Here, the makeup feel refers to a natural finish with sufficient covering power and a transparent feel. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The component (A) used in the present invention is a non-volatile silicone oil that is incompatible with squalane. Non-volatile means that the mass loss rate after spreading 1g of oil on a 48mm diameter glass petri dish and leaving it at 25℃ and normal pressure for 24 hours is 1% or less.

[0064] (2) Lack of secondary adhesion to a towel after 8 hours of application to the skin: Five expert panelists applied each foundation to the skin, and after 8 hours, they pressed a cotton towel against the skin to evaluate whether the foundation transferred to the skin or not, according to the following criteria. The results were expressed as the total score of the five panelists. 5;Even when I press a towel against my skin after applying the foundation, none of it comes off. 4; Even when I press a towel against my skin after applying the foundation, the foundation doesn't come off. 3; Even when I press a towel against my skin after applying the foundation, not much of it comes off. 2;When you press a towel against your skin after applying the foundation, some of it will stick to it. 1; After applying the foundation, press a towel against your skin and the foundation will stick to it.

[0065] (3) Skin brightness after 8 hours of application: Each foundation was applied to the skin by five expert panelists, who then sensorily evaluated the brightness of the made-up skin 8 hours after application according to the following criteria. The results were shown as the total score given by the five panelists. 5;Makeup makes the skin look brighter. 4;Makeup skin looks slightly brighter. 3;The skin with makeup doesn't look very bright. 2;Makeup does not look bright. 1; My makeup-covered skin doesn't look bright at all.

[0066] (4) Evenness of skin after 8 hours of application: Each foundation was applied to the skin by five expert panelists, who then sensorily evaluated the evenness of the makeup on the skin 8 hours after application, according to the following criteria. The results were expressed as the total score given by the five panelists. 5; Makeup skin looks even. 4; The makeup skin looks somewhat uniform. 3;The makeup doesn't look very even. 2;The makeup doesn't look even. 1;The makeup doesn't look even at all.
