Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition, more specifically, it has excellent water repellency and water resistance, and also has oil resistance, and can prevent the disappearance of cosmetic ingredients such as pigments and ultraviolet absorbers due to sweat or sebum. The present invention relates to a cosmetic that prevents the skin from spreading, has good spreadability on the skin, has a good feel, and is stable.

[0002]

2. Description of the Related Art Silicone oils are widely used because they have smoother usability than hydrocarbon oils and are excellent in water repellency, and particularly volatile silicone oils. Oil is used in cosmetics because it spreads well during application, and since the volatile silicone oil volatilizes as it spreads, it has good adhesion and is resistant to sweat and collapse. However, the conventional cosmetics using only silicone oil have a problem that the cosmetic components are easily lost by sebum or the like.

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

Therefore, 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.

[0005]

Means for Solving the Problems As a result of earnest studies to achieve the above object, the present inventor has found that by using a lipophilic nonionic surfactant and a silicone oil as an oil phase component, The present invention has been completed based on the finding that a stable cosmetic having an excellent feeling of use can be obtained without impairing the performance.

That is, the present invention provides a cosmetic comprising (a) a lipophilic nonionic surfactant, (b) a silicone oil, and (c) a fluorine compound-treated powder. .. Hereinafter, the cosmetic material of the present invention will be described in detail. As the lipophilic nonionic surfactant as the component (a) used in the present invention, any one can be used as long as it is generally used, but a liquid lipophilic nonionic surfactant is particularly preferable. Specifically, sorbitan monooleate, sorbitan sesquioleate, sorbitan monolaurate, sorbitan trioleate, and other sorbitan fatty acid esters, glycerin monooleate, glycerin monolaurate, and other fatty acid monoglycerides, and α-monoisosulaallyl glyceryl ether and other alkyl glyceryl ethers. Examples include ether.

These lipophilic nonionic surfactants are 1
One kind or a combination of two or more kinds can be used, and 0.1 to 5% by weight (hereinafter, simply indicated by "%"), preferably 0.3 to 2% is blended in the entire composition. 0.1%
If it is less than 5%, the emulsifiability is deteriorated, and if it exceeds 5%, the makeup retention is deteriorated, which is not preferable. Also used in the present invention
As the silicone oil as the component (b), any silicone oil commonly used in cosmetics can be used, but a volatile low-molecular silicone oil or a cyclic silicone oil is particularly preferable from the viewpoint of feeling in use. Specific examples of such silicone oil include dimethylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, octamethylcyclotetrasiloxane, and the like.

These silicone oils may be used either individually or in combination of two or more, preferably 1 to 70% by weight (hereinafter simply referred to as "%") in the total composition, more preferably 5 to 50% is blended. If it is less than 1%, the feeling of use tends to be poor, and if it exceeds 70%, the makeup retention tends to be poor, such being undesirable. Further, the fluorine compound-treated powder of the component (c) used in the present invention has, for example, a perfluoroalkyl group-containing ester represented by the following general formula (I) (see US Pat. No. 363274) and a perfluoroalkyl group. Resin (see JP-A-55-167209), tetrafluoroethylene resin, perfluoroalcohol, perfluoroepoxy compound, sulphoamide type fluorophosphoric acid, perfluorosulfate, perfluorocarboxylate, perfluoroalkylsilane ( JP-A-2-218603
