The problem addressed by the present invention is to provide a deodorant for deodorizing body odor, particularly the "old person smell" inherent to middle- and old-aged people, the deodorant being safe to use and having a strong deodorizing effect. By having the deodorant contain polyvalent alcohol, in particular 1,3-butylene glycol, as an active ingredient, it is possible to provide a deodorant with an outstanding deodorizing effect. The deodorant is particularly effective in deodorizing unsaturated aldehydes, which are the main cause of "old person smell".本發明係提供用以抑制臭味，尤其中高年特有體臭之老年臭之安全且消臭效果高之消臭劑。提供藉由以多元醇，尤其1,3-丁二醇作為有效成份，具有優異效果之消臭劑。尤其有效於消除老年臭主要發生因素之不飽和醛臭味。
