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.

The present invention relates to a microcomplex containing a modified nanoparticle adsorbed on a host microparticle and to a process to obtain it. The microcomplex is particularly useful for photoepilation. The present invention also relates to a composition containing the microcomplex and to the method for enhanced photoepilation based on the microcomplexes.

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.

The instant disclosure relates to a composition for topical application to the skin comprising a first pearlescent uncoated pigment having an average particle size of 25 um or less; a second pearlescent pigment having an average particle size of 25 um or less, completely or partially coated with one or more layers of metal oxides; a first mica having an average size of 42 um or less, completely or partially coated with one or more layers of red iron oxide; and a second mica having an average size of 25 um or less, completely or partially coated with one or more layers of titanium dioxide. It also relates to methods of using said compositions.

A process of producing a surface-reacted calcium carbonate is described. In embodiments, a calcium carbonate-comprising material is treated with at least one H.sub.3O.sup.+ ion donor, carbon dioxide, and at least one water-soluble metal cation source in an aqueous medium to form an aqueous suspension of surface-reacted calcium carbonate. A surface-reacted calcium carbonate obtained by said process and its use are also described.
