2. Description of the Related Art
When blending a modified powder coated with a fluorine-containing compound (hereinafter referred to as a fluorinated powder) into a makeup cosmetic, it was necessary to use a highly viscous oil agent or a fluorine oil agent as a binder. This is because the surface of the fluorinated powder is often water- and oil-repellent, and the oil agent such as liquid paraffin, which has been conventionally used for makeup cosmetics, is repelled and serves as a binder to hold the powder together. Is weakened.

Therefore, fluorine-based oils having a low surface tension such as perfluoropolyether have been used. Although the fluorinated oils did wet the fluorinated powders, their function as a binder was not sufficient due to their low surface tension. For this reason, there has been a problem that the cosmetic is likely to collapse.

On the other hand, oils having high viscosity, for example, 35
Dimethylpolysiloxane of 0 cs or more wets the fluorinated pigment and also has a sufficient function as a binder, but has a problem that it is difficult to mix it into a makeup cosmetic because of its high viscosity. In particular, taking the production of a powder foundation as an example, when the binder is mixed using an apparatus having a low stirring power such as a Henschel mixer, there is a problem that the binder is not uniformly mixed and is localized.

As disclosed in Japanese Patent Application Laid-Open No. 62-267213, a method of coating a pigment surface with a highly viscous silicone oil in advance is effective for the problems of the above production method, The resulting cosmetics tend to have a heavy feel, and there is a problem that the degree of freedom of formulation is greatly limited.

On the other hand, the present inventor has proposed that methylhydrogenpolysiloxane 1 per 100 parts by weight of powders.
2 to 60 parts by weight, and at 70 to 200 ° C.
The modified powder obtained by heat treatment for 24 hours (hereinafter referred to as “heavy coat treated powder”) has a highly viscous resin film formed on the surface of the powder. Even when designed, it has been found that a cosmetic that is hard to crumble and has excellent durability can be obtained, but there is a problem that the cosmetic has a different feel from conventional cosmetics.

In view of these problems, the inventors of the present invention have conducted intensive studies, and found that by combining the modified powder and the fluorinated powder at the same time, the collapsing which was a problem of the fluorinated powder-containing cosmetic was obtained. At the same time as solving the simplicity, we succeeded in obtaining a feeling similar to conventional cosmetics.

This is because the heavy-coated powder acts as a binder for binding the fluorinated powder, and the strong bonding force between the heavy-coated powders is weakened by the fluorinated powder. it is conceivable that.

[0009] That is, an object of the present invention is to provide a makeup cosmetic which is resistant to collapse, has high durability, and is excellent in feel.

SUMMARY OF THE INVENTION The present invention relates to a method for manufacturing powders 100.
To 60 parts by weight of methyl hydrogen polysiloxane,
The present invention relates to a makeup powder containing a modified powder obtained by performing a heat treatment for up to 24 hours, and a modified powder coated with a fluorine-containing compound.

Hereinafter, the configuration of the present invention will be described in detail. Examples of powders used in the present invention include those conventionally used in cosmetics.
Powder, such as lake pigments such as Yellow No. 203 Ba lake, polymers such as nylon powder, silk powder, urethane powder, Teflon powder, silicone powder, and cellulose powder, yellow iron oxide, red iron oxide, and black. Colored pigments such as iron oxide, chromium oxide, cobalt oxide, carbon black, ultramarine and navy blue; white pigments such as zinc oxide, titanium oxide and cerium oxide; extender pigments such as talc, mica, sericite and kaolin; Pearl pigments, metal salts such as barium sulfate, calcium carbonate, magnesium carbonate, aluminum silicate, magnesium silicate, etc .; organic substance-coated pigments such as mica coated with N-acyl aspartic acid; metal soap-treated pigments; inorganic powders such as zeolite, silica and alumina , Fine particle titanium oxide, fine particle zinc oxide, fine particle black iron oxide, Mina processing fine particles of titanium dioxide,
Silica-treated fine particle titanium oxide, wool, N-lauroyl-
L-lysine and the like.

The methyl hydrogen polysiloxane used in the present invention may be linear or cyclic,
It is necessary to have one or more iH groups. Further, a dimethylsiloxane unit may be introduced in the molecule. The ratio of the number of Si-H groups to the number of Si atoms is preferably from 0.3 to 1, and more preferably from 0.5 to 1.

In the present invention, in order to control the polymerizability of methyl hydrogen polysiloxane, methyl hydrogen polysiloxane having two or more types of structures can be used in combination. For example, when a methylhydrogenpolysiloxane having a dimethylsiloxane unit is introduced, the touch of the powder is softened.

