DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic, and more particularly, to a cosmetic containing a liquid perfluoroorganic compound, a specific sustained-release silicone and a highly oil-absorbing powder, and having a refreshing feeling. By applying water and oil repellency to the applied cosmetic film, it is possible to prevent the disappearance of cosmetic ingredients such as medicinal ingredients and pigments due to sweat or sebum, to prevent makeup collapse such as facial shine due to aging, and to maintain the initial state. Regarding cosmetics that can be made.

[0002]

2. Description of the Related Art Generally, sweat, tears, tears, and the like, which are caused by loss of cosmetic ingredients such as medicinal ingredients and pigments, and aging of the face due to aging, oil floating, color dullness, and the like. There are internal factors due to the action of human secretions such as sebum, and external environmental factors such as skin movement, contact with hands or clothing, and rain (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 cause of makeup collapse due to sebum. As volatile oils, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, etc. are usually used from the viewpoint of safety and feeling of use, and if these are used as the main components of oil, sebum seizures are prevented. However, since these have a high volatilization rate and volatilize in ten minutes after application,
There has been a problem that the finished state is poor such as the feeling after application becomes powdery and the face is stiff.

On the other hand, in recent years, liquid perfluoro organic compounds (JP-A-61-234928 and JP-A-63-107911) have been used for imparting water resistance, sebum resistance and oil resistance to cosmetics. It has been proposed to. However, perfluoro organic compounds are hardly compatible with other additives commonly used in cosmetics, and only perfluoro organic compounds are used as oils, especially when used in large amounts in emulsified cosmetics. It is difficult to obtain, and there are drawbacks such as heavy stretch in use and lack of refreshing feeling.

[0005] Accordingly, there has been a demand for a cosmetic composition which is excellent in feeling of use without impairing the performance of a liquid perfluoro organic compound.

[0006]

Under these circumstances, the present inventors have conducted intensive studies and as a result, have found that a liquid perfluoro organic compound and a specific sustained-release silicone having a volatilization rate close to the sebum generation rate and a high oil absorption property. It has been found that the use of a combination of powders provides a cosmetic that can provide a refreshing feeling with good use, prevent the makeup from being disintegrated by sebum, and maintain the initial state of application.

That is, the present invention provides the following components (A) to
