[Composition]
Eyeshadow compositions according to the Examples and Comparative Examples were prepared by mixing the ingredients listed in Table 1 and then pressed using a press to obtain a pressed powder format. The aluminum flakes used in the examples were silica-coated aluminum flakes sold under the name Velvet Silver® obtained from TOYAL. The average particle size of this pigment is 13 μm. The flake-type black iron oxide used in the examples was a black flake-type iron oxide sold under the name BM-200P® obtained from Titan Kogyo. The average particle size of this pigment is 10 to 20 μm. The black iron oxide coated mica was black iron oxide coated mica flakes sold under the name COLORONA MICA BLACK® obtained from Merck. The average particle size of this pigment is 10 to 60 μm.

The composition is shown in Table 1. In Table 1, all ingredients are based on "% by weight" as active ingredients.

[evaluation]
The compositions according to Examples 1 to 3 and Comparative Examples 1 to 4 were evaluated by 10 monitors with respect to three key properties of spreadability, stereoscopic effect and natural finish. Each composition according to Examples 1 to 3 and Comparative Examples 1 to 4 was applied onto the monitor's eyelid using a brush by the monitor himself. Monitors rated whether they were able to perceive good spreadability, a three-dimensional effect, and a natural finish after application. Table 1 shows how many people recognized each effect.
+++: More than 7 people recognized the effect
++: 4-5 people recognized the effect
+: Fewer than 3 people recognized the effect

As can be seen from the evaluation results in Table 1, the compositions according to Examples 1 to 3 containing the combination of flake-type aluminum pigment and flake-type black pigment exhibited excellent three-dimensional effect, natural finish. , and improved coatability.

On the other hand, the compositions according to Comparative Examples 1 to 4, which do not contain the combination of flake-type aluminum pigment and flake-type black pigment, provide both good stereoscopic effect, natural finish and improved application properties. I couldn't do it.

The compositions according to the invention can therefore be used as make-up powders, such as powder foundations, liquid foundations, finishing powders or face powders, body make-up products, blushers, blushes, lipsticks, eyeshadow primers, facial contouring. , and it can be concluded that it is very favorable for use as an eyeshadow, especially as an eyeshadow.
