Description

  The present invention relates to an oily eye makeup cosmetic that is excellent in slipping property during application, that dries quickly after application, and that is extremely excellent in finish and makeup lasting.

  Conventionally, eye shadows that have a high lasting effect and are less likely to transfer color are formulated with volatile silicone in combination with wax or non-volatile oil, or by increasing the amount of pigment to leave the pigment on the eyelid surface. It was. Furthermore, a silicone resin was added to form a film on the surface of the eyelid after the volatile silicone volatilized, thereby further enhancing the difficulty of dropping (see Patent Document 1). However, since volatile silicone and light isoparaffin are less volatile in the conventional technology, it takes a long time for the volatile oil to volatilize, and when volatile silicone or light isoparaffin is used as the volatile oil, Increasing the compounding amount of the resin has the drawback that the slipping property at the time of coating is poor and color unevenness occurs at the time of coating.

  In addition, cosmetics that are hydrophobic ether and a fluorine-based oil and are strong against sebum and have a smooth use feeling have been reported (see Patent Document 2). However, eye shadows used in eyelids have physical properties such as blinking. The movement of the eye shadow was so intense that the applied eye shadow was lost, which was not preferable. Moreover, although there exist some which improved the durability by mix | blending hydrofluoroether and a fluorine wax (refer patent document 3), the makeup | decoration of an eye shadow produced too and was not preferable.

Japanese Patent Laid-Open No. 9-175990 Japanese Patent No. 3211740 Japanese Patent Laid-Open No. 11-322529

  Under such circumstances, an object of the present invention is to provide an oily eye makeup cosmetic that is excellent in slipping property at the time of application, that dries quickly after application, and that is extremely excellent in finish and makeup.

The present invention that achieves the above object comprises the following components (A), (B), (C) and (D):
(A) General formula (1):
_{C n F 2n + 1 -O-} C x H2 x + 1 (1)
[In formula, n is 1-6, x is 1-6. ]
10-60 mass% of hydrofluoroether represented by
(B) Silicone resin 3 to 30% by mass
(C) 10-50 mass% of pigment
(D) An oily eye makeup cosmetic containing an organically modified clay mineral as an essential component.

According to the present invention, characteristics of use (smoothness and goodness), speed of drying (speed of film formation),
It is possible to provide an oily eye makeup cosmetic that is extremely excellent in sustainability over time (good makeup) and in difficulty of transfer (no adhesion to tissue paper when lightly rubbed with tissue paper).

  Hereinafter, the present invention will be described in detail.

The hydrofluoroether used in the present invention has the general formula (1):
_{C n F 2n + 1 -O-} C x H2 x + 1 (1)
[In formula, n is 1-6, x is 1-6. ]
Specifically, C ₄ F ₉ OCH ₃ , C ₄ F ₉ OC ₂ H ₅ , C ₅ F ₁₁ OC ₂ H ₅ , C ₃ F ₇ OC ₄ H ₉ , C ₄ F ₉ OC ₄ H ₉ and the like, methyl perfluorobutyl ether sold under the name “Cosmetic Fluid CF-61” from 3M and ethyl perfluoro marketed under the name “Cosmetic Fluid CF-76” Examples include butyl ether. These hydrofluoroethers may be used alone or in combination of two or more. The compounding quantity of hydrofluoroether is 10-60 mass% with respect to cosmetics whole quantity, Preferably it is 15-50 mass%, More preferably, it is 20-40 mass%. If it is less than 10% by mass, no superiority is observed in the drying speed. If it exceeds 60% by mass, separation of the liquid oil or aggregation of the pigment occurs, which is not preferable for storage stability.

  Examples of the silicone resin used in the present invention include methyl silicone, a highly polymerized methyl phenyl silicone, trimethylsiloxysilicic acid, and examples of the modified silicone resin include acrylic silicone and fluorine-modified silicone, and the modified portion is blocked. It may be bonded to the state or may be bonded to a graft state or a pendant state, and all resins having a polysiloxane structure in the polymer and capable of forming a film are included. Among these, perfluoroalkyldimethyl-trimethylsiloxysilicic acid or trimethylsiloxysilicic acid is preferably used as the silicone resin from the viewpoint of film formability and film toughness. The compounding quantity of a silicone type resin is 3-30 mass% with respect to cosmetics whole quantity, Preferably it is 5-20 mass%, More preferably, it is 8-15 mass%. If it is less than 3% by mass, no superiority is seen in the lasting effect, and if it exceeds 30% by mass, the smoothness during coating decreases, which is not preferable.

  The pigment used in the present invention may be any pigment as long as it is used in eye makeup cosmetics, such as tar dyes, natural dyes, bengara, yellow iron oxide, black iron oxide, gunjo, conger, titanium oxide, manganese violet, oxidation Color pigments such as chrome and pearls, talc, mica, kaolin, magnesium carbonate, calcium carbonate, nylon powder, resin beads, silica powder, silk powder, nylon powder, silicone powder for the purpose of adjusting the feel and texture Pigments and pigments that can be incorporated into eye makeup cosmetics, such as extender pigments such as urethane powder, laminating agents such as polyethylene terephthalate methyl methacrylate laminated powder, silver or titanium oxide coated on glass flakes, lame-like glossy pigments, etc. All included. These pigments may be coated with silicone, lauroyl lysine, stearoyl glutamate, perfluoroalkyl phosphoric acid, polyethylene or other oil agents on the surface. The blending amount of the pigment used in the present invention is 10 to 50% by mass with respect to the total amount of the cosmetic, and is increased or decreased within this range according to the desired color tone. If it is less than 10% by mass, a cosmetic effect as an eye makeup cosmetic cannot be obtained, and if it exceeds 50% by mass, the smoothness during application decreases, which is not preferable.

The organically modified clay mineral used in the present invention is obtained by treating a water-swellable clay mineral such as bentonite, magnesium aluminum silicate, laponite, hectorite with a quaternary ammonium salt type cationic surfactant. It is. The quaternary ammonium salt type cationic surfactant used here is represented by the following general formula (2).
