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.

Claims3

Dependent claims

A method for manufacturing a composite powder in which jade powder particles are impregnated in a porous polymer, comprising:

spray-drying or electro-spraying a dispersion in which jade powder is dispersed in the porous polymer solution to manufacture the composite powder,
wherein the jade powder particles are impregnated at a content of 50 to 90% by weight, based on the total weight of the composite powder,
wherein the porous polymer is poly(methyl methacrylate),
wherein the composite powder has an average pore size of 250 to 600 nm, and
wherein the composite powder has a porosity of 40 to 85%.
