Powder color cosmetic composition {COLOR COSMETIC COMPOSITION OF POWDER}

The present invention relates to a powdery tonal cosmetic composition, and more particularly, to reduce the color change that actually occurs even if the powder cosmetic film is wetted by sebum secreted after makeup, the first color change is less, and at the same time the persistence of the makeup effect and The present invention relates to powdery color cosmetic composition having excellent usability.

Conventional powder powder colorants are composed of two components of powder-oil, and may be classified into face powder, compact, powder foundation, two-way cake and the like according to the composition ratio, formulation, and purpose of use.

In general, these products are applied to the skin and adhered for about 8 to 12 hours. During this time, a change in the cosmetic film is caused by skin secretions such as sweat or sebum secreted from the skin. These changes are mostly related to sustainability such as lifting, agglomeration, color change, and lumping phenomenon, and the color change phenomenon that occurs when the powdery membrane gets wet due to sebum secreted over time after the double make-up One of the big complaints of women who use it.

In conventional powdery whitening cosmetics, when the makeup coat applied to the face gets wet with secreted sebum over time, color change occurs such as brightness decreases or color tone changes. The cause of the color change is caused by the difference in reflectance when the powder is wet with sebum or the decrease in brightness due to impurities such as iron contained in the white powder, especially the effect of wet color difference of iron oxide by sebum. This is the biggest.

In order to solve the above problems, Japanese Patent Application Laid-Open No. 7-119168 uses iron oxide pigments coated with a fluorine-based surface treatment agent so that the powder does not get wet with sebum due to the fluorine-specific oil repellency, so that the color difference occurs during sebum wetting. Discloses a method for reducing However, the method has a problem in that the powder is not wet due to the feeling of use or formulation, that is, a strong oil repellent property, but is difficult to apply due to the phenomenon that the makeup film itself is swollen. In addition, there has been a method of minimizing powder wetting by formulating powders having excellent oil absorption properties to absorb excess sebum secreted. However, this method also completely absorbs sebum when considering the amount of powder applied to the face and the amount of sebum secreted. There is a problem that it is impossible to prevent the powder from getting wet.

Therefore, there is a need for further research on powdery tincture cosmetics that can reduce the color change during sebum wetting and have a bright and clean makeup effect.

In order to solve the problems of the prior art as described above, the present invention reduces the color change that actually occurs even if the powder cosmetic film is wetted by sebum secreted after make-up, the first color change is less, and at the same time the persistence and feeling of use An object of the present invention is to provide an excellent powder color cosmetic composition.

In order to achieve the above object, the present invention provides a powder tin colorant composition comprising iron oxide pigment coated with 10 to 60 parts by weight of the surface treatment agent.

Hereinafter, the present invention will be described in detail.

The inventors of the present invention while studying the powdery tint cosmetics that can reduce the color change during sebum wetting, which can give a bright and clean makeup effect, by reducing the color difference of iron oxide pigment generated when wet with sebum It was confirmed that the remarkably lowered, and based on this, the present invention was completed.

Powder powder composition of the present invention is characterized in that it comprises iron oxide pigment surface-coated with 10 to 60 parts by weight of the surface treatment agent.

The surface treatment agent used in the present invention is preferably included in 10 to 60 parts by weight, more preferably 10 to 40 parts by weight based on 100 parts by weight of iron pigment. If the content is less than 10 parts by weight, there is a problem that the color change phenomenon is increased during sebum wetting, and if it exceeds 60 parts by weight, there is a problem that the feeling and the formulation is lowered.

The surface treating agent is not particularly limited, but is preferably a silicone polymer or an acrylic polymer.

The silicone-based polymer may be methylhydrogen polysiloxane, methylpolysiloxane, triethoxysilylethyl polymethylsiloxyethyl dimethicone, triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone Triethoxysilylethyl polydimethysiloxyethyl hexyl dimethicone, or n-octyl triethoxy silane can be used.

The acrylic polymer is an acrylates / dimethicone copolymer, an acrylate / tridecyl acrylate / triethoxysilylpropyl methacrylate dimethicone methacrylate copolymer (acrylates / tridecyl acrylate / triethoxysilylpropyl methacrylate dimethicone methacrylate copolymer, alkyl acrylate copolymer, etc. may be used.

The powder powder composition of the present invention comprising the above components is used by changing the color of the pigment used in the color cosmetics in advance to reduce the color difference that is actually generated even if the cosmetic film is wet by sebum secreted after makeup. And the makeup effect is maintained.

Hereinafter, preferred examples are provided to help understanding of the present invention, but the following examples are merely to illustrate the present invention, and the scope of the present invention is not limited to the following examples.
