Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-based solid cosmetic containing a brilliant powder, and more specifically, to a metallic appearance not only when applied to the skin or the like but also after molding. The present invention relates to an oil-based solid cosmetic having a pearl appearance.

[0002]

2. Description of the Related Art Conventionally, oil-based lipsticks, eye colors,
For teak and the like, various coloring agents have been studied for the purpose of improving the appearance color, the coloring effect at the time of application, and expanding the color gamut.
Among them, brilliant powders have been widely used since they can impart high chroma and texture to the appearance and coating colors, which cannot be obtained with ordinary coloring pigments. Recently, in order to further improve the properties of glittering powders, not only mica but also powders with excellent transparency such as silica or thin and large particles such as synthetic mica are used as the base powder. Attempts have been made to use it.

[0003]

However, even when these glittering powders are blended into oily lipsticks, eye colors, etc., the appearance of the molded product itself has the same saturation as the glittering powder itself. The texture and metallic texture were not obtained, and it was difficult to do so.

[0004] It is considered that this is because, in the case of oil-based solid cosmetics, the glittering powder is difficult to be uniformly oriented on the surface of the molded product. The reason that the glittering powder is difficult to be uniformly oriented is that the glittering powder is in the lower layer due to the pigment dispersing ability of the oily component used in the base material, the effect of thermal convection of the base generated at the time of melt filling, and the like. It is conceivable that the product is settled on the surface or conversely dispersed uniformly on the base and only a small amount is present on the surface of the molded product.

It is conceivable that the appearance may be made metallic by increasing or decreasing the amount of the glittering powder. However, when the amount of the glittering powder is large, the functional surface and the filling property are significantly reduced. There is a problem that
When the blending amount is reduced, it is naturally difficult to exhibit glitter. For this reason, it is practically difficult to express the glitter on the surface of the molded article by changing the amount of the glitter powder.

[0006] Accordingly, there has been a demand for the development of a technique for giving an oil-based solid cosmetic the same brilliancy as an application color in appearance without causing a problem such as a decrease in usability.

[0007]

Means for Solving the Problems In view of the above circumstances, the present inventors have conducted intensive studies and as a result, have been able to obtain a metallic appearance which could not be obtained conventionally by using a glittering powder which has been subjected to a certain hydrophobic treatment. That an oil-based solid cosmetic having a color can be obtained, and the appearance color of this metallic material in the temperature range at the time of filling, for example, when the melt viscosity is measured using a CSL type stress control rheometer manufactured by Carime Co., Ltd. Was found to be excellent when the melt viscosity was 0.02 Pa · s or more, and the present invention was completed.

[0008] That is, the present invention provides an oily solid cosmetic containing a glittering powder which has been subjected to a hydrophobic treatment and an oil agent, the surface of which has a metallic appearance. Also,
The present invention further provides the above oil-based solid cosmetic containing a coloring pigment in an amount of 0.001 to 2% by mass. Furthermore, the present invention has a melt viscosity in a temperature range of 55 to 100 ° C. of 0.0
The present invention provides the above oil-based solid cosmetic having a pressure of 2 Pa · s or more. The present invention still further provides the above oil-based solid cosmetic substantially free of silicone oil as an oil agent.
