Embodiment 1～5、 comparative example 1

[0157] According to the recipe shown in the following Table 1, each component shown in the column of the oil phase component was dissolved at 80 degreeC for 1 hour, heating, and the oil phase composition was obtained.

[0158] According to the formulation shown in the following Table 1, each component shown in the column of the water phase component was dissolved at 80 degreeC for 1 hour, heating, and the water phase composition was obtained.

[0159] The powder X and the ASTOTS liquid were mixed with the oil phase composition obtained above while maintaining the temperature at 80° C., and stirred using a homogenizer (1400 rpm: revolutions per minutes, the same applies hereinafter).

[0160] Next, the aqueous phase composition was added, and it stirred (5000 rpm) with the homogenizer, and obtained the emulsion.

[0161] A pH adjuster (AMP aqueous solution) was added to the obtained emulsion, and pH adjustment was performed. The emulsion after the pH adjustment was cooled to a...

[0206] For the ingredients listed in Table 2, after mixing the ingredients except the powder by heating and stirring at 80°C, powder X (titanium oxide / silica composite particles) and powders with different oil absorption (powder Body Y and other powders) were mixed using a mortar to obtain a mixed preparation (cosmetic).

[0207] On a hot plate heated to 37° C., 80 mg of the obtained mixed preparation was applied to a heated biological skin (white) (Beaulax) in a square of 4 cm×5 cm, and dried for 1 minute. After drying, 60 mg of a powder foundation (trade name: High Gloss Lasting UV, FUJIFILM Corporation) was rubbed five times in one direction with a puff on the coated surface of the mixed preparation to obtain a sample for evaluation.
