Description

  The present invention relates to a cosmetic.

When only normal powder is blended in cosmetics, the powder becomes wet and mirror-finished due to sweat, sebum, etc. generated on the skin, and it is difficult to maintain the finish immediately after application. For this reason, various cosmetics that do not easily cause makeup loss and have a long makeup have been studied.
For example, cosmetics containing a fluorine compound-treated powder, a fluorine-based oil, fluorine-modified silicone, and the like have been studied (Patent Documents 1 and 2).

Five professional panelists “Familiarity” immediately after applying each W / O makeup base to the skin with their fingers, “No stickiness after application”, “No feeling of tension after application” and “ Evaluate “no unevenness after application” according to the following criteria, and then apply each makeup base and then apply a powder foundation (Sophina Fine Fit Powder Foundation UV, manufactured by Kao Corporation) “Finish with a close feeling of foundation” and “Good foundation of powder foundation” were evaluated according to the following criteria. A result is shown by the integrated value of 5 persons.
4: I think so.
3: I think so.
2: I think so.
1: I don't think so.

Example 8
A liquid foundation having the composition shown in Table 2 was produced in the same manner as in Examples 1 to 7, and “goodness of familiarity” immediately after application with a sponge, “no stickiness after application”, “feeling of tension after application” “Non-uniformity”, “Non-uniformity after application”, “Finish with good adhesion” and “Good makeup” were evaluated. The results are shown in Table 2.
