DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic which has excellent water and oil repellency, does not lose pigment or ultraviolet absorbing powder due to sweat or sebum, etc., and has excellent durability. Related to makeup method.

[0002]

BACKGROUND OF THE INVENTION Generally, the disappearance of cosmetic ingredients such as ultraviolet absorbing inorganic powders and pigments,
The causes of facial discoloration such as shininess, oil floating, and color fading due to aging are internal factors caused by the action of human secretions such as sweat, tears, and sebum, movement of the skin, contact with hands or clothing, and rain. There are external environmental factors such as (contact with water).

[0003] Of these, makeup collapse caused by sebum is particularly regarded as a problem, which is considered to be due to an increase in residual oil content and sebum generation after application of the product. That is, in general, cosmetics use volatile or non-volatile oils. However, when non-volatile oils are mainly used, other volatile components are easily affected by skin temperature and friction during application. , And non-volatile oil remains, and sebum generated with the lapse of time is added thereto, resulting in excessive wetting of the cosmetic ingredients as oil. This is a factor that causes makeup to be lost due to sebum. As volatile oils used in cosmetics, hydrocarbons such as liquid isoparaffin and cyclic silicones such as octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane are usually used from the viewpoint of safety and usability. The use of these as the main component of oil can prevent sebum collapse, but these volatile oils have a high volatilization rate and volatilize within tens of minutes after application. There is a problem that the feeling is powdery, the face is stiff, and the finished state is poor, and it is presently used together with a nonvolatile oil.

On the other hand, in recent years, powders treated with a fluorine compound have been added to cosmetics for the purpose of improving water resistance, sebum resistance and oil resistance and preventing makeup collapse (JP-A-55-16720).

No. 811 and JP-A-2-218603 and U.S. Pat. No. 3,632,744 are proposed. However, such powders are difficult to disperse in oils commonly used in cosmetics, and particularly difficult to obtain uniform cosmetics when blended in emulsified cosmetics, especially when used in combination with non-volatile oils. However, there is a problem that it is difficult to obtain the desired effect of preventing makeup collapse.

Under such circumstances, the present inventors have conducted intensive studies and found that the above problem can be solved by using a liquid perfluoro organic compound as an oil agent and using a fluorine compound-treated powder as a cosmetic component. Heading,
A patent application was filed (Japanese Patent Application No. 2-205136). However, both the liquid perfluoro organic compound and the fluorine compound-treated powder have poor compatibility with other cosmetic ingredients, and there are various restrictions in stably combining these two ingredients simultaneously. .

Accordingly, an object of the present invention is to provide a stable cosmetic which is excellent in the effect of preventing makeup collapse and which can greatly reduce the restrictions on the formulation of the components, and a cosmetic method using the cosmetic. It is in.

[0007]

Means for Solving the Problems As a result of intensive studies, the present inventors have found that liquid perfluoro organic compounds and fluorine compound-treated powders can be separately applied to the skin without blending them in the same cosmetic. However, it has been found that the above object is achieved by realizing a state of coexistence on the skin.

The present invention has been made based on the above findings, and comprises a cosmetic composition A containing a liquid perfluoro organic compound, and a cosmetic composition B containing a powder of a fluorine compound. The cosmetic composition A and the cosmetic composition B are separately constituted ,

It is intended to provide cosmetics used as such . Also,
The present invention is characterized in that the cosmetic composition A (or B) is applied, and then the cosmetic composition B (or A) is applied as a cosmetic method using the cosmetic of the present invention. It is intended to provide a makeup method.
