A first subject of the present invention is a composite powder, characterized in that it has an antibacterial and antifungal effect in which a basic powder, zinc oxide and / or basic zinc carbonate, and an alkali metal salt are combined.n n n In the composite powder, the basic powder is an adsorption site for adsorbing a specific enzyme, and the site where the zinc oxide and / or the basic zinc carbonate and the alkali metal salt are combined is an action site having the inhibitory or activating properties of the enzyme. In the composite powder, the ζ potential of the adsorption site at the pH on the skin is negative, and the ζ potential of the adsorption site at the pH 7.5 is preferably -10 mV or less, and a second subject of the present invention includes the composite powder. It is a cosmetic which is characterized by the above-mentioned, The said composite powder is characterized by the fact that it can also be used as a skin roughening agent, a sensitive skin care agent, and an acne skin care agent. |