In the present invention, oil agents, silicone oils, fluorine oil agents, resins, silane coupling agents, titanium coupling agents, alkoxysilanes, alkoxytitanium, trimethyl Siloxysilicic acid or the like may be simultaneously coated. Examples of the silicone oils include those having a siloxane skeleton, such as dimethylpolysiloxane, methylphenylpolysiloxane, polyether-modified silicone, alkyl-modified silicone, one-terminal reactive silicones, and both-terminal reactive silicones. These substances are effective as a feel control agent because they change the feel characteristics of a polymer film of methylhydrogenpolysiloxane, but care must be taken because they often inhibit polymerization of the film. In particular, since the film may be redissolved in about one year, daily observation at room temperature and 40 ° C. is essential when using these substances.

In the present invention, the ratio of the powders coated with methyl hydrogen polysiloxane is 12 to 60 parts by weight based on 100 parts by weight of the powders. If the amount is less than 12 parts by weight, the effect of the present invention tends to be weakened. If the amount is more than 60 parts by weight, a polymerized lumps composed of a powder and a resin is formed, which is not preferable.

In the present invention, the powders may be coated with methylhydrogenpolysiloxane by a dry method in which the powders are mixed using a Henschel mixer or a super mixer, or a powder in a solvent such as water or hexane. After dispersing the body, there is a wet method of mixing methyl hydrogen polysiloxane and removing the solvent, a method using a mechanochemical type mill such as a ball mill, an ang mill, a method using a spray dryer, etc. The least expensive dry method is preferred.

The heating conditions used in the present invention are as follows.
~ 200 ° C, heating time 0.5 ~ 24 hours. The heating conditions may not be constant. For example, a method of performing heat treatment at 90 ° C. for 1 hour, returning to room temperature, and further performing heat treatment at 180 ° C. for 6 hours, or the like is also possible. If the temperature is lower than 70 ° C., the polymerization of methyl hydrogen polysiloxane hardly proceeds,
On the other hand, when the temperature exceeds 200 ° C., a reaction such as conversion of methyl hydrogen polysiloxane to silica occurs, which causes a problem of deterioration in quality. The heating time is 0.5
If the time is less than the time, the reaction does not proceed sufficiently, and if it is more than 24 hours, it is economically disadvantageous.

In the present invention, the amount of the modified powder coated with methyl hydrogen polysiloxane varies depending on the dosage form, but is preferably 0.1 to 95 parts by weight per 100 parts by weight of the cosmetic. , More preferably 1 to
80 parts by weight.

The fluorinated powder used in the present compound may be any powder that has been subjected to a coating treatment with a compound in which a fluorine atom has been introduced into the aforementioned powders. For example, perfluoroalkyl phosphoric acid ester salts described in U.S. Pat. No. 3,632,744, perfluoroalkylsilane, perfluoropolyether, perfluoroalcohol, fluorocarbon, teflon, perfluorocarboxylic acid and perfluorosulfuric acid Powders that have been coated with a compound such as a salt may be used. These fluorinated powders are coated with 0.5 to 50 parts by weight.

Further, as the mother powder to be fluorinated,
For example, the above-mentioned powders can be similarly mentioned.

Further, the heavy-coated powder and the fluorinated powder used in the present invention include resins such as acrylic resin, oils, silicone oils, fluorine-based oils, surfactants, amino acids and the like which have been conventionally used in cosmetics. It does not matter whether the coating process is performed or not.

In the present invention, the amount of the fluorinated powder varies depending on the dosage form, but is preferably 0.1 to 90 parts by weight, more preferably 0.5 to 35 parts by weight, per 100 parts by weight of the cosmetic. Department.

In the present invention, in addition to the above-mentioned modified powders, powders, resins, oils, silicone oils, surfactants, ultraviolet absorbers, fragrances, preservatives, antiseptic, A solvent, water and the like can be simultaneously added.

The powders may or may not have been subjected to surface treatment such as silicone treatment, silane treatment and fatty acid treatment. As oils, oils such as perfluoropolyether and fluorocarbon oil can be used in addition to alcohols, ester oils, hydrocarbon oils and the like. Examples of the silicone oil include dimethylpolysiloxane, methylphenylpolysiloxane, methylhydrogenpolysiloxane, polyether-modified silicone, fluoroalkyl / polyether co-modified silicone, perfluorosilicone, alkyl-modified silicone, and trimethylsiloxysilicic acid. . As the surfactant, a nonionic, cationic, or anionic surfactant can be used.
