DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cosmetics, and more particularly to cosmetics, which are excellent in water repellency and water resistance and also have oil resistance. The present invention relates to a cosmetic composition which has good elongation on the skin, has a good feel, and is more stable.

[0002]

2. Description of the Related Art Silicone oils are widely used because they have smoother usability and are superior in water repellency as compared with hydrocarbon oils. Oil is used in cosmetics because it has good elongation at the time of application and volatile silicone oil volatilizes as it elongates, so that it has good adhesion and is hardly broken by sweat. However, conventional cosmetics using only silicone oil have a problem that cosmetic components are easily lost due to sebum or the like.

On the other hand, in recent years, powders treated with a fluorine compound for the purpose of improving water resistance, sebum resistance and oil resistance of cosmetics and preventing makeup collapse (JP-A-55-167209; Sho 62-250074, JP-A-2-218603, U.S. Patent No. 363274
No. 4) has been proposed. However, such a powder has a drawback that it is difficult to disperse in an oil agent usually used for cosmetics, and particularly, it is difficult to obtain a uniform cosmetic when incorporated into an emulsified cosmetic.

Accordingly, an object of the present invention is to provide a stable cosmetic composition which does not impair the performance of the powder treated with a fluorine compound, has an excellent feeling in use, and is stable.

[0005]

Means for Solving the Problems As a result of intensive studies to achieve the above object, the present inventor has found that by using a lipophilic nonionic surfactant and silicone oil as an oil phase component, a powder of a fluorine compound-treated powder can be obtained. The inventor of the present invention has found that it is possible to obtain a stable cosmetic composition that is excellent in feeling of use and does not impair the performance, and that the present invention is completed.

That is, the present invention provides (a) a lipophilic nonionic surfactant, (b) a silicone oil, and (c) a perfluoroalkyl
An object of the present invention is to provide a cosmetic comprising a fluorine compound-treated powder surface-treated with a phosphate ester compound having a group . Hereinafter, the cosmetic of the present invention will be described in detail. As the lipophilic nonionic surfactant of the component (a) used in the present invention, any commonly used lipophilic nonionic surfactant can be used, and particularly, a liquid lipophilic nonionic surfactant is preferable. thereof include sorbitan monooleate, sorbitan sesquioleate, sorbitan monolaurate, sorbitan fatty acid esters such as sorbitan trioleate, glycerol monooleate, fatty acid monoglycerides such as glycerol monolaurate, alpha-Monoisosu te a <br/> Li glyceryl ether And the like.

[0007] These lipophilic nonionic surfactants include
Species or a combination of two or more species can be used, and 0.1 to 5% by weight (hereinafter, simply referred to as "%"), preferably 0.3 to 2%, of the total composition. 0.1%
If it is less than 5%, the emulsifiability deteriorates. Also used in the present invention
As the silicone oil as the component (b), any silicone oil commonly used in cosmetics can be used, and volatile low molecular weight silicone oil or cyclic silicone oil is particularly preferred from the viewpoint of feeling of use. Specific examples of the silicone oil include dimethylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, and octamethylcyclotetrasiloxane.

These silicone oils can be used alone or in combination of two or more, and preferably 1 to 70% by weight (hereinafter simply referred to as “%”), more preferably 5 to 70% by weight in the whole composition. 50% is blended. If it is less than 1%, the feeling of use tends to be poor, and if it exceeds 70%, the long-lasting makeup tends to be poor, which is not preferable. Further, Pafuru perfluoroalkyl group-containing esters (see U.S. Pat. No. 363,274) or the like represented by the fluorine compound-treated powder of component (c) used in the present invention, for example the following general formula (I)
Powders treated with a phosphoric ester-based compound having an oloalkyl group may be mentioned.

[RfC _n H _2n O] _y PO (OM) _3-y (I) (wherein, Rf represents a perfluoroalkyl group having 3 to 21 carbon atoms or a perfluoroalkyl group, Alternatively, it may be branched and have a single chain length or a mixed chain length, where n is an integer of 1 to 12, and y is a number of 1 to 3. Represents hydrogen, an alkali metal, ammonium or substituted ammonium.) The base powder to be treated with a fluorine compound is not particularly limited as long as it is a substance substantially insoluble in water and oil such as a pigment and an ultraviolet absorber. For example, for example, titanium oxide, iron oxide, ultramarine, zinc white, magnesium oxide, zirconium oxide, mica,
Examples include inorganic pigments such as sericite, talc, silica, kaolin, chromium hydroxide, and carbon black; organic powders such as nylon powder, polymethyl methacrylate, styrene-divinylbenzene copolymer, and polyethylene powder; and organic dyes.

The above-mentioned powders treated with a fluorine compound can be used alone or in combination of two or more, and are blended in a total composition of 0.01 to 95%, preferably 0.1 to 85%. If it is less than 0.01%, it is difficult to obtain the effect, and 95%
If it exceeds, the feeling of use deteriorates, which is not preferable. In the cosmetic of the present invention, in addition to the above-mentioned essential components, components which are added to ordinary cosmetics may be added as necessary. For example, petrolatum, lanolin, ceresin, microcrystalline wax, carnauba wax, candelilla wax, higher fatty acids,
Solid and semi-solid oils such as higher alcohols, olive oil, jojoba oil, castor oil, squalane, liquid paraffin, liquid oils such as ester oil, diglyceride, triglyceride, water-soluble and oil-soluble polymers, water, inorganic and organic pigments, metal soap Coloring agents such as inorganic and organic pigments and organic dyes treated or treated with silicon, preservatives, antioxidants, pigments, thickeners, pH adjusters, fragrances, ultraviolet absorbers, humectants, blood circulation enhancers, cold Examples thereof include a sensitizer, an antiperspirant, a bactericide, and a skin activator. These optional components can be blended within a qualitative and quantitative range that does not impair the object and effects of the present invention.

The cosmetic of the present invention can be produced according to a conventional method, and can be applied as a makeup cosmetic such as a liquid foundation, a powder foundation, blusher, eye shadow, etc., and a medicated cosmetic such as a sunscreen agent. . A particularly preferred embodiment of the cosmetic of the present invention is a two-layer liquid foundation containing (d) an aqueous medium in addition to the components (a) to (c). Here, the aqueous medium means water alone or a mixed medium with a lower monohydric or polyhydric alcohol such as ethanol, glycerin, and propylene glycol which can be freely mixed with water.
It is preferably used in an amount of from 90 to 90%, particularly preferably from 20 to 70%. In this two-layer liquid foundation, the pigment layer settles,
Disperses easily when shaken.

[0012]

The cosmetic of the present invention has a fluorine compound-treated powder dispersed uniformly, is excellent in water repellency, sebum resistance and oil resistance, prevents the disappearance of cosmetic components such as pigments due to sweat or sebum, and has a cosmetic effect. It is highly sustainable.
