DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is a cosmetic in the form of a powder, but liquefies when it is rubbed at the time of use to produce a liquid-like property, and has a good feeling of use such as lack of powderiness and emollient feeling. The present invention relates to a powder cosmetic having a finished feeling and no squeaky feeling during use.

[0002]

2. Description of the Related Art
As powdery cosmetics, white powder, whitening powder, and the like are known, but there are problems such as scattering of powder during use, powdery finish, and dry skin. Further, for the purpose of promoting penetration of the drug into the skin, imparting moisture, oil content, moisturizing properties, emollient properties, and the like, a method in which powder cosmetics are mixed with water, oil, liquid cosmetics, and the like is used. However, there was a problem in terms of usability and the like.

As a technique for solving such a problem, as disclosed in JP-A-5-65212, JP-A-6-166611, and JP-A-6-21620, a hydrophobic material having a specific surface area is disclosed. Cosmetic powder coated with a specific fluorine compound such as silicic anhydride and perfluoroalkyl phosphate, a specific amount of an oily component and water are combined, and powder cosmetics are liquefied by rubbing. . However, although these powder cosmetics have solved the above-mentioned problems, they are not always at a satisfactory level in terms of lack of powderiness, emollient feeling and squeaky feeling during use.

[0004] For this reason, it is excellent in usability even in the form of a powder, and has a liquid-like property, a good feeling of use such as lack of powderiness and an emollient feeling and a finished feeling, and a feeling of creaking during use. No powder cosmetics were desired.

[0005]

Under such circumstances, the present inventors have conducted intensive studies, and as a result, have obtained a compound-treated powder having a specific hydrophobized silicic anhydride and a specific perfluoropolyether group and an aqueous component. If used in powdered form, it is a cosmetic in powder form, but has a liquid-like property such as providing a refreshing sensation during use, affinity for the skin, and being able to impart moisture and the like. The present inventors have found that a powder cosmetic which is excellent in use feeling and finish feeling such as emollient feeling and has no squeaky feeling during use can be obtained, and completed the present invention. Furthermore, it has been found that when an oily component is added in addition to the above components, the feeling of use such as no emollient feeling and no squeaky feeling is further improved.

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

/ G), and silicic anhydride treated with the specific perfluoropolyether compound (1) or (2) described later. These hydrophobized silicic anhydrides must have a surface area of at least 80 m ² / g by the BET method. If the surface area is less than this, a large amount cannot be oriented on the surface of the aqueous component, and the aqueous component cannot be stabilized. Can not be powdered.

When each component is within the above range, when rubbed, it liquefies to produce a liquid-like property, has a good feeling of use and finish such as lack of powderiness and an emollient feeling, and a feeling of squeak during use. Powder cosmetics having the effects of the present invention, such as no cosmetics, can be realized. Further, the above (a) to
It is preferable to add the component (d) in an amount of 0.5 to 40% in addition to the component (c) because the emollient feeling is further improved and the feeling of creaking during use is further reduced.
