Abstract

The object of the present invention is to provide a cosmetic set that does not bleed, does not cause stains on tableware, etc. during use, has an excellent anti-stain effect, does not feel tight after use, and does not fade over time. The cosmetic kit of the present invention that solves this problem is characterized in that it includes a first composition and a second composition, the first composition is applied to the application part, and then the second composition is applied thereon, and the first composition The product and the second composition respectively contain the following components, (the first composition) (A) a film-forming silicone resin (B) a silicone oil having a kinematic viscosity at 25°C of 1,000 to 1,000,000 cs (C) a volatile When the hydrocarbon oil (D) coloring pigment (second composition) is mixed with the mixture obtained by mixing the aforementioned component (A) and the aforementioned component (C) at a mass ratio of 1:1, and left to stand at 25°C for 60 minutes The oil agent of the component (E) which phase-separated.

Description

technical field [0001] The present invention relates to a cosmetic set comprising a first composition and a second composition, and relates to a cosmetic set in which the first composition is applied to an application site and then the second composition is applied thereon. Background technique [0002] In recent years, makeup cosmetics such as lipsticks and foundations have become problems with time-lapse makeup and staining on containers, clothes, and the like. In particular, with regard to lipstick, various researches have been conducted on the problem that the lipstick applied on the lips is stained on tableware such as coffee cups, and that the makeup fades over time due to the physical friction of the lips, etc. . [0003] For example, as a technique for imparting an anti-staining effect and an anti-makeup effect, it has been proposed to apply polyisobutylene having a relative mass of 3,000 to 1,000,000 and a volatile hydrocarbon oil to a first composition containing ...
