Description

Sheet cosmetic composition

The present invention relates to a sheet-like cosmetic composition, and more particularly to a cosmetic composition further comprising a silica powder in addition to a water-soluble polymer and an ionic polymer having an anionic, cationic, and amphoteric salt forming group, a protective film layer and a cosmetic composition. It is introduced and used between supporting layers to effectively remove each warp and shorten the drying time of the cosmetic composition, so that it can be easily peeled off and cleans pores during peeling, and it has excellent application feeling in use and improves the drying speed with high water content. To a composition.

The cornea, which is a contaminant formed in the pores, fills the pores with keratin formed by the consolidation of fat grains containing the contaminants with sebum, which causes clogged pores and causes various skin diseases. These horns are not easily removed by cleansing the face and are not enough to completely remove keratin deep in the pores by a commonly used face cleanser. Therefore, there is a need for a simple cosmetic sheet for the purpose of effectively removing excessive sebum secretion and cleaning pores.

A method of mixing various base polymers with water-soluble polymers in the cosmetic composition layer to effectively remove the corners of the pores. Although a method of using each compound has been disclosed [Japanese Patent Laid-Open No. 5-97627], this method has an effective aspect in removing the warp, but the drying rate of the cosmetic composition layer is slow, causing pain during peeling and not peeling neatly. There is a disadvantage that the residue remains.

Accordingly, the present inventors have tried to effectively remove the jeonjeonjeon, in particular to improve the drying rate, as a result, containing a silica powder in a specific content range with a water-soluble polymer and an ionic polymer having anionic, cationic, amphoteric salt forming groups By increasing the surface adsorption power of the cosmetic composition layer it was found that each warp is effectively removed to complete the present invention.

Accordingly, the present invention provides a sheet-like cosmetic composition that shortens the time until effective removal and drying of each warp, and easily peels off during peeling, cleans pores, and easily peels off, thereby improving the application speed and improving the drying rate with high water content. There is a purpose.

The present invention comprises a protective film layer that is peeled off during use, a cosmetic material composition layer containing a cosmetic composition and a support layer for supporting the cosmetic composition, the cosmetic material composition layer 30 to 55% by weight of water-soluble polymer and anionic, cationic And a sheet-like cosmetic composition containing 5 to 15% by weight of an ionic polymer having an amphoteric salt generating group and 4 to 10% by weight of silica powder.

The present invention will be described in more detail as follows.

The present invention is to include the ionic polymer in the water-soluble polymer for effective removal of each warp and at the same time by using silica powder to increase the surface adsorption power of the cosmetic composition layer compared to the conventional cosmetic composition to effectively remove the warp, The present invention relates to a cosmetic composition having excellent application feeling when it is easily peeled off by shortening the drying time.

In the present invention, the water-soluble polymer used to effectively remove the horn is used as a polymer having water solubility or swelling property in water and non-aqueous solvent, and having a molecular weight of 100,000 to 1 million. Specific examples of the water-soluble polymer used in the present invention include polyvinylpyrrolidone, polyvinyl alcohol, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, gelatin, methyl cellulose, polyacrylic acid, polyethylene oxide, ethyl cellulose and carboxyl. One or more selected from methyl cellulose. The water-soluble polymer is contained in the cosmetic raw material composition in the range of 30 to 55% by weight. If the content is less than 30% by weight, the coating property with the support layer of the cosmetic composition is lowered. Cause a decrease.

In addition, anionic, cationic or amphoteric polymers are used as the ionic polymer used to effectively remove each warp in addition to the water-soluble polymer, preferably those having a molecular weight ranging from 100,000 to 1 million. As the anionic polymer, one selected from polyacrylic acid, polymethacrylic acid and polystyrene sulfonic acid may be used. Cationic polymers include polydimethylaminoethyl methacrylate, polydimethylaminopropylmethacrylate, polydimethylaminopropylmethacrylamide, polymethacrylamidepropyltrimethylammonium chloride, polymethacryloiloxytrimethylammonium chloride and polydimethylamino Any of styrene can be used. Amphoteric polymers include N-carboxymethyl-N-methacryloyloxyethyl-N, N-dimethylammoniumbetaine and N- (3-carboxymethyl) -N-methacryloamideamide-N, N- Use is made of dimethyl ammonium betaine. These ionic polymers are contained in the cosmetic raw material composition 5 to 15% by weight, if the content is less than 5% by weight of the removal rate before each falls, if it exceeds 15% by weight can remain on the skin or cause pain when removing the cosmetic layer have.

In addition, in the present invention, by containing the silica powder in the substrate consisting of the water-soluble polymer and the ionic polymer to increase the surface adsorption strength of the film to improve the drying rate at a high water content to clean the pores by the effective removal of the warp. As for a silica powder, it is more preferable to use what has a magnitude | size of 1-15 micrometers. Such silica powder is contained in the cosmetic raw material composition at 4 to 10% by weight, and if the content is less than 4% by weight, the drying speed is slowed, and when it exceeds 10% by weight, the drying speed is too fast to crack the cosmetic film. There has been a problem that does not remove the effective jeonjeon occurs.

In addition, a surfactant is added for effective dispersion of the silica powder on a substrate composed of a water-soluble polymer and an ionic polymer, and the surfactant is added within the range of 0.7 to 1.5% by weight in the cosmetic raw material composition. If the added amount is less than 0.7% by weight, phase separation of the makeup layer occurs, so that the effective warp is not removed. If the amount exceeds 1.5% by weight, the adhesion to the skin does not come out, and thus the warp is not effectively removed.

In addition, in the cosmetic raw material composition, moisturizing cosmetic raw materials, sebum absorbing cosmetics, exfoliating auxiliary cosmetics, whitening agents, pigments, pigments, fragrances, anti-inflammatory agents, thickeners, humectants, preservatives, fungicides, It may also contain a pore-reducing agent. As a moisturizing cosmetic raw material, ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol or glycerol is used in the range of 1 to 1.5% by weight. The pore-reducing agent is used in the range of 1 to 2% by weight of hamamelis, carbonic acid, citric acid, lactic acid, zinc oxide, zinc sulfate, allantoin or zinc sulfocarbonate. In addition, fragrances such as mint, lavender, jasmine, and menthol are used within 0.1 to 1% by weight in order to emit a persistent fragrance.

In order to easily use the cosmetic composition as described above in the form of a sheet, a pack product is manufactured by forming a support layer and a protective film layer to support the cosmetic composition. As the protective film layer, a film such as polyester, polypropylene, polyethylene, or nylon may be used to protect the cosmetic composition layer, prevent drying, and facilitate peeling. As the material of the support layer, any material having moisture permeability such as cellulose fibers such as rayon and acetate, natural fibers such as cotton and wool, as well as synthetic fibers such as vinyl chloride, polyester, acrylic, polyethylene, and polypropylene may be used. Can be.

When the sheet-like cosmetic composition having the laminated structure as described above is pressurized using a roller or the like, the components contained in the cosmetic raw material composition layer are laminated to the support layer, thereby being coated on the support layer having flexibility to have excellent flexibility.
