Description

  The present invention relates to a lip cosmetic.

  Conventionally, various studies have been made to increase the durability of the makeup effect of lip cosmetics. Among them, a wide range of methods have been widely adopted in which volatile oils such as volatile silicones and volatile hydrocarbon oils are blended with resins such as silicone resins, and the cosmetic effect is sustained by a resin film formed after volatilization of the volatile oil. ing. However, with this method, it is difficult to avoid the dryness of the lips caused by volatile oil, the loss of glossiness of the makeup film, and the uncomfortable feeling of the lips caused by the resin film. Is not done.

  Patent Documents 1 and 2 propose oil-based cosmetics that improve the sustainability of the cosmetic effect while avoiding the drawbacks of the volatile type color-continuation lipstick as described above by using a specific modified polysiloxane. .

Japanese Patent No. 3477222 Japanese Patent No. 4584697

  However, although the use of these specific modified polysiloxanes has improved the durability of the cosmetic effect, the color transfer resistance to the cup and the glossiness of the cosmetic coating film have not reached a sufficiently satisfactory level.

  Accordingly, an object of the present invention is to provide a lip cosmetic that is excellent in color transfer resistance, durability of a makeup effect, glossiness of a cosmetic coating film, and good stability.

  Therefore, the present inventors have studied to improve the color transfer resistance, the durability of the makeup effect, the glossiness and stability of the cosmetic coating film, and as a result, phenyl that has been used to impart a glossy feeling to conventional cosmetic films.

  INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a lip cosmetic that is excellent in color transfer resistance, durability of a makeup effect, and glossiness of a cosmetic coating film, and also has good stability.

  Hereinafter, the present invention will be described in detail.

In the lip cosmetic of the present invention, the components (A) to (D) are stably held in the gaps in the wax structure of the component (E). At this time, the component (A) is the component (B). It exists in the state separated from (D).
Usually, component (A) phenyl-modified silicone is often incompatible with ester oils and hydrocarbon oils blended in lip cosmetics, and when component (A) is mixed with an incompatible oil agent It is separated and cannot be made into a preparation.
On the other hand, in a prescription system in which component (A) is completely compatible with other oil agents, although high gloss derived from component (A) can be realized, color transfer resistance is not exhibited, and the cosmetic effect is sustained. Regarding sex, it is not a satisfactory level.
However, in the present invention, the oil phase containing the components (A) to (E) is uniformly dissolved during the heating production, and after cooling, the component (A) is separated from the components (B) to (D). However, since any component is held in the gap in the wax structure of component (E), it is stable as a preparation. When the lip cosmetic of the present invention in such a state is applied, the particles of the component (A) held in the wax structure are coalesced to be separated from the oil phase and exposed to the coating surface. A cosmetic coating film with high glossiness and high color transfer resistance is realized.

The component (A) phenyl-modified silicone used in the present invention may be a silicone having a dimethylsiloxane skeleton and at least a part of the methyl group substituted with a phenyl group.
