Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lipstick overcoat, and more specifically, by applying the lipstick on the lipstick overcoat, the duration of the cosmetic effect of the lipstick is improved and the adhesion to tableware and the like is suppressed. Further, the present invention relates to a lipstick overcoat which is free from dust and gives a smooth and refreshing feel when used.

[0002]

2. Description of the Related Art Conventionally, a lipstick overcoat has been provided as a product for the purpose of maintaining the cosmetic effect of lipstick and improving the gloss. These lipstick overcoats are water-based or alcohol-based, cellulosic polymer compounds,
Compounds such as vinyl resin, acrylic resin, and other high-molecular compounds, silicone oil, etc. are used to make use of the characteristics of the high-molecular compound to be added, or powders or presses containing oil-mixed powder as the main component It was the one (Japanese Patent Publication Sho 61
-12883, JP-A 61-24512).

[0003]

However, the conventional lipstick overcoats have not been sufficiently satisfactory to prevent the lipstick from adhering (color transfer) to dishes or the like. In addition, powdery ones have poor usability, and the effect varies depending on the coating method.On the other hand, the ones containing a polymer compound have a sticky feeling in use and have a problem in sensory characteristics. there were. Therefore, it is possible to improve the durability of the makeup effect of the lipstick and suppress the color transfer of the lipstick,
Moreover, a lipstick overcoat having excellent usability has been desired.

On the other hand, the fluorinated oil agent is a liquid oil having excellent water repellency and oil repellency, and cosmetics to which this is applied are known. (JP-A-63-107911, JP-A-3)
-246211, Japanese Patent Laid-Open No. 3-246212, Japanese Patent Laid-Open No. 3-264511, etc.). However, no attempt has yet been made to apply this to a lipstick overcoat.

Under these circumstances, the applicant of the present invention improves the durability of the cosmetic effect of lipstick by mixing perfluoropolyether with a specific amount of silica powder and / or alumina powder, and the adhesion of lipstick to tableware and the like. We have found that a lipstick overcoat that suppresses color bleeding and that can be used easily is obtained, and filed a prior application ( JP-A-5-221829).
Gazette ).

[0006] The lipstick overcoat having the above-mentioned constitution is a technique which is more effective than ever before and is a useful technique. However, further studies have revealed that the lipstick overcoat is powdered over time depending on the type of powder and the blending amount of each component. It became clear that there was a case of snoring, and it was found that there is a need for improvement in terms of feel.

[0007]

Under such circumstances, the inventors of the present invention have conducted diligent research and, as a result, have found that a specific amount of a fluorinated oil agent is added to a specific amount of powder for cosmetics, an aqueous component and a specific water-soluble polymer. When blended with, the feel on use is smooth and refreshing, and by applying it over the lipstick it improves the duration of the makeup effect of the lipstick, and there is no dusting over time, and the lipstick adheres to tableware etc. Further, they have found that a lipstick overcoat that suppresses color bleeding and can be used easily is obtained, and has completed the present invention.

That is, the present invention provides the following component (A),
(B), (C) and (D) : (A) Fluorine-based oil agent 10 to 80% by weight (B) Cosmetic powder 0.2 to 20% by weight (C) Water and / or water-soluble alcohol 19. 79 to 89.79% by weight (D) Alkyl-modified carboxyvinyl polymer 0.01 to 2.0% by weight is provided.

The fluorine-based oil agent of the component (A) used in the present invention is a perfluoroorganic compound which is liquid at room temperature, and examples thereof include perfluoroalkane and perfluoropolyether represented by the general formula (1). To be

Ethanol, isopropyl alcohol, it is possible to have use of polyethylene glycol and the like. If the component (C) is not blended, the dusting of the component (B) will occur even if the effect of preventing color fringing remains over time. Therefore, by blending the component, the dusting of the powder can be suppressed, and the oily feel at the time of use. It is possible to reduce the size and give a refreshing feel.

In the present invention, the component (C) water and / or
The amount of the water-soluble alcohol blended is 19.79 to 89.79.
