Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is based on 100 parts by weight of powders, and contains 12 to 6 methylhydrogenpolysiloxanes.
Makeup cosmetics containing 0 parts by weight and modified powder obtained by heat treatment at 70 to 200 ° C. for 0.5 to 24 hours, and modified powder coated with a fluorine-containing compound. The purpose is to provide. More specifically, it is an object of the present invention to provide a makeup cosmetic that is resistant to collapse and has excellent durability and feel.

2. Description of the Related Art Conventionally, the problems to be solved by the invention
When a modified powder coated with a fluorine-containing compound (hereinafter referred to as a fluorine-treated powder) is mixed in a makeup cosmetic, it is necessary to use an oil agent having high viscosity or a fluorine-based 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 used in makeup cosmetics in the past, is repelled, and it functions as a binder that holds the powder together. Is weakened.

Therefore, a fluorinated oil agent having a low surface tension such as perfluoropolyether has come to be used. The fluorinated oil certainly wets the fluorinated powder, but due to its low surface tension, it did not function sufficiently as a binder. Therefore, there is a problem that the cosmetics are likely to collapse.

On the other hand, a highly viscous oil agent such as 35
Although dimethylpolysiloxane of 0 cs or more wets the fluorine-treated pigment and has a sufficient function as a binder, it has a problem that it is difficult to mix it with makeup cosmetics because of its high viscosity. Particularly in the case of manufacturing a powder foundation, when the binder is mixed using a device having a weak stirring force such as a Henschel mixer, there is a problem that the binder is not uniformly mixed and localized.

Further, as disclosed in Japanese Patent Application Laid-Open No. 62-267213, the method of coating the surface of the pigment with highly viscous silicone oil in advance is effective for the problems of the above-mentioned manufacturing method, but it is obtained. The cosmetics used tend to have a heavy feel, and there is a problem that the degree of freedom in prescription is significantly limited.

On the other hand, the present inventor has found that 100 parts by weight of the powders are mixed with 1 part of methyl hydrogen polysiloxane.
2 to 60 parts by weight, and 0.5 to 70 at 200 to 200 ° C
The modified powder obtained by heating for 24 hours (hereinafter referred to as "heavy coat-treated powder") has a resin film with high viscosity formed on the surface of the powder. It was found that even when designed, it is possible to obtain a cosmetic that is hard to collapse and has excellent durability, but there is a problem that it has a feeling different from that of conventional cosmetics.

Therefore, the present inventor has conducted diligent research in view of these problems. As a result, by mixing the modified powder and the fluorine-treated powder at the same time, the problem of the cosmetic composition containing the fluorine-treated powder collapsed. At the same time as solving the easiness, we succeeded in obtaining a feeling close to that of conventional cosmetics.

This is because the heavy coat-treated powder plays a role of a binder for holding the fluorine-treated powder together, and the strong bonding force between the heavy-coated powders is weakened by the fluorinated powder. it is conceivable that.

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

[0010]

The present invention is directed to powders 100
12 to 60 parts by weight of methyl hydrogen polysiloxane is coated on a part by weight basis, and 0.5 to 0.5 at 70 to 200 ° C.
The present invention relates to a makeup powder containing a modified powder obtained by heating for 24 hours and a modified powder coated with a fluorine-containing compound.

The structure of the present invention will be described in detail below. Examples of powders used in the present invention include lake pigments such as yellow No. 203 Ba lake, nylon powder, silk powder, urethane powder, Teflon powder, silicone powder, cellulose powder and other polymers, yellow iron oxide,
Colored pigments such as red iron oxide, black iron oxide, chromium oxide, cobalt oxide, carbon black, ultramarine, and navy blue, zinc oxide,
White pigments such as titanium oxide and cerium oxide, body pigments such as talc, mica, sericite and kaolin, pearl pigments such as titanium mica, barium sulfate, metal salts such as calcium carbonate, magnesium carbonate, aluminum silicate and magnesium silicate, N -Organic substance-coated pigments such as acyl aspartic acid-coated mica, metal soap treated pigments, zeolite, silica,
Examples thereof include inorganic powders such as alumina, fine particle titanium oxide, fine particle zinc oxide, fine particle black iron oxide, alumina-treated fine particle titanium oxide, silica-treated fine particle titanium oxide, wool, and N-lauroyl-L-lysine.

