Description

The present invention relates to keratin materials, including goniochromatic pigments and white pigments, for example powder compositions for making up the skin, and cosmetic methods using them.

Cosmetic powder compositions for keratin substances are used as makeup cosmetics, such as foundation powders and finishing powders. These compositions are used to impart an attractive appearance to keratin materials. Therefore, for the cosmetic powder composition, in order to play a role as a makeup cosmetic, an aesthetic effect, for example, an effect of imparting a natural finish to the keratin substance, preferably the skin, particularly the skin of the face, a three-dimensional effect. , And a good masking effect is very important. In order to impart such an aesthetic effect to cosmetic powder compositions, it has been proposed to use goniochromatic pigments in the compositions.

For example, JP-A-11-322541 discloses a cosmetic composition comprising a cosmetically acceptable medium; at least one first colorant; and at least one second colorant, wherein the first Is a goniochromatic colorant capable of producing different colors depending on the incident angle of light and the viewing angle, the goniochromatic colorant is a multilayer interference structure, and the second colorant Is disclosed as a monochromatic colorant that produces one of the colors of said goniochromatic colorants.

-Goniochromatic pigment (d): Product name: Relief Color® Pink; this pigment contains 83% by weight of mica, 16% by weight of titanium dioxide, and 1% by weight of iron oxide. The interference color is silver.

As can be seen from the evaluation results of Table 1 (Table 1), the composition according to Example 1 containing the combination of the goniochromatic pigment and the white pigment of the present invention in a specific amount has an excellent three-dimensional effect, a natural finish, And showed a sufficient hiding effect.

On the other hand, the compositions according to Comparative Examples 1 to 3 which did not contain the goniochromatic pigment of the present invention could not sufficiently impart a natural finish or a three-dimensional effect. The composition according to Comparative Example 4 containing the goniochromatic pigment of the present invention but in a small amount could not sufficiently impart the three-dimensional effect and the masking effect. The composition according to Comparative Example 5 containing no white pigment could not impart a hiding effect.

(Example 2)
The composition according to Example 2 was prepared by mixing the ingredients listed in Table 2 and then pressed in a press to give a pressed powder foundation. The composition is shown in Table 2. In Table 2, all constituents are based on "wt%" of the active ingredient.

-Goniochromatic pigment (a): Product name: Duocrome (registered trademark) YR 422C, manufactured by BASF; this pigment contains 52.5 mass% mica, 43.5 mass% titanium dioxide, and 4 mass% Fe ₂ O ₃ . Including. The interference color is red.

Monitor tests confirmed that the composition according to Example 2 was also able to impart three important properties: a pronounced three-dimensional effect, a natural finish, and an excellent hiding effect.

As a result, the powder compositions according to the invention are very suitable for use as makeup powders, such as foundation powders, finishing or face powders, body make-up products, blushers, and eye shadows, especially foundation powders and finishing powders. It can be concluded that it is preferable.
