摘要:
The objective of this invention is to provide an oily external composition for skin having an excellent rough skin recovering/preventing effect, and wherein powder is well dispersed in oil. An oily external composition for skin of this invention is characterized in that comprising a complex powder (the surface of lipophilic base powder is covered with zinc oxide) and an oil component, wherein said complex powder is dispersed in said oil component, and wherein zeta-potential of said lipophilic base powder is negative value at pH on skin. It is preferable that zeta-potential of said lipophilic base powder is −10 mV or less at pH on skin. It is preferable that said lipophilic base powder is swelled in the condition of dispersing in oil. Above-mentioned external composition can be used as a rough skin recovering composition and a sensitive skin caring composition.

摘要:
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.
