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 particularly, to a lipstick which improves the persistence of the lipstick's cosmetic effect by being applied on a lipstick and suppresses adhesion to dishes and the like. Regarding overcoat.

[0002]

2. Description of the Related Art
The lipstick overcoat is provided as a product for the purpose of maintaining the cosmetic effect of the lipstick, improving gloss, and the like. These lipstick overcoats are blended with a water-based or alcohol-based polymer compound such as a cellulose polymer compound, a vinyl resin, an acrylic resin, or a silicone oil.
It was a compound utilizing characteristics such as a polymer compound to be compounded, or a powder or a press containing a powder mixed with an oil as a main component (Japanese Patent Publication No. 61-12883,
JP-A-61-24512).

[0003] However, the conventional lipstick overcoat has not been sufficiently satisfactory to prevent the lipstick from adhering to tableware and the like (color change). In addition, powdery materials have poor usability, and the effect is uneven depending on the method of application, and those containing a high molecular compound etc. have a sticky feeling in use, and also have a problem in the sense of function. there were.

[0004] For this reason, there has been a demand for a lipstick overcoat which can improve the persistence of the cosmetic effect of the lipstick, suppress the color change of the lipstick, and have excellent usability.

On the other hand, perfluoropolyether is a fluorine-based liquid oil excellent in water repellency and oil repellency, and cosmetics utilizing this are known (JP-A-63-107).
911, JP-A-3-246221, JP-A-3-246212, JP-A-3-264511, etc.). However, no attempt has been made to apply this to a lipstick overcoat.

[0006]

Under such circumstances, the present inventors have conducted intensive studies and as a result, it has been found that the addition of a specific amount of a specific powder to perfluoropolyether can improve the persistence of the cosmetic effect of lipstick. The present inventors have found that a lipstick overcoat that can suppress lipstick adhesion to tableware and the like and color bleeding and that can be used easily can be obtained, and thus completed the present invention.

That is, the present invention provides the following components (a) and (b) (a)

Wherein R ¹ , R ² , R ³ , R ⁴ and R ⁵ are the same or different and each represents a fluorine atom, a perfluoroalkyl group or an oxyperfluoroalkyl group;
p, q and r are 0 giving a molecular weight of 500 to 10,000
The following integers are shown. (However, p = q = r = 0 is not satisfied.) 75 to 99.8% by weight of perfluoropolyether represented by the formula (b): 0.2 to 25% by weight of silica powder and / or alumina powder. A lipstick overcoat is provided.

The perfluoropolyether of the component (a) used in the present invention is represented by the general formula (1), has water repellency and oil repellency, and has room temperature (about 25 ° C.).
Is a non-volatile liquid.

Of these, the viscosity is particularly 5 to 5,000.
A perfluoropolyether of cSt is preferable, for example, the following general formula (2)

(Wherein l is a number from 4 to 500), commercially available products such as Demnum S-20 and S
-65, S-100 and S-200 (manufactured by Daikin Industries, Ltd.).

These perfluoropolyethers are blended in an amount of 75 to 99.8% by weight, preferably 80 to 99% by weight, based on the total composition. If it is less than 75% by weight, the usability is not good, and if it exceeds 99.8% by weight, the amount of component (b) is too small, which is not preferred.

The silica powder and the alumina powder of the component (b) may be those used in ordinary cosmetics, for example, Syloid 55 (Fuji Devison Chemical Co., Ltd.)
Manufactured), Ezrol 200, 300, R-972, R-9
74 (manufactured by Fuji Chemical Co., Ltd.), alumina AKS-G, AK
P-30, AKP-GM (manufactured by Sumitomo Chemical Co., Ltd.) and the like can be suitably used.

These silica powder and alumina powder are:
They can be used alone or in combination of two or more, and 0.2 to 25% by weight, preferably 1 to 20% by weight in the total composition
Be blended. If the amount is less than 0.2% by weight, a remarkable effect cannot be obtained, and if it exceeds 25% by weight, it becomes difficult to apply the coating.

Furthermore, in the present invention, in addition to the above essential components, components used in ordinary cosmetics, for example, cosmetic oils such as hydrocarbons, higher fatty acid esters, animal and vegetable oils and fats, silicones, surfactants, antioxidants , Fragrances, pigments,
Alcohol, polyhydric alcohol, preservative, ultraviolet absorber,
A humectant, water and the like can be appropriately compounded within a range that does not impair the effects of the present invention.

The lipstick overcoat of the present invention can be produced by adding the silica powder and / or the alumina powder of the component (b) to the perfluoropolyether of the component (a) and mixing them. Obtained as a form.

[0021]

According to the lipstick overcoat of the present invention, by applying the lipstick onto the lipstick, the makeup effect of the lipstick can be remarkably improved, and the lipstick can be prevented from adhering to dishes and the like. In addition, the effect is exhibited immediately after application, so that the lipstick becomes unclear over time, that is, so-called color bleeding can be suppressed, and since it is a paste, it can be used easily.
