Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to cosmetics, and more particularly, it has excellent water repellency and water resistance, and is also oil resistant, so that makeup such as pigments that are removed by sweat or sebum can be removed. This invention relates to a cosmetic that prevents the loss of ingredients and has a long lasting makeup.

[Problems to be solved by conventional techniques and inventions] Conventionally,
Many water- and oil-repellent powders made by treating the powder with fluorine compounds are known (Japanese Patent Application Laid-open No. 167209/1983,
2-250074, JP-A-1-180811, U.S. Pat. No. 3,632,744, etc.).

On the other hand, cosmetics, especially makeup cosmetics, are required to have excellent water repellency, makeup durability, and the like. However, even when attempting to incorporate powder surface-treated with a fluorine compound to improve water repellency into the oil agents normally used in these cosmetics, the powder does not disperse uniformly into the oil agent, resulting in poor water repellency, etc. It was difficult to find cosmetics with excellent quality.

Therefore, the powder is uniformly dispersed and has excellent water repellency and water resistance.
In addition, there was a desire for cosmetics with long lasting makeup.

[Means to solve the problem]

Under these circumstances, the present inventors conducted intensive research and found that by using powder treated with a fluorine compound in combination with a fluorine-based oil, the powder is uniformly dispersed in the oil, and makeup such as pigments is removed by sebum. The present invention was completed based on the discovery that it is possible to obtain a cosmetic that has a significantly improved effect of preventing the loss of ingredients and has significantly improved makeup durability.

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

The fluorine compound-treated powder of component (A) used in the present invention is a powder having the general formula (I) [C, F, . . . , C total of 2. ．． 0 kot PO(DH)s-t (I
) (wherein m represents an integer of 1 to 20, n represents 1 to 5
1 or 2) (U.S. Pat. No. 3,632,744), fluoroalkyl di(oxyethyl)amine phosphoric acid ester (JP-A-62-250074)
No.), resins having perfluoroalkyl groups (JP-A-55-167209), tetrafluoroethylene resins, perfluoroalcohols, perfluoroepoxy compounds, sulfamide-type fluorophosphoric acids, perfluorosulfates, perfluorocarboxylic acids Salt, perfluoroalkylsilane (manufactured by Shin-Etsu Silicone, LP-IT, LP-47,
It is treated with a fluorine compound such as a silane coupling agent such as LP-8T. The powder to be processed is
There are no particular restrictions on substances that are substantially insoluble in water and oil, such as pigments and ultraviolet absorbers, such as titanium oxide, iron oxide,
Ultramarine blue, zinc white, magnesium oxide, zirconium oxide,
Inorganic pigments such as mica, sericite, talc, silica, kaolin, chromium hydroxide, and carbon black; Organic powders such as nylon powder, polymethyl methacrylate, styrene-divinylbenzene copolymer, polyethylene powder, and fine particles of titanium oxide and fine particles. Examples include ultraviolet absorbers such as 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, acetone, etc., the powder is added therein, and after stirring, the solvent is distilled off. An example of this method is to coat a powder with a fluorine compound. After coating, the powder may be baked in a ladle at a temperature equal to or higher than the melting point of the fluorine compound, so that the powder blends well with the fluorine compound. In addition, as a pretreatment for coating with an organic solvent, the powder was heated at 110°C for 3
If the powder is dried under reduced pressure for about 0 minutes to 80 hours, the water repellency after coating will further increase. In these coating treatments, two or more kinds of powders can be mixed and used at the same time.

In addition, it may be simultaneously treated with other known coating agents other than fluorine compounds, such as silicone, higher fatty acids, higher alcohols, esters, and waxes, as long as the effects of the present invention are not impaired.

Although the amount of the fluorine compound to be treated varies depending on the type thereof, it is preferably 0.1 to 50% by weight of the powder (hereinafter simply expressed as %), particularly 2 to 20%. If the amount of the fluorine compound is too small, sufficient water repellency cannot be obtained, and if it is too large, the inherent spreadability of the extender pigment may be impaired.

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

The fluorine-based oil agent (B) is a perfluorinated organic compound that is liquid at room temperature, such as perfluorodecalin, perfluoroadamantane, perfluorobutyltetrahydrofuran, perfluorooctane, perfluorononane, perfluoropentane, and perfluorinated oil. Examples include fluorodecane, perfluorododecane, and perfluoropolyether represented by general formula (n).
