Make-up cosmetic composition containing silica hybrid color pigments and the preparing method

The present invention relates to a makeup cosmetic composition containing a silica composite pigment and a manufacturing method thereof, and more particularly, to a makeup cosmetic composition containing a composite pigment coated with silica on the surface of an inorganic pigment and a method for producing the same.

In the case of the conventional powder makeup cosmetics, the color of the extender pigment is changed by sebum or sweat, or the pigment is grayed out over time, thereby deteriorating the makeup effect on brightening.

In order to improve such a cosmetic effect, sieving pigments such as mica and talc, titanium oxide and iron oxide were surface-treated or synthetic mica was used to remove impurities. However, although most pigments are used by surface treatment, the surface treatment material is non-uniform or has a property of absorbing sebum when the surface treatment material is skin-friendly, so there is a limit to maintain the brightness of the makeup effect.

Accordingly, the present inventors have studied to prepare a makeup cosmetic composition having a makeup lasting effect, that is, a brightening effect, by using the surface of the inorganic pigment coated with silica having high oil absorption ability, thereby solving the above problems. It confirmed and completed this invention.

Accordingly, it is an object of the present invention to provide a makeup cosmetic composition having an excellent effect of maintaining the brightness of makeup by containing an inorganic pigment coated with silica.

In order to achieve the above object, the present invention provides a makeup cosmetic composition containing a silica composite pigment coated on the surface of the inorganic pigment with silica.

Since the silica composite pigment contained in the composition of the present invention has a complexed silica compound on the surface of the inorganic pigment to increase sebum oil absorption, it is excellent in effect of maintaining the brightness among the effects of makeup by adjusting the degree of discoloration of the color. Therefore, the cosmetic composition of the present invention is excellent in correcting skin color problems such as acne marks, blemishes, freckles, and dullness, and skin defects such as pores and wrinkles, exhibits a three-dimensional appearance on the skin, and provides an improved feeling of use. do.

The present invention provides a makeup cosmetic composition containing a composite pigment, wherein the surface of the inorganic pigment is coated with silica.

The inorganic pigment used in the present invention is at least one selected from the group consisting of titanium oxide, iron oxide, zinc oxide, zirconium oxide, tin oxide and ultramarine, and as iron oxide, red iron oxide (Fe ₂ O ₃ ), black iron oxide (Fe ₃ O ₄ ) or yellow iron oxide (FeOOH) can be used.

In addition, the silica coating the inorganic pigment is not particularly limited, and can be used commonly used in the industry.

In the present invention, the silica composite pigment comprises 80 to 90% by weight of the inorganic pigment and 10 to 20% by weight of silica based on the total weight of the silica composite pigment. In addition, the silica composite pigment is preferably contained 0.5 to 30% by weight based on the total weight of the cosmetic composition. This is because when the content of the interference color pigment in the makeup cosmetic composition is less than 0.5% by weight, the effect cannot be sufficiently exhibited, and when it exceeds 30% by weight, problems in formulation may occur.

In addition, the sebum oil absorption of the silica composite pigment in the makeup cosmetic composition of the present invention is preferably 0.4 ~ 0.8g / g. This is because if the oil absorption amount of the composite pigment is less than 0.4g / g, the oil absorption amount becomes less and dull due to the sebum oil absorption, and when it exceeds 0.8g / g, it is blended in the cosmetics, causing a feeling of gritty, rough feeling and bluish color. Therefore, it is preferable to limit the oil absorption in the above range.

The silica composite pigment used in the present invention prevents the iron oxide from discoloring because the silica absorbs sweat and sebum, thereby improving the appearance of dull makeup and maintaining the brightness. In addition, it corrects skin color problems such as acne scars, blemishes, freckles, dull skin, pores, wrinkles and the like and provides a three-dimensional effect on the skin.

Makeup cosmetic composition of the present invention may be formulated into a powder-like composition, such as two-way cake, fact, powder, eye shadow. Various bases and additives necessary for each formulation may be appropriately contained, and the type and amount of these components can be easily selected by those skilled in the art.

Makeup cosmetic composition containing a silica composite pigment of the present invention, the first step of producing a composite pigment coated with a silica oxide surface; A second step of grinding and mixing cosmetic ingredients such as oil-soluble oils, binders, sunscreens, preservatives, fragrances; And a third step of adding the composite pigment prepared in the first step to the mixture ground in the second step.

The composite pigment coated with the surface of the iron oxide according to the present invention may be prepared by the following method, but is not limited thereto.

First, at least one inorganic pigment selected from red iron oxide (Fe ₂ O ₃ ), black iron oxide (Fe ₃ O ₄ ), or yellow iron oxide (FeOOH) is added to an aqueous solution. Then, the inorganic pigment is added to an aqueous solution in which one or more silane alkoxides such as sodium silicate (Na ₂ SiO ₃ ), tetraethoxy silan, and tetrabutoxysilane are dissolved. When the acid catalyst is added to hydrolyze and the pH of the aqueous phase is adjusted to be in the range of 4 to 7, a silica coating layer is formed on the iron oxide surface. Subsequently, the resultant on which the silica coating layer is formed is filtered and dried, and sintered and pulverized to obtain a composite coated inorganic pigment. It is preferable to process a sintering process at 600 degreeC-1000 degreeC for about 1 to 5 hours.

Hereinafter, the present invention will be described in more detail with reference to Preparation Examples and Comparative Preparation Examples, but the present invention is not limited only to these examples.
