A microcapsule includes a first encapsulation part composed of two first half shells between which a first space is defined. A second encapsulation part is located in the first space and composed of two second half shells between which a 5 second space is defined. A third encapsulation part is located in the second space and composed of two third half shells between which a third space is defined. The three spaces receive different components of a hydrogen-water agent such that the different components are not in contact with each other too early and do not contact outside air. |
