(Prior Art) Traditionally, solid foundations, especially the powder type solid foundations that are most widely used in the summer, use a dry or water-moistened sponge puff on the surface of the solid foundation, then It is preferred by many women because it has excellent functionality in that makeup can be completed simply by rubbing the skin surface.

However, although such a method is simple, on the other hand,
Solid foundation pigment particles do not adhere to the skin surface, so-called "powder finish", "powder feel", etc.
It has unpleasant sensory properties. Further, since the adhesiveness to the skin surface is poor, the color tone such as "discoloration" or "color sinking" changes significantly over time. Further, it has a defect that “makeup loss” easily occurs with the passage of time.

Also, if the surface of the solid foundation is rubbed with a sponge puff moistened with water many times, the sweat and sebum on the sponge puff when applying makeup, or the oils and fats contained in the milky lotion and cream used as the makeup base, become solid. It moves to the mold foundation surface, the foundation surface is condensed and fixed, and the solid foundation does not stick to the sponge puff surface no matter how much it is rubbed with the sponge puff, causing a so-called caking phenomenon, and it becomes impossible to use It has the drawback of

DISCLOSURE OF THE INVENTION Therefore, as a result of intensive studies to improve the above situation, the present inventor has found that at least one selected from the group consisting of a water-soluble zinc salt and a water-soluble aluminum salt is added to purified water in an amount of 0.1 to 2.0. weight%
