Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lipstick composition which prevents the roughness of lips and has excellent stability over time.

[0002]

2. Description of the Related Art Conventionally, an organic pigment has been blended in a lipstick composition because it has a brighter color tone than an inorganic pigment, and an oil-soluble dye has been used for a long time in oily lipsticks. In particular, Fluorescein dye red No. 218 (tetrachlorotetrabromofluorescein), red 2
No. 23 (tetrabromofluorescein), orange 201 (dibromofluorescein) and the like are widely used. However, while these dyes have vivid coloration, they are dyed to skin proteins due to the opening of the lactone ring during application, which causes rough skin on the lips, and during storage,
There is a problem with stability over time, such that these dyes develop color and the appearance of the lipstick itself changes color.

As a means for reducing the dyeing property of fluorescein dyes to skin proteins, a method of incorporating a clay mineral has been studied for a long time, but in that case, the transparency and gloss of the coating film are not sufficient and satisfactory. I couldn't get anything. Also, as a technique for preventing discoloration of the appearance of lipstick, there is JP-A No. 1-175920, but there is a limit to the powders that can be blended, and there is no effect on rough lips. There was a drawback.

[0004]

As a method of remedying the above-mentioned drawbacks, it is conceivable to coat the surface of a fluorescein dye with an oil agent such as silicone oil. In this case, the treatment agent is used as a product during the manufacturing process and during storage. The dye dissolved in the base material was in a free state, and it was not possible to prevent roughness of the lips and maintain the stability of appearance color with time. Therefore, it is an object of the present invention to provide a lipstick composition which prevents lips from becoming rough and has excellent stability over time without discoloration of the appearance of the lipstick itself.

[0005]

In SUMMARY OF THE INVENTION such circumstances, the present inventors have result of intensive studies, fluorescein dyes and path
It was found that by blending -fluoropolyether with a lipstick composition into a lipstick composition, a lipstick composition having excellent stability over time, such as preventing lip roughness and preventing discoloration of the appearance of the lipstick itself, can be obtained. Completed the invention. That is, the present invention provides the following general formula (1):

No. etc. can be used.

The amount of the fluorescein-based dye used in the present invention is preferably 0.01 to 5% by weight, more preferably 0.05 to 1% by weight, based on the total amount of the lipstick composition. Further, the perfluoropolyether represented by the general formula (2) is 0.01 to 10 times in weight ratio with respect to the dye.
It is preferably 0.05 to 3 times. If it is less than 0.01 times, the dye will be dyed to the lips and there is a problem with stability over time, and the effect of the present invention cannot be sufficiently obtained. Also has no change in effect, 1
The effect is sufficiently obtained with 0 times.

One of the fluorescein dyes of the present invention
Pa is expressed by general formula (2) - Furuoroporie - but are not particularly limited how blending ether, represented by the fluorescein dye and the general formula (2) Pa - Furuoroporie - Te
If the lipstick composition is prepared by pre-mixing the ingredients with each other, a more excellent effect can be obtained. Regarding the mixing method, kneading with a three-roll mill, dry mixing with a Henschel mixer,
Alternatively, a wet treatment in which a fluorine-based oil agent is uniformly dissolved in a solvent, the dye is added and mixed, and then the solvent is distilled off may be used.

Further, in the present invention, in addition to the above-mentioned essential components, components generally used in cosmetics, for example, oil components such as silicone oil, waxes, pigments, preservatives, antioxidants, ultraviolet absorbers, humectants, agents , A fragrance, etc. can be appropriately blended within a range not impairing the effects of the present invention.
