, which is the surface to be coated, so that it is spread and spread, so that it is massaged several times while rubbing, so that the tatters and eraser are removed. The dirt and the stratum corneum stratified due to aging and the like are peeled off in the state of being taken in by the resin in the form of residue (originally contained in the content component liquid).

This will be described in more detail. A major 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 formed by dissolving, mixing, emulsifying, etc., the film-forming resin and water (and other solvents as necessary). An aqueous solution that forms a film that adheres and hardens and cannot be removed after the film is spread on the surface of the skin, or the adhesiveness (sticking property) is weak, and most of the solvent such as moisture evaporates from the aqueous solution. An aqueous solution having such a property that the film-forming resin existing in the solution can be easily peeled off from the coated portion even after drying on the coated surface (skin).

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, after application, a non-sticky resin film which is easily peeled off once on the skin is formed. This film-forming resin is formed on the skin and / or after a short period of time by massaging, and is separated from the skin and deposited while curling. The film-forming resin that has been separated and precipitated 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. As it is rubbed off with the resin, it is possible to perform gomage without straining 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 or the like 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 an 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 easy to peel off. When the amount is too small, the effect of the plasticizing agent is small and a film that does not peel off is formed. From this viewpoint, the content of the film-forming resin in the cosmetic composition is preferably 1.5 to 85% by weight, preferably 5 to 80% by weight, and more preferably 8 to 70% by weight as a solid content. In consideration of these factors, the plasticizer must be used in an amount of 1% by weight or more, preferably 5% by weight or more based on the amount of the film-forming resin.

Examples of the film-forming resin used in the present invention include polyvinylpyrrolidone, polyvinylpyrrolidone / vinyl acetate copolymer, cellulose derivatives having a molecular weight of 10,000 to 10,000,000, methoxyethylene maleic anhydride copolymer, polyvinyl alcohol, and poly (vinyl alcohol). Vinyl acetate, alkyl acrylate copolymer, acrylate / methacrylate copolymer, vinyl methyl ether / butyl maleate copolymer, vinyl pyrrolidone / dimethylaminoethyl methacrylate copolymer cationized product, cellulose ether 4th Graded derivatives (eg, cellulose ethers such as hydroxyethylcellulose, methylcellulose, ethylcellulose, hydroxypropylmethylcellulose, and cations such as glidyltrimethylammonium chloride) Quaternized using a chemical agent), hydroxypropyl acrylate / butylaminoethyl methacrylate / octylamide acrylate copolymer, as well as synthetic resin polymer compounds used in general cosmetics, natural polymers, natural polymers, Latex, synthetic latex and the like can be exemplified. 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, since it improves the releasability during massage (friction).

Since a resin that forms a flexible film is preferable as the film, it is possible to obtain a more preferable gomage cosmetic composition by using a film-forming resin that is flexible even after the resin itself is cured. Of course, even if a resin alone forms a hard film, there is a problem in using a mixture of two or more types or a resin that forms a peelable flexible film with a plasticizer. Does not occur. In practicing the present invention, the selection of what type of resin (what nature) is appropriate, etc., is determined theoretically and by trial and error, depending on the feeling of use and demand during 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, as the plasticizer used in the present invention, the above-mentioned fatty acid esters, for example, dimethyl phthalate, diethyl phthalate, dibutyl phthalate, butyl stearate, butyl myristate and the like, inorganic acid esters such as tricresyl phosphate, In addition to 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, di Preferred are glycols such as glycerin and polyethylene glycol, and surfactants. Among these, surfactants are particularly suitable as plasticizers used in the present invention because the surfactants inherent functions such as detergency, permeability and foaming property are effective for gomage cosmetics.

In addition, hyaluronic acids such as sodium hyaluronate, sugar mixtures such as pentavitene, water-soluble collagen, hydrolyzed elastin, etc .; And mineral oils such as silicones such as dimethylpolysiloxane, methylphenylpolysiloxane, methylhydrogenpolysiloxane, octamethylcyclotetrasiloxane, and decamethylcyclopentasiloxane, 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 that can be used as the 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 amphoteric surfactants, anionic surfactants, cationic surfactants, and amphoteric surfactants can be used.

Examples of the nonionic surfactant 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 β-laurylbuminopropionate sodium, lauryldimethylaminoacetate betaine, coconut oil fatty acid collagen peptide potassium, stearyldimethylamino acid betaine, and glycyrrhetinyl stearate. These surfactants may be selected and used depending on the film-forming resin and other components to be blended together, or the desired plasticizer effect and foaming state in consideration of the optimum surfactant. It is not necessary to use it unless it is discharged in an effective plasticizer effect or an appropriate foamed state.

As the propellant, conventionally used LPG, dimethyl ether, carbon dioxide gas, 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.

Alcohol or powder in the contents is used to increase the drying property during use, the frictional properties when peeling off, improve the separability of the film-forming resin, and improve the feeling of peeling off rags and tatters. It is effective to add

As the alcohol used in the present invention, a lower alcohol having 3 or less carbon atoms such as ethyl alcohol, i-propyl alcohol, and n-propyl alcohol is preferable. The amount of the alcohol is preferably in the range of 1.0 to 90% by weight in the non-fixing aqueous solution. When the amount is less than 1% by weight, the effect of adding the alcohol is insufficient, and when the amount is more than 90% by weight, the skin may be damaged. Occurs.

The powder used in the present invention includes kaolin. Talc, titanium oxide, zinc white, spherical cellulose.・ Resin powders such as silicon dioxide, magnesium silicate, magnesium aluminum silicate, aluminum silicate, titanium oxide, etc., alone or in combination of two or more inorganic powders, polyethylene powder, spherical acrylic resin, nylon powder, crystalline cellulose powder, etc. Can be exemplified. 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.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples. In addition, the compounding amount represents weight%.
