[0022] Examples 1 to 6 (Adjustment method) Components (A), (B), (C), colorant, and filler were mixed uniformly in a Henschel mixer, and then components (D), (E), and a mixture of liquid components were added and mixed. The resulting mixture was pulverized in an atomizer. It was then pressed into a metal plate. The resulting solid powder cosmetic compositions were evaluated for the following items. The results are shown in Table 1.

[0023] (1) Stretchiness and unevenness The usability (spreadability on the skin and uneven application) of the cosmetic puff when used without being wetted with water was evaluated according to the following criteria. 5: It spreads very well and there are no uneven areas on the surface. 4: It spreads well and there are almost no uneven areas on the surface. 3: Normal spread and uneven paint application 2: Poor spreading and uneven application 1: Very poor spreading and uneven application

[0024] (2) Close Fit The usability (adhesion to the skin) of a cosmetic puff when used without being wetted with water was evaluated according to the following criteria. 5: Very good adhesion to the skin 4: Good adhesion to the skin 3: Normal skin adhesion 2: Poor adhesion to skin 1: Very poor adhesion to skin

[0025] (3) Softness and moist feeling The softness and moist feeling of a cosmetic puff when used without being wetted with water was evaluated according to the following criteria. 5: Very soft and moist 4: Soft and moist 3: Normal softness and moistness 2: Poor softness and moistness 1: Very poor softness and moisturizing

[0026] (4)Transparency The transparency (the feeling that gives an impression similar to bare skin even after makeup is applied) when using a cosmetic puff without wetting it with water was evaluated according to the following criteria. 5: Very good transparency (looks like bare skin) 4: Good transparency 3: Normal transparency 2: Poor transparency 1: Very poor transparency

[0027] (5) Coverage (good coverage makes uneven skin tone less noticeable after application and helps correct uneven skin tone) 5: Very good coverage 4. Good coverage 3: Normal coverage 2: Poor coverage 1: Very poor coverage

[0028] [Table 1]

[0029] As is clear from Table 1, the solid powder cosmetics of Examples 1 to 6 had good spreadability (spreadability and unevenness) and good skin feel (adherence) when applied, and also had good transparency. Results were equal to or better than those of the products containing plastic beads.

[0030] Comparative Examples 1 to 16 Solid powder cosmetic preparations were obtained in the same manner as in Examples 1 to 6, and then similar evaluations were carried out. The results are shown in Table 2.

[0031] [Table 2]

[0032] As is clear from Table 2, the comparative examples that did not contain component (A) or component (B), the comparative examples that did not contain both component (A) and component (B), and comparative examples 4 to 6 that did not satisfy the contents of component (A) and component (B) received many unfavorable evaluations. Furthermore, comparing Example 6 in Table 1 with Comparative Example 4 in Table 2, when the content of component (A) was 30 to 70 mass% and the content of component (B) was 70 to 30 mass%, when the total content of components (A) and (B) exceeded 15 mass%, many evaluations were negative.

[0033] Example 7, Comparative Examples 17 and 18 Solid powder cosmetic preparations were obtained in the same manner as in Examples 1 to 6, and then similar evaluations were carried out, except that the glass beads were mixed together with component (A), component (C), colorant, and filler. The results are shown in Table 2.

[0034] [Table 3]

[0035] Comparative Examples 17 and 18, which contained glass beads, were inferior to Example 8 in terms of "spreadability / unevenness" and "transparency". This is thought to be because the inclusion of glass beads inhibited the improving effect of the combination of components (A) and (B) on "spreadability / unevenness" and "transparency". Furthermore, compared to Example 7, Comparative Example 17 had an inferior "adhesion" and Comparative Example 18 had no improvement in "adhesion." Therefore, it is considered that at least glass beads are not a component that improves "adhesion." [Industrial Applicability]

[0036] The solid powder cosmetic of the present invention can be used as a powder makeup cosmetic including a powder foundation, pressed powder, solid face powder, blusher, powder eye shadow, powder eyebrow, and powder eyeliner.
