Description

TECHNICAL FIELD The present invention relates to cosmetics, and more specifically, to cosmetics such as pigments due to sweat or sebum, which have excellent water repellency and water resistance, and also have oil resistance. The present invention relates to a cosmetic composition which prevents loss of components and has high makeup durability.

[Problems to be Solved by Prior Art and Invention]

Heretofore, many water- and oil-repellent powders obtained by treating powders with a fluorine compound have been known (JP-A-55-167209, JP-A-62-25).
0074, JP-A-1-180811, US Pat. No. 3,632,744, etc.).

On the other hand, cosmetics, especially make-up cosmetics, are required to have excellent water repellency and makeup durability. However, even if it is attempted to add powder surface-treated with a fluorine compound for the purpose of improving water repellency to an oil agent usually used in these cosmetics, the powder is not uniformly dispersed in the oil agent, resulting in water repellency, etc. It was difficult to obtain excellent cosmetics.

Therefore, the powder is evenly dispersed, excellent in water repellency and water resistance,
Moreover, cosmetics with high makeup durability have been desired.

[Means for Solving the Problems]

Under such circumstances, the inventors of the present invention have conducted diligent research and as a result, by using a powder treated with a fluorine compound and a fluorine-based oil agent in combination, the powder is uniformly dispersed in the oil agent, and a cosmetic such as a pigment by sebum is applied. The present invention has been completed by finding out that a cosmetic having an effect of preventing the disappearance of the components and a makeup lasting property can be obtained.

That is, the present invention provides a cosmetic characterized by containing components (A) and (B) (A) fluorine compound-treated powder 5 to 95% by weight (B) fluorine-based oil agent 5 to 95% by weight. To do.

The fluorine compound-treated powder of the component (A) used in the present invention means, for example, a powder represented by the general formula (I) [CmF ₂ m ₊₁ CnH ₂ nO] lPO (OH) _3- l (I) (wherein , M is an integer of 1 to 20, n is an integer of 1 to 5, and 1 is 1 or 2) or a salt thereof (for example, an alkali). Metal, ammonium or substituted ammonium), fluoroalkyldi (oxyethyl) amine phosphate ester (JP-A-62-250)
No. 074); resin having a perfluoroalkyl group (JP-A-55-167209), tetrafluoroethylene resin, perfluoroalcohol, perfluoroepoxy compound, sulfamide type fluorophosphoric acid, perfluorosulfate, perfluorocarboxylic acid. It is treated with a fluorine compound such as acid salt and perfluoroalkylsilane (a silane coupling agent such as LP-1T, LP-4T, LP-8T manufactured by Shin-Etsu Silicone Co., Ltd.). The powder to be treated is not particularly limited as long as it is a substance substantially insoluble in water and oil such as pigment and ultraviolet absorber, and examples thereof include titanium oxide, iron oxide, ultramarine blue, zinc white, magnesium oxide, zirconium oxide. , Mica, sericite,
Inorganic pigments such as talc, silica, kaolin, chromium hydroxide and carbon black; nylon powder, polymethylmethacrylate, styrene-divinylbenzene copolymer,
Organic powder such as polyethylene powder and fine particles of titanium oxide,
Examples thereof include ultraviolet absorbers such as fine particle zinc oxide and plate-shaped zinc oxide.

The method of treating the powder with a fluorine compound is not particularly limited, but for example, the fluorine compound is heated and dissolved in an organic solvent such as benzene, toluene, and acetone, and the powder is added thereto, and the solvent is distilled off after stirring. And a method of coating the powder with a fluorine compound. After coating, the powder may be baked at a temperature higher than the melting point of the fluorine compound in order to adapt the powder to the fluorine compound. Also, as a pretreatment for coating with an organic solvent, the powder was
If you bake under reduced pressure for about 80 minutes and dry the powder,
The water repellency after coating is further increased. In these coating treatments, two or more powders may be mixed and used at the same time. Further, it may be simultaneously treated with other known coating agents such as silicon other than fluorine compounds, higher fatty acids, higher alcohols, esters, waxes, etc. within a range that does not impair the effects of the present invention.

The treatment amount of the fluorine compound varies depending on the kind thereof, but is preferably 0.1 to 50% by weight of the powder (hereinafter, simply indicated by%), particularly 2 to 20%. If the amount of the fluorine compound is too small, sufficient water repellency cannot be obtained, and if the amount of the fluorine compound is too large, the original good spreadability of the extender pigment may be impaired.

The fluorine compound-treated powder can be used singly or in combination of two or more, and is 5 to 95% in the total composition, preferably 5 to 95%.
70% blended.

The fluorine-based oil agent as the component (B) is a perfluoroorganic compound that is liquid at room temperature, and includes, for example, perfluorodecalin, perfluoroadamantane, perfluorobutyltetrahydrofuran, perfluorooctane, perfluorononane, perfluoropentane, and perfluoropentane. Examples thereof include fluorodecane, perfluorododecane, and perfluoropolyether represented by the general formula (II).

Indicates a number of 0 or more that is 00,000. However, p = q = r =
It will never be zero. The perfluoro groups shown in parentheses here do not have to be arranged in this order, and random polymerization or block polymerization may be used. As such a perfluoropolyether, a liquid one having a viscosity of 5 to 5,000 cSt is particularly preferable. For example, the following general formula (III) (In the formula, x and y are numbers having a molecular weight of 500 to 10,000, and x / y is 0.2 to 2.) FOMBLIN HC-04 (average molecular weight 1,500), the same HC
