Particularly, there are sulfur compounds such as hydrogen sulfide and mercaptan, ammonia and aldehyde, and these various odorous gases can be removed. There has been increasing public interest in deodorants, and methods such as masking using fragrances, adsorption using activated carbon, and redox reactions using ozone, sodium hypochlorite, etc. have been proposed.

ましくない。[0004] The method using an aromatic is not a method for directly removing malodorous substances, and thus is not suitable for a case where the malodor is strong. The method using activated carbon has a short deodorizing life and has a black colored resin or resin. It was unsuitable for mixing in paper. Further, a method using ozone or sodium hypochlorite is not preferable because generated ozone or chlorine is harmful to a human body.
