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, it applies lipstick to a lipstick overcoat to form a film excellent in water and oil repellency, thereby improving the cosmetic effect of lipstick. The present invention relates to a lipstick overcoat which improves durability, suppresses adhesion to tableware, etc., and has a good dispersed state without aggregates.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
The lipstick overcoat is provided as a product for the purpose of maintaining the cosmetic effect of lipstick and improving the gloss. These lipstick overcoats contain a polymer compound such as a cellulose-based polymer compound, a vinyl-based resin, or an acrylic resin, a silicone oil, or the like in an aqueous or alcohol-based composition.
It is one that utilizes the characteristics of the polymer compound to be blended, or one that is a powder or a press that has a powder mixed with oil as the main component (Japanese Patent Publication No. 61-12883).
JP-A-61-24512).

However, conventional lipstick overcoats have not been sufficiently satisfactory to prevent the lipstick from adhering to dishes (color shift). In addition, powdery ones have poor usability, and the effect is uneven depending on the coating method, and those of a type in which a polymer compound or the like is blended have a sticky feeling in use and have a problem in sensory characteristics. there were. For this reason, the durability of the lipstick makeup effect is improved,
There has been a demand for a lipstick overcoat which can suppress color transfer of lipstick and is excellent in usability.

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)
No. 246,211, Japanese Patent Application Laid-Open No. 3-246212, Japanese Patent Application Laid-Open No. 3-264511). 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 earlier ( Japanese Patent Application Laid-Open No. 5-221829).
No. ).

[0006] The lipstick overcoat having the above-mentioned constitution is a highly effective technique which has never been obtained before, and is a useful technique. However, further investigation revealed that, depending on the type of powder, the blending amount of each component, and the like, agglomerates of powder are formed. It was revealed that there is a case where the dispersion state is not good, and there is a need for improvement.

[0007]

In [Means for Solving the Problems] Such circumstances, the present inventors have as a result of intense research, when blended powder treated with a specific fluorine compound a fluorine-based oil agent specific,
It has been found that a lipstick overcoat having improved durability of the makeup effect of lipstick, suppressing adhesion of lipstick to tableware and the like and color bleeding, and being easily usable and having excellent dispersibility can be obtained. Came to complete.

That is, the present invention provides the following components (A) and (B) (A) the following general formula (1);

(Evaluation method) Color transfer prevention effect: Lipstick was applied to a human upper arm with lipstick at a length of 3 cm.
After applying it twice and applying a lipstick overcoat on it,
The glass plate was pressed and the color shift was observed. A sample having excellent effect was evaluated as ⊚, a sample having almost effect was evaluated as ◯, a sample having little effect was evaluated as Δ, and a sample having no effect was evaluated as x.

Oil repellency: 8m doctor blade on glass plate
A coating film of a lipstick overcoat was prepared with an il, squalane was dropped on the coating film, and the state of the coating film was observed 1 hour later, and the oil repellency was evaluated by the degree of repulsion of the squalane. A sample having excellent effect was evaluated as ⊚, a sample having almost effect was evaluated as ◯, a sample having little effect was evaluated as Δ, and a sample having no effect was evaluated as x.

Dispersibility: 8m doctor blade on glass plate
A coating film of the lipstick overcoat was prepared with an il and the state of the coating film (aggregate) was observed. ◎ with no aggregates,
A sample having a little aggregate was evaluated as ◯, a sample having an aggregate was evaluated as Δ, and a sample having a large amount of aggregate was evaluated as x.

Persistence of cosmetic effect: The panel was made to have a normal life, lipstick was applied to the lips, and half of them had samples (1) to (5), and the other half had samples (6). ) ~
After applying (10), the makeup retention after half a day was compared on the left and right. A sample having excellent effect was evaluated as ⊚, a sample having almost effect was evaluated as ◯, a sample having little effect was evaluated as Δ, and a sample having no effect was evaluated as x.
