Accordingly, (a) goniochromatic pigments can produce different colors depending on the incident angle and viewing angle of light.

Goniochromatic pigments generally have an interference multilayer structure consisting of light-transmissive platelets and a coating of interference pigments on the platelets. Multilayers can change color, hue, and brightness by interference of light rays, and the light rays diffract and diffuse differently depending on the layer. Additionally, the goniochromatic pigments may include one or more absorbing colorants in the coating. In this case, the goniochromatic pigments can represent two distinct colors, "absorption color" that can be produced from the absorbing colorant and "reflection color" that can be produced by reflection from the interference pigment depending on the viewing angle. When the viewing angle is normal, the reflected color of the interference pigment is confirmed. At the scattering angle or viewing angle, the reflection color of the interference pigment is no longer observed, and the absorption color is confirmed. Therefore, the color changes from the reflection color due to interference to the absorption color due to the absorption pigment by the change of the viewing angle from the normal angle to the viewing angle.

On the other hand, the compositions according to Comparative Examples 1 to 3 not containing 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 a three-dimensional effect and a hiding effect. The composition according to Comparative Example 5 containing no white pigment could not impart a hiding effect.

<Example 2>

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

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

It was confirmed by the monitor test that the composition according to Example 2 was also able to impart three important characteristics: a remarkable three-dimensional effect, a natural finish, and an excellent hiding effect.

It is therefore concluded that the powdered composition according to the present invention is highly preferred for use as makeup powders, such as foundation powders, finishing powders or face powders, body makeup products, blushes, and eye shadows, in particular foundation powders and finishing powders. can
