Abstract

PURPOSE:To obtain a make-up cosmetic excellent in color in a coated state and covering power by blending a specified amount of a bar-shaped powder and a specified amount of yellow titanium oxide. CONSTITUTION:This make-up cosmetic is obtained by mixing 0.5 to 20 pts.wt. rod-shaped powder and 0.1 to 20 pts.wt. yellow titanium oxide in 100 pts. wt. cosmetic and excellent in color in a coated state and covering power. The rod-shaped powder is preferably selected from titanium oxide, a titanic acid salt, calcium carbonate, silica, alumina, zirconia, halloysite, their composite materials and their surface-treated materials. As the size of the rod-shaped powder, the short diameter, the long diameter and the ratio of the short diameter to the long diameter are preferably 0.005 to 0.2mum, >=0.5mum and 1:10 to 1:1000 respectively. The yellow titanium oxide is preferably selected from an iron oxide-titanium oxide sintered material, titanium oxide coated with iron oxide and titanium oxide doped with iron. Since colored titanium oxide having a relatively low coloring power is used in this method, there is much degree of freedom for blending. In addition, titanium oxide is used as the main component and a high covering power is exhibited.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a make-up cosmetic composition containing a rod-shaped powder and yellow titanium oxide. More specifically, by simultaneously blending a rod-shaped powder that tends to show a slight bluish color when applied to the skin and titanium oxide colored yellow, which is the complementary color of blue, the bluish color is canceled out, and at the same time the coating color is excellent. The present invention relates to a makeup cosmetic having excellent covering power.

[0002]

2. Description of the Related Art Conventionally, rod-shaped powder has been widely used as an additive or reinforcing material for plastics and paints. On the other hand, in cosmetics, as disclosed by the present inventor in Japanese Patent No. 94-448, a technique is known in which attention is paid to the adhesiveness obtained from the shape of the powder itself.

However, rod-shaped powders having a fine particle size of submicron or less as a minor axis have optical characteristics of fine particles even if the major axis has a size of submicron or more. In many cases, the occurrence of paleness upon application to the skin has been a problem.

As a result of diligent study by the present inventor about the method of eliminating the bluishness, the bluishness of the rod-shaped powder is effectively eliminated by simultaneously adding titanium oxide colored yellow which is a complementary color of blue. I succeeded in doing so.

Various methods using this complementary color have hitherto been studied in the development of fine particle titanium oxide. For example, as disclosed in Japanese Patent Publication No. 6-21057, a method of simultaneously mixing fine particle titanium oxide and fine particle iron oxide can be mentioned. Although it is possible to eliminate bluishness by this method as well, when iron oxide, which is fine particles but has relatively strong coloring power, is used, the limit of the amount of iron oxide compounded is low due to the relationship with the tint of the cosmetic. There is a problem. Furthermore, if the blending amount is too small, it cannot be evenly applied to the skin, resulting in a problem that it is difficult to eliminate the paleness.

On the other hand, in the method of the present invention, colored titanium oxide, which has a relatively lower coloring power than iron oxide and the like, is used, and therefore, there is a feature that the degree of freedom of blending is large. further,
Since it is mainly composed of titanium oxide, it also has excellent covering power.

Therefore, an object of the present invention is to provide a make-up cosmetic composition containing a rod-shaped powder and yellow titanium oxide.

[Table 1]

(Manufacturing Method) After mixing the powder components with a Henschel mixer, the liquid components previously mixed are added,
The mixture was further stirred and mixed. Then, after pulverizing with an atomizer, it was punched with a die to obtain a product.

Comparative Example 1 A trial production was carried out in the same manner as in Example 1 except that the rod-shaped powder of Example 1 was changed to fine particle titanium oxide (average primary particle diameter 0.035 μm).

Example 2 It was prepared according to the formulation shown in Table 2. As the rod-shaped powder, titanium oxide (minor axis 0.02 μm, major axis 1 μm) treated with perfluoroalkylphosphoric acid triethanolamine salt 5% was used. The treatment of 5% perfluoroalkyl phosphoric acid triethanolamine salt is abbreviated as fluorine treatment below.
