The composite powder according to the present invention is characterized in that an adsorption site for sucking or adsorbing a specific enzyme and an action site having inhibitory or activating properties of the enzyme are respectively expressed. In the above composite powder, it is suitable to aspirate or adsorb, inhibit or activate a specific enzyme having a negative value of the ζ potential at the adsorption site and a positive value of the ζ potential at the pH used. In addition, the adsorption site is preferably a site where the ζ potential is -10 mV or less at pH 7.5. In the above composite powder, the specific enzyme is a plasminogen activator, and the action site is preferably one having a plasminogen activator inhibitory action. The composite powder can be used as skin roughness improving agent and sensitive skin care agent. The skin external preparation for skin roughness improvement or the skin external preparation for sensitive skin which concerns on this invention contains the said composite powder 1 type, or 2 or more types. |
