Abstract
The present invention relates to a composite powder of scoria powder and a porous polymer. More particularly, the present invention relates to a composite powder (scoria sphere) in which the surface and the inside of a porous polymer are uniformly impregnated with scoria powder particles prepared by spraying in one-step a dispersion in which scoria powder is dispersed in a solution in which a polymer is dissolved; a cosmetic composition containing the same; and a process for producing the same. When the scoria impregnated powder, of the present invention, in which the porous polymer is uniformly impregnated with the scoria powder particles, is formulated as a cosmetic composition, the porous polymer supplements the sebum absorption performance of the scoria miniaturized in a micro size, and thus the sebum absorption power is greatly improved.
