3) Evaluation of cosmetic durability
After 3 hours, the solid powder cosmetic was applied to the skin by 10 cosmetic panelists, and 3 professional evaluators were evaluated for each evaluation item of "cosmetic change flower evaluation" and "oily light evaluation" on a 10-point evaluation basis based on the following evaluation criteria (very poor cosmetic durability: 0 point, very good cosmetic durability: 10 points). The evaluation average value was calculated and determined as described below, and is represented by a symbol in the table.
[ determination ]
Very good: the average evaluation score is more than 9;
o: the average score of the evaluation was 6 points or more and less than 9 points;
Δ ≈ Δ: the average score of the evaluation was 4 or more and less than 6;
and (delta): the average score of the evaluation was 2 points or more and less than 4 points;
x: the average score of the evaluation was less than 2.
4) Hardness of powder composition
The penetration of the molded body surface was measured using an ASKER durometer (model No. JIS K6031A) to calculate an average value of the number of tests (N) = 5. The average value is preferably in the range of 30 to 100.
In the present specification, the following symbols represent the following meanings.
Very good: excellent;
o: the method is good;
Δ ≈ Δ: acceptance;
and (delta): is not acceptable;

The powder compositions of the examples and comparative examples of table 1 below were evaluated according to the above-described methods. The results are shown in Table 4.
TABLE 4
As shown in table 4, the powder composition obtained by blending the synthetic fluorophlogopite iron and the siloxysilicate in the above-mentioned mass fractions had sufficient impact resistance and was excellent in handling properties.
Compared with the examples, the formula of the comparative example 1 has more mica components, less talc and more mica raw materials, is not suitable for pressing powder, is not easy to form by pressing, is easy to crack in the pressing process, and affects the yield. The formula of comparative example 2 has a large amount of silica, and the powder is easily broken during molding and demolding. Comparative example 3 no organic powder was added, and the ratio of binder components (wax, magnesium myristate) was small, the binding action between powders was weak, and the powder press property and impact resistance were poor. Comparative example 4 had no oil phase interface component added, and lacked the smooth and light feel upon use, also felt powdery feel, and had insufficient durability.
From the above, it is understood that a cosmetic excellent in both of usability, durability and impact resistance can be obtained by the formulation of talc, functional organic powder, siloxysilicate and polydimethylsiloxane in the above mass fractions.
While the invention has been described with reference to specific embodiments, the scope of the invention is not limited thereto, and those skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the invention. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
