To provide a powder deodorant with the capability of deodorization increased by producing condensed water by soaking it in water to be expanded when used for a longer period of time than the retention time of an existing deodorant conventionaly a month, by regenerating it by pouring water into the dried/weathered deodorant after use for 20-30 days, and to provide a cold insulating material reducing the freight cost because of small volume having the unchanged quality and stable as the dry powder deodorant.

One side of the deodorant is a porous plastic film, the other side being a non-porous plastic film, and polyacrylic soda powder, zirconium hafnium oxide powder and aromatic polyvinyl acetal resin powder are inserted into the inside of the films at the center. The outer peripheral edges of the films are thermally sealed, and the sealed films are individually packaged as the deodorant. A number of the packaged deodorants are inserted into a large paper box, and plural containers for storing condensed water are stored at the same time. In addition, an aromatic piece is separately put in the paper box and the paper box is sealed. The sealed paper box is used as a deodorant set for the deodorant and cold reserving material.
