Abstract:
A complex powder comprising an adsorption site and operation site, wherein said adsorption site attracts or adsorbs a specific enzyme, wherein said operation site inhibits or activates said enzyme, and wherein each of the both sites are appeared on the surface of the powder. In the complex powder described above, it is preferable that ζ-potential of the adsorption site at the pH employed is negative value, wherein said adsorption site attracts or adsorbs the specific enzyme whose ζ-potential is positive value, and wherein said adsorption site inhibits or activates said specific enzyme. And it is preferable that said adsorption site has ζ-potential at pH7.5 of −10 mV or below.In the complex powder described above, it is preferable that said specific enzyme is a plasminogen activator, and the operation site inhibits said plasminogen activator.The complex powder described above can be used as an external composition for improving a rough skin and an external composition for a sensitive skin.
