Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to water resistance, oil resistance,
The present invention relates to a cosmetic that has excellent smoothness, can prevent makeup collapse due to sweat and sebum, and has excellent makeup durability. More specifically, by mixing the powder obtained by treating the surface of the powder with a specific fluorine-containing silicone, and a fluorine-based oil, sweat produced on the skin, the effect of preventing makeup collapse due to sebum is excellent, In addition, the present invention relates to a cosmetic having excellent feeling in use, particularly, fit and smoothness.

2. Description of the Related Art Cosmetic forms in which powders for cosmetics are blended include foundation, blusher, eyebrow, eyeshadow, body powder, sunscreen cosmetics and the like.
In recent years, there has been a great demand for these cosmetics for a long-lasting cosmetic effect and a long-lasting sunscreen effect. Accordingly, improvement of water resistance and oil resistance has been required for cosmetic powders to be incorporated in these cosmetics.

[0003] As a method for imparting water resistance to a powder, a method of treating the powder with silicone has conventionally been known.
Specifically, a method in which methyl hydrogen polysiloxane is mixed with a powder and the powder is treated by heating and baking (Japanese Patent Publication No. 45-2915), a method in which methyl hydrogen polysiloxane or dimethyl polysiloxane is dissolved in an organic solvent After that, the powder is treated by adding zinc octylate or the like as a crosslinking catalyst and baking the mixture (Japanese Patent Publication No. 45-18999). The powder is mixed with a metal hydroxide, coated and treated with methyl hydrogen. A method of treating a powder by a mechanochemical reaction using polysiloxane (JP-B-56-43264) is known.
However, these treated powders are not sufficient in water resistance and oil resistance, and have a problem that makeup is easily disintegrated due to sweat and sebum generated on the skin.

[0004] Therefore, in order to improve the water resistance and oil resistance of the powder, and to prevent makeup collapse due to sweat, sebum and the like, a method of treating the powder with a fluorine compound has recently been proposed. Specifically, a method of treating powder with Teflon (registered trademark) (JP-B-61-55481) and a method of treating powder with fluorinated acrylate (JP-B-61-488)
03) Method, treating powder with perfluoroalkyl phosphate diethanolamine salt (JP-B 5-869)
84) Method, treating powder with perfluoroalkylsilane (JP-A-2-218603, JP-A-4-19381)
6) A method has been proposed.

Since all of these powders are coated with a fluorine compound having an extremely low surface free energy on the surface of the powder, they have water and oil repellency and are not compatible with sweat and sebum. However, the dispersibility of the oil agent contained in the cosmetic is poor, and the agglomeration and color unevenness of the powder are liable to occur, and it is extremely difficult to incorporate the oil into the cosmetic. In addition, these powders have a drawback that, in terms of usability, the smoothness is deteriorated as compared to before the treatment.

[0006] In addition, silicone oil is blended for the purpose of imparting water repellency to cosmetics. Because silicone oil has excellent water repellency and has a smooth feeling of use,
It is widely used as a cosmetic ingredient. However, silicone oil is not sufficient in water resistance and oil resistance, and there is a problem that cosmetics containing silicone oil easily lose their makeup due to sweat and sebum generated on the skin.

For the purpose of imparting water resistance and oil resistance to cosmetics, cosmetics containing liquid perfluoropolyether (JP-A-61-234928 and JP-A-63-247214), fluorine-modified Cosmetics containing silicone oil (JP-A-5-247214, JP-A-6-12-1)
84312, JP-A-6-234858). However, although these fluorinated oils have water and oil repellency, they have high fluidity and poor adhesion to the skin, so they cannot sufficiently prevent makeup collapse against a large amount of sweat and sebum. There was a problem.

[0008]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cosmetic which is excellent in water resistance, oil resistance, adhesion and smoothness, can prevent makeup collapse due to sweat and sebum, and is excellent in long-lasting makeup. And

[0009]

Means for Solving the Problems In view of such circumstances, the present inventors have conducted intensive studies, and as a result, by treating the surface of the powder with a specific fluorine-containing silicone, water resistance, oil resistance, Powder that has excellent smoothness and good dispersibility in fluorinated oils can be obtained. By blending this treated powder with fluorinated oils, it has excellent water and oil resistance, adhesion, and smoothness. The present inventors have found that a cosmetic excellent in the effect of preventing makeup collapse due to sweat and sebum generated on the skin can be obtained, and completed the present invention.

That is, according to the present invention, (a) the surface of the powder is represented by the general formula (1) wherein R1 is the same or different
To 20 alkyl groups or aryl groups, R2 is -R5-
Rf (wherein, R5 represents a divalent alkylene group having 2 to 6 carbon atoms, Rf represents a perfluoroalkyl group having 1 to 12 carbon atoms.), R3 is -R5-SiX ₃ (wherein, X Represents an alkoxyl group having 1 to 4 carbon atoms or halogen.), R4 is any of R1 or R2 or R3, l, m, and n are integers, and l = 0 to 500, m

In particular, the present invention provides a cosmetic having excellent fit and smoothness.
