[0002]

2. Description of the Related Art Aqueous solid cosmetics have been applied to cosmetics such as foundations because they have a fresh feeling of use and are excellent in portability.
However, in conventional aqueous solid cosmetics, in order to enhance the adhesion to the skin and the moisturizing effect after finishing, the only option is to blend a large amount of a polyhydric alcohol or an oil agent. This may cause problems such as so-called shiny phenomena and sticky feeling on the coated surface. Furthermore, in order to reduce the shiny phenomenon and the sticky feeling, a large amount of powder is added, and as a result, the solid strength is reduced and the shape retention may not reach a satisfactory level.

[0003]

A water-based solid cosmetic containing 0.8 of a lipophilic surfactant, a powder and a partially crosslinked organopolysiloxane, spreads, is fresh, has a good feeling of use such as adhesion to the skin, The present inventors have found that an aqueous solid cosmetic composition having an excellent moisturizing effect after the finish and a long-lasting makeup, and also having an excellent shape-retaining property can be obtained, thereby completing the present invention. Further, an aqueous solid cosmetic containing powder treated with agar and / or gelatin and a lipophilic surfactant having an IOB value of 0.2 to 0.8 spreads, becomes fresh, and adheres to the skin. It has been found that a water-based solid cosmetic having excellent moisturizing effect after finishing and excellent cosmetic continuity, and also excellent shape retention, can be obtained while having a good feeling in use such as properties.

That is, the present invention provides the following components (a) to
(D); (a) agar and / or gelatin; (b) a lipophilic surfactant having an IOB value of 0.2 to 0.8; (c) powder; and (d) a partially crosslinked organopolysiloxane. A feature of the present invention is to provide a water-based solid cosmetic.
