The problem addressed by the present invention is the provision of a deodorant for the suppression of body odor, particularly the "old person smell" which is inherent to people of middle- and old-age, the deodorant being safe to use and having a strong deodorizing effect. By having the agent contain oolong tea extract and/or Chinese blackberry tea extract as active ingredients, it is possible to deodorize unsaturated aldehydes, which are the main cause of "old person smell".
