Abstract: The present invention has revealed that an antiviral agent containing a serine protease such as subtilisin, nattokinase, and trypsin has an effect of inactivating non-envelope type viruses, and that combining such an antiviral agent containing a serine protease with a cationic polymer enhances the inactivation effect of the antiviral agent against non-envelope type viruses. As a result, an antiviral agent that is highly safe, that has a high virus inactivation ability, and that contains a component that is inexpensive in terms the manufacturing cost and a cationic polymer, was discovered.

Abstract: This application aims at providing a retainer of a cosmetic material and a method of manufacturing a cosmetic tool, which are capable of easily treating the cosmetic material even when decreasing a concentration of skin care ingredients of the cosmetic material produced by freeze-drying. A cosmetic tool (1) includes: a retainer (3) to include an annular frame (2) and a handle (5) for holding the frame (2); and a cosmetic material (4) to be produced by freeze-drying an aqueous solution of skin care ingredients and fixed in a way that covers an aperture of the frame (2).
