摘要：
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.
