Abstract: Provided is a three-layered capsule using a hollow silica capsule containing a stabilizer, a hydrogel polymer consisting of a polymer blend, and an appropriately hydrophobic polymer. The principal components of the present invention include a single-layered capsule formed from water-insoluble substances, a stabilizer, and a hollow silica; a double-layered capsule having a hydrogel polymer blend surrounding the outside of the single-layered capsule; and a three-layered capsule having a hydrophobic polymer surrounding the outside of the double-layered capsule.

Abstract: A capsule composition containing UV-blocking inorganic nanoparticles, and a preparation method thereof, in which the UV-blocking inorganic nanoparticles are embedded in hydrophilic polymer capsules using a water-soluble dispersing agent, so that when the composition is applied to the skin, the polymer forms a thin hydrogel film that keeps the inorganic nanoparticles contained in the capsules to prevent the inorganic nanoparticles from penetrating the skin.
