  • Patent number: 10624822
    Abstract: The present invention relates to a composite powder of jade powder and a porous polymer, and more specifically relates to a composite powder (jade sphere) in which jade powder particles are impregnated in a porous polymer, the composite powder being produced by spraying, in one step, a dispersion in which jade powder has been dispersed in a solution that dissolves porous polymers, and to a cosmetic composition containing the composite powder, and to a manufacturing method for the composite powder.
    Type: Grant

  • Patent number: 10472485
    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.

  • Patent number: 10278903
    Abstract: The present invention relates to composite powder having enhanced water repellency and oil absorbency by means of even impregnation of inorganic powder particles with a super-water-repellent porous polymer. The composite powder prepared by means of a one-step spraying procedure of electro-spraying or spray drying, according to the present invention, shows super water repellency and maximized oil absorbency by means of increased porosity of porous polymethyl methacrylate (PMMA) and even impregnation with titanium dioxide (TiO2) nanoparticles.
