Abstract: A method for preparing porous inorganic particles is disclosed. The method includes the steps of: (a) preparing an emulsion comprising an inorganic precursor and a polar solvent; (b) adding an organic solvent to the emulsion of step (a) to swell emulsion particles; (c) mixing the swollen emulsion of step (b) with polymer particles having a positive charge on the surface thereof; (d) adding a surfactant to the mixture of step (c) and removing the organic solvent; (e) adding an initiator to the result of step (d) to polymerize the same; and (f) firing the result of step (e) to remove the polymer particles so as to form macropores.

Abstract: The present invention relates to self-assembly type Janus microparticles and a preparation method therefor. The present invention can be used for preparing Janus microparticles in which a degree of phase separation is precisely controlled, for realizing stable interfacial orientation by selectively coating only one side of particles with a metal oxide, and for mass-producing Janus microparticles which have a degree of phase separation precisely controlled and exhibit extreme amphiphilicity in an anisotropic structure. Therefore, the Janus microparticles and the preparation method therefor according to the present invention can be widely used in various fields, thus contributing to industrial development.

Abstract: The present invention relates to a capsule comprising a pigment and a method for producing the same. More specifically, the present invention relates to a capsule which comprises therein a pigment inside which is likely to be discolored due to external environment, and thereby can easily crack or break and cause color development when applied to the skin, while isolating the pigment from the external environment, and a method for producing the same.

Abstract: The present invention relates to a makeup cosmetic composition containing capsules containing pigments in an inner layer thereof and, more specifically, to a makeup cosmetic composition, which contains a pigment in an inner layer and blocks a pigment from an external environment, thereby preventing pigment discoloration caused by the external environment, and contains capsules readily broken so as to enable color to show when applied to the skin, thereby showing color when applied to the skin even though the color of a formulation is nearly colorless and having an excellent skin coloring ability.
