Description

[Technical Field] 【0001】 This invention relates to emulsified cosmetics. [Background technology] 【0002】 Traditionally, cosmetics that cover skin imperfections and provide a brighter finish have been considered. For example, Patent Document 1 describes a water-in-oil emulsion cosmetic containing a vinyl polymer, boron nitride, and a volatile oil, in which, even after the volatile oil has evaporated, the boron nitride suppresses the aggregation of pigments in the coating film, resulting in a smooth, even, and bright finish to the skin after application. [Prior art documents] [Patent Documents] 【0003】 [Patent Document 1] Japanese Patent Publication No. 2016-88848 [Overview of the project] [Problems that the invention aims to solve] 【0004】 However, conventional cosmetics containing fine titanium dioxide particles and volatile oils had the problem of feeling sticky during application, causing dryness after application, and resulting in a pale, flat finish. [Means for solving the problem] 【0005】 The inventors have discovered that by using a specific composite powder in combination with fine particles of titanium dioxide or zinc oxide and a volatile oil, it is possible to obtain an emulsified cosmetic that is easy to spread during application, does not feel sticky, does not feel dry after application, does not turn bluish-white, and has excellent ability to cover uneven surfaces. 【0006】 The present invention comprises the following components (A), (B), and (C): (A) A composite powder containing spherical silica and titanium oxide, with a volume-average particle size of 1 to 50 μm.

[Examples] 【0048】 Examples 1-6, Comparative Examples 1-3 Water-in-oil emulsion cosmetics (makeup bases) with the compositions shown in Table 1 were manufactured, and their ease of application, lack of stickiness during application, lack of dryness after application, and coverage of unevenness were evaluated. The results are also shown in Table 1. 【0049】 (Manufacturing method) At 25°C, a water-in-oil emulsion cosmetic was produced by adding powder components (A) and (B) to an oil phase component (C), dispersing them, and then adding an aqueous phase component and stirring with a homomixer. 【0050】 (Evaluation method) (1) Ease of spreading on the skin: Five expert panelists conducted a sensory evaluation of each makeup base product, assessing its ease of application and spreadability on the skin according to the following criteria. The results are shown as the total scores from the five panelists. 5; It spreads very evenly on the skin. 4; It spreads evenly on the skin. 3; It spreads relatively evenly on the skin. 2; It doesn't spread very evenly on the skin. 1. It doesn't spread evenly on the skin. 【0051】 (2) No feeling of stopping during application: Five expert panelists evaluated each makeup base on the skin based on the following criteria, assessing how easily the product could be applied (how smoothly the fingers could glide over it). The results are shown in the total score from the five panelists. 5; The fingers glide very smoothly during application. 4; The fingers glide smoothly during application. 3; The finger glides slightly smoothly during application. 2; The finger tends to get stuck while applying the product, and it doesn't glide very smoothly. 1. The finger gets stuck while applying the product, and it doesn't glide smoothly. 【0052】 (3) No feeling of dryness after application: Five expert panelists applied each primer to their skin and then sensory-evaluated the dryness of the skin according to the following criteria. The results are shown as the total score from the five panelists. 5; Does not feel dry. 4. The feeling of dryness is not very noticeable. 3; The dryness is somewhat noticeable. 2; The dryness is noticeable. 1. The dryness is quite noticeable. 【0053】 (4) Coverage of unevenness: Five expert panelists applied each primer to their skin and then sensory-evaluated its ability to cover skin imperfections according to the following criteria. The results are shown as the total score from the five panelists. 5; Skin texture is less noticeable. 4. Skin texture is less noticeable. 3; Skin texture is somewhat noticeable. 2; Skin texture is noticeable. 1; The unevenness of the skin is quite noticeable. 【0054】 [Table 1] 【0055】 Example 7 Water-in-oil emulsion cosmetics with the compositions shown in Table 2 were prepared in the same manner as in Examples 1 to 6. The resulting water-in-oil emulsion cosmetic is easy to spread on the skin, does not feel sticky during application, does not feel dry after application, and has excellent coverage of uneven skin texture. 【0056】 [Table 2]
