Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid powder cosmetic obtained by mixing a cosmetic base material and a solvent, filling the mixture into a container, and removing the solvent. The present invention relates to a solid powder cosmetic containing a composite coloring pigment encapsulated in a solid powder, and more particularly to a solid powder cosmetic which suppresses elution of a coloring component without impairing high chroma and high color development.

[0002]

2. Description of the Related Art Conventionally, a press molding method has been generally used as a method for filling and molding a solid powder cosmetic. However, in the press molding method, air tends to remain inside the molded product, and this may cause quality problems such as strength reduction, peeling, and chipping. In addition, this problem was remarkable in three-dimensional molding, a case where a pattern was formed on the press surface, and the like. For this reason, as a molding method for solving such problems, a method has been developed in which a cosmetic base material composed of powder and an oil agent is mixed with a solvent, filled into a container, and then the solvent is removed to obtain a solid cosmetic. It has been applied.

[0003]

However, some tar-based pigments, which are coloring components conventionally used in solid powder cosmetics, have a property of eluting in a solvent. In some cases, this property greatly deteriorates the appearance quality of the molded product. That is, when a large amount of the tar dye is eluted into the solvent, the eluted components are concentrated on the surface of the molded product, etc. with the removal or drying of the solvent. And the internal colors are extremely different from each other. Therefore, conventionally, in such a case, the use of a tar dye having a high elution property to a solvent has been avoided. However, avoiding the inclusion of tar dyes
It is difficult to obtain solid cosmetics with high chroma and high color development, especially for products that require high color saturation and high color development in appearance, such as eye color and blush, and can satisfy the required quality in the market. Did not. Further, a method of coating a coloring component with a silicone compound, a fluorine compound, or the like has also been attempted, but it is impossible to completely cover the tar-based dye, and elution to a solvent cannot be completely suppressed. .

[0004]

Means for Solving the Problems The present inventor has made intensive studies in view of the above situation, and as a result, obtained by mixing a cosmetic base material and a solvent, filling the mixture in a container, and removing the solvent. In a solid powder cosmetic, by containing a composite coloring pigment in which a coloring component is contained in an inorganic compound,
They have found that a solid powder cosmetic having high chroma, high color appearance and coating color and excellent moldability can be obtained, and have completed the present invention.

That is, according to the present invention, in a solid powder cosmetic obtained by mixing a cosmetic base material and a solvent, filling the container, and removing the solvent, the coloring component is encapsulated in an inorganic compound. The present invention provides a solid powder cosmetic containing the composite color pigment. Furthermore, a composite color pigment that is a porous colorant in which the coloring component is sealed in the voids of the porous silica, or a composite coloring pigment in which the coloring component is sealed in a state in which the coloring component is not fixed to the hollow portion of the inorganic compound having the hollow portion, Alternatively, the present invention provides the solid powder cosmetic containing a composite color pigment in which a color component is encapsulated on the surface of an inorganic pigment using calcium carbonate, and a composite color pigment in which the color component is a tar dye. It is.
