Hereinafter, the present invention will be described in detail. The major difference between the lipstick composition of the present invention and the above-mentioned JP-B-61-12884 is that the publication discloses, as an organic medium, lower alcohols such as ethanol, propanol and isopropanol or mineral spirits and isopanol. -(Esso Oil Co., Ltd.), IP solvent (Idemitsu Oil Co., Ltd.) and other aliphatic hydrocarbons, aromatic hydrocarbons or mixtures thereof are used, whereas in the present invention, the above-mentioned medium (outer phase) is used as the medium (outer phase). The use of volatile silicones having better characteristics in odor and skin safety than the medium is used.

Japanese Patent Publication No. 61-12884 discloses that
Among makeup cosmetics, the present invention particularly relates to an eyeliner, a mascara, an eyebrow, and a manicure, and Examples other than these are not disclosed. On the other hand, the present invention relates to makeup cosmetics, particularly to a lipstick composition.

Can be produced by polymerizing a polymerizable monomer. Although any polymerizable monomer can be used here, in particular,
A radical polymerizable monomer is preferable, and it can be produced by radical polymerization of the monomer in a volatile silicone solvent using a radical initiator. It is also possible to produce a polymer polymerized by any method such as anionic polymerization, cationic polymerization, and radical polymerization by stably dispersing the polymer in a volatile silicone. Preferred in terms of surface. The composition ratio of the polymer and the volatile silicone in the non-aqueous polymer dispersion is arbitrary, but is preferably in the range of (polymer) :( volatile silicone) = 1: 25 to 6: 1, and more preferably.

The medium is not particularly limited as long as it is a volatile silicone, but volatile silicones represented by the above-mentioned general formulas “Chemical formula 9” and “Chemical formula 10” are preferable.

The amount of the non-aqueous polymer dispersion is preferably in the range of 10 to 80% by weight, more preferably 20 to 50% by weight, based on the total weight of the lipstick composition. If the amount is less than 10% by weight, color transfer to coffee cups and clothes occurs, resulting in poor makeup. On the other hand, if the amount is more than 80% by weight, the easiness of coating becomes poor, which is not preferable.

The fluorine-modified silicone or fluorine-modified methylphenylpolysiloxane contained in the lipstick composition of the present invention is one or more of the above-mentioned general formulas (6) and (8). The amount thereof is preferably in the range of 5 to 40% by weight, more preferably 10 to 30% by weight, based on the total amount of the lipstick composition.

If the content is more than 0% by weight, the film-forming ability of the non-aqueous polymer dispersion using the volatile silicone of the present invention as a medium is impaired, and the makeup after eating becomes poor, which is not preferable.

The lipstick composition of the present invention spreads smoothly when applied to the lips, is easy to apply, has no stickiness, has good luster on the lips, and transfers color to coffee cups, clothes and the like. In addition to the above-mentioned essential ingredients for obtaining the unique effect of being excellent in makeup after meals in particular, if necessary,
