Description

TECHNICAL FIELD The present invention relates to a stick-shaped cosmetic, and more particularly to a stick-shaped cosmetic comprising an outer layer and an inner core.

2. Description of the Related Art Among stick cosmetics such as lipsticks, there are known cosmetics composed of multiple phases having different compositions. A representative example is a lip cosmetic comprising a substantially cylindrical inner core and an outer layer having a shape covering the side surface thereof. For example, Patent Literatures 1 and 2 describe stick-like cosmetics in which the inner core is an aqueous cosmetic and the outer layer is an oily cosmetic.

Further, Patent Document 3 describes a multi-phase molded cosmetic in which a transparent phase is arranged in the inner core and an opaque phase is arranged in the outer layer so as to be in contact, for example, the transparent phase is lip gloss and the opaque phase is lipstick. describes a multi-phase molded cosmetic that can be applied to the lips and rubbed the upper and lower lips to make glossy lips.

Further, in Patent Document 4, for the purpose of good storage stability against temperature changes, a gel-like stick such as a soft gel or a hard gel or a molded gel is used as an outer layer, and the temperature is less than the melting point of the composition constituting the outer layer. A dual function product is described which consists of an inner core with a melting point. Patent Document 5 discloses a cosmetic that combines a lipstick, a lip gloss and a lip liner, with the lip gloss as a core and a lip liner extending along a longitudinal axis on the outer periphery.

Multiphase molded cosmetics such as those described above are made by giving each phase a plurality of properties that are difficult to achieve in a single composition (single phase), and by joining them together, it is possible to achieve both properties. , one phase can compensate for the shortcomings of the other phase to achieve the desired properties.
