Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a powdered HM-made shield coloring agent exhibiting an iris color, and in particular to a powdered coloring agent of this kind that does not contain harmful dyes.

Traditionally, as color-enhancing pigments for metallic luster, aluminum powder, bronze powder, and powder called glitter, which is made by adding color to a film made by vapor-depositing a nine-pronged metal with dye and cutting it finely, are also used. . However, aluminum powder
The color of bronze powder and pearl essence is limited to a single color of silver, gold, or white silver, respectively.

Glitter can produce any color by gradual coloring, but it has poor light resistance and the luster will not fade if it is darkened.In addition, Glitter contains metals such as chromium and cobalt, which are called alloy dyes in Eishina. It has drawbacks such as the necessity of using harmful dyes.

Therefore, an object of the present invention is to provide a powder eyebrow shade that exhibits complex and beautiful colors without using dyes that are harmful to the human body.
