Description

The present invention relates to lip cosmetics.

Lipstick cosmetics have conventionally been required to have various finishes, and various products have been developed in accordance with the desired finishes.
For example, in Patent Document 1, trimethylpentaphenyltrisiloxane, a liquid oil component at 25° C., a silicone having a nonionic hydrophilic group, and a wax solid at 25° C. are included as a method for achieving a smooth finish after coating. The oily cosmetics which do are described.
Further, as a method of having sufficient gloss and shine after application and maintaining the gloss, Patent Document 2 discloses an oil-in-water emulsion containing a non-volatile hydrocarbon oil, methylphenyl silicone, an aqueous component and a coloring material. A cosmetic for emulsified lips is described, and Patent Document 3 makes up skin and/or lips containing a non-volatile hydrocarbon non-polar oil, a non-volatile non-phenylated silicone, and a non-volatile phenylated silicone oil. A cosmetic composition for doing is described.
On the other hand, recently, lipsticks with a matte finish are also preferred in addition to lipsticks with such a glossy finish. In order to obtain a matte-finished lipstick, for example, the amount of powder containing a pigment is increased or a large amount of volatile oil is added.