The methylhydrogenpolysiloxane used in the present invention may be either linear or cyclic, but S in the molecule.
It is necessary to have at least one i-H group. 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 0.3 to 1, and more preferably 0.5 to 1.

In the present invention, in order to control the polymerizability of methylhydrogenpolysiloxane, methylhydrogenpolysiloxane having two or more kinds of structures can be used in combination. For example, the introduction of methylhydrogenpolysiloxane having a dimethylsiloxane unit is characterized in that the powder feels soft.

In the present invention, oil agents, silicone oils, fluorine-based oil agents, resins, silane coupling agents, titanium coupling agents, alkoxysilanes, alkoxytitanium, trimethyl, which have been used in cosmetics together with methylhydrogenpolysiloxane. Siloxysilicic acid or the like may be simultaneously coated. Examples of silicone oils include those having a siloxane skeleton such as dimethylpolysiloxane, methylphenylpolysiloxane, polyether-modified silicone, alkyl-modified silicone, one-end reactive silicones and both-end reactive silicones. These substances are effective as touch modifiers because they change the feel characteristics of the polymer film of methylhydrogenpolysiloxane, but care must be taken because they often cause film polymerization inhibition. In particular, since the film may redissolve over a period of about one year, when these substances are used, daily observation at room temperature and 40 ° C. is essential.

In the present invention, the ratio of the powders coated with methylhydrogenpolysiloxane is 12 to 60 parts by weight based on 100 parts by weight of the powders. If it is less than 12 parts by weight, the effect of the present invention tends to be weakened, and if it exceeds 60 parts by weight, a polymer lump composed of powder and resin tends to be formed, which is not preferable.

In the present invention, the method for coating the powders with methylhydrogenpolysiloxane is a dry method in which the two are mixed using a Henschel mixer, a super mixer or the like, or a powder in a solvent such as water or hexane. After dispersing the body, there is a wet method of mixing methylhydrogenpolysiloxane and removing the solvent, a method of using a mechanochemical type mill such as a ball mill or an ong mill, a method of using a spray dryer, etc. The cheapest dry method is preferred.

The heating condition used in the present invention is a heating temperature of 70.
˜200 ° C., heating time 0.5 to 24 hours. The heating conditions do not have to be constant, and for example, a method of performing a heat treatment at 90 ° C. for 1 hour, returning the temperature to room temperature, and further performing a heat treatment at 180 ° C. for 6 hours is also possible. If the temperature is lower than 70 ° C, the polymerization of methylhydrogenpolysiloxane is difficult to proceed,
On the other hand, when the temperature exceeds 200 ° C., a reaction such as conversion of methylhydrogenpolysiloxane into silica occurs, which causes a problem of deterioration in quality. The heating time is 0.5
If it is less than time, the reaction is difficult to proceed sufficiently, and if it exceeds 24 hours, it becomes economically disadvantageous.

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

The fluorinated powder used in the present compound may be a powder obtained by coating the above powders with a compound having a fluorine atom introduced therein. For example, perfluoroalkyl phosphoric acid ester salts described in US Pat. No. 3,632,744, perfluoroalkylsilanes, perfluoropolyethers, perfluoroalcohols, fluorocarbons, Teflon, perfluorocarboxylic acids and perfluorosulfuric acid. Examples of the powder include a powder coated with a compound such as a salt. The fluorine-treated powder is coated with 0.5 to 50 parts by weight.

As the mother powder to be treated with fluorine,
For example, the above-mentioned powders are also mentioned.

Further, the heavy coat-treated powder and the fluorine-treated powder used in the present invention are resins such as acrylic, oil agents, silicone oils, fluorine-based oil agents, surfactants, amino acids, etc. which have been used in conventional cosmetics. The coating process may or may not be performed.

In the present invention, the blending 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, relative to 100 parts by weight of the cosmetic. It is a department.

In the present invention, in addition to the above-mentioned modified powder, powders, resins, oils, silicone oils, surfactants, ultraviolet absorbers, fragrances, preservatives, bactericides, etc. which are usually used in cosmetics, A solvent, water, etc. can be added at the same time.

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