Abstract
A material for removing offensive odors, which efficiently removes offensive odors, especially aldehydes, without being influenced by the ambient atmosphere such as humidity. It contains at least one acid salt selected from the group consisting of acid salts of aniline halides, acid salts of esters of aminobenzoic acid, acid salts of sulfanilamide or its derivatives, acid salts of aminoacetanilide and acid salts of aminoacetophenone. It may be supported on a porous carrier. The removing capacity of the material is not lowered by the variation of the ambient atmosphere of humidity and temperature. The material efficiently removes aldehydes.
